Revision	Date	Author	Comments
1.8	14-Jan-2014	christos	use new bsd.syscall.mk
1.7	20-Mar-2012	martin	branches: 1.7.2; 1.7.4; Remove spurious bsd.kinc.mk include, which seems to not be needed here and does not work at all (missing bsd.own.mk for ACTIVE_CC) anyway.
1.6	11-Dec-2005	christos	branches: 1.6.112; 1.6.116; merge ktrace-lwp.
1.5	26-Feb-2005	perry	make this rebuild generated files by default
1.4	15-Nov-2003	thorpej	branches: 1.4.8; 1.4.10; We have CVS; there is no reason to make .bak files when generating the syscall tables.
1.3	26-Oct-2003	lukem	Use ${HOST_SH} instead of `sh'. If necessary, pull in <bsd.sys.mk> to get the definition of HOST_SH; Makefiles that pull in one of (most of) <bsd.*.mk> will get this anyway.
1.2	25-Mar-1999	mrg	branches: 1.2.42; move sparc32 to netbsd32; split out MD part (signal handling) (mostly via repository copy, rename and perl -pi :-)
1.1	26-Aug-1998	mrg	add a 32-bit compatibility module for the sparc64 port, so it can run NetBSD/sparc binaries with a LP64 kernel.
1.2.42.4	04-Mar-2005	skrll	Sync with HEAD. Hi Perry!
1.2.42.3	21-Sep-2004	skrll	Fix the sync with head I botched.
1.2.42.2	18-Sep-2004	skrll	Sync with HEAD.
1.2.42.1	03-Aug-2004	skrll	Sync with HEAD
1.4.10.1	19-Mar-2005	yamt	sync with head. xen and whitespace. xen part is not finished.
1.4.8.1	29-Apr-2005	kent	sync with -current
1.6.116.1	05-Apr-2012	mrg	sync to latest -current.
1.6.112.2	22-May-2014	yamt	sync with head. for a reference, the tree before this commit was tagged as yamt-pagecache-tag8. this commit was splitted into small chunks to avoid a limitation of cvs. ("Protocol error: too many arguments")
1.6.112.1	17-Apr-2012	yamt	sync with head
1.7.4.1	18-May-2014	rmind	sync with head
1.7.2.1	20-Aug-2014	tls	Rebase to HEAD as of a few days ago.
1.56	19-May-2024	christos	version dup3
1.55	30-Jul-2023	rin	COMPAT_NETBSD32: Add support for epoll(2).
1.54	19-Dec-2022	pgoyette	Create compat_100 module infrastructure now that we have branched for NetBSD-10
1.53	17-Apr-2021	simonb	Compile in compat32 syscall names all the time, as we do for native syscall names. Needed for dtrace.
1.52	16-May-2020	christos	branches: 1.52.4; Add ACL support for FFS. From FreeBSD.
1.51	26-Apr-2020	thorpej	Add a NetBSD native futex implementation, mostly written by riastradh@. Map the COMPAT_LINUX futex calls to the native ones.
1.50	12-Mar-2020	pgoyette	Split out the quota code from the rest of compat_netbsd32 module. This allows loading of compat_netbsd32 on kernels that don't have ``options QUOTA'' enabled.
1.49	22-Sep-2019	christos	Add a new member to struct vfsstat and grow the unused members The new member is caled f_mntfromlabel and it is the dkw_wname of the corresponding wedge. This is now used by df -W to display the mountpoint name as NAME=
1.48	20-Aug-2019	christos	make things compile again.
1.47	20-Aug-2019	maxv	Disable netbsd32_drm.c until it receives proper review.
1.46	20-Aug-2019	christos	compat32 drm ioctl support from Surya Shankar at GSoC 2019
1.45	18-Jun-2019	christos	use option quota
1.44	27-Jan-2019	christos	remove dup
1.43	27-Jan-2019	pgoyette	Merge the [pgoyette-compat] branch
1.42	24-Dec-2018	mrg	quotactl is always included, regardless of options QUOTA.
1.41	24-Dec-2018	mrg	move mmap(), compat 40 mount(), pipe() and getfh() into their own files as the implementation is non trivial or is compat. mark old mount() properly instead of manually #if'ing ito to ENOSYS.
1.40	24-Dec-2018	mrg	move rlimit and quota code into their own modules. (netbsd32_netbsd.c should have only simple shims. anything more than copying arguments from one args struct to the other should not be placed in this file. still a couple more to move out.)
1.39	19-Oct-2016	skrll	branches: 1.39.14; 1.39.16; PR kern/51514: ptrace(2) fails for 32-bit process on 64-bit kernel Updated from the original patch in the PR by me.
1.38	03-Dec-2015	pgoyette	branches: 1.38.2; Missed these. Only include the compat_14 sys calls if this being compiled as part of the compat_netbsd32_sysvipc module.
1.37	01-Dec-2015	pgoyette	Properly mark netbsd32_mqueue.c to depend on 'options MQUEUE' Yes, MQUEUE is included in all kernels by default, but it can be removed. If it is removed, the compat_netbsd32 module should not include it, either.
1.36	22-Jun-2015	mrg	add netbsd32 support for nfssvc(2). we do this by defining 5 copyin/out functions that do all the ugly work, are just plain copyin/out for the native system calls, and do the necessary translations for netbsd32. with this i'm able to run 32 bit nfsd and mountd on 64 bit kernel and mount the file systems remotely.
1.35	20-Jun-2015	martin	Implement modctl, sigqueinfo and mq_*
1.34	17-Nov-2014	uebayasi	branches: 1.34.2; Define compat modules (but without dependencies yet).
1.33	29-Mar-2013	christos	branches: 1.33.10; compat glue for new lwp_park
1.32	10-Mar-2012	joerg	branches: 1.32.2; P1003_1B_SEMAPHORE is no longer optional.
1.31	19-Feb-2012	rmind	Remove COMPAT_SA / KERN_SA. Welcome to 6.99.3! Approved by core@.
1.30	04-Jan-2011	matt	branches: 1.30.8; 1.30.12; Make the SA support as optional as is possible.
1.29	10-Dec-2009	matt	branches: 1.29.4; Move saemul_netbsd32 to netbsd32_sa.c and allow the KERN_SA bits to be omitted.
1.28	11-Jan-2009	christos	merge christos-time_t
1.27	19-Nov-2008	ad	branches: 1.27.4; Make the emulations, exec formats, coredump, NFS, and the NFS server into modules. By and large this commit: - shuffles header files and ifdefs - splits code out where necessary to be modular - adds module glue for each of the components - adds/replaces hooks for things that can be installed at runtime
1.26	15-Oct-2008	wrstuden	branches: 1.26.2; Merge wrstuden-revivesa into HEAD.
1.25	18-Feb-2007	cube	branches: 1.25.38; 1.25.42; 1.25.44; 1.25.48; Add missing lwp syscalls. Put them all together into a new file, netbsd32_lwp.c, and remove remaining traces of SA. This still needs some MD (and possibly MI, depending on the chosen solution) changes to actually work.
1.24	09-Nov-2006	cube	branches: 1.24.4; - Make better use of COMPAT_XX type in syscalls.master - Remove useless (thanks to COMPAT_XX behaviour) #ifdefs in syscalls.master - Make netbsd32_compat_43.c compiled per COMPAT_LINUX32 because the latter needs stuff from it. Fixes Perry's PR#34951.
1.23	30-Aug-2006	cube	branches: 1.23.2; 1.23.4; netbsd32_core.c is need only under options COREDUMP.
1.22	29-Mar-2006	cube	Implement the _lwp* and sa_* families of syscalls, using the newly introduced hooks in the native code.
1.21	05-Mar-2006	cube	branches: 1.21.2; 1.21.4; 1.21.6; Implement the ksem_* family of syscalls.
1.20	11-Dec-2005	christos	branches: 1.20.4; 1.20.6; merge ktrace-lwp.
1.19	23-Oct-2005	cube	- Split sys_kevent into kevent1 so that it can be used by COMPAT_NETBSD32 code. - To achieve COMPAT_NETBSD32 compatibility, introduce a parameter to kevent1 that points to functions that do the actual copyin/copyout operations. This is similar to what was done in FreeBSD by Paul Saab. - Add the COMPAT_NETBSD32 definitions and hooks.
1.18	19-Aug-2005	christos	branches: 1.18.2; 64 bit inode changes.
1.17	17-Jun-2004	cube	branches: 1.17.12; o Add support for the statvfs family of syscalls (statvfs1, fstatvfs1, fhstatvfs1 and getvfsstat) o Move the statfs family out of netbsd32_fs.c and netbsd32_netbsd.c to netbsd_compat_20.c, compiled with COMPAT_20 Reviewed by christos@.
1.16	16-Jan-2004	mrg	clean up a little: - delete ktrsyscall32() - add a check #ifdef _LP64 to do the conversion if P_32 is set to the standard ktrsyscall() - add a couple of similar _LP64/P_32 checks to the systrace code. this should get systrace working for 32 bit apps as well as complete ktrace support for "trace_enter/trace_exit" using platforms such as amd64. XXX: systrace isn't supported on sparc64 currently... (it doesn't use trace_enter/trace_exit, or have it's own calls to systrace_xxx()...)
1.15	15-Jan-2004	mrg	add a copy of the ktrsyscall() entry point for 32 bit emulated calls. the main purpose of this function is to adjust the "argsize" value of the ktrace syscall record, otherwise userland will see N/2 (rounded down) arguments instead of N.
1.14	25-Oct-2003	chs	allow COMPAT_SUNOS without COMPAT_43.
1.13	15-Oct-2003	fvdl	Don't put the netbsd32_compat.c files in the 'compat library'. Unconditionally compiling these causes a ripple effect making it hard to conditionalize anything on COMPAT_ in the kernel.
1.12	29-Apr-2002	mrg	branches: 1.12.10; build the netbsd32_compat* objects into libcompat.a, so they are available to emulations not just netbsd itself. rename the compat_10 functions to match everything else. fixes a problem reported by julian coleman.
1.11	08-Dec-2001	thorpej	Make the coredump routine exec-format/emulation specific. Split out traditional NetBSD coredump routines into core_netbsd.c and netbsd32_core.c (for COMPAT_NETBSD32).
1.10	06-Jun-2001	mrg	branches: 1.10.2; add netbsd32_uvm_unix.c and netbsd32_kern_sig.c
1.9	08-Feb-2001	mrg	branches: 1.9.2; split up netbsd32_netbsd.c into 9 new files, leaving only those syscalls that have no special interpretations besides simple syscall args conversion.
1.8	07-Feb-2001	mrg	compat_sunos needs netbsd32_compat_09.c
1.7	01-Dec-2000	jdolecek	put a.out/elf32 specific things in netbsd32_exec_{aout\|elf32}.c emul_netbsd32 was moved to netbsd32_netbsd.c g/c netbsd32_exec.c now
1.6	11-Oct-1999	eeh	branches: 1.6.2; Add netbsd32_compat_14.c Rename everything from compat_netbsd32 -> netbsd32 so we don't have silly names like compat_14_compat_netbsd32_sys_shmctl().
1.5	24-Apr-1999	eeh	branches: 1.5.2; Don't defopt COMPAT_NETBSD32 here; it's done in sys/conf/files.
1.4	25-Mar-1999	mrg	branches: 1.4.4; clean and up make compile
1.3	25-Mar-1999	mrg	move sparc32 to netbsd32; split out MD part (signal handling) (mostly via repository copy, rename and perl -pi :-)
1.2	01-Oct-1998	eeh	Overhaul. Now will run simple things like /bin/sh and /bin/echo.
1.1	26-Aug-1998	mrg	add a 32-bit compatibility module for the sparc64 port, so it can run NetBSD/sparc binaries with a LP64 kernel.

1.139	11-Nov-2021	martin	Adapt to recent posix_spawn extensions.
1.138	06-Nov-2021	thorpej	COMPAT_NETBSD32 is all about running the 32-bit flavor of native binaries on a 64-bit platform[], as such: - Make the logic about which "sendsig" flavor to call MI (as it is in the native 64-bit environment) and follow the same rules as the native 32-bit environment. - Make COMPAT_NETBSD32 x COMPAT_16 work the same as it would in the native 32-bit environment by providing a netbsd32_sendsig_sigcontext_16_hook, rather than overriding the entire sendsig logic with a netbsd32_sendsig_hook. - In netbsd32___sigaction_sigtramp(), make sure the compat_netbsd32_16 module is loaded if the trampoline version specifies a sigcontext style handler, otherwise return EINVAL so that libc can try again with siginfo style. [] ...except for arm32, which uses it to mean "run 32-bit OABI binaries from the 32-bit EABI environment". Doing it this way was arguably a mistake, but we are stuck with it for now, so support it by providing a machine- dependent override for netbsd32_sendsig() that also disables the corresponding logic in netbsd32___sigaction_sigtramp(). Fixes PR kern/56487.
1.137	19-Jan-2021	simonb	The read/write/send/recv system calls return ssize_t because -1 is returned on error. Therefore we must restrict the lengths of any buffers to NETBSD32_SSIZE_MAX with compat32 to avoid garbage return values. Fixes ATF lib/libc/sys/t_write:write_err.
1.136	18-Jan-2021	simonb	s/u_intN_t/uintN_t/
1.135	14-Jan-2021	simonb	Handle FSSIOCSET and FSSIOCGET; vndconfig(8) works with compat32 now. XXX: FSSIOCSET50 and FSSIOCGET50 are not (yet) handled.
1.134	01-Nov-2020	pgoyette	Separate the compat_netbsd32_coredump from the compat_netbsd32 and coredump modules, into its own module. Welcome to 7.99.75 !!!
1.133	16-May-2020	christos	branches: 1.133.2; Add ACL support for FFS. From FreeBSD.
1.132	24-Dec-2019	kamil	Introduce PT_LWPSTATUS + PT_LWPNEXT, obsolete PT_LWPINFO PT_LWPINFO is a legacy ptrace(2) operation that was originally intended to retrieve the thread (LWP) information inside a traced process. It has a number of flaws and is confused with PT_LWPINFO from FreeBSD. PT_LWPSTATUS and PT_LWPNEXT address the problems (shortly by: rename, removal of pl_event) and introduces new features: signal context (pl_sigpend, pl_sigmask), LWP name (pl_name), LWP TLS base address (pl_private). The private pointer was so far missing information for a debugger. PT_LWPSTATUS@nnn is now shipped with core(5) files and contain LWP specific information, so far missed in the core(5) files. PT_LWPSTATUS retrieves LWP information for the prompted thread. PT_LWPNEXT retrieves LWP information for the next thread, borrowing the semantics from NetBSD specific PT_LWPINFO. PT_LWPINFO is namespaced with __LEGACY_PT_LWPINFO and still available for the foreseeable future, without plans of removing it. Add ATF tests for PT_LWPSTATUS + PT_LWPNEXT. Keep ATF tests for PT_LWPINFO. Switch GDB to new API. Proposed on tech-kern@.
1.131	18-Nov-2019	rin	8-byte objects on i386 or arm-oabi are aligned in 4-byte boundary. Therefore, we must use __attribute__((__aligned__(4))) for them. netbsd32_{,u}int64 are provided for this purpose. However, we cannot use it in <compat/sys/siginfo.h> due to circular dependency b/w <machine/netbsd32_machdep.h>. In order to distangle it, we choose here to have a duplicate type, netbsd32_siginfo_uint64, in <compat/sys/siginfo.h>. The equivalence with netbsd32_uint64 is asserted in <compat/netbsd32/netbsd32.h>. Now, gdb for i386 works again on amd64 kernel. Based on patch provided by kamil. Thanks! XXX pullup to netbsd-9
1.130	18-Nov-2019	rin	Sorry, revert unintentional parts of the previous commit: http://mail-index.netbsd.org/source-changes/2019/11/18/msg110946.html I was going to commit only netbsd32_signal.c.
1.129	18-Nov-2019	rin	Belatedly catch up with kern_sig.c rev 1.358: http://cvsweb.netbsd.org/bsdweb.cgi/src/sys/kern/kern_sig.c#rev1.358 Provide syscall information with SIGTRAP TRAP_SCE/TRAP_SCX so that picotrace/truss, for example, works fine on COMPAT_NETBSD32. With some minor changes: - Centralize netbsd32_si{,32}_si{32,}() into netbsd32_ksi{,32}_ksi{32,}(). - Provide si_status with SIGCHLD. - Remove the remaining of SA. XXX pullup to netbsd-9
1.128	07-Nov-2019	rin	For netbsd32_statvfs, f_spare should be netbsd32_uint64, not uint64_t. Fix syscalls using struct statvfs on COMPAT_NETBSD32 on amd64, where NETBSD32_INT64_ALIGN is __attribute__((__aligned__(4))).
1.127	03-Oct-2019	kamil	Switch kevent udata from intptr_t void* Synchromize the struct field format with other BSDs and Darwin. No ABI change between older and newer struct form on the ports. The change will require no changes to most C users during the transition period as the header keeps a caller cast. Discussed with core@ and there were no objections for this move.
1.126	26-Sep-2019	christos	accrightslen should be u_int for compat too
1.125	25-Sep-2019	christos	avoid signed-compare warning; use uintmax_t to print.
1.124	22-Sep-2019	christos	Add a new member to struct vfsstat and grow the unused members The new member is caled f_mntfromlabel and it is the dkw_wname of the corresponding wedge. This is now used by df -W to display the mountpoint name as NAME=
1.123	20-Feb-2019	mrg	branches: 1.123.4; use KASSERTMSG() in netbsd32_ptr32i().
1.122	09-Feb-2019	mrg	- expand the comment about what netbsd32_machdep.h should provide. - add missing NETBSD32_POINTER_TYPE - add static inline functions to convert pointers to/from 32 bit, inclusing an overflow check for NETBSD32PTR32PLUS().
1.121	27-Jan-2019	pgoyette	Merge the [pgoyette-compat] branch
1.120	25-Nov-2018	mlelstv	Restore netbsd32 compat code for new NPF ABI.
1.119	11-Aug-2018	mrg	support nullfs in netbsd32.
1.118	10-May-2018	christos	branches: 1.118.2; add {send,recv}mmsg
1.117	14-Apr-2018	mrg	redo the previous -- compat/sys/siginfo.h is already included later, as is another header. move them up near the top.
1.116	18-Dec-2017	mrg	branches: 1.116.2; include <compat/sys/siginfo.h> for siginfo32_t.
1.115	17-Dec-2017	christos	handle siginfo requests for ptrace32
1.114	13-Nov-2016	rin	branches: 1.114.8; tv_usec in netbsd32_timeval is suseconds_t (aka int32_t) rather than netbsd32_long (considered harmless) approved by martin
1.113	19-Oct-2016	skrll	PR kern/51514: ptrace(2) fails for 32-bit process on 64-bit kernel Updated from the original patch in the PR by me.
1.112	23-Sep-2016	skrll	Trailing whitespace
1.111	23-Sep-2016	skrll	Types for wait6 and clock_getcpuclockid2
1.110	17-Sep-2016	christos	deal with not having KTRACE
1.109	26-Nov-2015	martin	branches: 1.109.2; We never exec(2) with a kernel vmspace, so do not test for that, but instead KASSERT() that we don't. When calculating the load address for the interpreter (e.g. ld.elf_so), we need to take into account wether the exec'd process will run with topdown memory or bottom up. We can not use the current vmspace's flags to test for that, as this happens too early. Luckily the execpack already knows what the new state will be later, so instead of testing the current vmspace, pass the info as additional argument to struct emul e_vm_default_addr. Fix all such functions and adopt all callers.
1.108	10-Aug-2015	mrg	move some header-specific pointer-typedefs into a header-specific area.
1.107	22-Jun-2015	mrg	add netbsd32 support for nfssvc(2). we do this by defining 5 copyin/out functions that do all the ugly work, are just plain copyin/out for the native system calls, and do the necessary translations for netbsd32. with this i'm able to run 32 bit nfsd and mountd on 64 bit kernel and mount the file systems remotely.
1.106	21-Jun-2015	mrg	s/sparc64/native 64 bit/ in a comment...
1.105	21-Jun-2015	martin	Implement trivial conversion for pset_*
1.104	20-Jun-2015	martin	Implement modctl, sigqueinfo and mq_*
1.103	05-Oct-2014	christos	branches: 1.103.2; add tmpfs.
1.102	28-Jun-2014	dholland	branches: 1.102.2; Revert the following changes: src/sys/sys/quotactl.h 1.37 src/sys/compat/netbsd32/netbsd32.h 1.101 src/sys/compat/netbsd32/netbsd32_netbsd.c 1.188, 1.189 src/sys/kern/vfs_quotactl.c 1.39 src/sys/kern/vfs_syscalls.c 1.483 src/sys/ufs/lfs/ulfs_quota.c 1.11 src/sys/ufs/ufs/ufs_quota.c 1.116 src/lib/libquota/quota_kernel.c 1.5 and do them correctly. If you're going to change the name of something, you need to change the name of all the things with the same name, not just a handful, and you should change it to something similar so it still matches the rest of the system rather than just picking an arbitrarily different name. Hi, Joerg. To wit, rename the quotactl "delete" operation to "del", because "delete" is a reserved word in C++ and for some reason Joerg wants to run internal interfaces used only by C code through his C++ compiler. Do not rename it to "remove" instead, because this doesn't match libquota or the rest of the usage throughout the system; and rename all the related identifiers, not just the ones that blew the mind of Joerg's C++ compiler. Because this is not a user-facing API (the only userland consumer sys/quotactl.h is libquota) it is sort of ok to make arbitrary source-incompatible changes; however, by the same token it's completely unnecessary. If it were a user-facing API that someone might have a semi-rational reason to want to run a C++ compiler on, it would be incorrect to change it at this point.
1.101	13-Jun-2014	joerg	delete -> remove
1.100	30-Apr-2014	njoly	Do not use native off_t type under compat netbsd32, but a new netbsd32_off_t that provide the expected alignment for 64bit types.
1.99	03-Feb-2014	manu	branches: 1.99.2; Properly translate struct swapent for COMPAT_NETBSD32 (missing commit)
1.98	24-Jan-2014	christos	sigaction until 1.4 had an int sigmask, don't trash the stack.
1.97	01-Jan-2014	dsl	Change the type of the 'cookie' that holds the state of the core dump file from 'void ' to the actual type 'struct coredump_iostate '. In most of the code the contents of the structure are still unknown. This just stops the wrong type of pointer being passed to the 'void *' parameter. I hope I've found everything, amd64 GENERIC and i386 GENERIC & ALL compile.
1.96	12-Oct-2012	christos	branches: 1.96.2; fix pre-5 stat system call structure which should have used the pre-64-time_t timestamps!
1.95	08-Apr-2012	martin	branches: 1.95.2; Rework posix_spawn locking and memory management: - always provide a vmspace for the new proc, initially borrowing from proc0 (this part fixes PR 46286) - increase parallelism between parent and child if arguments allow this, avoiding a potential deadlock on exec_lock - add a new flag for userland to request old (lockstepped) behaviour for better error reporting - adapt test cases to the previous two and add a new variant to test the diagnostics flag - fix a few memory (and lock) leaks - provide netbsd32 compat
1.94	06-Mar-2012	macallan	allow mounting ext2fs and msdosfs while there also enable lfs but that's untested
1.93	19-Feb-2012	rmind	Remove COMPAT_SA / KERN_SA. Welcome to 6.99.3! Approved by core@.
1.92	01-Feb-2012	dholland	branches: 1.92.2; Be consistent about whether idtype and objtype codes are signed or unsigned. They are signed. (While unsigned might have been a better choice, it doesn't really matter and the majority of preexisting uses were signed. And consistency is good.)
1.91	01-Feb-2012	dholland	Improve the names of some members of struct quotactl_args. These are effectively function parameter names, but since they need to be described with the same names in the man page the choices do matter. Some.
1.90	01-Feb-2012	dholland	Update compat_netbsd32 for new quotactl.
1.89	31-Jan-2012	matt	Add netbsd32_socklenp_t
1.88	12-Oct-2011	dholland	branches: 1.88.2; 1.88.6; As a precaution, add sys/param.h explicitly to some headers that will no longer get it via sys/ucred.h and don't already include it explicitly. These should in turn be removed when it can be confirmed that it's safe to do so. (Because sys/param.h is full of things that are often tested with #if, it's not in general safe to remove it without checking, as such tests fail silently if the symbol goes missing.)
1.87	30-Jun-2011	wiz	dependant -> dependent
1.86	06-Mar-2011	bouyer	merge the bouyer-quota2 branch. This adds a new on-disk format to store disk quota usage and limits, integrated with ffs metadata. Usage is checked by fsck_ffs (no more quotacheck) and is covered by the WAPBL journal. Enabled with kernel option QUOTA2 (added where QUOTA was enabled in kernel config files), turned on with tunefs(8) on a per-filesystem basis. mount_mfs(8) can also turn quotas on. See http://mail-index.netbsd.org/tech-kern/2011/02/19/msg010025.html for details.
1.85	22-Jan-2011	matt	Add the ability to mount NFS filesystems in COMPAT_NETBSD32 If in the kernel and NFS_ARGS_ONLY, just export struct nfs_args and its flags.
1.84	14-Dec-2009	matt	branches: 1.84.4; 1.84.6; 1.84.8; Merge from matt-nb5-mips64
1.83	12-Dec-2009	njoly	Remove semicolon from NETBSD32TOx_UAP macro definitions.
1.82	16-Mar-2009	njoly	Fix dev_t alignment, by not using the new 64bit value directly but rather a 32bit aligned version (netbsd32_dev_t = netbsd32_uint64). ok by cube@.
1.81	28-Jan-2009	njoly	branches: 1.81.2; Revert the previous packed attribute fix. Instead make netbsd32_time_t of type netbsd32_int64 which provides a 64-bit value with a 32-bit alignment. Suggested by dsl.
1.80	28-Jan-2009	njoly	Make netbsd32_timespec/netbsd32_timeval structures packed. This fix an alignment problem between 64-bit kernel and 32-bit userland versions, which ended in different structure sizes.
1.79	11-Jan-2009	christos	merge christos-time_t
1.78	22-Nov-2008	mrg	branches: 1.78.4; implement netbsd32__sched_setparam(), netbsd32__sched_getparam(), netbsd32__sched_setaffinity() and netbsd32__sched_getaffinity().
1.77	15-Oct-2008	wrstuden	branches: 1.77.2; 1.77.4; Merge wrstuden-revivesa into HEAD.
1.76	29-May-2008	mrg	branches: 1.76.4; remove clause #3 from my license where there are no other copyright holders involved.
1.75	24-May-2008	njoly	Fix netbsd32_ipc_perm and netbsd32_shmid_ds structures to use correct types.
1.74	02-Feb-2008	dsl	branches: 1.74.6; 1.74.8; 1.74.10; 1.74.12; Fix build
1.73	02-Feb-2008	dsl	Use the netbsd32_[u]int64 type for all 64bit items to ensure we have the correct alignment/padding rules. Removed the now-unnecessary #pragma packed for amd64. Should fix the alignment of 'struct netbsd32_kevent' on non-amd64.
1.72	02-Feb-2008	dsl	Change u_intxx_t to uintxx_t and uint to unsigined int etc. Fix indentation.
1.71	25-Dec-2007	perry	Convert many of the uses of __attribute__ to equivalent __packed, __unused and __dead macros from cdefs.h
1.70	20-Dec-2007	dsl	Convert all the system call entry points from: int foo(struct lwp l, void v, register_t retval) to: int foo(struct lwp l, const struct foo_args uap, register_t retval) Fixup compat code to not write into 'uap' and (in some cases) to actually pass a correctly formatted 'uap' structure with the right name to the next routine. A few 'compat' routines that just call standard ones have been deleted. All the 'compat' code compiles (along with the kernels required to test build it). 98% done by automated scripts.
1.69	07-Dec-2007	ad	branches: 1.69.4; Add: _lwp_setname, _lwp_getname, _lwp_ctl.
1.68	29-Sep-2007	dsl	branches: 1.68.4; 1.68.6; Use netbsd32_uint64 instead of fsblkcnt_t and fsfilcnt_t in order to get the correct alignment (4 bytes for i386) for the whole structure.
1.67	16-Sep-2007	dsl	branches: 1.67.2; Define netbsd32_uint64 for 64bit integers with the alignment requirement of the corresponding 32bit architecture. Use it for the 64bit items in netbsd32_statvfs so that the structure doesn't collect 8byte alignment (and 4 bytes of trailing padding). This replaces the 'packed' attribute which wasn't architecture specific and would cause massive overheads accessing every member of sparc64. Should allow the MIPS64 port do DTRT.
1.66	17-Jul-2007	christos	branches: 1.66.6; 1.66.8; include <compat/sys/mount.h> MFSNAMELEN
1.65	30-Jun-2007	dsl	Changes to sompat socket function to avoid the dreaded stackgap.
1.64	03-Jun-2007	dsl	Split netbsd32___semctl14() so that it is callable from compat_10_netbsd32_sys_semsys() (where the one parameter is already in kernel space). Note that the code in compat_10_netbsd32_sys_semsys() has always been wrong, since it called compat_14_sys___semctl() - which would read 64bit values!
1.63	30-Apr-2007	dsl	Rework compat stat() and statvfs() code so that it no longer uses the stackgap.
1.62	18-Mar-2007	dsl	Change all the NETBSD32PTR64(SCARG(uap, xxx))) to SCARG_P32(uap, xxx).
1.61	16-Mar-2007	dsl	remove all the double (and triple) casts used to convert 32bit userspace pointers to and from 64bit kernel pointers. Instead use the defines NETBSD32PTR64(p32) to read a 32bit pointer and (the new) NETBSD32PTR32(p32,p64) to write a 32bit pointer throughout. The 32bit pointer is now a struct to enforce the above. amd64 (with linux emul) and sparc64 will both compile (when the arch stuff goes in soon), and amd64 still runs some i386 binaries.
1.60	04-Mar-2007	christos	branches: 1.60.2; 1.60.4; 1.60.6; fix fallout from caddr_t changes.
1.59	04-Mar-2007	christos	Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.
1.58	19-Feb-2007	cube	Introduce a new member to struct emul, e_startlwp, to be used by sys__lwp_create. It allows using the said syscall under COMPAT_NETBSD32. The libpthread regression tests now pass on amd64 and sparc64.
1.57	09-Feb-2007	ad	branches: 1.57.2; Merge newlock2 to head.
1.56	21-Nov-2006	christos	adjust limits takes struct proc again.
1.55	21-Nov-2006	christos	From Nicolas Joly: > It seems that 32bits programs, running under compat_netbsd32, using > setrlimit force all other programs to have their maximum data size > fixed at 3GB, where native 64bits apps used 8GB previously. I tracked this one to the `netbsd32_adjust_limits()' function (called when creating a new process under compat_netbsd32), where data and stack limits are set without checking for shared `p_limit' structure (p_limit->p_refcnt > 1). This explain the side effect where processes have their limits changed when a compat_netbsd32 (or compat_linux32) program is run. The fix is to use `dosetrlimit()' to ensure the needed copy-on-write behaviour for shared structure.
1.54	13-Jul-2006	martin	branches: 1.54.4; Fix alignement problems for fhandle_t, exposed by gcc4.1. While touching all vptofh/fhtovp functions, get rid of VFS_MAXFIDSIZ, version the getfh(2) syscall and explicitly pass the size available in the filehandle from userland. Discussed on tech-kern, with lots of help from yamt (thanks!).
1.53	31-May-2006	drochner	branches: 1.53.2; support ntp_gettime again compile tested by Havard Eidnes
1.52	11-May-2006	mrg	branches: 1.52.2; add an extra (uintptr_t) cast to NETBSD32TOP.
1.51	29-Mar-2006	cube	Implement the _lwp* and sa_* families of syscalls, using the newly introduced hooks in the native code.

1.47	24-Oct-2005	cube	Move prototypes for siginfo32 to/from siginfo converters at the right place.
1.46	23-Oct-2005	cube	- Split sys_kevent into kevent1 so that it can be used by COMPAT_NETBSD32 code. - To achieve COMPAT_NETBSD32 compatibility, introduce a parameter to kevent1 that points to functions that do the actual copyin/copyout operations. This is similar to what was done in FreeBSD by Paul Saab. - Add the COMPAT_NETBSD32 definitions and hooks.
1.45	07-Oct-2005	chs	branches: 1.45.2; make the previous apply only to x86_64.
1.44	07-Oct-2005	chs	add __attribute__((packed)) to struct netbsd32_stat13. the alignment of 64-bit values is annoying in the x86 world: they require 64-bit alignment in 64-bit mode but only 32-bit alignment in 32-bit mode.
1.43	27-Sep-2005	chs	this needs stuff from compat/sys/siginfo.h now, just include it here.
1.42	27-Sep-2005	chs	make this compile again.
1.41	24-Sep-2005	christos	make the siginfo converters static and comment out the one that is not used.

1.36	23-Jul-2005	cube	Implement the timer_create(2) family of syscalls.
1.35	13-Jul-2005	cube	netbsd32_execve2() doesn't exist anymore.
1.34	04-Jul-2005	cube	branches: 1.34.2; Implement uuidgen(2).
1.33	10-Jun-2005	matt	Rework the coredump code to have no explicit knownledge of how coredump i/o is done. Instead, pass an opaque cookie which is then passed to a new routine, coredump_write, which does the actual i/o. This allows the method of doing i/o to change without affecting any future MD code. Also, make netbsd32_core.c [re]use core_netbsd.c (in a similar manner that core_elf64.c uses core_elf32.c) and eliminate that code duplication. cpu_coredump{,32} is now called twice, first with a NULL iocookie to fill the core structure and a second to actually write md parts of the coredump. All i/o is nolonger random access and is suitable for shipping over a stream.
1.32	02-Jun-2005	drochner	in siginfo conversion functions, declare the source operand as "const"
1.31	26-Mar-2005	fvdl	Fix some things regarding COMPAT_NETBSD32 and limits/VM addresses. * For sparc64 and amd64, define SIZ32 VM constants. Add a new function pointer to struct emul, pointing at a function that will return the default VM map address. The default function is uvm_map_defaultaddr, which just uses the VM_DEFAULT_ADDRESS macro. This gives emulations control over the default map address, and allows things to be mapped at the right address (in 32bit range) for COMPAT_NETBSD32. * Add code to adjust the data and stack limits when a COMPAT_NETBSD32 or COMPAT_SVR4_32 binary is executed. * Don't use USRSTACK in kern_resource.c, use p_vmspace->vm_minsaddr instead (emulations might have set it differently) * Since this changes struct emul, bump kernel version to 3.99.2 Tested on amd64, compile-tested on sparc64.

1.29	17-Jun-2004	cube	branches: 1.29.4; 1.29.6; o Add support for the statvfs family of syscalls (statvfs1, fstatvfs1, fhstatvfs1 and getvfsstat) o Move the statfs family out of netbsd32_fs.c and netbsd32_netbsd.c to netbsd_compat_20.c, compiled with COMPAT_20 Reviewed by christos@.
1.28	20-May-2004	atatat	Tweak sysctl setup functions (the macros, actually) for use in lkms, and tweak lkminit_*.c (where applicable) to call them, and to call sysctl_teardown() when being unloaded. This consists of (1) making setup functions not be static when being compiled as lkms (change to sys/sysctl.h), (2) making prototypes visible for the various setup functions in header files (changes to various header files), and (3) making simple "load" and "unload" functions in the actual lkminit stuff. linux_sysctl.c also needs its root exposed (ie, made not static) for this (when built as an lkm).
1.27	21-Jan-2004	mrg	branches: 1.27.2; delete ktrsyscall32() prototype
1.26	15-Jan-2004	mrg	add a copy of the ktrsyscall() entry point for 32 bit emulated calls. the main purpose of this function is to adjust the "argsize" value of the ktrace syscall record, otherwise userland will see N/2 (rounded down) arguments instead of N.
1.25	13-Oct-2003	fvdl	Implement 32bit get/setcontext entry points.

1.23	27-Nov-2002	atatat	Complete the rename: s/sa_/<compat>_sa_/g Also tweak the darwin siginfo stuff to avoid the same type of collision.
1.22	23-Oct-2002	scw	In preparation for COMPAT_NETBSD32 on SH-5: - The MD netbsd32_machdep.h header now defines the 32-bit pointer type instead of using u_int32_t everywhere, - The MD netbsd32_machdep.h header now defines a macro (at least on current implementations) which converts a 32-bit pointer to its 64-bit equivalent, - Change the MI code to utilise the above two items in all the right places, - Implement netbsd32___sigaction_sigtramp(). Tested on Sparc64 by Matt Green.
1.21	08-Dec-2001	thorpej	Make the coredump routine exec-format/emulation specific. Split out traditional NetBSD coredump routines into core_netbsd.c and netbsd32_core.c (for COMPAT_NETBSD32).

1.27.2.1	23-May-2004	tron	Pull up revision 1.28 (requested by atatat in ticket #374): Tweak sysctl setup functions (the macros, actually) for use in lkms, and tweak lkminit_*.c (where applicable) to call them, and to call sysctl_teardown() when being unloaded. This consists of (1) making setup functions not be static when being compiled as lkms (change to sys/sysctl.h), (2) making prototypes visible for the various setup functions in header files (changes to various header files), and (3) making simple "load" and "unload" functions in the actual lkminit stuff. linux_sysctl.c also needs its root exposed (ie, made not static) for this (when built as an lkm).

Add a new function pointer to struct emul, pointing at a function that will return the default VM map address. The default function is uvm_map_defaultaddr, which just uses the VM_DEFAULT_ADDRESS macro. This gives emulations control over the default map address, and allows things to be mapped at the right address (in 32bit range) for COMPAT_NETBSD32. * Add code to adjust the data and stack limits when a COMPAT_NETBSD32 or COMPAT_SVR4_32 binary is executed. * Don't use USRSTACK in kern_resource.c, use p_vmspace->vm_minsaddr instead (emulations might have set it differently) * Since this changes struct emul, bump kernel version to 3.99.2 Tested on amd64, compile-tested on sparc64.

1.74.12.3	23-Jun-2008	wrstuden	Sync w/ -current. 34 merge conflicts to follow.
1.74.12.2	14-May-2008	wrstuden	Per discussion with ad, remove most of the #include <sys/sa.h> lines as they were including sa.h just for the type(s) needed for syscallargs.h. Instead, create a new file, sys/satypes.h, which contains just the types needed for syscallargs.h. Yes, there's only one now, but that may change and it's probably more likely to change if it'd be difficult to handle. :-) Per discussion with matt at n dot o, add an include of satypes.h to sigtypes.h. Upcall handlers are kinda signal handlers, and signalling is the header file that's already included for syscallargs.h that closest matches SA. This shaves about 3000 lines off of the diff of the branch relative to the base. That also represents about 18% of the total before this checkin. I think this reduction is very good thing.
1.74.12.1	10-May-2008	wrstuden	Initial checkin of re-adding SA. Everything except kern_sa.c compiles in GENERIC for i386. This is still a work-in-progress, but this checkin covers most of the mechanical work (changing signalling to be able to accomidate SA's process-wide signalling and re-adding includes of sys/sa.h and savar.h). Subsequent changes will be much more interesting. Also, kern_sa.c has received partial cleanup. There's still more to do, though.

