2023-08-08vcl: Fix the ldp init checkGao Feng1-1/+5
Maybe some function calls the wrapper funtion like read which invokes the ldp_init_check in the other libs as a constructor before ldp_constructor. Then the ldp has been initialized already when ldp_constructor is invoked. And it's normal case, we shouldn't treat it as an error. So ldp_init should return success if ldp is initialized already instead of an assert. Type: fix Change-Id: Ifa2a7b1d5471981a3f840b14a4fa5d48fb1f1374 Signed-off-by: Gao Feng <gfree.wind@outlook.com>

2023-07-19vcl: zero out cmsg for recvmsg APISteven Luong1-0/+1
When msg->msg_controllen is set in recvmsg, the caller wants to receive additional information about the messages. However, they might not always be available. In that case, we should clear cmsg since the caller uses CMSG_NXTHDR which might access uninitialized fields in cmsg.

2023-02-16vcl: fix incorrect ldp worker in ldp_epoll_pwait()Liangxing Wang1-1/+5
For some apps(e.g. wrk2) upon vpp hoststack, ldp_epoll_pwait() is called. In this function, epoll fd was created on one thread, but it is now used on another thread. The vcl worker index is still invalid, so the fetched ldp worker is also invalid and can corrupt some already allocated memory. Just as the ldp_epoll_pwait_eventfd(), make sure the vcl worker is valid before getting the ldp worker in ldp_epoll_pwait().

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.

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.
