2021-03-22vcl: fix libc epoll pwait starvedwanghanlin1-1/+2
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.

2020-08-12vcl: support multi-threads with session migrationhanlin1-3/+8
Currently, mutlti-threads only support one dispatch thread and multiple worker threads, eventually only dispatch thread is a vcl worker and can interact with epoll. This patch will register all threads as vcl worker, and then each thread can interact with epoll now. Moreover, session migration also supported, such as socket created in thread A and used (bind, connect and etc.) in thread B.

2020-05-20vcl: nest vcl_mq_epfd to support epoll_wait without high CPU usagehanlin1-2/+118
Now, libc epfd and vls epfd are independent and can only epoll_wait independently without timeout, then app calling epoll_wait will occupy high CPU. So we nest vcl_mq_epfd into libc epfd when using eventfd with VPP, and then we can only epoll_wait libc epfd with specified timeout.

2019-12-30vcl: hold errno when calling LDBGhanlin1-1/+5
Type: fix Call trace of LDBG: LDBG->clib_warning->_clib_error->dispatch_message->os_puts->writev However, writev will hijacked by LDP, and then execute following code: if ((errno = -ldp_init ())) return -1; Now, errno will be set. Because we always call LDBG just before return from ldp_accept4, listen, and etc. So errno will be overwritted after LDBG called.
