Description Andre Naehring 2013-03-25 19:34:19 UTC
Description of problem:
- first install system-config-kdump:
$ sudo yum install -y system-config-kdump

run the program:
$ sudo system-config-kdump

enable kdump

configure kdump, set  filtering settings with following activated:

- zero pages
- free pages

the level should be 17.

Now try to apply the ruleset for kdump.
SELinux is preventing /usr/bin/systemctl from 'search' accesses on the directory log.

*****  Plugin catchall (100. confidence) suggests  ***************************

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