Remove the filesystem tracing feature This is a legacy interface from 4.4BSD, and it was introduced to overcome shortcomings of ptrace(2) at that time, which are no longer relevant (performance). Today /proc/#/ctl offers a narrow subset of ptrace(2) commands and is not applicable for modern applications use beyond simplistic tracing scenarios. This removal will simplify kernel internals. Users will still be able to use all the other /proc files. This change won't affect other procfs files neither Linux compat features within mount_procfs(8). /proc/#/ctl isn't available on Linux. Remove: - /proc/#/ctl from mount_procfs(8) - P_FSTRACE note from the documentation of ps(1) - /proc/#/ctl and filesystem tracing documentation from mount_procfs(8) - KAUTH_REQ_PROCESS_PROCFS_CTL documentation from kauth(9) - source code file miscfs/procfs/procfs_ctl.c - PFSctl and procfs_doctl() from sys/miscfs/procfs/procfs.h - KAUTH_REQ_PROCESS_PROCFS_CTL from sys/sys/kauth.h - PSL_FSTRACE (0x00010000) from sys/sys/proc.h - P_FSTRACE (0x00010000) from sys/sys/sysctl.h Reduce code complexity after removal of this functionality. Update TODO.ptrace accordingly: remove two entries about /proc tracing. Do not keep legacy notes as comments in the headers about removed PSL_FSTRACE / P_FSTRACE, as this interface had little number of users (close or equal to zero). Proposed on tech-kern@. All filesystem tracing utility users are encouraged to switch to ptrace(2). Sponsored by <The NetBSD Foundation> untangle the mess: - factor out common code - break each ptrace subcall to its own sub-function .. more to come ... - reduce ifdef ugliness by moving it up top. - factor out PT_IO and make PT_{READ,WRITE}_{I,D} use it - factor out PT_DUMPCORE - factor out sendsig code .. more to come ... handle siginfo requests for ptrace32 ptrace: Partially undo PT_{READ,WRITE}_{I,D} and unbreak these commands The refactored code did not work and was generating EFAULT. Sponsored by <The NetBSD Foundation> Merge the code back; the problem was that since we are reading/writing to a kernel address for PT_{READ,WRITE}_{I,D} we need the kernel vmspace. provide separate read and write functions to accomodate register functions that need a size argument. don't ignore error from copyout_piod Use the proper process (the tracee) to get information about lwps and registers and the tracer for vmspace. Add new sysctl(3) entry: security.models.extensions.user_set_dbregs Model this new sysctl(3) entry after "user_set_cpu_affinity" in the same level of sysctl(3) switches. Allow to read unconditionally Debug Registers (no change here). This is convenient as even if a user of a debugger does not use hardware assisted watchpoints/breakpoints, a debugger can still prompt these values to store in an internal cache with context of registers. Reading them should have no security concerns. Add a paranoid MI switch that prohibits by default setting these registers by a regular user (non-superuser). Make this switch disabled by default. There are enough reserved bits out there to allow using them unconditionally on hardened hosts. Features shipped with Debug Registers are optional features in debuggers. There is no reduction in elementary functionality. Reviewed by <christos> Sponsored by <The NetBSD Foundation>

XXX: still leaves some netbsd32 code in rf_netbsdkintf.c, that should be moved into some hooks, but first the configuration setup needs to be moved into a common function the netbsd32 code can call into, vs living in the switch case itself.

Now all nodes are registered with the tree, and nodes can be added (or removed) easily, and I/O to and from the tree is handled generically. Since the nodes are registered with the tree, the mapping from name to number (and back again) can now be discovered, instead of having to be hard coded. Adding new nodes to the tree is likewise much simpler -- the new infrastructure handles almost all the work for simple types, and just about anything else can be done with a small helper function. All existing nodes are where they were before (numerically speaking), so all existing consumers of sysctl information should notice no difference. PS - I'm sorry, but there's a distinct lack of documentation at the moment. I'm working on sysctl(3/8/9) right now, and I promise to watch out for buses.

1.17.12.2	14-May-2008	wrstuden	Per discussion with ad, remove most of the #include <sys/sa.h> lines as they were including sa.h just for the type(s) needed for syscallargs.h. Instead, create a new file, sys/satypes.h, which contains just the types needed for syscallargs.h. Yes, there's only one now, but that may change and it's probably more likely to change if it'd be difficult to handle. :-) Per discussion with matt at n dot o, add an include of satypes.h to sigtypes.h. Upcall handlers are kinda signal handlers, and signalling is the header file that's already included for syscallargs.h that closest matches SA. This shaves about 3000 lines off of the diff of the branch relative to the base. That also represents about 18% of the total before this checkin. I think this reduction is very good thing.
1.17.12.1	10-May-2008	wrstuden	Initial checkin of re-adding SA. Everything except kern_sa.c compiles in GENERIC for i386. This is still a work-in-progress, but this checkin covers most of the mechanical work (changing signalling to be able to accomidate SA's process-wide signalling and re-adding includes of sys/sa.h and savar.h). Subsequent changes will be much more interesting. Also, kern_sa.c has received partial cleanup. There's still more to do, though.

Note that the code in compat_10_netbsd32_sys_semsys() has always been wrong, since it called compat_14_sys___semctl() - which would read 64bit values!
1.19	16-Mar-2007	dsl	remove all the double (and triple) casts used to convert 32bit userspace pointers to and from 64bit kernel pointers. Instead use the defines NETBSD32PTR64(p32) to read a 32bit pointer and (the new) NETBSD32PTR32(p32,p64) to write a 32bit pointer throughout. The 32bit pointer is now a struct to enforce the above. amd64 (with linux emul) and sparc64 will both compile (when the arch stuff goes in soon), and amd64 still runs some i386 binaries.

1.14	23-Oct-2002	scw	In preparation for COMPAT_NETBSD32 on SH-5: - The MD netbsd32_machdep.h header now defines the 32-bit pointer type instead of using u_int32_t everywhere, - The MD netbsd32_machdep.h header now defines a macro (at least on current implementations) which converts a 32-bit pointer to its 64-bit equivalent, - Change the MI code to utilise the above two items in all the right places, - Implement netbsd32___sigaction_sigtramp(). Tested on Sparc64 by Matt Green.
1.13	29-Apr-2002	mrg	build the netbsd32_compat* objects into libcompat.a, so they are available to emulations not just netbsd itself. rename the compat_10 functions to match everything else. fixes a problem reported by julian coleman.

Instead, create a new file, sys/satypes.h, which contains just the types needed for syscallargs.h. Yes, there's only one now, but that may change and it's probably more likely to change if it'd be difficult to handle. :-) Per discussion with matt at n dot o, add an include of satypes.h to sigtypes.h. Upcall handlers are kinda signal handlers, and signalling is the header file that's already included for syscallargs.h that closest matches SA. This shaves about 3000 lines off of the diff of the branch relative to the base. That also represents about 18% of the total before this checkin. I think this reduction is very good thing.

Subsequent changes will be much more interesting. Also, kern_sa.c has received partial cleanup. There's still more to do, though.

A few 'compat' routines that just call standard ones have been deleted. All the 'compat' code compiles (along with the kernels required to test build it). 98% done by automated scripts.

1.26	22-Apr-2007	dsl	Change the way that emulations locate files within the emulation root to avoid having to allocate space in the 'stackgap' - which is very LWP unfriendly. The additional code for non-emulation namei() is trivial, the reduction for the emulations is massive. The vnode for a processes emulation root is saved in the cwdi structure during process exec. If the emulation root the TRYEMULROOT flag are set, namei() will do an initial search for absolute pathnames in the emulation root, if that fails it will retry from the normal root. ".." at the emulation root will always go to the real root, even in the middle of paths and when expanding symlinks. Absolute symlinks found using absolute paths in the emulation root will be relative to the emulation root (so /usr/lib/xxx.so -> /lib/xxx.so links inside the emulation root don't need changing). If the root of the emulation would be returned (for an emulation lookup), then the real root is returned instead (matching the behaviour of emul_lookup, but being a cheap comparison here) so that programs that scan "../.." looking for the root dircetory don't loop forever. The target for symbolic links is no longer mangled (it used to get the CHECK_ALT_xxx() treatment, so could get /emul/xxx prepended). CHECK_ALT_xxx() are no more. Most of the change is deleting them, and adding TRYEMULROOT to the flags to NDINIT(). A lot of the emulation system call stubs could now be deleted.
1.25	18-Mar-2007	dsl	Change all the NETBSD32PTR64(SCARG(uap, xxx))) to SCARG_P32(uap, xxx).
1.24	16-Mar-2007	dsl	remove all the double (and triple) casts used to convert 32bit userspace pointers to and from 64bit kernel pointers. Instead use the defines NETBSD32PTR64(p32) to read a 32bit pointer and (the new) NETBSD32PTR32(p32,p64) to write a 32bit pointer throughout. The 32bit pointer is now a struct to enforce the above. amd64 (with linux emul) and sparc64 will both compile (when the arch stuff goes in soon), and amd64 still runs some i386 binaries.

1.17	28-Jun-2003	darrenr	Pass lwp pointers throughtout the kernel, as required, so that the lwpid can be inserted into ktrace records.

1.33.36.9	03-Oct-2018	pgoyette	Normalize the required lists. Each compat_netbsd32_xx needs the non-32bit module of the same version _and_ the 32-bit module for the next higher version.
1.33.36.8	03-Oct-2018	pgoyette	Make sure that each version-specific compat_netbsd32_xx module depends on all higher-version-specific modules, similar to the non-32bit compat_xx modules.
1.33.36.7	11-Sep-2018	pgoyette	Put the ``extern struct emul'' into the netbsd32_netbsd.h header so it doesn't have to be separately declared in each source file. Thanks mrg@
1.33.36.6	11-Sep-2018	pgoyette	Also need to declare the emul_netbsd32 !
1.33.36.5	11-Sep-2018	pgoyette	Install the syscalls into the netbsd32 table, not the default/native table.
1.33.36.4	11-Sep-2018	pgoyette	Use netbsd32 syscall names in the establish/disestablish tables
1.33.36.3	11-Sep-2018	pgoyette	Regen syscall files and fix includes for syscallvar.h

1.28	19-Jan-2021	simonb	KNF consistency: No parentheses are needed around the return value.
1.27	27-Jan-2019	pgoyette	branches: 1.27.12; Merge the [pgoyette-compat] branch
1.26	24-Jan-2014	christos	branches: 1.26.28; 1.26.30; need to lock the process.
1.25	29-May-2008	mrg	branches: 1.25.12; 1.25.34; 1.25.44; 1.25.50; remove clause #3 from my license where there are no other copyright holders involved.
1.24	20-Dec-2007	dsl	branches: 1.24.6; 1.24.8; 1.24.10; 1.24.12; Convert all the system call entry points from: int foo(struct lwp l, void v, register_t retval) to: int foo(struct lwp l, const struct foo_args uap, register_t retval) Fixup compat code to not write into 'uap' and (in some cases) to actually pass a correctly formatted 'uap' structure with the right name to the next routine. A few 'compat' routines that just call standard ones have been deleted. All the 'compat' code compiles (along with the kernels required to test build it). 98% done by automated scripts.
1.23	08-Dec-2007	dsl	branches: 1.23.4; ANSIfy most of the function definitions in sys/compat (but not ndis). All by the magic of sed ...
1.22	16-Jun-2007	dsl	branches: 1.22.6; 1.22.8; 1.22.16; Modify the (recently added) compat_sigaltstack() #define to take the values of the SS_ONSTACK and SS_DISABLE constants. Use it to shorten the source files when this action is replicated. Actually, given the monstrous complexity of sigaltstack1() there is probably a much better way to do this...
1.21	03-Jun-2007	dsl	Add a #define that expands to the compat wrapper for sigaltstack1(). Use it for the netbsd32_compat_13.c version of the code.
1.20	03-Jun-2007	dsl	Calling sigaltstack1() directly is so much easier than going via compat_13_sys_sigaltstack().
1.19	18-Mar-2007	dsl	Change all the NETBSD32PTR64(SCARG(uap, xxx))) to SCARG_P32(uap, xxx).
1.18	16-Mar-2007	dsl	remove all the double (and triple) casts used to convert 32bit userspace pointers to and from 64bit kernel pointers. Instead use the defines NETBSD32PTR64(p32) to read a 32bit pointer and (the new) NETBSD32PTR32(p32,p64) to write a 32bit pointer throughout. The 32bit pointer is now a struct to enforce the above. amd64 (with linux emul) and sparc64 will both compile (when the arch stuff goes in soon), and amd64 still runs some i386 binaries.
1.17	04-Mar-2007	christos	branches: 1.17.2; 1.17.4; 1.17.6; Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.
1.16	09-Feb-2007	ad	branches: 1.16.2; Merge newlock2 to head.
1.15	11-Dec-2005	christos	branches: 1.15.20; merge ktrace-lwp.
1.14	13-Sep-2005	christos	make this compile again.
1.13	18-Jan-2003	thorpej	branches: 1.13.2; 1.13.18; Merge the nathanw_sa branch.
1.12	23-Oct-2002	scw	In preparation for COMPAT_NETBSD32 on SH-5: - The MD netbsd32_machdep.h header now defines the 32-bit pointer type instead of using u_int32_t everywhere, - The MD netbsd32_machdep.h header now defines a macro (at least on current implementations) which converts a 32-bit pointer to its 64-bit equivalent, - Change the MI code to utilise the above two items in all the right places, - Implement netbsd32___sigaction_sigtramp(). Tested on Sparc64 by Matt Green.
1.11	16-Mar-2002	christos	make the stackgap_{init,alloc} functions MP friendly (i.e. pass struct proc * in, instead of using curproc). While there add an optional size argument to stackgap_init.
1.10	13-Nov-2001	lukem	add RCSIDs (including regeneration of files as appropriate)
1.9	25-Aug-2001	mrg	update copyright notices.
1.8	07-Feb-2001	mrg	branches: 1.8.2; 1.8.4; fix the glaring errors in compat_13_netbsd32_sigaltstack13
1.7	09-Jul-2000	mrg	- massive warning fix fest. - fix pread/pwrite return values (plus some other syscalls that looked similarly broken). - prototypes and clean up for netbsd32_ioctl.c now getpw*() works under compat32!
1.6	30-Mar-2000	augustss	Kill register declarations.
1.5	30-Dec-1999	eeh	Update to 32-bit compatibility routines.
1.4	11-Oct-1999	eeh	branches: 1.4.2; Add netbsd32_compat_14.c Rename everything from compat_netbsd32 -> netbsd32 so we don't have silly names like compat_14_compat_netbsd32_sys_shmctl().
1.3	25-Mar-1999	mrg	branches: 1.3.8; move sparc32 to netbsd32; split out MD part (signal handling) (mostly via repository copy, rename and perl -pi :-)
1.2	26-Aug-1998	mrg	use right syscalls
1.1	26-Aug-1998	mrg	add a 32-bit compatibility module for the sparc64 port, so it can run NetBSD/sparc binaries with a LP64 kernel.

1.24.12.2	14-May-2008	wrstuden	Per discussion with ad, remove most of the #include <sys/sa.h> lines as they were including sa.h just for the type(s) needed for syscallargs.h. Instead, create a new file, sys/satypes.h, which contains just the types needed for syscallargs.h. Yes, there's only one now, but that may change and it's probably more likely to change if it'd be difficult to handle. :-) Per discussion with matt at n dot o, add an include of satypes.h to sigtypes.h. Upcall handlers are kinda signal handlers, and signalling is the header file that's already included for syscallargs.h that closest matches SA. This shaves about 3000 lines off of the diff of the branch relative to the base. That also represents about 18% of the total before this checkin. I think this reduction is very good thing.
1.24.12.1	10-May-2008	wrstuden	Initial checkin of re-adding SA. Everything except kern_sa.c compiles in GENERIC for i386. This is still a work-in-progress, but this checkin covers most of the mechanical work (changing signalling to be able to accomidate SA's process-wide signalling and re-adding includes of sys/sa.h and savar.h). Subsequent changes will be much more interesting. Also, kern_sa.c has received partial cleanup. There's still more to do, though.

1.26.28.9	03-Oct-2018	pgoyette	Normalize the required lists. Each compat_netbsd32_xx needs the non-32bit module of the same version _and_ the 32-bit module for the next higher version.

1.29	21-Feb-2019	mrg	fix naming errors in previous. (this file is no longer compiled, but this fix makes the pull up more obvious, before deleting this file.)
1.28	21-Feb-2019	mrg	for sysv ipc stat operations, explicitly copy the exported parts instead of the whole ds structure. besides triggering a recently added assert in netbsd32, this stops exposing kernel addresses. copy the mode clamping to 0777 from sem to shm and msg. while here, make sure that the compat callers to sysv_ipc clear the contents of the compat structure before setting the result members to ensure padding bytes are cleared. don't set/copy _sem_base, _msg_first, _msg_last or _shm_internal. even if used, which seems very dodgy, they leak KVAs as well. possibly this may affect linux binaries, in particular, the comments around _shm_internal ("XXX Oh well.") may mean apps rely upon these but hopefully not -- the comments date back to rev 1.1 in 1995. the _key, _seq and _msg_cbytes members are exported as before as i found multiple consumers of these (no less than ipcs(1), and they appear to be useful for debugging and more. XXX: the naming of compat functions have too many styles. there are at least 3 different ones changed here.
1.27	27-Dec-2018	maxv	Fix kernel info leaks. + Possible info leak: [len=80, leaked=10] \| #0 0xffffffff80bad7a7 in kleak_copyout \| #1 0xffffffff8048e71b in netbsd32___msgctl50 \| #2 0xffffffff8022fb5b in netbsd32_syscall \| #3 0xffffffff802096dd in handle_syscall

1.23	03-Dec-2015	pgoyette	Missed these. Only include the compat_14 sys calls if this being compiled as part of the compat_netbsd32_sysvipc module.
1.22	03-Dec-2015	pgoyette	Split out the SYSV IPC stuff into its own compat_netbsd32_sysvipc module. Adjust dependencies as needed.
1.21	20-Dec-2007	dsl	branches: 1.21.12; 1.21.56; 1.21.74; 1.21.76; 1.21.78; 1.21.82; Convert all the system call entry points from: int foo(struct lwp l, void v, register_t retval) to: int foo(struct lwp l, const struct foo_args uap, register_t retval) Fixup compat code to not write into 'uap' and (in some cases) to actually pass a correctly formatted 'uap' structure with the right name to the next routine. A few 'compat' routines that just call standard ones have been deleted. All the 'compat' code compiles (along with the kernels required to test build it). 98% done by automated scripts.
1.20	08-Dec-2007	dsl	branches: 1.20.4; ANSIfy most of the function definitions in sys/compat (but not ndis). All by the magic of sed ...
1.19	20-Mar-2007	cube	branches: 1.19.8; 1.19.10; 1.19.18; More SCARG_P32 fallout.
1.18	20-Mar-2007	cube	Fix typo. Reported by martin.
1.17	18-Mar-2007	dsl	Change all the NETBSD32PTR64(SCARG(uap, xxx))) to SCARG_P32(uap, xxx).
1.16	16-Mar-2007	dsl	remove all the double (and triple) casts used to convert 32bit userspace pointers to and from 64bit kernel pointers. Instead use the defines NETBSD32PTR64(p32) to read a 32bit pointer and (the new) NETBSD32PTR32(p32,p64) to write a 32bit pointer throughout. The 32bit pointer is now a struct to enforce the above. amd64 (with linux emul) and sparc64 will both compile (when the arch stuff goes in soon), and amd64 still runs some i386 binaries.
1.15	04-Mar-2007	christos	branches: 1.15.2; 1.15.4; 1.15.6; Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.

1.9	18-Jan-2003	thorpej	branches: 1.9.2; 1.9.10; 1.9.12; Merge the nathanw_sa branch.
1.8	23-Oct-2002	scw	In preparation for COMPAT_NETBSD32 on SH-5: - The MD netbsd32_machdep.h header now defines the 32-bit pointer type instead of using u_int32_t everywhere, - The MD netbsd32_machdep.h header now defines a macro (at least on current implementations) which converts a 32-bit pointer to its 64-bit equivalent, - Change the MI code to utilise the above two items in all the right places, - Implement netbsd32___sigaction_sigtramp(). Tested on Sparc64 by Matt Green.
1.7	15-Nov-2001	lukem	don't need <sys/types.h> when including <sys/param.h>
1.6	13-Nov-2001	lukem	add RCSIDs (including regeneration of files as appropriate)
1.5	30-Nov-2000	jdolecek	branches: 1.5.2; 1.5.4; only define SYSVMSG, SYSVSEM, SYSVSHM if it's not defined already
1.4	18-Nov-2000	mrg	kill gcc warnings.
1.3	09-Jul-2000	mrg	- massive warning fix fest. - fix pread/pwrite return values (plus some other syscalls that looked similarly broken). - prototypes and clean up for netbsd32_ioctl.c now getpw*() works under compat32!
1.2	30-Dec-1999	eeh	Update to 32-bit compatibility routines.
1.1	11-Oct-1999	eeh	branches: 1.1.2; 1.1.8; Add netbsd32_compat_14.c Rename everything from compat_netbsd32 -> netbsd32 so we don't have silly names like compat_14_compat_netbsd32_sys_shmctl().

1.21.56.1	03-Dec-2017	jdolecek	update from HEAD
1.21.12.2	14-May-2008	wrstuden	Per discussion with ad, remove most of the #include <sys/sa.h> lines as they were including sa.h just for the type(s) needed for syscallargs.h. Instead, create a new file, sys/satypes.h, which contains just the types needed for syscallargs.h. Yes, there's only one now, but that may change and it's probably more likely to change if it'd be difficult to handle. :-) Per discussion with matt at n dot o, add an include of satypes.h to sigtypes.h. Upcall handlers are kinda signal handlers, and signalling is the header file that's already included for syscallargs.h that closest matches SA. This shaves about 3000 lines off of the diff of the branch relative to the base. That also represents about 18% of the total before this checkin. I think this reduction is very good thing.
1.21.12.1	10-May-2008	wrstuden	Initial checkin of re-adding SA. Everything except kern_sa.c compiles in GENERIC for i386. This is still a work-in-progress, but this checkin covers most of the mechanical work (changing signalling to be able to accomidate SA's process-wide signalling and re-adding includes of sys/sa.h and savar.h). Subsequent changes will be much more interesting. Also, kern_sa.c has received partial cleanup. There's still more to do, though.

1.24	06-May-2008	ad	branches: 1.24.2; PR kern/38141 lookup/vfs_busy acquire rwlock recursively Simplify the mount locking. Remove all the crud to deal with recursion on the mount lock, and crud to deal with unmount as another weirdo lock. Hopefully this will once and for all fix the deadlocks with this. With this commit there are two locks on each mount: - krwlock_t mnt_unmounting. This is used to prevent unmount across critical sections like getnewvnode(). It's only ever read locked with rw_tryenter(), and is only ever write locked in dounmount(). A write hold can't be taken on this lock if the current LWP could hold a vnode lock. - kmutex_t mnt_updating. This is taken by threads updating the mount, for example when going r/o -> r/w, and is only present to serialize updates. In order to take this lock, a read hold must first be taken on mnt_unmounting, and the two need to be held across the operation. One effect of this change: previously if an unmount failed, we would make a half hearted attempt to back out of it gracefully, but that was unlikely to work in a lot of cases. Now while an unmount that will be aborted is in progress, new file operations within the mount will fail instead of being delayed. That is unlikely to be a problem though, because if the admin requests unmount of a file system then s(he) has made a decision to deny access to the resource.
1.23	30-Apr-2008	ad	PR kern/38135 vfs_busy/vfs_trybusy confusion The previous fix worked, but it opened a window where mounts could have disappeared from mountlist while the caller was traversing it using vfs_trybusy(). Fix that.

1.13	17-Jul-2007	christos	branches: 1.13.2; kill silly constants.
1.12	22-Apr-2007	dsl	Change the way that emulations locate files within the emulation root to avoid having to allocate space in the 'stackgap' - which is very LWP unfriendly. The additional code for non-emulation namei() is trivial, the reduction for the emulations is massive. The vnode for a processes emulation root is saved in the cwdi structure during process exec. If the emulation root the TRYEMULROOT flag are set, namei() will do an initial search for absolute pathnames in the emulation root, if that fails it will retry from the normal root. ".." at the emulation root will always go to the real root, even in the middle of paths and when expanding symlinks. Absolute symlinks found using absolute paths in the emulation root will be relative to the emulation root (so /usr/lib/xxx.so -> /lib/xxx.so links inside the emulation root don't need changing). If the root of the emulation would be returned (for an emulation lookup), then the real root is returned instead (matching the behaviour of emul_lookup, but being a cheap comparison here) so that programs that scan "../.." looking for the root dircetory don't loop forever. The target for symbolic links is no longer mangled (it used to get the CHECK_ALT_xxx() treatment, so could get /emul/xxx prepended). CHECK_ALT_xxx() are no more. Most of the change is deleting them, and adding TRYEMULROOT to the flags to NDINIT(). A lot of the emulation system call stubs could now be deleted.

1.24.2.2	14-May-2008	wrstuden	Per discussion with ad, remove most of the #include <sys/sa.h> lines as they were including sa.h just for the type(s) needed for syscallargs.h. Instead, create a new file, sys/satypes.h, which contains just the types needed for syscallargs.h. Yes, there's only one now, but that may change and it's probably more likely to change if it'd be difficult to handle. :-) Per discussion with matt at n dot o, add an include of satypes.h to sigtypes.h. Upcall handlers are kinda signal handlers, and signalling is the header file that's already included for syscallargs.h that closest matches SA. This shaves about 3000 lines off of the diff of the branch relative to the base. That also represents about 18% of the total before this checkin. I think this reduction is very good thing.
1.24.2.1	10-May-2008	wrstuden	Initial checkin of re-adding SA. Everything except kern_sa.c compiles in GENERIC for i386. This is still a work-in-progress, but this checkin covers most of the mechanical work (changing signalling to be able to accomidate SA's process-wide signalling and re-adding includes of sys/sa.h and savar.h). Subsequent changes will be much more interesting. Also, kern_sa.c has received partial cleanup. There's still more to do, though.

This leads to a user-triggerable stack overflow. On my test build at least, by luck, the compiler orders the variables in a way that the overflow hits only local structures which haven't yet been initialized and used, so the overflow is harmless. Very easily seeable with kASan - just invoke the syscall from a 32bit binary. Fix three stack info leaks, found by kMSan when just invoking all syscalls with a zero page as argument. MSan: Uninitialized Stack Memory In copyout() At Offset 0, Variable 'sb32' From compat_20_netbsd32_getfsstat() MSan: Uninitialized Stack Memory In copyout() At Offset 12, Variable 'oss' From compat_43_sys_sigstack() MSan: Uninitialized Stack Memory In copyout() At Offset 0, Variable 'sb' From compat_50_netbsd32___fhstat40()

1.33	27-Jan-2019	pgoyette	branches: 1.33.6; Merge the [pgoyette-compat] branch
1.32	03-Sep-2018	riastradh	Rename min/max -> uimin/uimax for better honesty. These functions are defined on unsigned int. The generic name min/max should not silently truncate to 32 bits on 64-bit systems. This is purely a name change -- no functional change intended. HOWEVER! Some subsystems have #define min(a, b) ((a) < (b) ? (a) : (b)) #define max(a, b) ((a) > (b) ? (a) : (b)) even though our standard name for that is MIN/MAX. Although these may invite multiple evaluation bugs, these do _not_ cause integer truncation. To avoid `fixing' these cases, I first changed the name in libkern, and then compile-tested every file where min/max occurred in order to confirm that it failed -- and thus confirm that nothing shadowed min/max -- before changing it. I have left a handful of bootloaders that are too annoying to compile-test, and some dead code: cobalt ews4800mips hp300 hppa ia64 luna68k vax acorn32/if_ie.c (not included in any kernels) macppc/if_gm.c (superseded by gem(4)) It should be easy to fix the fallout once identified -- this way of doing things fails safe, and the goal here, after all, is to _avoid_ silent integer truncations, not introduce them. Maybe one day we can reintroduce min/max as type-generic things that never silently truncate. But we should avoid doing that for a while, so that existing code has a chance to be detected by the compiler for conversion to uimin/uimax without changing the semantics until we can properly audit it all. (Who knows, maybe in some cases integer truncation is actually intended!)
1.31	05-Dec-2014	maxv	branches: 1.31.16; 1.31.18; User-triggerable kmem_alloc(0). Ok martin@ christos@ User

Also, same fix in osf1_sys_sendmsg_xopen(). - Fix attempt to free non-allocated memory in error path in netbsd32___getfh30(). - Plug a memory leak in compat_43_netbsd32_orecvmsg().

1.23	20-Dec-2007	dsl	branches: 1.23.6; Convert all the system call entry points from: int foo(struct lwp l, void v, register_t retval) to: int foo(struct lwp l, const struct foo_args uap, register_t retval) Fixup compat code to not write into 'uap' and (in some cases) to actually pass a correctly formatted 'uap' structure with the right name to the next routine. A few 'compat' routines that just call standard ones have been deleted. All the 'compat' code compiles (along with the kernels required to test build it). 98% done by automated scripts.
1.22	08-Dec-2007	dsl	branches: 1.22.4; ANSIfy most of the function definitions in sys/compat (but not ndis). All by the magic of sed ...
1.21	30-Apr-2007	dsl	branches: 1.21.6; 1.21.8; 1.21.16; Split the statvfs functions so that the 'work' is done to a kernel buffer which can either be copied directly to userspace, or converted then copied. Saves replicating a lot of code in the compat functions (esp. for getvfsstat) at a cast of an extra function call in the non-emulated case - which is unlikely to be measurable given the other costs of the actions involved (even on vax). Remove dofhstat() and dofhstatvfs() (and the last caller). Remove some redundant stackgap_init() calls.
1.20	22-Apr-2007	dsl	Change the way that emulations locate files within the emulation root to avoid having to allocate space in the 'stackgap' - which is very LWP unfriendly. The additional code for non-emulation namei() is trivial, the reduction for the emulations is massive. The vnode for a processes emulation root is saved in the cwdi structure during process exec. If the emulation root the TRYEMULROOT flag are set, namei() will do an initial search for absolute pathnames in the emulation root, if that fails it will retry from the normal root. ".." at the emulation root will always go to the real root, even in the middle of paths and when expanding symlinks. Absolute symlinks found using absolute paths in the emulation root will be relative to the emulation root (so /usr/lib/xxx.so -> /lib/xxx.so links inside the emulation root don't need changing). If the root of the emulation would be returned (for an emulation lookup), then the real root is returned instead (matching the behaviour of emul_lookup, but being a cheap comparison here) so that programs that scan "../.." looking for the root dircetory don't loop forever. The target for symbolic links is no longer mangled (it used to get the CHECK_ALT_xxx() treatment, so could get /emul/xxx prepended). CHECK_ALT_xxx() are no more. Most of the change is deleting them, and adding TRYEMULROOT to the flags to NDINIT(). A lot of the emulation system call stubs could now be deleted.
1.19	18-Mar-2007	dsl	Change all the NETBSD32PTR64(SCARG(uap, xxx))) to SCARG_P32(uap, xxx).
1.18	10-Mar-2007	dsl	branches: 1.18.2; 1.18.4; Update all the compat stuff to not use the 'stackgap' for processing sys_stat() and friends, instead use do_sys_stat() and do_sys_fstat() that write the answer into a kernel buffer (on stack) that can be converted to the correct form and written the userspace. I've test compiled a few kernels, and tested i386 netbsd1.6 ls. Given I think I've fixed some bugs, it might be 50-50 with new ones.
1.17	04-Mar-2007	christos	branches: 1.17.2; Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.
1.16	09-Feb-2007	ad	branches: 1.16.2; Merge newlock2 to head.
1.15	14-Nov-2006	elad	Clean some KAUTH_GENERIC_ISSUSER usage in compat code.
1.14	09-Nov-2006	cube	- Make better use of COMPAT_XX type in syscalls.master - Remove useless (thanks to COMPAT_XX behaviour) #ifdefs in syscalls.master - Make netbsd32_compat_43.c compiled per COMPAT_LINUX32 because the latter needs stuff from it. Fixes Perry's PR#34951.
1.13	04-Aug-2006	yamt	branches: 1.13.4; 1.13.6; some filehandle syscall related changes. - remove the support of variable-sized filehandle from compat version of syscalls. (strictly speaking, it breaks abi. i don't think it's a problem because this feature is short-lived and there are no affected in-tree filesystems.) - unify vfs_copyinfh_alloc and vfs_copyinfh_alloc_size. - vfs_copyinfh_alloc_size: check fhsize strictly. - reduce code duplication between compat and current syscalls.
1.12	31-Jul-2006	martin	Make filehandles opaque to userland
1.11	23-Jul-2006	ad	Use the LWP cached credentials where sane.
1.10	13-Jul-2006	pavel	do not protect the getfh syscall by #if defined(NFS) \|\| defined(NFSSERVER). The native syscall also isn't.
1.9	13-Jul-2006	martin	Fix alignement problems for fhandle_t, exposed by gcc4.1. While touching all vptofh/fhtovp functions, get rid of VFS_MAXFIDSIZ, version the getfh(2) syscall and explicitly pass the size available in the filehandle from userland. Discussed on tech-kern, with lots of help from yamt (thanks!).

1.6	05-May-2006	cube	Move fhstat as sys___fhstat30 in netbsd32_fs.c because it doesn't belong to netbsd32_netbsd.c (which incidentally means it had been broken for a while I guess). Add compat_30 version.
1.5	07-Mar-2006	thorpej	branches: 1.5.2; 1.5.4; Clean up fallout proc_is_traced_p() change: - proc_is_traced_p() -> trace_is_enabled(), to match trace_enter() and trace_exit(). - trace_is_enabled() becomes a real function. - Remove unnecessary include files from various files that used to care about KTRACE and SYSTRACE, but do no more.

1.24.6.2	14-May-2008	wrstuden	Per discussion with ad, remove most of the #include <sys/sa.h> lines as they were including sa.h just for the type(s) needed for syscallargs.h. Instead, create a new file, sys/satypes.h, which contains just the types needed for syscallargs.h. Yes, there's only one now, but that may change and it's probably more likely to change if it'd be difficult to handle. :-) Per discussion with matt at n dot o, add an include of satypes.h to sigtypes.h. Upcall handlers are kinda signal handlers, and signalling is the header file that's already included for syscallargs.h that closest matches SA. This shaves about 3000 lines off of the diff of the branch relative to the base. That also represents about 18% of the total before this checkin. I think this reduction is very good thing.
1.24.6.1	10-May-2008	wrstuden	Initial checkin of re-adding SA. Everything except kern_sa.c compiles in GENERIC for i386. This is still a work-in-progress, but this checkin covers most of the mechanical work (changing signalling to be able to accomidate SA's process-wide signalling and re-adding includes of sys/sa.h and savar.h). Subsequent changes will be much more interesting. Also, kern_sa.c has received partial cleanup. There's still more to do, though.

1.31.16.13	03-Oct-2018	pgoyette	Normalize the required lists. Each compat_netbsd32_xx needs the non-32bit module of the same version _and_ the 32-bit module for the next higher version.
1.31.16.12	03-Oct-2018	pgoyette	Make sure that each version-specific compat_netbsd32_xx module depends on all higher-version-specific modules, similar to the non-32bit compat_xx modules.
1.31.16.11	25-Sep-2018	pgoyette	Additional use of NTP function pointers, since the NTP code might not exist in the kernel. (NTP is not (yet) a module, so we don't need to use the MP-safe mechanism.)
1.31.16.10	23-Sep-2018	pgoyette	Revert previous. Instead, don't put an entry for ntp_gettime in the syscall package if we don't have NTP.

1.59	01-Jan-2020	maxv	Fix sizeof mismatch in copyin. This leads to a user-triggerable stack overflow. On my test build at least, by luck, the compiler orders the variables in a way that the overflow hits only local structures which haven't yet been initialized and used, so the overflow is harmless. Very easily seeable with kASan - just invoke the syscall from a 32bit binary.

A few 'compat' routines that just call standard ones have been deleted. All the 'compat' code compiles (along with the kernels required to test build it). 98% done by automated scripts.

1.44	30-Jun-2007	dsl	branches: 1.44.6; 1.44.8; 1.44.14; 1.44.16; Changes to sompat socket function to avoid the dreaded stackgap.
1.43	16-Jun-2007	dsl	The code to directly call sigaction1() and sigaltstack1() is much shorter than the mess required to call the compat_43_xxx functions.
1.42	03-Jun-2007	dsl	sendmsg() shouldn't modify the 'msg' parameter, and recvmsg() doesn't have to modify the 'iov' array - it isn't updated.
1.41	30-Apr-2007	dsl	Rework compat stat() and statvfs() code so that it no longer uses the stackgap.
1.40	22-Apr-2007	dsl	Change the way that emulations locate files within the emulation root to avoid having to allocate space in the 'stackgap' - which is very LWP unfriendly. The additional code for non-emulation namei() is trivial, the reduction for the emulations is massive. The vnode for a processes emulation root is saved in the cwdi structure during process exec. If the emulation root the TRYEMULROOT flag are set, namei() will do an initial search for absolute pathnames in the emulation root, if that fails it will retry from the normal root. ".." at the emulation root will always go to the real root, even in the middle of paths and when expanding symlinks. Absolute symlinks found using absolute paths in the emulation root will be relative to the emulation root (so /usr/lib/xxx.so -> /lib/xxx.so links inside the emulation root don't need changing). If the root of the emulation would be returned (for an emulation lookup), then the real root is returned instead (matching the behaviour of emul_lookup, but being a cheap comparison here) so that programs that scan "../.." looking for the root dircetory don't loop forever. The target for symbolic links is no longer mangled (it used to get the CHECK_ALT_xxx() treatment, so could get /emul/xxx prepended). CHECK_ALT_xxx() are no more. Most of the change is deleting them, and adding TRYEMULROOT to the flags to NDINIT(). A lot of the emulation system call stubs could now be deleted.
1.39	18-Mar-2007	dsl	Change all the NETBSD32PTR64(SCARG(uap, xxx))) to SCARG_P32(uap, xxx).
1.38	16-Mar-2007	dsl	remove all the double (and triple) casts used to convert 32bit userspace pointers to and from 64bit kernel pointers. Instead use the defines NETBSD32PTR64(p32) to read a 32bit pointer and (the new) NETBSD32PTR32(p32,p64) to write a 32bit pointer throughout. The 32bit pointer is now a struct to enforce the above. amd64 (with linux emul) and sparc64 will both compile (when the arch stuff goes in soon), and amd64 still runs some i386 binaries.

Now all nodes are registered with the tree, and nodes can be added (or removed) easily, and I/O to and from the tree is handled generically. Since the nodes are registered with the tree, the mapping from name to number (and back again) can now be discovered, instead of having to be hard coded. Adding new nodes to the tree is likewise much simpler -- the new infrastructure handles almost all the work for simple types, and just about anything else can be done with a small helper function. All existing nodes are where they were before (numerically speaking), so all existing consumers of sysctl information should notice no difference. PS - I'm sorry, but there's a distinct lack of documentation at the moment. I'm working on sysctl(3/8/9) right now, and I promise to watch out for buses.

