Why would getnameinfo(NI_NUMERICHOST) fail here? The code in
ikev2_msg.c is:
--8<--
log_info("%s: %s %s from %s to %s msgid %u, %ld bytes%s", __func__,
print_map(exchange, ikev2_exchange_map),
(flags & IKEV2_FLAG_RESPONSE) ? "response" : "request",
print_host((struct sockaddr *)&msg->msg_local, NULL, 0),
print_host((struct sockaddr *)&msg->msg_peer, NULL, 0),
betoh32(hdr->ike_msgid),
ibuf_length(buf), isnatt ? ", NAT-T" : "");
-->8--
Maybe msg->msg_local is corrupt?
