Kirk McKusick 0eabe33087 Updates to UFS/FFS superblock integrity checks when reading a superblock. ... Have to add a check that the computed cylinder group size does not exceed the block size of the filesystem. It is also necessary to validate additional parameters when a superblock is going to be used in read-only mode if its supplementary information is going to be read in to ensure that the size and location of the supplementary information is valid. Also when a warning is raised let it be accepted, but bound the flagged field to the value checked by the warning. No legitimate superblocks should fail as a result of these changes.
