There are no new permissions or classes, IPv6 is managed along with IPv4 (e.g. a TCP socket refers to both protocols).

You can now provide IPv6 nodes with contexts, e.g.

nodecon ::1 ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff system_u:object_r:node_lo_t

In standard policy, the IPv4 loopback address has the same type, so they can be treated equivalently by security policy. You can, of course, specify different security contexts for IPv4 and IPv6 nodes if you want e.g. system_u:object_r:node_ipv6_lo_t

Logging has been extended to handle IPv6 addresses.

The checkpolicy tool now has generic policy version compatibility. It can read and write any version from 15 to 17, and the kernel will also be able to load any of these policy versions. The checkpoliy '-c' parameter takes a policy version argument to be used, and it recognises IPv6 addresses in debug mode.