1.23	23-Oct-2002	scw	In preparation for COMPAT_NETBSD32 on SH-5: - The MD netbsd32_machdep.h header now defines the 32-bit pointer type instead of using u_int32_t everywhere, - The MD netbsd32_machdep.h header now defines a macro (at least on current implementations) which converts a 32-bit pointer to its 64-bit equivalent, - Change the MI code to utilise the above two items in all the right places, - Implement netbsd32___sigaction_sigtramp(). Tested on Sparc64 by Matt Green.
1.22	04-May-2002	martin	Add missing prototype for compat_43_netbsd32_sigsetmask.
1.21	16-Mar-2002	christos	make the stackgap_{init,alloc} functions MP friendly (i.e. pass struct proc * in, instead of using curproc). While there add an optional size argument to stackgap_init.
1.20	13-Nov-2001	lukem	add RCSIDs (including regeneration of files as appropriate)
1.19	25-Aug-2001	mrg	update copyright notices.
1.18	15-Aug-2001	eeh	Fix bug in netbsd32_compat_43_olseek return value.
1.17	30-May-2001	mrg	branches: 1.17.2; use _KERNEL_OPT.
1.16	05-Feb-2001	mrg	branches: 1.16.2; fix the glaring errors in emulations for osendmsg, orecvmsg, osigvec and osigstack.
1.15	02-Feb-2001	mrg	properly implement compat_43_netbsd32_stat43, compat_43_netbsd32_lstat43 and compat_43_netbsd32_fstat43. now 32-bit ls(1) works. so does static sunos `/sbin/sh' on sparc64.
1.14	02-Feb-2001	mrg	de-static netbsd32_exec_aout_prep_[zno]magic(). de-static netbsd32_from_stat43(). move the guts of netbsd32_execve() into netbsd32_execve2(). all of are for the forthcoming sunos32 compat mode (for sparc64).
1.13	03-Dec-2000	fvdl	Include opt_* files to make sure prototypes are included.
1.12	01-Dec-2000	jdolecek	add e_path (emulation path) to struct emul, which replaces emulation-specific _emul_path variables change macros CHECK_ALT_{CREAT\|EXIST} to use that, 'root' doesn't need to be passed explicitly any more and _CHECK_ALT_{CREAT\|EXIST} are removed change explicit emul_find() calls in probe functions to get the emulation path from the checked exec switch entry's emulation remove no longer needed header files add e_flags and e_syscall to struct emul; these are unsed and empty for now
1.11	24-Sep-2000	martin	The ovadvise syscall is (correctly) listed as STD, so move it's implementation to another place. This makes kernels without options COMPAT_43 link.
1.10	28-Jun-2000	mrg	remove include of <vm/vm.h>. <vm/vm.h> -> <uvm/uvm_extern.h>
1.9	30-Dec-1999	eeh	Update to 32-bit compatibility routines.
1.8	11-Oct-1999	eeh	branches: 1.8.2; Add netbsd32_compat_14.c Rename everything from compat_netbsd32 -> netbsd32 so we don't have silly names like compat_14_compat_netbsd32_sys_shmctl().
1.7	14-Apr-1999	mrg	branches: 1.7.2; fix errors in the copyright on this.
1.6	25-Mar-1999	mrg	branches: 1.6.2; SPARC32->NETBSD32
1.5	25-Mar-1999	mrg	move sparc32 to netbsd32; split out MD part (signal handling) (mostly via repository copy, rename and perl -pi :-)
1.4	01-Oct-1998	eeh	Overhaul. Now will run simple things like /bin/sh and /bin/echo.
1.3	29-Aug-1998	mrg	move <vm/vm_swap.h> to <sys/swap.h>. <vm/vm_swap.h> still works for now (goes away later)
1.2	26-Aug-1998	mrg	use right syscalls
1.1	26-Aug-1998	mrg	add a 32-bit compatibility module for the sparc64 port, so it can run NetBSD/sparc binaries with a LP64 kernel.
1.6.2.1	15-Apr-1999	mrg	branches: 1.6.2.1.2; pull up 1.7

1.27.2.1	02-Jul-2003	darrenr	Apply the aborted ktrace-lwp changes to a specific branch. This is just for others to review, I'm concerned that patch fuziness may have resulted in some errant code being generated but I'll look at that later by comparing the diff from the base to the branch with the file I attempt to apply to it. This will, at the very least, put the changes in a better context for others to review them and attempt to tinker with removing passing of 'struct lwp' through the kernel.

1.49.6.3	23-Jun-2008	wrstuden	Sync w/ -current. 34 merge conflicts to follow.
1.49.6.2	14-May-2008	wrstuden	Per discussion with ad, remove most of the #include <sys/sa.h> lines as they were including sa.h just for the type(s) needed for syscallargs.h. Instead, create a new file, sys/satypes.h, which contains just the types needed for syscallargs.h. Yes, there's only one now, but that may change and it's probably more likely to change if it'd be difficult to handle. :-) Per discussion with matt at n dot o, add an include of satypes.h to sigtypes.h. Upcall handlers are kinda signal handlers, and signalling is the header file that's already included for syscallargs.h that closest matches SA. This shaves about 3000 lines off of the diff of the branch relative to the base. That also represents about 18% of the total before this checkin. I think this reduction is very good thing.
1.49.6.1	10-May-2008	wrstuden	Initial checkin of re-adding SA. Everything except kern_sa.c compiles in GENERIC for i386. This is still a work-in-progress, but this checkin covers most of the mechanical work (changing signalling to be able to accomidate SA's process-wide signalling and re-adding includes of sys/sa.h and savar.h). Subsequent changes will be much more interesting. Also, kern_sa.c has received partial cleanup. There's still more to do, though.

1.57.4.3	08-Mar-2020	martin	Pull up following revision(s) (requested by pgoyette in ticket #761): sys/compat/netbsd32/syscalls.master: revision 1.132 sys/compat/netbsd32/netbsd32_compat_43.c: revision 1.60 Properly mark netbsd32_compat_43 syscalls that are directly implemented by calling their compat_43 equivalents.

1.57.4.2	02-Jan-2020	martin	Pull up following revision(s) (requested by maxv in ticket #597): sys/compat/common/kern_sig_43.c: revision 1.36 sys/compat/netbsd32/netbsd32_compat_20.c: revision 1.39 sys/compat/netbsd32/netbsd32_compat_43.c: revision 1.59 sys/compat/netbsd32/netbsd32_compat_50.c: revision 1.44 Fix sizeof mismatch in copyin. This leads to a user-triggerable stack overflow. On my test build at least, by luck, the compiler orders the variables in a way that the overflow hits only local structures which haven't yet been initialized and used, so the overflow is harmless. Very easily seeable with kASan - just invoke the syscall from a 32bit binary. Fix three stack info leaks, found by kMSan when just invoking all syscalls with a zero page as argument. MSan: Uninitialized Stack Memory In copyout() At Offset 0, Variable 'sb32' From compat_20_netbsd32_getfsstat() MSan: Uninitialized Stack Memory In copyout() At Offset 12, Variable 'oss' From compat_43_sys_sigstack() MSan: Uninitialized Stack Memory In copyout() At Offset 0, Variable 'sb' From compat_50_netbsd32___fhstat40()

Fix stupid bugs in linux_sys_shmctl(): the index could be out of bound (page fault) and there was no proper locking. Maybe we should just remove LINUX_SHM_STAT, like compat_linux32. Remove printf. When dealing with an unknown value, set -1, to prevent (harmless) uninitialized accesses later. Add a default case, don't call sys_ioctl() with an uninitialized 'com' argument. Fix error handling, returns an errno, not -1. Put the printf under DEBUG_LINUX. Hum, don't forget the 'pid' argument, otherwise we're not gonna go very far. Don't read data from userland directly. This simply does not work on any recent x86 CPU (thanks to SMAP) and all architectures that forbid direct access to userland from the kernel. But I guess no one noticed because no one ever uses compat_linux, right? Hum, don't pass an mbuf to realloc(). Inspired from copyin32_msg_control(). Fix memory leak. I don't see the point in having this useless printf, but add a '\n' to it, so that it at least displays useless stuff correctly. Hum, remove incorrect assignment. Userland could have passed a smaller namelen, and the uninitialized bytes from sb_data were being used later in the network stack.

1.56	29-Jul-2023	rin	COMPAT_NETBSD32: Reorganize the previous; Make compat_netbsd32_50 recursively depended on compat_netbsd32_100, rather than directly depended on it. Thanks pgoyette@ again for useful comments!
1.55	29-Jul-2023	rin	Now, netbsd32_compat_50 module requires netbsd32_compat_100. Thanks pgoyette@ for hints.
1.54	29-Jul-2023	rin	COMPAT_NETBSD32: Catch up with sys___kevent100() addition. XXX Add epoll_* and memfd_create.
1.53	26-Oct-2022	riastradh	sys: Put externs for time_adjtime and time_adjusted in .h files. time_adjtime: sys/timex.h (defined in ntp code) time_adjusted: sys/timevar.h (defined in non-ntp code) (Not really sure this is a valuable distinction to maintain; there's non-ntp code that uses time_adjtime too.)
1.52	07-Sep-2021	riastradh	sys/compat: Memset zero before copyout. Just in case of uninitialized padding which would lead to kernel stack disclosure. If the compiler can prove the memset redundant then it can optimize it away; otherwise better safe than sorry.
1.51	18-Feb-2021	simonb	In the compat setitimer(2) calls, don't validate which timer is being used since dosetitimer() does this anyway. The compat functions hadn't been updated since ITIMER_MONOTONIC was introduced, so they reported that that ITIMER_MONOTONIC timer was invalid.
1.50	19-Jan-2021	simonb	KNF consistency: No parentheses are needed around the return value.
1.49	30-Apr-2020	riastradh	branches: 1.49.2; Omit needless #include <sys/rnd.h>.
1.48	15-Mar-2020	pgoyette	Now that we have split the quota code out of the compat_netbsd32_50 module, it no longer depends on compat_50_quota. Should address PR kern/55073
1.47	12-Mar-2020	pgoyette	Split out the quota code from the rest of compat_netbsd32 module. This allows loading of compat_netbsd32 on kernels that don't have ``options QUOTA'' enabled.
1.46	27-Feb-2020	pgoyette	Module compat_netbsd32_50 requires module compat_50_quota
1.45	29-Jan-2020	ad	- Track LWPs in a per-process radixtree. It uses no extra memory in the single threaded case. Replace scans of p->p_lwps with lookups in the tree. Find free LIDs for new LWPs in the tree. Replace the hashed sleep queues for park/unpark with lookups in the tree under cover of a RW lock. - lwp_wait(): if waiting on a specific LWP, find the LWP via tree lookup and return EINVAL if it's detached, not ESRCH. - Group the locks in struct proc at the end of the struct in their own cache line. - Add some comments.
1.44	01-Jan-2020	maxv	branches: 1.44.2; Fix three stack info leaks, found by kMSan when just invoking all syscalls with a zero page as argument.

1.43	15-Dec-2019	tsutsui	Remove clause 3 and 4 leftovers from TNF licenses in more sources. Confirmed by martin@ in PR/54760.
1.42	12-Dec-2019	pgoyette	Rather than keeping a separate mutex, condvar, and pserialize for each module hook, we can share a common set of synchronization structures. This cuts the amount of cacheline_aligned data for these structures by 50%. Note that we still have a per-hook localcount, since we need to count individual references. As discussed with riastradh@ Welcome to 9.99.22 !
1.41	05-Oct-2019	kamil	Validate input before converting timeval::tv_usec in compat/netbsd32
1.40	20-Sep-2019	kamil	Validate usec ranges in compat_50_netbsd32_select() Later in the code selcommon() checks for proper timespec, check only correct usec of timeval before type conversions.
1.39	27-Jun-2019	christos	branches: 1.39.2; Include the right stuff so compat_netbsd32_50 compiles.
1.38	18-Jun-2019	kamil	Drop unused retval pointer from do_sys_mknod{,at}() No functional change intended.
1.37	18-Jun-2019	christos	regen
1.36	01-Mar-2019	pgoyette	Rename the MODULE__HOOK() macros to MODULE_HOOK_() as briefly discussed on irc. NFCI intended. Ride the earlier kernel bump - it;s getting crowded.
1.35	29-Jan-2019	pgoyette	Normalize all the compat hooks' names to the form <subsystem>_<function>_<version>_hook NFCI XXX Note that although this introduces a change in the kernel-to- XXX module interface, we are NOT bumping the kernel version number. XXX We will bump the version number once the interface stabilizes.
1.34	27-Jan-2019	pgoyette	Merge the [pgoyette-compat] branch
1.33	26-Dec-2018	mrg	remove duplicated prototypes and dated XXX comments.
1.32	03-Dec-2015	pgoyette	branches: 1.32.10; 1.32.16; 1.32.18; Split out the SYSV IPC stuff into its own compat_netbsd32_sysvipc module. Adjust dependencies as needed.
1.31	01-Dec-2015	pgoyette	Prepare for new compat_netbsd32_mqueue module to be split out of compat_netbsd32. Refactor the COMPAT_50 code related to mqueue, and update the syscall definitions. Remove dependency on mqueue from the compat_netbsd32 module (the new module will gain this dependency). Continuation of work on PR kern/50489
1.30	24-Jul-2015	maxv	Unused inits (harmless). Found by Brainy.
1.29	21-Jun-2015	martin	Move compat calls, requested by mrg@
1.28	27-Oct-2014	christos	branches: 1.28.2; fix multiple mistakes: - error from copyout was ignored - the wrong size was specified in copyin - missing locking.
1.27	05-Sep-2014	matt	Try not to use f_data, use f_{vnode,socket,pipe,mqueue,kqueue,ksem} to get a correctly typed pointer.
1.26	05-Sep-2014	matt	Don't use private as a variable name since it's reserved in C++
1.25	21-Aug-2014	maxv	Remove dead returns: return VAR/func(XX); return VAR; The latter is never reached. Sent on tech-kern@, no disagreement.
1.24	24-Jun-2014	maxv	branches: 1.24.2; Allocate directly KQ_NEVENTS bytes. Otherwise a user can panic the system. ok christos@
1.23	29-Mar-2013	christos	branches: 1.23.8; compat glue for new lwp_park
1.22	03-Nov-2012	njoly	Move rusage computation to a new getrusage1() function. Adjust all compat/emulations to make use of it.
1.21	02-Oct-2012	christos	kernel portion of clock_nanosleep()
1.20	18-Nov-2011	christos	branches: 1.20.6; 1.20.10; 1.20.12; 1.20.14; add a copyin function for sigset so that we can use sigtimedwait1 from emulations.
1.19	23-May-2011	joerg	branches: 1.19.4; Update from GNU extension to C99 syntax for designated initializer
1.18	06-Mar-2011	bouyer	merge the bouyer-quota2 branch. This adds a new on-disk format to store disk quota usage and limits, integrated with ffs metadata. Usage is checked by fsck_ffs (no more quotacheck) and is covered by the WAPBL journal. Enabled with kernel option QUOTA2 (added where QUOTA was enabled in kernel config files), turned on with tunefs(8) on a per-filesystem basis. mount_mfs(8) can also turn quotas on. See http://mail-index.netbsd.org/tech-kern/2011/02/19/msg010025.html for details.
1.17	30-May-2010	drochner	branches: 1.17.2; 1.17.4; -fix internal use of sigwaitinfo(2) by sigwait(3): The former returns the signal number now, as required by POSIX. The latter should just return 0 on success. Fixes a mysql problem reported by Kurt Schreiner. -document the new behavior of sigwaitinfo and sigtimedwait -retain non-POSIX behavior for NetBSD-5 binary compatibility -- the fix would likely not be polled into the .0-branches, and having 5.0.x and 5.x behave differently would be confusing. Besides that, it was documented in the manpage all the time.
1.16	23-Apr-2010	rmind	Replace M_IOV and some malloc(9)s with kmem(9), and while there: - Fix invalid free (M_TEMP vs M_IOV) in do_sys_recvmsg(), spotted by jakllsch@. Also, same fix in osf1_sys_sendmsg_xopen(). - Fix attempt to free non-allocated memory in error path in netbsd32___getfh30(). - Plug a memory leak in compat_43_netbsd32_orecvmsg().
1.15	08-Apr-2010	njoly	Add a new clock_gettime1() function that holds most of the clock_gettime syscall code (except for the copyout). Adjust all corresponding syscalls to make use of it.
1.14	03-Apr-2010	njoly	Move most clock_getres syscall code, except for coypout call, to a new clock_getres1() function which can be used by emulations. Adjust all clock_getres syscalls to now make of use it.
1.13	29-Mar-2010	njoly	Convert linux/linux32/netbsd32 clock_settime syscalls, to use the common clock_settime1() function.
1.12	29-Mar-2010	njoly	Make compat netbsd32 clock_getres copyout the netbsd32 timespec structure, not the native one.
1.11	28-Mar-2010	njoly	Cleanup compat netbsd32 nanosleep syscalls to use the common nanosleep1() call instead of their own stuff.
1.10	02-Mar-2010	pooka	branches: 1.10.2; regen for conditional lfs syscall removal
1.9	19-Jan-2010	pooka	branches: 1.9.2; A few more instances of __sigtimedwait1 -> sigtimedwait1
1.8	21-Dec-2009	njoly	Do not include fs_lfs.h unless _KERNEL_OPT is defined.
1.7	11-Nov-2009	rmind	- selcommon/pollcommon: drop redundant l argument. - Use cached curlwp->l_fd, instead of p->p_fd. - Inline selscan/pollscan.
1.6	04-Nov-2009	rmind	do_sys_wait(): fix previous by checking for ru != NULL. Noticed by Onno van der Linden. Also, remove redundant arguments (seems that was_zombie was not used since rev 1.177 ?).
1.5	09-Aug-2009	haad	Add enum uio_seg argument to do_sys_mknod and do_sys_mkdir so these functions can be called from kernel, too. Change needed for zfs device node creation, until we have propoer devfs. Oked by ad@.
1.4	29-Mar-2009	christos	branches: 1.4.2; Move the internal poll/select related API's to use timespec instead of timeval (rides the uvm bump).
1.3	26-Jan-2009	njoly	branches: 1.3.2; Make all fstat(2) compat syscalls consistently use do_sys_fstat(), instead of fd_getfile()/fd_putfile() dance. ok by christos.

1.32.16.16	23-Jan-2019	pgoyette	Convert the macros for setting and unsetting a hook to generate in-line code rather than using an intermediary hook##set routine. Hooks are set and unset only in one place, so the intermediary routine provides no benefit. IMHO using the macro at the point- of-call is more readable than using it elsewhere in the code and then calling the generated intermediary routine (for which you won't even find its declaration or definition unless you remember to search for the HOOK_SET macro instead). NFC intended, will verify with a bulk build and an atf test run.

1.32.16.14	26-Nov-2018	pgoyette	Sync with HEAD, resolve a couple of conflicts
1.32.16.13	12-Oct-2018	pgoyette	Use a MP-safe hook for the rnd_ioctl compat_50 calls.
1.32.16.12	03-Oct-2018	pgoyette	Normalize the required lists. Each compat_netbsd32_xx needs the non-32bit module of the same version _and_ the 32-bit module for the next higher version.
1.32.16.11	03-Oct-2018	pgoyette	Make sure that each version-specific compat_netbsd32_xx module depends on all higher-version-specific modules, similar to the non-32bit compat_xx modules.
1.32.16.10	25-Sep-2018	pgoyette	Additional use of NTP function pointers, since the NTP code might not exist in the kernel. (NTP is not (yet) a module, so we don't need to use the MP-safe mechanism.)
1.32.16.9	23-Sep-2018	pgoyette	Be selective about including the NTP syscall ntp_gettime
1.32.16.8	11-Sep-2018	pgoyette	Move the NTP compat_30 and compat_50 routines into the version-specific modules.
1.32.16.7	11-Sep-2018	pgoyette	Move netbsd32_rndpseudo_50.c out of the main netbsd32 module and into the module that handles netbsd32_50 compatability.
1.32.16.6	11-Sep-2018	pgoyette	Put the ``extern struct emul'' into the netbsd32_netbsd.h header so it doesn't have to be separately declared in each source file. Thanks mrg@
1.32.16.5	11-Sep-2018	pgoyette	Also need to declare the emul_netbsd32 !
1.32.16.4	11-Sep-2018	pgoyette	Install the syscalls into the netbsd32 table, not the default/native table.
1.32.16.3	11-Sep-2018	pgoyette	Use netbsd32 syscall names in the establish/disestablish tables
1.32.16.2	11-Sep-2018	pgoyette	Regen syscall files and fix includes for syscallvar.h

This leads to a user-triggerable stack overflow. On my test build at least, by luck, the compiler orders the variables in a way that the overflow hits only local structures which haven't yet been initialized and used, so the overflow is harmless. Very easily seeable with kASan - just invoke the syscall from a 32bit binary. Fix three stack info leaks, found by kMSan when just invoking all syscalls with a zero page as argument.

1.7	29-Jul-2023	rin	COMPAT_NETBSD32: Reorganize the previous; Make compat_netbsd32_50 recursively depended on compat_netbsd32_100, rather than directly depended on it. Thanks pgoyette@ again for useful comments!
1.6	12-Dec-2019	pgoyette	branches: 1.6.26; Rather than keeping a separate mutex, condvar, and pserialize for each module hook, we can share a common set of synchronization structures. This cuts the amount of cacheline_aligned data for these structures by 50%. Note that we still have a per-hook localcount, since we need to count individual references. As discussed with riastradh@ Welcome to 9.99.22 !
1.5	01-Mar-2019	pgoyette	branches: 1.5.4; Rename the MODULE__HOOK() macros to MODULE_HOOK_() as briefly discussed on irc. NFCI intended. Ride the earlier kernel bump - it;s getting crowded.
1.4	30-Jan-2019	pgoyette	Remove #ifdef COMPAT_80 The file will only be selected if "options COMPAT_80" is defined in the config file. The COMPAT_80 macro is defined only if the option is explicitly defined, and not if it is implicitly defined due to inclusion of lesser-version COMPATs.

1.1.2.6	23-Jan-2019	pgoyette	Convert the macros for setting and unsetting a hook to generate in-line code rather than using an intermediary hook##set routine. Hooks are set and unset only in one place, so the intermediary routine provides no benefit. IMHO using the macro at the point- of-call is more readable than using it elsewhere in the code and then calling the generated intermediary routine (for which you won't even find its declaration or definition unless you remember to search for the HOOK_SET macro instead). NFC intended, will verify with a bulk build and an atf test run.
1.1.2.5	18-Sep-2018	pgoyette	The COMPAT_HOOK macros were renamed to MODULE_HOOK, adjust all callers

1.46	07-Sep-2021	riastradh	sys/compat: Memset zero before copyout. Just in case of uninitialized padding which would lead to kernel stack disclosure. If the compiler can prove the memset redundant then it can optimize it away; otherwise better safe than sorry.
1.45	19-Jan-2021	simonb	The read/write/send/recv system calls return ssize_t because -1 is returned on error. Therefore we must restrict the lengths of any buffers to NETBSD32_SSIZE_MAX with compat32 to avoid garbage return values. Fixes ATF lib/libc/sys/t_write:write_err.

1.40	03-Oct-2019	kamil	Switch kevent udata from intptr_t void* Synchromize the struct field format with other BSDs and Darwin. No ABI change between older and newer struct form on the ports. The change will require no changes to most C users during the transition period as the header keeps a caller cast. Discussed with core@ and there were no objections for this move.

1.38	21-Feb-2019	mrg	branches: 1.38.4; for sysv ipc stat operations, explicitly copy the exported parts instead of the whole ds structure. besides triggering a recently added assert in netbsd32, this stops exposing kernel addresses. copy the mode clamping to 0777 from sem to shm and msg. while here, make sure that the compat callers to sysv_ipc clear the contents of the compat structure before setting the result members to ensure padding bytes are cleared. don't set/copy _sem_base, _msg_first, _msg_last or _shm_internal. even if used, which seems very dodgy, they leak KVAs as well. possibly this may affect linux binaries, in particular, the comments around _shm_internal ("XXX Oh well.") may mean apps rely upon these but hopefully not -- the comments date back to rev 1.1 in 1995. the _key, _seq and _msg_cbytes members are exported as before as i found multiple consumers of these (no less than ipcs(1), and they appear to be useful for debugging and more. XXX: the naming of compat functions have too many styles. there are at least 3 different ones changed here.

The 32bit pointer is now a struct to enforce the above. amd64 (with linux emul) and sparc64 will both compile (when the arch stuff goes in soon), and amd64 still runs some i386 binaries.

1.14	16-Feb-2006	perry	branches: 1.14.20; Change "inline" back to "__inline" in .h files -- C99 is still too new, and some apps compile things in C89 mode. C89 keywords stay. As per core@.
1.13	24-Dec-2005	perry	branches: 1.13.2; 1.13.4; 1.13.6; Remove leading __ from __(const\|inline\|signed\|volatile) -- it is obsolete.
1.12	11-Dec-2005	christos	merge ktrace-lwp.
1.11	23-Oct-2005	cube	- Split sys_kevent into kevent1 so that it can be used by COMPAT_NETBSD32 code. - To achieve COMPAT_NETBSD32 compatibility, introduce a parameter to kevent1 that points to functions that do the actual copyin/copyout operations. This is similar to what was done in FreeBSD by Paul Saab. - Add the COMPAT_NETBSD32 definitions and hooks.
1.10	13-Sep-2005	christos	branches: 1.10.2; make this compile again.
1.9	19-Aug-2005	christos	Fix lossage I created with the 64 bit ino_t change.
1.8	19-Aug-2005	christos	64 bit inode changes.

1.6	23-Jul-2005	cube	Implement the timer_create(2) family of syscalls.
1.5	26-Feb-2005	perry	branches: 1.5.4; nuke trailing whitespace
1.4	17-Jun-2004	cube	branches: 1.4.4; 1.4.6; o Add support for the statvfs family of syscalls (statvfs1, fstatvfs1, fhstatvfs1 and getvfsstat) o Move the statfs family out of netbsd32_fs.c and netbsd32_netbsd.c to netbsd_compat_20.c, compiled with COMPAT_20 Reviewed by christos@.
1.3	21-Apr-2004	christos	try to make this compile. XXX: this will not work yet (hi simon)
1.2	21-Apr-2004	christos	Replace the statfs() family of system calls with statvfs(). Retain binary compatibility.
1.1	07-Feb-2001	mrg	branches: 1.1.2; 1.1.26; move the static inline conversion functions into a header file so other files can see these. note a bunch of functions that should be moved into their own files.

1.38.4.1	03-Aug-2022	martin	Pull up following revision(s), all via patch (requested by riastradh in ticket #1489): sys/compat/netbsd32/netbsd32_netbsd.c: revision 1.232 sys/compat/netbsd32/netbsd32_socket.c: revision 1.56 sys/compat/netbsd32/netbsd32_conv.h: revision 1.45 sys/compat/netbsd32/netbsd32_fs.c: revision 1.92 sys/compat/netbsd32/netbsd32.h: revision 1.137 The read/write/send/recv system calls return ssize_t because -1 is returned on error.

1.42.8.1	03-Apr-2021	thorpej	Sync with HEAD.
1.18	08-Nov-2020	rin	Fix typo; s/__LP64/_LP64/
1.17	04-Nov-2020	pgoyette	Use opt_execfmt.h to get build options. Only include elf32 hooks if we have elf32 defined and elf32 is not the "native" emulation. This allows for having compat_netbsd32 without elf32 (although it's probably not too useful), and also enables arm's old-ABI usage of compat_netbsd32.
1.16	01-Nov-2020	pgoyette	Separate the compat_netbsd32_coredump from the compat_netbsd32 and coredump modules, into its own module. Welcome to 7.99.75 !!!
1.15	20-Nov-2019	pgoyette	branches: 1.15.8; Move all non-emulation-specific coredump code into the coredump module, and remove all #ifdef COREDUMP conditional compilation. Now, the coredump module is completely separated from the emulation modules, and they can all be independently loaded and unloaded. Welcome to 9.99.18 !
1.14	02-Feb-2011	chuck	branches: 1.14.56; udpate license clauses on my code to match the new-style BSD licenses. verified with Mike Hibler it is ok to remove clause 3 on utah copyright, as per UCB. based on diff that rmind@ sent me. no functional change with this commit.
1.13	11-Dec-2005	christos	branches: 1.13.100; 1.13.106; 1.13.108; merge ktrace-lwp.
1.12	10-Jun-2005	matt	Rework the coredump code to have no explicit knownledge of how coredump i/o is done. Instead, pass an opaque cookie which is then passed to a new routine, coredump_write, which does the actual i/o. This allows the method of doing i/o to change without affecting any future MD code. Also, make netbsd32_core.c [re]use core_netbsd.c (in a similar manner that core_elf64.c uses core_elf32.c) and eliminate that code duplication. cpu_coredump{,32} is now called twice, first with a NULL iocookie to fill the core structure and a second to actually write md parts of the coredump. All i/o is nolonger random access and is suitable for shipping over a stream.
1.11	02-Jun-2005	matt	When writing coredumps, don't write zero uninstantiated demand-zero pages. Also, with ELF core dumps, trim trailing zeroes from sections. These two changes can shrink coredumps by over 50% in size.
1.10	17-Sep-2004	skrll	There's no need to pass a proc value when using UIO_SYSSPACE with vn_rdwr(9) and uiomove(9). OK'd by Jason Thorpe
1.9	15-Sep-2003	christos	catch up with latest sigctx changes; reported by John Heasley, thanks!
1.8	07-Sep-2003	rafal	Catch up to Christos' SIGINFO changes.
1.7	29-Jun-2003	fvdl	branches: 1.7.2; Back out the lwp/ktrace changes. They contained a lot of colateral damage, and need to be examined and discussed more.
1.6	29-Jun-2003	martin	struct proc * -> struct lwp *
1.5	18-Jan-2003	thorpej	Merge the nathanw_sa branch.
1.4	10-Dec-2001	thorpej	branches: 1.4.2; 1.4.4; I can't win today -- make this link.
1.3	10-Dec-2001	thorpej	Move the code that walks the process's VM map during a coredump into uvm_coredump_walkmap(), and use callbacks into the coredump routine to do something with each section.
1.2	09-Dec-2001	thorpej	Fix compilation problems.
1.1	08-Dec-2001	thorpej	Make the coredump routine exec-format/emulation specific. Split out traditional NetBSD coredump routines into core_netbsd.c and netbsd32_core.c (for COMPAT_NETBSD32).
1.4.4.2	10-Jan-2002	thorpej	Sync kqueue branch with -current.
1.4.4.1	10-Dec-2001	thorpej	file netbsd32_core.c was added on branch kqueue on 2002-01-10 19:51:54 +0000
1.4.2.3	23-Aug-2002	petrov	lwpification.

1.4	28-Sep-2019	christos	branches: 1.4.8; fix sign-compare.
1.3	20-Aug-2019	christos	From maxv@: 1) In compat_drm_agp_info(), seems like it should be info64to32. 2) In compat_drm_getstats(), the assignments in the loop are inverted, it's st32 which should be set to the values of st64, not the other way around. 3) In compat_drm_dma(), again inverted 32<->64, and there is no copyout (?). 4) In compat_drm_agp_enable(), m64 is uninitialized, everything is wrong in this function it seems.
1.2	20-Aug-2019	christos	add NetBSD copyright.
1.1	20-Aug-2019	christos	compat32 drm ioctl support from Surya Shankar at GSoC 2019

1.4.8.1	28-Sep-2019	martin	file netbsd32_drm.c was added on branch phil-wifi on 2020-04-13 08:04:16 +0000
1.5	02-Sep-2023	mrg	redo previous: use same variable type for the interator as the comparison
1.4	30-Aug-2023	mrg	use unsigned for iterator, fixes -Wsigned-comapre issue in module build.
1.3	30-Jul-2023	rin	netbsd32_epoll_pwait2: Dedup slightly. NFCI.
1.2	30-Jul-2023	rin	netbsd32_epoll_pwait2: Early return if no event arrived; Do not attempt to allocate 0-byte buffer by kmem_alloc(9).

1.14	29-Jul-2023	rin	COMPAT_NETBSD32: No need to have compat_100_netbsd32_kevent_fetch_timeout. NFCI.
1.13	29-Jul-2023	rin	COMPAT_NETBSD32: Catch up with sys___kevent100() addition. XXX Add epoll_* and memfd_create.
1.12	05-Sep-2014	matt	Don't use private as a variable name since it's reserved in C++
1.11	24-Jun-2014	maxv	Allocate directly KQ_NEVENTS bytes. Otherwise a user can panic the system. ok christos@
1.10	23-Jan-2014	manu	branches: 1.10.2; Fix netbsd32 compatibility bug in kevent() The keo_put_events() callback copies the events from kernel to userland. It is called for sets of up to 8 events (constant chosen in kevbuf definitition in kevent1()). The callback is called with pointer to userland buffer, count of events to copy, and an index parameter which tracks where we are in userland buffer when called multiple time. COMPAT_NETBSD32's flavor of keo_put_events() is netbsd32_kevent_put_events(). It did not honour the index parameter, which caused invalid event data to be returned when userland requested more that 8 events. This caused many reliability problems, and the obvious startup crash of dovecot log process when it accessed udata in the nineth event in its buffer, which was NULL.
1.9	23-May-2011	joerg	branches: 1.9.4; 1.9.10; 1.9.14; 1.9.16; 1.9.18; 1.9.24; Update from GNU extension to C99 syntax for designated initializer
1.8	23-Apr-2010	rmind	branches: 1.8.2; Replace M_IOV and some malloc(9)s with kmem(9), and while there: - Fix invalid free (M_TEMP vs M_IOV) in do_sys_recvmsg(), spotted by jakllsch@. Also, same fix in osf1_sys_sendmsg_xopen(). - Fix attempt to free non-allocated memory in error path in netbsd32___getfh30(). - Plug a memory leak in compat_43_netbsd32_orecvmsg().
1.7	11-Jan-2009	christos	branches: 1.7.4; 1.7.6; merge christos-time_t
1.6	29-Apr-2008	martin	branches: 1.6.8; 1.6.14; Convert to new 2 clause license
1.5	21-Mar-2008	ad	branches: 1.5.2; 1.5.4; Catch up with descriptor handling changes. See kern_descrip.c revision 1.173 for details.
1.4	20-Dec-2007	dsl	branches: 1.4.6; Convert all the system call entry points from: int foo(struct lwp l, void v, register_t retval) to: int foo(struct lwp l, const struct foo_args uap, register_t retval) Fixup compat code to not write into 'uap' and (in some cases) to actually pass a correctly formatted 'uap' structure with the right name to the next routine. A few 'compat' routines that just call standard ones have been deleted. All the 'compat' code compiles (along with the kernels required to test build it). 98% done by automated scripts.
1.3	10-Sep-2007	cube	branches: 1.3.8; 1.3.12; Remove 3rd clause and my name from all the licences which were only in my name.
1.2	11-Dec-2005	christos	branches: 1.2.18; 1.2.32; 1.2.46; 1.2.48; merge ktrace-lwp.
1.1	23-Oct-2005	cube	branches: 1.1.4; 1.1.6; - Split sys_kevent into kevent1 so that it can be used by COMPAT_NETBSD32 code. - To achieve COMPAT_NETBSD32 compatibility, introduce a parameter to kevent1 that points to functions that do the actual copyin/copyout operations. This is similar to what was done in FreeBSD by Paul Saab. - Add the COMPAT_NETBSD32 definitions and hooks.

1.37	06-Nov-2021	thorpej	COMPAT_NETBSD32 is all about running the 32-bit flavor of native binaries on a 64-bit platform[], as such: - Make the logic about which "sendsig" flavor to call MI (as it is in the native 64-bit environment) and follow the same rules as the native 32-bit environment. - Make COMPAT_NETBSD32 x COMPAT_16 work the same as it would in the native 32-bit environment by providing a netbsd32_sendsig_sigcontext_16_hook, rather than overriding the entire sendsig logic with a netbsd32_sendsig_hook. - In netbsd32___sigaction_sigtramp(), make sure the compat_netbsd32_16 module is loaded if the trampoline version specifies a sigcontext style handler, otherwise return EINVAL so that libc can try again with siginfo style. [] ...except for arm32, which uses it to mean "run 32-bit OABI binaries from the 32-bit EABI environment". Doing it this way was arguably a mistake, but we are stuck with it for now, so support it by providing a machine- dependent override for netbsd32_sendsig() that also disables the corresponding logic in netbsd32___sigaction_sigtramp(). Fixes PR kern/56487.

1.24	16-Mar-2007	dsl	remove all the double (and triple) casts used to convert 32bit userspace pointers to and from 64bit kernel pointers. Instead use the defines NETBSD32PTR64(p32) to read a 32bit pointer and (the new) NETBSD32PTR32(p32,p64) to write a 32bit pointer throughout. The 32bit pointer is now a struct to enforce the above. amd64 (with linux emul) and sparc64 will both compile (when the arch stuff goes in soon), and amd64 still runs some i386 binaries.

1.30	06-Aug-2016	maxv	branches: 1.30.28; The way the kernel tries to prevent a userland process from allocating page zero is hugely flawed. It is easy to demonstrate that one can trick UVM into chosing a NULL hint after the user_va0_disable check from uvm_map. Such a bypass allows kernel NULL pointer dereferences to be exploitable on architectures with a shared userland<->kernel VA, like amd64. Fix this by increasing the limit of the vm space made available for userland processes. This way, UVM will never chose a NULL hint, since it would be outside of the vm space. The user_va0_disable sysctl still controls this feature.

This is just for others to review, I'm concerned that patch fuziness may have resulted in some errant code being generated but I'll look at that later by comparing the diff from the base to the branch with the file I attempt to apply to it. This will, at the very least, put the changes in a better context for others to review them and attempt to tinker with removing passing of 'struct lwp' through the kernel.

