Theodore Ts'o 3995881b0f ext4: fix in-superblock mount options processing ... commit 5aee0f8a3f42c94c5012f1673420aee96315925a upstream. Fix a large number of problems with how we handle mount options in the superblock. For one, if the string in the superblock is long enough that it is not null terminated, we could run off the end of the string and try to interpret superblocks fields as characters. It's unlikely this will cause a security problem, but it could result in an invalid parse. Also, parse_options is destructive to the string, so in some cases if there is a comma-separated string, it would be modified in the superblock. (Fortunately it only happens on file systems with a 1k block size.)
