Description Jay Turner 2008-09-23 13:09:46 EDT
Description of problem:
Getting the following with selinux-policy-2.4.6-159.el5, NetworkManager-0.7.0-0.11.svn4082.el5 and dbus-1.1.2-9.el5.  Even relabeled the filesystem after installation of the new selinux-policy.

SELinux is preventing dbus-daemon (system_dbusd_t) "execute_no_trans" to
/lib/dbus-1/dbus-daemon-launch-helper (system_dbusd_exec_t).

Detailed Description:

SELinux denied access requested by dbus-daemon. It is not expected that this
access is required by dbus-daemon 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:

Sometimes labeling problems can cause SELinux denials. You could try to restore
the default system file context for /lib/dbus-1/dbus-daemon-launch-helper,

restorecon -v '/lib/dbus-1/dbus-daemon-launch-helper'

If this does not work, there is currently no automatic way to allow this access.
Instead, 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.

Looks like Dan squashed these with 2.4.6-160.el5.  Will close out once it appears in a tree.
