Description ritz 2009-12-01 19:39:18 UTC
Summary:

SELinux is preventing /usr/bin/python "sys_rawio" access.

Detailed Description:

[getSystemId has a permissive type (abrt_t). This access was not denied.]

SELinux denied access requested by getSystemId. It is not expected that this
access is required by getSystemId 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 2009-12-01 20:02:09 UTC
You can add these rules for now using

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