qtdeclarative5-qtlocation-plugin does not use trust-store on session bus

[Jamie Strandboge]

Right now, qtdeclarative5-qtlocation-plugin connects to the system bus instead of the trust-store on the session bus. This is entirely understandable, since the trust store is not implemented yet. :) Indeed, the location service code has:

if (credentials.pid != pid || credentials.uid != uid)
        return Result::granted; // FIXME(tvoss): This should return rejected.

In order to provide contextual runtime prompting and per app access to the location service such that the user is aware that an app is using the location API, a trust-store will be implemented that the location service will integrate with and then the qtdeclarative5-qtlocation-plugin should connect on the session bus rather than the system bus.

Right now to bug #1223211, I am updating the location policy group to have (but this will need to be fixed):
# Description: Can access Location
# Usage: common
# session bus gives access to via the trust-store
dbus (receive, send)
     bus=session
     path="/com/ubuntu/location/Service"
     interface="com.ubuntu.location.Service"
     peer=(name="com.ubuntu.location.Service"),
dbus (receive, send)
     bus=session
     interface="com.ubuntu.location.Service.Session",

# FIXME: remove when trust-store is available since this would circumvent the
# trust-store
dbus (send)
     bus=system
     path=/org/freedesktop/DBus
     interface=org.freedesktop.DBus
     member=Hello
     peer=(name=org.freedesktop.DBus),
dbus (receive, send)
     bus=system
     path="/com/ubuntu/location/Service"
     interface="com.ubuntu.location.Service"
     peer=(name="com.ubuntu.location.Service"),
dbus (receive, send)
     bus=system
     interface="com.ubuntu.location.Service.Session",

Adding apparmor-easyprof-ubuntu task to update the policy group once qtdeclarative5-qtlocation-plugin starts using the session bus.

Adding location-service task for it to integrate with the trust-store.

For anyone implementing various parts of this, you can see a simple qml test program here: lp:~jdstrand/+junk/test-location/

I forgot about bug #1219164, so I marked it as a duplicate since this bug more fully captures everything that is needed.

Ok, after discussions with Thomas Voss I removed the duplicate bug status and marked this bug as Invalid. We want the location service to be one service on the system bus. It is the location service's job to call out to a service on the session bus to prompt the user (this is part of the trust-store design). As such, there is no need for qtdeclarative5-qtlocation-plugin or apparmor-easyprof-ubuntu to be updated.