1.40	06-Aug-2016	maxv	branches: 1.40.14; 1.40.16; The way the kernel tries to prevent a userland process from allocating page zero is hugely flawed. It is easy to demonstrate that one can trick UVM into chosing a NULL hint after the user_va0_disable check from uvm_map. Such a bypass allows kernel NULL pointer dereferences to be exploitable on architectures with a shared userland<->kernel VA, like amd64. Fix this by increasing the limit of the vm space made available for userland processes. This way, UVM will never chose a NULL hint, since it would be outside of the vm space. The user_va0_disable sysctl still controls this feature.
1.39	20-Mar-2015	maxv	Zero-fill the ELF auxiliary vectors. Otherwise, on 64bit systems, the padding between a_v and a_type contains kernel garbage, therefore exposed to userland. Original report by uebayasi@

1.27	22-Apr-2007	dsl	branches: 1.27.28; 1.27.30; 1.27.32; 1.27.34; Change the way that emulations locate files within the emulation root to avoid having to allocate space in the 'stackgap' - which is very LWP unfriendly. The additional code for non-emulation namei() is trivial, the reduction for the emulations is massive. The vnode for a processes emulation root is saved in the cwdi structure during process exec. If the emulation root the TRYEMULROOT flag are set, namei() will do an initial search for absolute pathnames in the emulation root, if that fails it will retry from the normal root. ".." at the emulation root will always go to the real root, even in the middle of paths and when expanding symlinks. Absolute symlinks found using absolute paths in the emulation root will be relative to the emulation root (so /usr/lib/xxx.so -> /lib/xxx.so links inside the emulation root don't need changing). If the root of the emulation would be returned (for an emulation lookup), then the real root is returned instead (matching the behaviour of emul_lookup, but being a cheap comparison here) so that programs that scan "../.." looking for the root dircetory don't loop forever. The target for symbolic links is no longer mangled (it used to get the CHECK_ALT_xxx() treatment, so could get /emul/xxx prepended). CHECK_ALT_xxx() are no more. Most of the change is deleting them, and adding TRYEMULROOT to the flags to NDINIT(). A lot of the emulation system call stubs could now be deleted.

1.39	03-Sep-2018	riastradh	Rename min/max -> uimin/uimax for better honesty. These functions are defined on unsigned int. The generic name min/max should not silently truncate to 32 bits on 64-bit systems. This is purely a name change -- no functional change intended. HOWEVER! Some subsystems have #define min(a, b) ((a) < (b) ? (a) : (b)) #define max(a, b) ((a) > (b) ? (a) : (b)) even though our standard name for that is MIN/MAX. Although these may invite multiple evaluation bugs, these do _not_ cause integer truncation. To avoid `fixing' these cases, I first changed the name in libkern, and then compile-tested every file where min/max occurred in order to confirm that it failed -- and thus confirm that nothing shadowed min/max -- before changing it. I have left a handful of bootloaders that are too annoying to compile-test, and some dead code: cobalt ews4800mips hp300 hppa ia64 luna68k vax acorn32/if_ie.c (not included in any kernels) macppc/if_gm.c (superseded by gem(4)) It should be easy to fix the fallout once identified -- this way of doing things fails safe, and the goal here, after all, is to _avoid_ silent integer truncations, not introduce them. Maybe one day we can reintroduce min/max as type-generic things that never silently truncate. But we should avoid doing that for a while, so that existing code has a chance to be detected by the compiler for conversion to uimin/uimax without changing the semantics until we can properly audit it all. (Who knows, maybe in some cases integer truncation is actually intended!)

1.34	08-Apr-2012	martin	Rework posix_spawn locking and memory management: - always provide a vmspace for the new proc, initially borrowing from proc0 (this part fixes PR 46286) - increase parallelism between parent and child if arguments allow this, avoiding a potential deadlock on exec_lock - add a new flag for userland to request old (lockstepped) behaviour for better error reporting - adapt test cases to the previous two and add a new variant to test the diagnostics flag - fix a few memory (and lock) leaks - provide netbsd32 compat

1.31	20-Dec-2007	dsl	branches: 1.31.6; 1.31.8; 1.31.10; 1.31.12; Convert all the system call entry points from: int foo(struct lwp l, void v, register_t retval) to: int foo(struct lwp l, const struct foo_args uap, register_t retval) Fixup compat code to not write into 'uap' and (in some cases) to actually pass a correctly formatted 'uap' structure with the right name to the next routine. A few 'compat' routines that just call standard ones have been deleted. All the 'compat' code compiles (along with the kernels required to test build it). 98% done by automated scripts.
1.30	22-Apr-2007	dsl	branches: 1.30.8; 1.30.16; 1.30.20; Change the way that emulations locate files within the emulation root to avoid having to allocate space in the 'stackgap' - which is very LWP unfriendly. The additional code for non-emulation namei() is trivial, the reduction for the emulations is massive. The vnode for a processes emulation root is saved in the cwdi structure during process exec. If the emulation root the TRYEMULROOT flag are set, namei() will do an initial search for absolute pathnames in the emulation root, if that fails it will retry from the normal root. ".." at the emulation root will always go to the real root, even in the middle of paths and when expanding symlinks. Absolute symlinks found using absolute paths in the emulation root will be relative to the emulation root (so /usr/lib/xxx.so -> /lib/xxx.so links inside the emulation root don't need changing). If the root of the emulation would be returned (for an emulation lookup), then the real root is returned instead (matching the behaviour of emul_lookup, but being a cheap comparison here) so that programs that scan "../.." looking for the root dircetory don't loop forever. The target for symbolic links is no longer mangled (it used to get the CHECK_ALT_xxx() treatment, so could get /emul/xxx prepended). CHECK_ALT_xxx() are no more. Most of the change is deleting them, and adding TRYEMULROOT to the flags to NDINIT(). A lot of the emulation system call stubs could now be deleted.
1.29	18-Mar-2007	dsl	Change all the NETBSD32PTR64(SCARG(uap, xxx))) to SCARG_P32(uap, xxx).
1.28	04-Mar-2007	christos	branches: 1.28.2; 1.28.4; 1.28.6; Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.

1.26	07-Mar-2006	thorpej	branches: 1.26.2; 1.26.12; Clean up fallout proc_is_traced_p() change: - proc_is_traced_p() -> trace_is_enabled(), to match trace_enter() and trace_exit(). - trace_is_enabled() becomes a real function. - Remove unnecessary include files from various files that used to care about KTRACE and SYSTRACE, but do no more.
1.25	11-Dec-2005	christos	branches: 1.25.4; 1.25.6; 1.25.8; merge ktrace-lwp.
1.24	13-Jul-2005	cube	Do the CHECK_ALT_EXIST dance again in netbsd32_execve(). It was lost in previous commit.
1.23	11-Jul-2005	cube	Split sys_execve() and add execve1() that does most of the work, and takes as an argument a function that will retrieve an element of the pointer arrays in user space. This allows COMPAT_NETBSD32 to share the code for the emulated version of execve(2), and fixes various issues that came from the slow drift between the two implementations. Note: when splitting up a syscall function, I'll use two different ways of naming the resulting helper function. If it stills does copyin/out operations, it will be named <syscall>1(). If it does not (as it was the case for get/setitimer), it will be named do<syscall>.
1.22	31-May-2005	christos	branches: 1.22.2; - add const - avoid shadowed variables.
1.21	19-May-2005	elad	Some changes in veriexec. New features: - Add a veriexec_report() routine to make most reporting consistent and remove some common code. - Add 'strict' mode that controls how veriexec behaves. - Add sysctl knobs: o kern.veriexec.verbose controls verbosity levels. Value: 0, 1. o kern.veriexec.strict controls strict level. Values: 0, 1, 2. See documentation in sysctl(3) for details. o kern.veriexec.algorithms returns a string with a space separated list of supported hashing algorithms in veriexec. - Updated documentation in man pages for sysctl(3) and sysctl(8). Bug fixes: - veriexec_removechk(): Code cleanup + handle FINGERPRINT_NOTEVAL correctly. - exec_script(): Don't pass 0 as flag when executing a script; use the defined VERIEXEC_INDIRECT - which is 1. Makes indirect execution enforcement work. - Fix some printing formats and types..
1.20	01-Apr-2005	yamt	merge yamt-km branch. - don't use managed mappings/backing objects for wired memory allocations. save some resources like pv_entry. also fix (most of) PR/27030. - simplify kernel memory management API. - simplify pmap bootstrap of some ports. - some related cleanups.

1.15	28-Jun-2003	darrenr	Pass lwp pointers throughtout the kernel, as required, so that the lwpid can be inserted into ktrace records. The general change has been to replace "struct proc " with "struct lwp " in various function prototypes, pass the lwp through and use l_proc to get the process pointer when needed. Bump the kernel rev up to 1.6V

1.11	25-Aug-2002	thorpej	Fix some signed/unsigned comparison warnings from GCC 3.3.
1.10	06-Jun-2002	fvdl	Fix wrong psstr computation. (XXX why is there an entire copy of sys_execve here?)
1.9	22-Mar-2002	jdolecek	branches: 1.9.2; 1.9.4; invoke setregs hooks correctly, as in sys_execve() Problem noted and fix tested by Eduardo Horvath
1.8	16-Mar-2002	christos	make the stackgap_{init,alloc} functions MP friendly (i.e. pass struct proc * in, instead of using curproc). While there add an optional size argument to stackgap_init.
1.7	23-Nov-2001	jdolecek	branches: 1.7.4; if the LKM support is not compiled in, don't bother using exec_lock at all, it's only needed in LKM case use #if defined(LKM) \|\| defined(_LKM) condition for netbsd32_execve.c, to DTRT when either compiled statically into kernel with LKM support, or compiled as a LKM
1.6	13-Nov-2001	lukem	add RCSIDs (including regeneration of files as appropriate)
1.5	29-Jul-2001	christos	carry on the copyargs() and exit1() changes from kern_exec.c
1.4	15-Jun-2001	thorpej	branches: 1.4.2; In check_exec(), don't bother checking P_TRACED along with MNT_NOSUID, just check MNT_NOSUID to clear the S{U,G}ID bits in the attributes for the vnode we're about to exec. We now check P_TRACED right before we would actually perform the s{u,g}id function in the exec code. This closes a race condition between exec of a setuid binary and ptrace(2).

This will, at the very least, put the changes in a better context for others to review them and attempt to tinker with removing passing of 'struct lwp' through the kernel.

1.31.12.2	14-May-2008	wrstuden	Per discussion with ad, remove most of the #include <sys/sa.h> lines as they were including sa.h just for the type(s) needed for syscallargs.h. Instead, create a new file, sys/satypes.h, which contains just the types needed for syscallargs.h. Yes, there's only one now, but that may change and it's probably more likely to change if it'd be difficult to handle. :-) Per discussion with matt at n dot o, add an include of satypes.h to sigtypes.h. Upcall handlers are kinda signal handlers, and signalling is the header file that's already included for syscallargs.h that closest matches SA. This shaves about 3000 lines off of the diff of the branch relative to the base. That also represents about 18% of the total before this checkin. I think this reduction is very good thing.
1.31.12.1	10-May-2008	wrstuden	Initial checkin of re-adding SA. Everything except kern_sa.c compiles in GENERIC for i386. This is still a work-in-progress, but this checkin covers most of the mechanical work (changing signalling to be able to accomidate SA's process-wide signalling and re-adding includes of sys/sa.h and savar.h). Subsequent changes will be much more interesting. Also, kern_sa.c has received partial cleanup. There's still more to do, though.

1.95	23-Apr-2022	reinoud	Implement support for mounting UDF in compat32 Fixes PR#56801
1.94	11-Sep-2021	riastradh	sys/kern: Allow custom fileops to specify fo_seek method. Previously only vnodes allowed lseek/pread[v]/pwrite[v], which meant converting a regular device to a cloning device doesn't always work. Semantics is: (fp->f_ops->fo_seek)(fp, delta, whence, newoffp, flags) 1. Compute a new offset according to whence + delta -- that is, if whence is SEEK_CUR, add delta to fp->f_offset; if whence is SEEK_END, add delta to end of file; if whence is SEEK_CUR, use delta as is. 2. If newoffp is nonnull, return the new offset in newoffp. 3. If flags & FOF_UPDATE_OFFSET, set fp->f_offset to the new offset. Access to fp->f_offset, and *newoffp if newoffp = &fp->f_offset, must happen under the object lock (e.g., vnode lock), in order to synchronize fp->f_offset reads and writes. This change has the side effect that every call to VOP_SEEK happens under the vnode lock now, when previously it didn't. However, from a review of all the VOP_SEEK implementations, it does not appear that any file system even examines the vnode, let alone locks it. So I think this is safe -- and essentially the only reasonable way to do things, given that it is used to validate a change from oldoff to newoff, and oldoff becomes stale the moment we unlock the vnode. No kernel bump because this reuses a spare entry in struct fileops, and it is safe for the entry to be null, so all existing fileops will continue to work as before (rejecting seek).
1.93	16-Feb-2021	simonb	In netbsd32___mount50() zero out the native fs_args union before use so we don't pass stack garbage to the lower layers in the MNT_GETARGS case. Fixes random errors like "Bad address" from "mount -vv" with nfs mounts.
1.92	19-Jan-2021	simonb	The read/write/send/recv system calls return ssize_t because -1 is returned on error. Therefore we must restrict the lengths of any buffers to NETBSD32_SSIZE_MAX with compat32 to avoid garbage return values. Fixes ATF lib/libc/sys/t_write:write_err.
1.91	19-Jan-2021	simonb	KNF consistency: No parentheses are needed around the return value.
1.90	23-May-2020	ad	branches: 1.90.2; Move proc_lock into the data segment. It was dynamically allocated because at the time we had mutex_obj_alloc() but not __cacheline_aligned.
1.89	27-Apr-2020	christos	data_len == 0 on mount means "the kernel knows". Fixes amd on compat32.
1.88	21-Apr-2020	ad	Revert the changes made in February to make cwdinfo use mostly lockless, which relied on taking extra vnode refs. Having benchmarked various experimental changes over the past few months it seems that it's better to avoid vnode refs as much as possible. cwdi_lock as a RW lock already did that to some extent for getcwd() and will permit the same for namei() too.
1.87	23-Feb-2020	ad	branches: 1.87.4; Merge from ad-namecache: - Have a stab at clustering the members of vnode_t and vnode_impl_t in a more cache-conscious way. With that done, go back to adjusting v_usecount with atomics and keep vi_lock directly in vnode_impl_t (saves KVA). - Allow VOP_LOCK(LK_NONE) for the benefit of VFS_VGET() and VFS_ROOT(). Make sure LK_UPGRADE always comes with LK_NOWAIT. - Make cwdinfo use mostly lockless.

1.84	22-Sep-2019	christos	Add a new member to struct vfsstat and grow the unused members The new member is caled f_mntfromlabel and it is the dkw_wname of the corresponding wedge. This is now used by df -W to display the mountpoint name as NAME=
1.83	21-Sep-2019	maxv	Fix netbsd32___mount50(): - zero out fs_args32 to prevent info leaks - remove unused and non-functional copyin in NFS (lgtm bot) - declare udata, and don't pass kernel pointers to copyout (lgtm bot) - make sure data_len is just big enough, to mimic the native behavior - don't forget to update *retval with the 32bit value - add an XXX for NFS

1.53	24-Apr-2008	ad	branches: 1.53.2; 1.53.4; Network protocol interrupts can now block on locks, so merge the globals proclist_mutex and proclist_lock into a single adaptive mutex (proc_lock). Implications: - Inspecting process state requires thread context, so signals can no longer be sent from a hardware interrupt handler. Signal activity must be deferred to a soft interrupt or kthread. - As the proc state locking is simplified, it's now safe to take exit() and wait() out from under kernel_lock. - The system spends less time at IPL_SCHED, and there is less lock activity.
1.52	23-Apr-2008	ad	Fix locking.
1.51	21-Mar-2008	ad	branches: 1.51.2; Catch up with descriptor handling changes. See kern_descrip.c revision 1.173 for details.
1.50	05-Jan-2008	dsl	branches: 1.50.6; Use FILE_LOCK() and FILE_UNLOCK(). Attempt to fix all the code paths so that the 'fp' returned by fd_getfile() isn't left locked, and is always unlocked (and ref-counted) before doing anything that might sleep.
1.49	20-Dec-2007	dsl	Convert all the system call entry points from: int foo(struct lwp l, void v, register_t retval) to: int foo(struct lwp l, const struct foo_args uap, register_t retval) Fixup compat code to not write into 'uap' and (in some cases) to actually pass a correctly formatted 'uap' structure with the right name to the next routine. A few 'compat' routines that just call standard ones have been deleted. All the 'compat' code compiles (along with the kernels required to test build it). 98% done by automated scripts.

1.44	09-Jun-2007	ad	Acquire proclist_mutex before sending signals. XXX irix emul needs a bit of work.
1.43	12-May-2007	dsl	Change the compat sys_[fl]utime code to not use the stackgap.
1.42	30-Apr-2007	dsl	Split the statvfs functions so that the 'work' is done to a kernel buffer which can either be copied directly to userspace, or converted then copied. Saves replicating a lot of code in the compat functions (esp. for getvfsstat) at a cast of an extra function call in the non-emulated case - which is unlikely to be measurable given the other costs of the actions involved (even on vax). Remove dofhstat() and dofhstatvfs() (and the last caller). Remove some redundant stackgap_init() calls.
1.41	22-Apr-2007	dsl	Actually report an error when sys__stat30() fails.
1.40	22-Apr-2007	dsl	Change the way that emulations locate files within the emulation root to avoid having to allocate space in the 'stackgap' - which is very LWP unfriendly. The additional code for non-emulation namei() is trivial, the reduction for the emulations is massive. The vnode for a processes emulation root is saved in the cwdi structure during process exec. If the emulation root the TRYEMULROOT flag are set, namei() will do an initial search for absolute pathnames in the emulation root, if that fails it will retry from the normal root. ".." at the emulation root will always go to the real root, even in the middle of paths and when expanding symlinks. Absolute symlinks found using absolute paths in the emulation root will be relative to the emulation root (so /usr/lib/xxx.so -> /lib/xxx.so links inside the emulation root don't need changing). If the root of the emulation would be returned (for an emulation lookup), then the real root is returned instead (matching the behaviour of emul_lookup, but being a cheap comparison here) so that programs that scan "../.." looking for the root dircetory don't loop forever. The target for symbolic links is no longer mangled (it used to get the CHECK_ALT_xxx() treatment, so could get /emul/xxx prepended). CHECK_ALT_xxx() are no more. Most of the change is deleting them, and adding TRYEMULROOT to the flags to NDINIT(). A lot of the emulation system call stubs could now be deleted.
1.39	18-Mar-2007	dsl	Change all the NETBSD32PTR64(SCARG(uap, xxx))) to SCARG_P32(uap, xxx).
1.38	16-Mar-2007	dsl	remove all the double (and triple) casts used to convert 32bit userspace pointers to and from 64bit kernel pointers. Instead use the defines NETBSD32PTR64(p32) to read a 32bit pointer and (the new) NETBSD32PTR32(p32,p64) to write a 32bit pointer throughout. The 32bit pointer is now a struct to enforce the above. amd64 (with linux emul) and sparc64 will both compile (when the arch stuff goes in soon), and amd64 still runs some i386 binaries.
1.37	10-Mar-2007	dsl	branches: 1.37.2; 1.37.4; Update all the compat stuff to not use the 'stackgap' for processing sys_stat() and friends, instead use do_sys_stat() and do_sys_fstat() that write the answer into a kernel buffer (on stack) that can be converted to the correct form and written the userspace. I've test compiled a few kernels, and tested i386 netbsd1.6 ls. Given I think I've fixed some bugs, it might be 50-50 with new ones.

1.33	04-Aug-2006	yamt	branches: 1.33.4; 1.33.6; some filehandle syscall related changes. - remove the support of variable-sized filehandle from compat version of syscalls. (strictly speaking, it breaks abi. i don't think it's a problem because this feature is short-lived and there are no affected in-tree filesystems.) - unify vfs_copyinfh_alloc and vfs_copyinfh_alloc_size. - vfs_copyinfh_alloc_size: check fhsize strictly. - reduce code duplication between compat and current syscalls.

1.29	14-Jul-2006	martin	netbsd32_sys___fhstat30 and netbsd32_sys___fhstatvfs have nothing to do with compat_30 - so use full/variable sized filehandles here too. Fixes PR kern/34004.
1.28	13-Jul-2006	martin	Fix alignement problems for fhandle_t, exposed by gcc4.1. While touching all vptofh/fhtovp functions, get rid of VFS_MAXFIDSIZ, version the getfh(2) syscall and explicitly pass the size available in the filehandle from userland. Discussed on tech-kern, with lots of help from yamt (thanks!).

1.26	05-May-2006	cube	Move fhstat as sys___fhstat30 in netbsd32_fs.c because it doesn't belong to netbsd32_netbsd.c (which incidentally means it had been broken for a while I guess). Add compat_30 version.

1.12	28-Jun-2003	darrenr	Pass lwp pointers throughtout the kernel, as required, so that the lwpid can be inserted into ktrace records. The general change has been to replace "struct proc " with "struct lwp " in various function prototypes, pass the lwp through and use l_proc to get the process pointer when needed. Bump the kernel rev up to 1.6V
1.11	18-Jan-2003	thorpej	Merge the nathanw_sa branch.
1.10	23-Oct-2002	scw	In preparation for COMPAT_NETBSD32 on SH-5: - The MD netbsd32_machdep.h header now defines the 32-bit pointer type instead of using u_int32_t everywhere, - The MD netbsd32_machdep.h header now defines a macro (at least on current implementations) which converts a 32-bit pointer to its 64-bit equivalent, - Change the MI code to utilise the above two items in all the right places, - Implement netbsd32___sigaction_sigtramp(). Tested on Sparc64 by Matt Green.

1.7	13-Nov-2001	lukem	add RCSIDs (including regeneration of files as appropriate)
1.6	14-Jun-2001	thorpej	branches: 1.6.2; Fix a partial construction problem that can cause race conditions between creation of a file descriptor and close(2) when using kernel assisted threads. What we do is stick descriptors in the table, but mark them as "larval". This causes essentially everything to treat it as a non-existent descriptor, except for fdalloc(), which sees a filled slot so that it won't (incorrectly) allocate it again. When a descriptor is fully constructed, the code that has constructed it marks it as "mature" (which actually clears the "larval" flag), and things continue to work as normal. While here, gather all the code that gets a descriptor from the table into a fd_getfile() function, and call it, rather than having the same (sometimes incorrect) code copied all over the place.
1.5	30-May-2001	mrg	use _KERNEL_OPT.
1.4	09-Apr-2001	jdolecek	Change the first arg to fileops fo_stat routine to struct file *, adjust callers and appropriate routines to cope. This makes fo_stat more consistent with rest of fileops routines and also makes the fo_stat match FreeBSD as an added bonus. Discussed with Luke Mewburn on tech-kern@.
1.3	09-Apr-2001	jdolecek	Call file descriptor stat function via (*fp->f_ops->fo_stat) instead of a switch statement and explicit call. Sprinkle some FILE_USE()/FILE_UNUSE() as appropriate.
1.2	08-Apr-2001	ross	Fix soo_stat() calls for the new parameter, even if the direct call is now obsolete, so that kernels will at least compile. I guess it was too much trouble to change all 10 call sites, or perhaps, these days, only things that build on i386 are important. Maybe it's the full moon tonight.

1.53.4.2	14-May-2008	wrstuden	Per discussion with ad, remove most of the #include <sys/sa.h> lines as they were including sa.h just for the type(s) needed for syscallargs.h. Instead, create a new file, sys/satypes.h, which contains just the types needed for syscallargs.h. Yes, there's only one now, but that may change and it's probably more likely to change if it'd be difficult to handle. :-) Per discussion with matt at n dot o, add an include of satypes.h to sigtypes.h. Upcall handlers are kinda signal handlers, and signalling is the header file that's already included for syscallargs.h that closest matches SA. This shaves about 3000 lines off of the diff of the branch relative to the base. That also represents about 18% of the total before this checkin. I think this reduction is very good thing.
1.53.4.1	10-May-2008	wrstuden	Initial checkin of re-adding SA. Everything except kern_sa.c compiles in GENERIC for i386. This is still a work-in-progress, but this checkin covers most of the mechanical work (changing signalling to be able to accomidate SA's process-wide signalling and re-adding includes of sys/sa.h and savar.h). Subsequent changes will be much more interesting. Also, kern_sa.c has received partial cleanup. There's still more to do, though.

1.103	17-May-2019	msaitoh	branches: 1.103.2; The max subtype of the ifmedia word is 31. It's too small for Ethernet now. We currently use use it up to 30. We should extend the limit to be able to use more than 10Gbps speeds. Our ifmedia(4) is inconvenience and have some problem so we should redesign the interface, but it's too late for netbsd-9 to do it. So, we keep the data structure size and modify the structure a bit. The strategy is almost the same as FreeBSD. Many bits of IFM_OMASK for Ethernet have not used, so use some of them for Ethernet's subtype. The differences against FreeBSD are: - We use NetBSD style compat code (i.e. no SIOCGIFXMEDIA). - FreeBSD's IFM_ETH_XTYPE's bit location is from 11 to "14" even though IFM_OMASK is from 8 to "15". We use _IFM_ETH_XTMASK from bit 13 to "15". - FreeBSD changed the meaning of IFM_TYPE_MATCH(). I think we should not do it. We keep it not changing and added new IFM_TYPE_SUBTYPE_MATCH() macro for matching both TYPE and SUBTYPE. - Added up to 400GBASE-SR16. New layout of the media word is as follows (from ifmedia_h): * if_media Options word: * Bits Use * ---- ------- * 0-4 Media subtype MAX SUBTYPE == 255 for ETH and 31 for others * 5-7 Media type * 8-15 Type specific options * 16-18 Mode (for multi-mode devices) * 19 (Reserved for Future Use) * 20-27 Shared (global) options * 28-31 Instance * * 3 2 1 * 1 0 9 8 7 6 5 4 3 2 1 0 9 8 7 6 5 4 3 2 1 0 9 8 7 6 5 4 3 2 1 0 * +-------+---------------+-+-----+---------------+-----+---------+ * \| \| \|R\| \| \| \| \| * \| IMASK \| GMASK \|F\|MMASK+-----+ OMASK \|NMASK\| TMASK \| * \| \| \|U\| \|XTMSK\| \| \| \| * +-------+---------------+-+-----+-----+---------+-----+---------+ * <-----> <---> <---> * IFM_INST() IFM_MODE() IFM_TYPE() * * IFM_SUBTYPE(other than ETH)<-------> * * <---> IFM_SUBTYPE(ETH)<-------> * * * <-------------> <-------------> * IFM_OPTIONS()

Also, different serialisation format means NPF connection/config saving and loading is not compatible with the previous versions either. Thanks to christos@ for extra testing.

1.93	03-Sep-2018	riastradh	Rename min/max -> uimin/uimax for better honesty. These functions are defined on unsigned int. The generic name min/max should not silently truncate to 32 bits on 64-bit systems. This is purely a name change -- no functional change intended. HOWEVER! Some subsystems have #define min(a, b) ((a) < (b) ? (a) : (b)) #define max(a, b) ((a) > (b) ? (a) : (b)) even though our standard name for that is MIN/MAX. Although these may invite multiple evaluation bugs, these do _not_ cause integer truncation. To avoid `fixing' these cases, I first changed the name in libkern, and then compile-tested every file where min/max occurred in order to confirm that it failed -- and thus confirm that nothing shadowed min/max -- before changing it. I have left a handful of bootloaders that are too annoying to compile-test, and some dead code: cobalt ews4800mips hp300 hppa ia64 luna68k vax acorn32/if_ie.c (not included in any kernels) macppc/if_gm.c (superseded by gem(4)) It should be easy to fix the fallout once identified -- this way of doing things fails safe, and the goal here, after all, is to _avoid_ silent integer truncations, not introduce them. Maybe one day we can reintroduce min/max as type-generic things that never silently truncate. But we should avoid doing that for a while, so that existing code has a chance to be detected by the compiler for conversion to uimin/uimax without changing the semantics until we can properly audit it all. (Who knows, maybe in some cases integer truncation is actually intended!)

1.79	31-May-2015	roy	Revert prior change, optionally include PPPOE and SPPP support again. Fix compat_netbsd32 module building by enforcing both.
1.78	31-May-2015	roy	It seems we cannot depend on kernel config in modules, so always compile in PPP(,oE) support.
1.77	31-May-2015	roy	Add support for PPPOEGETPARMS and PPPOESETPARMS.
1.76	31-May-2015	roy	Support SPPPGETAUTHCFG and SPPPSETAUTHCFG.
1.75	31-May-2015	roy	Fixup ifdrv parameter order.

1.73	27-May-2015	matt	Add missing SIOCGDRVSPEC32 Fix SIOCGETSGCNT32
1.72	20-May-2015	matt	Rework ksym defines and includes.
1.71	20-May-2015	matt	Change the ksyms ioctls to more compat_netbsd32 friendly. Use _IOWR ioctls to avoid extra copyouts. With these changes, netstat and vmstat work on mips64eb with the normal N32 userland and a N64 kernel.
1.70	18-May-2015	martin	Implement SIOCIFGCLONERS for netbsd32, so ifconfig -C works.
1.69	24-Jan-2014	bouyer	branches: 1.69.4; 1.69.6; Support WSDISPLAYIO_GETCMAP/WSDISPLAYIO_PUTCMAP. Tested on evbmips/loongson
1.68	24-Jan-2014	manu	Add ATAIOCCOMMAND ioctl form COMPAT_NETBSD32 This enables SMART monitoring by a netbsd32 binary.
1.67	06-Aug-2012	skrll	branches: 1.67.2; 1.67.4; Ensure correct alignment for stack buffers when long != 64-bit, e.g. arm.
1.66	28-May-2012	christos	compat for 80211 ioctls from jmcneill
1.65	11-May-2012	christos	provide clockctl ioctl emulation
1.64	06-Oct-2011	macallan	branches: 1.64.2; 1.64.6; 1.64.8; 1.64.12; 1.64.14; fix pasto, now SIOCS80211NWKEY and SIOCG80211NWKEY actually work
1.63	05-Oct-2011	macallan	forgot SIOCG80211NWKEY32 when adding SIOCS80211NWKEY32
1.62	28-Sep-2011	macallan	support WSDISPLAYIO_GCURSOR and WSDISPLAYIO_SCURSOR
1.61	07-Sep-2011	macallan	support ioctl(POWER_EVENT_RECVDICT) - now powerd turns my gdium's backlight off when the lid is closed
1.60	30-Aug-2011	bouyer	Provide netbsd32 compat for bpf. Beside the ioctls, the structure returned to userland by read(2) also needs to be converted. For this, the bpf descriptor is flagged as compat32 (or not) in the open and ioctl functions (where the user process's pid is also updated in the descriptor). When the bpf buffer is filled in, the 32bits or native header is used depending on the information stored in the descriptor. This won't work if a 64bit binary does the open and ioctls, and then exec a 32bit program which will do the read. But this is very unlikely to happen in real life ... Tested on i386 and loongson; with these changes my loongson can run dhclient and tcpdump with a n32 userland.
1.59	30-Aug-2011	macallan	support SIOCG80211NWKEY
1.58	30-Aug-2011	macallan	add WSDISPLAYIO_ADDSCREEN
1.57	27-Aug-2011	bouyer	translate WDOGIOC_GWDOGS
1.56	04-Apr-2011	ahoka	remove FLASH_GET_INFO compat as it is no longer using size_t
1.55	19-Mar-2011	cliff	compat/netbsd32 ioctl support for FLASH_GET_INFO
1.54	01-Feb-2011	matt	Define 32bit version of SIOC[GS]IFADDRPREF32. We wouldn't need this to if i386 actually aligned a uint64_t on a 64bit boundary but it doesn't. So all that work in sockaddr_storage goes for naught.
1.53	22-Jan-2011	matt	Fix c&p error.
1.52	18-Jan-2011	matt	branches: 1.52.2; Make struct disklabel 8 byte aligned. This increases its size by 4 bytes on IPL32 platforms so add code in sys_ioctl (and netbsd32_ioctl) to deal with the older/smaller diskabel size. This change makes disklabel the same for both IPL32 and LP64 platforms.
1.51	24-Sep-2010	njoly	branches: 1.51.2; Add support for envsys(4) version 2 ioctls.
1.50	19-Sep-2010	mrg	add (runtime untested) support for AUDIO_WSEEK.
1.49	19-Sep-2010	mrg	add support for the netbsd 5.0 versions of the VND* ioctls.
1.48	19-Sep-2010	mrg	support VND* ioctls.
1.47	23-Apr-2010	rmind	Replace M_IOV and some malloc(9)s with kmem(9), and while there: - Fix invalid free (M_TEMP vs M_IOV) in do_sys_recvmsg(), spotted by jakllsch@. Also, same fix in osf1_sys_sendmsg_xopen(). - Fix attempt to free non-allocated memory in error path in netbsd32___getfh30(). - Plug a memory leak in compat_43_netbsd32_orecvmsg().
1.46	11-Dec-2009	njoly	branches: 1.46.2; 1.46.4; In netbsd32_from_{ifreq,oifreq}(), use the compat structure size for memcpy. From mrg.
1.45	10-Dec-2009	njoly	Kill debug printf.
1.44	10-Dec-2009	njoly	Make netbsd32_from_{ifreq,oifreq}() copy the whole structure, not only the interface name. Finally fix my own PR/39424. ok by christos.
1.43	09-Dec-2009	christos	Add netbsd32_oifreq and fix issue in copying the interface name. With this patch OSIOC{G,S}IFFLAGS is supposed to work, but unfortunately getifaddrs seems to be the next problem getting the 4.99.x i386 ifconfig working on an amd64 current machine.
1.42	24-May-2009	ad	More changes to improve kern_descrip.c. - Avoid atomics in more places. - Remove the per-descriptor mutex, and just use filedesc_t::fd_lock. It was only being used to synchronize close, and in any case we needed to take fd_lock to free the descriptor slot. - Optimize certain paths for the <NDFDFILE case. - Sprinkle more comments and assertions. - Cache more stuff in filedesc_t. - Fix numerous minor bugs spotted along the way. - Restructure how the open files array is maintained, for clarity and so that we can eliminate the membar_consumer() call in fd_getfile(). This is mostly syntactic sugar; the main functional change is that fd_nfiles now lives alongside the open file array. Some measurements with libmicro: - simple file syscalls are like close() are between 1 to 10% faster. - some nice improvements, e.g. poll(1000) which is ~50% faster.
1.41	02-Jul-2008	matt	branches: 1.41.10; 1.41.12; Change {ff,fd}_exclose and ff_allocated to bool. Change exclose arg to fd_dup to bool. Switch assignments from 1/0 to true/false. This make alpha kernels compile. Bump kern to 4.99.69 since structure changed.
1.40	23-Jun-2008	njoly	Update compat netbsd32 SIOCGIFCONF ioctls definitions to follow native ones.
1.39	29-May-2008	mrg	branches: 1.39.2; remove clause #3 from my license where there are no other copyright holders involved.
1.38	21-Mar-2008	ad	branches: 1.38.2; 1.38.4; 1.38.6; Catch up with descriptor handling changes. See kern_descrip.c revision 1.173 for details.
1.37	20-Dec-2007	dsl	branches: 1.37.6; Convert all the system call entry points from: int foo(struct lwp l, void v, register_t retval) to: int foo(struct lwp l, const struct foo_args uap, register_t retval) Fixup compat code to not write into 'uap' and (in some cases) to actually pass a correctly formatted 'uap' structure with the right name to the next routine. A few 'compat' routines that just call standard ones have been deleted. All the 'compat' code compiles (along with the kernels required to test build it). 98% done by automated scripts.
1.36	08-Dec-2007	dsl	branches: 1.36.4; ANSIfy most of the function definitions in sys/compat (but not ndis). All by the magic of sed ...
1.35	15-Aug-2007	ad	branches: 1.35.2; 1.35.10; Changes to make ktrace LKM friendly and reduce ifdef KTRACE. Proposed on tech-kern.
1.34	30-May-2007	christos	branches: 1.34.2; 1.34.6; make this compile again XXX: The ioctls will need to be fixed.
1.33	20-Mar-2007	njoly	Add ktrace I/O support to netbsd32_ioctl() syscall. Reviewed by cube.
1.32	18-Mar-2007	dsl	Change all the NETBSD32PTR64(SCARG(uap, xxx))) to SCARG_P32(uap, xxx).
1.31	16-Mar-2007	dsl	remove all the double (and triple) casts used to convert 32bit userspace pointers to and from 64bit kernel pointers. Instead use the defines NETBSD32PTR64(p32) to read a 32bit pointer and (the new) NETBSD32PTR32(p32,p64) to write a 32bit pointer throughout. The 32bit pointer is now a struct to enforce the above. amd64 (with linux emul) and sparc64 will both compile (when the arch stuff goes in soon), and amd64 still runs some i386 binaries.
1.30	04-Mar-2007	christos	branches: 1.30.2; 1.30.4; 1.30.6; fix fallout from caddr_t changes.
1.29	04-Mar-2007	christos	Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.
1.28	09-Feb-2007	ad	branches: 1.28.2; Merge newlock2 to head.
1.27	29-Jan-2007	hubertf	Remove more duplicate headers. Patch by Slava Semushin <slava.semushin@gmail.com> Again, this was tested by comparing obj files from a pristine and a patched source tree against an i386/ALL kernel, and also for src/sbin/fsck_ffs, src/sbin/fsdb and src/usr.sbin/makefs. Only changes in assert() line numbers were detected in 'objdump -d' output.

