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 Brian J. Murrell 2016-11-08 17:15:40 UTC 
SELinux is preventing /usr/bin/cdcc from read access on the file unix.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that cdcc should be allowed read access on the unix file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep cdcc /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Hi Brian, bugs 1393013, 1393015, 1393020, 1393030 have most likely the same cause. Unfortunately, I don't know it. I would appreciate if you could help me find it. Thanks for the report.
Comment 7 Lukas Vrabec 2017-10-12 12:17:30 UTC 
We're going to close this bug as WONTFIX because

 * of limited capacity of selinux-policy developers
 * the bug is related to EPEL component or 3rd party SW only
 * the bug appears in unsupported configuration 

We believe this bug can be fixed via a local policy module.
For more information please see:

If you disagree, please re-open the bug.
