Description Kevin Gagnon 2009-12-06 16:03:31 UTC
Summary:

SELinux is preventing /usr/sbin/asterisk "execute_no_trans" access on
/usr/sbin/asterisk.

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 Daniel Walsh 2009-12-06 16:11:10 UTC
You can add these rules for now using

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