[SELinux]: Add support for DCCP
This patch implements SELinux kernel support for DCCP
(http://linux-net.osdl.org/index.php/DCCP), which is similar in
operation to TCP in terms of connected state between peers.
The SELinux support for DCCP is thus modeled on existing handling of
TCP.
A new DCCP socket class is introduced, to allow protocol
differentation. The permissions for this class inherit all of the
socket permissions, as well as the current TCP permissions (node_bind,
name_bind etc). IPv4 and IPv6 are supported, although labeled
networking is not, at this stage.
Patches for SELinux userspace are at:
http://people.redhat.com/jmorris/selinux/dccp/user/
I've performed some basic testing, and it seems to be working as
expected. Adding policy support is similar to TCP, the only real
difference being that it's a different protocol.
