1.67	20-Dec-2022	msaitoh	Remove sys/compat/common/Makefile.*. These files are not used anymore. Files for compat code are listed in sys/comapt/common/files.common and sys/modules/compat_xxx/Makefile. OK'd by riastradh@ and pgoyette@.
1.66	25-May-2021	pgoyette	PR port-xen/53130 was fixed and closed some time ago, so now we can belatedly re-enable inclusion of the compat_60 x86 microcode code in the loadable module. (It was already being included in the built-in version of the module.)
1.65	27-Jan-2019	pgoyette	branches: 1.65.16; 1.65.18; Merge the [pgoyette-compat] branch
1.64	05-Jun-2018	christos	branches: 1.64.2; use the standard rules, instead of rolling our own.
1.63	20-Dec-2017	maya	branches: 1.63.2; Pass LDFLAGS to ld. Without this, mips64-ld thinks we want to link our n64 objects with the default ABI, n32.
1.62	16-Dec-2017	maxv	compat_util.c must be compiled by default in the kernel. It is needed by generic non-compat code, so it must not depend on anything (libcompat or whatever option we choose to associate it to).
1.61	04-Aug-2017	maxv	typos
1.60	05-Nov-2016	pgoyette	Move if_43.c back into the shared Makefile.sysio where it really belongs. Update the code to invoke the two routines compat_cvtcmd() and compat_ifioctl() through indirect pointers. Initialize those pointers in sys/net/if.c and update them in the compat module's initialization code. Addresses the issue pointed out in PR kern/51598
1.59	03-Nov-2016	pgoyette	Move if_43.c out of Makefile.sysio and into the main Makefile. The former location gets included in both libcompat and the compat module, leading to redefined symbols when the module is loaded. By moving it to the main Makefile, it gets included only in libcompat. XXX This still isn't an ideal solution, but it will suffice until XXX PR kern/51598 is addressed.
1.58	03-Nov-2016	riastradh	Reorganize SRCS lists for libcompat, compat.kmod, sysv_ipc.kmod. - Share lists between the libcompat and module makefiles. - Include some omitted entries in compat.kmod: . if_43.c . kern_sa_60.c . kern_time_30.c . rndpseudo_50.c . rtsock_14.c . rtsock_50.c . rtsock_70.c . uipc_syscalls_40.c . uipc_syscalls_50.c - Exclude a (harmless) spurious entry in sysv_ipc.kmod on LP64 systems: . kern_ipc_10.c Should fix broken ifconfig on modular current kernels. ok pgoyette
1.57	21-Sep-2016	roy	Add ifam_pid and ifam_addrflags to ifa_msghdr. Re-version RTM_NEWADDR, RTM_DELADDR, RTM_CHGADDR and NET_RT_IFLIST. Add compat code for old version.
1.56	06-Apr-2016	roy	branches: 1.56.2; Add sc_pid to sockcred so that SOCK_DGRAM and LOCAL_CREDS socket option can learn the process id of the AF_LOCAL sender. Add compat glue for old structure.
1.55	22-Mar-2016	mrg	remove a bunch of "@echo done" from the tail of rules. these messages were vaguely useful back when we didn't run make -j, but now you end up with a single line "done" every so often, with no idea what it is for. very few other targets claim they're done so just remove these.
1.54	07-Sep-2015	uebayasi	Order library object build.
1.53	07-Sep-2015	uebayasi	Sprinkle more done messages.
1.52	04-Apr-2014	njoly	branches: 1.52.6; Move a few compat 50 syscalls, not applicable to rump kernels, out of kern_time_50.c to a new source module.
1.51	29-Mar-2013	christos	branches: 1.51.4; compat glue for new lwp_park()
1.50	19-Oct-2012	apb	Add COMPAT_60 versions of the TIOCPTMGET and TIOCPTSNAME ioctls.
1.49	19-Feb-2012	matt	branches: 1.49.2; Add compat_60 stub for the SA syscall (all which just call sys_nosys).
1.48	19-Dec-2011	apb	Add COMPAT_50 and COMPAT_NETBSD32 compatibility code for rnd(4) ioctl commands. Tested with "rndctl -ls" using an old 32-bit version of rndctl(8) (built for NetBSD-5.99.56/i386) and a new 64-bit kernel (NetBSD-5.99.59/amd64).
1.47	11-Aug-2011	jmcneill	branches: 1.47.2; 1.47.6; add libcompat.o/.po targets for COMPAT_AS=obj
1.46	17-Jan-2011	pooka	Put async i/o compat routines in a separate source module from the ones related to clock and process management.
1.45	19-Jan-2009	christos	branches: 1.45.6; 1.45.8; Provide compatibility for pre-christos-time_t sysv sysctls.
1.44	11-Jan-2009	christos	merge christos-time_t
1.43	14-Nov-2008	ad	- Move some more compat code into sys/compat. - Split 4.3BSD ifioctl stuff into its own file. - Remove some ifdefs that include small fragments of vfs compat code which are difficult to relocate elsewhere.
1.42	24-Feb-2008	martin	branches: 1.42.2; 1.42.6; 1.42.12; 1.42.14; Remove compat code for posix_fadvise
1.41	27-Jan-2008	martin	branches: 1.41.2; 1.41.6; Implement new version of posix_fadvise as a stub callinig the real worker function, and compatibility stub doing the same with old argument sturcture.
1.40	12-Dec-2007	dsl	compat_file.[ch] are no longer used
1.39	29-May-2007	christos	branches: 1.39.8; 1.39.14; 1.39.16; 1.39.18; 1.39.20; 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.
1.38	10-Mar-2007	dsl	branches: 1.38.2; 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.
1.37	26-Jun-2006	mrg	branches: 1.37.10; 1.37.14; 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.
1.36	11-Dec-2005	christos	branches: 1.36.4; 1.36.8; 1.36.16; merge ktrace-lwp.
1.35	19-Aug-2005	christos	64 bit inode changes.
1.34	26-Feb-2005	perry	branches: 1.34.4; nuke trailing whitespace
1.33	21-Apr-2004	christos	branches: 1.33.4; 1.33.6; Replace the statfs() family of system calls with statvfs(). Retain binary compatibility.
1.32	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.
1.31	08-Dec-2002	manu	branches: 1.31.6; Introduce BSD system calls with alternate patch checking (in /emul) in compat/common, so that they can be shared by several emulations, and use them for Darwin. This removes the ugly dependance on FreeBSD freebsd_file.c for COMPAT_DARWIN
1.30	02-Nov-2002	perry	set LLIBS= so we don't try to check the lint lib against llib-lc.ln
1.29	18-Jun-2002	wrstuden	Updated version of cscope/mkid support. Check libkern and compat lib for source files. Also include header files in mkid run.
1.28	29-Apr-2002	mrg	branches: 1.28.2; 1.28.4; 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.
1.27	12-Dec-2001	tv	MKfoo=no -> NOfoo
1.26	14-Nov-2001	tv	Preload <bsd.own.mk> before .undef DESTDIR.
1.25	14-Nov-2001	tv	Undefine DESTDIR; we don't want the special DESTDIR <bsd.lib.mk> handling for kernel libraries. XXX this build method should be replaced by something more sane
1.24	25-Aug-1999	thorpej	branches: 1.24.14; 1.24.16; Add compatibility calls for the 1.4 System V IPC *ctl() calls, and update the 1.0 compat calls.
1.23	07-May-1999	drochner	Build libraries for kernel/standalone code from within their compilation directories and use .PATH to lookup the source files. (Formerly, the libs were built from the source dirs, with MAKEOBJDIR set to the compilation directory.) This solves 2 problems: -"mkdep" and "make" are now consistent about the file lookup, this fixes bad interactions with amd reported in PR bin/7374 (Arne Juul) and lossage reported by Andrew Gillham ("obj" dirs and relative paths still don't work well together) -kernel compile trees can be moved around without forcing a new "make depend" - fixing PR kern/4021 by Martin Husemann
1.22	13-Feb-1999	lukem	branches: 1.22.4; convert from NOxxx= to MKxxx=no. include <bsd.own.mk> if testing a MKxxx variable.
1.21	28-Apr-1998	kleink	Make adding new source files easier and enhance readability by ordering SRCS items by (Net)BSD version first, then alphabetically.
1.20	25-Nov-1997	kleink	In XPG4.2, the ss_size member of type stack_t (struct sigaltstack) is specified to be of type size_t; since this imposes an interface change on the Alpha (sizeof(int) != sizeof(size_t)), allocate a new system call number and make the previous version a compatibility system call.
1.19	16-Oct-1997	christos	PR/4269: msync is missing MS_*
1.18	10-Oct-1997	fvdl	Add getdirentries backward compat syscall. Provide common function to signal cookie overflow during emulated getdents and friends.
1.17	12-Jun-1997	mrg	branches: 1.17.4; bring mrg-vm-swap2 onto mainline.
1.16	31-May-1997	cjs	Back out BUILDDIR and NOINSTALL changes.
1.15	30-May-1997	cjs	branches: 1.15.2; Use new NOINSTALL option for libraries that are used only during the build of a program, and not installed into the final system.
1.14	07-May-1997	mycroft	Use libinstall::, not install:, to prevent instaling LIB.
1.13	22-Oct-1996	explorer	branches: 1.13.8; Spelling error
1.12	09-Aug-1996	mrg	Change reboot(2) to take two arguments: bootopt like normal and also a boot string for firmware that can do this, such as the SPARC and the sun3 models. It is currently silently ignored on all other hardware now, however. The MD function "boot()" has been changed to also take a char *.
1.11	08-Aug-1996	mycroft	Run the child make in the source directory, so that nothing here needs to be changed when the compile directory is outside the source tree.
1.10	30-Jun-1996	christos	Fix mysterious dissappearance of the .PATH directive.
1.9	23-Jun-1996	mycroft	Remove the old (broken) setre[ug]id() emulation.
1.8	18-May-1996	christos	branches: 1.8.4; - Moving cpu_exec_aout_prep_oldzmagic -> exec_aout_prep_oldzmagic. This is used by the i386, hp300 and mac68k ports. - Added exec_aout_prep_oldomagic, and exec_aout_prep_oldnmagic These are just copies of the respective prep functions from kern_exec.c with text address starting at 0. Maybe a better fix is to pass the starting address as a third argument so we don't duplicate code, but this could be the next pass since the functions are used in many places. These functions are used for BSDI binaries.
1.7	05-Feb-1996	christos	Extracted vm compat functions from vm and added them here where they belong.
1.6	02-Feb-1996	mycroft	Simplify, and add support for passing CPPFLAGS.
1.5	02-Feb-1996	christos	Renamed compat_tty.c to tty_43.c and updated with the newest copy from kern/tty_compat.c
1.4	20-Oct-1995	cgd	set, don't add to, CFLAGS from COMPATCFLAGS
1.3	28-Jun-1995	cgd	light cleanup, adjustments for the Alpha
1.2	26-Jun-1995	christos	Add the ability to override COMPATREL and COMPATDST similar to libkern
1.1	24-Jun-1995	christos	- Extracted all compat routines from the kern directory and moved here. - Created compat_util.c and compat_util.h to be used by the compatibility modules, so they don't duplicate the same code. - Added prototypes to the stackgap allocation routines.
1.8.4.2	10-Dec-1996	mycroft	Oops; put back .PATH.
1.8.4.1	10-Dec-1996	mycroft	From trunk: Implement setre[ug]id() for real.
1.13.8.1	04-May-1997	mrg	add vm_swap_12.c here.

1.12	23-Jan-1997	cgd	clean up substantially. Transform clean, depend, cleandir targets from :: to :, so they can be used e.g. with <bsd.prog.mk>. Standardize variable names used to configure kernel libraries. Variables used by these Makefile.inc's are: S must be set to the top of the 'sys' tree. ${LIB}DST may be set to the location of the directory where library objects are to be built. Defaults to ${.OBJDIR}/lib/${lib}. ${LIB}_AS may be set to 'obj' to build a object from the library's object files. (Otherwise, a library will be built.) Defaults to 'library'. ${LIB}MISCMAKEFLAGS Miscellaneous flags to be passed to the library's Makefile when building. See library's Makefile for more details about supported flags and their default values. (where LIB is COMPAT, and lib is compat, in this case.)

