Silo 032 has long pending networking fixes that now have seen more
recent work and the silo might be in shape for landing.

As an interested party in this networking related bug (among many),
could you please give 032 a whirl on vivid-overlay (xenial also
available) and test your networking in general in addition to this
particular bug? If we see no regressions - and we do see fixes - we
could try landing the silo.

Upgrade with 'citrain device-upgrade 32 0000'.

Title:
  QNetworkAccessManager hangs when in flight mode

Status in qtbase-opensource-src package in Ubuntu:
  Fix Released
Status in thumbnailer package in Ubuntu:
  Triaged
Status in qtbase-opensource-src package in Ubuntu RTM:
  New

Bug description:
  Testing the fix:

  - Update rc-proposed (vivid) to citrain device-upgrade 32 0000
  - Optional: If you want to test using the 'generic' bearer plugin instead of the Network Manager bearer, either do not upgrade ubuntu-touch-session or move away the file /etc/profile.d/qt_networkmanager_bearer.sh
  - Reboot

  When my phone is in flight mode, HTTP requests made using
  QNetworkAccessManager seem to hang rather than erroring out
  immediately.

  From my tests, it looks like the HTTP request is blocked until the
  flight mode is disabled and a network connection is reestablished.
  This is contrary to the documentation, which states:

  """If the network is not accessible the network access manager will
  not process any new network requests, all such requests will fail with
  an error. Requests with URLs with the file:// scheme will still be
  processed."""

  http://doc.qt.io/qt-5/qnetworkaccessmanager.html#networkAccessible-
  prop

  By running strace on my test program, it doesn't even look like it
  attempts to open a TCP connection when blocked in flight mode.