1.22	15-Jan-2004	mrg	branches: 1.22.8; 1.22.10; begin to implement some ifreq ioctls... long long way to go.
1.21	21-Sep-2003	jdolecek	cleanup & uniform descriptor owner handling: * introduce fsetown(), fgetown(), fownsignal() - this sets/retrieves/signals the owner of descriptor, according to appropriate sematics of TIOCSPGRP/FIOSETOWN/SIOCSPGRP/TIOCGPGRP/FIOGETOWN/SIOCGPGRP ioctl; use these routines instead of custom code where appropriate * make every place handling TIOCSPGRP/TIOCGPGRP handle also FIOSETOWN/FIOGETOWN properly, and remove the translation of FIO[SG]OWN to TIOC[SG]PGRP in sys_ioctl() & sys_fcntl() * also remove the socket-specific hack in sys_ioctl()/sys_fcntl() and pass the ioctls down to soo_ioctl() as any other ioctl change discussed on tech-kern@
1.20	29-Jun-2003	fvdl	branches: 1.20.2; Back out the lwp/ktrace changes. They contained a lot of colateral damage, and need to be examined and discussed more.
1.19	29-Jun-2003	martin	struct proc * -> struct lwp *
1.18	12-Apr-2003	christos	get rid of the ASYNCMAP ioctls
1.17	24-Jan-2003	fvdl	Bump daddr_t to 64 bits. Replace it with int32_t in all places where it was used on-disk, so that on-disk formats remain the same. Remove ufs_daddr_t and ufs_lbn_t for the time being.
1.16	18-Jan-2003	thorpej	Merge the nathanw_sa branch.
1.15	23-Oct-2002	scw	In preparation for COMPAT_NETBSD32 on SH-5: - The MD netbsd32_machdep.h header now defines the 32-bit pointer type instead of using u_int32_t everywhere, - The MD netbsd32_machdep.h header now defines a macro (at least on current implementations) which converts a 32-bit pointer to its 64-bit equivalent, - Change the MI code to utilise the above two items in all the right places, - Implement netbsd32___sigaction_sigtramp(). Tested on Sparc64 by Matt Green.
1.14	03-Jan-2002	mrg	move sparc specific ioctl handling (fb & openprom) into arch/sparc64.
1.13	13-Nov-2001	lukem	add RCSIDs (including regeneration of files as appropriate)

1.11	25-Aug-2001	mrg	branches: 1.11.2; update copyright notices.
1.10	19-Jun-2001	fvdl	branches: 1.10.2; Some of this was sparc-specific, so ifdef __sparc__ it (XXX). Also, change the alignment of one structure with an MD ifdef. Should be moved into the netbsd32_machdep parts.
1.9	14-Jun-2001	thorpej	Fix a partial construction problem that can cause race conditions between creation of a file descriptor and close(2) when using kernel assisted threads. What we do is stick descriptors in the table, but mark them as "larval". This causes essentially everything to treat it as a non-existent descriptor, except for fdalloc(), which sees a filled slot so that it won't (incorrectly) allocate it again. When a descriptor is fully constructed, the code that has constructed it marks it as "mature" (which actually clears the "larval" flag), and things continue to work as normal. While here, gather all the code that gets a descriptor from the table into a fd_getfile() function, and call it, rather than having the same (sometimes incorrect) code copied all over the place.
1.8	05-Dec-2000	eeh	branches: 1.8.2; Fix uninitialized pointer bug.
1.7	19-Aug-2000	eeh	Fix netbsd32_ioctls.
1.6	09-Jul-2000	mrg	- massive warning fix fest. - fix pread/pwrite return values (plus some other syscalls that looked similarly broken). - prototypes and clean up for netbsd32_ioctl.c now getpw*() works under compat32!
1.5	30-Dec-1999	eeh	branches: 1.5.4; Update to 32-bit compatibility routines.
1.4	11-Oct-1999	eeh	branches: 1.4.2; Add netbsd32_compat_14.c Rename everything from compat_netbsd32 -> netbsd32 so we don't have silly names like compat_14_compat_netbsd32_sys_shmctl().
1.3	25-Mar-1999	mrg	branches: 1.3.8; SPARC32->NETBSD32
1.2	25-Mar-1999	mrg	move sparc32 to netbsd32; split out MD part (signal handling) (mostly via repository copy, rename and perl -pi :-)

1.38.6.2	14-May-2008	wrstuden	Per discussion with ad, remove most of the #include <sys/sa.h> lines as they were including sa.h just for the type(s) needed for syscallargs.h. Instead, create a new file, sys/satypes.h, which contains just the types needed for syscallargs.h. Yes, there's only one now, but that may change and it's probably more likely to change if it'd be difficult to handle. :-) Per discussion with matt at n dot o, add an include of satypes.h to sigtypes.h. Upcall handlers are kinda signal handlers, and signalling is the header file that's already included for syscallargs.h that closest matches SA. This shaves about 3000 lines off of the diff of the branch relative to the base. That also represents about 18% of the total before this checkin. I think this reduction is very good thing.
1.38.6.1	10-May-2008	wrstuden	Initial checkin of re-adding SA. Everything except kern_sa.c compiles in GENERIC for i386. This is still a work-in-progress, but this checkin covers most of the mechanical work (changing signalling to be able to accomidate SA's process-wide signalling and re-adding includes of sys/sa.h and savar.h). Subsequent changes will be much more interesting. Also, kern_sa.c has received partial cleanup. There's still more to do, though.

Exceptions: when fd_refcnt <= 1, or when holding fd_lock. While here: - Restore KASSERT(mutex_owned(&fdp->fd_lock)) in fd_unused. => This is used only in fd_close and fd_abort, where it holds. - Move bounds check assertion in fd_putfile to where it matters. - Store fd_dt with atomic_store_release. - Move load of fd_dt under lock in knote_fdclose. - Omit membar_consumer in fdesc_readdir. => atomic_load_consume serves the same purpose now. => Was needed only on alpha anyway. Load struct fdfile::ff_file with atomic_load_consume. Exceptions: when we're only testing whether it's there, not about to dereference it. Note: We do not use atomic_store_release to set it because the preceding mutex_exit should be enough. (That said, it's not clear the mutex_enter/exit is needed unless refcnt > 0 already, in which case maybe it would be a win to switch from the membar implied by mutex_enter to the membar implied by atomic_store_release -- which I would generally expect to be much cheaper. And a little clearer without a long comment.) kern_descrip.c: Fix membars around reference count decrement. In general, the `last one out hit the lights' style of reference counting (as opposed to the `whoever's destroying must wait for pending users to finish' style) requires memory barriers like so: ... usage of resources associated with object ... membar_release(); if (atomic_dec_uint_nv(&obj->refcnt) != 0) return; membar_acquire(); ... freeing of resources associated with object ... This way, all usage happens-before all freeing. This fixes several errors: - fd_close failed to ensure whatever its caller did would happen-before the freeing, in the case where another thread is concurrently trying to close the fd (ff->ff_file == NULL). Fix: Add membar_release before atomic_dec_uint(&ff->ff_refcnt) in that branch. - fd_close failed to ensure all loads its caller had issued will have happened-before the freeing, in the case where the fd is still in use by another thread (fdp->fd_refcnt > 1 and ff->ff_refcnt-- > 0). Fix: Change membar_producer to membar_release before atomic_dec_uint(&ff->ff_refcnt). - fd_close failed to ensure that any usage of fp by other callers would happen-before any freeing it does. Fix: Add membar_acquire after atomic_dec_uint_nv(&ff->ff_refcnt). - fd_free failed to ensure that any usage of fdp by other callers would happen-before any freeing it does. Fix: Add membar_acquire after atomic_dec_uint_nv(&fdp->fd_refcnt). While here, change membar_exit -> membar_release. No semantic change, just updating away from the legacy API.

1.67	17-May-2019	msaitoh	The max subtype of the ifmedia word is 31. It's too small for Ethernet now. We currently use use it up to 30. We should extend the limit to be able to use more than 10Gbps speeds. Our ifmedia(4) is inconvenience and have some problem so we should redesign the interface, but it's too late for netbsd-9 to do it. So, we keep the data structure size and modify the structure a bit. The strategy is almost the same as FreeBSD. Many bits of IFM_OMASK for Ethernet have not used, so use some of them for Ethernet's subtype. The differences against FreeBSD are: - We use NetBSD style compat code (i.e. no SIOCGIFXMEDIA). - FreeBSD's IFM_ETH_XTYPE's bit location is from 11 to "14" even though IFM_OMASK is from 8 to "15". We use _IFM_ETH_XTMASK from bit 13 to "15". - FreeBSD changed the meaning of IFM_TYPE_MATCH(). I think we should not do it. We keep it not changing and added new IFM_TYPE_SUBTYPE_MATCH() macro for matching both TYPE and SUBTYPE. - Added up to 400GBASE-SR16. New layout of the media word is as follows (from ifmedia_h): * if_media Options word: * Bits Use * ---- ------- * 0-4 Media subtype MAX SUBTYPE == 255 for ETH and 31 for others * 5-7 Media type * 8-15 Type specific options * 16-18 Mode (for multi-mode devices) * 19 (Reserved for Future Use) * 20-27 Shared (global) options * 28-31 Instance * * 3 2 1 * 1 0 9 8 7 6 5 4 3 2 1 0 9 8 7 6 5 4 3 2 1 0 9 8 7 6 5 4 3 2 1 0 * +-------+---------------+-+-----+---------------+-----+---------+ * \| \| \|R\| \| \| \| \| * \| IMASK \| GMASK \|F\|MMASK+-----+ OMASK \|NMASK\| TMASK \| * \| \| \|U\| \|XTMSK\| \| \| \| * +-------+---------------+-+-----+-----+---------+-----+---------+ * <-----> <---> <---> * IFM_INST() IFM_MODE() IFM_TYPE() * * IFM_SUBTYPE(other than ETH)<-------> * * <---> IFM_SUBTYPE(ETH)<-------> * * * <-------------> <-------------> * IFM_OPTIONS()

1.64	29-Sep-2018	rmind	NPF: Major rework -- migrate NPF to the libnv library. - This conversion significantly simplifies the code and moves NPF to a binary serialisation format (replacing the XML-like format). - Fix some memory/reference leaks and possibly use-after-free bugs. - Bump NPF_VERSION as this change makes libnpf incompatible with the previous versions. Also, different serialisation format means NPF connection/config saving and loading is not compatible with the previous versions either. Thanks to christos@ for extra testing.

1.39	30-Aug-2011	bouyer	Provide netbsd32 compat for bpf. Beside the ioctls, the structure returned to userland by read(2) also needs to be converted. For this, the bpf descriptor is flagged as compat32 (or not) in the open and ioctl functions (where the user process's pid is also updated in the descriptor). When the bpf buffer is filled in, the 32bits or native header is used depending on the information stored in the descriptor. This won't work if a 64bit binary does the open and ioctls, and then exec a 32bit program which will do the read. But this is very unlikely to happen in real life ... Tested on i386 and loongson; with these changes my loongson can run dhclient and tcpdump with a n32 userland.

The 32bit pointer is now a struct to enforce the above. amd64 (with linux emul) and sparc64 will both compile (when the arch stuff goes in soon), and amd64 still runs some i386 binaries.

1.14	29-Jun-2003	fvdl	branches: 1.14.2; Back out the lwp/ktrace changes. They contained a lot of colateral damage, and need to be examined and discussed more.
1.13	29-Jun-2003	martin	struct proc * -> struct lwp *
1.12	12-Apr-2003	christos	get rid of the ASYNCMAP ioctls
1.11	24-Jan-2003	fvdl	Bump daddr_t to 64 bits. Replace it with int32_t in all places where it was used on-disk, so that on-disk formats remain the same. Remove ufs_daddr_t and ufs_lbn_t for the time being.
1.10	23-Oct-2002	scw	In preparation for COMPAT_NETBSD32 on SH-5: - The MD netbsd32_machdep.h header now defines the 32-bit pointer type instead of using u_int32_t everywhere, - The MD netbsd32_machdep.h header now defines a macro (at least on current implementations) which converts a 32-bit pointer to its 64-bit equivalent, - Change the MI code to utilise the above two items in all the right places, - Implement netbsd32___sigaction_sigtramp(). Tested on Sparc64 by Matt Green.

1.14.12.2	14-May-2008	wrstuden	Per discussion with ad, remove most of the #include <sys/sa.h> lines as they were including sa.h just for the type(s) needed for syscallargs.h. Instead, create a new file, sys/satypes.h, which contains just the types needed for syscallargs.h. Yes, there's only one now, but that may change and it's probably more likely to change if it'd be difficult to handle. :-) Per discussion with matt at n dot o, add an include of satypes.h to sigtypes.h. Upcall handlers are kinda signal handlers, and signalling is the header file that's already included for syscallargs.h that closest matches SA. This shaves about 3000 lines off of the diff of the branch relative to the base. That also represents about 18% of the total before this checkin. I think this reduction is very good thing.
1.14.12.1	10-May-2008	wrstuden	Initial checkin of re-adding SA. Everything except kern_sa.c compiles in GENERIC for i386. This is still a work-in-progress, but this checkin covers most of the mechanical work (changing signalling to be able to accomidate SA's process-wide signalling and re-adding includes of sys/sa.h and savar.h). Subsequent changes will be much more interesting. Also, kern_sa.c has received partial cleanup. There's still more to do, though.

1.6	05-Sep-2020	riastradh	Round of uvm.h cleanup. The poorly named uvm.h is generally supposed to be for uvm-internal users only. - Narrow it to files that actually need it -- mostly files that need to query whether curlwp is the pagedaemon, which should maybe be exposed by an external header. - Use uvm_extern.h where feasible and uvm_*.h for things not exposed by it. We should split up uvm_extern.h but this will serve for now to reduce the uvm.h dependencies. - Use uvm_stat.h and #ifdef UVMHIST uvm.h for files that use UVMHIST(ubchist), since ubchist is declared in uvm.h but the reference evaporates if UVMHIST is not defined, so we reduce header file dependencies. - Make uvm_device.h and uvm_swap.h independently includable while here. ok chs@
1.5	12-Dec-2019	pgoyette	Rather than keeping a separate mutex, condvar, and pserialize for each module hook, we can share a common set of synchronization structures. This cuts the amount of cacheline_aligned data for these structures by 50%. Note that we still have a per-hook localcount, since we need to count individual references. As discussed with riastradh@ Welcome to 9.99.22 !
1.4	01-Mar-2019	pgoyette	branches: 1.4.4; Rename the MODULE__HOOK() macros to MODULE_HOOK_() as briefly discussed on irc. NFCI intended. Ride the earlier kernel bump - it;s getting crowded.
1.3	29-Jan-2019	pgoyette	Normalize all the compat hooks' names to the form <subsystem>_<function>_<version>_hook NFCI XXX Note that although this introduces a change in the kernel-to- XXX module interface, we are NOT bumping the kernel version number. XXX We will bump the version number once the interface stabilizes.
1.2	27-Jan-2019	pgoyette	Merge the [pgoyette-compat] branch
1.1	23-Sep-2018	pgoyette	branches: 1.1.2; file netbsd32_kern_proc.c was initially added on branch pgoyette-compat.
1.1.2.8	23-Jan-2019	pgoyette	Convert the macros for setting and unsetting a hook to generate in-line code rather than using an intermediary hook##set routine. Hooks are set and unset only in one place, so the intermediary routine provides no benefit. IMHO using the macro at the point- of-call is more readable than using it elsewhere in the code and then calling the generated intermediary routine (for which you won't even find its declaration or definition unless you remember to search for the HOOK_SET macro instead). NFC intended, will verify with a bulk build and an atf test run.
1.1.2.7	22-Jan-2019	pgoyette	Convert the MODULE_{,VOID_}HOOK_CALL macros to do everything in-line rather than defining an intermediate hook##call function. Almost all of the hooks are called only once, and although we lose the ability of doing things like if (MODULE_HOOK_CALL(...) == 0) ... we simplify things quite a bit. With this change, we no longer need to have both declaration and definition macros, and the definition no longer needs to have both prototype argument list and a "real" argument list. FWIW, the above if now needs to written as int ret; MODULE_HOOK_CALL(..., ret); if (ret == 0) ... with appropriate use of braces {}.
1.1.2.6	14-Jan-2019	pgoyette	Create a variant of the HOOK macros that handles hook routines of type void, and use them where appropriate.
1.1.2.5	13-Jan-2019	pgoyette	Remove the HOOK2 versions of the MODULE_HOOK macros. There were only a few uses, and using them led to some lack of clarity in the code. Instead, we now use two separate hooks, with names that make it clear(er) what we're doing. This also positions us to start unraveling some of the rtsock_50 mess, which will need (at least) five hooks.
1.1.2.4	23-Sep-2018	pgoyette	Use a .h file to define the xxx_{init,fini} routines, and include the compat_stub.h header to get the definition of the kern_proc_32 hook.
1.1.2.3	23-Sep-2018	pgoyette	Use the proper test: _RUMPKERNEL vs _RUMP_KERNEL

1.2	16-Jan-2004	mrg	clean up a little: - delete ktrsyscall32() - add a check #ifdef _LP64 to do the conversion if P_32 is set to the standard ktrsyscall() - add a couple of similar _LP64/P_32 checks to the systrace code. this should get systrace working for 32 bit apps as well as complete ktrace support for "trace_enter/trace_exit" using platforms such as amd64. XXX: systrace isn't supported on sparc64 currently... (it doesn't use trace_enter/trace_exit, or have it's own calls to systrace_xxx()...)
1.1	15-Jan-2004	mrg	add a copy of the ktrsyscall() entry point for 32 bit emulated calls. the main purpose of this function is to adjust the "argsize" value of the ktrace syscall record, otherwise userland will see N/2 (rounded down) arguments instead of N.
1.23	14-Jan-2021	simonb	Handle rev 1.62 of kern/sys_lwp.c make _lwp_park return the remaining time to sleep in the "ts" argument if it is a relative timestamp, as discussed in tech-kern. for compat32. Thanks skrll@ for some cleanup tips.
1.22	29-Jan-2020	ad	branches: 1.22.6; - Track LWPs in a per-process radixtree. It uses no extra memory in the single threaded case. Replace scans of p->p_lwps with lookups in the tree. Find free LIDs for new LWPs in the tree. Replace the hashed sleep queues for park/unpark with lookups in the tree under cover of a RW lock. - lwp_wait(): if waiting on a specific LWP, find the LWP via tree lookup and return EINVAL if it's detached, not ESRCH. - Group the locks in struct proc at the end of the struct in their own cache line. - Add some comments.
1.21	26-Jan-2020	ad	Correction to previous: don't leak newuc if copyout() fails.
1.20	25-Jan-2020	ad	- Fix a race between the kernel and libpthread, where a new thread can start life without its self->pt_lid being filled in. - Fix an error path in _lwp_create(). If the new LID can't be copied out, then get rid of the new LWP (i.e. either succeed or fail, not both). - Mark l_dopreempt and l_nopreempt volatile in struct lwp.
1.19	21-Apr-2017	christos	branches: 1.19.12; 1.19.18; - Propagate the signal mask from the ucontext_t to the newly created thread as specified by _lwp_create(2) - Reset the signal stack for threads created with _lwp_create(2)

1.14	20-Jul-2012	christos	branches: 1.14.2; always allocate a full ucontext structure so that we don't corrupt memory. XXX: needs pullup to 6?
1.13	21-May-2012	martin	Calling _lwp_create() with a bogus ucontext could trigger a kernel assertion failure (and thus a crash in DIAGNOSTIC kernels). Independently discovered by YAMAMOTO Takashi and Joel Sing. To avoid this, introduce a cpu_mcontext_validate() function and move all sanity checks from cpu_setmcontext() there. Also untangle the netbsd32 compat mess slightly and add a cpu_mcontext32_validate() cousin there. Add an exhaustive atf test case, based partly on code from Joel Sing. Should finally fix the remaining open part of PR kern/43903.
1.12	05-Feb-2011	yamt	branches: 1.12.4; 1.12.8; 1.12.10; netbsd32__lwp_create: add a comment and CTASSERT.

1.9	20-Dec-2007	dsl	branches: 1.9.6; 1.9.8; 1.9.10; Convert all the system call entry points from: int foo(struct lwp l, void v, register_t retval) to: int foo(struct lwp l, const struct foo_args uap, register_t retval) Fixup compat code to not write into 'uap' and (in some cases) to actually pass a correctly formatted 'uap' structure with the right name to the next routine. A few 'compat' routines that just call standard ones have been deleted. All the 'compat' code compiles (along with the kernels required to test build it). 98% done by automated scripts.
1.8	07-Dec-2007	ad	branches: 1.8.4; Add: _lwp_setname, _lwp_getname, _lwp_ctl.
1.7	10-Sep-2007	cube	branches: 1.7.6; 1.7.8; Some more licence clean up.
1.6	07-Aug-2007	ad	branches: 1.6.2; - Fix a bug with _lwp_park() where if the computed wakeup time was under 1 microsecond into the future, the thread could enter an untimed sleep. - Change the signature of _lwp_park() to accept an lwpid_t and second hint pointer, but do so in a way that remains compatible with older pthread libraries. This can be used to wake another thread before the calling thread goes asleep, saving at least one syscall + involuntary context switch. This turns out to be a fairly large win on the condvar benchmarks that I have tried. - Mark some more syscalls MP safe.
1.5	03-Jun-2007	dsl	branches: 1.5.2; 1.5.6; Split sys__lwp_park() so that the compat/netbsd32 code can copyin and convert its timeout then call the standard function.
1.4	18-Mar-2007	dsl	Change all the NETBSD32PTR64(SCARG(uap, xxx))) to SCARG_P32(uap, xxx).
1.3	16-Mar-2007	dsl	remove all the double (and triple) casts used to convert 32bit userspace pointers to and from 64bit kernel pointers. Instead use the defines NETBSD32PTR64(p32) to read a 32bit pointer and (the new) NETBSD32PTR32(p32,p64) to write a 32bit pointer throughout. The 32bit pointer is now a struct to enforce the above. amd64 (with linux emul) and sparc64 will both compile (when the arch stuff goes in soon), and amd64 still runs some i386 binaries.
1.2	04-Mar-2007	christos	branches: 1.2.2; 1.2.4; 1.2.6; Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.
1.1	18-Feb-2007	cube	branches: 1.1.2; 1.1.6; Add missing lwp syscalls. Put them all together into a new file, netbsd32_lwp.c, and remove remaining traces of SA. This still needs some MD (and possibly MI, depending on the chosen solution) changes to actually work.

1.21	15-Mar-2020	pgoyette	Use SYSCTL_SETUP mechanism to establish our sysctl tree, rather than using explicit calls to netbsd32_sysctl_{init,fini}()
1.20	09-Mar-2020	pgoyette	Rework previous, so that the real syscall code is not invoked from within the module_hook code. Otherwise, if the syscall just happens to be exit() we will exit while still holding a reference to the hook's localcount, and nothing will ever release that reference. Attempts to manually unload the module will hang indefinitely, as will modstat(8). XXX pullup-9
1.19	09-Mar-2020	pgoyette	If a syscall requires a module to be autoloaded, the initial invocation of that syscall will return ERESTART. For amd64's netbsd32_syscall() that means we need to back up the PC saved in the trap frame so we can re-issue the syscall instruction. For "normal" syscall traps, we saved the instruction length in the trap frame, but this was missing for the oosyscall/lcall path. Since the PC was not backed up, the kernel-only value ERESTART was returned to userland, causing all sort of grief for old compat_netbsd32 executables! XXX Pullup-9

1.13.18.2	08-Apr-2020	martin	Merge changes from current as of 20200406
1.13.18.1	10-Jun-2019	christos	Sync with HEAD
1.13.16.19	25-Jan-2019	pgoyette	Move the netbsd32_machine32_hook into the main kernel with most of the other hooks. Although this hook might better belong in compat/netbsd32/ code, there are some machines without a netbsd32 module (for example, i386 and sgimips) which still have consumers/users of this hook. :(
1.13.16.18	24-Jan-2019	pgoyette	Rework placement of the new netbsd32_machine32_hook
1.13.16.17	26-Dec-2018	pgoyette	Sync with HEAD, resolve a few conflicts
1.13.16.16	23-Sep-2018	pgoyette	Use a .h file to define the xxx_{init,fini} routines, and include the compat_stub.h header to get the definition of the kern_proc_32 hook.
1.13.16.15	23-Sep-2018	pgoyette	The kern_proc_32 hook is in the main kernel, so don't make another one here.
1.13.16.14	23-Sep-2018	pgoyette	More work on kern_proc_32
1.13.16.13	18-Sep-2018	pgoyette	The COMPAT_HOOK macros were renamed to MODULE_HOOK, adjust all callers
1.13.16.12	18-Sep-2018	pgoyette	Use the MP-safe compat hooks for netbsd32_compat_80.c's modctl
1.13.16.11	14-Sep-2018	pgoyette	OMG it builds! Finish rearranging the amd64 MD compat_netbsd32 code. XXX Other architectures will be dealt with later.
1.13.16.10	14-Sep-2018	pgoyette	Work in progress - get the arch-specific netbsd32_machdep.c code to build as a module. XXX Doesn't work when the code is built-in to the kernel.
1.13.16.9	14-Sep-2018	pgoyette	Require coredump since netbsd32 module will be built with COREDUMP enabled.
1.13.16.8	13-Sep-2018	pgoyette	More clean-up of module dependencies
1.13.16.7	13-Sep-2018	pgoyette	Now that compat_netbsd32 is no longer monolithic, it no longer requires compat_09 (and all higher) compat code. Adjust the requirements list accordingly.
1.13.16.6	11-Sep-2018	pgoyette	Move netbsd32_rndpseudo_50.c out of the main netbsd32 module and into the module that handles netbsd32_50 compatability.
1.13.16.5	11-Sep-2018	pgoyette	Install the syscalls into the netbsd32 table, not the default/native table.
1.13.16.4	10-Sep-2018	pgoyette	More work on splitting the compat_netbsd32 module
1.13.16.3	09-Sep-2018	pgoyette	The compat_netbsd32 module requires compat_09 and above. Since we removed the alias names, we need to explicitly refer to the oldest non-32 required compat module.
1.13.16.2	21-Mar-2018	pgoyette	Split compat/rndpseudo_50.c into two pieces, one for native compat and a second piece for compat32. Update both modules accordingly.
1.13.16.1	11-Mar-2018	pgoyette	Update module dependencies
1.15.4.4	10-Mar-2020	martin	Pull up following revision(s) (requested by pgoyette in ticket #778): sys/compat/netbsd32/netbsd32_mod.c: revision 1.20 sys/arch/amd64/amd64/trap.c: revision 1.127 Rework previous, so that the real syscall code is not invoked from within the module_hook code. Otherwise, if the syscall just happens to be exit() we will exit while still holding a reference to the hook's localcount, and nothing will ever release that reference. Attempts to manually unload the module will hang indefinitely, as will modstat(8). XXX pullup-9
1.15.4.3	09-Mar-2020	martin	Pull up following revision(s) (requested by pgoyette in ticket #770): sys/compat/netbsd32/netbsd32_mod.c: revision 1.19 If a syscall requires a module to be autoloaded, the initial invocation of that syscall will return ERESTART. For amd64's netbsd32_syscall() that means we need to back up the PC saved in the trap frame so we can re-issue the syscall instruction. For "normal" syscall traps, we saved the instruction length in the trap frame, but this was missing for the oosyscall/lcall path. Since the PC was not backed up, the kernel-only value ERESTART was returned to userland, causing all sort of grief for old compat_netbsd32 executables! XXX Pullup-9
1.15.4.2	09-Mar-2020	martin	Apply patch, requested by pgoyette in ticket #775 to fix fallout from ticket #762: sys/compat/netbsd32/netbsd32_mod.c (patched) Fiy arguments to MODULE_HOOK_SET for the new amd64_oosyscall_hook.
1.15.4.1	08-Mar-2020	martin	Pull up following revision(s) (requested by pgoyette in ticket #762): sys/arch/amd64/amd64/trap.c: revision 1.126 sys/compat/netbsd32/netbsd32_mod.c: revision 1.17 sys/compat/netbsd32/netbsd32_mod.c: revision 1.18 sys/sys/compat_stub.h: revision 1.23 Fix another left-over from last year's [pgoyette-compat] work. This allows recognition of the oosyscall sequence for amd64. Fixes PR kern/55038 XXX pullup-9 - fix indentation. NFCI
1.11	24-May-2022	andvar	s/build-in/built-in/ in comments.
1.10	01-Mar-2019	pgoyette	Rename the MODULE__HOOK() macros to MODULE_HOOK_() as briefly discussed on irc. NFCI intended. Ride the earlier kernel bump - it;s getting crowded.
1.9	31-Jan-2019	christos	remove unused variable
1.8	27-Jan-2019	pgoyette	Merge the [pgoyette-compat] branch
1.7	03-Sep-2018	riastradh	Rename min/max -> uimin/uimax for better honesty. These functions are defined on unsigned int. The generic name min/max should not silently truncate to 32 bits on 64-bit systems. This is purely a name change -- no functional change intended. HOWEVER! Some subsystems have #define min(a, b) ((a) < (b) ? (a) : (b)) #define max(a, b) ((a) > (b) ? (a) : (b)) even though our standard name for that is MIN/MAX. Although these may invite multiple evaluation bugs, these do _not_ cause integer truncation. To avoid `fixing' these cases, I first changed the name in libkern, and then compile-tested every file where min/max occurred in order to confirm that it failed -- and thus confirm that nothing shadowed min/max -- before changing it. I have left a handful of bootloaders that are too annoying to compile-test, and some dead code: cobalt ews4800mips hp300 hppa ia64 luna68k vax acorn32/if_ie.c (not included in any kernels) macppc/if_gm.c (superseded by gem(4)) It should be easy to fix the fallout once identified -- this way of doing things fails safe, and the goal here, after all, is to _avoid_ silent integer truncations, not introduce them. Maybe one day we can reintroduce min/max as type-generic things that never silently truncate. But we should avoid doing that for a while, so that existing code has a chance to be detected by the compiler for conversion to uimin/uimax without changing the semantics until we can properly audit it all. (Who knows, maybe in some cases integer truncation is actually intended!)
1.6	18-Jan-2018	maxv	branches: 1.6.2; 1.6.4; Don't return the address of the kernel modules if the user is not privileged. Discussed on tech-kern@.
1.5	01-Jun-2017	chs	branches: 1.5.8; remove checks for failure after memory allocation calls that cannot fail: kmem_alloc() with KM_SLEEP kmem_zalloc() with KM_SLEEP percpu_alloc() pserialize_create() psref_class_create() all of these paths include an assertion that the allocation has not failed, so callers should not assert that again.
1.4	19-Dec-2015	maxv	Missing field (was here before my change).
1.3	12-Dec-2015	maxv	Put the code in charge of handling MODCTL_STAT (32bit) into a separate function. No functional change.
1.2	21-Jun-2015	msaitoh	branches: 1.2.2; Add missing sys/kauth.h
1.1	20-Jun-2015	martin	Implement modctl, sigqueinfo and mq_*

1.2.2.3	27-Dec-2015	skrll	Sync with HEAD (as of 26th Dec)
1.2.2.2	22-Sep-2015	skrll	Sync with HEAD
1.2.2.1	21-Jun-2015	skrll	file netbsd32_module.c was added on branch nick-nhusb on 2015-09-22 12:05:55 +0000

1.5.8.1	01-Jun-2017	jdolecek	file netbsd32_module.c was added on branch tls-maxphys on 2017-12-03 11:36:56 +0000
1.6.4.1	10-Jun-2019	christos	Sync with HEAD
1.6.2.13	22-Jan-2019	pgoyette	Convert the MODULE_{,VOID_}HOOK_CALL macros to do everything in-line rather than defining an intermediate hook##call function. Almost all of the hooks are called only once, and although we lose the ability of doing things like if (MODULE_HOOK_CALL(...) == 0) ... we simplify things quite a bit. With this change, we no longer need to have both declaration and definition macros, and the definition no longer needs to have both prototype argument list and a "real" argument list. FWIW, the above if now needs to written as int ret; MODULE_HOOK_CALL(..., ret); if (ret == 0) ... with appropriate use of braces {}.
1.6.2.12	18-Jan-2019	pgoyette	Don't restrict hooks to having only int or void types. Pass the hook's type to the various macros, as needed. Allows us to reduce diffs to original in at least one or two places (we no longer have to provide an additional parameter to the hook routine for returning a non-int return value).
1.6.2.11	14-Jan-2019	pgoyette	Create a variant of the HOOK macros that handles hook routines of type void, and use them where appropriate.
1.6.2.10	13-Jan-2019	pgoyette	Remove the HOOK2 versions of the MODULE_HOOK macros. There were only a few uses, and using them led to some lack of clarity in the code. Instead, we now use two separate hooks, with names that make it clear(er) what we're doing. This also positions us to start unraveling some of the rtsock_50 mess, which will need (at least) five hooks.
1.6.2.9	29-Sep-2018	pgoyette	In MODULE_HOOK_CALL_DECL we don't need to provide the actual argument list for calling the hook function, nor do we need to provide the default value (for when the hook has not been set).
1.6.2.8	18-Sep-2018	pgoyette	The COMPAT_HOOK macros were renamed to MODULE_HOOK, adjust all callers
1.6.2.7	18-Sep-2018	pgoyette	Use the MP-safe compat hooks for netbsd32_compat_80.c's modctl
1.6.2.6	14-Sep-2018	pgoyette	Move some extern definitions into netbsd32_netbsd.h rather than having them in the .c files.
1.6.2.5	11-Sep-2018	pgoyette	Install the syscalls into the netbsd32 table, not the default/native table.
1.6.2.4	10-Sep-2018	pgoyette	More work on splitting the compat_netbsd32 module
1.6.2.3	07-Sep-2018	pgoyette	At the request of reviewers, remove the module alias functionality. We will rely only on module names and duplicate-symbol detection to detect module conflicts.
1.6.2.2	06-Sep-2018	pgoyette	Sync with HEAD Resolve a couple of conflicts (result of the uimin/uimax changes)
1.6.2.1	03-Apr-2018	pgoyette	Remove fixed allocation of modules' "required" lists (previously limited to MAXMODDEPS entries). Update the modctl(MODCTL_STAT) syscall to return the required data in a new format, and retain the previous data format in MODCTL_OSTAT. Update the compat_80 and compat_netbsd32 modules as needed.
1.7	27-Jan-2019	pgoyette	Merge the [pgoyette-compat] branch
1.6	01-Dec-2015	pgoyette	branches: 1.6.16; 1.6.18; 1.6.20; Prepare for new compat_netbsd32_mqueue module to be split out of compat_netbsd32. Refactor the COMPAT_50 code related to mqueue, and update the syscall definitions. Remove dependency on mqueue from the compat_netbsd32 module (the new module will gain this dependency).

1.232	19-Jan-2021	simonb	The read/write/send/recv system calls return ssize_t because -1 is returned on error. Therefore we must restrict the lengths of any buffers to NETBSD32_SSIZE_MAX with compat32 to avoid garbage return values. Fixes ATF lib/libc/sys/t_write:write_err.

Update the documentation to reflect this state. Add ATF tests. This is an in-kernel implementation as typically user-space programs use mkfifo(2) directly, however whenever there is need to bypass libc (like in valgrind) then portable POSIX software calls the mknod syscall. Noted on tech-kern@ by Greg Troxel.

1.222	24-Dec-2018	mrg	move mmap(), compat 40 mount(), pipe() and getfh() into their own files as the implementation is non trivial or is compat. mark old mount() properly instead of manually #if'ing ito to ENOSYS.
1.221	24-Dec-2018	mrg	move rlimit and quota code into their own modules. (netbsd32_netbsd.c should have only simple shims. anything more than copying arguments from one args struct to the other should not be placed in this file. still a couple more to move out.)
1.220	24-Dec-2018	mrg	fix style consistency. remove obsolete comments or commented code. NFC.
1.219	24-Dec-2018	mrg	pset_create() takes a pointer so it needs special handling.
1.218	10-Aug-2018	pgoyette	Allow syscall_establish() to install new syscalls when the existing entry-point is either sys_nomodule or sys_nosys. Update the makesyscalls.sh script to create a const array of bits to allow syscall_disestablish() to properly restore the original entry-point. Update all the initializers of struct emul to initialize the pointer to the bit array struct emul. XXX Regen of all files created by makesyscalls.sh will come soon, XXX followed by a kernel version bump (since struct emul is being XXX modified). This commit should address PR kern/45781 and also removes the need for the work-around for that PR in file sys/arch/usermode/modules/syscallemu/syscallemu.c
1.217	31-Jul-2018	rjs	Add getsockopt2().
1.216	06-May-2018	kamil	branches: 1.216.2; Remove an element from struct emul: e_tracesig e_tracesig used to be implemented for Darwin compat. Nowadays the Darwin compatiblity layer is gone and there are no other users. This functionality isn't used where it shall be used in the existing codebase. If we want to emulate debugging interfaces in compat layers we would need to implement that from scratch anyway. We would need to be bug compatible with other OSes too. Proposed on tech-kern@. Welcome to NetBSD 8.99.16! Sponsored by <The NetBSD Foundation>
1.215	15-Mar-2018	christos	Untangle the swapctl compat code mess. Welcome to lucky 13.
1.214	09-Jan-2018	maya	branches: 1.214.2; remove struct emul's e_fault. It used to be used by COMPAT_IRIX for the purpose of overriding uvm_fault (only implemented in MIPS), now removed. Ride 8.99.12 version bump.
1.213	06-Jan-2018	kamil	Revert vadvise(2) removal This system call was used in legacy Lisp code, that was inherited to modern age and still compiled against supported compat layers (e.g. in clisp, oaklisp, Franz Lisp). It used to instruct the kernel about paging policy (G/C aware, flush etc). Newly compiled code (assuming that it will detect vadvise()) will use the libc stub for vadvise(). The headers for this interface are gone. vadvise(2) could be marked as COMPAT_80, but as long as we support ultrix, sunos or aout68k ABI, don't bother with this. Requested by <mrg>
1.212	26-Dec-2017	kamil	Refactor pipe1() and correct a bug in sys_pipe2() (SYS_pipe2) sys_pipe2() returns two integers (values), the 2nd one is a copy of the 2nd file descriptor that lands in fildes[2]. This is a side effect of reusing the code for sys_pipe() (SYS_pipe) and not cleaning it up. The first returned value is (on success) 0. Introduced a small refactoring in pipe1() that it does not operate over retval[], but on an array int[2]. A user sets retval[] for pipe() when desired and needed. This refactoring touches compat code: netbsd32, linux, linux32. Before the changes on NetBSD/amd64: $ ktruss -i ./a.out [...] 15131 1 a.out pipe2(0x7f7fff2e62b8, 0) = 0, 4 [...] After the changes: $ ktruss -i ./a.out [...] 782 1 a.out pipe2(0x7f7fff97e850, 0) = 0 [...] There should not be a visible change for current users.

If you're going to change the name of something, you need to change the name of all the things with the same name, not just a handful, and you should change it to something similar so it still matches the rest of the system rather than just picking an arbitrarily different name. Hi, Joerg. To wit, rename the quotactl "delete" operation to "del", because "delete" is a reserved word in C++ and for some reason Joerg wants to run internal interfaces used only by C code through his C++ compiler. Do not rename it to "remove" instead, because this doesn't match libquota or the rest of the usage throughout the system; and rename all the related identifiers, not just the ones that blew the mind of Joerg's C++ compiler. Because this is not a user-facing API (the only userland consumer sys/quotactl.h is libquota) it is sort of ok to make arbitrary source-incompatible changes; however, by the same token it's completely unnecessary. If it were a user-facing API that someone might have a semi-rational reason to want to run a C++ compiler on, it would be incorrect to change it at this point.

Callers of namei must now create a pathbuf and pass it to NDINIT (instead of a string and a uio_seg), then destroy the pathbuf after the namei session is complete. Update all namei call sites accordingly. Add a pathbuf(9) man page and update namei(9). The pathbuf interface also now appears in a couple of related additional places that were passing string/uio_seg pairs that were later fed into NDINIT. Update other call sites accordingly.

1.138	26-Jan-2008	dsl	Split the return value of sys_lseek() into two 32 bit halves for retval[0/1] in a manner that is endianness independant. Should mean the amd64 will return correct offsets > 2^32 (sparc64 had a special define). Any new netbsd32 ports should work regardless of the endianness.

1.128	29-Sep-2007	dsl	branches: 1.128.2; 1.128.4; Change the way p->p_limit (and hence p->p_rlimit) is locked. Should fix PR/36939 and make the rlimit code MP safe. Posted for comment to tech-kern (non received!) The p_limit field (for a process) is only be changed once (on the first write), and a reference to the old structure is kept (for code paths that have cached the pointer). Only p->p_limit is now locked by p->p_mutex, and since the referenced memory will not go away, is only needed if the pointer is to be changed. The contents of 'struct plimit' are all locked by pl_mutex, except that the code doesn't bother to acquire it for reads (which are basically atomic). Add FORK_SHARELIMIT that causes fork1() to share the limits between parent and child, use it for the IRIX_PR_SULIMIT. Fix borked test for both IRIX_PR_SUMASK and IRIX_PR_SDIR being set.

