A common source of mistakes when authoring sepolicy is properly setting up property sets. This is a 3 part step of: 1. Allowing the unix domain connection to the init/property service 2. Allowing write on the property_socket file 3. Allowing the set on class property_service The macro unix_socket_connect() handled 1 and 2, but could be confusing for first time policy authors. 3 had to be explicitly added. To correct this, we introduce a new macros: set_prop(sourcedomain, targetprop) This macro handles steps 1, 2 and 3. No difference in sediff is expected.
