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 2 RHEL Program Management 2011-07-06 00:08:06 UTC 
This request was evaluated by Red Hat Product Management for
inclusion in the current release of Red Hat Enterprise Linux.
Because the affected component is not scheduled to be updated
in the current release, Red Hat is unfortunately unable to
address this request at this time. Red Hat invites you to
ask your support representative to propose this request, if
appropriate and relevant, in the next release of Red Hat
Enterprise Linux. If you would like it considered as an
exception in the current release, please ask your support
representative.
Comment 3 David Zeuthen 2011-07-06 18:52:09 UTC 
Looks like a SELinux policy problem to me. Reassigning for further investigation.
Comment 4 Daniel Walsh 2011-07-06 19:40:05 UTC 
I have no idea what it is complaining about.  I take it you do not see any AVC messages in /var/log/audit/audit.log?  I think dbus is trying to listen for messages from the kernel telling it that SELinux policy has been reloaded, could this me what is going on?
Comment 5 John Reiser 2011-07-06 22:17:53 UTC

Comment 6 Daniel Walsh 2011-07-07 12:54:04 UTC 
Steve any ideas?
Comment 7 Eric Paris 2011-07-07 13:11:06 UTC 
Is the 4 the errno?  EINTR?  No idea who is printing that message or what it means off the top of my head...
Comment 9 Steve Grubb 2011-08-29 14:06:57 UTC 
This looks very much like Bug #700507, just a different component.
Comment 11 Stephen Smalley 2012-02-03 14:18:36 UTC 
libselinux/src/avc_internal.c:avc_netlink_receive().
Should probably be retrying rather than returning error on EINTR there.