1.123	22-Apr-2007	dsl	Delete a diagnostic printf and some unused 'stack gap' initialisation.
1.122	22-Apr-2007	dsl	Change the way that emulations locate files within the emulation root to avoid having to allocate space in the 'stackgap' - which is very LWP unfriendly. The additional code for non-emulation namei() is trivial, the reduction for the emulations is massive. The vnode for a processes emulation root is saved in the cwdi structure during process exec. If the emulation root the TRYEMULROOT flag are set, namei() will do an initial search for absolute pathnames in the emulation root, if that fails it will retry from the normal root. ".." at the emulation root will always go to the real root, even in the middle of paths and when expanding symlinks. Absolute symlinks found using absolute paths in the emulation root will be relative to the emulation root (so /usr/lib/xxx.so -> /lib/xxx.so links inside the emulation root don't need changing). If the root of the emulation would be returned (for an emulation lookup), then the real root is returned instead (matching the behaviour of emul_lookup, but being a cheap comparison here) so that programs that scan "../.." looking for the root dircetory don't loop forever. The target for symbolic links is no longer mangled (it used to get the CHECK_ALT_xxx() treatment, so could get /emul/xxx prepended). CHECK_ALT_xxx() are no more. Most of the change is deleting them, and adding TRYEMULROOT to the flags to NDINIT(). A lot of the emulation system call stubs could now be deleted.
1.121	18-Mar-2007	dsl	Change all the NETBSD32PTR64(SCARG(uap, xxx))) to SCARG_P32(uap, xxx).
1.120	16-Mar-2007	dsl	remove all the double (and triple) casts used to convert 32bit userspace pointers to and from 64bit kernel pointers. Instead use the defines NETBSD32PTR64(p32) to read a 32bit pointer and (the new) NETBSD32PTR32(p32,p64) to write a 32bit pointer throughout. The 32bit pointer is now a struct to enforce the above. amd64 (with linux emul) and sparc64 will both compile (when the arch stuff goes in soon), and amd64 still runs some i386 binaries.

1.113	21-Nov-2006	christos	From Nicolas Joly: > It seems that 32bits programs, running under compat_netbsd32, using > setrlimit force all other programs to have their maximum data size > fixed at 3GB, where native 64bits apps used 8GB previously. I tracked this one to the `netbsd32_adjust_limits()' function (called when creating a new process under compat_netbsd32), where data and stack limits are set without checking for shared `p_limit' structure (p_limit->p_refcnt > 1). This explain the side effect where processes have their limits changed when a compat_netbsd32 (or compat_linux32) program is run. The fix is to use `dosetrlimit()' to ensure the needed copy-on-write behaviour for shared structure.

Add a new function pointer to struct emul, pointing at a function that will return the default VM map address. The default function is uvm_map_defaultaddr, which just uses the VM_DEFAULT_ADDRESS macro. This gives emulations control over the default map address, and allows things to be mapped at the right address (in 32bit range) for COMPAT_NETBSD32. * Add code to adjust the data and stack limits when a COMPAT_NETBSD32 or COMPAT_SVR4_32 binary is executed. * Don't use USRSTACK in kern_resource.c, use p_vmspace->vm_minsaddr instead (emulations might have set it differently) * Since this changes struct emul, bump kernel version to 3.99.2 Tested on amd64, compile-tested on sparc64.

1.79	20-Dec-2003	manu	Introduce lwp_emuldata and the associated hooks. No hook is provided for the exec case, as the emulation already has the ability to intercept that with the e_proc_exec hook. It is the responsability of the emulation to take appropriaye action about lwp_emuldata in e_proc_exec. Patch reviewed by Christos.
1.78	05-Dec-2003	jdolecek	back the sigfilter emulation hook change off
1.77	04-Dec-2003	atatat	Dynamic sysctl. Gone are the old kern_sysctl(), cpu_sysctl(), hw_sysctl(), vfs_sysctl(), etc, routines, along with sysctl_int() et al. Now all nodes are registered with the tree, and nodes can be added (or removed) easily, and I/O to and from the tree is handled generically. Since the nodes are registered with the tree, the mapping from name to number (and back again) can now be discovered, instead of having to be hard coded. Adding new nodes to the tree is likewise much simpler -- the new infrastructure handles almost all the work for simple types, and just about anything else can be done with a small helper function. All existing nodes are where they were before (numerically speaking), so all existing consumers of sysctl information should notice no difference. PS - I'm sorry, but there's a distinct lack of documentation at the moment. I'm working on sysctl(3/8/9) right now, and I promise to watch out for buses.
1.76	03-Dec-2003	manu	Add a sigfilter emulation hook. It is used at the beginning of kpsignal2() so that a specific emulation has the oportunity to filter out some signals. if sigfilter returns 0, then no signal is sent by kpsignal2(). There is another place where signals can be generated: trapsignal. Since this function is already an emulation hook, no call to the sigfilter hook was introduced in trapsignal. This is needed to emulate the softsignal feature in COMPAT_DARWIN (signals sent as Mach exception messages)
1.75	26-Sep-2003	christos	Add necessary include file.
1.74	24-Aug-2003	chs	add support for non-executable mappings (where the hardware allows this) and make the stack and heap non-executable by default. the changes fall into two basic catagories: - pmap and trap-handler changes. these are all MD: = alpha: we already track per-page execute permission with the (software) PG_EXEC bit, so just have the trap handler pay attention to it. = i386: use a new GDT segment for %cs for processes that have no executable mappings above a certain threshold (currently the bottom of the stack). track per-page execute permission with the last unused PTE bit. = powerpc/ibm4xx: just use the hardware exec bit. = powerpc/oea: we already track per-page exec bits, but the hardware only implements non-exec mappings at the segment level. so track the number of executable mappings in each segment and turn on the no-exec segment bit iff the count is 0. adjust the trap handler to deal. = sparc (sun4m): fix our use of the hardware protection bits. fix the trap handler to recognize text faults. = sparc64: split the existing unified TSB into data and instruction TSBs, and only load TTEs into the appropriate TSB(s) for the permissions. fix the trap handler to check for execute permission. = not yet implemented: amd64, hppa, sh5 - changes in all the emulations that put a signal trampoline on the stack. instead, we now put the trampoline into a uvm_aobj and map that into the process separately. originally from openbsd, adapted for netbsd by me.

1.68	06-Dec-2002	scw	Avoid strict-alias warnings.
1.67	01-Nov-2002	jdolecek	set struct emul's nsysent to compat SYS_NSYSENT, not SYS_MAXSYSCALL
1.66	23-Oct-2002	scw	In preparation for COMPAT_NETBSD32 on SH-5: - The MD netbsd32_machdep.h header now defines the 32-bit pointer type instead of using u_int32_t everywhere, - The MD netbsd32_machdep.h header now defines a macro (at least on current implementations) which converts a 32-bit pointer to its 64-bit equivalent, - Change the MI code to utilise the above two items in all the right places, - Implement netbsd32___sigaction_sigtramp(). Tested on Sparc64 by Matt Green.
1.65	21-Sep-2002	manu	- Introduce a e_fault field in struct proc to provide emulation specific memory fault handler. IRIX uses irix_vm_fault, and all other emulation use NULL, which means to use uvm_fault. - While we are there, explicitely set to NULL the uninitialized fields in struct emul: e_fault and e_sysctl on most ports - e_fault is used by the trap handler, for now only on mips. In order to avoid intrusive modifications in UVM, the function pointed by e_fault does not has exactly the same protoype as uvm_fault: int uvm_fault __P((struct vm_map , vaddr_t, vm_fault_t, vm_prot_t)); int e_fault __P((struct proc , vaddr_t, vm_fault_t, vm_prot_t)); - In IRIX share groups, all the VM space is shared, except one page. This bounds us to have different VM spaces and synchronize modifications to the VM space accross share group members. We need an IRIX specific hook to the page fault handler in order to propagate VM space modifications caused by page faults.
1.64	07-Jul-2002	fvdl	Move netbsd32_sysarch to netbsd32_machdep.c
1.63	16-Mar-2002	christos	branches: 1.63.4; make the stackgap_{init,alloc} functions MP friendly (i.e. pass struct proc * in, instead of using curproc). While there add an optional size argument to stackgap_init.
1.62	13-Nov-2001	lukem	add RCSIDs (including regeneration of files as appropriate)
1.61	18-Sep-2001	jdolecek	Make the setregs hook emulation-specific, rather than executable format specific. Struct emul has a e_setregs hook back, which points to emulation-specific setregs function. es_setregs of struct execsw now only points to optional executable-specific setup function (this is only used for ECOFF).
1.60	19-Jun-2001	fvdl	branches: 1.60.2; 1.60.4; Some of this was sparc-specific, so ifdef __sparc__ it (XXX). Also, change the alignment of one structure with an MD ifdef. Should be moved into the netbsd32_machdep parts.
1.59	18-Jun-2001	christos	Add an e_trapsignal member to struct emul, so that emulated processes can send the appropriate signal depending on the trap type.
1.58	30-May-2001	mrg	use _KERNEL_OPT.
1.57	08-Feb-2001	mrg	branches: 1.57.2; split up netbsd32_netbsd.c into 9 new files, leaving only those syscalls that have no special interpretations besides simple syscall args conversion.
1.56	07-Feb-2001	mrg	move the static inline conversion functions into a header file so other files can see these. note a bunch of functions that should be moved into their own files.
1.55	06-Feb-2001	eeh	Specify a process' address space limits for uvmspace_exec().
1.54	04-Feb-2001	mrg	change_utimes32() was copyin()ing a struct timeval, not netbsd32_timeval. general clean up.
1.53	04-Feb-2001	mrg	emulate kern.boottime. now 32-bit w(1) works properly.
1.52	04-Feb-2001	mrg	make sysctl vm.loadavg work.
1.51	03-Feb-2001	mrg	sync a comment from sys_execve(). make netbsd32_recvfrom() work.
1.50	02-Feb-2001	mrg	implement netbsd32_lchflags & netbsd32_utrace
1.49	02-Feb-2001	mrg	de-static netbsd32_exec_aout_prep_[zno]magic(). de-static netbsd32_from_stat43(). move the guts of netbsd32_execve() into netbsd32_execve2(). all of are for the forthcoming sunos32 compat mode (for sparc64).
1.48	22-Jan-2001	jdolecek	Use CHECK_ALT_SYMLINK() instead CHECK_ALT_EXISTS() where appropriate. This addresses kern/11757.
1.47	22-Dec-2000	jdolecek	split off thread specific stuff from struct sigacts to struct sigctx, leaving only signal handler array sharable between threads move other random signal stuff from struct proc to struct sigctx This addresses kern/10981 by Matthew Orgass.
1.46	12-Dec-2000	mycroft	Do the __HAVE_SYSCALL_INTERN and __HAVE_MINIMAL_EMUL dance.
1.45	09-Dec-2000	jdolecek	always fill in e_syscall in respective emul_; if the emulation doesn't have it's own separated _syscall() function, use syscall()
1.44	08-Dec-2000	jdolecek	add infrastructure to load emulations and their executable support dynamically via LKM
1.43	03-Dec-2000	fvdl	Use a copied fktrace syscall arg structure with out 'const int' for the filedescriptor to copy arguments, avoiding a warning. XXX
1.42	01-Dec-2000	jdolecek	always define COMPAT_OLDSOCK (this tracks rev.1.55 of kern/uipc_syscalls.c) move definition of emul_netbsd32 from netbsd32_exec.c here fix couple of compile nits I encountered while compiling this with sparc cross-compiler
1.41	01-Dec-2000	jdolecek	add e_path (emulation path) to struct emul, which replaces emulation-specific _emul_path variables change macros CHECK_ALT_{CREAT\|EXIST} to use that, 'root' doesn't need to be passed explicitly any more and _CHECK_ALT_{CREAT\|EXIST} are removed change explicit emul_find() calls in probe functions to get the emulation path from the checked exec switch entry's emulation remove no longer needed header files add e_flags and e_syscall to struct emul; these are unsed and empty for now
1.40	30-Nov-2000	jdolecek	sync netbsd32_execve() with sys_execve() - this involves VMCMD_RELATIVE support, couple of debugging printfs and addition of doexechooks() call also fix one FREE() which should be free()
1.39	28-Nov-2000	mrg	make this compile again, after execsw/lkm changes.
1.38	28-Sep-2000	eeh	Add support for variable end of user stacks needed to support COMPAT_NETBSD32: `struct vmspace' has a new field `vm_minsaddr' which is the user TOS. PS_STRINGS is deprecated in favor of curproc->p_pstr which is derived from `vm_minsaddr'. Bump the kernel version number.
1.37	24-Sep-2000	martin	The ovadvise syscall is (correctly) listed as STD, so move it's implementation to another place. This makes kernels without options COMPAT_43 link.
1.36	19-Aug-2000	eeh	Fix netbsd32_ioctls.
1.35	03-Aug-2000	thorpej	Convert namei pathname buffer allocation to use the pool allocator.
1.34	14-Jul-2000	thorpej	- Fix the likely cause of the "ps(1) hangs machine" problem. Always vslock the user pages for the data being copied out to userspace, so that we won't sleep while holding a lock in case we need to fault the pages in. - Sprinkle some const and ANSI'ify some things while here.
1.33	13-Jul-2000	thorpej	Sync w/ kern_time.c and sys_generic.c
1.32	09-Jul-2000	mrg	- massive warning fix fest. - fix pread/pwrite return values (plus some other syscalls that looked similarly broken). - prototypes and clean up for netbsd32_ioctl.c now getpw*() works under compat32!
1.31	09-Jul-2000	mrg	look in /emul/netbsd32 for __stat13() and __lstat13().
1.30	28-Jun-2000	mrg	remove include of <vm/vm.h>. <vm/vm.h> -> <uvm/uvm_extern.h>
1.29	26-Jun-2000	mrg	remove/move more mach vm header files: <vm/pglist.h> -> <uvm/uvm_pglist.h> <vm/vm_inherit.h> -> <uvm/uvm_inherit.h> <vm/vm_kern.h> -> into <uvm/uvm_extern.h> <vm/vm_object.h> -> nothing <vm/vm_pager.h> -> into <uvm/uvm_pager.h> also includes a bunch of <vm/vm_page.h> include removals (due to redudancy with <vm/vm.h>), and a scattering of other similar headers.
1.28	30-May-2000	eeh	branches: 1.28.2; Include "opt_DDB.h" to enable the DDB sysctls.
1.27	27-May-2000	thorpej	branches: 1.27.2; sleep() -> tsleep()
1.26	27-May-2000	sommerfeld	Reduce use of curproc in several places: - Change ktrace interface to pass in the current process, rather than p->p_tracep, since the various ktr* function need curproc anyway. - Add curproc as a parameter to mi_switch() since all callers had it handy anyway. - Add a second proc argument for inferior() since callers all had curproc handy. Also, miscellaneous cleanups in ktrace: - ktrace now always uses file-based, rather than vnode-based I/O (simplifies, increases type safety); eliminate KTRFLAG_FD & KTRFAC_FD. Do non-blocking I/O, and yield a finite number of times when receiving EWOULDBLOCK before giving up. - move code duplicated between sys_fktrace and sys_ktrace into ktrace_common. - simplify interface to ktrwrite()
1.25	30-Mar-2000	augustss	Kill register declarations.
1.24	23-Mar-2000	thorpej	New callout mechanism with two major improvements over the old timeout()/untimeout() API: - Clients supply callout handle storage, thus eliminating problems of resource allocation. - Insertion and removal of callouts is constant time, important as this facility is used quite a lot in the kernel. The old timeout()/untimeout() API has been removed from the kernel.
1.23	06-Feb-2000	eeh	Add support for -current's ELF32 exec format.
1.22	31-Jan-2000	christos	Regen
1.21	31-Dec-1999	eeh	netbsd32_close() would work better if it called sys_close() rather than sys_write(). netbsd32_getfsstat() cannot just copyin()/copyout(), convert the structures, and call sys_getffstat(). sys_getffstat() wants to do its own copyin()/copyout(). So we need to implent the whole of sys_getffstat() in netbsd32_getfsstat().
1.20	30-Dec-1999	eeh	Update to 32-bit compatibility routines.
1.19	11-Oct-1999	eeh	branches: 1.19.2; Add netbsd32_compat_14.c Rename everything from compat_netbsd32 -> netbsd32 so we don't have silly names like compat_14_compat_netbsd32_sys_shmctl().
1.18	28-Sep-1999	bouyer	branches: 1.18.2; Remplace kern.shortcorename sysctl with a more flexible sheme, core filename format, which allow to change the name of the core dump, and to relocate it in a directory. Credits to Bill Sommerfeld for giving me the idea :) The default core filename format can be changed by options DEFCORENAME and/or kern.defcorename Create a new sysctl tree, proc, which holds per-process values (for now the corename format, and resources limits). Process is designed by its pid at the second level name. These values are inherited on fork, and the corename fomat is reset to defcorename on suid/sgid exec. Create a p_sugid() function, to take appropriate actions on suid/sgid exec (for now set the P_SUGID flag and reset the per-proc corename). Adjust dosetrlimit() to allow changing limits of one proc by another, with credential controls.
1.17	05-Aug-1999	thorpej	Change the semantics of splsoftclock() to be like other spl() functions, that is priority is rasied. Add a new spllowersoftclock() to provide the atomic drop-to-softclock semantics that the old splsoftclock() provided, and update calls accordingly. This fixes a problem with using the "rnd" pseudo-device from within interrupt context to extract random data (e.g. from within the softnet interrupt) where doing so would incorrectly unblock interrupts (causing all sorts of lossage). XXX 4 platforms do not have priority-raising capability: newsmips, sparc, XXX sparc64, and VAX. This platforms still have this bug until their XXX spl() functions are fixed.
1.16	20-Jul-1999	thorpej	Move the call of cpu_wait() out of the wait4() functions, and into the body of reaper(), right before the call to uvm_exit(). cpu_wait() must be done before uvm_exit() because the resources it frees might be located in the PCB.
1.15	17-Jun-1999	thorpej	Make uvm_vslock() return the error code from uvm_fault_wire(). All places which use uvm_vslock() should now test the return value. If it's not KERN_SUCCESS, wiring the pages failed, so the operation which is using uvm_vslock() should error out. XXX We currently just EFAULT a failed uvm_vslock(). We may want to do more about translating error codes in the future.
1.14	09-Jun-1999	christos	Propagate kern changes
1.13	26-May-1999	thorpej	XXX Pass VM_PROT_NONE to uvm_vslock() as access_type. Why are we even vslocking here?! copyout() on its own seems to suffice just about everwhere else, and it's not like the process is going to exit; it's in a system call!
1.12	05-May-1999	thorpej	Add "use counting" to file entries. When closing a file, and it's reference count is 0, wait for use count to drain before finishing the close. This is necessary in order for multiple processes to safely share file descriptor tables.
1.11	25-Mar-1999	mrg	branches: 1.11.4; SPARC32->NETBSD32
1.10	25-Mar-1999	mrg	move sparc32 to netbsd32; split out MD part (signal handling) (mostly via repository copy, rename and perl -pi :-)
1.9	25-Mar-1999	mrg	formatting nits
1.8	24-Mar-1999	mrg	completely remove Mach VM support. all that is left is the all the header files as UVM still uses (most of) these.
1.7	18-Dec-1998	drochner	solve the COMPAT_OLDSOCK/MSG_COMPAT problem differently: The source files which need MSG_COMPAT define COMPAT_OLDSOCK.
1.6	01-Oct-1998	eeh	Overhaul. Now will run simple things like /bin/sh and /bin/echo.
1.5	11-Sep-1998	eeh	Add some copyin()/copyout()s. These need to be done but there are more annoying issues, so I'll just check in this snapshot.
1.4	30-Aug-1998	eeh	Some more 64-bit cleanup. Now everything compiles.
1.3	29-Aug-1998	eeh	Some more 64-bit-ification.
1.2	26-Aug-1998	mrg	use right syscalls. add converters for timespec and semid_ds
1.1	26-Aug-1998	mrg	add a 32-bit compatibility module for the sparc64 port, so it can run NetBSD/sparc binaries with a LP64 kernel.

Add a new function pointer to struct emul, pointing at a function that will return the default VM map address. The default function is uvm_map_defaultaddr, which just uses the VM_DEFAULT_ADDRESS macro. This gives emulations control over the default map address, and allows things to be mapped at the right address (in 32bit range) for COMPAT_NETBSD32. * Add code to adjust the data and stack limits when a COMPAT_NETBSD32 or COMPAT_SVR4_32 binary is executed. * Don't use USRSTACK in kern_resource.c, use p_vmspace->vm_minsaddr instead (emulations might have set it differently) * Since this changes struct emul, bump kernel version to 3.99.2 Tested on amd64, compile-tested on sparc64.

1.143.6.4	21-Jul-2008	wrstuden	Add support for compiling SA as an option. Implied by COMPAT_40. i386 kernels both with COMPAT_40 and with no compat options (and thus no SA) compile. No functional changes intended.
1.143.6.3	27-Jun-2008	wrstuden	Add getucontext32_sa() and getucontext_sa(), and use them. They are sa-specific versions of getucontext{,32}(). The main difference is that they do NOT require the p_lock be held. We report an empty signal mask, both to avoid needing p_lock and because the process signal mask is almost always 0 for SA.
1.143.6.2	23-Jun-2008	wrstuden	Sync w/ -current. 34 merge conflicts to follow.
1.143.6.1	10-May-2008	wrstuden	Initial checkin of re-adding SA. Everything except kern_sa.c compiles in GENERIC for i386. This is still a work-in-progress, but this checkin covers most of the mechanical work (changing signalling to be able to accomidate SA's process-wide signalling and re-adding includes of sys/sa.h and savar.h). Subsequent changes will be much more interesting. Also, kern_sa.c has received partial cleanup. There's still more to do, though.

1.168.4.2	09-Feb-2011	bouyer	Proper definitions for quotactl
1.168.4.1	20-Jan-2011	bouyer	Snapshot of work in progress on a modernised disk quota system: - new quotactl syscall (versionned for backward compat), which takes as parameter a path to a mount point, and a prop_dictionary (in plistref format) describing commands and arguments. For each command, status and data are returned as a prop_dictionary. quota commands features will be added to take advantage of this, exporting quota data or getting quota commands as plists. - new on disk-format storage (all 64bit wide), integrated to metadata for ffs (and playing nicely with wapbl). Quotas are enabled on a ffs filesystem via superblock flags. tunefs(8) can enable or disable quotas. On a quota-enabled filesystem, fsck_ffs(8) will track per-uid/gid block and inode usages, and will check and update quotas in Pass 6. quota usage and limits are stored in unliked files (one for users, one for groups)l fsck_ffs(8) will create the files if needed, or free them if needed. This means that after enabling or disabling quotas on a filesystem; a fsck_ffs(8) run is required. quotacheck(8) is not needed any more, on a unclean shutdown fsck or journal replay will take care of fixing quotas. newfs(8) can create a ready-to-mount quota-enabled filesystem (superblock flags are set and quota inodes are created). Other new features or semantic changes: - default quota datas, applied to users or groups which don't already have a quota entry - per-user/group grace time (instead of a filesystem global one) - 0 really means "nothing allowed at all", not "no limit". If you want "no limit", set the limit to UQUAD_MAX (tools will understand "unlimited" and "-") A quota file is structured as follow: it starts with a header, containing a few per-filesystem values, and the default quota limits. Quota entries are linked together as a simple list, each entry has a pointer (as an offset withing the file) to the next. The header has a pointer to a list of free quota entries, and a hash table of in-use entries. The size of the hash table depends on the filesystem block size (header+hash table should fit in the first block). The file is not sparse and is a multiple of filesystem block size (when the free quota entry list is empty a new filesystem block is allocated). quota entries to not cross filesystem block boundaries. In memory, the kernel keeps a cache of recently used quota entries as a reference to the block number, and offset withing the block. The quota entry itself is keept in the buf cache. fsck_ffs(8), tunefs(8) and newfs(8) supports are completed (with related atf tests :) The kernel can update disk usage and report it via quotactl(2). Todo: enforce quotas limits (limits are not checked by kernel yet) update repquota, edquota and rpc.rquotad to the new world implement compat_50_quotactl ioctl. update quotactl(2) man page fsck_ffs required fixes so that allocating new blocks or inodes will properly update the superblock and cg sumaries. This was not an issue up to now because superblock and cg sumaries check happened last, but now allocations or frees can happen in pass 6.

1.8	24-Dec-2019	kamil	Introduce PT_LWPSTATUS + PT_LWPNEXT, obsolete PT_LWPINFO PT_LWPINFO is a legacy ptrace(2) operation that was originally intended to retrieve the thread (LWP) information inside a traced process. It has a number of flaws and is confused with PT_LWPINFO from FreeBSD. PT_LWPSTATUS and PT_LWPNEXT address the problems (shortly by: rename, removal of pl_event) and introduces new features: signal context (pl_sigpend, pl_sigmask), LWP name (pl_name), LWP TLS base address (pl_private). The private pointer was so far missing information for a debugger. PT_LWPSTATUS@nnn is now shipped with core(5) files and contain LWP specific information, so far missed in the core(5) files. PT_LWPSTATUS retrieves LWP information for the prompted thread. PT_LWPNEXT retrieves LWP information for the next thread, borrowing the semantics from NetBSD specific PT_LWPINFO. PT_LWPINFO is namespaced with __LEGACY_PT_LWPINFO and still available for the foreseeable future, without plans of removing it. Add ATF tests for PT_LWPSTATUS + PT_LWPNEXT. Keep ATF tests for PT_LWPINFO. Switch GDB to new API. Proposed on tech-kern@.
1.7	04-Jun-2019	mgorny	branches: 1.7.2; compat32: Translate userland PT_* request values into kernel codes Currently, the compat32 passes PT_* request values to kernel functions without translation. This works fine for low PT_* requests that happen to have the same values both on i386 and amd64. However, for requests higher than PT_SETFPREGS, the value passed from userland (matching i386 const) does not match the correct kernel (amd64) request. As a result, e.g. when compat32 process calls PT_GETDBREGS, kernel actually processes it as PT_SETSTEP. To resolve this, introduce support for compat32 PT_* request translation. The interface is based on PTRACE_TRANSLATE_REQUEST32 macro that is defined to a mapping function on architectures needing it. In case of amd64, this function maps userland i386 PT_* values into appropriate amd64 PT_* values. For the time being, the two additional PT_GETXMMREGS and PT_SETXMMREGS requests are unsupported due to lack of matching free amd64 constant.

1.5	17-Dec-2017	christos	branches: 1.5.2; 1.5.4; handle siginfo requests for ptrace32
1.4	23-Feb-2017	kamil	branches: 1.4.6; 1.4.12; Introduce PT_GETDBREGS and PT_SETDBREGS in ptrace(2) on i386 and amd64 This interface is modeled after FreeBSD API with the usage. This replaced previous watchpoint API. The previous one was introduced recently in NetBSD-current and remove its spurs without any backward-compatibility. Design choices for Debug Register accessors: - exec() (TRAP_EXEC event) must remove debug registers from LWP - debug registers are only per-LWP, not per-process globally - debug registers must not be inherited after (v)forking a process - debug registers must not be inherited after forking a thread - a debugger is responsible to set global watchpoints/breakpoints with the debug registers, to achieve this PTRACE_LWP_CREATE/PTRACE_LWP_EXIT event monitoring function is designed to be used - debug register traps must generate SIGTRAP with si_code TRAP_DBREG - debugger is responsible to retrieve debug register state to distinguish the exact debug register trap (DR6 is Status Register on x86) - kernel must not remove debug register traps after triggering a trap event a debugger is responsible to detach this trap with appropriate PT_SETDBREGS call (DR7 is Control Register on x86) - debug registers must not be exposed in mcontext - userland must not be allowed to set a trap on the kernel Implementation notes on i386 and amd64: - the initial state of debug register is retrieved on boot and this value is stored in a local copy (initdbregs), this value is used to initialize dbreg context after PT_GETDBREGS - struct dbregs is stored in pcb as a pointer and by default not initialized - reserved registers (DR4-DR5, DR9-DR15) are ignored Further ideas: - restrict this interface with securelevel Tested on real hardware i386 (Intel Pentium IV) and amd64 (Intel i7). This commit enables 390 debug register ATF tests in kernel/arch/x86. All tests are passing. This commit does not cover netbsd32 compat code. Currently other interface PT_GET_SIGINFO/PT_SET_SIGINFO is required in netbsd32 compat code in order to validate reliably PT_GETDBREGS/PT_SETDBREGS. This implementation does not cover FreeBSD specific defines in their <x86/reg.h>: DBREG_DR7_LOCAL_ENABLE, DBREG_DR7_GLOBAL_ENABLE, DBREG_DR7_LEN_1 etc. These values tend to be reinvented by each tracer on its own. GNU Debugger (GDB) works with NetBSD debug registers after adding this patch: --- gdb/amd64bsd-nat.c.orig 2016-02-10 03:19:39.000000000 +0000 +++ gdb/amd64bsd-nat.c @@ -167,6 +167,10 @@ amd64bsd_target (void) #ifdef HAVE_PT_GETDBREGS +#ifndef DBREG_DRX +#define DBREG_DRX(d,x) ((d)->dr[(x)]) +#endif + static unsigned long amd64bsd_dr_get (ptid_t ptid, int regnum) { Another reason to stop introducing unpopular defines covering machine specific register macros is that these value varies across generations of the same CPU family.

1.3	15-Dec-2016	kamil	branches: 1.3.2; Add support for hardware assisted watchpoints/breakpoints API in ptrace(2) Add new ptrace(2) calls: - PT_COUNT_WATCHPOINTS - count the number of available hardware watchpoints - PT_READ_WATCHPOINT - read struct ptrace_watchpoint from the kernel state - PT_WRITE_WATCHPOINT - write new struct ptrace_watchpoint state, this includes enabling and disabling watchpoints The ptrace_watchpoint structure contains MI and MD parts: typedef struct ptrace_watchpoint { int pw_index; /* HW Watchpoint ID (count from 0) / lwpid_t pw_lwpid; / LWP described / struct mdpw pw_md; / MD fields / } ptrace_watchpoint_t; For example amd64 defines MD as follows: struct mdpw { void md_address; int md_condition; int md_length; }; These calls are protected with the __HAVE_PTRACE_WATCHPOINTS guard. Tested on amd64, initial support added for i386 and XEN. Sponsored by <The NetBSD Foundation>
1.2	02-Nov-2016	pgoyette	branches: 1.2.2; 1.2.4; * Split sys/kern/sys_process.c into three parts: 1 - ptrace(2) syscall for native emulation 2 - common ptrace(2) syscall code (shared with compat_netbsd32) 3 - support routines that are shared with PROCFS and/or KTRACE * Add module glue for #1 and #2. Both modules will be built-in to the kernel if "options PTRACE" is included in the config file (this is the default, defined in sys/conf/std). * Mark the ptrace(2) syscall as modular in syscalls.master (generated files will be committed shortly). * Conditionalize all remaining portions of PTRACE code on a new kernel option PTRACE_HOOKS. XXX Instead of PROCFS depending on 'options PTRACE', we should probably just add a procfs attribute to the sys/kern/sys_process.c file's entry in files.kern, and add PROCFS to the "#if defineds" for process_domem(). It's really confusing to have two different ways of requiring this file.

Users will still be able to use all the other /proc files. This change won't affect other procfs files neither Linux compat features within mount_procfs(8). /proc/#/ctl isn't available on Linux. Remove: - /proc/#/ctl from mount_procfs(8) - P_FSTRACE note from the documentation of ps(1) - /proc/#/ctl and filesystem tracing documentation from mount_procfs(8) - KAUTH_REQ_PROCESS_PROCFS_CTL documentation from kauth(9) - source code file miscfs/procfs/procfs_ctl.c - PFSctl and procfs_doctl() from sys/miscfs/procfs/procfs.h - KAUTH_REQ_PROCESS_PROCFS_CTL from sys/sys/kauth.h - PSL_FSTRACE (0x00010000) from sys/sys/proc.h - P_FSTRACE (0x00010000) from sys/sys/sysctl.h Reduce code complexity after removal of this functionality. Update TODO.ptrace accordingly: remove two entries about /proc tracing. Do not keep legacy notes as comments in the headers about removed PSL_FSTRACE / P_FSTRACE, as this interface had little number of users (close or equal to zero). Proposed on tech-kern@. All filesystem tracing utility users are encouraged to switch to ptrace(2). Sponsored by <The NetBSD Foundation> untangle the mess: - factor out common code - break each ptrace subcall to its own sub-function .. more to come ... - reduce ifdef ugliness by moving it up top. - factor out PT_IO and make PT_{READ,WRITE}_{I,D} use it - factor out PT_DUMPCORE - factor out sendsig code .. more to come ... handle siginfo requests for ptrace32 ptrace: Partially undo PT_{READ,WRITE}_{I,D} and unbreak these commands The refactored code did not work and was generating EFAULT. Sponsored by <The NetBSD Foundation> Merge the code back; the problem was that since we are reading/writing to a kernel address for PT_{READ,WRITE}_{I,D} we need the kernel vmspace. provide separate read and write functions to accomodate register functions that need a size argument. don't ignore error from copyout_piod Use the proper process (the tracee) to get information about lwps and registers and the tracer for vmspace. Add new sysctl(3) entry: security.models.extensions.user_set_dbregs Model this new sysctl(3) entry after "user_set_cpu_affinity" in the same level of sysctl(3) switches. Allow to read unconditionally Debug Registers (no change here). This is convenient as even if a user of a debugger does not use hardware assisted watchpoints/breakpoints, a debugger can still prompt these values to store in an internal cache with context of registers. Reading them should have no security concerns. Add a paranoid MI switch that prohibits by default setting these registers by a regular user (non-superuser). Make this switch disabled by default. There are enough reserved bits out there to allow using them unconditionally on hardened hosts. Features shipped with Debug Registers are optional features in debuggers. There is no reduction in elementary functionality. Reviewed by <christos> Sponsored by <The NetBSD Foundation>

1.7.2.2	14-May-2008	wrstuden	Per discussion with ad, remove most of the #include <sys/sa.h> lines as they were including sa.h just for the type(s) needed for syscallargs.h. Instead, create a new file, sys/satypes.h, which contains just the types needed for syscallargs.h. Yes, there's only one now, but that may change and it's probably more likely to change if it'd be difficult to handle. :-) Per discussion with matt at n dot o, add an include of satypes.h to sigtypes.h. Upcall handlers are kinda signal handlers, and signalling is the header file that's already included for syscallargs.h that closest matches SA. This shaves about 3000 lines off of the diff of the branch relative to the base. That also represents about 18% of the total before this checkin. I think this reduction is very good thing.
1.7.2.1	10-May-2008	wrstuden	Initial checkin of re-adding SA. Everything except kern_sa.c compiles in GENERIC for i386. This is still a work-in-progress, but this checkin covers most of the mechanical work (changing signalling to be able to accomidate SA's process-wide signalling and re-adding includes of sys/sa.h and savar.h). Subsequent changes will be much more interesting. Also, kern_sa.c has received partial cleanup. There's still more to do, though.

1.53	06-Nov-2021	thorpej	branches: 1.53.4; COMPAT_NETBSD32 is all about running the 32-bit flavor of native binaries on a 64-bit platform[], as such: - Make the logic about which "sendsig" flavor to call MI (as it is in the native 64-bit environment) and follow the same rules as the native 32-bit environment. - Make COMPAT_NETBSD32 x COMPAT_16 work the same as it would in the native 32-bit environment by providing a netbsd32_sendsig_sigcontext_16_hook, rather than overriding the entire sendsig logic with a netbsd32_sendsig_hook. - In netbsd32___sigaction_sigtramp(), make sure the compat_netbsd32_16 module is loaded if the trampoline version specifies a sigcontext style handler, otherwise return EINVAL so that libc can try again with siginfo style. [] ...except for arm32, which uses it to mean "run 32-bit OABI binaries from the 32-bit EABI environment". Doing it this way was arguably a mistake, but we are stuck with it for now, so support it by providing a machine- dependent override for netbsd32_sendsig() that also disables the corresponding logic in netbsd32___sigaction_sigtramp().

1.17	15-Mar-2006	cube	branches: 1.17.10; 1.17.12; SA introduce a new case of siginfo structure. Be ready for it when the time comes to support SA in COMPAT_NETBSD32 (which is soon).

1.6	18-Jan-2003	thorpej	branches: 1.6.2; Merge the nathanw_sa branch.
1.5	27-Nov-2002	atatat	Complete the rename: s/sa_/<compat>_sa_/g Also tweak the darwin siginfo stuff to avoid the same type of collision.
1.4	23-Oct-2002	scw	In preparation for COMPAT_NETBSD32 on SH-5: - The MD netbsd32_machdep.h header now defines the 32-bit pointer type instead of using u_int32_t everywhere, - The MD netbsd32_machdep.h header now defines a macro (at least on current implementations) which converts a 32-bit pointer to its 64-bit equivalent, - Change the MI code to utilise the above two items in all the right places, - Implement netbsd32___sigaction_sigtramp(). Tested on Sparc64 by Matt Green.
1.3	04-Jul-2002	thorpej	Add kernel support for having userland provide the signal trampoline: * struct sigacts gets a new sigact_sigdesc structure, which has the sigaction and the trampoline/version. Version 0 means "legacy kernel provided trampoline". Other versions are coordinated with machine- dependent code in libc. * sigaction1() grows two more arguments -- the trampoline pointer and the trampoline version. * A new __sigaction_sigtramp() system call is provided to register a trampoline along with a signal handler. * The handler is no longer passed to sensig() functions. Instead, sendsig() looks up the handler by peeking in the sigacts for the process getting the signal (since it has to look in there for the trampoline anyway). * Native sendsig() functions now select the appropriate trampoline and its arguments based on the trampoline version in the sigacts. Changes to libc to use the new facility will be checked in later. Kernel version not bumped; we will ride the 1.6C bump made recently.

1.29.4.4	27-Jun-2008	wrstuden	Add getucontext32_sa() and getucontext_sa(), and use them. They are sa-specific versions of getucontext{,32}(). The main difference is that they do NOT require the p_lock be held. We report an empty signal mask, both to avoid needing p_lock and because the process signal mask is almost always 0 for SA.
1.29.4.3	23-Jun-2008	wrstuden	Sync w/ -current. 34 merge conflicts to follow.
1.29.4.2	14-May-2008	wrstuden	Per discussion with ad at n dot o, revert signal mask handling changes. The l_sigstk changes are most likely totally un-needed as SA will never use a signal stack - we send an upcall (or will as other diffs are brought in). The l_sigmask changes were too controvertial. In all honesty, I think it's probably best to revert them. The main reason they were there is the fact that in an SA process, we don't mask signals per kernel thread, we mask them per user thread. In the kernel, we want them all to get turned into upcalls. Thus the normal state of l_sigmask in an SA process is for it to always be empty. While we are in the process of delivering a signal, we want to temporarily mask a signal (so we don't recursively exhaust our upcall stacks). However signal delivery is rare (important, but rare), and delivering back-to-back signals is even rarer. So rather than cause every user of a signal mask to be prepared for this very rare case, we will just add a second check later in the signal delivery code. Said change is not in this diff. This also un-compensates all of our compatability code for dealing with SA. SA is a NetBSD-specific thing, so there's no need for Irix, Linux, Solaris, SVR4 and so on to cope with it. As previously, everything other than kern_sa.c compiles in i386 GENERIC as of this checkin. I will switch to ALL soon for compile testing.
1.29.4.1	10-May-2008	wrstuden	Initial checkin of re-adding SA. Everything except kern_sa.c compiles in GENERIC for i386. This is still a work-in-progress, but this checkin covers most of the mechanical work (changing signalling to be able to accomidate SA's process-wide signalling and re-adding includes of sys/sa.h and savar.h). Subsequent changes will be much more interesting. Also, kern_sa.c has received partial cleanup. There's still more to do, though.

