Merge branch 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6
Pull crypto fixes from Herbert Xu:
"This push fixes the following issues:
- buffer overread in RSA
- potential use after free in algif_aead.
- error path null pointer dereference in af_alg
- forbid combinations such as hmac(hmac(sha3)) which may crash
- crash in salsa20 due to incorrect API usage"
* 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6:
crypto: salsa20 - fix blkcipher_walk API usage
crypto: hmac - require that the underlying hash algorithm is unkeyed
crypto: af_alg - fix NULL pointer dereference in
crypto: algif_aead - fix reference counting of null skcipher
crypto: rsa - fix buffer overread when stripping leading zeroes
