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.

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.

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.

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.

  To: selinux-refpolicy; +Cc: Lukas Vrabec

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.

 ## Allow unconfined executables to make their heap memory executable.  Doing this is a really bad idea. Probably indicates a badly coded executable, but could indicate an attack. This executable should be reported in bugzilla
