Add Transport Layer Security (TLS) and Datagram Transport Layer Security (DTLS). The protocols provide communications privacy for L4 protocols such as TCP & UDP.
TLS (and DTLS) protocol is composed of two layers, 1. TLS Record Protocol 2. TLS Handshake Protocol While TLS Handshake Protocol helps in establishing security parameters by which client and server can communicate, TLS Record Protocol provides the connection security. TLS Record Protocol leverages symmetric cryptographic operations such as data encryption and authentication for providing security to the communications. Cryptodevs that are capable of offloading TLS Record Protocol may perform other operations like IV generation, header insertion, atomic sequence number updates and anti-replay window check in addition to cryptographic transformations. In record write operations, message content type is a per packet field which is used in constructing the TLS header. One session is expected to handle all types of content types and so, 'rte_crypto_op.aux_flags' is used for passing the same. The support is added for TLS 1.2, TLS 1.3 and DTLS 1.2.
