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. ---------------------------------------------------------------- Dan Carpenter (1): Squashfs: sanity check information from disk Manish Sharma (1): Squashfs: Optimized uncompressed buffer loop Phillip Lougher (5): Squashfs: fix corruption check in get_dir_index_using_name() Squashfs: fix corruption checks in squashfs_lookup() Squashfs: fix corruption checks in squashfs_readdir() Squashfs: add corruption check in get_dir_index_using_offset() Squashfs: add corruption check for type in squashfs_readdir() fs/squashfs/block.c | 11 ++++------- fs/squashfs/dir.c | 17 +++++++++++++---- fs/squashfs/namei.c | 8 ++++++-- fs/squashfs/squashfs_fs.h | 5 ++++- 4 files changed, 27 insertions(+), 14 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
