If the ext3 journal gets out of sync with what is written on disk, for example because of an unexpected power cut, ext4fs_read_file can return an all-zero directory entry. In that case, ext4fs_iterate_dir would infinite loop. This patch detects when a directory entry's direntlen member is 0 and returns a failure status, which breaks out of the infinite loop. As a result, U-Boot will not find files that may subsequently be recovered when the journal is replayed. This is better behaviour than hanging in an infinite loop, but as a further improvement maybe U-Boot could interpret the ext3 journal and actually find the unsynced entries.
