1.3	15-Nov-2003	thorpej	branches: 1.3.8; 1.3.10; We have CVS; there is no reason to make .bak files when generating the syscall tables.
1.2	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.
1.1	03-Sep-1996	mycroft	branches: 1.1.2; 1.1.64; Give every emulation its own Makefile for the syscall table.

1.1.2.2	10-Dec-1996	mycroft	From trunk: Give all the emulations a consistent Makefile.
1.1.2.1	03-Sep-1996	mycroft	file Makefile was added on branch netbsd-1-2 on 1996-12-10 08:38:25 +0000
1.3.10.1	19-Mar-2005	yamt	sync with head. xen and whitespace. xen part is not finished.

1.5.126.1	18-May-2014	rmind	sync with head
1.5.120.1	20-Aug-2014	tls	Rebase to HEAD as of a few days ago.
1.5.110.1	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")
1.7	27-Jan-2019	pgoyette	Merge the [pgoyette-compat] branch
1.6	17-Nov-2014	uebayasi	branches: 1.6.18; 1.6.20; Define compat modules (but without dependencies yet).
1.5	19-Nov-2008	ad	branches: 1.5.26; 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
1.4	09-Dec-2000	jdolecek	branches: 1.4.122; 1.4.126; 1.4.132; 1.4.136; split ecoff specific code to separate file ultrix_exec_ecoff.c
1.3	07-Jan-1996	jonathan	branches: 1.3.30; Add '/emul/ultrix' pathname processing to Ultrix emulation, and move Ultrix syscalls that require that processing out of ultrix_misc.c to ultrix_pathname.c.
1.2	26-Dec-1995	jonathan	Add emulation of Ultrix select: before calling native sys_select(), limit the number of FDs to select on to the maximum supported by NetBSD -- which is as many FDs as the emul_ultrix process can have open, anyway. Add emulation of Ultrix getmnt(2) in ultrix_fs.c Add partial emulation of Ultrix tty ioctl()s in ultrix_ioctl.c, derived from compat/sunos/sunos_ioctl.c. Ultrix libc's ``isatty()'' now works in compat_emul processes.
1.1	20-Sep-1995	thorpej	Add common file lists, similar to what the other emulation modules use.
1.3.30.1	13-Dec-2000	bouyer	Sync with HEAD (for UBC fixes).

