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.

2021-05-10session: use half-open sessions for vc establishmentFlorin Coras1-48/+48
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.

2021-04-06session: basic support for interrupt modeFlorin Coras1-4/+26
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 Coras1-0/+6
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.
