io: Add FUSE-based test for fchmod

2024-09-09T07:51:50Z

Test all mode arguments, and that extra bits are ignored as required by POSIX. Reviewed-by: DJ Delorie

io: Add tst-lstat-nofollow, tst-lstat-nofollow-time64

2024-09-09T07:14:22Z

They verify that lstat, lstat64 do not follow symbolic links. Reviewed-by: DJ Delorie

io: Fix destructive nature of tst-fchmod-errors

We must not change the permissions of /dev/null if running as root. Reviewed-by: Carlos O'Donell

io: Add error tests for fchmod

2024-08-30T19:12:01Z

On Linux most descriptors that do not correspond to file system entities (such as anonymous pipes and sockets) have file permissions that can be changed. While it is possible to create a custom file system that returns (say) EINVAL for an fchmod attempt, testing this does not appear to be useful. Reviewed-by: Carlos O'Donell

Test mkdirat use of mode argument

2024-08-22T11:25:14Z

The test io/tst-mkdirat doesn't verify the permissions on the created directory (thus, doesn't verify at all anything about how mkdirat uses the mode argument). Add checks of this to the existing test. Tested for x86_64.

support: Use macros for *stat wrappers

2024-08-16T14:05:20Z

Macros will automatically use the correct types, without having to fiddle with internal glibc macros. It's also impossible to get the types wrong due to aliasing because support_check_stat_fd and support_check_stat_path do not depend on the struct stat* types. The changes reveal some inconsistencies in tests. Reviewed-by: Adhemerval Zanella

io: Use struct statx and xstatx in tests

2024-08-16T14:05:20Z

This avoids the need to define struct_statx to an appropriate struct stat type variant because struct statx does not change based on time/file offset flags. Reviewed-by: Adhemerval Zanella

Add STATX_SUBVOL from Linux 6.10 to bits/statx-generic.h

debug: Fix clang open fortify wrapper (BZ 31927)

2024-07-02T13:19:44Z

The clang open fortify wrapper from 4228baef1a94e8bde84ad74 added a restriction where open with 3 arguments where flags do not contain O_CREAT or O_TMPFILE are handled as invalid. They are not invalid, since the third argument is ignored, and the gcc wrapper also allows it. Checked x86_64-linux-gnu and with a yocto build for some affected packages. Tested-by: “Khem Raj ”

debug: Fix clang open fortify wrapper (BZ 31927)

2024-06-27T16:32:48Z

The fcntl.h fortify wrapper for clang added by 86889e22db329abac61 missed the __fortify_clang_overload_arg and and also added the mode argument for the __fortify_function_error_function function, which leads clang to be able to correct resolve which overloaded function it should emit. Checked on x86_64-linux-gnu. Reported-by: Khem Raj Tested-by: Khem Raj
