While fuzzing our 3.10 based kernel we observed some crashes, e.g:
http://lkml.kernel.org/r/<cact4y+ae-pnunclbdqkfq9y7qivn_g6heus7t1rpknphfmh...@mail.gmail.com>
It appears that 3.10-stable lacks some crypto related fixes. Here is my attempt
to backport them.
Many patches didn't apply cleanly, so to make sure that my conflict resolution
is correct I compared it with other stable trees.
