Linux GSoC-2024: renameat2, clone3, sync_file_range, syncfs (Shivraj Jamgade)

Add linux POSIX message queue support (Ricardo Branco)

From gsoc 2024: Implement faccessat2 and getcpu (Shivraz)

Add inotify* syscalls GSoC 2023 (Theodore Preduta)

Add linux waitid(2) from GSoC 2023 (Theodore Preduta)

Add/fix statx, readahead, close_range. From GSoC 2023 by Theodore Preduta

add epoll syscalls

add prlimit64(2) syscall to COMPAT_LINUX and COMPAT_LINUX32

add getrandom(2) syscall entry

Add preadv(2) and pwritev(2) system calls to COMPAT_LINUX and COMPAT_LINUX32.

Add the eventfd system calls to COMPAT_LINUX and COMPAT_LINUX32.

Add the timerfd syscalls to COMPAT_LINUX and COMPAT_LINUX32.

Add the POSIX timer syscalls (timer_create(), timer_settime(), timer_gettime(),
timer_getoverrun(), and timer_delete()) to COMPAT_LINUX and COMPAT_LINUX32.

Add suppport for Linux preadv(2) and pwritev(2).  Same as native, except
for the silly way that the offset argument is passed in.

Add Linux eventfd, timerfd, and POSIX timer calls.

Add a NetBSD native futex implementation, mostly written by riastradh@.
Map the COMPAT_LINUX futex calls to the native ones.

Mostly merge changes from HEAD upto 20200411

add dummy implementation of linux fallocate() which just returns EOPNOTSUPP;
this is needed so that glibc falls back to emulation and apps behaving
properly, since EOPNOTSUPP is a documented and expected return code, but
ENOSYS is not

right now there are no filesystems in NetBSD tree supporting the fallocate
VOP, so no point trying to map this to a native call

many changes for COMPAT_LINUX:
 - update the linux syscall table for each platform.
 - support new-style (NPTL) linux pthreads on all platforms.
   clone() with CLONE_THREAD uses 1 process with many LWPs
   instead of separate processes.
 - move the contents of sys__lwp_setprivate() into a new
   lwp_setprivate() and use that everywhere.
 - update linux_release[] and linux32_release[] to "2.6.18".
 - adjust placement of emul fork/exec/exit hooks as needed
   and adjust other emul code to match.
 - convert all struct emul definitions to use named initializers.
 - change the pid allocator to allow multiple pids to refer to the same proc.
 - remove a few fields from struct proc that are no longer needed.
 - disable the non-functional "vdso" code in linux32/amd64,
   glibc works fine without it.
 - fix a race in the futex code where we could miss a wakeup after
   a requeue operation.
 - redo futex locking to be a little more efficient.

Update some syscalls/arguments to use the new compat50 equivalents.

Convert the syscalls.master to a format from which it is easier
to parse and generate the compat name and basename (e.g. __stat50
and stat).  Use this to autogenerate __RENAME()'s to the rump_syscalls
header so that they can be called e.g. rump_sys_socket() instead
of rump_sys___socket30().

Fix nanosleep(2) on 64-bit archs. Do not call native nanosleep
syscall, but rather a modified version the will take care of `struct
timespec' conversions.

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

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.

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.

compat linux (and linux32) uid16 functions cleanup and fixes.

- Move uid16 functions to their own file linux_uid16.c, included by
  needed archs (arm, i386 and m68k).
- Add new MI types linux_{u,g}id16_t.
- Add macros to handle linux_uid16_t and uid_t conversions.
- Add linux_sys_getres{uid,gid}16 syscalls, to fix an overflow with
  bad sizes given to copyout when linux_sys_getres{uid,gid} are used.
- Update arm syscall table to use more uid16 functions.

  syscall.

ok by christos and 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.

add stub entries for syscalls added until Linux kernel 2.6.7

move the ARM-specific syscall range up to offset 0x180, to make room
for the new syscalls

connect madvise(2) and mincore(2) - apparently the newer Linux libs
don't stub it anymore, so allow the application to take advantage
of them

the Linux calls appear to be compatible in the flag values and semantics,
so a wrapper is not necessary

add Linux compat arg wrapper for ftruncate64(), and change linux compat

Problem found and patch supplied in PR kern/22360 by Ales Krenek
This is the last of syscalls with hidden 'pad' arg we didn't have
wrapper for; all the others (lseek, mmap, pwrite, pread) already had
wrapper before.

getrlimit and setrlimit now have Linux-specific implementations.  Use them.

- add a real linux_sys___sysctl because the mib numbers are different.
  implement only the kernel version getting entries.
- make the signal conversion functions consistent; dest is arg 1.
- make linux_fakedev deal with block and char devices differently.
- add linux_sys_ugetrlimit, and flesh out the regular get/setrlimit so
  that they work properly.
- add linux_mmap2 [untested].
- bump kernel to 2.4.18, and make the date be valentine's day :-)
- linux_sys_*stat64 family was totally busted. Fix it.

tested only on i386.

Status:
	gdb, telnet, work
	jdk-1.4.0 extractor works, jdk still coredumps.

Add support for breakpoints to ARMLinux emulation.

Make syscall 0 an explicit call of linux_sys_nosys, as it is on i386.  This
is necessary to get a prototype for linux_sys_nosys generated in syscallargs.h.

Syscall 0 isn't syscall() on ARMLinux.  Mark it UNIMPL instead.

Add support for the ARM-specific syscalls in ARMLinux.  These are invoked
by SWI numbers above 0x9f0000, but we re-map them down to somewhere just
after the end of the usual syscall range, since NetBSD doesn't handle
sparse syscall arrays well.

The only syscall I've actually implemented in this range is cacheflush(),
which was previously being mapped to fork(), causing ... interesting results.

Shuffle uname calls around.  It turns out we don't use the same names as
Linux does, so:
sys_olduname -> linux_sys_oldolduname
sys_uname    -> linux_sys_olduname
sys_newuname -> linux_sys_uname

Crude first cut at ARMLinux binary compatibility.  Successfully runs
"/emul/linux/bin/echo hello, world", dynamically linked.
