handle ofono MMS host routes that are hostnames and not IP addresses

[Mathieu Trudel-Lapierre]

NM should be able to handle (read: resolve) MMS proxy settings as strings for hostnames: if the value is a hostname rather than an IP address, we should try to resolve it to generate a proper host route to the MMS proxy.

Not a bug in ofono; marking as Invalid for ofono.

In progress for NM; we'll fix this via a dispatcher script.

[Mathieu Trudel-Lapierre (cyphermox)]

This was fixed in lxc-android-config (0.172), via a dispatcher script as mentioned above. Closing as Fix Released.

[Tony Espy (awe)]

For added detail, the dispatcher script mentioned above is 03mmsproxy and is installed to /etc/NetworkManager/dispatcher.d.

The script is written in Python does the following:

1) it does some minor error checking on modem_path ( 'DEVICE_IPATH' ) and connection ( 'CONNECTION_ID' )

2) it makes a synchronous dbus call to get the properties of the specified ofono context

3) is use socket.gethostbyname to resolve the MMS proxy

4) if uses subprocess.call to invoke the "ip route" command to configure the proxy
