And in the linux/net/ipv6/udp.c file I don't see where the msg->msg_flags is checked for that, or passed to a function that would check it. And from the IPv4 land I think it just means don't use a gateway, not ignore the routes. I tried the setsocketopt SO_DONTROUTE too and no luck. Then I tried the IPV6_NEXTHOP cmsg header, and it doesn't seem to be supported yet. - To unsubscribe from this list: send the line "unsubscribe linux-net" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
