2017-04-06Use thread local storage for thread indexDamjan Marion1-1/+1
This patch deprecates stack-based thread identification, Also removes requirement that thread stacks are adjacent. Finally, possibly annoying for some folks, it renames all occurences of cpu_index and cpu_number with thread index. Using word "cpu" is misleading here as thread can be migrated ti different CPU, and also it is not related to linux cpu index.

2017-03-27TCP/session improvementsFlorin Coras2-32/+44
- 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>

2017-03-13VPP-659 Improve tcp/session debugging and testingFlorin Coras1-4/+6
- event-logging support for tcp and session layer - improvements to uri test code - builtin_server on port 1234 - use the CLOSEWAIT timer when we rx FIN in FIN_WAIT_2 state Change-Id: Ibc445f164b2086b20323bf89c77cffd3059f570f Signed-off-by: Florin Coras <fcoras@cisco.com> Signed-off-by: Dave Barach <dbarach@cisco.com> Signed-off-by: Dave Barach <dave@barachs.net>
2017-03-10VPP-659 TCP improvementsFlorin Coras2-8/+8
- builtin test echo server - fix SYN-ACK retransmit canceling - avoid sending spurious ACK if in LAST_ACK - improved client dummy test app - renamed tx fifo dequeuing and sending functions to avoid confusion - improved RST handling Change-Id: Ia14aad3df319540dcf6e6a4e18a9f8d423a4b83b Signed-off-by: Florin Coras <fcoras@cisco.com> Signed-off-by: Dave Barach <dave@barachs.net>