1.6.20.1	10-Jun-2019	christos	Sync with HEAD
1.6.18.1	12-Mar-2018	pgoyette	Update dependencies for modules when they are built-in. Now we don't (or at least, shouldn't) need reminders in the GENERIC config files about which module options require other options. Update branch status doc accordingly.
1.7	19-Sep-1995	thorpej	Obsolete; use the one in /sys/kern
1.6	02-Dec-1994	dean	new sysent version.
1.5	30-Jun-1994	cgd	fix a botch, and gen syscall files
1.4	30-Jun-1994	cgd	fix up for new ID format, and consistency
1.3	29-Jun-1994	cgd	New RCS ID's, take two. they're more aesthecially pleasant, and use 'NetBSD'
1.2	15-Jun-1994	glass	much works but untested w/new fs. expect more tomorrow
1.1	02-Jun-1994	glass	first swipe at ultrix compat. expect many bug fixes. very related to compat/sunos
1.4	01-Nov-2002	jdolecek	set nsysent to 512 (oh well, just three syscalls too many for 256)
1.3	18-Dec-1998	drochner	branches: 1.3.20; remove compat_xxx dependencies where they don't belong
1.2	22-Jan-1998	mycroft	This doesn't actually use COMPAT_10.
1.1	23-Nov-1994	dean	changes for new sysent structure (from J. Stone)
1.3.20.1	11-Nov-2002	nathanw	Catch up to -current
1.58	03-Mar-2019	pgoyette	The compat_09_{get,set}domainname() syscalls should not be defined based on existence of COMPAT_09. Make them modular instead, and reference the compat_09 module.
1.57	27-Jan-2019	pgoyette	Merge the [pgoyette-compat] branch
1.56	06-Jan-2018	kamil	branches: 1.56.2; 1.56.4; 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>
1.55	19-Dec-2017	kamil	compat/ultrix: Drop SYS_vadvise The (o)vadvise syscall is dummy since the beginning of NetBSD. Sponsored by <The NetBSD Foundation>
1.54	19-Dec-2017	kamil	compat/ultrix: Drop SYS_sbrk sbrk - change data segment size This syscall is dummy since the inception of the project. Sponsored by <The NetBSD Foundation>
1.53	19-Dec-2017	kamil	compat ultrix: Drop the sstk(2) syscall sstk(2) has never been implemented by the NetBSD kernel. Sponsored by <The NetBSD Foundation>
1.52	07-Nov-2013	njoly	Fix dup/dup2/dup3 argument types (u_int -> int).
1.51	02-Mar-2010	pooka	branches: 1.51.10; 1.51.20; 1.51.24; 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).
1.50	17-Jan-2009	he	branches: 1.50.4; Adapt to the state after the recent time_t change. Type changes: timeval -> timeval50 itimerval -> itimerval50 rusage -> rusage50 and use of the compat_50 calls where appropriate. Untested, but at least it builds. Discussed with christos@
1.49	13-Jan-2009	pooka	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().
1.48	13-Jan-2009	pooka	UNIMPL police (two mount syscalls with the same signature?!?)
1.47	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
1.46	19-Jun-2008	hans	branches: 1.46.2; 1.46.4; include <sys/sched.h> for cpuset_t
1.45	23-Apr-2008	ad	branches: 1.45.2; 1.45.4; 1.45.6; -SYCALL_MPSAFE
1.44	04-Mar-2007	christos	branches: 1.44.36; 1.44.38; Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.
1.43	09-Feb-2007	ad	branches: 1.43.2; Merge newlock2 to head.
1.42	13-Jul-2006	pavel	branches: 1.42.4; use the COMPAT_30 getfh.
1.41	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.
1.40	11-Dec-2005	christos	branches: 1.40.4; 1.40.8; 1.40.16; merge ktrace-lwp.
1.39	26-Feb-2005	perry	branches: 1.39.4; nuke trailing whitespace
1.38	18-Jan-2003	thorpej	branches: 1.38.2; 1.38.10; 1.38.12; Merge the nathanw_sa branch.
1.37	30-May-2001	mrg	use _KERNEL_OPT.
1.36	27-Jan-2001	thorpej	branches: 1.36.2; getpid(2) is MP-safe.
1.35	09-Dec-2000	mycroft	Add the %% separators.
1.34	09-Dec-2000	mycroft	Add the %% separators.
1.33	30-Nov-2000	jdolecek	LKMify
1.32	30-Jul-1999	drochner	branches: 1.32.2; emulate fcntl(F_SETLK) & Co. (seti@home works now:-)
1.31	12-Jul-1999	kleink	XSH5: change function signature to `void *sbrk(intptr_t)'.
1.30	09-Feb-1999	christos	branches: 1.30.2; 1.30.4; const poisoning and CHECK_ALT_CREAT fixes.
1.29	18-Dec-1998	drochner	remove compat_xxx dependencies where they don't belong
1.28	10-Dec-1998	christos	Defopt COMPAT_43
1.27	03-Oct-1998	drochner	Use a private implementation of sys_sigvec(). Ultrix uses an sv_flags bit unknown to NetBSD and sigaction1() does (now?) complain about it.
1.26	26-Sep-1998	drochner	Make Ultrix emulation private functions for sigreturn and sigsuspend because the NetBSD implementation differs now.
1.25	25-Jun-1998	thorpej	defopt NFSSERVER
1.24	19-Feb-1998	thorpej	Include the NFS option header.
1.23	14-Feb-1998	kleink	Use sys___posix_{chown,fchown}() instead of sys_{chown,fchown}().
1.22	16-Oct-1997	christos	ostat -> stat43
1.21	13-Jun-1997	thorpej	Use compat_12_sys_swapon().
1.20	09-Jun-1997	jonathan	Emulate RISC Ultrix cacheflush() and cachectl() syscalls on mips.
1.19	09-Jun-1997	jonathan	Declare ultrix_sys_symshs(). Ultrix uses the standard (BRL?) hack to implement sysV shm using one system call.
