SELinux is preventing /usr/sbin/NetworkManager "unlink" access on

Detailed Description:

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

audit2allow suggests:

#============= NetworkManager_t ==============
allow NetworkManager_t etc_t:file unlink;

Comment 1 Daniel Walsh 2009-09-25 16:28:52 UTC
Does networkmanager really need to unlink this file?  Does it write it also?

Comment 2 Gene Czarcinski 2009-09-25 16:37:58 UTC
I don't know .. ask Dan Williams