1.13	27-Jan-2020	pgoyette	Split the module glue out from the rest of opencrypto/ocryptodev to make rump happy. Rump doesn't have compat modules (the compat code is included in the relevant librump*.so), so there's no module compat_50 listed in link_set_modules, and thus ocryptodev's MODULE(...) can't "require" it. This fixes the problem of "built-in module compat_50 not found" when starting up rump_allserver (or rump_server with -l rumpdev_opencrypto). XXX This does not resolve the long-standing "crypto: unable to XXX register devsw, error 17" message noted at line 78 of XXX sys/rump/dev/lib/libopencrypto/opencrypto_component.c
1.12	17-May-2019	msaitoh	branches: 1.12.4; 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()

1.7	05-Nov-2016	pgoyette	branches: 1.7.2; 1.7.16; 1.7.18; Move if_43.c back into the shared Makefile.sysio where it really belongs. Update the code to invoke the two routines compat_cvtcmd() and compat_ifioctl() through indirect pointers. Initialize those pointers in sys/net/if.c and update them in the compat module's initialization code. Addresses the issue pointed out in PR kern/51598
1.6	03-Nov-2016	pgoyette	branches: 1.6.2; Move if_43.c out of Makefile.sysio and into the main Makefile. The former location gets included in both libcompat and the compat module, leading to redefined symbols when the module is loaded. By moving it to the main Makefile, it gets included only in libcompat. XXX This still isn't an ideal solution, but it will suffice until XXX PR kern/51598 is addressed.
1.5	03-Nov-2016	pgoyette	Hmmm, if we omit if_43.c from the SRCS list, then we break the i386 build for one of the XEN kernels. Adding it back to the list. At least the build will be successful. XXX This is probably not the end of this saga, as we still have the XXX redefined-symbol issue when loading the compat module on amd64. XXX But for now, a working build for the vast majority of users XXX (including our automated test suites) is more important than a XXX successfully-loadable compat module.
1.4	03-Nov-2016	pgoyette	Really comment out if_43.c this time. (I need sleep and/or caffeine.)
1.3	03-Nov-2016	pgoyette	Use proper characgter to introduce comments!
1.2	03-Nov-2016	pgoyette	if_43.o gets included from libcompat automatically, due to two calls to compat_cvtcmd() in if.c. Ideally, if.c would be modified to have a pointer to a no-op compat_cvtcmd() and that pointer would get replaced by compat_modcmd(MODULE_CMD_INIT, ...) code. But for now, just don't include it in the compat module at all.
1.1	03-Nov-2016	riastradh	Reorganize SRCS lists for libcompat, compat.kmod, sysv_ipc.kmod. - Share lists between the libcompat and module makefiles. - Include some omitted entries in compat.kmod: . if_43.c . kern_sa_60.c . kern_time_30.c . rndpseudo_50.c . rtsock_14.c . rtsock_50.c . rtsock_70.c . uipc_syscalls_40.c . uipc_syscalls_50.c - Exclude a (harmless) spurious entry in sysv_ipc.kmod on LP64 systems: . kern_ipc_10.c Should fix broken ifconfig on modular current kernels. ok pgoyette

1.7.18.22	19-Sep-2018	pgoyette	Update for new vnd_50.c source file. Not really necessary to update this, since we're no longer building the "monolithic" compat module. But let's maintain it correctly, at least until we delete the file.

1.1.2.10	18-Mar-2018	pgoyette	Merge changes from HEAD into ccd_60.c For all of the individual xxx_60_{init,fini} routines, don't force them to artificially return a status; just make them void. This simplifies the compat_60_{init,fini} handling of errors that remain.
1.1.2.9	18-Mar-2018	pgoyette	Import compat_60 changes for dev/ccd
1.1.2.8	18-Mar-2018	pgoyette	Initial pass at getting the tty stuff properly modularized. Subject to review and revision.
1.1.2.7	18-Mar-2018	pgoyette	Clean-up for kern_cpu_60 code. Also, although not strictly necessary, include the kern_sa_60 stuff in the compat_60 module, for completeness. Still need to deal with some tty code and the ccd driver to finish off the compat_60 module.
1.1.2.6	18-Mar-2018	pgoyette	Move closer to a complete compat_60 module. All that remains is some tty stuff and some ccd ioctl()s.
1.1.2.5	17-Mar-2018	pgoyette	Back out changes on the branch related to kernel microcode compat. Christos didn't like the way it was done, so waiting for a better approach/implementation.

So, simplify the required-modules lists to require only the next-highest version's module. This will also make it easier to add new compat_xx modules for future release versions.

1.4	17-May-2019	msaitoh	branches: 1.4.2; 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()

Stop overloading VTEXT for this purpose (VTEXT also has another meaning). - Rename vn_marktext() to vn_markexec(), and use it when executable mappings of a vnode are established. - In places where we want to set VTEXT, set it in v_flag directly, rather than making a function call to do this (it no longer makes sense to use a function call, since we no longer overload VTEXT with VEXECMAP's meaning). VEXECMAP suggested by Chuq Silvers.

Maybe a better fix is to pass the starting address as a third argument so we don't duplicate code, but this could be the next pass since the functions are used in many places. These functions are used for BSDI binaries.

1.22	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.

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.

XXX Whatever was I thinking when I put those conditionals in? And wouldn't it be a wonderful thing to have some atf regression tests to actually catch errors in the compat{,_sysv} modules? :)
1.21	10-May-2015	pgoyette	Split the SYSV* compat code out into a separate compat_sysv module. For monolithic kernels, both modules will be compiled as "built-ins", while modular environments will be able to load the SYSVSEM, SYSVSHM, and SYSVMSG code independant from the rest of compat. This is a necessary precursor step to making the "STD" SYSV* code into a separate module. Tested in both monolithic and modular environments with no errors seen.

1.5	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()

1.1.42.24	11-Jan-2019	pgoyette	Rework the various sysctl-related routines to call the correct code for each version. While here, extract the 5.0 specific code instead of including in the main rtsock.c code. Also, clean up all the sysctl-related routines to prevent building more than one copy, no matter how many places rtsock.c gets #include'd into!
1.1.42.23	12-Oct-2018	pgoyette	Use a MP-safe hook for the rnd_ioctl compat_50 calls.
1.1.42.22	19-Sep-2018	pgoyette	Split out the vnd COMPAT_50 code
1.1.42.21	17-Apr-2018	pgoyette	Finish separating the compat_09 and compat_43 stuff
1.1.42.20	17-Apr-2018	pgoyette	First pass at compat modules for 4.3BSD, NetBSD-0.9, and NetBSD-1.0 XXX Still need to deal with the sysctl stuff and other code shared XXX between 09 and 43
1.1.42.19	16-Apr-2018	pgoyette	Rename if_[45]0_{init,fini} entry points to more appropriate and more consistent uipc_syscalls_[45]0_{init,fini} and remove some multiple declarations.
1.1.42.18	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.
1.1.42.17	31-Mar-2018	pgoyette	create the compat_12 module
1.1.42.16	30-Mar-2018	pgoyette	Add compat_13 module
1.1.42.15	30-Mar-2018	pgoyette	Extract compat_14 stuff into its own module
1.1.42.14	30-Mar-2018	pgoyette	Create and build a compat_16 module
1.1.42.13	30-Mar-2018	pgoyette	Create and build the compat_20 module
1.1.42.12	29-Mar-2018	pgoyette	Split out the usb compat_30 code and add it to the module
1.1.42.11	28-Mar-2018	pgoyette	Split vnd compat_30 code out of the main driver and into the compat_30 module
1.1.42.10	28-Mar-2018	pgoyette	Initial pass at a compat_30 module. Still needs some work for dev/vnd and various dev/usb/*
1.1.42.9	27-Mar-2018	pgoyette	Create a compat_40 module
1.1.42.8	23-Mar-2018	pgoyette	For now, the compat_80 module is empty.
1.1.42.7	19-Mar-2018	pgoyette	Initial pass at a COMPAT_50 module. More to come.
1.1.42.6	18-Mar-2018	pgoyette	Merge changes from HEAD into ccd_60.c For all of the individual xxx_60_{init,fini} routines, don't force them to artificially return a status; just make them void. This simplifies the compat_60_{init,fini} handling of errors that remain.
1.1.42.5	18-Mar-2018	pgoyette	Clean-up for kern_cpu_60 code. Also, although not strictly necessary, include the kern_sa_60 stuff in the compat_60 module, for completeness. Still need to deal with some tty code and the ccd driver to finish off the compat_60 module.
1.1.42.4	18-Mar-2018	pgoyette	Move closer to a complete compat_60 module. All that remains is some tty stuff and some ccd ioctl()s.
1.1.42.3	17-Mar-2018	pgoyette	Make all the compat_xx_{init,fini} routines return an int, whether or not they currently need it.
1.1.42.2	16-Mar-2018	pgoyette	Move closer to getting a compat_60 module - still needs more work
1.1.42.1	16-Mar-2018	pgoyette	Initial pass at setting up the compat_60 module. XXX needs some work to properly handle cpu_ucode stuff. While here, move details of compat_70 init/fini routines into the module itself.

This is an XXX comment block only, NFCI. Modularize the COMPAT_90 code that resulted from the removal of netinet6/nd6 from the kernel. Now, the minimal compat code can be successfully loaded and unloaded along with the rest of the COMPAT_90 code. Allow kernels builds which don't define INET6 to compile compat bits too. Default the build of compat_90 module to include IPv6, as is done for other INET6-sensitive modules (see if_lagg).

1.1.2.1	22-Sep-2018	pgoyette	Split the raidframe compatability code out into separate modules, since the driver is already a module. This avoids having to pass a bunch of function pointers as arguments to raidframe's compat_ioctl().

1.2	16-Jun-2007	dsl	branches: 1.2.2; 1.2.12; 1.2.60; 1.2.66; 1.2.70; 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...
1.1	03-Jun-2007	dsl	branches: 1.1.2; Add a #define that expands to the compat wrapper for sigaltstack1(). Use it for the netbsd32_compat_13.c version of the code.

1.6	26-Mar-2020	pgoyette	When using SYSCTL_SETUP there is no guarantee of the order in which the set-up functions will be called, so it is perfectly acceptable for a compat code's routine to be called ahead of the code in other parts of the kernel. So make sure that the 2nd level sysctl node ``vfs.generic'' exists before trying to add the 3rd level entries. XXX Rather than creating the 2nd level node in two places, we could XXX add the shared ``vfs.generic'' node to sysctl_init_base.c but XXX this is left for another day.
1.5	27-Feb-2020	pgoyette	Ooppss - SYSCTL_SETUP() functions return void.
1.4	27-Feb-2020	pgoyette	Remove explicit calls to the sysctl setup routines, since this is now handled by the module infrastructure.
1.3	06-Dec-2019	maxv	branches: 1.3.2; Fix a bunch of unimportant "Local variable hides global variable" warnings from the LGTM bot.

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.

1.1	17-Apr-2018	pgoyette	branches: 1.1.2; file compat_sysv_50_mod.c was initially added on branch pgoyette-compat.
1.1.2.3	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.
1.1.2.2	15-Oct-2018	pgoyette	Convert the final non-MP-safe "vectored" compat routine to use the MP-safe mechanism.
1.1.2.1	17-Apr-2018	pgoyette	Split the compat_sysv module into several version-specific modules, similar to the compat module.

