Description dtdraganov 2010-07-10 04:06:36 UTC 
Summary:

SELinux is preventing /sbin/dhclient "search" access on /var/lib/wicd.

Detailed Description:

SELinux denied access requested by dhclient. It is not expected that this access
is required by dhclient 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.

Comment 1 Miroslav Grepl 2010-07-12 16:34:24 UTC 
Dan,
dhcpc needs to read /var/lib/wicd/dhclient.conf

Can we get an update for F12 too? (Should I file a separate bug?) I have selinux-policy-3.6.32-118.fc12.noarch:
