IPv6 support available

IPv6 support available

[James Morris]

A set of preliminary patches providing IPv6 support may be found at:
http://people.redhat.com/jmorris/selinux/ipv6/

The kernel patch requires recent -mm kernels, and ipv6-exthdrs-core.patch 
needs to be applied if IPv6 is compiled as a module.

The kernel patches are expected to be submitted to mainline after 2.6.5 is 
released.

Any review or testing of the IPv6 code will be appreciated.

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.
