The authentication can be circumvented, by design, by using the render node.
From the driver POV there is no distinction between primary and render nodes, thus we can drop the token.
Note: the outstanding DRM_AUTH instances are:
- legacy DRI1 ioctls, which are already neutered
- modern but deprecated ioctls

drm/i915: remove DRM_AUTH from IOCTLs which also have DRM_RENDER_ALLOWIt's headed to drm-next in [1].
Right my series is based on drm-misc-next, which does not (yet) have the patch. I'll drop my patch when the equivalent, shows up in drm-misc-next.
Thanks Emil
