Summary:

SELinux is preventing pppd "create" access on <Unknown>.

Detailed Description:

SELinux denied access requested by pppd. It is not expected that this access is
required by pppd 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 (http://bugzilla.redhat.com/bugzilla/enter_bug.cgi) against this package.

Comment 1 Daniel Walsh 2009-09-04 13:48:32 UTC
This is an upgrade problem in rawhide.  Please stop and restart pppd and you should not see this AVC any longer.

We have taken away the transition for pppd from unconfined_t,  So if you updated when pppd was connected you would see this error.  

Sorry about that.  Please test the new policy and make sure everything works correctly (No AVC's)  Also make sure that /etc/resolv.conf gets the right label.
# ls -lZ /etc/resolv.conf
-rw-r--r--. root root system_u:object_r:net_conf_t:s0  /etc/resolv.conf
