Description Gregory Trivett 2010-10-02 00:52:40 UTC
Summary:

SELinux is preventing /usr/lib64/nspluginwrapper/plugin-config access to a
leaked /dev/dri/card0 file descriptor.

Detailed Description:

[plugin-config has a permissive type (nsplugin_config_t). This access was not
denied.]

SELinux denied access requested by the plugin-config command. It looks like this
is either a leaked descriptor or plugin-config output was redirected to a file
it is not allowed to access. Leaks usually can be ignored since SELinux is just
closing the leak and reporting the error. The application does not use the
descriptor, so it will run properly. If this is a redirection, you will not get
output in the /dev/dri/card0. You should generate a bugzilla on selinux-policy,
and it will get routed to the appropriate package. You can safely ignore this
avc.

Allowing Access:

You can generate a local policy module to allow this access - see FAQ
(http://docs.fedoraproject.org/selinux-faq-fc5/#id2961385)