Remove the filesystem tracing feature This is a legacy interface from 4.4BSD, and it was introduced to overcome shortcomings of ptrace(2) at that time, which are no longer relevant (performance). Today /proc/#/ctl offers a narrow subset of ptrace(2) commands and is not applicable for modern applications use beyond simplistic tracing scenarios. This removal will simplify kernel internals. Users will still be able to use all the other /proc files. This change won't affect other procfs files neither Linux compat features within mount_procfs(8). /proc/#/ctl isn't available on Linux. Remove: - /proc/#/ctl from mount_procfs(8) - P_FSTRACE note from the documentation of ps(1) - /proc/#/ctl and filesystem tracing documentation from mount_procfs(8) - KAUTH_REQ_PROCESS_PROCFS_CTL documentation from kauth(9) - source code file miscfs/procfs/procfs_ctl.c - PFSctl and procfs_doctl() from sys/miscfs/procfs/procfs.h - KAUTH_REQ_PROCESS_PROCFS_CTL from sys/sys/kauth.h - PSL_FSTRACE (0x00010000) from sys/sys/proc.h - P_FSTRACE (0x00010000) from sys/sys/sysctl.h Reduce code complexity after removal of this functionality. Update TODO.ptrace accordingly: remove two entries about /proc tracing. Do not keep legacy notes as comments in the headers about removed PSL_FSTRACE / P_FSTRACE, as this interface had little number of users (close or equal to zero). Proposed on tech-kern@. All filesystem tracing utility users are encouraged to switch to ptrace(2). Sponsored by <The NetBSD Foundation> untangle the mess: - factor out common code - break each ptrace subcall to its own sub-function .. more to come ... - reduce ifdef ugliness by moving it up top. - factor out PT_IO and make PT_{READ,WRITE}_{I,D} use it - factor out PT_DUMPCORE - factor out sendsig code .. more to come ... handle siginfo requests for ptrace32 ptrace: Partially undo PT_{READ,WRITE}_{I,D} and unbreak these commands The refactored code did not work and was generating EFAULT. Sponsored by <The NetBSD Foundation> Merge the code back; the problem was that since we are reading/writing to a kernel address for PT_{READ,WRITE}_{I,D} we need the kernel vmspace. provide separate read and write functions to accomodate register functions that need a size argument. don't ignore error from copyout_piod Use the proper process (the tracee) to get information about lwps and registers and the tracer for vmspace. Add new sysctl(3) entry: security.models.extensions.user_set_dbregs Model this new sysctl(3) entry after "user_set_cpu_affinity" in the same level of sysctl(3) switches. Allow to read unconditionally Debug Registers (no change here). This is convenient as even if a user of a debugger does not use hardware assisted watchpoints/breakpoints, a debugger can still prompt these values to store in an internal cache with context of registers. Reading them should have no security concerns. Add a paranoid MI switch that prohibits by default setting these registers by a regular user (non-superuser). Make this switch disabled by default. There are enough reserved bits out there to allow using them unconditionally on hardened hosts. Features shipped with Debug Registers are optional features in debuggers.

1.54.2.1	02-Aug-2025	perseant	Sync with HEAD
1.56	19-Jan-2021	simonb	The read/write/send/recv system calls return ssize_t because -1 is returned on error. Therefore we must restrict the lengths of any buffers to NETBSD32_SSIZE_MAX with compat32 to avoid garbage return values. Fixes ATF lib/libc/sys/t_write:write_err.

1.48	12-Nov-2018	maxv	Fix inverted logic, which leads to buffer overflow. Detected by kASan.

1.46	10-May-2018	christos	add {send,recv}mmsg
1.45	03-May-2018	christos	Fix COMPAT_NETBSD32 cmsg handling: 1. alignment was wrong for > 1 message 2. macros were doing incorrect pointer comparisons, fortunately ending the iteration early after the fists cmsg instead of crashing. 3. don't output 32 bit ktrace records for cmsg. 32 bit programs running under emulation on 64 bit systems should produce 64 bit ktrace records so that the native ktrace can handle the records; remove extra arguments that are now not needed (the 32 bit msghdr). 4. output the correct type for cmsg trace records. 5. output all the cmsg records in traces instead of just the first one. Welcome to 8.99.15 because of the argument removal. XXX: Really all the code should be changed to use the CMSG_{FIRST,NXT}HDR macros...
1.44	13-Sep-2016	martin	branches: 1.44.8; 1.44.14; Make the ktrace record written by do_sys_sendmsg/do_sys_recvmsg overridable by the caller. Use this in compat_netbsd32 to log the 32bit version, so the 32bit userland kdump is happy.
1.43	08-Sep-2016	martin	recvmsg: ktrace the 32bit message header, not the native (64bit) version.
1.42	22-Jul-2015	maxv	Memory leak, triggerable from an unprivileged user.
1.41	18-Aug-2012	martin	branches: 1.41.2; 1.41.14; 1.41.16; Do not use a userland pointer, but the copied-in kernel version instead. While there, reorder loop end condition for efficency. Fixes net/fdpass tests on all archs with separate kernel/userland VA.
1.40	30-Jul-2012	matt	Make SCM_RIGHTS work correctly. (make sure to advance m if we've completely dealt with, the next mbuf (if any) comes into play).
1.39	20-Jan-2012	joerg	branches: 1.39.2; Change CMSG_SPACE and CMSG_LEN to provide Integer Constant Expressions again. This was changed in sys/socket.h r1.51 to work around fallout from the IPv6 aux data migration. It broke the historic ABI on some platforms. This commit restores compatibility for netbsd32 code on such platforms and provides a template for future changes to the CMSG_* alignment. Revert PCC/Clang workarounds in postfix and tmux.
1.38	13-Jan-2012	joerg	Reduce difference between recvfrom/recvmsg for netbsd32 and the native version. This fixes the bug of lost file descriptors when the control space is not large enough.
1.37	23-Apr-2010	rmind	branches: 1.37.8; 1.37.12; Replace M_IOV and some malloc(9)s with kmem(9), and while there: - Fix invalid free (M_TEMP vs M_IOV) in do_sys_recvmsg(), spotted by jakllsch@. Also, same fix in osf1_sys_sendmsg_xopen(). - Fix attempt to free non-allocated memory in error path in netbsd32___getfh30(). - Plug a memory leak in compat_43_netbsd32_orecvmsg().
1.36	22-Jul-2009	njoly	branches: 1.36.2; 1.36.4; Make compat netbsd32 sendmsg follow the native version by allowing empty messages. This let unfdpass regression test work as expected.
1.35	15-Jun-2009	njoly	Make netbsd32 sendmsg(2), do not use an uninitialised value for fetching iovec structures. While here, sync recvmsg(2) to avoid some unneeded casts.
1.34	17-Dec-2008	cegger	branches: 1.34.2; 1.34.4; kill MALLOC and FREE macros.
1.33	24-Jun-2008	ad	branches: 1.33.4; 1.33.12; Replace references to getsock/getvnode.
1.32	29-May-2008	mrg	branches: 1.32.2; remove clause #3 from my license where there are no other copyright holders involved.
1.31	21-Mar-2008	ad	branches: 1.31.2; 1.31.4; 1.31.6; Catch up with descriptor handling changes. See kern_descrip.c revision 1.173 for details.
1.30	20-Dec-2007	dsl	branches: 1.30.6; Convert all the system call entry points from: int foo(struct lwp l, void v, register_t retval) to: int foo(struct lwp l, const struct foo_args uap, register_t retval) Fixup compat code to not write into 'uap' and (in some cases) to actually pass a correctly formatted 'uap' structure with the right name to the next routine. A few 'compat' routines that just call standard ones have been deleted. All the 'compat' code compiles (along with the kernels required to test build it). 98% done by automated scripts.
1.29	08-Dec-2007	dsl	branches: 1.29.4; ANSIfy most of the function definitions in sys/compat (but not ndis). All by the magic of sed ...
1.28	04-Dec-2007	dsl	Remove all the __P
1.27	15-Aug-2007	ad	branches: 1.27.2; 1.27.8; 1.27.10; Changes to make ktrace LKM friendly and reduce ifdef KTRACE. Proposed on tech-kern.
1.26	01-Jun-2007	dsl	branches: 1.26.2; 1.26.6; Split sys_bind() and sys_connect() so that compat code can use common code once the 'address' has been copied into an mbuf. Add extra flags for 'struct msghdr.msg_flags' to indicate that the address and control are already in mbufs, and that the uio structure is in userspace for sending data, rename sendit() to do_sys_sendmsg() to ensure no old code passes in random flags. Changes to compat code to use new functions - removing some stackgap use. Fix a 'use after free' in compat_43_sys_recvmsg. I *THINK* the code that converts 'cmsg' formatted data is borked! svr4_stream.c ought to be generated from svr4_32_stream.c during the build.
1.25	31-May-2007	christos	message size == 0 is valid. From Markus Mayer
1.24	18-Mar-2007	dsl	Change all the NETBSD32PTR64(SCARG(uap, xxx))) to SCARG_P32(uap, xxx).
1.23	16-Mar-2007	dsl	remove all the double (and triple) casts used to convert 32bit userspace pointers to and from 64bit kernel pointers. Instead use the defines NETBSD32PTR64(p32) to read a 32bit pointer and (the new) NETBSD32PTR32(p32,p64) to write a 32bit pointer throughout. The 32bit pointer is now a struct to enforce the above. amd64 (with linux emul) and sparc64 will both compile (when the arch stuff goes in soon), and amd64 still runs some i386 binaries.
1.22	04-Mar-2007	christos	branches: 1.22.2; 1.22.4; 1.22.6; fix fallout from caddr_t changes.
1.21	04-Mar-2007	christos	Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.
1.20	09-Feb-2007	ad	branches: 1.20.2; Merge newlock2 to head.
1.19	19-Mar-2006	matt	branches: 1.19.8; More variable sized MALLOC -> malloc changes.
1.18	18-Mar-2006	matt	MALLOC -> malloc
1.17	01-Mar-2006	yamt	branches: 1.17.2; 1.17.4; 1.17.6; merge yamt-uio_vmspace branch. - use vmspace rather than proc or lwp where appropriate. the latter is more natural to specify an address space. (and less likely to be abused for random purposes.) - fix a swdmover race.
1.16	11-Dec-2005	christos	branches: 1.16.2; 1.16.4; 1.16.6; merge ktrace-lwp.
1.15	19-Aug-2005	christos	Fix lossage I created with the 64 bit ino_t change.
1.14	31-May-2005	christos	branches: 1.14.2; - add const - avoid shadowed variables.
1.13	26-Feb-2005	perry	nuke trailing whitespace
1.12	21-Oct-2003	fvdl	branches: 1.12.8; 1.12.10; Fix some int vs. NULL comparisons.
1.11	29-Jun-2003	fvdl	branches: 1.11.2; Back out the lwp/ktrace changes. They contained a lot of colateral damage, and need to be examined and discussed more.
1.10	29-Jun-2003	martin	struct proc * -> struct lwp *
1.9	28-Jun-2003	darrenr	Pass lwp pointers throughtout the kernel, as required, so that the lwpid can be inserted into ktrace records. The general change has been to replace "struct proc " with "struct lwp " in various function prototypes, pass the lwp through and use l_proc to get the process pointer when needed. Bump the kernel rev up to 1.6V
1.8	18-Jan-2003	thorpej	Merge the nathanw_sa branch.
1.7	23-Oct-2002	scw	In preparation for COMPAT_NETBSD32 on SH-5: - The MD netbsd32_machdep.h header now defines the 32-bit pointer type instead of using u_int32_t everywhere, - The MD netbsd32_machdep.h header now defines a macro (at least on current implementations) which converts a 32-bit pointer to its 64-bit equivalent, - Change the MI code to utilise the above two items in all the right places, - Implement netbsd32___sigaction_sigtramp(). Tested on Sparc64 by Matt Green.
1.6	13-Nov-2001	lukem	add RCSIDs (including regeneration of files as appropriate)
1.5	17-Jul-2001	jdolecek	Expel MSG_COMPAT/COMPAT_OLDSOCK, make the COMPAT_43 wrappers arrange things as needed. Unfortunately, the check in sockargs() have to stay, since 4.3BSD bind(2), connect(2) and sendto(2) were not versioned at the time :( This code was tested to pass regression tests.
1.4	25-Jun-2001	jdolecek	branches: 1.4.2; Back off the sendit()/recvit() change, some have problems with it
1.3	25-Jun-2001	jdolecek	Add 'kernsa' parameter for sendit()/recvit(); if nonzero, msg->msg_name is supposed to point directly to struct mbuf or struct sockaddr in kernel space as appropriate, rather than being a pointer to memory in userland. This is to be used by compat/* when emulation needs to wrap send{to\|msg}(2)/recv{from\|msg}(2) and modify the passed struct sockaddr.
1.2	30-May-2001	mrg	use _KERNEL_OPT.
1.1	08-Feb-2001	mrg	branches: 1.1.2; 1.1.4; split up netbsd32_netbsd.c into 9 new files, leaving only those syscalls that have no special interpretations besides simple syscall args conversion.

1.11.2.1	02-Jul-2003	darrenr	Apply the aborted ktrace-lwp changes to a specific branch. This is just for others to review, I'm concerned that patch fuziness may have resulted in some errant code being generated but I'll look at that later by comparing the diff from the base to the branch with the file I attempt to apply to it. This will, at the very least, put the changes in a better context for others to review them and attempt to tinker with removing passing of 'struct lwp' through the kernel.

1.31.6.2	14-May-2008	wrstuden	Per discussion with ad, remove most of the #include <sys/sa.h> lines as they were including sa.h just for the type(s) needed for syscallargs.h. Instead, create a new file, sys/satypes.h, which contains just the types needed for syscallargs.h. Yes, there's only one now, but that may change and it's probably more likely to change if it'd be difficult to handle. :-) Per discussion with matt at n dot o, add an include of satypes.h to sigtypes.h. Upcall handlers are kinda signal handlers, and signalling is the header file that's already included for syscallargs.h that closest matches SA. This shaves about 3000 lines off of the diff of the branch relative to the base. That also represents about 18% of the total before this checkin. I think this reduction is very good thing.
1.31.6.1	10-May-2008	wrstuden	Initial checkin of re-adding SA. Everything except kern_sa.c compiles in GENERIC for i386. This is still a work-in-progress, but this checkin covers most of the mechanical work (changing signalling to be able to accomidate SA's process-wide signalling and re-adding includes of sys/sa.h and savar.h). Subsequent changes will be much more interesting. Also, kern_sa.c has received partial cleanup. There's still more to do, though.

In the BSD4.3 compat mode there was a fallback to call sys_getpid_with_ppid() and related functions. In 2008 the compat ifdef was removed in sys/kern/syscalls.master r. 1.216. For purity reasons we probably shall restore the NetBSD original behavior and implement BSD4.3 one as a compat module, however it is not worth the complexity. Align the netbsd32 compat ABI to native ABI and call functions that return two integers as in BSD4.3.

In doing so, it removes several XXXSMPs in the MI code, which is good. * Removes the PMC code of ARM XSCALE. * Removes all the pmc.h files. They were all empty, except for ARM XSCALE. * Reorders the x86 PMC code not to rely on the legacy pmc.h file. The definitions are put in sysarch.h. * Removes the kern/sys_pmc.c file, and along with it, the sys_pmc_control and sys_pmc_get_info syscalls. They are marked as OBSOL in kern, netbsd32 and rump. * Removes the pmc_evid_t and pmc_ctr_t types. * Removes all the associated man pages. The sets are marked as obsolete.

1.134	06-Jan-2018	kamil	branches: 1.134.2; Revert vadvise(2) removal This system call was used in legacy Lisp code, that was inherited to modern age and still compiled against supported compat layers (e.g. in clisp, oaklisp, Franz Lisp). It used to instruct the kernel about paging policy (G/C aware, flush etc). Newly compiled code (assuming that it will detect vadvise()) will use the libc stub for vadvise(). The headers for this interface are gone. vadvise(2) could be marked as COMPAT_80, but as long as we support ultrix, sunos or aout68k ABI, don't bother with this. Requested by <mrg>

Subsequent changes will be much more interesting. Also, kern_sa.c has received partial cleanup. There's still more to do, though.

1.92.6.1	20-Jan-2011	bouyer	Snapshot of work in progress on a modernised disk quota system: - new quotactl syscall (versionned for backward compat), which takes as parameter a path to a mount point, and a prop_dictionary (in plistref format) describing commands and arguments. For each command, status and data are returned as a prop_dictionary. quota commands features will be added to take advantage of this, exporting quota data or getting quota commands as plists. - new on disk-format storage (all 64bit wide), integrated to metadata for ffs (and playing nicely with wapbl). Quotas are enabled on a ffs filesystem via superblock flags. tunefs(8) can enable or disable quotas. On a quota-enabled filesystem, fsck_ffs(8) will track per-uid/gid block and inode usages, and will check and update quotas in Pass 6. quota usage and limits are stored in unliked files (one for users, one for groups)l fsck_ffs(8) will create the files if needed, or free them if needed. This means that after enabling or disabling quotas on a filesystem; a fsck_ffs(8) run is required. quotacheck(8) is not needed any more, on a unclean shutdown fsck or journal replay will take care of fixing quotas. newfs(8) can create a ready-to-mount quota-enabled filesystem (superblock flags are set and quota inodes are created). Other new features or semantic changes: - default quota datas, applied to users or groups which don't already have a quota entry - per-user/group grace time (instead of a filesystem global one) - 0 really means "nothing allowed at all", not "no limit". If you want "no limit", set the limit to UQUAD_MAX (tools will understand "unlimited" and "-") A quota file is structured as follow: it starts with a header, containing a few per-filesystem values, and the default quota limits. Quota entries are linked together as a simple list, each entry has a pointer (as an offset withing the file) to the next. The header has a pointer to a list of free quota entries, and a hash table of in-use entries. The size of the hash table depends on the filesystem block size (header+hash table should fit in the first block). The file is not sparse and is a multiple of filesystem block size (when the free quota entry list is empty a new filesystem block is allocated). quota entries to not cross filesystem block boundaries. In memory, the kernel keeps a cache of recently used quota entries as a reference to the block number, and offset withing the block. The quota entry itself is keept in the buf cache. fsck_ffs(8), tunefs(8) and newfs(8) supports are completed (with related atf tests :) The kernel can update disk usage and report it via quotactl(2). Todo: enforce quotas limits (limits are not checked by kernel yet) update repquota, edquota and rpc.rquotad to the new world implement compat_50_quotactl ioctl. update quotactl(2) man page fsck_ffs required fixes so that allocating new blocks or inodes will properly update the superblock and cg sumaries. This was not an issue up to now because superblock and cg sumaries check happened last, but now allocations or frees can happen in pass 6.

1.146	18-Jan-2020	kamil	Catch up after getpid/getgid/getuid changes in native ABI in 2008 getpid(), getuid() and getgid() used to call respectively sys_getpid(), sys_getuid() and sys_getgid(). In the BSD4.3 compat mode there was a fallback to call sys_getpid_with_ppid() and related functions. In 2008 the compat ifdef was removed in sys/kern/syscalls.master r. 1.216. For purity reasons we probably shall restore the NetBSD original behavior and implement BSD4.3 one as a compat module, however it is not worth the complexity. Align the netbsd32 compat ABI to native ABI and call functions that return two integers as in BSD4.3.

Subsequent changes will be much more interesting. Also, kern_sa.c has received partial cleanup. There's still more to do, though.

1.92.6.1	20-Jan-2011	bouyer	Snapshot of work in progress on a modernised disk quota system: - new quotactl syscall (versionned for backward compat), which takes as parameter a path to a mount point, and a prop_dictionary (in plistref format) describing commands and arguments. For each command, status and data are returned as a prop_dictionary. quota commands features will be added to take advantage of this, exporting quota data or getting quota commands as plists. - new on disk-format storage (all 64bit wide), integrated to metadata for ffs (and playing nicely with wapbl). Quotas are enabled on a ffs filesystem via superblock flags. tunefs(8) can enable or disable quotas. On a quota-enabled filesystem, fsck_ffs(8) will track per-uid/gid block and inode usages, and will check and update quotas in Pass 6. quota usage and limits are stored in unliked files (one for users, one for groups)l fsck_ffs(8) will create the files if needed, or free them if needed. This means that after enabling or disabling quotas on a filesystem; a fsck_ffs(8) run is required. quotacheck(8) is not needed any more, on a unclean shutdown fsck or journal replay will take care of fixing quotas. newfs(8) can create a ready-to-mount quota-enabled filesystem (superblock flags are set and quota inodes are created). Other new features or semantic changes: - default quota datas, applied to users or groups which don't already have a quota entry - per-user/group grace time (instead of a filesystem global one) - 0 really means "nothing allowed at all", not "no limit". If you want "no limit", set the limit to UQUAD_MAX (tools will understand "unlimited" and "-") A quota file is structured as follow: it starts with a header, containing a few per-filesystem values, and the default quota limits. Quota entries are linked together as a simple list, each entry has a pointer (as an offset withing the file) to the next. The header has a pointer to a list of free quota entries, and a hash table of in-use entries. The size of the hash table depends on the filesystem block size (header+hash table should fit in the first block). The file is not sparse and is a multiple of filesystem block size (when the free quota entry list is empty a new filesystem block is allocated). quota entries to not cross filesystem block boundaries. In memory, the kernel keeps a cache of recently used quota entries as a reference to the block number, and offset withing the block. The quota entry itself is keept in the buf cache. fsck_ffs(8), tunefs(8) and newfs(8) supports are completed (with related atf tests :) The kernel can update disk usage and report it via quotactl(2). Todo: enforce quotas limits (limits are not checked by kernel yet) update repquota, edquota and rpc.rquotad to the new world implement compat_50_quotactl ioctl. update quotactl(2) man page fsck_ffs required fixes so that allocating new blocks or inodes will properly update the superblock and cg sumaries. This was not an issue up to now because superblock and cg sumaries check happened last, but now allocations or frees can happen in pass 6.

1.146	18-Jan-2020	kamil	Catch up after getpid/getgid/getuid changes in native ABI in 2008 getpid(), getuid() and getgid() used to call respectively sys_getpid(), sys_getuid() and sys_getgid(). In the BSD4.3 compat mode there was a fallback to call sys_getpid_with_ppid() and related functions. In 2008 the compat ifdef was removed in sys/kern/syscalls.master r. 1.216. For purity reasons we probably shall restore the NetBSD original behavior and implement BSD4.3 one as a compat module, however it is not worth the complexity. Align the netbsd32 compat ABI to native ABI and call functions that return two integers as in BSD4.3.

In doing so, it removes several XXXSMPs in the MI code, which is good. * Removes the PMC code of ARM XSCALE. * Removes all the pmc.h files. They were all empty, except for ARM XSCALE. * Reorders the x86 PMC code not to rely on the legacy pmc.h file. The definitions are put in sysarch.h. * Removes the kern/sys_pmc.c file, and along with it, the sys_pmc_control and sys_pmc_get_info syscalls. They are marked as OBSOL in kern, netbsd32 and rump. * Removes the pmc_evid_t and pmc_ctr_t types. * Removes all the associated man pages. The sets are marked as obsolete.

1.132	06-Jan-2018	kamil	branches: 1.132.2; Revert vadvise(2) removal This system call was used in legacy Lisp code, that was inherited to modern age and still compiled against supported compat layers (e.g. in clisp, oaklisp, Franz Lisp). It used to instruct the kernel about paging policy (G/C aware, flush etc). Newly compiled code (assuming that it will detect vadvise()) will use the libc stub for vadvise(). The headers for this interface are gone. vadvise(2) could be marked as COMPAT_80, but as long as we support ultrix, sunos or aout68k ABI, don't bother with this. Requested by <mrg>

1.76.4.2	14-May-2008	wrstuden	Per discussion with ad, remove most of the #include <sys/sa.h> lines as they were including sa.h just for the type(s) needed for syscallargs.h. Instead, create a new file, sys/satypes.h, which contains just the types needed for syscallargs.h. Yes, there's only one now, but that may change and it's probably more likely to change if it'd be difficult to handle. :-) Per discussion with matt at n dot o, add an include of satypes.h to sigtypes.h. Upcall handlers are kinda signal handlers, and signalling is the header file that's already included for syscallargs.h that closest matches SA. This shaves about 3000 lines off of the diff of the branch relative to the base. That also represents about 18% of the total before this checkin. I think this reduction is very good thing.
1.76.4.1	10-May-2008	wrstuden	Initial checkin of re-adding SA. Everything except kern_sa.c compiles in GENERIC for i386. This is still a work-in-progress, but this checkin covers most of the mechanical work (changing signalling to be able to accomidate SA's process-wide signalling and re-adding includes of sys/sa.h and savar.h). Subsequent changes will be much more interesting. Also, kern_sa.c has received partial cleanup. There's still more to do, though.

1.91.6.2	09-Feb-2011	bouyer	Regen
1.91.6.1	20-Jan-2011	bouyer	Snapshot of work in progress on a modernised disk quota system: - new quotactl syscall (versionned for backward compat), which takes as parameter a path to a mount point, and a prop_dictionary (in plistref format) describing commands and arguments. For each command, status and data are returned as a prop_dictionary. quota commands features will be added to take advantage of this, exporting quota data or getting quota commands as plists. - new on disk-format storage (all 64bit wide), integrated to metadata for ffs (and playing nicely with wapbl). Quotas are enabled on a ffs filesystem via superblock flags. tunefs(8) can enable or disable quotas. On a quota-enabled filesystem, fsck_ffs(8) will track per-uid/gid block and inode usages, and will check and update quotas in Pass 6. quota usage and limits are stored in unliked files (one for users, one for groups)l fsck_ffs(8) will create the files if needed, or free them if needed. This means that after enabling or disabling quotas on a filesystem; a fsck_ffs(8) run is required. quotacheck(8) is not needed any more, on a unclean shutdown fsck or journal replay will take care of fixing quotas. newfs(8) can create a ready-to-mount quota-enabled filesystem (superblock flags are set and quota inodes are created). Other new features or semantic changes: - default quota datas, applied to users or groups which don't already have a quota entry - per-user/group grace time (instead of a filesystem global one) - 0 really means "nothing allowed at all", not "no limit". If you want "no limit", set the limit to UQUAD_MAX (tools will understand "unlimited" and "-") A quota file is structured as follow: it starts with a header, containing a few per-filesystem values, and the default quota limits. Quota entries are linked together as a simple list, each entry has a pointer (as an offset withing the file) to the next. The header has a pointer to a list of free quota entries, and a hash table of in-use entries. The size of the hash table depends on the filesystem block size (header+hash table should fit in the first block). The file is not sparse and is a multiple of filesystem block size (when the free quota entry list is empty a new filesystem block is allocated). quota entries to not cross filesystem block boundaries. In memory, the kernel keeps a cache of recently used quota entries as a reference to the block number, and offset withing the block. The quota entry itself is keept in the buf cache. fsck_ffs(8), tunefs(8) and newfs(8) supports are completed (with related atf tests :) The kernel can update disk usage and report it via quotactl(2). Todo: enforce quotas limits (limits are not checked by kernel yet) update repquota, edquota and rpc.rquotad to the new world implement compat_50_quotactl ioctl. update quotactl(2) man page fsck_ffs required fixes so that allocating new blocks or inodes will properly update the superblock and cg sumaries. This was not an issue up to now because superblock and cg sumaries check happened last, but now allocations or frees can happen in pass 6.

1.26	18-Jan-2020	kamil	Catch up after getpid/getgid/getuid changes in native ABI in 2008 getpid(), getuid() and getgid() used to call respectively sys_getpid(), sys_getuid() and sys_getgid(). In the BSD4.3 compat mode there was a fallback to call sys_getpid_with_ppid() and related functions. In 2008 the compat ifdef was removed in sys/kern/syscalls.master r. 1.216. For purity reasons we probably shall restore the NetBSD original behavior and implement BSD4.3 one as a compat module, however it is not worth the complexity. Align the netbsd32 compat ABI to native ABI and call functions that return two integers as in BSD4.3.

It used to instruct the kernel about paging policy (G/C aware, flush etc). Newly compiled code (assuming that it will detect vadvise()) will use the libc stub for vadvise(). The headers for this interface are gone. vadvise(2) could be marked as COMPAT_80, but as long as we support ultrix, sunos or aout68k ABI, don't bother with this. Requested by <mrg>

1.41	02-Jan-2020	thorpej	- Eliminate the global "boottime" variable, which was being accessed without any synchronization against changes by e.g. clock_settime(). - Replace with new getbinboottime() / getnanoboottime() / getmicroboottime() functions (naming mirrors that of other time access functions in kern_tc.c). It returns the (maybe-converted) value of timebasebin, which also tracks our estimate of when the system was booted (i.e. the legacy "boottime" was redundant). XXX There needs to be a lockless synchronization mechanism for reading timebasebin, but this is a problem in kern_tc.c that pre-existed these "boottime" changes. At least now the problem is centralized in one location.
1.40	26-May-2018	kamil	branches: 1.40.2; Fix sysctl(3):vm.minaddress in compat_netbsd32(8) Cast minaddress from LP64-specific long (64-bit) to 32-bit long (int). This value is usually 0 or 0+PAGE_SIZE. There is need to change type in order to keep original code functional, without prompting the value with 'long long' or a similar approach. There are more CTLTYPE_LONG with a need for fixes in the compat code: uipc_usrreq.c 1975 CTLTYPE_LONG, "sendspace", 1981 CTLTYPE_LONG, "recvspace", 1987 CTLTYPE_LONG, "sendspace", 1993 CTLTYPE_LONG, "recvspace", vfs_bio.c 1921 CTLTYPE_LONG, "bufmem", 1928 CTLTYPE_LONG, "bufmem_lowater", 1935 CTLTYPE_LONG, "bufmem_hiwater", Sponsored by <The NetBSD Foundation>
1.39	26-May-2018	kamil	Handle vm.maxaddress in compat_netbsd32(8) Return VM_MAXUSER_ADDRESS32 instead of the 64-bit specific address. Use CTLTYPE_INT instead of CTLTYPE_LONG in order to retain the same integer type between 64-bit native kernel and 32-bit emulated program. There probably should be CTLTYPE_LONG32 available for this purpose. On NetBSD/i386: vm.maxaddress=bfeff000 On NetBSD/amd64: vm.maxaddress=7fbfdfeff000 On NetBSD/amd64 running i386 program: vm.maxaddress=fffff000 A 32-bit program on the 64-bit kernel can use larger user space, this difference is on purpose and expected.

A few 'compat' routines that just call standard ones have been deleted. All the 'compat' code compiles (along with the kernels required to test build it). 98% done by automated scripts.

1.18	03-Jul-2005	cube	Make COMPAT_NETBSD32 emulate hw.machine. While it might seem wrong to do so, it introduces breakage because a lot of applications make assumptions from its value. It's especially bad in the sparc64 case, where 64-bits instructions can be used in 32-bits addressing mode. However, there are other means to know the capabilities of the CPU.

1.16	20-Jun-2005	atatat	Change the rest of the sysctl subsystem to use const consistently. The __UNCONST macro is now used only where necessary and the RW macros are gone. Most of the changes here are consumers of the sysctl_createv(9) interface that now takes a pair of const pointers which used not to be.

1.12	04-Dec-2003	atatat	Dynamic sysctl. Gone are the old kern_sysctl(), cpu_sysctl(), hw_sysctl(), vfs_sysctl(), etc, routines, along with sysctl_int() et al. Now all nodes are registered with the tree, and nodes can be added (or removed) easily, and I/O to and from the tree is handled generically. Since the nodes are registered with the tree, the mapping from name to number (and back again) can now be discovered, instead of having to be hard coded. Adding new nodes to the tree is likewise much simpler -- the new infrastructure handles almost all the work for simple types, and just about anything else can be done with a small helper function. All existing nodes are where they were before (numerically speaking), so all existing consumers of sysctl information should notice no difference. PS - I'm sorry, but there's a distinct lack of documentation at the moment. I'm working on sysctl(3/8/9) right now, and I promise to watch out for buses.

Instead, create a new file, sys/satypes.h, which contains just the types needed for syscallargs.h. Yes, there's only one now, but that may change and it's probably more likely to change if it'd be difficult to handle. :-) Per discussion with matt at n dot o, add an include of satypes.h to sigtypes.h. Upcall handlers are kinda signal handlers, and signalling is the header file that's already included for syscallargs.h that closest matches SA. This shaves about 3000 lines off of the diff of the branch relative to the base. That also represents about 18% of the total before this checkin. I think this reduction is very good thing.
1.28.12.1	10-May-2008	wrstuden	Initial checkin of re-adding SA. Everything except kern_sa.c compiles in GENERIC for i386. This is still a work-in-progress, but this checkin covers most of the mechanical work (changing signalling to be able to accomidate SA's process-wide signalling and re-adding includes of sys/sa.h and savar.h).

1.145	18-Jan-2020	kamil	Catch up after getpid/getgid/getuid changes in native ABI in 2008 getpid(), getuid() and getgid() used to call respectively sys_getpid(), sys_getuid() and sys_getgid(). In the BSD4.3 compat mode there was a fallback to call sys_getpid_with_ppid() and related functions. In 2008 the compat ifdef was removed in sys/kern/syscalls.master r. 1.216. For purity reasons we probably shall restore the NetBSD original behavior and implement BSD4.3 one as a compat module, however it is not worth the complexity. Align the netbsd32 compat ABI to native ABI and call functions that return two integers as in BSD4.3.

It used to instruct the kernel about paging policy (G/C aware, flush etc). Newly compiled code (assuming that it will detect vadvise()) will use the libc stub for vadvise(). The headers for this interface are gone. vadvise(2) could be marked as COMPAT_80, but as long as we support ultrix, sunos or aout68k ABI, don't bother with this. Requested by <mrg>

1.76.4.2	14-May-2008	wrstuden	Per discussion with ad, remove most of the #include <sys/sa.h> lines as they were including sa.h just for the type(s) needed for syscallargs.h. Instead, create a new file, sys/satypes.h, which contains just the types needed for syscallargs.h. Yes, there's only one now, but that may change and it's probably more likely to change if it'd be difficult to handle. :-) Per discussion with matt at n dot o, add an include of satypes.h to sigtypes.h. Upcall handlers are kinda signal handlers, and signalling is the header file that's already included for syscallargs.h that closest matches SA. This shaves about 3000 lines off of the diff of the branch relative to the base. That also represents about 18% of the total before this checkin. I think this reduction is very good thing.
1.76.4.1	10-May-2008	wrstuden	Initial checkin of re-adding SA. Everything except kern_sa.c compiles in GENERIC for i386. This is still a work-in-progress, but this checkin covers most of the mechanical work (changing signalling to be able to accomidate SA's process-wide signalling and re-adding includes of sys/sa.h and savar.h). Subsequent changes will be much more interesting. Also, kern_sa.c has received partial cleanup. There's still more to do, though.

1.91.6.2	09-Feb-2011	bouyer	Regen
1.91.6.1	20-Jan-2011	bouyer	Snapshot of work in progress on a modernised disk quota system: - new quotactl syscall (versionned for backward compat), which takes as parameter a path to a mount point, and a prop_dictionary (in plistref format) describing commands and arguments. For each command, status and data are returned as a prop_dictionary. quota commands features will be added to take advantage of this, exporting quota data or getting quota commands as plists. - new on disk-format storage (all 64bit wide), integrated to metadata for ffs (and playing nicely with wapbl). Quotas are enabled on a ffs filesystem via superblock flags. tunefs(8) can enable or disable quotas. On a quota-enabled filesystem, fsck_ffs(8) will track per-uid/gid block and inode usages, and will check and update quotas in Pass 6. quota usage and limits are stored in unliked files (one for users, one for groups)l fsck_ffs(8) will create the files if needed, or free them if needed. This means that after enabling or disabling quotas on a filesystem; a fsck_ffs(8) run is required. quotacheck(8) is not needed any more, on a unclean shutdown fsck or journal replay will take care of fixing quotas. newfs(8) can create a ready-to-mount quota-enabled filesystem (superblock flags are set and quota inodes are created). Other new features or semantic changes: - default quota datas, applied to users or groups which don't already have a quota entry - per-user/group grace time (instead of a filesystem global one) - 0 really means "nothing allowed at all", not "no limit". If you want "no limit", set the limit to UQUAD_MAX (tools will understand "unlimited" and "-") A quota file is structured as follow: it starts with a header, containing a few per-filesystem values, and the default quota limits. Quota entries are linked together as a simple list, each entry has a pointer (as an offset withing the file) to the next. The header has a pointer to a list of free quota entries, and a hash table of in-use entries. The size of the hash table depends on the filesystem block size (header+hash table should fit in the first block). The file is not sparse and is a multiple of filesystem block size (when the free quota entry list is empty a new filesystem block is allocated). quota entries to not cross filesystem block boundaries. In memory, the kernel keeps a cache of recently used quota entries as a reference to the block number, and offset withing the block. The quota entry itself is keept in the buf cache. fsck_ffs(8), tunefs(8) and newfs(8) supports are completed (with related atf tests :) The kernel can update disk usage and report it via quotactl(2). Todo: enforce quotas limits (limits are not checked by kernel yet) update repquota, edquota and rpc.rquotad to the new world implement compat_50_quotactl ioctl. update quotactl(2) man page fsck_ffs required fixes so that allocating new blocks or inodes will properly update the superblock and cg sumaries. This was not an issue up to now because superblock and cg sumaries check happened last, but now allocations or frees can happen in pass 6.

1.37	18-Jan-2020	kamil	Catch up after getpid/getgid/getuid changes in native ABI in 2008 getpid(), getuid() and getgid() used to call respectively sys_getpid(), sys_getuid() and sys_getgid(). In the BSD4.3 compat mode there was a fallback to call sys_getpid_with_ppid() and related functions. In 2008 the compat ifdef was removed in sys/kern/syscalls.master r. 1.216. For purity reasons we probably shall restore the NetBSD original behavior and implement BSD4.3 one as a compat module, however it is not worth the complexity. Align the netbsd32 compat ABI to native ABI and call functions that return two integers as in BSD4.3.

1.6	22-Jun-2015	mrg	add netbsd32 support for nfssvc(2). we do this by defining 5 copyin/out functions that do all the ugly work, are just plain copyin/out for the native system calls, and do the necessary translations for netbsd32. with this i'm able to run 32 bit nfsd and mountd on 64 bit kernel and mount the file systems remotely.

