Subject: Crypto Fixes for 4.15

Hi Linus: 

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.

Eric Biggers (5):
      crypto: rsa - fix buffer overread when stripping leading zeroes
      crypto: algif_aead - fix reference counting of null skcipher
      crypto: af_alg - fix NULL pointer dereference in
      crypto: hmac - require that the underlying hash algorithm is unkeyed
      crypto: salsa20 - fix blkcipher_walk API usage
