2021-04-26session: fix race condition in fifo allocationliuyacan3-43/+39
Under some timing conditions,VCL may receive CONNECTED/ACCEPTED event before ADD_SEGMENT event. Timing example: 2 threads call segment_manager_alloc_session_fifos() parallelly Thread 1 Thread 2 sm read lock | | | try to alloc fifo =>failed | | | sm read unlock | | | sm write lock | | | add segment | | | sm write unlock | | sm read lock | | | try to alloc fifo=>successful sm read lock | | sm read unlock | | | emit CONNECTED/ACCEPTED emit ADD_SEGMENT event | sm read unlock This commit move ADD_SEGMENT notification under the protection of the write lock in some scenarios.

2021-04-23session: set fifo's session index before vcl attachliuyacan1-0/+2
Current implementation may have timing issue: 1. The TCP 3-way-handshake is completed but the app is busy and does not process the CONNECTED event. 2. VPP receive some data from peer and try to send a RX event to VCL, but the fifo's client session index is not initialized yet. So this event will be sent to incorrect session 0.

2021-04-06session: basic support for interrupt modeFlorin Coras4-4/+176
Experimental support for session layer interrupt mode. When enabled (use-private-rx-mqs must be set) session queue node switches to interrupt state when lightly loaded, i.e., no events and less than 1 vector/dispatch. Because transport protocols require a periodic time update, when in interrupt state the session queue node workers register a timerfd with the unix-epoll-input node that when triggered signals, i.e., wakes up, the queue node. Under light load, the timer is set to trigger every 1ms whereas if no session is allocated, the worker moves to idle state and the timeout is set to 100ms.

2021-03-29svm session vcl: per app rx message queuesFlorin Coras8-101/+496
Add option to use per app private segments for app to vpp message queues, as opposed to exposing internal message queues segment. When so configured, internal message queues are still polled by the session queue node but external app message queues are handled by a new input node (appsl-rx-mqs-input) that runs in interrupt state. Signaling of the node, when mqs receive new messages, is done through eventfds epolled by worker epoll input nodes.