1.4	03-Dec-2015	pgoyette	branches: 1.4.10; Merge the compat_sysv module into the sysv_ipc module - it should never have been a separate module in the first place (my bad). Adjust dependencies as appropriate.
1.3	13-May-2015	pgoyette	branches: 1.3.2; The compat_sysv module now depends on sysv_ipc module.
1.2	11-May-2015	pgoyette	Fix the #ifdef _MODULE stuff so that the syscall packages and sysctl stuff gets handled properly even in built-in module case. XXX Whatever was I thinking when I put those conditionals in? And wouldn't it be a wonderful thing to have some atf regression tests to actually catch errors in the compat{,_sysv} modules? :)
1.1	10-May-2015	pgoyette	Split the SYSV* compat code out into a separate compat_sysv module. For monolithic kernels, both modules will be compiled as "built-ins", while modular environments will be able to load the SYSVSEM, SYSVSHM, and SYSVMSG code independant from the rest of compat. This is a necessary precursor step to making the "STD" SYSV* code into a separate module. Tested in both monolithic and modular environments with no errors seen.

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.

1.38	08-Dec-2007	dsl	ANSIfy most of the function definitions in sys/compat (but not ndis). All by the magic of sed ...
1.37	13-Jul-2007	dsl	branches: 1.37.6; 1.37.8; 1.37.14; 1.37.16; Put the stackgap code under OPT_SYSTRACE.
1.36	26-Apr-2007	dsl	Pass the emulation root string into namei() from emul_find_interp() so that the ktrace entries for lookups done during exec can have the full filename. This is rather a hack :-)
1.35	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.
1.34	04-Mar-2007	christos	branches: 1.34.2; 1.34.4; Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.
1.33	24-Nov-2006	wiz	branches: 1.33.4; s/existance/existence/, from Zafer.
1.32	23-Jul-2006	ad	branches: 1.32.4; 1.32.6; Use the LWP cached credentials where sane.
1.31	14-May-2006	elad	integrate kauth.
1.30	11-Dec-2005	christos	branches: 1.30.4; 1.30.6; 1.30.8; 1.30.10; 1.30.12; merge ktrace-lwp.
1.29	29-May-2005	christos	branches: 1.29.2; - sprinkle const. - add XXXUNCONST to the emul_find() pbuf argument free'ing. XXX: this needs an api change. - avoid variable shadowing.
1.28	26-Feb-2005	perry	nuke trailing whitespace
1.27	29-Jun-2003	fvdl	branches: 1.27.2; 1.27.10; 1.27.12; Back out the lwp/ktrace changes. They contained a lot of colateral damage, and need to be examined and discussed more.
1.26	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
1.25	29-Nov-2002	jdolecek	add emul_find_interp() function: the function looks for interpreter in alternative emul tree first, and updates interpreter pathname if found there; if not found in alternative emul tree, pathname without the emul prefix is checked, and error returned if the file doesn't exist
1.24	23-Sep-2002	simonb	Remove a meaningless type qualifier on a cast.
1.23	17-Mar-2002	christos	panic if more space than stackgaplen is requested. Maybe I should remove the size option completely.
1.22	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.
1.21	13-Nov-2001	lukem	add RCSIDs (including regeneration of files as appropriate)
1.20	02-Feb-2001	jdolecek	branches: 1.20.2; 1.20.4; emul_find(): actually, the emulation root vnode dance has to be done for CHECK_ALT_SYMLINK() same way as for CHECK_ALT_EXISTS() This fixes lossage reported on current-users and kern/12019 by Ross Harvey.
1.19	22-Jan-2001	jdolecek	Introduce CHECK_ALT_SYMLINK() - this checks for alternative location without following links, hence is usable for checking of presence of a symlink. Also slighly cleanup EXISTS and CREAT cases - use symbolic constants instead of 0/1. This is needed for emulation of readlink(2), lchown(2) and similar. Addresses kern/11757.
1.18	20-Nov-2000	jdolecek	make const the struct emul * pointers passed/used in stackgap_init(), stackgap_alloc()
1.17	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.
1.16	29-Aug-2000	sommerfeld	Emulation stackgap sanity checks, based partly on fixes from FreeBSD-SA00:42. Change stackgap_alloc to bounds-check the allocation vs. the stack gap, returning NULL if there isn't room for the allocation. Change emul_find() to check for a NULL return from stackgap_alloc() and convert that into ENAMETOOLONG. Reorder various emulation syscalls so that all _CHECK_ALT_{EXIST,CREAT} calls (which turn into emul_find() under the covers come after* small, fixed-size stackgap_alloc() calls. Clean up ibcs2 {get,set}groups.
1.15	26-Jun-2000	mrg	remove redundant vm includes.
1.14	27-Apr-1999	christos	branches: 1.14.2; 1.14.12; From cgd again: pbuf == path on failure.
1.13	27-Apr-1999	christos	Make the usage consistant and document it: if the path was given in a user buffer, return the new path in a user buffer. if the path was given in a kernel buffer, allocate a new kernel buffer to return the new path; the caller is responsible for freeing the buffer if we fail always set the new path to NULL. This usage broke when I adde the /../ shortcut. Noted by cgd.
1.12	24-Apr-1999	cgd	implement a simple function, emul_flags_translate() to do table-based flags translation.
1.11	14-Feb-1999	christos	branches: 1.11.2; 1.11.4; 1.11.6; Provide a way for compat programs to specify files in the normal tree. We do this using a trick similar to mach's /../; if a path is given as /..<absolute-path-name>, then we return <absolute-path-name>
1.10	09-Feb-1999	christos	char * and char ** -> const char * and const char **
1.9	03-Oct-1998	fvdl	Assign to TNF completely.
1.8	05-Sep-1998	christos	Assign copyright to TNF.
1.7	10-Oct-1997	fvdl	Add getdirentries backward compat syscall. Provide common function to signal cookie overflow during emulated getdents and friends.
1.6	25-Oct-1996	cgd	branches: 1.6.10; make the namei struct members ni_dirp and ni_next, and the componentname struct member cn_nameptr 'const', since they should never be used to modify the path name. (Only the pathname buffer, cn_pnbuf, should be modified.) Propagate the const poisoning to code that uses the namei and componentname structs.
1.5	12-Oct-1996	thorpej	Don't inline stackgap_init() and stackgap_alloc(). Doing so generates an include file dependency graph that's much more complicated than it needs to be, and wastes space in the kernel.
1.4	14-Mar-1996	christos	Fix compiler warnings
1.3	22-Oct-1995	mycroft	Make sure we free the pathname buffer in all error cases.
1.2	26-Jun-1995	christos	branches: 1.2.2; Fix PR1160... (bug with the new compat_util prefix)
1.1	24-Jun-1995	christos	- Extracted all compat routines from the kern directory and moved here. - Created compat_util.c and compat_util.h to be used by the compatibility modules, so they don't duplicate the same code. - Added prototypes to the stackgap allocation routines.
1.2.2.1	22-Oct-1995	mycroft	Make sure we free the pathname buffer in all error cases.
1.6.10.1	14-Oct-1997	thorpej	Update marc-pcmcia branch from trunk.
1.11.6.1	30-Nov-1999	itojun	bring in latest KAME (as of 19991130, KAME/NetBSD141) into kame branch just for reference purposes. This commit includes 1.4 -> 1.4.1 sync for kame branch. The branch does not compile at all (due to the lack of ALTQ and some other source code). Please do not try to modify the branch, this is just for referenre purposes. synchronization to latest KAME will take place on HEAD branch soon.

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.

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
1.20	28-Apr-2008	martin	branches: 1.20.6; 1.20.8; 1.20.14; Remove clause 3 and 4 from TNF licenses
1.19	20-Jan-2008	dsl	branches: 1.19.6; 1.19.8; 1.19.10; Remove stackgap functions externs.
1.18	22-Apr-2007	dsl	branches: 1.18.8; 1.18.14; 1.18.20; 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.
1.17	04-Mar-2007	christos	branches: 1.17.2; 1.17.4; Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.
1.16	11-Dec-2005	christos	branches: 1.16.26; merge ktrace-lwp.
1.15	29-May-2005	christos	branches: 1.15.2; - sprinkle const. - add XXXUNCONST to the emul_find() pbuf argument free'ing. XXX: this needs an api change. - avoid variable shadowing.
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	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
1.12	29-Nov-2002	jdolecek	add emul_find_interp() function: the function looks for interpreter in alternative emul tree first, and updates interpreter pathname if found there; if not found in alternative emul tree, pathname without the emul prefix is checked, and error returned if the file doesn't exist
1.11	29-Nov-2002	jdolecek	de-__P()
1.10	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.
1.9	22-Jan-2001	jdolecek	branches: 1.9.2; 1.9.4; Introduce CHECK_ALT_SYMLINK() - this checks for alternative location without following links, hence is usable for checking of presence of a symlink. Also slighly cleanup EXISTS and CREAT cases - use symbolic constants instead of 0/1. This is needed for emulation of readlink(2), lchown(2) and similar. Addresses kern/11757.
1.8	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
1.7	20-Nov-2000	jdolecek	make const the struct emul * pointers passed/used in stackgap_init(), stackgap_alloc()
1.6	24-Apr-1999	cgd	branches: 1.6.2; implement a simple function, emul_flags_translate() to do table-based flags translation.
1.5	09-Feb-1999	christos	branches: 1.5.2; 1.5.4; 1.5.6; char * and char ** -> const char * and const char **
1.4	05-Sep-1998	christos	Assign copyright to TNF.
1.3	10-Oct-1997	fvdl	Add getdirentries backward compat syscall. Provide common function to signal cookie overflow during emulated getdents and friends.
1.2	12-Oct-1996	thorpej	branches: 1.2.10; Don't inline stackgap_init() and stackgap_alloc(). Doing so generates an include file dependency graph that's much more complicated than it needs to be, and wastes space in the kernel.
1.1	24-Jun-1995	christos	- Extracted all compat routines from the kern directory and moved here. - Created compat_util.c and compat_util.h to be used by the compatibility modules, so they don't duplicate the same code. - Added prototypes to the stackgap allocation routines.
1.2.10.1	14-Oct-1997	thorpej	Update marc-pcmcia branch from trunk.
1.5.6.1	30-Nov-1999	itojun	bring in latest KAME (as of 19991130, KAME/NetBSD141) into kame branch just for reference purposes. This commit includes 1.4 -> 1.4.1 sync for kame branch. The branch does not compile at all (due to the lack of ALTQ and some other source code). Please do not try to modify the branch, this is just for referenre purposes. synchronization to latest KAME will take place on HEAD branch soon.

1.14.2.1	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.

1.14	20-May-2024	christos	remove dup line
1.13	20-May-2024	christos	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.
1.12	19-May-2024	christos	version dup3
1.11	09-Dec-2023	pgoyette	Modularize the COMPAT_90 code that resulted from the removal of netinet6/nd6 from the kernel. Now, the minimal compat code can be successfully loaded and unloaded along with the rest of the COMPAT_90 code. XXX pullup-10 - hopefully before RC2

1.6	21-Jan-2020	pgoyette	Split the compat_50 module into two, separating the QUOTA-related stuff from the rest of the module. This allows loading of the (main) compat_50 module on kernels that don't include ``options QUOTA''. Welcome to 9.99.40 ! Addresses PR kern/54875
1.5	22-Sep-2019	christos	branches: 1.5.2; 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=
1.4	17-May-2019	msaitoh	branches: 1.4.2; 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()
1.3	15-Apr-2019	pgoyette	Split the COMPAT_50 socket-timeout stuff out of kern/uipc_socket.c and into its own source file, which is now included in the compat_50 module. (Not sure how this got missed during the original [pgoyette-compat] work)
1.2	27-Jan-2019	pgoyette	Merge the [pgoyette-compat] branch

1.1.2.30	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.

1.1.2.19	27-Mar-2018	pgoyette	Create a compat_40 module
1.1.2.18	24-Mar-2018	pgoyette	Separate the compat_50 and compat_80 dispatching code from the main body of raidframe, and place into the appropriate compat modules. Enable building of the compat_80 module.
1.1.2.17	23-Mar-2018	pgoyette	For now, the compat_80 module is empty.
1.1.2.16	21-Mar-2018	pgoyette	Move if_spppsubr compat code into the compat50 module. More prep work for compat80 module (for raidframe)
1.1.2.15	21-Mar-2018	pgoyette	Split the compat_50 code out from the dev/clockctl driver and include it in the compat_50 and compat modules.

