Phillip Lougher 4b0180a49f Squashfs: add mount time sanity check for block_size and block_log match ... Squashfs currently has a sanity check for block_size less than or equal to the maximum block_size (1 Mbyte). This catches some superblock corruption, but obviously with a block_size maximum of 1 Mbyte there's 7 correct values (4K, 8K, 16K, 32K, ... etc) and a lot of incorrect values which are not caught by this check. The Squashfs superblock, however, has both a block_size and a block_log (2^block_log == block_size). Checking that the block_size matches the block_log is a much more robust check. Corruption of the superblock is unlikely to produce values which match, and it also ensures the block_size is an exact power of two.
