Public bug reported:
Cannot send MMS messages with combined contexts in case the WiFi is
enabled, for some operators. Combined contexts are able to handle
internet data and MMS data. For the operator for which I've seen the
bug, the data is:
$ /usr/share/ofono/scripts/list-contexts
[ /ril_0 ]
[ /ril_0/context1 ]
Password =
MessageCenter = http://www.pepephone.com
Name = MMS Pepephone
Username =
Protocol = ip
Preferred = 0
IPv6.Settings = { }
Settings = { }
MessageProxy = 10.138.255.43:8080
Type = internet
AccessPointName = gprs.pepephone.com
Active = 0
Sending an MMS with cellular data and WiFi enabled fails for this
operator when using a combined context. Disabling WiFi I was able to
send the MMS.
The error I see in ~/.cache/upstart/dbus.log is:
E0513 09:55:03.254148 4565 file_upload.cpp:345] Upload ID{

See attached the tcpdump of the packets sent when this happened. Some
quick analysis shows that the uploader is sending through the WiFi
(192.168.1.40) instead of using 10.60.155.62, so it is clearly a routing
problem. The MMS proxy has private address 10.138.255.43 so it is not
reachable from WiFi.
Found in mako vivid-proposed image #195.
