Yes, but why is this bug assigned to selinux-policy, it is a kernel bug. This request was evaluated by Red Hat Product Management for inclusion in a Red Hat Enterprise Linux maintenance release. Product Management has requested further review of this request by Red Hat Engineering, for potential inclusion in a Red Hat Enterprise Linux Update release for currently deployed products. This request is not yet committed for inclusion in an Update release. Yes, there is a bug for kernel. I just wanted to test it also by Milos and Karel because of policy changes. Everything what you need to know is stated in the original kernel bug together with tests.
The policy changes just added interfaces to support secmark.
Basically you will make sure secmark.te policy can be compiled/loaded which means no interfaces miss.
So this is a test scenario for you:
---
cat > secmark.te << EOF
policy_module(secmark, 1.0)
# Type Definitions
require {
type xguest_t;
type avahi_t;
attribute domain;
}
attribute external_packet;
type internal_packet_t;
corenet_packet(internal_packet_t)
type dns_external_packet_t, external_packet;
corenet_packet(dns_external_packet_t)
type http_external_packet_t, external_packet;
corenet_packet(http_external_packet_t)
type external_packet_t, external_packet;
corenet_packet(external_packet_t)
EOF
# make -f /usr/share/selinux/devel/Makefile secmark.pp
# semodule -i secmark.pp
# semodule -d unlabelednet
