Basically, yes. We could add a new variable/function that gates the access control checks in selinux_ib_pkey_access() and selinux_ib_endport_manage_subnet(); the checks would be enabled when there was Infiniband configuration loaded with the policy. Without the IB config loaded, all the checks would end up being just a domain check against unlabeled_t, which isn't very interesting, so we would just drop the checks. -- paul moore www.paul-moore.com