1.1.2.10	15-Mar-2018	pgoyette	Resolve conflicts from sync-with-HEAD
1.1.2.9	14-Mar-2018	pgoyette	Tag files with their specific compat version required. This way the files only get included if needed, allowing for subsequent loading of COMPAT_xx modules for older-than-built-in code.
1.1.2.8	14-Mar-2018	pgoyette	Make do_openat()'s handling of path=NULL modular
1.1.2.7	13-Mar-2018	pgoyette	Move the swapstats compat code into the compat_netbsd module. Without this, a kernel configured without COMPAT_13 and/or COMPAT_50 could not execute the compat swapstats code, even if the compat_netbsd module had been loaded.
1.1.2.6	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.
1.1.2.5	09-Mar-2018	pgoyette	More on renaming the new module
1.1.2.4	09-Mar-2018	pgoyette	Split the sysv_ipc module into two pieces: one for contemporary SYSV* functionality, and one for compatability with previous NetBSD versions. No need to pull in all of compat just to have a sysv_ipc module.
1.1.2.3	06-Mar-2018	pgoyette	Move necessary routines out of compat_util.c and into exec_elf.c Once again, compat_util.c is only for modules, so move it back into compat/common/files.common and out of kern/files.kern
1.1.2.2	06-Mar-2018	pgoyette	compat_util.c is included in all kernels, so does not need to be listed here.
1.1.2.1	06-Mar-2018	pgoyette	Add a files.common to list all the compat source files.

This is an XXX comment block only, NFCI. Modularize the COMPAT_90 code that resulted from the removal of netinet6/nd6 from the kernel. Now, the minimal compat code can be successfully loaded and unloaded along with the rest of the COMPAT_90 code. Allow kernels builds which don't define INET6 to compile compat bits too. Default the build of compat_90 module to include IPv6, as is done for other INET6-sensitive modules (see if_lagg).

1.7	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.
1.6	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 !

Naming: Should the names of the hooks be: <category>_<version>_<function>_hook_t or: <category>_<function>_<version>_hook_t We should make those consistent.

1.1	30-Mar-2018	pgoyette	branches: 1.1.2; file ieee80211_20.c was initially added on branch pgoyette-compat.
1.1.2.3	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.

1.27	30-Mar-2023	riastradh	atalk(4): Omit spurious satosat. The input is already a struct sockaddr_at pointer.
1.26	28-Sep-2022	msaitoh	branches: 1.26.4; Simplify sys/compat/sys/sockio.h. No functional change intended. - Move some definitions from sys/compat/sockio.h to compat/net/if.h. struct oif_data in sockio.h and if_data50 are the same, so remove oif_data. Do the same thing to oifdatareq, too. - u_quad_t -> uint64_t. No functional change.
1.25	12-Jun-2020	roy	Remove in-kernel handling of Router Advertisements This is much better handled by a user-land tool. Proposed on tech-net here: https://mail-index.netbsd.org/tech-net/2020/04/22/msg007766.html Note that the ioctl SIOCGIFINFO_IN6 no longer sets flags. That now needs to be done using the pre-existing SIOCSIFINFO_FLAGS ioctl. Compat is fully provided where it makes sense, but trying to turn on RA handling will obviously throw an error as it no longer exists. Note that if you use IPv6 temporary addresses, this now needs to be turned on in dhcpcd.conf(5) rather than in sysctl.conf(5).
1.24	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.

1.23	23-Sep-2019	maxv	Remove unused assignment. Found by the lgtm bot.
1.22	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()
1.21	16-Apr-2019	msaitoh	Rename ifreqo2n() and ifreqo2n() to IFREQO2N_43() and IFREQN2O_43(): - ifreqo2n() and ifreqn2o() are for COMPAT_43, so add _43 to the name. - Uppercase to make it clear those are macros.
1.20	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.

1.13	05-Nov-2016	pgoyette	Move if_43.c back into the shared Makefile.sysio where it really belongs. Update the code to invoke the two routines compat_cvtcmd() and compat_ifioctl() through indirect pointers. Initialize those pointers in sys/net/if.c and update them in the compat module's initialization code. Addresses the issue pointed out in PR kern/51598

1.10	12-May-2015	christos	rump is compiled with COMPAT_OSOCK not COMPAT_OIFREQ and the code in if.c is not handling this case properly. Make this work by checking again if we need to convert struct ifreq here, and if we do, we do it ourselves.

1.7	01-Jul-2014	rtr	branches: 1.7.2; fix parameter types in pr_ioctl, called xx_control() functions and remove abuse of pointer to struct mbuf type. param2 changed to u_long type and uses parameter name 'cmd' (ioctl command) param3 changed to void * type and uses parameter name 'data' param4 changed to struct ifnet * and uses parameter name 'ifp' param5 has been removed (formerly struct lwp ) and uses of 'l' have been replaced with curlwp from curproc(9). callers have had (now unnecessary) casts to struct mbuf removed, called code has had (now unnecessary) casts to u_long, void * and struct ifnet * respectively removed. reviewed by rmind@
1.6	22-Jun-2014	rtr	* split PRU_CONTROL functionality out of xxx_userreq() switches and place into separate xxx_ioctl() functions. * place KASSERT(req != PRU_CONTROL) inside xxx_userreq() as it is now inappropriate for req = PRU_CONTROL in xxx_userreq(). * replace calls to pr_generic() with req = PRU_CONTROL with pr_ioctl(). * remove & fixup references to PRU_CONTROL xxx_userreq() function comments. * fix various comments references for xxx_userreq() that mentioned PRU_CONTROL as xxx_userreq() no longer handles the request. a further change will follow to fix parameter and naming inconsistencies retained from original code. Reviewed by rmind@
1.5	18-May-2014	rmind	Add struct pr_usrreqs with a pr_generic function and prepare for the dismantling of pr_usrreq in the protocols; no functional change intended. PRU_ATTACH/PRU_DETACH changes will follow soon. Bump for struct protosw. Welcome to 6.99.62!

1.14.4.2	08-Apr-2020	martin	Merge changes from current as of 20200406
1.14.4.1	10-Jun-2019	christos	Sync with HEAD
1.14.2.15	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.
1.14.2.14	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 {}.
1.14.2.13	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).
1.14.2.12	14-Jan-2019	pgoyette	Create a variant of the HOOK macros that handles hook routines of type void, and use them where appropriate.
1.14.2.11	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.
1.14.2.10	15-Oct-2018	pgoyette	Convert a couple more hooks to the MP-safe mechanism. While here, clean up some headers and remove any that are now empty.
1.14.2.9	03-Oct-2018	pgoyette	Don't define if_43_{init,fini}() in multiple .h files.
1.14.2.8	03-Oct-2018	pgoyette	Make if_43_{init,fini} return an int, for consistency with all the related *_{init,fini} routines.
1.14.2.7	30-Sep-2018	pgoyette	Ssync with HEAD
1.14.2.6	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).
1.14.2.5	21-Sep-2018	pgoyette	Clean-up some pre-existing function-pointer code (related to if_43) to use the new MP-safe mechanism.
1.14.2.4	18-Sep-2018	pgoyette	The COMPAT_HOOK macros were renamed to MODULE_HOOK, adjust all callers
1.14.2.3	18-Sep-2018	pgoyette	Split the COMPAT_CALL_HOOK to separate the declaration from the implementation. Some hooks are called from multiple source files, and the old method resulted in duplicate implementations. Implement MP-safe hooks for the usb_subr_30 code. Pass the helper functions as arguments to the compat code so it does not have to determine if the kernel contains usb code.
1.14.2.2	17-Sep-2018	pgoyette	Adapt (most of) the indirect function pointers to the new MP-safe mechanism. Still remaining are the compat_netbsd32 stuff, and some usb subroutines.
1.14.2.1	30-Mar-2018	pgoyette	Create and build the compat_20 module
1.26.4.1	31-Jul-2023	martin	Pull up following revision(s) (requested by riastradh in ticket #278): sys/netatalk/ddp_output.c: revision 1.22 sys/compat/common/if_43.c: revision 1.27 sys/netatalk/ddp_input.c: revision 1.34 sys/netatalk/at_control.c: revision 1.43 atalk(4): Don't abuse queue(9) internals. atalk(4): Omit spurious satosat.

1.2	27-Jan-2019	pgoyette	Merge the [pgoyette-compat] branch
1.1	05-Nov-2016	pgoyette	branches: 1.1.2; 1.1.4; 1.1.18; 1.1.20; 1.1.22; Move if_43.c back into the shared Makefile.sysio where it really belongs. Update the code to invoke the two routines compat_cvtcmd() and compat_ifioctl() through indirect pointers.

1.5	03-Aug-2022	riastradh	sys/compat/common/if_media_80.c: Add kernel rcsid.
1.4	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.
1.3	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 !
1.2	26-Sep-2019	christos	fix sign-compare issues.
1.1	17-May-2019	msaitoh	branches: 1.1.2; 1.1.4; 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()

1.1.2.6	31-Mar-2018	pgoyette	Re-enable inclusion of CPU_UCODE for i386/amd64. Even though it won't build correctly on XEN (won't use the XEN ABI), it works fine on real hardware.
1.1.2.5	18-Mar-2018	pgoyette	Merge changes from HEAD into ccd_60.c For all of the individual xxx_60_{init,fini} routines, don't force them to artificially return a status; just make them void. This simplifies the compat_60_{init,fini} handling of errors that remain.
1.1.2.4	18-Mar-2018	pgoyette	Clean-up for kern_cpu_60 code. Also, although not strictly necessary, include the kern_sa_60 stuff in the compat_60 module, for completeness. Still need to deal with some tty code and the ccd driver to finish off the compat_60 module.

1.23	27-Jan-2019	pgoyette	Merge the [pgoyette-compat] branch
1.22	04-Nov-2009	rmind	branches: 1.22.62; 1.22.64; 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 ?).
1.21	20-Dec-2007	dsl	branches: 1.21.10; 1.21.12; 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.
1.20	19-Oct-2007	ad	branches: 1.20.4; 1.20.8; machine/{bus,cpu,intr}.h -> sys/{bus,cpu,intr}.h
1.19	07-May-2007	dsl	branches: 1.19.6; 1.19.8; 1.19.12; 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.
1.18	04-Mar-2007	christos	branches: 1.18.2; 1.18.4; Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.
1.17	09-Feb-2007	ad	branches: 1.17.2; Merge newlock2 to head.
1.16	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.
1.15	16-Nov-2006	christos	__unused removal on arguments; approved by core.

1.9	25-Sep-2002	thorpej	Don't include <sys/map.h>.
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	13-Nov-2001	lukem	add RCSIDs (including regeneration of files as appropriate)

1.1	24-Jun-1995	christos	- Extracted all compat routines from the kern directory and moved here. - Created compat_util.c and compat_util.h to be used by the compatibility modules, so they don't duplicate the same code. - Added prototypes to the stackgap allocation routines.

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.

1.22	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.
1.21	27-Jan-2019	pgoyette	branches: 1.21.4; Merge the [pgoyette-compat] branch

1.14	04-Dec-2003	atatat	branches: 1.14.16; 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.

1.11	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.

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.

1.20.12.2	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.
1.20.12.1	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.

1.40	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.
1.39	30-Jan-2020	christos	- make sure size is not used uninitialized - limit size range - fix type botch for "size" from maxv@
1.38	02-Jan-2020	thorpej	branches: 1.38.2; - 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.
1.37	27-Jan-2019	pgoyette	branches: 1.37.4; Merge the [pgoyette-compat] branch
1.36	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!)
1.35	24-Mar-2014	christos	branches: 1.35.22; 1.35.28; 1.35.30; use cpu_getmodel() to get the model name

1.33	24-Apr-2008	ad	branches: 1.33.2; 1.33.4; 1.33.10; 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.
1.32	08-Jan-2008	elad	branches: 1.32.6; 1.32.8; 1.32.10; Make compat_43_sys_sethostid() use old_sysctl(), allowing for the removal of a kauth(9) call. okay christos@.