1.18	31-Jan-1997	thorpej	branches: 1.18.2; NFSCLIENT -> NFS
1.17	03-Sep-1996	mycroft	branches: 1.17.2; Define execv() and execve() consistently across emulations. Do path name translation.
1.16	23-Jun-1996	mycroft	Catch up with setre[ug]id() changes.
1.15	07-Jan-1996	jonathan	branches: 1.15.4; Add '/emul/ultrix' pathname processing to Ultrix emulation, and move Ultrix syscalls that require that processing out of ultrix_misc.c to ultrix_pathname.c.
1.14	26-Dec-1995	jonathan	Add emulation of ultrix mount(2). Sufficient to NFS-mount filesystems using a NetBSD kernel in an ultrix root filesystem. Move wait emulation to the old (v7) wait syscall number, as that's what the Ultrix ufs_mount binary uses.
1.13	26-Dec-1995	jonathan	Fix ultrix_sys_select() entry.
1.12	26-Dec-1995	jonathan	Add emulation of Ultrix select: before calling native sys_select(), limit the number of FDs to select on to the maximum supported by NetBSD -- which is as many FDs as the emul_ultrix process can have open, anyway. Add emulation of Ultrix getmnt(2) in ultrix_fs.c Add partial emulation of Ultrix tty ioctl()s in ultrix_ioctl.c, derived from compat/sunos/sunos_ioctl.c. Ultrix libc's ``isatty()'' now works in compat_emul processes.
1.11	07-Oct-1995	mycroft	Prefix names of system call implementation functions with `sys_'.
1.10	01-Jun-1995	mellon	Clear up name conflict between Ultrix syscall 103 and 139.
1.9	01-Feb-1995	mellon	Fix up some incompatibilities and some indentation botches
1.8	02-Dec-1994	dean	fixed typo
1.7	01-Dec-1994	dean	added sigreturn
1.6	23-Nov-1994	dean	changes for new sysent structure (from J. Stone)
1.5	01-Aug-1994	glass	ultrix_{get,set}info from Arne H Juul <arnej@dsl.unit.no>
1.4	29-Jun-1994	cgd	branches: 1.4.2; New RCS ID's, take two. they're more aesthecially pleasant, and use 'NetBSD'
1.3	22-Jun-1994	glass	update for getdtablesize change, and track compat_sunos
1.2	15-Jun-1994	glass	much works but untested w/new fs. expect more tomorrow
1.1	02-Jun-1994	glass	first swipe at ultrix compat. expect many bug fixes. very related to compat/sunos
1.4.2.1	01-Aug-1994	cgd	From trunk.
1.15.4.2	10-Dec-1996	mycroft	From trunk: Do execv() and execve() path name translation consistently across emulations.
1.15.4.1	10-Dec-1996	mycroft	From trunk: Implement setre[ug]id() for real.
1.17.2.1	14-Jan-1997	thorpej	Snapshot of work-in-progress, committed to private branch. These changes implement machine-independent root device and file system selection. Notable features: - All ports behave in a consistent manner regarding root device selection. - No more "options GENERIC"; all kernels have the ability to boot with RB_ASKNAME to select root device and file system type. - Root file system type can be wildcarded; a machine-independent function will try all possible file systems for the selected root device until one succeeds. - If the root file system fails to mount, the operator will be given the chance to select a new root device and file system type, rather than having the machine simply panic. - nfs_mountroot() no longer panics if any part of the NFS mount process fails; it now returns an error, giving the operator a chance to recover. - New, more consistent, config(8) grammar. The constructs: config netbsd swap generic config netbsd root on nfs have been replaced with: config netbsd root on ? type ? config netbsd root on ? type nfs Additionally, the operator may select or wildcard root file system type in the kernel configuration file: config netbsd root on cd0a type cd9660 config(8) now requires that a "root" specification be made. "root" may be wired down or wildcarded. "swap" and "dump" specifications are optional, and follow previous semantics. - config(8) has a new "file-system" keyword, used to configure file systems into the kernel. Eventually, this will be used to generate the default vfssw[]. - "options NFSCLIENT" is obsolete, and is replaced by "file-system NFS". "options NFSSERVER" still exists, since NFS server support is independent of the NFS file system client. - sys/arch/<foo>/<foo>/swapgeneric.c is no longer used, and will be removed; all information is now generated by config(8). As of this commit, all ports except arm32 have been updated to use the new setroot(). Only SPARC, i386, and Alpha ports have been tested at this time. Port masters should test these changes on their ports, and report any problems back to me. More changes are on their way, including RB_ASKNAME support in nfs_mountroot() (to prompt for server address and path) and, potentially, the ability to select rarp/bootparam or bootp in nfs_mountroot().
1.18.2.1	12-Feb-1997	mrg	initial work for dynamic swap additions.
1.30.4.1	02-Aug-1999	thorpej	Update from trunk.
1.30.2.1	31-Jan-2000	he	Pull up revision 1.32 (requested by mhitch): Emulate Ultrix fcntl(F_SETLK) & Co. so the Ultrix seti@home client works.

