* Squashfs: Valid filesystems are flagged as bad by the corrupted fs patchPhillip Lougher2009-03-121-17/+4
| | | | | | | | | | | | | | | | | | | | The corrupted filesystem patch added a check against zlib trying to output too much data in the presence of data corruption. This check triggered if zlib_inflate asked to be called again (Z_OK) with avail_out == 0 and no more output buffers available. This check proves to be rather dumb, as it incorrectly catches the case where zlib has generated all the output, but there are still input bytes to be processed. This patch does a number of things. It removes the original check and replaces it with code to not move to the next output buffer if there are no more output buffers available, relying on zlib to error if it wants an extra output buffer in the case of data corruption. It also replaces the Z_NO_FLUSH flag with the more correct Z_SYNC_FLUSH flag, and makes the error messages more understandable to non-technical users.

* Squashfs: Fix oops when reading fsfuzzer corrupted filesystemsPhillip Lougher2009-03-054-6/+15
| | | | | | | | | | 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.
