2021-05-10session: use half-open sessions for vc establishmentFlorin Coras8-116/+111
Use half-open sessions to track virtual circuit connection establishment. These sesssions can only be allocated and freed by the thread that allocates half-open connections (main). Consequently, they can only be freed on half-open cleanup notifications from transports. Goal is to simplify state tracking within the session layer but it's also a first step towards allowing builtin apps to track and cleanup outstanding connects.

2021-05-07session: connects seg manager is always firstFlorin Coras3-77/+23
By convention, connects segment manager will be first. Therefore it will be the one with the first segment wherein lies the app's message queue. Saves us the trouble of allocating it on first connect, if app started by listening, and we no longer need to track if it's assignable to a listener or if it can be removed.

2021-05-03session: lookup listener with iface addressliuyacan1-0/+26
We add interface address to the global lookup table, so we should use it as the key when lookup listener. Otherwise, when multiple threads listen on 0.0.0.0 (local scope disable), duplicate listeners and sessions would be allocated but only one works.

2021-05-01vlib: refactor trajectory trace debug featureBenoît Ganne1-5/+0
trajectory trace has been broken for a while because we used to save the buffer trajectory in a vector pointed to in opaque2. This does not work well when opaque2 is copied (eg. because of a clone) as 2 buffers end up sharing the same vector. This dedicates a full cacheline in the buffer metadata instead when trajectory is compiled in. No dynamic allocation, no sharing, no tears.

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.
