could be red herring, but guess that error could really make nm not do proper default route replace...
in nm-system.c:1043 you see the code that will give up trying to replace the gateway in case the add_ip4_route_to_gateway call fails... /* Try adding a direct route to the gateway first */ gw_route = add_ip4_route_to_gateway (parent_ifindex, ext_gw, parent_mss); if (!gw_route) goto out; /* Try adding the original route again */ err = replace_default_ip4_route (ifindex, int_gw, mss); if (err != 0) { nm_netlink_route_delete (gw_route); nm_log_err (LOGD_DEVICE | LOGD_VPN | LOGD_IP4, "(%s): failed to set IPv4 default route (pass #2): %d", iface, err); } else success = TRUE; out: if (gw_route) rtnl_route_put (gw_route); g_free (iface); -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1307981 Title: [touch] randomly messed up routing with recent trusty images To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1307981/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
