Squashfs: add sanity checks to fragment reading at mount time Fsfuzzer generates corrupted filesystems which throw a warn_on in kmalloc. One of these is due to a corrupted superblock fragments field. Fix this by checking that the number of bytes to be read (and allocated) does not extend into the next filesystem structure. Also add a couple of other sanity checks of the mount-time fragment table structures. Signed-off-by: Phillip Lougher <phillip@lougher.demon.co.uk>
