Because of new bluetooth_socket which is part of extended_socket_class
policy capability, it's possible to control which SELinux domains can
use bluetooth wireless technology. Default value of the boolean is
turned off.

Missed a deny_bluetooth.
I'm also a little uneasy with adding this access here, as this would
seem to be a side effect to a simple stream socket connection. Perhaps
there should be a new interface like bluetooth_client(). It might also
make sense in bluetooth_role(), as there is a generic socket class rule
in there too.

Hi Chris,
I'll update deny_bluetooth() to allow_bluetooth().
So, you're suggesting create new interface bluetooth_client() but all
bluetooth related stuff there, and use this interface in tunable_policy
block instead of just allowing using bluetooth socket?
bluetooth_role() should be fixed to use only bluetooth_socket, not the
general one. I'll create PR also for it.
Thanks,
Lukas.

bluetooth_client() would have the rules of bluetooth_stream_connect()
and then the allow_bluetooth conditional rule. The stream socket
connection can remain unconditional, if the bluetooth_socket access is
sufficient to block bluetooth use.

* [PATCH] Introduce allow_bluetooth boolean

Because of new bluetooth_socket which is part of extended_socket_class
policy capability, it's possible to control which SELinux domains can
use bluetooth wireless technology. Default value of the boolean is
turned off.

Two observations:
1. are you using 4 spaces ident instead of 8 space tab indentation?
2. this rule is questionable:
allow init_t self:bluetooth_socket { create_socket_perms listen };

I looked into this and tracked the above down to this:
https://bugzilla.redhat.com/show_bug.cgi?id=1592223
In that report the bluetoothd executable file was mislabeled and that is why it ended up in init_t.
Please address the indents and remove the above rule.