1.58	26-Oct-2022	riastradh	sys: Put externs for time_adjtime and time_adjusted in .h files. time_adjtime: sys/timex.h (defined in ntp code) time_adjusted: sys/timevar.h (defined in non-ntp code) (Not really sure this is a valuable distinction to maintain; there's non-ntp code that uses time_adjtime too.)
1.57	20-Sep-2021	thorpej	Add timerfd system calls to COMPAT_NETBSD32.
1.56	07-Sep-2021	riastradh	sys/compat: Memset zero before copyout. Just in case of uninitialized padding which would lead to kernel stack disclosure. If the compiler can prove the memset redundant then it can optimize it away; otherwise better safe than sorry.
1.55	18-Feb-2021	simonb	In the compat setitimer(2) calls, don't validate which timer is being used since dosetitimer() does this anyway. The compat functions hadn't been updated since ITIMER_MONOTONIC was introduced, so they reported that that ITIMER_MONOTONIC timer was invalid.
1.54	19-Jan-2021	simonb	KNF consistency: No parentheses are needed around the return value.

1.50	30-Oct-2018	riastradh	Paranoia: zero COMPAT_30 ntptimeval and 32-bit ntptimeval too. These structs don't have padding but safer to keep the code structured the same way between the various ntp_gettimes in case anyone makes more copypasta of it for future updates.

1.40	03-Apr-2010	njoly	Move most clock_getres syscall code, except for coypout call, to a new clock_getres1() function which can be used by emulations. Adjust all clock_getres syscalls to now make of use it.
1.39	29-Mar-2010	njoly	Convert linux/linux32/netbsd32 clock_settime syscalls, to use the common clock_settime1() function.

1.31	21-Dec-2007	dsl	Fix prototypes used when NTP is not in use. Pointed out by Robert Swindells.
1.30	20-Dec-2007	dsl	Convert all the system call entry points from: int foo(struct lwp l, void v, register_t retval) to: int foo(struct lwp l, const struct foo_args uap, register_t retval) Fixup compat code to not write into 'uap' and (in some cases) to actually pass a correctly formatted 'uap' structure with the right name to the next routine. A few 'compat' routines that just call standard ones have been deleted. All the 'compat' code compiles (along with the kernels required to test build it). 98% done by automated scripts.

1.26	16-Mar-2007	dsl	remove all the double (and triple) casts used to convert 32bit userspace pointers to and from 64bit kernel pointers. Instead use the defines NETBSD32PTR64(p32) to read a 32bit pointer and (the new) NETBSD32PTR32(p32,p64) to write a 32bit pointer throughout. The 32bit pointer is now a struct to enforce the above. amd64 (with linux emul) and sparc64 will both compile (when the arch stuff goes in soon), and amd64 still runs some i386 binaries.
1.25	04-Mar-2007	christos	branches: 1.25.2; 1.25.4; 1.25.6; Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.

1.22	07-Jun-2006	kardel	merge FreeBSD timecounters from branch simonb-timecounters - struct timeval time is gone time.tv_sec -> time_second - struct timeval mono_time is gone mono_time.tv_sec -> time_uptime - access to time via {get,}{micro,nano,bin}time() get* versions are fast but less precise - support NTP nanokernel implementation (NTP API 4) - further reading: Timecounter Paper: http://phk.freebsd.dk/pubs/timecounter.pdf NTP Nanokernel: http://www.eecis.udel.edu/~mills/ntp/html/kern.html

1.15	05-Dec-2005	kleink	Sync with kern_time.c rev. 1.98: - make settime take timespec. - pass struct proc down so that we can log a detailed message.
1.14	11-Nov-2005	simonb	Call nanotime() directly, instead of doing the microtime()/TIMEVAL_TO_TIMESPEC() dance.
1.13	23-Oct-2005	cube	Implement a few changes needed to properly resolve PR#30924, as discussed in the PR. - introduce sys/timevar.h to hold kernel-specific stuff relevant to sys/time.h. Ideally, timevar.h would contain all (or almost) of the #ifdef _KERNEL part of time.h, but that's a pretty big and tedious change to make. For now, it will contain only the prototypes I introduced when working on COMPAT_NETBSD32. - split copyinout_t into copyin_t and copyout_t, it makes prototypes more explicit about the meaning of a given argument. Suggested by yamt@. - move copyinout_t definition in sys/time.h to systm.h as copyin_t and copyout_t - make everything uses the new types and include the proper headers at the proper places.
1.12	19-Aug-2005	christos	branches: 1.12.2; Fix lossage I created with the 64 bit ino_t change.
1.11	23-Jul-2005	cube	Implement the timer_create(2) family of syscalls.
1.10	11-Jul-2005	cube	Split sys_getitimer and sys_setitimer to make it possible to share the relevant code with the COMPAT_NETBSD32 version, and make the latter use the new functions. This fixes netbsd32_setitimer() which had drifted from the native syscall and did not work properly anymore.
1.9	31-May-2005	christos	branches: 1.9.2; - add const - avoid shadowed variables.
1.8	26-Feb-2005	perry	nuke trailing whitespace
1.7	14-Nov-2004	atatat	branches: 1.7.4; 1.7.6; Wrap TIMEVAL_TO_TIMESPEC and TIMESPEC_TO_TIMEVAL macros in do { ... } while(/CONSTCOND/0) so that they can be used unadorned in if/else blocks, etc. This means that you now have to put a ; at the end of the "call" to these macros.

1.5	18-Jan-2003	thorpej	branches: 1.5.2; Merge the nathanw_sa branch.
1.4	23-Oct-2002	scw	In preparation for COMPAT_NETBSD32 on SH-5: - The MD netbsd32_machdep.h header now defines the 32-bit pointer type instead of using u_int32_t everywhere, - The MD netbsd32_machdep.h header now defines a macro (at least on current implementations) which converts a 32-bit pointer to its 64-bit equivalent, - Change the MI code to utilise the above two items in all the right places, - Implement netbsd32___sigaction_sigtramp(). Tested on Sparc64 by Matt Green.

1.49.12.2	25-Sep-2018	pgoyette	Additional use of NTP function pointers, since the NTP code might not exist in the kernel. (NTP is not (yet) a module, so we don't need to use the MP-safe mechanism.)
1.49.12.1	11-Sep-2018	pgoyette	Move the NTP compat_30 and compat_50 routines into the version-specific modules.
1.49.6.2	21-Jun-2023	martin	Pull up following revision(s) (requested by riastradh in ticket #1839): sys/compat/common/kern_time_30.c: revision 1.6 sys/compat/netbsd32/netbsd32_time.c: revision 1.50 Paranoia: zero COMPAT_30 ntptimeval and 32-bit ntptimeval too. These structs don't have padding but safer to keep the code structured the same way between the various ntp_gettimes in case anyone makes more copypasta of it for future updates.

1.3	19-Jan-2021	simonb	Also print mmap return value and error code #ifdef DEBUG_MMAP.
1.2	07-Jan-2020	mrg	branches: 1.2.8; don't check the value of retval in netbsd32_mmap() if sys_mmap() was not successful.
1.1	24-Dec-2018	mrg	branches: 1.1.2; 1.1.6; move mmap(), compat 40 mount(), pipe() and getfh() into their own files as the implementation is non trivial or is compat. mark old mount() properly instead of manually #if'ing ito to ENOSYS.

1.26	05-Dec-2021	msaitoh	s/sytle/style/ in comment.
1.25	07-Sep-2021	riastradh	sys/compat: Memset zero before copyout. Just in case of uninitialized padding which would lead to kernel stack disclosure. If the compiler can prove the memset redundant then it can optimize it away; otherwise better safe than sorry.
1.24	15-Oct-2020	rin	wait4(2): make error paths match with that of native wait4(2): https://nxr.netbsd.org/xref/src/sys/kern/kern_exit.c#720
1.23	23-Sep-2016	skrll	branches: 1.23.8; 1.23.20; Add netbsd32_clock_getcpuclockid2 and netbsd32_wait6 functions
1.22	03-Nov-2012	njoly	branches: 1.22.14; 1.22.18; Move rusage computation to a new getrusage1() function. Adjust all compat/emulations to make use of it.
1.21	04-Nov-2009	rmind	branches: 1.21.12; 1.21.22; do_sys_wait(): fix previous by checking for ru != NULL. Noticed by Onno van der Linden. Also, remove redundant arguments (seems that was_zombie was not used since rev 1.177 ?).
1.20	11-Jan-2009	christos	merge christos-time_t
1.19	29-May-2008	mrg	branches: 1.19.6; 1.19.12; remove clause #3 from my license where there are no other copyright holders involved.
1.18	24-Apr-2008	ad	branches: 1.18.2; 1.18.4; Merge proc::p_mutex and proc::p_smutex into a single adaptive mutex, since we no longer need to guard against access from hardware interrupt handlers. Additionally, if cloning a process with CLONE_SIGHAND, arrange to have the child process share the parent's lock so that signal state may be kept in sync. Partially addresses PR kern/37437.
1.17	20-Dec-2007	dsl	branches: 1.17.6; 1.17.8; Convert all the system call entry points from: int foo(struct lwp l, void v, register_t retval) to: int foo(struct lwp l, const struct foo_args uap, register_t retval) Fixup compat code to not write into 'uap' and (in some cases) to actually pass a correctly formatted 'uap' structure with the right name to the next routine. A few 'compat' routines that just call standard ones have been deleted. All the 'compat' code compiles (along with the kernels required to test build it). 98% done by automated scripts.
1.16	08-Dec-2007	dsl	branches: 1.16.4; ANSIfy most of the function definitions in sys/compat (but not ndis). All by the magic of sed ...
1.15	07-May-2007	dsl	branches: 1.15.6; 1.15.8; 1.15.16; Split sys_wait4() so that compat code can fiddle with the returned 'status' and 'rusage' without having to copy data to/from stackgap buffers. The old split (find_stopped_child) could be removed. amd64 seems to run netbsd32, linux and linux32 emulations. sparc64 compiles.
1.14	18-Mar-2007	dsl	Change all the NETBSD32PTR64(SCARG(uap, xxx))) to SCARG_P32(uap, xxx).
1.13	16-Mar-2007	dsl	remove all the double (and triple) casts used to convert 32bit userspace pointers to and from 64bit kernel pointers. Instead use the defines NETBSD32PTR64(p32) to read a 32bit pointer and (the new) NETBSD32PTR32(p32,p64) to write a 32bit pointer throughout. The 32bit pointer is now a struct to enforce the above. amd64 (with linux emul) and sparc64 will both compile (when the arch stuff goes in soon), and amd64 still runs some i386 binaries.
1.12	04-Mar-2007	christos	branches: 1.12.2; 1.12.4; 1.12.6; Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.
1.11	09-Feb-2007	ad	branches: 1.11.2; Merge newlock2 to head.
1.10	11-Dec-2005	christos	branches: 1.10.20; merge ktrace-lwp.
1.9	19-Aug-2005	christos	Fix lossage I created with the 64 bit ino_t change.
1.8	22-Jul-2005	cube	Remove duplication of code for netbsd32_wait4() by using stackgap(9).
1.7	10-Jul-2005	cube	Report changes from sys_wait4().
1.6	14-Feb-2003	dsl	branches: 1.6.2; 1.6.18; Use find_stopped_child() and proc_free() in compat wait() code to avoid code duplication. (approved by christos)
1.5	18-Jan-2003	thorpej	Merge the nathanw_sa branch.
1.4	23-Oct-2002	scw	branches: 1.4.2; In preparation for COMPAT_NETBSD32 on SH-5: - The MD netbsd32_machdep.h header now defines the 32-bit pointer type instead of using u_int32_t everywhere, - The MD netbsd32_machdep.h header now defines a macro (at least on current implementations) which converts a 32-bit pointer to its 64-bit equivalent, - Change the MI code to utilise the above two items in all the right places, - Implement netbsd32___sigaction_sigtramp(). Tested on Sparc64 by Matt Green.
1.3	28-Jul-2002	jdolecek	Convert to use p_opptr rather than p_oppid. Part of fix for security/14444 by David Sainty.
1.2	13-Nov-2001	lukem	branches: 1.2.8; 1.2.10; add RCSIDs (including regeneration of files as appropriate)
1.1	08-Feb-2001	mrg	branches: 1.1.2; 1.1.4; 1.1.6; split up netbsd32_netbsd.c into 9 new files, leaving only those syscalls that have no special interpretations besides simple syscall args conversion.

1.146	20-May-2024	christos	branches: 1.146.2; Rename dup3110 to dup3100 to match historical practice for NetBSD-11, because we already have kevent100. Fix compat_dup3 to belong in compat_100 not compat_110.
1.145	19-May-2024	christos	version dup3
1.144	30-Jul-2023	rin	COMPAT_NETBSD32: Add support for epoll(2).
1.143	30-Jul-2023	rin	COMPAT_NETBSD32: Add support for memfd_create(2).
1.142	29-Jul-2023	rin	COMPAT_NETBSD32: Catch up with sys___kevent100() addition. XXX Add epoll_* and memfd_create.
1.141	20-Sep-2021	thorpej	Add the eventfd(2) system call to COMPAT_NETBSD32.
1.140	20-Sep-2021	thorpej	Add timerfd system calls to COMPAT_NETBSD32.
1.139	10-Oct-2020	rin	Teach about getrandom(2) to COMPAT_NETBSD32.
1.138	16-May-2020	christos	Add ACL support for FFS. From FreeBSD.
1.137	26-Apr-2020	thorpej	Mirror the change made to native -- move futex calls to 166-168.
1.136	26-Apr-2020	thorpej	Add a NetBSD native futex implementation, mostly written by riastradh@. Map the COMPAT_LINUX futex calls to the native ones.
1.135	22-Apr-2020	thorpej	Remove _lwp_gettid(2) system call. This problem is going to be solved another way. (Note: this call was never exposed in libc, so we can just recycle the syscall number.)
1.134	04-Apr-2020	thorpej	branches: 1.134.2; Add support for lazily generating a "global thread ID" for a LWP. This identifier uniquely identifies an LWP across the entire system, and will be used in future improvements in user-space synchronization primitives. (Test disabled and libc stub not included intentionally so as to avoid multiple libc version bumps.)
1.133	12-Mar-2020	pgoyette	Split out the quota code from the rest of compat_netbsd32 module. This allows loading of compat_netbsd32 on kernels that don't have ``options QUOTA'' enabled.
1.132	07-Mar-2020	pgoyette	Properly mark netbsd32_compat_43 syscalls that are directly implemented by calling their compat_43 equivalents. With these changes, and with built-in versions of COMPAT_NETBSD32, COMPAT_NOMID, and COMPAT_09, I can now run a netbsd-0.9 statically linked i386 (32-bit) version of /bin/ls on a 9.99.x amd64 host! Addresses PR kern/55047 but more changes coming to handle non-built-in modules. XXX pullup-9
1.131	18-Jan-2020	kamil	Catch up after getpid/getgid/getuid changes in native ABI in 2008 getpid(), getuid() and getgid() used to call respectively sys_getpid(), sys_getuid() and sys_getgid(). In the BSD4.3 compat mode there was a fallback to call sys_getpid_with_ppid() and related functions. In 2008 the compat ifdef was removed in sys/kern/syscalls.master r. 1.216. For purity reasons we probably shall restore the NetBSD original behavior and implement BSD4.3 one as a compat module, however it is not worth the complexity. Align the netbsd32 compat ABI to native ABI and call functions that return two integers as in BSD4.3.
1.130	04-Nov-2019	rin	branches: 1.130.2; netbsd32_size_t should be used instead of size_t for argument of 32-bit syscalls: - netbsd32___getvfsstat90: bufsize - netbsd32___fhstatvfs190: fh_size No need to pullup, since these syscalls were introduced after branch of netbsd-9.
1.129	04-Nov-2019	rin	For netbsd32_readlinkat(2), bufsize is netbsd_size_t, not size_t. Since bufsize is the last argument, this affects only LP64EB. XXX pullup to netbsd-9, -8, and -7
1.128	22-Sep-2019	christos	Add a new member to struct vfsstat and grow the unused members The new member is caled f_mntfromlabel and it is the dkw_wname of the corresponding wedge. This is now used by df -W to display the mountpoint name as NAME=
1.127	18-Jun-2019	christos	branches: 1.127.2; Add ifdef for quota and include the syscall numbers header
1.126	18-Jun-2019	christos	use option quota
1.125	27-Jan-2019	pgoyette	Merge the [pgoyette-compat] branch
1.124	24-Dec-2018	mrg	move mmap(), compat 40 mount(), pipe() and getfh() into their own files as the implementation is non trivial or is compat. mark old mount() properly instead of manually #if'ing ito to ENOSYS.
1.123	31-Jul-2018	rjs	Add getsockopt2().
1.122	12-Jul-2018	maxv	Remove the kernel PMC code. Sent yesterday on tech-kern@. This change: * Removes "options PERFCTRS", the associated includes, and the associated ifdefs. In doing so, it removes several XXXSMPs in the MI code, which is good. * Removes the PMC code of ARM XSCALE. * Removes all the pmc.h files. They were all empty, except for ARM XSCALE. * Reorders the x86 PMC code not to rely on the legacy pmc.h file. The definitions are put in sysarch.h. * Removes the kern/sys_pmc.c file, and along with it, the sys_pmc_control and sys_pmc_get_info syscalls. They are marked as OBSOL in kern, netbsd32 and rump. * Removes the pmc_evid_t and pmc_ctr_t types. * Removes all the associated man pages. The sets are marked as obsolete.
1.121	10-May-2018	christos	branches: 1.121.2; add {send,recv}mmsg
1.120	06-Jan-2018	kamil	branches: 1.120.2; Revert vadvise(2) removal This system call was used in legacy Lisp code, that was inherited to modern age and still compiled against supported compat layers (e.g. in clisp, oaklisp, Franz Lisp). It used to instruct the kernel about paging policy (G/C aware, flush etc). Newly compiled code (assuming that it will detect vadvise()) will use the libc stub for vadvise(). The headers for this interface are gone. vadvise(2) could be marked as COMPAT_80, but as long as we support ultrix, sunos or aout68k ABI, don't bother with this. Requested by <mrg>
1.119	19-Dec-2017	kamil	Drop SYS_vadvise The (o)vadvise syscall is dummy since the beginning of NetBSD. It is an obsolete remnant from the old UNIX. Sponsored by <The NetBSD Foundation>
1.118	19-Dec-2017	kamil	Drop SYS_sbrk sbrk - change data segment size This syscall is dummy since the inception of the project. Sponsored by <The NetBSD Foundation>
1.117	19-Dec-2017	kamil	Drop the sstk(2) syscall stub sstk - change stack section size This functionality has never been implemented and is a remnant from 16-bit UNIX. This stub appeared with the first NetBSD commit. Sponsored by <The NetBSD Foundation>
1.116	19-Dec-2017	kamil	Sync syscalls.master in compat_netbsd32(8) with kern/syscalls.master ___lwp_part60 removed 'const' from the ts argument. 'const struct timespec ts' -> 'struct timespec ts' Sponsored by <The NetBSD Foundation>
1.115	19-Oct-2016	skrll	branches: 1.115.8; PR kern/51514: ptrace(2) fails for 32-bit process on 64-bit kernel Updated from the original patch in the PR by me.

1.111	01-Dec-2015	pgoyette	Prepare for new compat_netbsd32_mqueue module to be split out of compat_netbsd32. Refactor the COMPAT_50 code related to mqueue, and update the syscall definitions. Remove dependency on mqueue from the compat_netbsd32 module (the new module will gain this dependency). Continuation of work on PR kern/50489
1.110	01-Dec-2015	pgoyette	Mark the nfssvc syscall as auto-loadable from the compat_netbsd32_nfssrv module (to be committed shortly).
1.109	23-Jun-2015	dholland	Don't reference netbsd32_nfssvc unless NFSSERVER is defined. Fixes PR 49994.
1.108	22-Jun-2015	mrg	add netbsd32 support for nfssvc(2). we do this by defining 5 copyin/out functions that do all the ugly work, are just plain copyin/out for the native system calls, and do the necessary translations for netbsd32. with this i'm able to run 32 bit nfsd and mountd on 64 bit kernel and mount the file systems remotely.

1.95	08-Apr-2012	martin	branches: 1.95.2; Rework posix_spawn locking and memory management: - always provide a vmspace for the new proc, initially borrowing from proc0 (this part fixes PR 46286) - increase parallelism between parent and child if arguments allow this, avoiding a potential deadlock on exec_lock - add a new flag for userland to request old (lockstepped) behaviour for better error reporting - adapt test cases to the previous two and add a new variant to test the diagnostics flag - fix a few memory (and lock) leaks - provide netbsd32 compat
1.94	10-Mar-2012	joerg	P1003_1B_SEMAPHORE is no longer optional.
1.93	08-Mar-2012	joerg	Add entry for _ksem_timedwait.
1.92	19-Feb-2012	rmind	Make SA calls obsolete (use stubs in kern case, as libc needs them for now).
1.91	01-Feb-2012	dholland	branches: 1.91.2; Update compat_netbsd32 for new quotactl.
1.90	01-Feb-2012	dholland	Change the syscall API for quotas over to the new non-proplib one. - struct vfs_quotactl_args -> struct quotactl_args - add sys/stdint.h to sys/quotactl.h for clean userland build - install sys/quotactl.h in /usr/include - update set lists for same - add new marshalling code in libquota - add new unmarshalling code in vfs_syscalls.c - discard proplib interpreter code in vfs_quotactl.c - add dispatching code for the 14 quotactl ops in vfs_quotactl.c - mark the proplib quotactl syscall obsolete - add a new syscall number for the new quotactl syscall - change the name of the syscall to __quotactl() - remove the decl of the old quotactl from quota/quotaprop.h - add a decl of the new quotactl to sys/quotactl.h - update the libc build - update ktruss - remove proplib marshalling code from libquota - update copy of syscall table in gdb ppc sources - hack rumphijack to accomodate new quotactl name (as I recall, pooka wanted such a name change to simplify something, but I don't really see what/how) This change appears to require a kernel version bump for rumpish reasons.
1.89	31-Jan-2012	matt	Add the *at syscalls and other missing syscalls.
1.88	08-Nov-2011	njoly	branches: 1.88.4; Add kqueue1(2) support.
1.87	31-Aug-2011	njoly	branches: 1.87.2; Add dup3 syscall support.
1.86	05-Jul-2011	njoly	Add pipe2 syscall now needed for popen(3).
1.85	06-Mar-2011	bouyer	merge the bouyer-quota2 branch. This adds a new on-disk format to store disk quota usage and limits, integrated with ffs metadata. Usage is checked by fsck_ffs (no more quotacheck) and is covered by the WAPBL journal. Enabled with kernel option QUOTA2 (added where QUOTA was enabled in kernel config files), turned on with tunefs(8) on a per-filesystem basis. mount_mfs(8) can also turn quotas on. See http://mail-index.netbsd.org/tech-kern/2011/02/19/msg010025.html for details.
1.84	02-Mar-2010	pooka	branches: 1.84.2; 1.84.4; 1.84.6; Kill fs_nfs.h and #ifdef NFS by making getfh() support unconditional and nfssvc unsupport unconditional. nfs server was just a fancy NOP anyway for all except Ultrix. I know I'm boring but I couldn't imagine why someone would want to run an Ultrix nfs server (and I also doubt that it would work anymore with all the changes to fs exporting etc).
1.83	02-Mar-2010	pooka	-fs_lfs.h
1.82	02-Mar-2010	pooka	Remove lfs syscall support from compat. I can't really imagine anyone wanting to run lfs megamaid as a e.g. FreeBSD binary. Besides, the real action has been in fcntl() for >5 years now. The only place where the compat syscalls might have made the tiniest bit of sense was netbsd32, but they were unimplemented there.
1.81	14-Dec-2009	matt	branches: 1.81.2; Merge from matt-nb5-mips64
1.80	17-May-2009	pooka	pad -> PAD
1.79	16-Mar-2009	njoly	Fix dev_t alignment, by not using the new 64bit value directly but rather a 32bit aligned version (netbsd32_dev_t = netbsd32_uint64). ok by cube@.
1.78	26-Feb-2009	christos	fix kernel build with no options NTP
1.77	13-Jan-2009	pooka	branches: 1.77.2; Convert the syscalls.master to a format from which it is easier to parse and generate the compat name and basename (e.g. __stat50 and stat). Use this to autogenerate __RENAME()'s to the rump_syscalls header so that they can be called e.g. rump_sys_socket() instead of rump_sys___socket30().
1.76	13-Jan-2009	pooka	UNIMPL police: remove pseudo-prototypes
1.75	11-Jan-2009	christos	merge christos-time_t
1.74	22-Nov-2008	mrg	branches: 1.74.4; implement netbsd32__sched_setparam(), netbsd32__sched_getparam(), netbsd32__sched_setaffinity() and netbsd32__sched_getaffinity().
1.73	19-Nov-2008	ad	Make the emulations, exec formats, coredump, NFS, and the NFS server into modules. By and large this commit: - shuffles header files and ifdefs - splits code out where necessary to be modular - adds module glue for each of the components - adds/replaces hooks for things that can be installed at runtime
1.72	14-Nov-2008	ad	Replace semid_t with intptr_t. No function change. This is a libc/kernel private interface and so the name change should not affect any third party code.
1.71	12-Nov-2008	ad	Remove LKMs and switch to the module framework, pass 1. Proposed on tech-kern@.
1.70	15-Oct-2008	wrstuden	branches: 1.70.2; 1.70.4; Merge wrstuden-revivesa into HEAD.
1.69	24-Apr-2008	ad	branches: 1.69.2; 1.69.4; 1.69.8; - Retire SYCALL_MPSAFE. With the exceptions of darwin and irix emulations, all system calls are now MPSAFE. - Remove unneeded acquire/release of kernel_lock.
1.68	24-Feb-2008	martin	branches: 1.68.2; Desupport compatibility for the old posix_fadvise syscall per yamt's request and just ignore it.
1.67	27-Jan-2008	martin	branches: 1.67.2; 1.67.6; Catch up with versioning of posix_fadvise
1.66	26-Jan-2008	dsl	Add a wrapper for posix_fadvise()
1.65	19-Jan-2008	dsl	Add netbsd32 wrapper for sys_mremap(), compiles, and assuming the mmap() wrapper is ok, it should work! I presume the kernel knows not to map above 4GB though....
1.64	17-Dec-2007	dsl	Remove all the 'const'. Although the fields might be 32bit pointers to constant data, the 'const' applies to the field itself - which is stupid.
1.63	07-Dec-2007	ad	branches: 1.63.4; Add: _lwp_setname, _lwp_getname, _lwp_ctl.
1.62	09-Nov-2007	dsl	branches: 1.62.2; Add arguments to sys_syscall and sys___syscall. Use MI wrappers for them in netbsd32. Change prefix for constants from netbsd32 to NETBSD32 (used in #defines etc).
1.61	15-Aug-2007	ad	branches: 1.61.2; 1.61.6; 1.61.8; Changes to make ktrace LKM friendly and reduce ifdef KTRACE. Proposed on tech-kern.
1.60	07-Aug-2007	ad	- Fix a bug with _lwp_park() where if the computed wakeup time was under 1 microsecond into the future, the thread could enter an untimed sleep. - Change the signature of _lwp_park() to accept an lwpid_t and second hint pointer, but do so in a way that remains compatible with older pthread libraries. This can be used to wake another thread before the calling thread goes asleep, saving at least one syscall + involuntary context switch. This turns out to be a fairly large win on the condvar benchmarks that I have tried. - Mark some more syscalls MP safe.
1.59	04-Mar-2007	christos	branches: 1.59.2; 1.59.6; 1.59.10; 1.59.14; fix fallout from caddr_t changes.
1.58	04-Mar-2007	christos	Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.
1.57	19-Feb-2007	cube	Mark MPSAFE the syscalls that are not translated (and of course, only when the native syscall is itself marked MPSAFE).
1.56	18-Feb-2007	cube	Add missing lwp syscalls. Put them all together into a new file, netbsd32_lwp.c, and remove remaining traces of SA. This still needs some MD (and possibly MI, depending on the chosen solution) changes to actually work.
1.55	09-Feb-2007	ad	branches: 1.55.2; Merge newlock2 to head.
1.54	09-Nov-2006	cube	- Make better use of COMPAT_XX type in syscalls.master - Remove useless (thanks to COMPAT_XX behaviour) #ifdefs in syscalls.master - Make netbsd32_compat_43.c compiled per COMPAT_LINUX32 because the latter needs stuff from it. Fixes Perry's PR#34951.
1.53	01-Sep-2006	matt	branches: 1.53.2; 1.53.4; Don't conditionalize *sys_ptrace. The lack of sys_ptrace will be dealt with differently.
1.52	30-Aug-2006	cube	Protect netbsd32_ptrace with options PTRACE.
1.51	31-Jul-2006	martin	Step 1 to make filehandles completely opaque to userland
1.50	13-Jul-2006	pavel	do not protect the getfh syscall by #if defined(NFS) \|\| defined(NFSSERVER). The native syscall also isn't.
1.49	13-Jul-2006	martin	Fix alignement problems for fhandle_t, exposed by gcc4.1. While touching all vptofh/fhtovp functions, get rid of VFS_MAXFIDSIZ, version the getfh(2) syscall and explicitly pass the size available in the filehandle from userland. Discussed on tech-kern, with lots of help from yamt (thanks!).
1.48	26-Jun-2006	mrg	version the socket(2) syscall. for compat30 socket, we use EPROTONOSUPPORT instead of EAFNOSUPPORT. from pavel@ with a little bit of clean up from myself. XXX: netbsd32 (and perhaps other emulations) should be able XXX: to call the standard socket calls for this i think, but XXX: revisit this at another time.
1.47	31-May-2006	drochner	branches: 1.47.2; support ntp_gettime again compile tested by Havard Eidnes
1.46	29-May-2006	drochner	Remove emulation of ntp_gettime. In preparation for "timecounters" we will change "struct ntptimeval", so some translation would be necessary. ntp_gettine is considered dispensable, the only userland program known to use it is "ntptime".
1.45	05-May-2006	cube	branches: 1.45.2; Follow on fhstat(2) versioning. While there, add sys_posix_fadvise (no emulation needed there).
1.44	29-Mar-2006	cube	Implement the _lwp* and sa_* families of syscalls, using the newly introduced hooks in the native code.
1.43	06-Mar-2006	cube	branches: 1.43.2; 1.43.4; Implement the SysV IPC family of syscalls.
1.42	05-Mar-2006	cube	branches: 1.42.2; Implement the ksem_* family of syscalls.
1.41	11-Dec-2005	christos	branches: 1.41.4; 1.41.6; merge ktrace-lwp.
1.40	23-Oct-2005	cube	- Split sys_kevent into kevent1 so that it can be used by COMPAT_NETBSD32 code. - To achieve COMPAT_NETBSD32 compatibility, introduce a parameter to kevent1 that points to functions that do the actual copyin/copyout operations. This is similar to what was done in FreeBSD by Paul Saab. - Add the COMPAT_NETBSD32 definitions and hooks.
1.39	19-Aug-2005	christos	branches: 1.39.2; Fix lossage I created with the 64 bit ino_t change.
1.38	19-Aug-2005	christos	64 bit inode changes.
1.37	23-Jul-2005	cube	Implement __sigtimedwait(2).
1.36	23-Jul-2005	cube	Implement the timer_create(2) family of syscalls.
1.35	12-Jul-2005	cube	Add the xattr(2) family of syscalls. Just like the extattr(2) family, they're waiting for an actual FS back-end to be tested, but are still straightforward enough.
1.34	11-Jul-2005	cube	Add rasctl(2). Thanks to the regression tests for that syscall, I was able to discover the bugs in netbsd32_setitimer() and netbsd32_execve().
1.33	10-Jul-2005	cube	Add support for fsync_range(2).
1.32	10-Jul-2005	cube	Implement __clone(2).
1.31	09-Jul-2005	cube	Implement pselect(2) and pollts(2).
1.30	08-Jul-2005	cube	Add mlockall(2) and munlockall(2).
1.29	08-Jul-2005	cube	Implement the extattr(3) family of syscalls. XXX However, those remain untested as there are currently no backend for XXX extattr(9) in NetBSD.
1.28	04-Jul-2005	cube	branches: 1.28.2; Implement uuidgen(2).
1.27	30-May-2005	chs	track change to swapctl args in kern/syscalls.master.
1.26	17-Jun-2004	cube	o Add support for the statvfs family of syscalls (statvfs1, fstatvfs1, fhstatvfs1 and getvfsstat) o Move the statfs family out of netbsd32_fs.c and netbsd32_netbsd.c to netbsd_compat_20.c, compiled with COMPAT_20 Reviewed by christos@.
1.25	25-Oct-2003	chs	allow COMPAT_SUNOS without COMPAT_43.
1.24	13-Oct-2003	fvdl	Define compat_16 as valid prefix; define the 1.6 compat sigreturn.
1.23	18-Jan-2003	thorpej	branches: 1.23.2; Merge the nathanw_sa branch.
1.22	23-Oct-2002	scw	In preparation for COMPAT_NETBSD32 on SH-5: - The MD netbsd32_machdep.h header now defines the 32-bit pointer type instead of using u_int32_t everywhere, - The MD netbsd32_machdep.h header now defines a macro (at least on current implementations) which converts a 32-bit pointer to its 64-bit equivalent, - Change the MI code to utilise the above two items in all the right places, - Implement netbsd32___sigaction_sigtramp(). Tested on Sparc64 by Matt Green.
1.21	29-Apr-2002	mrg	build the netbsd32_compat* objects into libcompat.a, so they are available to emulations not just netbsd itself. rename the compat_10 functions to match everything else. fixes a problem reported by julian coleman.
1.20	30-May-2001	mrg	branches: 1.20.2; use _KERNEL_OPT.
1.19	10-Apr-2001	kleink	Slight indentation nit.
1.18	02-Feb-2001	mrg	branches: 1.18.2; add lchflags, issetugid, utrace, reserves for [gs]etcontext, and sched/SA.
1.17	27-Jan-2001	thorpej	getpid(2) is MP-safe.
1.16	09-Dec-2000	mycroft	Add the %% separators.
1.15	30-Nov-2000	jdolecek	always include netbsd32_ntp_adjtime(), LKMify
1.14	07-Aug-2000	bjh21	Changes to syscalls.master to exclude ntp_adjtime(2) entirely if NTP is not defined. Changes to other files will follow in a moment.
1.13	09-Jul-2000	mrg	- massive warning fix fest. - fix pread/pwrite return values (plus some other syscalls that looked similarly broken). - prototypes and clean up for netbsd32_ioctl.c now getpw*() works under compat32!
1.12	31-Jan-2000	christos	__semctl13 -> ____semctl13
1.11	30-Dec-1999	eeh	Update to 32-bit compatibility routines.
1.10	11-Oct-1999	eeh	branches: 1.10.2; Add netbsd32_compat_14.c Rename everything from compat_netbsd32 -> netbsd32 so we don't have silly names like compat_14_compat_netbsd32_sys_shmctl().
1.9	12-Jul-1999	kleink	branches: 1.9.2; XSH5: change function signature to `void *sbrk(intptr_t)'.

1.2	26-Aug-1998	mrg	make oreboot work.
1.1	26-Aug-1998	mrg	add a 32-bit compatibility module for the sparc64 port, so it can run NetBSD/sparc binaries with a LP64 kernel.

1.69.4.3	28-Sep-2008	skrll	Re-add SA syscalls.
1.69.4.2	14-May-2008	wrstuden	Per discussion with ad, remove most of the #include <sys/sa.h> lines as they were including sa.h just for the type(s) needed for syscallargs.h. Instead, create a new file, sys/satypes.h, which contains just the types needed for syscallargs.h. Yes, there's only one now, but that may change and it's probably more likely to change if it'd be difficult to handle. :-) Per discussion with matt at n dot o, add an include of satypes.h to sigtypes.h. Upcall handlers are kinda signal handlers, and signalling is the header file that's already included for syscallargs.h that closest matches SA. This shaves about 3000 lines off of the diff of the branch relative to the base. That also represents about 18% of the total before this checkin. I think this reduction is very good thing.
1.69.4.1	10-May-2008	wrstuden	Initial checkin of re-adding SA. Everything except kern_sa.c compiles in GENERIC for i386. This is still a work-in-progress, but this checkin covers most of the mechanical work (changing signalling to be able to accomidate SA's process-wide signalling and re-adding includes of sys/sa.h and savar.h). Subsequent changes will be much more interesting. Also, kern_sa.c has received partial cleanup. There's still more to do, though.

1.84.6.2	09-Feb-2011	bouyer	Proper definitions for quotactl
1.84.6.1	20-Jan-2011	bouyer	Snapshot of work in progress on a modernised disk quota system: - new quotactl syscall (versionned for backward compat), which takes as parameter a path to a mount point, and a prop_dictionary (in plistref format) describing commands and arguments. For each command, status and data are returned as a prop_dictionary. quota commands features will be added to take advantage of this, exporting quota data or getting quota commands as plists. - new on disk-format storage (all 64bit wide), integrated to metadata for ffs (and playing nicely with wapbl). Quotas are enabled on a ffs filesystem via superblock flags. tunefs(8) can enable or disable quotas. On a quota-enabled filesystem, fsck_ffs(8) will track per-uid/gid block and inode usages, and will check and update quotas in Pass 6. quota usage and limits are stored in unliked files (one for users, one for groups)l fsck_ffs(8) will create the files if needed, or free them if needed. This means that after enabling or disabling quotas on a filesystem; a fsck_ffs(8) run is required. quotacheck(8) is not needed any more, on a unclean shutdown fsck or journal replay will take care of fixing quotas. newfs(8) can create a ready-to-mount quota-enabled filesystem (superblock flags are set and quota inodes are created). Other new features or semantic changes: - default quota datas, applied to users or groups which don't already have a quota entry - per-user/group grace time (instead of a filesystem global one) - 0 really means "nothing allowed at all", not "no limit". If you want "no limit", set the limit to UQUAD_MAX (tools will understand "unlimited" and "-") A quota file is structured as follow: it starts with a header, containing a few per-filesystem values, and the default quota limits. Quota entries are linked together as a simple list, each entry has a pointer (as an offset withing the file) to the next. The header has a pointer to a list of free quota entries, and a hash table of in-use entries. The size of the hash table depends on the filesystem block size (header+hash table should fit in the first block). The file is not sparse and is a multiple of filesystem block size (when the free quota entry list is empty a new filesystem block is allocated). quota entries to not cross filesystem block boundaries. In memory, the kernel keeps a cache of recently used quota entries as a reference to the block number, and offset withing the block. The quota entry itself is keept in the buf cache. fsck_ffs(8), tunefs(8) and newfs(8) supports are completed (with related atf tests :) The kernel can update disk usage and report it via quotactl(2). Todo: enforce quotas limits (limits are not checked by kernel yet) update repquota, edquota and rpc.rquotad to the new world implement compat_50_quotactl ioctl. update quotactl(2) man page fsck_ffs required fixes so that allocating new blocks or inodes will properly update the superblock and cg sumaries. This was not an issue up to now because superblock and cg sumaries check happened last, but now allocations or frees can happen in pass 6.