1.45.4.3	23-Jun-2008	wrstuden	Sync w/ -current. 34 merge conflicts to follow.
1.45.4.2	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.
1.45.4.1	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.

1.49	06-May-2008	ad	branches: 1.49.2; 1.49.8; 1.49.16; 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.
1.48	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.
1.47	30-Apr-2008	jmmv	Fix build of these files after the vfs_trybusy change. Apply the same modification done in compat/common/vfs_syscalls_20.c:1.27.
1.46	30-Jan-2008	ad	branches: 1.46.6; 1.46.8; 1.46.10; PR kern/37706 (forced unmount of file systems is unsafe): - Do reference counting for 'struct mount'. Each vnode associated with a mount takes a reference, and in turn the mount takes a reference to the vfsops. - Now that mounts are reference counted, replace the overcomplicated mount locking inherited from 4.4BSD with a recursable rwlock.
1.45	27-Dec-2007	christos	make this compile again.
1.44	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.

1.2	26-Dec-1995	jonathan	Add emulation of ultrix mount(2). Sufficient to NFS-mount filesystems using a NetBSD kernel in an ultrix root filesystem. Move wait emulation to the old (v7) wait syscall number, as that's what the Ultrix ufs_mount binary uses.
1.1	26-Dec-1995	jonathan	Add emulation of Ultrix select: before calling native sys_select(), limit the number of FDs to select on to the maximum supported by NetBSD -- which is as many FDs as the emul_ultrix process can have open, anyway. Add emulation of Ultrix getmnt(2) in ultrix_fs.c Add partial emulation of Ultrix tty ioctl()s in ultrix_ioctl.c, derived from compat/sunos/sunos_ioctl.c. Ultrix libc's ``isatty()'' now works in compat_emul processes.

1.49.2.2	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.
1.49.2.1	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.

1.57.4.1	21-Dec-2017	snj	Pull up following revision(s) (requested by maxv in ticket #434): sys/compat/ultrix/ultrix_fs.c: revision 1.58 Fix uninitialized pointer, found by Mootja. Not a surprise in untested code.
1.40	09-Feb-2022	andvar	fix various typos in comments.
1.39	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.
1.38	23-Apr-2019	msaitoh	branches: 1.38.2; KNF. No functional change.
1.37	08-Oct-2016	maxv	branches: 1.37.8; 1.37.16; Uninitialized var, found by mootja; not tested, but obvious enough
1.36	14-Dec-2009	matt	branches: 1.36.22; 1.36.40; 1.36.44; Merge from matt-nb5-mips64
1.35	21-Mar-2008	ad	branches: 1.35.4; 1.35.6; 1.35.22; Catch up with descriptor handling changes. See kern_descrip.c revision 1.173 for details.
1.34	05-Jan-2008	dsl	branches: 1.34.6; 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.
1.33	27-Dec-2007	christos	make this compile again.
1.32	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.
1.31	01-Jun-2007	he	branches: 1.31.8; 1.31.14; 1.31.16; 1.31.20; Fallout from the interface ioctl changes: OSIOCGIFADDR -> OOSIOCGIFADDR OSIOCGIFDSTADDR -> OOSIOCGIFDSTADDR OSIOCGIFNETMASK -> OOSIOCGIFNETMASK Also, one instance of needing to include <net/if.h> before <compat/sys/sockio.h> due to use of IFNAMSIZ in the latter. Discussed with christos.
1.30	29-May-2007	christos	Add a sockaddr_storage member to "struct ifreq" maintaining backwards compatibility with the older ioctls. This avoids stack smashing and abuse of "struct sockaddr" when ioctls placed "struct sockaddr_foo's" that were longer than "struct sockaddr". XXX: Some of the emulations might be broken; I tried to add code for them but I did not test them.
1.29	09-Feb-2007	ad	branches: 1.29.6; 1.29.8; Merge newlock2 to head.
1.28	11-Dec-2005	christos	branches: 1.28.20; merge ktrace-lwp.

1.24	21-Apr-2004	simonb	ANSIfy, some KNF.
1.23	29-Jun-2003	fvdl	branches: 1.23.2; Back out the lwp/ktrace changes. They contained a lot of colateral damage, and need to be examined and discussed more.
1.22	29-Jun-2003	simonb	Fix 'struct lwp *' lossage.
1.21	07-May-2003	christos	sort the ioctl's so we can see what we've implemented and what we have not.
1.20	21-Mar-2003	dsl	Change 'data' argument to fo_ioctl and fo_fcntl from 'caddr_t' to 'void *'. Avoids a lot of casting and removes the need for some line breaks. Removed a load of (caddr_t) casts from calls to copyin/copyout as well. (approved by christos - he has a plan to remove caddr_t...)
1.19	18-Jan-2003	thorpej	Merge the nathanw_sa branch.
1.18	13-Nov-2001	lukem	add RCSIDs (including regeneration of files as appropriate)
1.17	14-Jun-2001	thorpej	branches: 1.17.2; 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.
1.16	30-May-2001	mrg	use _KERNEL_OPT.
1.15	29-Nov-2000	jdolecek	branches: 1.15.2; LKMify
1.14	30-Mar-2000	augustss	Kill register declarations.