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.

1.19	04-Dec-2003	atatat	branches: 1.19.8; 1.19.10; 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.
1.18	19-Nov-2003	christos	Don't include malloc.h if you are not going to use it.
1.17	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.
1.16	29-Jun-2003	fvdl	branches: 1.16.2; Back out the lwp/ktrace changes. They contained a lot of colateral damage, and need to be examined and discussed more.
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
1.14	18-Jan-2003	thorpej	Merge the nathanw_sa branch.
1.13	13-Nov-2001	lukem	add RCSIDs (including regeneration of files as appropriate)

1.10	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.
1.9	24-Mar-1999	mrg	branches: 1.9.8; completely remove Mach VM support. all that is left is the all the header files as UVM still uses (most of) these.
1.8	10-Feb-1998	mrg	- add defopt's for UVM, UVMHIST and PMAP_NEW. - remove unnecessary UVMHIST_DECL's.
1.7	05-Feb-1998	mrg	initial import of the new virtual memory system, UVM, into -current. UVM was written by chuck cranor <chuck@maria.wustl.edu>, with some minor portions derived from the old Mach code. i provided some help getting swap and paging working, and other bug fixes/ideas. chuck silvers <chuq@chuq.com> also provided some other fixes. this is the rest of the MI portion changes. this will be KNF'd shortly. :-)
1.6	18-May-1996	christos	Support bsdi getkerninfo(SYSINFO,...) call so that the BSDI netscape calling uname(3) can find out what os it is running on. Tested only with a bsdi binary that calls getkerninfo directly. Funny thing is that I ran the same binary on a bsdi machine, and they fill in fewer fields in the emulation than we do; maybe I went overboard :-)
1.5	21-Feb-1996	cgd	fourth argument to kern_sysctl() must be a size_t . simply passing a pointer to SCARG(uap, len) won't do, because that'd be an int . copy the value into a size_t, and pass pointer to that.
1.4	04-Feb-1996	christos	kern_sysctl was missing process argument. Elimited -Wall warnings from the files that were affected
1.3	07-Oct-1995	mycroft	Prefix names of system call implementation functions with `sys_'.
1.2	19-Sep-1995	thorpej	Make system calls conform to a standard prototype and bring those prototypes into scope.
1.1	24-Jun-1995	christos	- Extracted all compat routines from the kern directory and moved here. - Created compat_util.c and compat_util.h to be used by the compatibility modules, so they don't duplicate the same code. - Added prototypes to the stackgap allocation routines.

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.

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.
1.33.4.1	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.

1.25.64.1	22-Sep-2018	pgoyette	#include "opt_compat_netbsd.h" for all sources that provide compat code.
1.6	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 !
1.5	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	27-Jan-2019	pgoyette	Include new header from correct directory
1.3	27-Jan-2019	christos	- autoload the compat_80 for modstat - move compat struct to a compat header
1.2	27-Jan-2019	pgoyette	Merge the [pgoyette-compat] branch
1.1	03-Apr-2018	pgoyette	branches: 1.1.2; file kern_mod_80.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-Sep-2018	pgoyette	#include "opt_compat_netbsd.h" for all sources that provide compat code.
1.1.2.6	18-Sep-2018	pgoyette	The COMPAT_HOOK macros were renamed to MODULE_HOOK, adjust all callers
1.1.2.5	17-Sep-2018	pgoyette	Adapt (most of) the indirect function pointers to the new MP-safe mechanism. Still remaining are the compat_netbsd32 stuff, and some usb subroutines.
1.1.2.4	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.
1.1.2.3	06-Sep-2018	pgoyette	Remove editor glitch
1.1.2.2	06-Sep-2018	pgoyette	Catch up to recent change on head: min() -> uimin()
1.1.2.1	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.

1.21	20-Dec-2007	dsl	branches: 1.21.12; 1.21.90; 1.21.96; 1.21.98; 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.

1.7	30-Mar-2000	augustss	Kill register declarations.
1.6	28-Sep-1999	bouyer	branches: 1.6.2; 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.

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.
1.21.12.2	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.

1.7	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.

1.4	13-Sep-1998	thorpej	branches: 1.4.12; Put the prototypes for native_sig_to_sig() in one place.
1.3	11-Sep-1998	mycroft	Substantial signal handling changes: * Increase the size of sigset_t to accomodate 128 signals -- adding new versions of sys_setprocmask(), sys_sigaction(), sys_sigpending() and sys_sigsuspend() to handle the changed arguments. * Abstract the guts of sys_sigaltstack(), sys_setprocmask(), sys_sigaction(), sys_sigpending() and sys_sigsuspend() into separate functions, and call them from all the emulations rather than hard-coding everything. (Avoids uses the stackgap crap for these system calls.) * Add a new flag (p_checksig) to indicate that a process may have signals pending and userret() needs to do the full (slow) check. * Eliminate SAS_ALTSTACK; it's exactly the inverse of SS_DISABLE. * Correct emulation bugs with restoring SS_ONSTACK. * Make the signal mask in the sigcontext always use the emulated mask format. * Store signals internally in sigaction structures, rather than maintaining a bunch of little sigsets for each SA_* bit. * Keep track of where we put the signal trampoline, rather than figuring it out in _sendsig(). Issue a warning when a non-emulated sigaction bit is observed. * Add missing emulated signals, and a native SIGPWR (currently not used). * Implement the `not reset when caught' semantics for relevant signals. Note: Only code touched by the i386 port has been modified. Other ports and emulations need to be updated.
1.2	29-Nov-1997	kleink	Modify the recent sigaltstack() interface change to use the __RENAME() scheme; add __sigaltstack14().
1.1	25-Nov-1997	kleink	In XPG4.2, the ss_size member of type stack_t (struct sigaltstack) is specified to be of type size_t; since this imposes an interface change on the Alpha (sizeof(int) != sizeof(size_t)), allocate a new system call number and make the previous version a compatibility system call.

1.19.2.2	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.
1.19.2.1	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.

1.7	26-Nov-2021	ryo	Fix anonymous memory object leak for sigcode. - Repeating "modload compat_linux && /emul/linux/bin/ls && modunload compat_linux" will reproduce this problem. - It cause in exec_sigcode_map(), anon-object for sigcode was created at first exec, but it remained even after exec_remove. - Fixed that the anon-object for sigcode is created at exec_add(), and the anon-object reference is removed at exec_remove(). - sigobject_lock is no longer needed since it is locked by exec_lock. - The compat_16 module rewrites the e_sigcode entry in emul_netbsd directly and does not use exec_add()/exec_remove(), so it needs to call sigcode_alloc()/sigcode_free() on its own.
1.6	23-May-2020	ad	Move proc_lock into the data segment. It was dynamically allocated because at the time we had mutex_obj_alloc() but not __cacheline_aligned.
1.5	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.

1.17	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.

1.10	14-Sep-1998	pk	branches: 1.10.6; Fix copyout() arguments.
1.9	11-Sep-1998	mycroft	Substantial signal handling changes: * Increase the size of sigset_t to accomodate 128 signals -- adding new versions of sys_setprocmask(), sys_sigaction(), sys_sigpending() and sys_sigsuspend() to handle the changed arguments. * Abstract the guts of sys_sigaltstack(), sys_setprocmask(), sys_sigaction(), sys_sigpending() and sys_sigsuspend() into separate functions, and call them from all the emulations rather than hard-coding everything. (Avoids uses the stackgap crap for these system calls.) * Add a new flag (p_checksig) to indicate that a process may have signals pending and userret() needs to do the full (slow) check. * Eliminate SAS_ALTSTACK; it's exactly the inverse of SS_DISABLE. * Correct emulation bugs with restoring SS_ONSTACK. * Make the signal mask in the sigcontext always use the emulated mask format. * Store signals internally in sigaction structures, rather than maintaining a bunch of little sigsets for each SA_* bit. * Keep track of where we put the signal trampoline, rather than figuring it out in _sendsig(). Issue a warning when a non-emulated sigaction bit is observed. * Add missing emulated signals, and a native SIGPWR (currently not used). * Implement the `not reset when caught' semantics for relevant signals. Note: Only code touched by the i386 port has been modified. Other ports and emulations need to be updated.
1.8	05-Jul-1998	jonathan	* defopt COMPAT_{09,10,11,12,13} and COMPAT_NOMID. TODO: revisit interaction between native compat and emul compat usage.
1.7	14-Mar-1996	christos	branches: 1.7.14; Fix compiler warnings
1.6	04-Jan-1996	jtc	Changed name of sigaltstack's ss_base field to ss_sp to match XPG4.2 and traditional usage.

1.4	19-Sep-1995	thorpej	Make system calls conform to a standard prototype and bring those prototypes into scope.
1.3	17-Aug-1995	mycroft	Update for signal handling changes.
1.2	15-Aug-1995	mycroft	Rename ss_flags bits.
1.1	24-Jun-1995	christos	- Extracted all compat routines from the kern directory and moved here. - Created compat_util.c and compat_util.h to be used by the compatibility modules, so they don't duplicate the same code. - Added prototypes to the stackgap allocation routines.
1.7.14.1	08-Sep-1997	thorpej	Significantly restructure the way signal state for a process is stored. Rather than using bitmasks to redundantly store the information kept in the process's sigacts (because the sigacts was kept in the u-area), hang sigacts directly off the process, and access it directly. Simplify signal setup code tremendously by storing information in the sigacts as an array of struct sigactions, rather than in a different format, since userspace uses sigactions. Make sigacts sharable by adding reference counting.

1.32.2.2	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.
1.32.2.1	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.

1.35	27-Feb-2020	pgoyette	branches: 1.35.6; 1.35.8; Remove explicit calls to the sysctl setup routines, since this is now handled by the module infrastructure.
1.34	02-Jan-2020	thorpej	branches: 1.34.2; - 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.

1.24	03-Nov-2012	njoly	Move rusage computation to a new getrusage1() function. Adjust all compat/emulations to make use of it.
1.23	02-Oct-2012	christos	kernel portion of clock_nanosleep()
1.22	04-Jan-2012	apb	branches: 1.22.2; 1.22.6; Instead of calling clockctl_ioctl directly, lookup the cdevsw and call its d_ioctl function. This should fix an undefined reference to `clockctlioctl' when you build a kernel that has COMPAT_50 but does not have pseudo-device clockctl.
1.21	04-Jan-2012	apb	Provide a COMPAT_50 version of the CLOCKCTL_NTP_ADJTIME ioctl. When time_t was changed from 32 to 64 bits, this ioctl's number was changed from _IOWR('C', 0x4, struct clockctl_ntp_adjtime) to _IOWR('C', 0x8, struct clockctl_ntp_adjtime), but the data structure did not change, so all the compat code has to do is change the number and try again.
1.20	18-Nov-2011	christos	branches: 1.20.4; add a copyin function for sigset so that we can use sigtimedwait1 from emulations.
1.19	04-Mar-2011	christos	branches: 1.19.4; PR/44674: Taylor R Campbell: Fix compat copyin and copyout routines which were obviously broken.
1.18	19-Jan-2011	tsutsui	branches: 1.18.2; Remove includes <sys/mount.h> and <sys/sched.h> added for <sys/syscallargs.h>. Now they are handled by $sysarghdrextra in sys/kern/syscalls.conf.
1.17	17-Jan-2011	pooka	Put async i/o compat routines in a separate source module from the ones related to clock and process management.
1.16	30-May-2010	drochner	branches: 1.16.2; -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.
1.15	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	19-Jan-2010	pooka	branches: 1.13.2; 1.13.4; Get rid of last "easy" kernel symbols starting with __: __assert -> kern_assert __sigtimedwait1 -> sigtimedwait1 __wdstart -> wdstart1 The rest are MD and/or shared with userspace, so they will require a little more involvement than what is available for this quick "ride the 5.99.24 bump" action.
1.12	11-Nov-2009	rmind	- selcommon/pollcommon: drop redundant l argument. - Use cached curlwp->l_fd, instead of p->p_fd. - Inline selscan/pollscan.
1.11	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 ?).
1.10	12-Oct-2009	yamt	compat_50_sys_aio_suspend: - fix the buffer size. - use kmem_alloc instead of kmem_zalloc for buffers which we will overwrite soon.
1.9	05-Oct-2009	rmind	mq_timedsend/mq_timedreceive: timeout value is absolute, not relative. While here, drop unecessary (since fdesc API changes) lwp_t arguments. Bug reported by Stathis Kamperis, thanks!
1.8	19-Jul-2009	rmind	- Use #ifdef AIO, instead of #ifdef notyet. Not a solution, but at least gets it working for MONOLITHIC kernel. - Similarily add #ifdef MQUEUE for mqueue compat. - Amend TNF license to be 2-clause. Approved by <christos>.
1.7	29-Mar-2009	christos	Move the internal poll/select related API's to use timespec instead of timeval (rides the uvm bump).
1.6	26-Mar-2009	gmcgarry	Replace gcc initialisers with c99 designated initialisers.
1.5	22-Feb-2009	nakayama	- fix copyout size in CLOCKCTL_O?ADJTIME. - add missing break in CLOCKCTL_NTP_ADJTIME.

