With the previous patch drm_crtc_find will return NULL when the crtc isn't in our lease, which will then disable the plane/connector. No longer an issue since the lessor can't escape their lease terms anymore, but not quite great semantics yet either. Catch this and return -EACCES, so that at least evil test cases have a better chance of making sure the kernel works correctly. Reviewed-by:

We need this to make sure lessees can only connect their plane/connectors to crtc objects they own. And note that this is irrespective of whether the lessor is atomic or not, lessor cannot prevent lessees from enabling atomic.

If userspace doesn't enable universal planes, then we automatically add the primary and cursor planes. But for universal userspace there's no such check (and maybe we only want to give the lessee one plane, maybe not even the primary one), hence we need to check for the implied plane. v2: don't forget setcrtc ioctl. v3: Still allow disabling of the crtc in SETCRTC.

Not exactly sure what's the aim here, but the canonical nil object has id == 0, we don't use negative object ids for anything. Plus all object_id are valided by the object_idr, there's nothing we need to do on top of that ENOENT check a bit further down.

There was a nouveau DDX that relied on legacy context ioctls to work, but we fixed it years ago, give distros that have a modern DDX the option to break the uAPI and close the mess of holes that legacy context support is. Full context of the story: commit 0e975980 Author: Peter Antoine <peter.antoine@intel.com> Date: Tue Jun 23 08:18:49 2015 +0100 drm: Turn off Legacy Context Functions The context functions are not used by the i915 driver and should not be used by modeset drivers. These driver functions contain several bugs and security holes. This change makes these functions optional can be turned on by a setting, they are turned off by default for modeset driver with the exception of the nouvea driver that may require them with an old version of libdrm. The previous attempt was commit 7c510133 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Thu Aug 8 15:41:21 2013 +0200 drm: mark context support as a legacy subsystem but this had to be reverted commit c21eb21c Author: Dave Airlie <airlied@redhat.com> Date: Fri Sep 20 08:32:59 2013 +1000 Revert "drm: mark context support as a legacy subsystem" v2: remove returns from void function, and formatting (Daniel Vetter) v3: - s/Nova/nouveau/ in the commit message, and add references to the previous attempts - drop the part touching the drm hw lock, that should be a separate patch.
