2018-05-03tcp: fix echo server rx retries counter vec allocFlorin Coras1-0/+2
If sessions are not preallocated, the rx retries counters are not correctly validated/initialized Change-Id: Iaf7456f3a0e2181fcea0c370613d694f8e98276d Signed-off-by: Florin Coras <fcoras@cisco.com>

2018-04-18udp/session: refactor to support dgram modeFlorin Coras1-42/+62
- 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 Coras1-4/+18
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.

2018-02-14session: support local sessions and deprecate redirectsFlorin Coras1-2/+19
Memfd backed shared memory segments can only be negotiated over sockets. For such scenarios, the existing redirect mechanism that establishes cut-through sessions does not work anymore as the two peer application do not share such a socket. This patch adds support for local sessions, as opposed to sessions backed by a transport connection, in a way that is almost transparent to the two applications by reusing the existing binary api messages. Moreover, all segment allocations are now entirely done through the segment manager valloc, so segment overlaps due to independent allocations previously required for redirects are completely avoided. The one notable characteristic of local sessions (cut-through from app perspective) notification messages is that they carry pointers to two event queues, one for each app peer, instead of one. For transport-backed sessions one of the queues can be inferred but for local session they cannot. Change-Id: Ia443fb63e2d9d8e43490275062a708f039038175 Signed-off-by: Florin Coras <fcoras@cisco.com>
2018-02-05session: segment manager refactorFlorin Coras1-2/+3
- use valloc as a 'central' segment baseva manager - use per segment manager segment pools and use rwlocks to guard them - add session test that exercises segment creation - embed segment manager properties into application since they're shared - fix rw locks Change-Id: I761164c147275d9e8a926f1eda395e090d231f9a Signed-off-by: Florin Coras <fcoras@cisco.com>
2018-01-26session: move builtin apps to their own folderFlorin Coras1-0/+485
This consolidates builtin apps under session-apps folder. It also removes duplicate builtin echo server/client implementations. Change-Id: I75ed879399c5aa9b75b1eb38b33aedf69dd8df3f Signed-off-by: Florin Coras <fcoras@cisco.com>
