Description Wolfgang Rupprecht 2009-11-26 16:26:05 UTC
Summary:

SELinux is preventing /usr/sbin/asterisk "setcap" access.

Detailed Description:

[asterisk has a permissive type (asterisk_t). This access was not denied.]

SELinux denied access requested by asterisk. It is not expected that this access
is required by asterisk 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://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385) Please file a bug
report.

Comment 1 Wolfgang Rupprecht 2009-11-26 16:27:45 UTC
this is the companion to bug 541657

It occurred after a reboot at asterisk startup time.

Comment 3 Daniel Walsh 2009-11-30 19:07:44 UTC

You can add these rules for now using

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