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 of problem:
The following AVC denial appeared on a test machine; unfortunately we don't have a clear reproducer.

type=USER_AVC msg=audit(11/26/2014 07:17:20.862:839) : pid=1 uid=root auid=unset ses=unset subj=system_u:system_r:init_t:s0 msg='avc:  denied  { start } for auid=unset uid=unset gid=unset scontext=system_u:system_r:docker_t:s0 tcontext=system_u:system_r:init_t:s0 tclass=service  exe=/usr/lib/systemd/systemd sauid=root hostname=? addr=? terminal=?'

Version-Release number of selected component (if applicable):
systemd-208-18.el7.x86_64

Comment 1 Daniel Walsh 2014-12-02 15:41:00 UTC 
d021242a9461fda596cbb828979975faa2c95970 allows this in git.

It should be back ported to RHEL7/Fedor20/21.
Comment 2 Patrik Kis 2014-12-18 16:02:53 UTC 
Looks like fixed in selinux-policy-3.13.1-14.el7
