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
