Shouldn't the last line read
return fchmod (dir == AT_FDCWD ? "." : dir, mode);
? Rationale: The man page [1] says
AT_EMPTY_PATH (since Linux 6.6)
If path is an empty string, operate on the file referred to
by dirfd (which may have been obtained using the open(2)
O_PATH flag). In this case, dirfd can refer to any type of
file, not just a directory. If dirfd is AT_FDCWD, the call
operates on the current working directory. This flag is
Linux-specific; define _GNU_SOURCE to obtain its
definition.