1.3	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.

1.4	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 !
1.3	27-Sep-2019	pgoyette	Actually return the updated pointer-to-mbuf-pointer to the caller rather than discarding-after-assignment. Introduced from the [pgoyette-compat] branch work.

1.1	15-Apr-2019	pgoyette	Split the COMPAT_50 socket-timeout stuff out of kern/uipc_socket.c and into its own source file, which is now included in the compat_50 module. (Not sure how this got missed during the original [pgoyette-compat] work)
1.2.6.1	21-Oct-2019	martin	Pull up following revision(s) (requested by pgoyette in ticket #339): sys/compat/common/kern_uipc_socket_50.c: revision 1.3 sys/sys/compat_stub.h: revision 1.19 sys/kern/uipc_socket.c: revision 1.284 Actually return the updated pointer-to-mbuf-pointer to the caller rather than discarding-after-assignment.

1.17	01-Jan-2020	thorpej	branches: 1.17.2; - Introduce a new global kernel variable "shutting_down" to indicate that the system is shutting down or rebooting. - Set this global in a new function called kern_reboot(), which is currently just a basic wrapper around cpu_reboot(). - Call kern_reboot() instead of cpu_reboot() almost everywhere; a few places remain where it's still called directly, but those are in early pre-main() machdep locations. Eventually, all of the various cpu_reboot() functions should be re-factored and common functionality moved to kern_reboot(), but that's for another day.

1.13	20-Dec-2007	dsl	branches: 1.13.6; 1.13.8; 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.

It is currently silently ignored on all other hardware now, however. The MD function "boot()" has been changed to also take a char *.

1.14.4.2	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.
1.14.4.1	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.

Now, the minimal compat code can be successfully loaded and unloaded along with the rest of the COMPAT_90 code. Allow kernels builds which don't define INET6 to compile compat bits too. Default the build of compat_90 module to include IPv6, as is done for other INET6-sensitive modules (see if_lagg).

Thus, rtsock_14.c is included in the kernel. rtsock_14.c in turn references routines in rtsock_50.c which is also included in the kernel. However, if the kernel is built without the COMPAT_50 option, rtsock_50.c ends up being a no-op and doesn't define any of the routines that rtsock_14.c needs. Thus, MODULAR kernels which only have COMPAT_60 (or newer) will fail to link becuase of the undefined symbols. Fix is to make rtsock_50.c functional if MODULAR kernel option is specified.

1.6.2.3	13-Jan-2019	pgoyette	Add the required hooks for rtsock_50 and modify the COMPATCALL() macro to use the hooks. While the rtsock_50 situation is still sub-optimal (it includes the main rtsock.c with a whole bunch of function and variable redefinitions via macros), this at least makes it possible to load the rtsock_50 code separately from more recent code, rather than the previous requirement that rtsock_50 be built-in.
1.6.2.2	11-Jan-2019	pgoyette	Rework the various sysctl-related routines to call the correct code for each version. While here, extract the 5.0 specific code instead of including in the main rtsock.c code. Also, clean up all the sysctl-related routines to prevent building more than one copy, no matter how many places rtsock.c gets #include'd into!

1.8	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 !
1.7	29-Apr-2019	pgoyette	Move the set-up of the net.oroute... sysctl tree to compat_50 since the new AF_ROUTE was introduced in NetBSD-6.0
1.6	29-Apr-2019	pgoyette	For the rtsock compat code, make sure we create the "oroute" sysctl tree. Otherwise a 5.2 version of getifaddrs(2) gets errors. This makes the 5.2 version of ifconfig(8) behave the same on both NetBSD-8 and -current. HOWEVER, both of them print nothing (for ``ifconfig -l'' command) so there's still a bug somewhere. As reported originally by der Mouse.
1.5	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.
1.4	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.

1.2.2.5	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.
1.2.2.4	14-Jan-2019	pgoyette	Create a variant of the HOOK macros that handles hook routines of type void, and use them where appropriate.
1.2.2.3	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.
1.2.2.2	15-Oct-2018	pgoyette	Convert a couple more hooks to the MP-safe mechanism. While here, clean up some headers and remove any that are now empty.
1.2.2.1	15-Mar-2018	pgoyette	Create a separate module for COMPAT_70 code only, and untangle the 70 compat code from the current.

1.5	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!)
1.4	03-Dec-2015	pgoyette	branches: 1.4.16; 1.4.18; Add comment to #ifdef - it's a long way from its original #if
1.3	10-May-2015	pgoyette	Split the SYSV* compat code out into a separate compat_sysv module. For monolithic kernels, both modules will be compiled as "built-ins", while modular environments will be able to load the SYSVSEM, SYSVSHM, and SYSVMSG code independant from the rest of compat. This is a necessary precursor step to making the "STD" SYSV* code into a separate module. Tested in both monolithic and modular environments with no errors seen.

1.17.2.2	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.
1.17.2.1	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.

All user-visible changes are protected with #if !defined(_POSIX_C_SOURCE) && !defined(_XOPEN_SOURCE) Make all variable declarations extern in msg.h, sem.h and shm.h and add relevent variable declarations to sysv_.c and remove unneeded header files from those .c files. Make compat14 SysV IPC conversion functions and sysctl_file() static. Change the data pointer to "void " in sysctl_clockrate(), sysctl_ntptime(), sysctl_file() and sysctl_doeproc().

1.15.2.2	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.
1.15.2.1	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.

1.40	10-Jul-2022	riastradh	tty_43: Do unsigned arithmetic to avoid shift into sign bits. Omit input validation -- it's not a great idea for compatibility with historical kernels, since they ignored the bits instead of rejecting them if set. With unsigned arithmetic, we get the same semantics as was previously assumed (discarding bits that get shifted into the sign bit or off into oblivion) without the formal undefined behaviour. Reported-by: syzbot+e408764cdd8c0c0ff535@syzkaller.appspotmail.com https://syzkaller.appspot.com/bug?id=8318f0039e68187cd8d27b2c520816fff3f7266a
1.39	10-Oct-2020	christos	TIOCGSID is used by tcgetsid() so it is not really compat :-) This should reduce loading the compat module.
1.38	09-Oct-2020	nia	tty_43: Check a bitset from userspace is valid before shifting it Passing a negative value to these legacy compat ioctls results in left shift on a negative value which is undefined behaviour and results in the tty (at least, possibly other things) locking up. The argument to the ioctl should always be > 0. Return EINVAL otherwise. While here, adjustments to code style to match current guidelines. Found by UBSan. Reported-by: syzbot+39cd551a05298b222756@syzkaller.appspotmail.com
1.37	08-Aug-2020	christos	Fix the OTIOCGETD emulation. Line discipline 0 is NTTYDISC.
1.36	23-May-2020	ad	Move proc_lock into the data segment. It was dynamically allocated because at the time we had mutex_obj_alloc() but not __cacheline_aligned.
1.35	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 !
1.34	01-Mar-2019	pgoyette	branches: 1.34.4; Rename the MODULE__HOOK() macros to MODULE_HOOK_() as briefly discussed on irc. NFCI intended. Ride the earlier kernel bump - it;s getting crowded.
1.33	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.
1.32	28-Jan-2019	christos	- provide a hook for the 43 tty ioctls - make the 60 tty ioctl hook look the same - fix the tty code to call both hooks and remove unused lock

1.28	14-Nov-2008	ad	- Move some more compat code into sys/compat. - Split 4.3BSD ifioctl stuff into its own file. - Remove some ifdefs that include small fragments of vfs compat code which are difficult to relocate elsewhere.

1.26	24-Apr-2008	ad	branches: 1.26.2; 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.

1.19	27-Nov-2005	thorpej	Overhaul how TTY line disciplines are handled: - Replace references to linesw[0] with a ttyldisc_default() function that returns the default ("termios") line discipline. - The linesw[] array is gone, replaced by a linked list. - ttyldisc_add() and ttyldisc_remove() have been replaced by ttyldisc_attach() and ttyldisc_detach(). - Things that provide line disciplines are now responsible for registering those disciplines with the system. The linesw structures are no longer declared in tty_conf.c - Line disciplines are now refcounted; a lookup causes a reference to be held. ttyldisc_release() releases the reference. Attempts to detach an in-use line discipline result in EBUSY. - Fix function signature lossage in if_sl.c, if_strip.c, and tty_tb.c that was masked by the old tty_conf.c - tty_init() is no longer necessary; delete it and its call from main().

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
1.14	17-Mar-2002	atatat	Convert ioctl code to use EPASSTHROUGH instead of -1 or ENOTTY for indicating an unhandled "command". ERESTART is -1, which can lead to confusion. ERESTART has been moved to -3 and EPASSTHROUGH has been placed at -4. No ioctl code should now return -1 anywhere. The ioctl() system call is now properly restartable.

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.

The argument to the ioctl should always be > 0. Return EINVAL otherwise. While here, adjustments to code style to match current guidelines. Found by UBSan.
1.34.4.1	10-Oct-2020	martin	Pull up following revision(s) (requested by nia in ticket #1106): sys/compat/common/tty_43.c: revision 1.38 tty_43: Check a bitset from userspace is valid before shifting it Passing a negative value to these legacy compat ioctls results in left shift on a negative value which is undefined behaviour and results in the tty (at least, possibly other things) locking up.

1.11	21-Jul-2021	skrll	need <sys/param.h> for COHERENCY_UNIT Minor KNF along the way.
1.10	24-Jun-2020	jdolecek	branches: 1.10.6; reduce stack usage in compat_60_ptmget_ioctl() - allocate struct ptmget via kmem_alloc()
1.9	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 !
1.8	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.
1.7	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.
1.6	28-Jan-2019	christos	- provide a hook for the 43 tty ioctls - make the 60 tty ioctl hook look the same - fix the tty code to call both hooks and remove unused lock
1.5	27-Jan-2019	pgoyette	Merge the [pgoyette-compat] branch
1.4	22-Oct-2015	christos	branches: 1.4.2; 1.4.8; 1.4.16; 1.4.18; Handle both ioctls in both places :-)

1.2	19-Oct-2012	apb	This file getscompiled even if COMPAT_60 is not defined, so protect most of the contents with #ifdef COMPAT_60
1.1	19-Oct-2012	apb	Add COMPAT_60 versions of the TIOCPTMGET and TIOCPTSNAME ioctls.

