2011-02-28Squashfs: extend decompressor framework to handle compression optionsPhillip Lougher1-2/+2
Extend decompressor framework to handle compression options stored in the filesystem. These options can be used by the relevant decompressor at initialisation time to over-ride defaults. The presence of compression options in the filesystem is indicated by the COMP_OPT filesystem flag. If present the data is read from the filesystem and passed to the decompressor init function. The decompressor init function signature has been extended to take this data. Also update the init function signature in the glib, lzo and xz decompressor wrappers.

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>
2010-08-05Squashfs: fix block size use in LZO decompressorPhillip Lougher1-3/+5
Sizing the buffer using block size alone is incorrect leading to a potential buffer over-run on 4K block size file systems (because the metadata block size is always 8K). Srclength is set to the maximum expected size of the decompressed block and it is block_size or 8K depending on whether a data or metadata block is being decompressed.
