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).

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.)

Mostly merge changes from HEAD upto 20200411

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.

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.

   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

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.

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.

Proper definitions for quotactl

Snapshot of work in progress on a modernised disk quota system:
- new quotactl syscall (versionned for backward compat), which takes
  as parameter a path to a mount point, and a prop_dictionary
  (in plistref format) describing commands and arguments.
  For each command, status and data are returned as a prop_dictionary.
  quota commands features will be added to take advantage of this,
  exporting quota data or getting quota commands as plists.

- new on disk-format storage (all 64bit wide), integrated to metadata for
  ffs (and playing nicely with wapbl).
  Quotas are enabled on a ffs filesystem via superblock flags.
  tunefs(8) can enable or disable quotas.
  On a quota-enabled filesystem, fsck_ffs(8) will track per-uid/gid
  block and inode usages, and will check and update quotas in Pass 6.
  quota usage and limits are stored in unliked files (one for users,
  one for groups)l fsck_ffs(8) will create the files if needed, or
  free them if needed. This means that after enabling or disabling
  quotas on a filesystem; a fsck_ffs(8) run is required.
  quotacheck(8) is not needed any more, on a unclean shutdown
  fsck or journal replay will take care of fixing quotas.
  newfs(8) can create a ready-to-mount quota-enabled filesystem
  (superblock flags are set and quota inodes are created).
  Other new features or semantic changes:
  - default quota datas, applied to users or groups which don't already
    have a quota entry
  - per-user/group grace time (instead of a filesystem global one)
  - 0 really means "nothing allowed at all", not "no limit".
    If you want "no limit", set the limit to UQUAD_MAX (tools will
    understand "unlimited" and "-")

  A quota file is structured as follow:
  it starts with a header, containing a few per-filesystem values,
  and the default quota limits.
  Quota entries are linked together as a simple list, each entry has a
  pointer (as an offset withing the file) to the next.
  The header has a pointer to a list of free quota entries, and
  a hash table of in-use entries. The size of the hash table depends
  on the filesystem block size (header+hash table should fit in the
  first block). The file is not sparse and is a multiple of
  filesystem block size (when the free quota entry list is empty a new
  filesystem block is allocated). quota entries to not cross
  filesystem block boundaries.

  In memory, the kernel keeps a cache of recently used quota entries
  as a reference to the block number, and offset withing the block.
  The quota entry itself is keept in the buf cache.

fsck_ffs(8), tunefs(8) and newfs(8) supports are completed (with
related atf tests :)
The kernel can update disk usage and report it via quotactl(2).

Todo: enforce quotas limits (limits are not checked by kernel yet)
      update repquota, edquota and rpc.rquotad to the new world
      implement compat_50_quotactl ioctl.
      update quotactl(2) man page

fsck_ffs required fixes so that allocating new blocks or inodes will
properly update the superblock and cg sumaries. This was not an issue up
to now because superblock and cg sumaries check happened last, but now
allocations or frees can happen in pass 6.

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.

- Retire SYCALL_MPSAFE. With the exceptions of darwin and irix emulations,
  all system calls are now MPSAFE.
- Remove unneeded acquire/release of kernel_lock.

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

Sync with HEAD.

- 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.

fix fallout from caddr_t changes.

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

- move sched_changepri back to kern_synch.c as it doesn't know PPQ anymore.

Mark MPSAFE the syscalls that are not translated (and of course, only when
the native syscall is itself marked MPSAFE).

Add missing lwp syscalls.  Put them all together into a new file,
netbsd32_lwp.c, and remove remaining traces of SA.

This still needs some MD (and possibly MI, depending on the chosen
solution) changes to actually work.

Merge newlock2 to head.

Remove support for SA. Ok core@.

- Make better use of COMPAT_XX type in syscalls.master
- Remove useless (thanks to COMPAT_XX behaviour) #ifdefs in
  syscalls.master
- Make netbsd32_compat_43.c compiled per COMPAT_LINUX32 because the latter
  needs stuff from it.

Fixes Perry's PR#34951.

Don't conditionalize *sys_ptrace.  The lack of sys_ptrace will be dealt
with differently.

Step 1 to make filehandles completely opaque to userland

do not protect the getfh syscall by
#if defined(NFS) || defined(NFSSERVER).
The native syscall also isn't.

Merge from HEAD.

Fix alignement problems for fhandle_t, exposed by gcc4.1.

While touching all vptofh/fhtovp functions, get rid of VFS_MAXFIDSIZ,
version the getfh(2) syscall and explicitly pass the size available in
the filehandle from userland.

Discussed on tech-kern, with lots of help from yamt (thanks!).

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: revisit this at another time.

support ntp_gettime again
compile tested by Havard Eidnes

Remove emulation of ntp_gettime. In preparation for "timecounters" we
will change "struct ntptimeval", so some translation would be necessary.
ntp_gettine is considered dispensable, the only userland program known
to use it is "ntptime".

- Split sys_kevent into kevent1 so that it can be used by COMPAT_NETBSD32
  code.

- To achieve COMPAT_NETBSD32 compatibility, introduce a parameter to
  kevent1 that points to functions that do the actual copyin/copyout
  operations.  This is similar to what was done in FreeBSD by Paul Saab.

- Add the COMPAT_NETBSD32 definitions and hooks.

Fix lossage I created with the 64 bit ino_t change.

64 bit inode changes.

Implement __sigtimedwait(2).

Implement the timer_create(2) family of syscalls.

Add the *xattr(2) family of syscalls.  Just like the *extattr(2) family,
they're waiting for an actual FS back-end to be tested, but are still
straightforward enough.

Add rasctl(2).  Thanks to the regression tests for that syscall, I was able
to discover the bugs in netbsd32_setitimer() and netbsd32_execve().

Add support for fsync_range(2).

Implement __clone(2).

Implement pselect(2) and pollts(2).

Add mlockall(2) and munlockall(2).

Implement the extattr(3) family of syscalls.

XXX However, those remain untested as there are currently no backend for
XXX extattr(9) in NetBSD.

Implement uuidgen(2).

track change to swapctl args in kern/syscalls.master.

o Add support for the statvfs family of syscalls (statvfs1, fstatvfs1,

o Move the statfs family out of netbsd32_fs.c and netbsd32_netbsd.c to
  netbsd_compat_20.c, compiled with COMPAT_20

Catch up to -current

In preparation for COMPAT_NETBSD32 on SH-5:

 - The MD netbsd32_machdep.h header now defines the 32-bit pointer type
   instead of using u_int32_t everywhere,
 - The MD netbsd32_machdep.h header now defines a macro (at least on
   current implementations) which converts a 32-bit pointer to its 64-bit
   equivalent,
 - Change the MI code to utilise the above two items in all the right places,
 - Implement netbsd32___sigaction_sigtramp().

Tested on Sparc64 by Matt Green.
