Summary: SELinux is preventing /usr/sbin/upsmon "getattr" access. Detailed Description: [upsmon has a permissive type (upsmon_t). This access was not denied.] SELinux denied access requested by upsmon. It is not expected that this access is required by upsmon 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://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385) Please file a bug report.

See also bug #537483 and bug #537632. All 3 alerts happen immediately after starting the ups service. I am using an APC BackUPS serial port UPS with a serial port to USB adapter to connect to my PC which does not have a serial port.
THey are basically the same bug. Reporting one would be sufficient. You can add these rules for now using # grep avc /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Fixed in selinux-policy-3.6.32-46.fc12.noarch

selinux-policy-3.6.32-46.fc12 has been submitted as an update for Fedora 12. http://admin.fedoraproject.org/updates/selinux-policy-3.6.32-46.fc12
Created attachment 369778 [details] SELinux is preventing /sbin/genericups "unlink" access on /var/run/nut/genericups-ups.
After updating selinux-policy and selinux-policy-targeted to the 3.6.32-46 test versions and stopping and starting the ups service, I only get one selinux message (attached above) instead of the previous three.
selinux-policy-3.6.32-46.fc12 has been pushed to the Fedora 12 testing repository. If problems still persist, please make note of it in this bug report. If you want to test the update, you can install it with su -c 'yum --enablerepo=updates-testing update selinux-policy'. You can provide feedback for this update here: http://admin.fedoraproject.org/updates/F12/FEDORA-2009-11672
selinux-policy-3.6.32-46.fc12 has been pushed to the Fedora 12 stable repository. If problems still persist, please make note of it in this bug report.
Immediately after updating to 3.6.32-46, stopping the ups service resulted in a single selinux message (same as the one in comment #6), which I reported as bug #540966. Restarting the service didn't generate any messages, nor do I see the three messages reported in this bug anymore.
