* stop passing nameidata to ->lookup()Al Viro2012-07-14
| | | | | | | | | Just the flags; only NFS cares even about that, but there are legitimate uses for such argument. And getting rid of that completely would require splitting ->lookup() into a couple of methods (at least), so let's leave that alone for now... Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

* make d_splice_alias(ERR_PTR(err), dentry) = ERR_PTR(err)Al Viro2011-07-20
| | | | | | ... and simplify the living hell out of callers Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
* deuglify squashfs_lookup()Al Viro2011-07-20
| | | | | | | | d_splice_alias(NULL, dentry) is equivalent to d_add(dentry, NULL), NULL so no need for that if (inode) ... in there (or ERR_PTR(0), for that matter) Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

* Squashfs: handle corruption of directory structurePhillip Lougher2011-03-15
| | | | | | | | | | | | | | | | | | Handle the rare case where a directory metadata block is uncompressed and corrupted, leading to a kernel oops in directory scanning (memcpy). Normally corruption is detected at the decompression stage and dealt with then, however, this will not happen if: - metadata isn't compressed (users can optionally request no metadata compression), or - the compressed metadata block was larger than the original, in which case the uncompressed version was used, or - the data was corrupt after decompression This patch fixes this by adding some sanity checks against known maximum values.

* Squashfs: factor out remaining zlib dependencies into separate wrapper filePhillip Lougher2010-01-20
| | | | | | | | 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>
