Panic in selinux routine sidtab_context_to_sid() during RHEV-H upgrade.
Last modified: 2013-08-30 09:25:45 EDT
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):
I tried to reproduce it here, but to no avail.
Steps to Reproduce:
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.
