vcl: align the RST behaviour with kernel
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