1.4.18.1	10-Jun-2019	christos	Sync with HEAD
1.4.16.7	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.
1.4.16.6	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.
1.4.16.5	15-Oct-2018	pgoyette	Convert another hook to the MP-sfe mechanism. XXX still have three more to convert: openat_10, sysvipc50_sysctl and XXX compat70_unp_addsockcred
1.4.16.4	04-Sep-2018	pgoyette	Separate COMPAT_BSDPTY stuff from tty COMPAT_60 stuff. Enables building of COMPAT_60 module whether or not COMPAT_BSDPTY is defined in the kernel.
1.4.16.3	18-Mar-2018	pgoyette	Merge changes from HEAD into ccd_60.c For all of the individual xxx_60_{init,fini} routines, don't force them to artificially return a status; just make them void. This simplifies the compat_60_{init,fini} handling of errors that remain.
1.4.16.2	18-Mar-2018	pgoyette	Initial pass at getting the tty stuff properly modularized. Subject to review and revision.
1.4.16.1	08-Mar-2018	pgoyette	We don't need to conditionalize the code on COMPAT_60 since we'll only include the source file when COMPAT_60 is requested (either by kernel option or module specification)
1.4.8.1	27-Apr-2017	pgoyette	Restore all work from the former pgoyette-localcount branch (which is now abandoned doe to cvs merge botch). The branch now builds, and installs via anita. There are still some problems (cgd is non-functional and all atf tests time-out) but they will get resolved soon.
1.4.2.1	20-Jul-2016	pgoyette	Adapt machine-independant code to the new {b,c}devsw reference-counting (using localcount(9)). All callers of {b,c}devsw_lookup() now call {b,c}devsw_lookup_acquire() which retains a reference on the 'struct {b,c}devsw'. This reference must be released by the caller once it is finished with the structure's content (or other data that would disappear if the 'struct {b,c}devsw' were to disappear).

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.

1.3.12.2	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.
1.3.12.1	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	07-Jul-2022	riastradh	ifioctl(9): Don't touch ifconf or ifreq until command is validated. sys_ioctl validates the data pointer according to the command's size and direction. But userland may ioctl commands other than OSIOCGIFCONF or OOSIOCGIFCONF -- and if userland passes an IOC_VOID command, the argument is passed through verbatim and may be null.

1.13	14-Mar-2017	ozaki-r	branches: 1.13.6; Use if_acquire and if_release instead of using psref API directly - Provide if_release for consistency to if_acquire - Use if_acquire and if_release for ifp iterations - Make ifnet_psref_class static
1.12	01-Aug-2016	ozaki-r	branches: 1.12.2; Apply pserialize and psref to struct ifaddr and its variants This change makes struct ifaddr and its variants (in_ifaddr and in6_ifaddr) MP-safe by using pserialize and psref. At this moment, pserialize_perform and psref_target_destroy are disabled because (1) we don't need them because of softnet_lock (2) they cause a deadlock because of softnet_lock. So we'll enable them when we remove softnet_lock in the future.
1.11	07-Jul-2016	ozaki-r	branches: 1.11.2; Switch the address list of intefaces to pslist(9) As usual, we leave the old list to avoid breaking kvm(3) users.

1.9	12-May-2016	ozaki-r	Protect ifnet list with psz and psref The change ensures that ifnet objects in the ifnet list aren't freed during list iterations by using pserialize(9) and psref(9). Note that the change adds a pslist(9) for ifnet but doesn't remove the original ifnet list (ifnet_list) to avoid breaking kvm(3) users. We shouldn't use the original list in the kernel anymore.
1.8	26-Nov-2014	ozaki-r	branches: 1.8.2; Tweak ifconf variants The tweaks make the code intention clear and make further changes easy. No functional change.

However, the actual assignment of the address (ifa_insert) is out of in6_ifinit. The check and the assignment must be done atomically. Fix it by holding in6_ifaddr_lock during in6_ifinit and ifa_insert. And also add missing pserialize to IFADDR_READER_FOREACH.

1.15.2.10	20-Sep-2018	pgoyette	Use the MP-safe hooks mechanism for the uipc_syscalls_40 and _50 routines.
1.15.2.9	16-Apr-2018	pgoyette	Rename if_[45]0_{init,fini} entry points to more appropriate and more consistent uipc_syscalls_[45]0_{init,fini} and remove some multiple declarations.
1.15.2.8	16-Apr-2018	pgoyette	Sync with HEAD, resolve some conflicts
1.15.2.7	15-Apr-2018	pgoyette	Make compat_ifconf() and compat_ifdatareq() static
1.15.2.6	12-Apr-2018	pgoyette	Merge christos's recent changes on HEAD
1.15.2.5	08-Mar-2018	pgoyette	Remove unnecessary conditionals. These files aren't built unless their content is needed (via config option or module configuration).
1.15.2.4	08-Mar-2018	pgoyette	Handle ifconf() compat vectors
1.15.2.3	06-Mar-2018	pgoyette	Use a .h file for declaring the if_40_{init, fini} routines
1.15.2.2	06-Mar-2018	pgoyette	Typo in function declaration.
1.15.2.1	06-Mar-2018	pgoyette	Untangle some networking compat code so we can build a kernel with networking and MODULAR, but without any actual COMPAT_* code (ie, assuming that all the compat stuff can be added later via modules).
1.16.2.2	08-Apr-2020	martin	Merge changes from current as of 20200406
1.16.2.1	10-Jun-2019	christos	Sync with HEAD
1.20.2.1	17-Jul-2020	martin	Pull up following revision(s) (requested by msaitoh in ticket #1018): sys/net/if.c: revision 1.479 sys/compat/common/uipc_syscalls_40.c: revision 1.23 sys/compat/linux/common/linux_socket.c: revision 1.150 sys/compat/linux32/common/linux32_socket.c: revision 1.31 Don't accept negative value.
1.21.2.1	29-Feb-2020	ad	Sync with head.
1.51	27-Jan-2019	pgoyette	Merge the [pgoyette-compat] branch
1.50	06-Sep-2018	maxv	Remove the network ATM code.
1.49	03-May-2018	christos	branches: 1.49.2; 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...
1.48	16-Mar-2018	christos	PR/53103: Timo Buhrmester: linux emulation of sendto(2) broken The sockargs refactoring broke it, because sockargs only works with a user address. Added an argument to sockargs to indicate where the address is coming from. Welcome to 8.99.14.
1.47	13-Sep-2016	martin	branches: 1.47.14; 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.
1.46	09-Nov-2014	maxv	branches: 1.46.2; Do not uselessly include <sys/malloc.h>.
1.45	05-Sep-2014	matt	Try not to use f_data, use f_{vnode,socket,pipe,mqueue,kqueue,ksem} to get a correctly typed pointer.
1.44	14-Nov-2008	ad	branches: 1.44.26; 1.44.42; - Move some more compat code into sys/compat. - Split 4.3BSD ifioctl stuff into its own file. - Remove some ifdefs that include small fragments of vfs compat code which are difficult to relocate elsewhere.
1.43	29-Apr-2008	ad	branches: 1.43.2; 1.43.6; 1.43.8; 1.43.10; Remove now bogus assertion.
1.42	24-Apr-2008	ad	branches: 1.42.2; Merge the socket locking patch: - Socket layer becomes MP safe. - Unix protocols become MP safe. - Allows protocol processing interrupts to safely block on locks. - Fixes a number of race conditions. With much feedback from matt@ and plunky@.
1.41	15-Jan-2008	martin	branches: 1.41.6; #ifdef COMPAT_20 the ioctls only available conditionally. Patch from Geoff Wing.
1.40	14-Jan-2008	martin	Add net80211 ioctls that I apparently ovelooked when grepping for ioctls that need "struct ifreq" compat treatment. This makes for example old (like 4.0) wpa_supplicant work with -current kernels.
1.39	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.
1.38	08-Dec-2007	dsl	branches: 1.38.4; ANSIfy most of the function definitions in sys/compat (but not ndis). All by the magic of sed ...
1.37	11-Sep-2007	gdt	branches: 1.37.6; 1.37.8; remove SIOCSIFALIFETIME_IN6 (should have been part of previous commit)
1.36	20-Aug-2007	martin	branches: 1.36.2; Remove all ioctls from the conversion list that are explicitly defined to use struct oifreq - the magic size changing makes them fail.
1.35	20-Aug-2007	martin	Sigh - revert previous. Seems we can't avoid the big list, so fill it. Now both "ifconfig ... create" and "pppoectl -d" work again with old userland.
1.34	20-Aug-2007	martin	Put back the previous hack to make compat_cvtcmd() work for all the ioctls that use struct ifreq which have not been explicitly versioned. If someone feels like fixing it with a list aproach, I think below is a complete list - the one used in the previous version missed a lot of them.

1.33	20-Aug-2007	skd	Clean up net compat ioctls, and clean up handling of wireless ioctls.
1.32	30-Jun-2007	dsl	branches: 1.32.2; 1.32.6; Changes to sompat socket function to avoid the dreaded stackgap.
1.31	24-Jun-2007	dsl	Update to call do_sys_recv() instead of recvit().
1.30	01-Jun-2007	dsl	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.
1.29	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.
1.28	04-Mar-2007	christos	branches: 1.28.2; 1.28.4; Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.
1.27	09-Feb-2007	ad	branches: 1.27.2; Merge newlock2 to head.
1.26	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.
1.25	11-Dec-2005	christos	branches: 1.25.20; merge ktrace-lwp.
1.24	24-Sep-2005	christos	factor out some of the osockaddr, omsghdr code.
1.23	26-Feb-2005	perry	branches: 1.23.4; nuke trailing whitespace
1.22	07-Aug-2003	agc	branches: 1.22.8; 1.22.10; Move UCB-licensed code from 4-clause to 3-clause licence. Patches provided by Joel Baker in PR 22364, verified by myself.
1.21	29-Jun-2003	fvdl	branches: 1.21.2; Back out the lwp/ktrace changes. They contained a lot of colateral damage, and need to be examined and discussed more.
1.20	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
1.19	18-Jan-2003	thorpej	Merge the nathanw_sa branch.
1.18	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.
1.17	13-Nov-2001	lukem	add RCSIDs (including regeneration of files as appropriate)
1.16	22-Jul-2001	jdolecek	return EMSGSIZE rather than ENOMEM if it would not be possible to allocate space for accrights within stackgap comment the copyin() of msg.msg_control in recvmsg() is safe
1.15	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.
1.14	07-Jul-2001	jdolecek	branches: 1.14.2; compat_43_sys_send(): wrap using sys_sendto() rathen than sendit() compat_43_sys_recv(): wrap using sys_recvfrom() rathen than recvit()
1.13	25-Jun-2001	jdolecek	Back off the sendit()/recvit() change, some have problems with it
1.12	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.
1.11	30-Mar-2000	augustss	branches: 1.11.6; Kill register declarations.
1.10	18-Dec-1998	drochner	branches: 1.10.8; solve the COMPAT_OLDSOCK/MSG_COMPAT problem differently: The source files which need MSG_COMPAT define COMPAT_OLDSOCK.
1.9	18-Dec-1998	mrg	back out previous; it breaks when MSG_COMPAT is not defined (no compatibility modules)
1.8	14-Dec-1998	mycroft	Nuke some #ifdefs that no longer work with COMPAT_43 defopted.
1.7	04-Aug-1998	kleink	UIO_MAXIOV -> IOV_MAX
1.6	03-Aug-1998	kleink	Fix two off-by-one bugs, both present in each recvmsg(2) and sendmsg(2): * the first one would cause an unnecessary malloc() of iovec storage for a msg_iovlen of UIO_SMALLIOV although the required amount of memory has been allocated on the stack. * the second one would cause a recvmsg() or sendmsg() with a msg_iovlen of UIO_MAXIOV to fail with EMSGSIZE, which is also a violation of XNS5.
1.5	14-Mar-1996	christos	Fix compiler warnings
1.4	10-Feb-1996	christos	Don't declare MSG_COMPAT in two places. More prototype fixes
1.3	07-Oct-1995	mycroft	Prefix names of system call implementation functions with `sys_'.
1.2	19-Sep-1995	thorpej	Make system calls conform to a standard prototype and bring those prototypes into scope.
1.1	24-Jun-1995	christos	- Extracted all compat routines from the kern directory and moved here. - Created compat_util.c and compat_util.h to be used by the compatibility modules, so they don't duplicate the same code. - Added prototypes to the stackgap allocation routines.

