commit dcbff39da3d815f08750552fdd04f96b51751129 upstream.
match_token() expects a NULL terminator at the end of the token list so
that it would know where to stop. Not having one causes it to overrun
to invalid memory.
In practice, passing a mount option that omfs didn't recognize would
sometimes panic the system.

omfs: sanity check cluster size2010-07-10T18:38:11ZBob Copeland2010-07-06T15:16:46Zurn:sha1:8800a044c71a128633cf3febaf4780531a991334
A corrupt filesystem could have a bad cluster size; this could result in
the filesystem allocating too much space for files if too large, or
getting stuck in omfs_allocate_block if too small. The proper range is
1-8 blocks.

If the free space bitmap pointer is corrupted such that it lies outside
of the number of blocks in the filesystem, print a message and fail the
mount so the user can fix it offline.

omfs: check bounds on block numbers before passing to sb_bread2010-07-10T18:37:06ZBob Copeland2008-09-06T21:51:53Zurn:sha1:f068272cb2f134a194b93e94a8e0672bfce48cd8
In case of filesystem corruption, passing unchecked block numbers into
sb_bread can result in an infinite loop in __getblk(). Introduce a wrapper
function omfs_sbread() to check the block numbers and to also perform the
clus_to_blk() scaling.

In the error path of omfs_fill_super(), the FS super block info
(sbi) is not being freed. Correct this.
