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:

A customer was upgrading from RHEV-H '20130501.0.el6_4' to '20130709.0.el6_4' from CD/DVD. The upgrade process completed, but during the subsequent reboot the system panic'ed in sidtab_context_to_sid(), which is an selinux routine.

It appears that the customer had tried to disable selinux some time previously by modifying '/etc/selinux/config' with "SELINUX=disabled" and then persisting this file and rebooting. After the reboot I believe that they probably then set selinux into permissive mode.


Version-Release number of selected component (if applicable):

RHEV-H '20130709.0.el6_4'

Additional info:

I've never seen anything like it...

Without a reproducer or even maybe a crash drump, I'm going to have to go with solar flares.  We haven't touched that code in many many years and I've never seen a similar panic...

Closing as worksforme since we cannot reproduce the issue and based on responses from selinux team.
