Make sure that GNOME 3.14's captive portal handling is disabled on Tails/Jessie
This ticket is about ensuring this functionality is disabled in Tails 2.0. For research about potentially using such functionality, see #7950, its parent ticket and blueprint.
See https://help.gnome.org/misc/release-notes/3.14/. It might be good for us, but it might as well be dangerous and in need to be disabled.
This is implemented via the “connectivity” feature, see e.g.
contrib/fedora/rpm/20-connectivity-fedora.conf in NM’s Git
tree
to see what kind of parameters it can take: basically, it just calls
home via a HTTP request, and checks if it gets the expected response —
see NetworkManager.conf(5) for details.
It also seems that another component of this feature (the “login agent”)
was implemented in GNOME Shell (see
https://bugzilla.gnome.org/show_bug.cgi?id=609870, that gives a little
bit more details); see e.g. grep -iE (connectivity|portal) in Jessie’s
GNOME Shell source => we should have a close look there too. Frederic
Peters wrote that “Up in the stack GNOME Shell will automatically popup
a window embedding a webkit widget set on the given URI (and thus,
displaying the captive portal)”.