1.12	25-Jun-1998	thorpej	defopt COMPAT_SUNOS
1.11	25-Jun-1998	thorpej	defopt COMPAT_ULTRIX
1.10	25-May-1997	jonathan	lint: add prototypes for termio/termios emul conversions and ioctl handlers.
1.9	05-May-1997	jonathan	NetBSD doesn't have VSWTCH, so we can't emulate it; clarify. (see PR#2793).
1.8	06-Apr-1997	jonathan	* Fix typo in SIOGIFCONF handling. * Change explicit SunOS-compat ioctl codes to Ultrix-compat codes.
1.7	13-Oct-1996	christos	Backout previous kprintf change.
1.6	10-Oct-1996	christos	printf -> kprintf, sprintf -> ksprintf
1.5	09-Oct-1996	thorpej	Merge the netbsd-1-2 branch back into the mainline.
1.4	13-Jun-1996	jonathan	Fix typos in SUSP and DSUSP mapping when setting Ultrix posixmode tty attributes (was 112 and 113, should be 12 and 13).
1.3	07-Apr-1996	jonathan	branches: 1.3.4; Remove gcc -Wall lint from ultrix emulation.- Mostly adding explicit != comparison to "if (error = copyin/out( ... ))". Fix comment glitch in ultrix_fs.c
1.2	04-Jan-1996	jonathan	Rewrite (a copy of) the emul-sunos termio/termios emulation code to emulate Ultrix termio/termios instead. Ultrix termio c_cc has separate VMIM/VTIME attributes, and the Ultrix termios c_cc is a strict superset of Ultrix termio c_cc. The termios-only c_cc indices are all changed, relative to SunOS.
1.1	26-Dec-1995	jonathan	Add emulation of Ultrix select: before calling native sys_select(), limit the number of FDs to select on to the maximum supported by NetBSD -- which is as many FDs as the emul_ultrix process can have open, anyway. Add emulation of Ultrix getmnt(2) in ultrix_fs.c Add partial emulation of Ultrix tty ioctl()s in ultrix_ioctl.c, derived from compat/sunos/sunos_ioctl.c. Ultrix libc's ``isatty()'' now works in compat_emul processes.
1.3.4.3	10-Sep-1996	thorpej	Back out previos change (typo fix) by request from Jonathan Stone; the change fixed a typo in an #ifdef, but the code within the #ifdef is broken and doesn't compile. For more details, "grep XXX ultrix_ioctl.c".
1.3.4.2	08-Sep-1996	jonathan	Fix typo (CMOPAT_ULTRIX -> COMPAT_ULTRIX) around code that uses the Ultrix termios VSWITCH to set the native VSWITCH. (#ifdef'ed to support a future merge with other 4.3BSD compat tty code, e.g., SunOS.)
1.3.4.1	13-Jun-1996	jonathan	pull up fix for SUSP and DSUSP from main branch

1.35.22.1	09-Sep-2009	matt	Change to use fixed sized types.
1.35.6.2	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.
1.35.6.1	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.

1.125	10-Aug-2018	pgoyette	branches: 1.125.4; 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
1.124	06-May-2018	kamil	branches: 1.124.2; 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>
1.123	09-Jan-2018	maya	branches: 1.123.2; 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.
1.122	19-Feb-2012	rmind	branches: 1.122.32; Remove COMPAT_SA / KERN_SA. Welcome to 6.99.3! Approved by core@.
1.121	07-Jul-2010	chs	branches: 1.121.8; 1.121.12; many changes for COMPAT_LINUX: - update the linux syscall table for each platform. - support new-style (NPTL) linux pthreads on all platforms. clone() with CLONE_THREAD uses 1 process with many LWPs instead of separate processes. - move the contents of sys__lwp_setprivate() into a new lwp_setprivate() and use that everywhere. - update linux_release[] and linux32_release[] to "2.6.18". - adjust placement of emul fork/exec/exit hooks as needed and adjust other emul code to match. - convert all struct emul definitions to use named initializers. - change the pid allocator to allow multiple pids to refer to the same proc. - remove a few fields from struct proc that are no longer needed. - disable the non-functional "vdso" code in linux32/amd64, glibc works fine without it. - fix a race in the futex code where we could miss a wakeup after a requeue operation. - redo futex locking to be a little more efficient.

1.118	17-Jan-2009	he	branches: 1.118.4; Adapt to the state after the recent time_t change. Type changes: timeval -> timeval50 itimerval -> itimerval50 rusage -> rusage50 and use of the compat_50 calls where appropriate. Untested, but at least it builds. Discussed with christos@
1.117	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

1.109	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.
1.108	13-May-2007	dsl	branches: 1.108.8; 1.108.14; 1.108.16; 1.108.20; Delete fom stackgap lines that seem to have got left in.