1.21.2.1	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.

Instead provide a switch. Keep the old code there, to handle cases we did not handle in the first switch, but this is a hack and should be removed.
1.43.8.1	19-Jan-2009	skrll	Sync with HEAD.
1.43.6.1	13-Dec-2008	haad	Update haad-dm branch to haad-dm-base2.
1.43.2.2	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.
1.43.2.1	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.

1.3.56.13	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.

1.1.20.5	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).

1.1.2.6	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.

1.1.2.2	18-Sep-2018	pgoyette	Split the COMPAT_CALL_HOOK to separate the declaration from the implementation. Some hooks are called from multiple source files, and the old method resulted in duplicate implementations. Implement MP-safe hooks for the usb_subr_30 code. Pass the helper functions as arguments to the compat code so it does not have to determine if the kernel contains usb code.

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@

1.3	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.

1.1.2.5	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.

1.38	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.
1.37	27-Jan-2019	pgoyette	branches: 1.37.4; Merge the [pgoyette-compat] branch
1.36	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!)

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.

1.12	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	13-Nov-2001	lukem	add RCSIDs (including regeneration of files as appropriate)
1.9	14-Jun-2001	thorpej	branches: 1.9.2; 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.
1.8	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@.
1.7	07-Apr-2001	jdolecek	Add new 'stat' fileop and call the stat function via f_ops rather than directly. For compat syscalls, also add necessary FILE_USE()/FILE_UNUSE(). Now that soo_stat() gets a proc arg, pass it on to usrreq function.
1.6	30-Mar-2000	augustss	branches: 1.6.6; Kill register declarations.
1.5	05-May-1999	thorpej	branches: 1.5.2; 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.
1.4	30-Mar-1999	wrstuden	branches: 1.4.4; Explicitly mask mode returned in old stat structure to 16 bits. Also correct comment (we're converting from a new to an old struct stat).

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.

1.25.8.2	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.
1.25.8.1	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.

1.30	06-May-2008	ad	branches: 1.30.2; 1.30.4; 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.
1.29	05-May-2008	ad	Remove unneeded includes.
1.28	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.
1.27	29-Apr-2008	ad	kern/38135 vfs_busy/vfs_trybusy confusion The symptom was that sometimes file systems would occasionally not appear in output from 'df' or 'mount' if the system was busy. Resolution: - Make mount locks work somewhat like vm_map locks. - vfs_trybusy() now only fails if the mount is gone, or if someone is unmounting the file system. Simple contention on mnt_lock doesn't cause it to fail. - vfs_busy() will wait even if the file system is being unmounted.

1.17	22-Apr-2007	dsl	branches: 1.17.6; 1.17.8; 1.17.10; 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.

1.30.2.2	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.
1.30.2.1	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.

1.37	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!)

1.33	19-Nov-2010	dholland	branches: 1.33.18; 1.33.34; Introduce struct pathbuf. This is an abstraction to hold a pathname and the metadata required to interpret it. 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.
1.32	24-Jun-2010	hannken	Clean up vnode lock operations pass 2: VOP_UNLOCK(vp, flags) -> VOP_UNLOCK(vp): Remove the unneeded flags argument. Welcome to 5.99.32. Discussed on tech-kern.

This fix is similar to nfs_serv.c revisions 1.115 + 1.124. This should fix the long-standing problem observed by e.g. using Linux- emulated programs to take backup of servers, which is one of the problems which were reported in PR#42661.

1.24	08-Dec-2007	pooka	branches: 1.24.4; 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.
1.23	30-Apr-2007	dsl	branches: 1.23.6; 1.23.8; 1.23.16; 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.
1.22	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.

1.7	01-Mar-2006	yamt	branches: 1.7.2; 1.7.4; 1.7.6; 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.

1.27.2.2	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.
1.27.2.1	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.

1.63	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!)

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.

1.38	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	14-Jun-2001	thorpej	branches: 1.19.2; 1.19.4; 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.

1.19.4.1	18-Sep-2001	fvdl	Various changes to make cloning devices possible: * Add an extra argument (struct vnode *) to VOP_OPEN. If it is not NULL, specfs will create a cloned (aliased) vnode during the call, and return it there. The caller should release and unlock the original vnode if a new vnode was returned. The new vnode is returned locked. Add a flag field to the cdevsw and bdevsw structures. DF_CLONING indicates that it wants a new vnode for each open (XXX is there a better way? devprop?) * If a device is cloning, always call the close entry point for a VOP_CLOSE. Also, rewrite cons.c to do the right thing with vnodes. Use VOPs rather then direct device entry calls. Suggested by mycroft@ Light to moderate testing done an i386 system (arch doesn't matter though, these are MI changes).

1.46.6.2	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.
1.46.6.1	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.

1.18	05-Sep-2014	matt	branches: 1.18.12; 1.18.18; 1.18.20; Try not to use f_data, use f_{vnode,socket,pipe,mqueue,kqueue,ksem} to get a correctly typed pointer.
1.17	13-Mar-2012	elad	branches: 1.17.2; Replace the remaining KAUTH_GENERIC_ISSUSER authorization calls with something meaningful. All relevant documentation has been updated or written. Most of these changes were brought up in the following messages: http://mail-index.netbsd.org/tech-kern/2012/01/18/msg012490.html http://mail-index.netbsd.org/tech-kern/2012/01/19/msg012502.html http://mail-index.netbsd.org/tech-kern/2012/02/17/msg012728.html Thanks to christos, manu, njoly, and jmmv for input. Huge thanks to pgoyette for spinning these changes through some build cycles and ATF.
1.16	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.
1.15	29-Jan-2012	dholland	Some further tidying for the COMPAT_50 quotactl code. Mostly cosmetic, but also use PNBUF_GET() and PNBUF_PUT() for a path buffer instead of malloc with M_TEMP.
1.14	29-Jan-2012	dholland	Remove the proplib goop from the COMPAT_50 code for the old quotactl; use the new VFS_QUOTACTL instead.
1.13	29-Jan-2012	dholland	Rename static inline "helper" functions: ufsclass2qtype -> quota_idtype_to_ufs qtype2ufsclass -> quota_idtype_from_ufs The reason for the direction of "ufs" changing is that the old names were among the symbols using "ufs" to mean "fs-independent". So the old names were for translating "ufsclass" (fs-independent quota id type) to "qtype" (ufs-specific quota id type) and vice versa. These functions are used in only two places, both of which are inappropriate, so at some point they should probably be removed. They're also identity transformations so not particularly helpful, unless one were to make a careful and concerted effort to distinguish the ufs quota code numbers from the fs-independent ones. This has not been done and is probably impossible without support from a program verifier, and maybe not even then. They are static inline, so no compat concerns arise. Also adjust the symbols they use to avoid <quota/quotaprop.h>.
1.12	29-Jan-2012	dholland	Add vfs_quotactl() in between the syscall and VFS_QUOTACTL. Call it from the COMPAT_50 code as well as the current sys_quotactl instead of going directly to VFS_QUOTACTL. Doesn't actually do anything yet.
1.11	29-Jan-2012	dholland	Change dqblk_to_quotaval() from quota1_subr.c to dqblk_to_quotavals(), and pass in two single quotaval structs (for blocks and inodes) instead of an array of (implicitly) QUOTA_NLIMITS quotaval structs indexed by constants from quotaprop.h. Note: because this code is used by COMPAT_50 as well as ufs, this change requires a kernel version bump. (The code is also used by edquota, but via .PATH so it's not ABI-sensitive there.)
1.10	25-Nov-2011	dholland	branches: 1.10.2; Rename struct ufs_quota_entry -> struct quotaval.
1.9	20-Nov-2011	dholland	Reshuffle decls among the quota headers so everything is in the place it should be: - stuff for the proplib interface goes in <quota/quotaprop.h> - stuff for userlevel only goes in <quota/quota.h> - stuff shared between user and kernel goes in <sys/quota.h> Note that <quota/quota.h> and <quota/quotaprop.h> are expected to be moved or removed later on... one thing at a time. Update include directives in other files as needed.
1.8	24-Mar-2011	bouyer	branches: 1.8.4; Add a new libquota library, which contains some blocks to build and/or parse quota plists; as well as a getfsquota() function to retrieve quotas for a single id from a single filesystem (whatever filesystem this is: a local quota-enabled fs or NFS). This is build on functions getufsquota() (for local filesystems with UFS-like quotas) and getnfsquota(); which are also available to userland programs. move functions from quota2_subr.c to libquota or libprop as appropriate, and ajust in-tree quota tools. move some declarations from kernel headers to either sys/quota.h or quota/quota.h as appropriate. ufs/ufs/quota.h still installed because it's needed by other installed ufs headers. ufs/ufs/quota1.h still installed as a quick&dirty way to get a code using the old quotactl() to compile (just include ufs/ufs/quota1.h instead of ufs/ufs/quota.h - old code won't compile without this change and this is on purpose). Discussed on tech-kern@ and tech-net@ (long thread, but not much about libquota itself ...)
1.7	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.

1.17.12.2	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.

1.16.32.1	05-Mar-2011	rmind	sync with head
1.16.12.2	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.
1.16.12.1	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.

1.20.8.2	22-Sep-2018	pgoyette	#include "opt_compat_netbsd.h" for all sources that provide compat code.
1.20.8.1	17-Apr-2018	pgoyette	First pass at compat modules for 4.3BSD, NetBSD-0.9, and NetBSD-1.0 XXX Still need to deal with the sysctl stuff and other code shared XXX between 09 and 43
1.7	16-Oct-1997	christos	Rename to vm_12.c
1.6	10-Oct-1997	mrg	remove advertising clause from all my licenses.
1.5	13-Jun-1997	thorpej	branches: 1.5.4; Don't #ifdef compat_12_sys_swapon() so that it can be used by other compat modules.
1.4	12-Jun-1997	mrg	put the front end into libc.
1.3	12-Jun-1997	mrg	make this sys_swapon() for now.
1.2	12-Jun-1997	mrg	bring mrg-vm-swap2 onto mainline.
1.1	14-Feb-1997	mrg	branches: 1.1.2; file vm_swap_12.c was initially added on branch mrg-vm-swap.
1.1.2.2	14-Feb-1997	mrg	branches: 1.1.2.2.2; make this more likely to work; follow naming conventions
1.1.2.1	14-Feb-1997	mrg	emulate old swapon().
1.1.2.2.2.3	01-Jun-1997	mrg	it is called sys_swapctl() now.
1.1.2.2.2.2	06-May-1997	pk	Cast away `const' from old swapon's `name' argument. Include <sys/systm.h>
1.1.2.2.2.1	06-May-1997	mrg	add <sys/syscallargs.h> as required, and <sys/mount.h> as previous requires.
1.5.4.1	14-Oct-1997	thorpej	Update marc-pcmcia branch from trunk.
1.4	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 !
1.3	01-Mar-2019	pgoyette	branches: 1.3.4; Rename the MODULE__HOOK() macros to MODULE_HOOK_() as briefly discussed on irc. NFCI intended. Ride the earlier kernel bump - it;s getting crowded.
1.2	27-Jan-2019	pgoyette	Merge the [pgoyette-compat] branch
1.1	28-Mar-2018	pgoyette	branches: 1.1.2; file vnd_30.c was initially added on branch pgoyette-compat.
1.1.2.5	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.
1.1.2.4	22-Sep-2018	pgoyette	#include "opt_compat_netbsd.h" for all sources that provide compat code.
1.1.2.3	18-Sep-2018	pgoyette	The COMPAT_HOOK macros were renamed to MODULE_HOOK, adjust all callers
1.1.2.2	17-Sep-2018	pgoyette	Adapt (most of) the indirect function pointers to the new MP-safe mechanism. Still remaining are the compat_netbsd32 stuff, and some usb subroutines.
1.1.2.1	28-Mar-2018	pgoyette	Split vnd compat_30 code out of the main driver and into the compat_30 module
