2017-07-30Make tcp active open data structures thread safeFlorin Coras1-3/+3
- 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>

2017-07-11Horizontal (nSessions) scaling draftDave Barach1-0/+6
- Data structure preallocation. - Input state machine fixes for mid-stream 3-way handshake retries. - Batch connections in the builtin_client - Multiple private fifo segment support - Fix elog simultaneous event type registration - Fix sacks when segment hole is added after highest sacked - Add "accepting" session state for sessions pending accept - Add ssvm non-recursive locking - Estimate RTT for syn-ack - Don't init fifo pointers. We're using relative offsets for ooo segments - CLI to dump individual session Change-Id: Ie0598563fd246537bafba4feed7985478ea1d415 Signed-off-by: Dave Barach <dbarach@cisco.com> Signed-off-by: Florin Coras <fcoras@cisco.com>
2017-06-22Improve svm fifo and tcp tx path performance (VPP-846)Florin Coras1-1/+6
- multiarch on svm fifo - avoid ip lookup on tx Change-Id: Iab0d85204a710979417bca1d692cc47877131203 Signed-off-by: Florin Coras <fcoras@cisco.com> Signed-off-by: Dave Barach <dbarach@cisco.com>
2017-06-19Overall tcp performance improvements (VPP-846)Florin Coras1-0/+2
- limit minimum rto per connection - cleanup sack scoreboard - switched svm fifo out-of-order data handling from absolute offsets to relative offsets. - improve cwnd handling when using sacks - add cc event debug stats - improved uri tcp test client/server: bugfixes and added half-duplex mode - expanded builtin client/server - updated uri socket client/server code to work in half-duplex - ensure session node unsets fifo event for empty fifo - fix session detach Change-Id: Ia446972340e32a65e0694ee2844355167d0c170d Signed-off-by: Florin Coras <fcoras@cisco.com>
2017-05-04Fixes and improvements in session hashtable keysClement Durand1-53/+35
Fix in v6 keys : * The copy of the keys was only partial A few suggestions are applied in this commit : * Since there are not so many unused fields, we avoid to memset 0 and prefer setting the unused fields to 0. * By using a cast, it seems painless to avoid allocating a structure for the keys creation.

2017-04-13Session layer refactoringFlorin Coras1-9/+14
Major refactoring of the session layer api - Add attatch api for application binding to the the session layer - Simplify listen/connect calls - Update application CLI - Add transport endpoint to accept callback - Associate segment manager to application and allow for multiple binds/connects per app Additional: - svm fifo cleanup - add fifo free, format fns - add fifo offset enqueue unit test Change-Id: Id93a65047de61afc2bf3d58c9b544339c02065af Signed-off-by: Florin Coras <fcoras@cisco.com> Signed-off-by: Dave Barach <dave@barachs.net>
2017-03-27TCP/session improvementsFlorin Coras1-1/+1
- Added svm fifo flag for tracking fifo dequeue events (replaces event length). Updated all code to switch to the new scheme. - More session debugging - Fix peek index wrap - Add a trivial socket test client - Fast retransmit/cc fixes - tx and rx SACK fixes and unit testing - SRTT computation fix - remove dupack/ack burst filters - improve ack rx - improved segment rx - builtin client test code Change-Id: Ic4eb2d5ca446eb2260ccd3ccbcdaa73c64e7f4e1 Signed-off-by: Florin Coras <fcoras@cisco.com> Signed-off-by: Dave Barach <dbarach@cisco.com>
