All of the netlink classes currently tested by the selinux-testsuite + classes
tested by the attached patch are supported (at the same time by the kernel
and by the policy) on RHEL-7.3.
Unfortunately, selinux-policy for RHEL-6.9 and RHEL-7.2 does not recognize
following classes:
netlink_connector_socket, netlink_crypto_socket, netlink_fib_lookup_socket,
netlink_generic_socket, netlink_iscsi_socket, netlink_netfilter_socket,
netlink_rdma_socket, netlink_scsitransport_socket.
Based on my RHEL-7.3 and RHEL-7.4 test results, the netlink tests can
be safely executed on RHEL-7.3 and higher.
You're right about splitting the netlink tests into at least 2 subsets:
RHEL<7.3 (which also covers RHEL-6) and RHEL>=7.3. I will take a look
at the commits you provided and let you know.
