AVC log

Description of problem:
Our test  /CoreOS/sudo/Regression/bz866637-sudo-l-does-not-parse-information-after-the fails with AVC in Fedora Rawhide.

There are different labels between F20 and Fedora Rawhide:
On my F20 machine:
-rw-r--r--. root root system_u:object_r:sysctl_kernel_t:s0 /proc/sys/kernel/core_pattern
On Rawhide:
-rw-r--r--. root root system_u:object_r:usermodehelper_t:s0 /proc/sys/kernel/core_pattern

In attached file there is also the same error for nmbd.

Comment 2 Daniel Walsh 2014-07-15 22:47:21 UTC 
Any idea why these apps are reading these files.  Can we turn on full auditing on the test machines, so that we get all AVC messages.
Comment 3 Jaroslav Reznik 2015-03-03 16:07:48 UTC

Fedora 22 changed to end-of-life (EOL) status on 2016-07-19. Fedora 22 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
