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-2011:0526 0 normal SHIPPED_LIVE selinux-policy bug fix and enhancement update 2011-05-19 09:37:41 UTC

Description Eduard Benes 2010-09-15 07:58:10 UTC 
Description of problem:
Configuring cmirrord to start on boot time produces AVC denial. Currently cmirrord_t is in permissive domain and thus the action is allowed (success=yes).
Starting the cmirrord service after boot works and does not produce any AVC denials. It should be noted, the service is uncofigured and using defaults.

# semanage permissive -l | grep cmirrord_t
cmirrord_t

Version-Release number of selected component (if applicable):
cmirror-2.02.72-8.el6.x86_64
selinux-policy-3.7.19-54.el6.noarch

How reproducible:
always

Steps to Reproduce:
1. # chkconfig cmirrord on
2. reboot
3. # ausearch -m avc

Comment 1 Daniel Walsh 2010-09-15 12:20:22 UTC 
Miroslav, I believe this should be dontaudited and permissive should be removed from this domain.

I agree it should be dontaudited and also the cmirrord domain is ready to go without permissive.
