2017-08-02Fix tcp tx buffer allocationFlorin Coras1-1/+1
- Make tcp output buffer allocation macro an inline function - Use per ip version per thread tx frames for retransmits and timer events - Fix / parameterize tcp data structure preallocation - Add a couple of gdb-callable show commands - Fix local endpoint cleanup Change-Id: I67b47b7570aa14cb4634b6fd93c57cd2eacbfa29 Signed-off-by: Florin Coras <fcoras@cisco.com> Signed-off-by: Dave Barach <dave@barachs.net>
2017-07-30Make tcp active open data structures thread safeFlorin Coras1-1/+1
- 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>
2017-07-21Improvements to tcp rx path and debuggingFlorin Coras1-3/+19
- Increment rcv_nxt for fin packets - Call tcp_segment_rcv only if buffer has data - Parse rcv opts before deleting half-open connection - Fix initial rcv_wnd - Improved event logging Change-Id: I9b83c04f432c4cec832c480b03e534deff02c3b1 Signed-off-by: Florin Coras <fcoras@cisco.com>
2017-07-15Fixes and improved tcp/session debuggingFlorin Coras1-34/+232
- Fix rx sack option parsing - Add session sack scoreboard tracing and replaying - Add svm fifo tracing and replaying - Scoreboard/svm fifo ooo segment reception fixes - Improved overall debugging Change-Id: Ieae07eba355e66f5935253232bb00f2dfb7ece00 Signed-off-by: Florin Coras <fcoras@cisco.com>
2017-07-11Horizontal (nSessions) scaling draftDave Barach1-21/+78
- 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>
2017-06-09Implement sack based tcp loss recovery (RFC 6675)Florin Coras1-9/+17
- refactor existing congestion control code (RFC 6582/5681). Handling of ack feedback now consists of: ack parsing, cc event detection, event handling, congestion control update - extend sack scoreboard to support sack based retransmissions - basic implementation of Eifel detection algorithm (RFC 3522) for detecting spurious retransmissions - actually initialize the per-thread frame freelist hash tables - increase worker stack size to 2mb - fix session queue node out-of-buffer handling - ensure that the local buffer cache vec_len matches reality - avoid 2x spurious event requeues when short of buffers - count out-of-buffer events - make the builtin server thread-safe - fix bihash template threading issue: need to paint -1 across uninitialized working_copy_length vector elements (via rebase from master) Change-Id: I646cb9f1add9a67d08f4a87badbcb117980ebfc4 Signed-off-by: Florin Coras <fcoras@cisco.com> Signed-off-by: Dave Barach <dbarach@cisco.com>
