chmod: -L option fails to traverse symlinks #7023
Description
Environment: uutils main branch (git commit dddbc17), gnu coreutils version 9.5.218-7e5b6
Steps to reproduce:
# Create a file at `a/b/file` and a link to it at `a/c/link`.
mkdir -p a/b a/c
touch a/b/file
ln -s ../b/file a/c/link
# Explicitly set the permissions to start from.
chmod =777 a/b a/c a/b/file
# Set the new permissions.
chmod 755 -L -R a/c
What happens now: with uutils chmod, the permissions of the target of the symbolic link have not been changed:
$ ls -ld a/b/file
-rwxrwxrwx 1 jeffrey jeffrey 0 Dec 29 14:32 a/b/file
What I expected to happen: in GNU chmod, the permissions of the target are changed:
$ ls -ld a/b/file
-rwxr-xr-x 1 jeffrey jeffrey 0 Dec 29 14:32 a/b/file
Notes: this is causing a failure in the tests/chmod/symlinks.sh file in the GNU test suite.