1.99	26-Mar-2005	fvdl	branches: 1.99.2; 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.
1.98	26-Feb-2005	perry	branches: 1.98.2; nuke trailing whitespace
1.97	25-Jan-2005	drochner	Hmm - vax is different. sendsig_sigcontext() is for __mips only. Should fix build error found by Havard Eidnes.
1.96	24-Jan-2005	drochner	branches: 1.96.2; use sendsig_sigcontext() directly instead of the generic sendsig()
1.95	27-Oct-2004	david	branches: 1.95.4; Bounds check syscall arguments where appropriate
1.94	25-Apr-2004	matt	Constify a few read-only arrays/variables.
1.93	21-Apr-2004	simonb	ANSIfy, some KNF.
1.92	20-Dec-2003	fvdl	branches: 1.92.2; Put back Emmanuel's sigfilter hooks, as decided by Core.
1.91	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.
1.90	05-Dec-2003	jdolecek	back the sigfilter emulation hook change off
1.89	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)
1.88	27-Oct-2003	simonb	Fix bogus uninitialised warnings.
1.87	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.
1.86	07-Aug-2003	agc	Move UCB-licensed code from 4-clause to 3-clause licence. Patches provided by Joel Baker in PR 22364, verified by myself.
1.85	29-Jun-2003	fvdl	branches: 1.85.2; Back out the lwp/ktrace changes. They contained a lot of colateral damage, and need to be examined and discussed more.
1.84	29-Jun-2003	simonb	Fix 'struct lwp *' lossage.
1.83	29-Jan-2003	atatat	Cull unused variables. Sigh. PS - Cross compilers are cool.
1.82	28-Jan-2003	atatat	No need to pick a "default address" for mmap in compat code, since we merely call sys_mmap() at the end anyway, and that will pick the address for us, if it's needed. Likewise for checking if /dev/zero is being mapped.
1.81	18-Jan-2003	thorpej	Merge the nathanw_sa branch.
1.80	01-Nov-2002	jdolecek	set struct emul's nsysent to compat SYS_NSYSENT, not SYS_MAXSYSCALL
1.79	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.
1.78	06-Sep-2002	gehenna	Merge the gehenna-devsw branch into the trunk. This merge changes the device switch tables from static array to dynamically generated by config(8). - All device switches is defined as a constant structure in device drivers. - The new grammer ``device-major'' is introduced to ``files''. device-major <prefix> char <num> [block <num>] [<rules>] - All device major numbers must be listed up in port dependent majors.<arch> by using this grammer. - Added the new naming convention. The name of the device switch must be <prefix>_[bc]devsw for auto-generation of device switch tables. - The backward compatibility of loading block/character device switch by LKM framework is broken. This is necessary to convert from block/character device major to device name in runtime and vice versa. - The restriction to assign device major by LKM is completely removed. We don't need to reserve LKM entries for dynamic loading of device switch. - In compile time, device major numbers list is packed into the kernel and the LKM framework will refer it to assign device major number dynamically.
1.77	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.
1.76	16-Mar-2002	christos	branches: 1.76.4; 1.76.6; get rid of STACKGAP* shit.
1.75	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.
1.74	13-Nov-2001	lukem	add RCSIDs (including regeneration of files as appropriate)
1.73	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).
1.72	17-Sep-2001	jdolecek	g/c dead code
1.71	18-Jun-2001	christos	branches: 1.71.2; 1.71.4; Add an e_trapsignal member to struct emul, so that emulated processes can send the appropriate signal depending on the trap type.
1.70	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.
1.69	30-May-2001	mrg	use _KERNEL_OPT.
1.68	15-Jan-2001	thorpej	branches: 1.68.2; Grok __HAVE_MINIMAL_EMUL and __HAVE_SYSCALL_INTERN.

1.66	16-Dec-2000	jdolecek	adapt to recent struct emul changes
1.65	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()
1.64	09-Dec-2000	jdolecek	split ecoff specific code to separate file ultrix_exec_ecoff.c
1.63	01-Dec-2000	jdolecek	make LKM safe
1.62	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
1.61	21-Nov-2000	jdolecek	restructure struct emul and execsw, in preparation to make emulations LKMable: * move all exec-type specific information from struct emul to execsw[] and provide single struct emul per emulation * elf: - kern/exec_elf32.c:probe_funcs[] is gone, execsw[] how has one entry per emulation and contains pointer to respective probe function - interp is allocated via MALLOC() rather than on stack - elf_args structure is allocated via MALLOC() rather than malloc() * ecoff: the per-emulation hooks moved from alpha and mips specific code to OSF1 and Ultrix compat code as appropriate, execsw[] has one entry per emulation supporting ecoff with appropriate probe function * the makecmds/probe functions don't set emulation, pointer to emulation is part of appropriate execsw[] entry * constify couple of structures
1.60	19-Nov-2000	simonb	Update extern declarations of {hpux,ultrix}_syscallnames for change to e_syscallnames in struct emul. Untested on HP, but should be ok.

