2024-01-09session: make app listener pool globalFlorin Coras1-4/+4
One less pointer chase when accepting sessions. Type: improvement Signed-off-by: Florin Coras <fcoras@cisco.com> Change-Id: I20dbb21d15d4a703f76e3b12f04a6f5b5d2a3cd8
2024-01-09session: support for cl port reuseFlorin Coras1-1/+12
Adds support for connectionless listener port reuse. Until now, cl listeners had fifos allocated to them and therefore only one app worker could ever listen, i.e., a session cannot have multiple fifos. To circumvent the limitation, this separates the fifos from the listener by allocating new cl sessions for each app worker that reuses the app listener. Flows are hashed to app worker cl sessions but, for now, this is not a consistent/fixed hash.

2023-09-04session: fix allocation of proxy fifosFlorin Coras1-0/+2
Fifos need to be synchronously allocated once a transport like tcp accepts a session. Since events are now delivered asynchronously, proxy apps must explicitly register a cb function that manages fifo allocation prior to being notified of connect event. Type: fix Fixes: 0242d30 Signed-off-by: Florin Coras <fcoras@cisco.com> Change-Id: I7df973b7014e53e0766ea2bdc61e9871160bc18b
2023-08-09session: async rx event notificationsFlorin Coras1-274/+243
Move from synchronous flushing of io and ctrl events from transports to applications to an async model via a new session_input input node that runs in interrupt mode. Events are coalesced per application worker. On the one hand, this helps by minimizing message queue locking churn. And on the other, it opens the possibility for further optimizations of event message generation, obviates need for rx rescheduling rpcs and is a first step towards a fully async data/io rx path.

2023-03-14session vcl: refactor builtin tx event for main txFlorin Coras1-1/+1
Rename unused SESSION_IO_EVT_BUILTIN_TX to SESSION_IO_EVT_TX_MAIN and leverage it for non-connected udp tx. Non-connected udp sessions are listeners and are therefore allocated on main thread. Consequently, whenever session queue node is not polling main, tx events generated by external applications might be missed or processed with some delay. To solve this, request that apps use SESSION_IO_EVT_TX_MAIN tx events as opposed to SESSION_IO_EVT_TX and send that to first worker as opposed to main.

2023-03-08session: Use session->thread_index to correctly retrieve the sessionSteven Luong1-1/+3
For non-connected udp, when retrieving the subscriber session to send the notification, it uses the current worker thread index whereas the subscriber session is actually on the main thread. Using the worker thread may cause a crash since the corresponding session may not be valid in the worker thread context and even if it is valid, it is the wrong session. This scenario is seen when the application forks and adds subscribers to the worker thread session.

2022-03-18session: add infra for safe pool reallocsFlorin Coras1-0/+1
This is not to be used lightly. The idea is to forces pool reallocs to be done only on main thread with a barrier to make sure pools are always reallocated without peekers/readers. If rpcs are delayed and the pool runs out of elements, workers will block waiting for barrier and force the realloc. Consumers of this api should be session layer and transports.
