As of now all filenames known by UBIFS are strings with a NUL terminator. With encrypted filenames a filename can be any binary string and the r5 function cannot search for the NUL terminator. UBIFS always knows how long a filename is, therefore we can change the hash function to iterate over the filename length to work correctly with binary strings.
