Multicast packets did not appear to be getting > delivered to the network namespaces of the guest hosts, and further > inspection showed that the incoming route was pointing to the loopback > device of the host, not the guest. This lead to the wrong network namespace > being picked up by sockets (like ICMP). Fix this by using the correct > network namespace when creating the inbound route entry. > > Signed-off-by: Benjamin LaHaise <bcrl@...ck.org> Applied. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
