2018-01-25session: add support for memfd segmentsFlorin Coras1-10/+10
- update segment manager and session api to work with both flavors of ssvm segments - added generic ssvm slave/master init and del functions - cleanup/refactor tcp_echo - fixed uses of svm fifo pool as vector Change-Id: Ieee8b163faa407da6e77e657a2322de213a9d2a0 Signed-off-by: Florin Coras <fcoras@cisco.com>
2018-01-09api: refactor vlibmemoryFlorin Coras1-6/+4
- separate client/server code for both memory and socket apis - separate memory api code from generic vlib api code - move unix_shared_memory_fifo to svm and rename to svm_fifo_t - overall declutter Change-Id: I90cdd98ff74d0787d58825b914b0f1eafcfa4dc2 Signed-off-by: Florin Coras <fcoras@cisco.com>

2017-08-29session: segment manager improvementsFlorin Coras1-12/+17
- cleanup connects segment manager even if first - fix segment manager allocation for listen sessions - improve handling of process private segments (mheaps/main heap) - added segment manager cli Change-Id: Ic2ca97c3622ab2286d5fb5772aeb57680e64f769 Signed-off-by: Florin Coras <fcoras@cisco.com> Signed-off-by: Dave Wallace <dwallacelf@gmail.com>

- 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>

2017-06-01Improve fifo allocator performanceDave Barach1-0/+3
- add option to preallocate fifos in a segment - track active fifos with doubly linked list instead of vector - update udp redirect test code to read fifo pointers from API call instead of digging them up from fifo segment header - input-node based active-open session generator Change-Id: I804b81e99d95f8690d17e12660c6645995e28a9a Signed-off-by: Dave Barach <dave@barachs.net> Signed-off-by: Florin Coras <fcoras@cisco.com> Signed-off-by: Dave Barach <dbarach@cisco.com>
2017-04-24Session layer improvementsFlorin Coras1-0/+12
Among others: - Moved app event queue to shared memory segment - Use private memory segment for builtin apps - Remove pid from svm fifo - Protect session fifo (de)allocation - Use fifo event for session disconnects - Have session queue node poll in all wk threads Change-Id: I89dbf7fdfebef12f5ef2b34ba3ef3c2c07f49ff2 Signed-off-by: Florin Coras <fcoras@cisco.com>
2017-04-13Session layer refactoringFlorin Coras1-0/+106
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>
