PR 59352: add netbsd32 compat for semtimedop(2)

branches: 1.146.2;
Rename dup3110 to dup3100 to match historical practice for NetBSD-11,
because we already have kevent100. Fix compat_dup3 to belong in compat_100
not compat_110.

version dup3

COMPAT_NETBSD32: Add support for epoll(2).

COMPAT_NETBSD32: Add support for memfd_create(2).

COMPAT_NETBSD32: Catch up with sys___kevent100() addition.

XXX
Add epoll_* and memfd_create.

Add the eventfd(2) system call to COMPAT_NETBSD32.

Add timerfd system calls to COMPAT_NETBSD32.

Teach about getrandom(2) to COMPAT_NETBSD32.

Add ACL support for FFS. From FreeBSD.

Mirror the change made to native -- move futex calls to 166-168.

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

Remove _lwp_gettid(2) system call. This problem is going to be solved
another way. (Note: this call was never exposed in libc, so we can just
recycle the syscall number.)

branches: 1.134.2;
Add support for lazily generating a "global thread ID" for a LWP. This
identifier uniquely identifies an LWP across the entire system, and will
be used in future improvements in user-space synchronization primitives.

(Test disabled and libc stub not included intentionally so as to avoid
multiple libc version bumps.)

Split out the quota code from the rest of compat_netbsd32 module. This
allows loading of compat_netbsd32 on kernels that don't have ``options
QUOTA'' enabled.

Properly mark netbsd32_compat_43 syscalls that are directly implemented
by calling their compat_43 equivalents. With these changes, and with
built-in versions of COMPAT_NETBSD32, COMPAT_NOMID, and COMPAT_09, I can
now run a netbsd-0.9 statically linked i386 (32-bit) version of /bin/ls
on a 9.99.x amd64 host!

Addresses PR kern/55047 but more changes coming to handle non-built-in
modules.

XXX pullup-9

Catch up after getpid/getgid/getuid changes in native ABI in 2008

getpid(), getuid() and getgid() used to call respectively sys_getpid(),
sys_getuid() and sys_getgid(). In the BSD4.3 compat mode there was a
fallback to call sys_getpid_with_ppid() and related functions.

In 2008 the compat ifdef was removed in sys/kern/syscalls.master r. 1.216.

For purity reasons we probably shall restore the NetBSD original behavior
and implement BSD4.3 one as a compat module, however it is not worth the
complexity.

Align the netbsd32 compat ABI to native ABI and call functions that return
two integers as in BSD4.3.

branches: 1.130.2;
netbsd32_size_t should be used instead of size_t for argument of
32-bit syscalls:

- netbsd32___getvfsstat90: bufsize
- netbsd32___fhstatvfs190: fh_size

No need to pullup, since these syscalls were introduced after
branch of netbsd-9.

For netbsd32_readlinkat(2), bufsize is netbsd_size_t, not size_t.
Since bufsize is the last argument, this affects only LP64EB.

XXX
pullup to netbsd-9, -8, and -7

Merge the [pgoyette-compat] branch

move mmap(), compat 40 mount(), pipe() and getfh() into their own files
as the implementation is non trivial or is compat. mark old mount()
properly instead of manually #if'ing ito to ENOSYS.

Add getsockopt2().

Remove the kernel PMC code. Sent yesterday on tech-kern@.

This change:

* Removes "options PERFCTRS", the associated includes, and the associated
ifdefs. In doing so, it removes several XXXSMPs in the MI code, which is
good.

* Removes the PMC code of ARM XSCALE.

* Removes all the pmc.h files. They were all empty, except for ARM XSCALE.

* Reorders the x86 PMC code not to rely on the legacy pmc.h file. The
definitions are put in sysarch.h.

* Removes the kern/sys_pmc.c file, and along with it, the sys_pmc_control
and sys_pmc_get_info syscalls. They are marked as OBSOL in kern,
netbsd32 and rump.

* Removes the pmc_evid_t and pmc_ctr_t types.

* Removes all the associated man pages. The sets are marked as obsolete.

Revert vadvise(2) removal

This system call was used in legacy Lisp code, that was inherited to modern
age and still compiled against supported compat layers (e.g. in clisp,
oaklisp, Franz Lisp).

It used to instruct the kernel about paging policy (G/C aware, flush etc).

Newly compiled code (assuming that it will detect vadvise()) will use the
libc stub for vadvise(). The headers for this interface are gone.

vadvise(2) could be marked as COMPAT_80, but as long as we support ultrix,
sunos or aout68k ABI, don't bother with this.

Continuation of work on PR kern/50489

Mark the nfssvc syscall as auto-loadable from the compat_netbsd32_nfssrv
module (to be committed shortly).

Don't reference netbsd32_nfssvc unless NFSSERVER is defined.
Fixes PR 49994.

add netbsd32 support for nfssvc(2). we do this by defining 5 copyin/out
functions that do all the ugly work, are just plain copyin/out for the
native system calls, and do the necessary translations for netbsd32.

with this i'm able to run 32 bit nfsd and mountd on 64 bit kernel and

better error reporting

diagnostics flag

- update copy of syscall table in gdb ppc sources

Kill fs_nfs.h and #ifdef NFS by making getfh() support unconditional

also doubt that it would work anymore with all the changes to fs
exporting etc).

-fs_lfs.h

Remove lfs syscall support from compat. I can't really imagine
anyone wanting to run lfs megamaid as a e.g. FreeBSD binary.
Besides, the real action has been in fcntl() for >5 years now.

of rump_sys___socket30().

Changes to make ktrace LKM friendly and reduce ifdef KTRACE. Proposed
on tech-kern.

- Fix a bug with _lwp_park() where if the computed wakeup time was under
1 microsecond into the future, the thread could enter an untimed sleep.
- Change the signature of _lwp_park() to accept an lwpid_t and second
hint pointer, but do so in a way that remains compatible with older
pthread libraries. This can be used to wake another thread before the
calling thread goes asleep, saving at least one syscall + involuntary
context switch. This turns out to be a fairly large win on the condvar
benchmarks that I have tried.
- Mark some more syscalls MP safe.

Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.

the native syscall is itself marked MPSAFE).

Add missing lwp syscalls. Put them all together into a new file,
