Sigh. I used the old tag by accident. Attached is a pull request for one
that got pulled Herbert. The only difference was that I rebased it on the
cryptodev tree - no other changes were made.
Apologies for that.

Hi, Could you pull this into the net-next tree please (it has been pulled into the crypto tree[1])? This provides the Kerberos-5 crypto parts needed by the AF_RXRPC RxGK (GSSAPI) security class. In the future, it could also be used by NFS and SunRPC as much of the code is abstracted from there. This is a prerequisite for the rxrpc patches[2]. It does a couple of things: (1) Provide an AEAD crypto driver, krb5enc, that mirrors the authenc driver, but that hashes the plaintext, not the ciphertext. This was made a separate module rather than just being a part of the authenc driver because it has to do all of the constituent operations in the opposite order - which impacts the async op handling. Testmgr data is provided for AES+SHA2 and Camellia combinations of authenc and krb5enc used by the krb5 library. AES+SHA1 is not provided as the RFCs don't contain usable test vectors. (2) Provide a Kerberos 5 crypto library. This is an extract from the sunrpc driver as that code can be shared between sunrpc/nfs and rxrpc/afs. This provides encryption, decryption, get MIC and verify MIC routines that use and wrap the crypto functions, along with some functions to provide layout management. This supports AES+SHA1, AES+SHA2 and Camellia encryption types. Self-testing is provided that goes further than is possible with testmgr, doing subkey derivation as well.
