The bionic SRU test message occurred because I accidentally uploaded the
package with the entire old history. This bug has already been fixed
and the verification for bionic can be ignored.

Title:
thermald: change the default dbus policy, make it more restrictive
Status in thermald package in Ubuntu:
Fix Released
Status in thermald source package in Trusty:
Fix Released
Bug description:
org.freedesktop.thermald.conf default dbus policy should be more
restrictive
===
SRU Justification:
[Impact]
With the current dbus policy one can terminate thermald using:
dbus-send --system --dest=org.freedesktop.thermald /org/freedesktop/thermald
org.freedesktop.thermald.Terminate
thermald can be send dbus
..fortunately init respawns thermald, but the policy is not
restrictive enough, only root should be able to do this.
Justification:
This fix restricts the default policy so only root can send dbus
messages to thermald.
[Test Case]
How to reproduce:
dbus-send --system --dest=org.freedesktop.thermald /org/freedesktop/thermald
org.freedesktop.thermald.Terminate
thermald can be send dbus
then use: dmesg and see that init has respawned thermald (which means
it received the dbus message and handled it)
With the fix, the dbus-send message won't kill thermald and hence one
won't see the re-spawn message in dmesg.
[Regression Potential]
Cannot think of any, low to none. Thermald is not a default install,
it is a new packaging in Trusty and is currently op-in, so this change
has minimal impact. Regression potential is that users won't be able
to communicate to thermald via dbus-send, which is not the recommended
way to shut down thermald anyhow.
Tested today on an AMD64 trusty install.
