Unlike the types it replaces, the "internal/unsafeheader" package has a regression test to ensure that its header types remain equivalent to the declarations provided by the "reflect" package. Since "internal/unsafeheader" has almost no dependencies, it can be used in other low-level packages such as "syscall" and "reflect". This change is based on the corresponding x/sys change in CL 231177.

For example, errors.Is(err, os.ErrPermission) is equivalent to os.IsPermission(err) with added unwrapping support. Move the definition for os.ErrPermission and others into the syscall package. Add an Is method to syscall.Errno and others. Add an Unwrap method to os.PathError and others.

* syscall: add AIX operating systemClément Chigot2018-10-101-1/+1
| | | | | | | | | | | | | | | This commit adds AIX operating system to syscall package for ppc64 architecture. It also adds the file syscall_aix.go in the runtime package for syscalls needed during fork and exec.

* syscall: support Getwd on all BSDsTobias Klauser2018-02-131-0/+10
| | | | | | | | | | | | | | | | | | | | | All supported BSDs provide the SYS___GETCWD syscall which can be used to implement syscall.Getwd. With this change os.Getwd can use a single syscall instead of falling back to the current kludge solution on the BSDs. This doesn't add any new exported functions to the frozen syscall package, only ImplementsGetwd changes to true for dragonfly, freebsd, netbsd and openbsd. As suggested by Ian, this follows CL 83755 which did the same for golang.org/x/sys/unix. Also, an entry for netbsd/arm is added to mkall.sh which was used to generate the syscall wrappers there.

* syscall: fix Send{msg,msgN}, Recvmsg and control message handling on solarisMikio Hara2016-10-031-0/+1
| | | | | | | | | | | | | | | | | | This change switches the use of socket implementation from the conventional SUS-based one to the latest POSIX-based one to make socket control message work correctly on Solaris. It looks like those two implementations, Socket over TLI/XTI and Socket, have different semantics in details but it wouldn't hurt the existing applications because the exposed syscall API doesn't support socket properties related to such a protocol independent application framework. Fixes #7402. Change-Id: I45a4e782d606bfbebe1404086c50a8c69af53461 Reviewed-on: https://go-review.googlesource.com/30171 Reviewed-by: Ian Lance Taylor <iant@golang.org>
