      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.

      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.

      unix: add support for linux/riscv64 · 8cf3aee4
      Tobias Klauser authored 
      Add syscall wrappers, error constants and types for linux/riscv64

Switch docker image to Ubuntu 18.10 in order to get qemu supporting
riscv64. Also set the uname release string for qemu to 4.15 (the first
Linux kernel version with riscv64 support), because otherwise running
the generating C program in mkerrors.sh on a host with an older kernel
would fail with a "FATAL: kernel too old".

Note that linux/riscv64 is currently only usable using gccgo.

Updates golang/go#27532
