AVC for df from logwatch

[Steven Stern]

This has appeared the past two mornings.  The initial triggering event
was probably the last kernel update:

Dec 16 08:59:09 Installed: kernel-3.6.10-2.fc17.x86_64

**********************************

SELinux is preventing /usr/bin/df from getattr access on the directory
/sys/kernel/config.

*****  Plugin restorecon (99.5 confidence) suggests
*************************

If you want to fix the label.
/sys/kernel/config default label should be sysfs_t.
Then you can run restorecon.
Do
# /sbin/restorecon -v /sys/kernel/config

*****  Plugin catchall (1.49 confidence) suggests
***************************

If you believe that df should be allowed getattr access on the config
directory by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep df /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
