* Squashfs: extend decompressor framework to handle compression optionsPhillip Lougher2011-02-281-0/+1
| | | | | | | | | | | | | | | | 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.

* Squashfs: simplify CONFIG_SQUASHFS_LZO handlingPhillip Lougher2011-01-131-3/+0
| | | | | | | Get rid of messy repeated #if(n)def CONFIG_SQUASHFS_LZO code in decompressor.c Signed-off-by: Phillip Lougher <phillip@lougher.demon.co.uk>
* Squashfs: move squashfs_i() definition from squashfs.hPhillip Lougher2011-01-131-5/+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>

* squashfs: add new extended inode typesPhillip Lougher2010-05-171-1/+11
| | | | | | | Add new extended inode types that store the xattr_id field. Also add the necessary code changes to make xattrs visibile. Signed-off-by: Phillip Lougher <phillip@lougher.demon.co.uk>
* squashfs: add xattr id supportPhillip Lougher2010-05-171-0/+6
| | | | | | | This patch adds support for mapping xattr ids (stored in inodes) into the on-disk location of the xattrs themselves. Signed-off-by: Phillip Lougher <phillip@lougher.demon.co.uk>
* Squashfs: add a decompressor frameworkPhillip Lougher2010-01-201-7/+7
| | | | | | | | | This adds a decompressor framework which allows multiple compression algorithms to be cleanly supported. Also update zlib wrapper and other code to use the new framework. Signed-off-by: Phillip Lougher <phillip@lougher.demon.co.uk>
* Squashfs: factor out remaining zlib dependencies into separate wrapper filePhillip Lougher2010-01-201-0/+2
| | | | | | | | 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>

* Squashfs: Fix oops when reading fsfuzzer corrupted filesystemsPhillip Lougher2009-03-051-1/+1
| | | | | | | | | | 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.
