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.

Expected results:
No AVC denieds.
Comment 1 Robert Scheck 2013-03-22 15:53:04 UTC 
This is cross-referenced with Red Hat customer portal, case 00668208
Comment 2 Miroslav Grepl 2013-03-25 09:59:26 UTC 
Robert,
does it only want to search these dirs?
Comment 3 Robert Scheck 2013-03-27 17:24:17 UTC 
Miroslav, how do I figure out this best? This is the only AVC denieds as it
seems at least. Suggestions how to track down? Try dontaudits, enforce and
see and try if it is as expected? Unfortunately nearly all of the affected
systems are productive...
Comment 4 Miroslav Grepl 2013-04-03 08:30:31 UTC 
Probably the best is make a domain as permissive domains.

# semanage permissive -a DOMAIN

re-test

# ausearch -m avc -ts recent
# semanage permissive -d DOMAIN


But actually no need in this case. I am adding fixes to Fedora and will back port them.
Comment 5 Robert Scheck 2013-04-16 19:05:20 UTC 
I think it would be enough to make them dontaudit, because it seems to work
fine how it is (enforced).
