Description Pavel Šimerda (pavlix) 2015-06-05 09:49:11 UTC
Description of problem:
systemctl start/restart radvd
SELinux is preventing radvd from using the 'dac_override' capabilities.

*****  Plugin dac_override (91.4 confidence) suggests   **********************

If you want to help identify if domain needs this access or you have a file with the wrong permissions on your system
Then turn on full auditing to get path information about the offending file and generate the error again.

Turn on full auditing
# auditctl -w /etc/shadow -p w
Try to recreate AVC. Then execute
# ausearch -m avc -ts recent
If you see PATH record check ownership/permissions on file, and fix it, 
otherwise report as a bugzilla.

*****  Plugin catchall (9.59 confidence) suggests   **************************

If you believe that radvd should have the dac_override capability 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 radvd /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
