* syscall: update linux/loong64 kernel ABI, emulate fstatat with statxWANG Xuerui2022-05-261-16/+0
| | | | | | | | | | | | | | | | | | | | | | | | | The linux/loong64 kernel ABI has changed a little since the inception of the Go port; most notably fstat and fstatat are being removed [1], leaving only statx as the stat mechanism. Fortunately the structs are easy enough to translate, and we now exclusively use statx across the board on loong64 for best compatibility with past and future kernels (due to the architecture's young age, statx is always available). In wiring up the statx calls, it turned out the linux/loong64 syscall definitions were out-of-date, so the generation script received some tweaking as well.

* all: go fix -fix=buildtag std cmd (except for bootstrap deps, vendor)Russ Cox2021-10-281-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | When these packages are released as part of Go 1.18, Go 1.16 will no longer be supported, so we can remove the +build tags in these files. Ran go fix -fix=buildtag std cmd and then reverted the bootstrapDirs as defined in src/cmd/dist/buildtool.go, which need to continue to build with Go 1.4 for now. Also reverted src/vendor and src/cmd/vendor, which will need to be updated in their own repos first. Manual changes in runtime/pprof/mprof_test.go to adjust line numbers. For #41184.

* internal/syscall/unix: use libc calls on DarwinKeith Randall2018-11-081-1/+1
| | | | | | | | | Add unexported unlinkat, openat, and fstatat calls, so that the internal/syscall/unix package can use them. Change-Id: I1df81ecae6427211dd392ec68c9f020fe131a526 Reviewed-on: https://go-review.googlesource.com/c/148457 Reviewed-by: Brad Fitzpatrick <bradfitz@golang.org>
* os: add support for long path names on freebsd RemoveAllTobias Klauser2018-11-011-1/+1
| | | | | | | | | | | | | | | | | | | Follow CL 146020 and enable RemoveAll based on Unlinkat and Openat on freebsd. Since the layout of syscall.Stat_t changes in FreeBSD 12, Fstatat needs a compatibility wrapper akin to Fstatat in x/sys/unix. See CL 138595 and CL 136816 for details.

* os: add support for long path names on unix RemoveAllOliver Stenbom2018-10-311-0/+58
| | | | | | | | | | | | | | | | | | | | | | | | | On unix systems, long enough path names will fail when performing syscalls like `Lstat`. The current RemoveAll uses several of these syscalls, and so will fail for long paths. This can be risky, as it can let users "hide" files from the system or otherwise make long enough paths for programs to fail. By using `Unlinkat` and `Openat` syscalls instead, RemoveAll is safer on unix systems. Initially implemented for linux, darwin, dragonfly, netbsd and openbsd. Not yet implemented on freebsd due to fstatat 64-bit inode compatibility issues.
