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

 

Playing with it, I came up with the attached minimal set of rules to get
the test case working. There's a whole majority of Network Manager dbus
calls still being denied, and three allowed. Despite that I assume this
minimal set reveals the discussed "too much", but it might be useful
reference.

Using the patch as is results in log noise due to default being
apparently "audit deny", and I didn't know how to "deny everything
without audit like before, but allow these three exceptions to pass".

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.
