RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Red Hat Product Errata RHBA-2011:1511 0 normal SHIPPED_LIVE selinux-policy bug fix and enhancement update 2011-12-06 00:39:17 UTC

Comment 1 Miroslav Grepl 2011-10-04 10:57:10 UTC 
Dan,
I see I should also backport unlabelenet stuff.
Comment 2 Daniel Walsh 2011-10-04 18:44:16 UTC 
Yes, but why is this bug assigned to selinux-policy, it is a kernel bug.
Comment 3 RHEL Program Management 2011-10-04 18:51:13 UTC 
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.
Comment 4 Miroslav Grepl 2011-10-05 05:03:16 UTC 
Yes, there is a bug for kernel. 

I just wanted to test it also by Milos and Karel because of policy changes.
Comment 6 Miroslav Grepl 2011-10-06 09:15:11 UTC 
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
