In a previous post I used the secilc binary to load an additional test policy. Little did I know (and that's actually embarrassing because it was one of the things I complained about) that you can just use the CIL policy as modules directly.

With this I mean that a CIL policy as mentioned in the previous post can be loaded like a prebuilt .pp module:

~# semodule -i test.cil
~# semodule -l | grep test
test

That's all that is to it. Loading the module resulted in the test port to be immediately declared and available:

~# semanage port -l | grep test
test_port_t                    tcp      1440

In hindsight, it makes sense that it is this easy. After all, support for the old-style policy language is done by converting it into CIL when calling semodule so it makes sense to immediately put the module (in CIL code) ready to be taken up.
