   Squashfs: add corruption check for type in squashfs_readdir() (2013-09-06 04:57:54 +0100)

----------------------------------------------------------------
A couple of minor additional sanity check patches for corrupted information,
and some fixes.  Apart from that there's a minor loop optimisation.

These sanity checks mainly exist to trap maliciously corrupted
filesystems either through using a deliberately modified mksquashfs,
or where the user has deliberately chosen to generate uncompressed
metadata and then corrupted it.

Normally metadata in Squashfs filesystems is compressed, which means
corruption (either accidental or malicious) is detected when
trying to decompress the metadata.  So corrupted data does not normally
get as far as the code paths in question here.
