Miklos Szeredi c7f5567b5d ovl: fix encoding fid for lower only root ... commit 004b8d1491 upstream. ovl_check_encode_origin() should return a positive number if the lower dentry is to be encoded, zero otherwise. If there's no upper layer at all (read-only overlay), then it obviously needs to return positive. This was broken by commit 16aac5ad1f ("ovl: support encoding non-decodable file handles"), which didn't take the lower-only configuration into account. Fix by checking the no-upper-layer case up-front. Reported-and-tested-by: Youzhong Yang <youzhong@gmail.com> Closes: https://lore.kernel.org/all/CADpNCvaBimi+zCYfRJHvCOhMih8OU0rmZkwLuh24MKKroRuT8Q@mail.gmail.com/ Fixes: 16aac5ad1f ("ovl: support encoding non-decodable file handles") Cc: <stable@vger.kernel.org> # v6.6 Signed-off-by: Miklos Szeredi <mszeredi@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		2024-06-27 13:52:28 +02:00
