Description John Poelstra 2008-05-28 23:48:43 UTC
Description of problem:
as root: 'service network restart'


Version-Release number of selected component (if applicable):
selinux-policy-targeted-3.3.1-51.fc9.noarch

How reproducible:
100%


Summary:

SELinux is preventing ps (dhcpc_t) "sys_nice" to <Unknown> (dhcpc_t).

Detailed Description:

[SELinux is in permissive mode, the operation would have been denied but was
permitted due to permissive mode.]

SELinux denied access requested by ps. It is not expected that this access is
required by ps 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) Or you can disable
SELinux protection altogether. Disabling SELinux protection is not recommended.
Please file a bug report (http://bugzilla.redhat.com/bugzilla/enter_bug.cgi)
against this package.

You can allow this for now.

# audit2allow -M mypol -l -i /var/log/audit/audit.log
