Squashfs: fix corruption checks in squashfs_lookup()

2013-09-06T03:57:53+00:00

The dir_count and size fields when read from disk are sanity
checked for correctness.  However, the sanity checks only check the
values are not greater than expected.  As dir_count and size were
incorrectly defined as signed ints, this can lead to corrupted values
appearing as negative which are not trapped.

Squashfs: fix corruption check in get_dir_index_using_name()

2013-09-06T03:57:52+00:00

Patch "Squashfs: sanity check information from disk" from
Dan Carpenter adds a missing check for corruption in the
"size" field while reading the directory index from disk.

It, however, sets err to -EINVAL, this value is not used later, and
so setting it is completely redundant.  So remove it.

Errors in reading the index are deliberately non-fatal.  If we
get an error in reading the index we just return the part of the
index we have managed to read - the index isn't essential,
just quicker.

Squashfs: sanity check information from disk

2013-08-29T00:23:29+00:00

We read the size of the name from the disk, but a larger name than
expected would cause memory corruption.

stop passing nameidata to ->lookup()

2012-07-14T12:34:32+00:00

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...

deuglify squashfs_lookup()

2011-07-20T05:44:24+00:00

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)