1.57	28-Apr-2000	simonb	branches: 1.57.4; The size of the members of struct ultrix_utsname were nothing like reality - adjust and fill in "version" the same way that some other compat routines do. An Ultrix "uname -a" returns something meaninful now instead of just "NetBSD ".
1.56	30-Mar-2000	augustss	Kill register declarations.
1.55	28-Mar-2000	simonb	Centralise the declarations of cpu_model, machine, machine_arch, osrelease, and ostype and remove "extern char foo[];" (for hostname and domainname too). Also delete redunctant decl of boottime in kern_info_43.c.
1.54	26-Mar-2000	kleink	Merge parts of chs-ubc2 into the trunk: * Remove the casts to vaddr_t from the round_page() and trunc_page() macros to make them type-generic, which is necessary i.e. to operate on file offsets without truncating them. * In due course, cast pointer arguments to these macros to an appropriate integral type (paddr_t, vaddr_t). Originally done by Chuck Silvers, updated by myself.

1.51	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.

Add emulation of Ultrix getmnt(2) in ultrix_fs.c Add partial emulation of Ultrix tty ioctl()s in ultrix_ioctl.c, derived from compat/sunos/sunos_ioctl.c.

1.23.4.1	10-Dec-1996	mycroft	From trunk: sys/dir.h -> sys/dirent.h
1.28.2.1	14-Jan-1997	thorpej	Snapshot of work-in-progress, committed to private branch. These changes implement machine-independent root device and file system selection. Notable features: - All ports behave in a consistent manner regarding root device selection. - No more "options GENERIC"; all kernels have the ability to boot with RB_ASKNAME to select root device and file system type. - Root file system type can be wildcarded; a machine-independent function will try all possible file systems for the selected root device until one succeeds. - If the root file system fails to mount, the operator will be given the chance to select a new root device and file system type, rather than having the machine simply panic. - nfs_mountroot() no longer panics if any part of the NFS mount process fails; it now returns an error, giving the operator a chance to recover. - New, more consistent, config(8) grammar. The constructs: config netbsd swap generic config netbsd root on nfs have been replaced with: config netbsd root on ? type ? config netbsd root on ? type nfs Additionally, the operator may select or wildcard root file system type in the kernel configuration file: config netbsd root on cd0a type cd9660 config(8) now requires that a "root" specification be made. "root" may be wired down or wildcarded. "swap" and "dump" specifications are optional, and follow previous semantics. - config(8) has a new "file-system" keyword, used to configure file systems into the kernel. Eventually, this will be used to generate the default vfssw[]. - "options NFSCLIENT" is obsolete, and is replaced by "file-system NFS". "options NFSSERVER" still exists, since NFS server support is independent of the NFS file system client. - sys/arch/<foo>/<foo>/swapgeneric.c is no longer used, and will be removed; all information is now generated by config(8). As of this commit, all ports except arm32 have been updated to use the new setroot(). Only SPARC, i386, and Alpha ports have been tested at this time. Port masters should test these changes on their ports, and report any problems back to me. More changes are on their way, including RB_ASKNAME support in nfs_mountroot() (to prompt for server address and path) and, potentially, the ability to select rarp/bootparam or bootp in nfs_mountroot().

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.

1.112.4.2	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.
1.112.4.1	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.

With the merge of the [pgoyette-compat] branch there is no longer a "compat" module; instead we have lots of version-specific compat_xx modules.

1.36	17-Jan-2009	he	branches: 1.36.2; Adapt to the state after the recent time_t change. Type changes: timeval -> timeval50 itimerval -> itimerval50 rusage -> rusage50 and use of the compat_50 calls where appropriate. Untested, but at least it builds. Discussed with christos@
1.35	24-Jun-2008	ad	branches: 1.35.4; 1.35.12; Replace references to getsock/getvnode.
1.34	21-Mar-2008	ad	branches: 1.34.4; 1.34.6; 1.34.8; Catch up with descriptor handling changes. See kern_descrip.c revision 1.173 for details.
1.33	05-Jan-2008	dsl	branches: 1.33.6; 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.
1.32	27-Dec-2007	christos	make this compile again.
1.31	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.
1.30	08-Dec-2007	pooka	branches: 1.30.4; Remove cn_lwp from struct componentname. curlwp should be used from on. The NDINIT() macro no longer takes the lwp parameter and associates the credentials of the calling thread with the namei structure.
1.29	27-Nov-2007	dogcow	branches: 1.29.2; more VFS_STATVFS(x,y,z) fallout; change them to VFS_STATVFS(x,y). (hi, pooka!)
1.28	25-Apr-2007	matt	branches: 1.28.6; 1.28.8; 1.28.14; Make this compile again (after stackgap removal)
1.27	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.
1.26	04-Mar-2007	christos	branches: 1.26.2; 1.26.4; Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.

