[Bug 1404188] Re: QNetworkSession::isOpen() always returns false

 

I tried a working connectivity-api bearer plugin (verified with
unconfined test app) with the attached example app, and I still got app
armor errors:

Syslog> Jan 21 06:55:34 ubuntu-phablet dbus[1809]: apparmor="DENIED"
operation="dbus_method_call"  bus="session"
path="/com/ubuntu/connectivity1/NetworkingStatus"
interface="org.freedesktop.DBus.Properties" member="GetAll" mask="send"
name="com.ubuntu.connectivity1" pid=11241
label="com.ubuntu.developer.mzanetti.nmsessiontest_myapp_0.1"
peer_pid=2631 peer_label="unconfined"

Even if we wanted to move to connectivity-api, we would need to fix
those.

After looking further atks the connectivity-api, it is quite limited and
cannot even detect when network is using mobile data or wifi.

We could:
* Use connectivity-api knowing that bearer functionality will be mostly broken, but should allow basic bearer use, and allow QNAM & friends to function unhindered.

* add some functionality to connectivity-api

Bug description:
  Using QNetworkSession::isOpen() in confined apps on a phone running
  vivid always returns false. This might be an apparmor thing, however,
  I couldn't find any REJECTED entries in log files.

  The test app in lp:~mzanetti/+junk/nmsessiontest can reproduce the
  issue. Open this project in ubuntu-sdk's qtcreator and run it on a
  vivid device. Press the button and watch the debug prints.

  On a vivid-desktop or a RTM based phone it will print "all is well".
  On a vivid phone however, it'll print "network session not open..."

  This used to work fine at least back in utopic images.
