nspluginwrapper policy issue

[Rahul Sundaram]

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?

Sorry. I have no idea why it would and if that is a valid thing to do or 
not.
