Summary: SELinux is preventing /sbin/iptables-multi access to a leaked /proc/mtrr file descriptor. Detailed Description: [iptables has a permissive type (iptables_t). This access was not denied.] SELinux denied access requested by the iptables command. It looks like this is either a leaked descriptor or iptables output was redirected to a file it is not allowed to access. Leaks usually can be ignored since SELinux is just closing the leak and reporting the error. The application does not use the descriptor, so it will run properly. If this is a redirection, you will not get output in the /proc/mtrr. You should generate a bugzilla on selinux-policy, and it will get routed to the appropriate package. You can safely ignore this avc. Allowing Access: You can generate a local policy module to allow this access - see FAQ (http://docs.fedoraproject.org/selinux-faq-fc5/#id2961385) Additional Information: Source Context

Miroslav could you add dontaudit $1 mtrr_device_t:file write; to dev_dontaudit_write_mtrr for F12. ajayr, How did you get this to happen? Fixed in selinux-policy-3.7.14-4.fc13.noarch
selinux-policy-3.7.15-1.fc13 has been submitted as an update for Fedora 13. http://admin.fedoraproject.org/updates/selinux-policy-3.7.15-1.fc13
seems like I just hit this as well. I was running fully up2date F13 and I installed the Virtualization group. After the virt packages finished installing I ran: service libvirtd start and out these popped.....
Mind you it doesn't reproduce now by simply restarting libvirtd....
