Summary:

SELinux is preventing /usr/bin/boinc_client "open" access to device nvidiactl.

Detailed Description:

[boinc_client has a permissive type (boinc_t). This access was not denied.]

SELinux has denied boinc_client "open" access to device nvidiactl. nvidiactl is
mislabeled, this device has the default label of the /dev directory, which
should not happen. All Character and/or Block Devices should have a label. You
can attempt to change the label of the file using restorecon -v 'nvidiactl'. If
this device remains labeled device_t, then this is a bug in SELinux policy.
Please file a bg report. If you look at the other similar devices labels, ls -lZ
/dev/SIMILAR, and find a type that would work for nvidiactl, you can use chcon
-t SIMILAR_TYPE 'nvidiactl', If this fixes the problem, you can make this
permanent by executing semanage fcontext -a -t SIMILAR_TYPE 'nvidiactl' If the
restorecon changes the context, this indicates that the application that created
the device, created it without using SELinux APIs. If you can figure out which
application created the device, please file a bug report against this
application.

Allowing Access:

Attempt restorecon -v 'nvidiactl' or chcon -t SIMILAR_TYPE 'nvidiactl'
