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.

Comment 4 Milos Malik 2016-02-08 09:54:05 UTC 
Is it possible that AVCs appeared before the selinux-policy = 3.13.1-60.el7_2.3 was installed?

# rpm -qa selinux\*

Found 2 semantic av rules:
   allow systemd_logind_t user_tmp_t : dir { getattr mounton search open } ; 
   allow systemd_logind_t user_tmp_type : dir { ioctl read write create getattr setattr lock relabelfrom relabelto unlink link rename mounton add_name remove_name reparent search rmdir open } ;

Comment 6 Milos Malik 2016-02-08 15:04:28 UTC 
Let's wait for an explanation from the developers. Either the AVC has something to do with mount points or I don't know why it appeared.
Comment 7 Miroslav Grepl 2016-04-29 07:46:41 UTC 
We need to back port fixes from Fedora.
