Summary: SELinux is preventing audispd "read" access on fifo_file. Detailed Description: [SELinux is in permissive mode. This access was not denied.] SELinux denied access requested by audispd. It is not expected that this access is required by audispd 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.

Looks like init is leaking access to its fifo file.
If I could get an lsof result while this is running it'd be helpful. I'll try to reproduce when I get home.

Repro with selinux-policy-3.7.9-1.fc13
Repro with selinux-policy-3.7.9-4.fc13
Casey and Daniel: Would my lsof output be of any help? This issue seems to occur during the boot cycle. Is there a method to run lsof at boot?
Ray seems to be fixes on my machine. # audit2allow -i /tmp/out #============= audisp_t ============== #!!!! This avc is allowed in the current policy allow audisp_t init_t:fifo_file read; -bash-4.1# rpm -q selinux-policy selinux-policy-3.7.9-3.fc13.noarch
Might have been a fluke, on my end. I had to reformat my F13 test bed due to some RAWHIDE(F14)/F13 crossover updates that compromised the validity of testing I performed on 2010-02-19. I will retest this evening, time permitting.
I have recreated my test bed and updated accordingly. So far so good. No recurrence of this issue. I did install the selinux-policy-3.7.9-4.fc13.noarch from the F13 Testing repo.
Spoke too soon. On reboot I was able to reproduce the error.
