2021-06-05vcl: epoll error handling fixes and improvementsFlorin Coras2-6/+22
- return VPPCOM_EEXIST if attempting to re-add a session - return VPPCOM_ENOENT if the session to be removed is not epolled - generate EPOLLIN if adding it through a mod operation on a session that has data and did not have the event previously set.

2021-03-29svm session vcl: per app rx message queuesFlorin Coras2-2/+21
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.

2021-03-22vcl: fix libc epoll pwait starvedwanghanlin2-1/+5
We call vls_epoll_wait with 0 timeout to process unhandled_evts_vector in ldp_epoll_pwait_eventfd. But vls_epoll_wait will then call vppcom_epoll_wait_eventfd to process events in event queue. If there are continuous events to be handled, then libc_epoll_pwait have no chance to be called.
