      unix: add IoctlSetPointerInt · 0cf1ed9e
      David Anderson authored 
      IoctlSetPointerInt is necessary for interacting with the PPP kernel
driver, which wants it passed as a pointer to int, rather than the
more conventional int cast as a pointer.

We can technically do this already with
IoctlSetInt(int(uintptr(unsafe.Pointer(&foo)))), but that's just
masking the operation we're trying to execute in the first place,
and relying on the internals of IoctlSetInt to do the right
inverse transformation.

      unix: FreeBSD 12 ino64 support · 5535b4e6
      Yuval Pavel Zholkover authored 
      Background:
The 64-bit inode project was merged into the upcoming FreeBSD 12 release.
It changes the ABI for structs holding inodes: stat, statfs, dirent.
New system call numbers were introduced which accept the new struct layouts,
the old ones were marked as COMPAT11.
Their equivalent libc wrappers are using ELF symbol versioning.
The new wrappers have moved from @FBSD_1.0 to @FBSD_1.5.

Backward and forward compatability is achieved by always using the new struct
layouts while converting the old struct instance to the new layout on old kernels.
https://svnweb.freebsd.org/base?view=revision&revision=318736
https://svnweb.freebsd.org/base?view=revision&revision=320278

The same approach is used for Go:
The new Stat_t, Statfs_t and Dirent types hold 64-bit inodes and additional ABI
changes, they are generated from their C definitions in FreeBSD-12 using cgo -godefs.
Each type has an unexported *_freebsd11 counterpart generated the same way.
Previous directly exposed syscalls like Fstat have now a wrapper in place calling
either fstat or fstat_freebsd12 zsyscall wrapper based on the kern.osreldate.
If an old syscall needs to be used, then the returned *_freebsd11 result is converted
to the new layout before returning from the wrapper.

Introduce supportsABI() call to check the kern.osreldate sysctl for the ABI version.
Drop the old struct stat8 definition in favour of the <sys/stat.h> version.
Run the mktypes part of GOOS=freebsd GOARCH={386,amd64,arm} ./mkall.sh
on FreeBSD-12.0-ALPHA6 (r338675), updating all types except Kevent.

Expose Mknodat, both COMPAT11 version (currently missing) and the FreeBSD 12 one.
Some COMPAT11 syscalls have no direct FreeBSD 12 counterpart, in those cases
an *at(AT_FDCWD, ...) is used instead.

Updates golang/go#22448

      unix: add SOF_TIMESTAMPING_* flags on Linux · 8e24a49d
      Tobias Klauser authored 
      Add the SOF_TIMESTAMPING_* flags used to request different types of
timestamping operations. In

  err := unix.SetsockoptInt(fd, unix.SOL_SOCKET, unix.SO_TIMESTAMPING, val)

val is a mask of SOF_TIMESTAMPING_* values.

See https://www.kernel.org/doc/Documentation/networking/timestamping.txt
for more information.

Fixes golang/go#28173

      unix: add support for aix/ppc64, gc implementation · 8f1d3d21
      chigotc authored 
      This commit ports unix package for aix/ppc64 with gc implementation.

In order to merge as much as possible gc and gccgo implementation, the
mksyscall_aix_ppc64.pl creates three files.

zsyscall_aix_ppc64.go is common for both implementation. It has the main
syscall function and handles the pointer creations, type conversions
and the error if needed. It calls a function "call..." which is
available for each implementation.

zsyscall_aix_ppc64_gc.go is the gc part. It implements "call..."
functions using //go:cgo_import_dynamic and //go:linkname. It is
based on syscall.syscall6 function.

zsyscall_aix_ppc64_gccgo.go is the gccgo part. It implements "call..."
functions using cgo and C functions.

Some unavailable syscalls were also removed from the previous
implementation.

For aix/ppc, the script is left unchanged as aix/ppc won't be
implemented inside gc.
