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().

2022-09-20vcl: align the RST behaviour with kernelYacan Liu1-1/+13
When ESTABLISHED TCP connection is terminated by an RST packet, EPOLLHUP + EPOLLRDHUP would be updeliever by VCL. If not using VPP, app would receive EPOLLHUP + EPOLLERR + EPOLLIN(if requested) + EPOLLRDHUP(if requested). libevent will interpret the two cases as different EV combinations. Below is the code snippet for libevent v2.12: if (what & EPOLLERR) { ev = EV_READ | EV_WRITE; } else if ((what & EPOLLHUP) && !(what & EPOLLRDHUP)) { ev = EV_READ | EV_WRITE; } else { if (what & EPOLLIN) ev |= EV_READ; if (what & EPOLLOUT) ev |= EV_WRITE; if (what & EPOLLRDHUP) ev |= EV_CLOSED; } Type: fix Signed-off-by: Yacan Liu <liuyacan@corp.netease.com> Change-Id: Ice3d2861183b6ea499f66b727bbe175eeae5cb05

Sometimes VPP rejects application connection requests due to various reasons. Some errors application can retry to get a successful connection. In a non-blocking session, VCL sends EPOLLHUP. An application can call a new API vppcom_session_get_error to find the details and retry depending on the error.

2022-06-10vcl: fix iperf3 server crash issue when it runs over vpp host stack.Liangxing Wang1-1/+8
Issue: Let iperf3 server run via ldp and vcl on top of vpp's host stack. If iperf3 client connects this iperf3 server with tcp MSS setting option, iperf3 server will always crash. Root cause: When MSS option is specified by iperf3 client, iperf3 server will recreate the listening socket firstly, then call setsockopt() to set MSS immediately. Iperf3 code can be referred here: https://github.com/esnet/iperf/blob/58332f8154e2140e40a6e0ea060a418138291718/src/iperf_tcp.c#L186. However, in vcl layer vpp_evt_q of this recreated session is not allocated yet. So iperf3 server crashes with vpp_evt_q null pointer access. Fix: Add session vpp_evt_q null pointer check in vcl_session_transport_attr(). Add a vcl test case for this MSS option scenario.
