Default nspluginwrapper policy issue

Hi,


Summary:

SELinux is preventing npviewer.bin (nsplugin_t) "getattr" to /dev/dri/card0
(dri_device_t).

Detailed Description:

SELinux denied access requested by npviewer.bin. It is not expected that
this

access is required by npviewer.bin 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 /dev/dri/card0,

restorecon -v '/dev/dri/card0'

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.

Do you think it will need to read/write this device?
