Implement as wrapper around sys_faccessat(). Latest dash started using it, also define AT_EACCESS: usr/dash/bltin/test.c: In function ?test_file_access?: usr/dash/bltin/test.c:490: error: too many arguments to function ?faccessat?

patch is also available in current patch queue: git pull git://git.debian.org/users/maks/klibc.git maks Run it on latest dash and it could still test readable files as readable.

3-arg faccessat is unfortunately an incomplete implementation. It does not match user-space needs, for example due to wrong answer when egid != gid. dash started to detect klibc faccessat() syscall wrapper.

For historical reasons, POSIX unfortunately also allows access() and faccessat() to return success for X_OK if the current process is privileged, even when the above condition is not fulfilled and actual execution would fail.

Hello, Here is V2 of the arm64 support for klibc patch set. Notable changes since the original series: * fp regs dropped from setjmp/longjmp * chmod, lstat and stat re-implemented with *at functions. * open64 merged into open. As with the original, this series is to be applied against the latest klibc, just after 25a66fa README.klibc: update build information V2 has been tested on x86_64

Hello, This series introduces arm64 support to klibc. I've rebased the work from Neil Williams and Anil Singhar into the following three patches. Most of the code changes are due to new syscall implementations being needed for arm64 as a only a minimal set of syscalls are defined in the arm64 kernel. This series is to be applied against the latest klibc, just after 25a66fa README.klibc:
