Subject[patch 19/58] unreached code in selinux_ip_postroute_iptables_compat() (CVE-2009-1184)
2.6.29-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Eugene Teo <eteo@redhat.com>

Not upstream in 2.6.30, as the function was removed there, making this a
non-issue.

Node and port send checks can skip in the compat_net=1 case. This bug
was introduced in commit effad8d.
