Description Eduard Benes 2010-06-09 09:52:01 UTC

I found following AVC denial in logs while testing audisp-remote plugin with "network_failure_action = stop".

Summary:

SELinux is preventing /sbin/audisp-remote "getcap" and "setcap" access .

Detailed Description:

SELinux denied access requested by audisp-remote. It is not expected that this
access is required by audisp-remote 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.

Allowing Access:

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