2019-02-06transport: cleanupFlorin Coras1-3/+3
- move transport specific types to transport_types - add transport wrapper functions for interaction with transport protocol vfts Change-Id: I93f70d884585fc2f41c4a605e310c80e8a8972f2 Signed-off-by: Florin Coras <fcoras@cisco.com>
2019-02-04session: cleanup part 1Florin Coras2-38/+38
Rename core data structures. This will break compatibility for out of tree builtin apps. - stream_session_t to session_t - server_rx/tx_fifo to rx/tx_fifo - stream_session.h to session_types.h - update copyright Change-Id: I414097c6e28bcbea866fbf13b8773c7db3f49325 Signed-off-by: Florin Coras <fcoras@cisco.com>
2019-01-17tls: preallocate app sessions on connect/acceptFlorin Coras2-10/+22
Avoid allocating session and possibly reallocating thread session pool on builtin session rx. Change-Id: I70e7c604678b44ce8d22603489e247a2c5faa439 Signed-off-by: Florin Coras <fcoras@cisco.com>
2019-01-03Fix an issue in tls.cPing Yu1-1/+3
Curernt code will overwrite parent_app_api_context, and defer the setting after this value is used in callback. Change-Id: Ie16e432fd0f4214e6deff3aa3b58b3be824b0331 Signed-off-by: Ping Yu <ping.yu@intel.com>

2018-10-16tls: fix multi threaded medium scale test (VPP-1457)Florin Coras1-1/+4
- ensure session enqueue epoch does not wrap between two enqueues - use 3 states for echo clients app, to distinguish between starting and closing phases - force tcp fin retransmit if out of buffers while sending a fin Change-Id: I6f2cab46affd1148aba2a33fb6d58bcc54f32805 Signed-off-by: Florin Coras <fcoras@cisco.com>
2018-10-02tls: fix disconnects for sessions with pending dataFlorin Coras2-13/+59
TLS can enqueue events to itself when app session queue cannot be entirely drained. If a pending disconnect is handled before any such event, session layer may try to dequeue data on deallocated sessions.

2018-09-15tls: use application interface apisFlorin Coras1-15/+23
This also exposes app to tls sessions. As a result "sh session verbose" will show for each tls session both the application's session (app to tls) and the tls session (tls to tcp). Change-Id: I1e65c63362ce58f314e762d7db78b44479e1e3a5 Signed-off-by: Florin Coras <fcoras@cisco.com>

2018-08-16Fix a segment fault issue in TLSPing Yu1-2/+3
The root cause is it uses a dangling reference after memory move Need to call session_alloc first, then use index to get the app listener point Change-Id: If5b7e0d6ddc761e5327660c47ce620e375319b4d Signed-off-by: Ping Yu <ping.yu@intel.com>
