Subject: [PATCH net-next v2 0/5] net: tls: TLS 1.3 support

This patchset adds 256bit keys and TLS1.3 support to the kernel TLS
socket.  

TLS 1.3 is requested by passing TLS_1_3_VERSION in the setsockopt
call, which changes the framing as required for TLS1.3.  

256bit keys are requested by passing TLS_CIPHER_AES_GCM_256 in the
sockopt.  This is a fairly straightforward passthrough to the crypto
framework.  

256bit keys work with both TLS 1.2 and TLS 1.3

TLS 1.3 requires a different AAD layout, necessitating some minor
refactoring.  It also moves the message type byte to the encrypted
portion of the message, instead of the cleartext header as it was in
TLS1.2.  This requires moving the control message handling to after
decryption, but is otherwise similar.

V1 -> V2

The first two patches were dropped, and sent separately, one as a
bugfix to the net tree.

Dave Watson (5):
  net: tls: Support 256 bit keys
  net: tls: Refactor tls aad space size calculation
  net: tls: Refactor control message handling on recv
  net: tls: Add tls 1.3 support
  net: tls: Add tests for TLS 1.3
