2018-04-18udp/session: refactor to support dgram modeFlorin Coras1-3/+53
- adds session layer support for datagram based protocols - updates udp to work in pure connectionless and datagram mode. The existing connected mode is now 'accessible' for apps as a dummy UDPC, as in, connected udp, protocol. - updates udp_echo, echo client, echo server code to work in datagram mode.

2018-03-02session: first approximation implementation of tlsFlorin Coras1-1/+3
It consists of two main parts. First, add an application transport type whereby applications can offer transport to other applications. For instance, a tls app can offer transport services to other applications. And second, a tls transport app that leverages the mbedtls library for tls protocol implementation.

2017-12-11session: generalize handling of network transportsFlorin Coras1-3/+4
- compute session type out of transport and network protos - make session, session lookup and session queue code network protocol agnostic This does not update the session layer to support non-ip network layer protocols Change-Id: Ifc2f92845e158b649d59462eb7d51c12af536691 Signed-off-by: Florin Coras <fcoras@cisco.com>

- Cleanup half-open connections and timers on the right thread - Ensure half-open connection and transport endpoint pools are thread safe - Enqueue TX events to the correct vpp thread in the builtin client - Use transport proto in transport connections instead of session type Change-Id: Id13239a206afbff6f34a38afa510fe014e4b2049 Signed-off-by: Florin Coras <fcoras@cisco.com> Signed-off-by: Dave Barach <dave@barachs.net>
