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 Cong Wang 2012-08-03 03:07:14 UTC 
Description of problem:

Openvswitch service starts the following daemons:

    * ovs-vswitchd, a daemon that implements the switch, along with 
      a companion Linux kernel module for flow-based switching.

    * ovsdb-server, a lightweight database server that ovs-vswitchd
      queries to obtain its configuration.

    * ovs-brcompatd, a daemon that allows ovs-vswitchd to act as a
      drop-in replacement for the Linux bridge in many environments, 
      along with a companion Linux kernel module to intercept bridge 
      ioctls.

All of them need policy.

Comment 2 Milos Malik 2012-08-03 08:16:11 UTC 
Are the daemons you talk about related to quantum-openswitch-agent service ?

We have this policy in RHEL7/Fedora.

quantum.fc:/usr/bin/quantum-openvswitch-agent	--	gen_context(system_u:object_r:quantum_exec_t,s0)
Comment 4 Cong Wang 2012-08-03 08:39:16 UTC 
It looks like quantum-openvswitch-agent is a quantum plugin for openvswitch? I am not a virt people, so know very little about openstack.
Comment 5 Michal Trunecka 2012-09-21 08:00:14 UTC 
Cong, is there any openvswitch RPM available to install on RHEL6 or is it recommended to be installed from tar.gz?
Comment 6 Cong Wang 2012-09-21 08:25:23 UTC 
RPM package is not available yet, you need to build it from spec file. You can find it here:

http://git.engineering.redhat.com/?p=users/tgraf/openvswitch-rhel6.git
Comment 8 Miroslav Grepl 2012-10-15 18:26:55 UTC 
Is already the package available from brew?
Comment 9 Cong Wang 2012-10-16 02:19:07 UTC 
Try the RPM from Thomas:
http://file.bos.redhat.com/tgraf/openvswitch/
Comment 10 Miroslav Grepl 2012-10-23 11:07:55 UTC 
I added an intial openvswitch policy to selinux-policy-3.7.19-175.el6

How to test.

1. install these builds
2. semodule -d unconfined
3. setenforce 0
4. re-test it
5. ausearch -m avc > /tmp/openvswitch.log

and attach this log. Thank you.

6. semodule -e unconfined
7. setenforce 1
