squashfs-tools-ng.git/include, branch v0.6.1 A new set of tools and libraries for working with SquashFS images https://git.infraroot.at/squashfs-tools-ng.git/atom?h=v0.6.1 2019-08-23T10:10:16+00:00 Do bounds checking in metadata reader 2019-08-23T10:10:16+00:00 David Oberhollenzer david.oberhollenzer@sigma-star.at 2019-08-23T10:10:16+00:00 urn:sha1:029a8db2701afb0653c6e789c878bb768ceb87e1 In all cases where metadata blocks are read, we can roughly (in some cases even preciesly) say in what range those metadata blocks will be, so it makes sense to throw an error if an attempt is made to wander outside this range. Furthermore, when reading from an uncompressed block, it is more reasonable to check against the actual block bounds than to padd it with 0 bytes.

This also makes zlib a hard dependency which also means the whole "do we have a compressor" sanity check in the build system can be removed.

Also the deduplication code no longer needs to worry about order, since the file being deduplicated is only added after deduplication is done.

The underlying implementation is currently still synchronuous. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
