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);

Title:
[touch] randomly messed up routing with recent trusty images
Status in “network-manager” package in Ubuntu:
Confirmed
Bug description:
I have no clue when exactly it started (probably before image 290),
but since a while i experience random issues where the browser
suddenly doesnt find websites anymore ... digging deeper i can see
that the routing table is completely messed up having two default
routes:
root@ubuntu-phablet:~# route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
0.0.0.0 37.85.159.174 0.0.0.0 UG 0 0 0
rmnet_usb1
0.0.0.0 192.168.2.1 0.0.0.0 UG 0 0 0 wlan0
37.85.159.172 0.0.0.0 255.255.255.252 U 0 0 0
rmnet_usb1
192.168.2.0 0.0.0.0 255.255.255.0 U 9 0 0 wlan0
i did not roam or switch networks, this phone was constantly on wlan in the
same room.
afer a reboot the routing is normal:
root@ubuntu-phablet:~# route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
0.0.0.0 192.168.2.1 0.0.0.0 UG 0 0 0 wlan0
37.84.75.140 0.0.0.0 255.255.255.252 U 13 0 0
rmnet_usb0
192.168.2.0 0.0.0.0 255.255.255.0 U 9 0 0 wlan0
