Description Laurent Rineau 2010-08-16 09:43:07 EDT
Summary:

SELinux is preventing /bin/bash "search" access on /home.

Detailed Description:

SELinux denied access requested by sh. It is not expected that this access is
required by sh and this access may signal an intrusion attempt. It is also
possible that the specific version or configuration of the application is
causing it to require additional access.

Allowing Access:

You can generate a local policy module to allow this access - see FAQ
(http://docs.fedoraproject.org/selinux-faq-fc5/#id2961385) Please file a bug
report.

Comment 1 Laurent Rineau 2010-08-16 09:44:39 EDT
Related to bug #624440: same reporter, same conf (actually same machine), but a different AVC.
Comment 2 Laurent Rineau 2010-08-16 12:13:00 EDT
Sorry. I probable launched some parts of ups by hand, during the installation of mgeopt-psp. That would explain the AVCs.

I have rebooted, and upsd started without any AVCs in ausearch -m acs -ts recent.
