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.

Description Terry Wilson 2013-06-10 22:19:17 UTC 
Description of problem:

When using Quantum 2013.1.2 with netns support, several SELinux denials are produced.

Version-Release number of selected component (if applicable):

selinux-policy-3.7.19-195.el6_4.10.noarch

How reproducible:

Always

Steps to Reproduce:
1. Install openstack via packstack on a RHEL 6.4 VM with the 2013-06-10.1 puddle
2. Log into the installed target VM and:
   quantum net-create net1
   quantum subnet-create net1 10.0.0.0/24 --name subnet1
   Log into horizon and create a keypair and image (I used https://launchpad.net/cirros/trunk/0.3.0/+download/cirros-0.3.0-x86_64-disk.img)
   Launch an instance using the cirros image
3. Witness the avc denials

Actual results:

AVC denials:

Expected results:

No AVC denials

Additional info:

I haven't noticed anything not working because of the denials.
