2011-12-30Squashfs: optimise squashfs_cache_get entry searchAjeet Yadav1-3/+8
squashfs_cache_get() iterates over all entries to search for block its looking for. Often get() / put() are called for same block. If we cache the current entry index, then we can optimise the subsequent *_get() calls. Signed-off-by: Ajeet Yadav <ajeet.yadav.77@gmail.com> Signed-off-by: Phillip Lougher <phillip@squashfs.org.uk>

2011-01-13Squashfs: move squashfs_i() definition from squashfs.hPhillip Lougher1-1/+0
Move squashfs_i() definition out of squashfs.h, this eliminates the need to #include squashfs_fs_i.h from numerous files. Signed-off-by: Phillip Lougher <phillip@lougher.demon.co.uk>
2010-01-20Squashfs: factor out remaining zlib dependencies into separate wrapper filePhillip Lougher1-1/+0
Move zlib buffer init/destroy code into separate wrapper file. Also make zlib z_stream field a void * removing the need to include zlib.h for most files. Signed-off-by: Phillip Lougher <phillip@lougher.demon.co.uk>
2009-05-13Squashfs: fix breakage when page size > metadata block sizeDoug Chapman1-0/+1
Squashfs is broken on any system where the page size is larger than the metadata size (8192). This is easily fixed by ensuring cache->pages is always > 0.

2009-03-05Squashfs: Fix oops when reading fsfuzzer corrupted filesystemsPhillip Lougher1-2/+2
This fixes a code regression caused by the recent mainlining changes. The recent code changes call zlib_inflate repeatedly, decompressing into separate 4K buffers, this code didn't check for the possibility that zlib_inflate might ask for too many buffers when decompressing corrupted data.
