Description Allen Kistler 2009-03-05 07:11:33 UTC 
Description of problem:
SELinux is keeping kerneloops from reporting a kernel oops that occurs during boot.

Version-Release number of selected component (if applicable):
selinux-policy-3.6.7-1.fc11
(also dbus-1.2.4-4permissive-4.fc11 and kerneloops-0.12-3.fc11)

How reproducible:
Always

Steps to Reproduce:
1. boot
2. read the setroubleshoot browser pop-up (or the audit log directly)
  
Actual results:
AVC denial (see below)

Expected results:
No AVC denial

Additional info:
The audit log entry follows.  Note that "dbus-deamon-lau" is probably
dbus-daemon-launch-helper.

node=vtest type=AVC msg=audit(1236230578.12:13): avc: denied { execute } for pid=2519 comm="dbus-daemon-lau" name="kerneloops" dev=dm-0 ino=85586 scontext=system_u:system_r:system_dbusd_t:s0-s0:c0.c1023 tcontext=system_u:object_r:kerneloops_exec_t:s0 tclass=file
Comment 1 Allen Kistler 2009-03-05 07:37:30 UTC 
I set enforcement to permissive, and I get a few more logs (but different) along the same lines (i.e., a kerneloops theme).
