As I understand it, they only shipped a minimal policy and a cupsd policy module as a starting point, to match the original configuration of AppArmor. I'm not sure what progress has been made since then. You can of course try building and using the upstream refpolicy with a more complete configuration. > And the access vector really confuses me.

I'd guess that insmod_t is an unconfined domain in that policy (typical for a targeted-style policy), and thus is unrestricted. -- Stephen Smalley National Security Agency -- This message was distributed to subscribers of the selinux mailing list.