1.20	21-Apr-2004	christos	Replace the statfs() family of system calls with statvfs(). Retain binary compatibility.
1.19	07-Aug-2003	agc	Move UCB-licensed code from 4-clause to 3-clause licence. Patches provided by Joel Baker in PR 22364, verified by myself.
1.18	29-Jun-2003	fvdl	branches: 1.18.2; Back out the lwp/ktrace changes. They contained a lot of colateral damage, and need to be examined and discussed more.
1.17	29-Jun-2003	simonb	Fix 'struct lwp *' lossage.
1.16	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
1.15	18-Jan-2003	thorpej	Merge the nathanw_sa branch.
1.14	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.
1.13	13-Nov-2001	lukem	add RCSIDs (including regeneration of files as appropriate)
1.12	14-Jun-2001	thorpej	branches: 1.12.2; 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.
1.11	01-Dec-2000	jdolecek	branches: 1.11.2; 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
1.10	30-Mar-2000	augustss	Kill register declarations.
1.9	05-May-1999	thorpej	branches: 1.9.2; 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.
1.8	09-Feb-1999	christos	branches: 1.8.4; const poisoning and CHECK_ALT_CREAT fixes.
1.7	09-Aug-1998	perry	bzero->memset, bcopy->memcpy, bcmp->memcmp
1.6	25-May-1997	jonathan	lint: add prototype for static local function ultrixstatfs().
1.5	14-Oct-1996	mhitch	Now needs sys/proc.h since compat/common/compat_util.h doesn't anymore.
1.4	29-Sep-1996	jonathan	Fix cut-and-paste (ouap vs ap) bugs so the previous revision actually compiles. Change variable names to use "ap" instead of "ouap" everywhere to avoid similar bugs in future.
1.3	03-Sep-1996	mycroft	Define execv() and execve() consistently across emulations. Do path name translation.
1.2	07-Apr-1996	jonathan	branches: 1.2.4; Remove gcc -Wall lint from ultrix emulation.- Mostly adding explicit != comparison to "if (error = copyin/out( ... ))". Fix comment glitch in ultrix_fs.c
1.1	07-Jan-1996	jonathan	Add '/emul/ultrix' pathname processing to Ultrix emulation, and move Ultrix syscalls that require that processing out of ultrix_misc.c to ultrix_pathname.c.
1.2.4.1	10-Dec-1996	mycroft	From trunk: Do execv() and execve() path name translation consistently across emulations.

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.

1.34.6.2	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.
1.34.6.1	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.

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>

1.8	26-Dec-1995	jonathan	Add emulation of ultrix mount(2). Sufficient to NFS-mount filesystems using a NetBSD kernel in an ultrix root filesystem. Move wait emulation to the old (v7) wait syscall number, as that's what the Ultrix ufs_mount binary uses.
1.7	26-Dec-1995	jonathan	Add emulation of Ultrix select: before calling native sys_select(), limit the number of FDs to select on to the maximum supported by NetBSD -- which is as many FDs as the emul_ultrix process can have open, anyway. Add emulation of Ultrix getmnt(2) in ultrix_fs.c Add partial emulation of Ultrix tty ioctl()s in ultrix_ioctl.c, derived from compat/sunos/sunos_ioctl.c. Ultrix libc's ``isatty()'' now works in compat_emul processes.

1.13	26-Dec-1995	jonathan	Add emulation of ultrix mount(2). Sufficient to NFS-mount filesystems using a NetBSD kernel in an ultrix root filesystem. Move wait emulation to the old (v7) wait syscall number, as that's what the Ultrix ufs_mount binary uses.
1.12	26-Dec-1995	jonathan	Add emulation of Ultrix select: before calling native sys_select(), limit the number of FDs to select on to the maximum supported by NetBSD -- which is as many FDs as the emul_ultrix process can have open, anyway. Add emulation of Ultrix getmnt(2) in ultrix_fs.c Add partial emulation of Ultrix tty ioctl()s in ultrix_ioctl.c, derived from compat/sunos/sunos_ioctl.c. Ultrix libc's ``isatty()'' now works in compat_emul processes.

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>
