Description Martin Kopun 2009-12-15 01:35:40 UTC

SELinux is preventing tuned "read" access on fifo_file.

Podrobný popis:

SELinux denied access requested by tuned. It is not expected that this access is
required by tuned and this access may signal an intrusion attempt. It is also
possible that the specific version or configuration of the application is
causing it to require additional access.

Povolení přístupu:

You can generate a local policy module to allow this access - see FAQ
(http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385) Please file a bug

You can add these rules for now using

# grep avc /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
