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
