 1.18  25-Nov-2021  ryo - Add compat_linux statx(2) syscall.
- The AT_EMPTY_PATH processing from the modification of
sys/compat/linux/common/linux_file64.c r1.63 has been separated, and made
common to linux_statat(), so that it can be used not only by
linux32_sys_fstatat64() but also by other *statat() variants.
 1.17  18-Nov-2013  chs implement the *at() syscalls.
bring the unimplemented syscall list up to date.
 1.16  04-Jun-2009  njoly branches: 1.16.12; 1.16.22; 1.16.26;
Add stat/lstat/fstat syscalls.
 1.15  03-Jun-2009  njoly Cleanup (no functional changes).
Kill some unneeded variables and return stattement.
Rename linux32_from_stat() to better bsd_to_linux32_stat64().
Fix some types.
 1.14  03-Jun-2009  njoly Fix inverted lst_ino/__lst_ino assignment in linux32_from_stat().
 1.13  18-Mar-2009  cegger bzero -> memset
 1.12  19-Nov-2008  ad branches: 1.12.4;
Make the emulations, exec formats, coredump, NFS, and the NFS server
into modules. By and large this commit:

- shuffles header files and ifdefs
- splits code out where necessary to be modular
- adds module glue for each of the components
- adds/replaces hooks for things that can be installed at runtime
 1.11  21-Mar-2008  ad branches: 1.11.4; 1.11.6; 1.11.10; 1.11.12; 1.11.14;
Catch up with descriptor handling changes. See kern_descrip.c revision
1.173 for details.
 1.10  20-Dec-2007  dsl branches: 1.10.6;
Convert all the system call entry points from:
int foo(struct lwp *l, void *v, register_t *retval)
to:
int foo(struct lwp *l, const struct foo_args *uap, register_t *retval)
Fixup compat code to not write into 'uap' and (in some cases) to actually
pass a correctly formatted 'uap' structure with the right name to the
next routine.
A few 'compat' routines that just call standard ones have been deleted.
All the 'compat' code compiles (along with the kernels required to test
build it).
98% done by automated scripts.
 1.9  08-Dec-2007  dsl branches: 1.9.4;
ANSIfy most of the function definitions in sys/compat (but not ndis).
All by the magic of sed ...
 1.8  22-Apr-2007  dsl branches: 1.8.6; 1.8.8; 1.8.16;
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  18-Mar-2007  dsl Change all the NETBSD32PTR64(SCARG(uap, xxx))) to SCARG_P32(uap, xxx).
 1.6  16-Mar-2007  dsl remove all the double (and triple) casts used to convert 32bit userspace
pointers to and from 64bit kernel pointers. Instead use the defines
NETBSD32PTR64(p32) to read a 32bit pointer and (the new) NETBSD32PTR32(p32,p64)
to write a 32bit pointer throughout.
The 32bit pointer is now a struct to enforce the above.
amd64 (with linux emul) and sparc64 will both compile (when the arch stuff
goes in soon), and amd64 still runs some i386 binaries.
 1.5  11-Mar-2007  dsl branches: 1.5.2; 1.5.4;
Fix amd64 build for compat sys_stat() changes.
This file isn't included in amd64:GENERIC
 1.4  10-Mar-2007  dsl 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.
 1.3  04-Mar-2007  christos branches: 1.3.2;
Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.
 1.2  09-Feb-2007  ad branches: 1.2.2;
Merge newlock2 to head.
 1.1  09-Feb-2006  manu branches: 1.1.2; 1.1.10; 1.1.16; 1.1.20; 1.1.22;
Add initial (but unfinished) COMPAT_LINUX32 for amd64. This is good enough so
that the i386 license manager part of amd64 version of Fluent works.

While I'm here, add SysV IPC to COMPAT_LINUX/amd64

 1.11.10.1  13-Dec-2008  haad Update haad-dm branch to haad-dm-base2.
 1.11.6.2  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.
 1.11.6.1  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.
