2021-07-27vcl: fix some risk after fork()liuyacan1-9/+17
1.Not only the session in state VCL_STATE_LISTEN_NO_MQ has no queue. Session in CLOSED also didn't. 2.Refresh vls->wrk_index in child process, or this value will become invalid if parent exit. 3.Set vlsh->vls_wrk_index once vls_worker_alloc() is called, then vls_get_worker_index() can be simplified.

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.
