2022-09-01syscall: Faccessat: use faccessat2 on linuxKir Kolyshkin
Linux kernel 5.8 added the faccessat2 syscall taking a flags argument. Attempt to use it in Faccessat and fall back to the existing implementation mimicking glibc faccessat. Do not export the new syscall value so we keep syscall API intact. Part of this commit is generated by: GOOS=linux ./mkall.sh -syscalls zsyscall_linux_*.go This is similar to [1] amended by [2].

2022-08-18syscall: implement EpollCreate using EpollCreate1 on all linux platformsTobias Klauser
Most newer architectures (e.g. arm64, riscv64, loong64) don't provide the epoll_create syscall. Some systems (e.g. Android) block it even if it were available. In the kernel, the epoll_create syscall is implemented [1] the same way EpollCreate is implemented in this package for platforms without the epoll_create syscall. The epoll_create1 syscall is available since Linux kernel 2.6.27 and the minimum required kernel version is 2.6.32 since Go 1.18 (see #45964). Thus, avoid the separate wrapper and consistently implement EpollCreate using EpollCreate1. [1] https://elixir.bootlin.com/linux/v5.15-rc1/source/fs/eventpoll.c#L2006 The same change was already done in CL 349809 for golang.org/x/sys/unix.

Most architectures currently already implement Pipe using the pipe2 syscall. Only 386, amd64 and mips{,le} still use the pipe syscall.

2020-10-23syscall: support POSIX semantics for Linux syscallsAndrew G. Morgan
This change adds two new methods for invoking system calls under Linux: syscall.AllThreadsSyscall() and syscall.AllThreadsSyscall6(). These system call wrappers ensure that all OSThreads mirror a common system call. The wrappers serialize execution of the runtime to ensure no race conditions where any Go code observes a non-atomic OS state change. As such, the syscalls have higher runtime overhead than regular system calls, and only need to be used where such thread (or 'm' in the parlance of the runtime sources) consistency is required. The new support is used to enable these functions under Linux: syscall.Setegid(), syscall.Seteuid(), syscall.Setgroups(), syscall.Setgid(), syscall.Setregid(), syscall.Setreuid(), syscall.Setresgid(), syscall.Setresuid() and syscall.Setuid(). They work identically to their glibc counterparts. Extensive discussion of the background issue addressed in this patch can be found here: https://github.com/golang/go/issues/1435 In the case where cgo is used, the C runtime can launch pthreads that are not managed by the Go runtime. As such, the added syscall.AllThreadsSyscall*() return ENOTSUP when cgo is enabled. However, for the 9 syscall.Set*() functions listed above, when cgo is active, these functions redirect to invoke their C.set*() equivalents in glibc, which wraps the raw system calls with a nptl:setxid fixup mechanism. This achieves POSIX semantics for these functions in the combined Go and C runtime. As a side note, the glibc/nptl:setxid support (2019-11-30) does not extend to all security related system calls under Linux so using native Go (CGO_ENABLED=0) and these AllThreadsSyscall*()s, where needed, will yield more well defined/consistent behavior over all threads of a Go program. That is, using the syscall.AllThreadsSyscall*() wrappers for things like setting state through SYS_PRCTL and SYS_CAPSET etc. Fixes #1435 Change-Id: Ib1a3e16b9180f64223196a32fc0f9dce14d9105c Reviewed-on: https://go-review.googlesource.com/c/go/+/210639 Trust: Emmanuel Odeke <emm.odeke@gmail.com> Trust: Ian Lance Taylor <iant@golang.org> Trust: Michael Pratt <mpratt@google.com> Run-TryBot: Emmanuel Odeke <emm.odeke@gmail.com> Reviewed-by: Michael Pratt <mpratt@google.com> Reviewed-by: Austin Clements <austin@google.com>

2018-07-27syscall: support Faccessat flags argumentIan Lance Taylor
The Linux kernel faccessat system call does not take a flags parameter. The flag parameter to the C library faccessat function is implemented in C. The syscall.Faccessat function takes a flags parameter. In older releases we have passed the flags parameter to the kernel, which ignored it. In CL 120015 we started returning an error if any flags were set. That seems clearly better than ignoring them, but it turns out that some code was using the flags. The code was previously subtly broken. Now it is obviously broken. That is better, but we can do better still: we can implement the flags as the C library does. That is what this CL does.

While making changes, I discovered that nacl syscall.Exit returned error func Exit(code int) (err error) and I changed it into func Exit(code int) like all other OSes.

This avoids hanging when a Go program uses a FUSE filesystem and the dup system call has to close a file descriptor. When dup uses RawSyscall then the goroutine calling dup will occupy a scheduler slot (a p structure) during the call, and may block waiting for some other goroutine to respond to the close call on the FUSE filesystem. Changing to Syscall avoids the problem. This makes Dup a tiny bit slower but is quite unlikely to make a difference for any real programs. Fixes #10202.

For platforms where pipe2(2) is not supported in the minimum 2.6.23 kernel, amd64 and 386, we retain pipe(2). For all other platforms pipe(2) is removed and Pipe forwards to pipe2(2). Because mksycall.pl does not sort symbols before generating the output file the diff includes some unavoidable code moves as Pipe and Pipe2 are processed latter in the run.
