| * drm/ttm, drm/vmwgfx: Relax permission checking when opening surfacesThomas Hellstrom2017-03-301-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, when a surface was opened using a legacy (non prime) handle, it was verified to have been created by a client in the same master realm. Relax this so that opening is also allowed recursively if the client already has the surface open. This works around a regression in svga mesa where opening of a shared surface is used recursively to obtain surface information.

* drm/vmwgfx: Fix up user_dmabuf refcountingThomas Hellstrom2015-09-141-8/+21
| | | | | | | | | | | | | | | | | | | If user space calls unreference on a user_dmabuf it will typically kill the struct ttm_base_object member which is responsible for the user-space visibility. However the dmabuf part may still be alive and refcounted. In some situations, like for shared guest-backed surface referencing/opening, the driver may try to reference the struct ttm_base_object member again, causing an immediate kernel warning and a later kernel NULL pointer dereference. Fix this by always maintaining a reference on the struct ttm_base_object member, in situations where it might subsequently be referenced.

In this case, the DMA buf can be pinned as the display surface, saving an extra copy.

Since this buffer can only be reserved by the process holding the surface reservation or by the buffer eviction processes that use tryreserve, there is no real deadlock here, but there's no other way to silence lockdep than to use a tryreserve.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use the new vma-manager infrastructure. This doesn't change any implementation details as the vma-offset-manager is nearly copied 1-to-1 from TTM. The vm_lock is moved into the offset manager so we can drop it from TTM. During lookup, we use the vma locking helpers to take a reference to the found object. In all other scenarios, locking stays the same as before. We always guarantee that drm_vma_offset_remove() is called only during destruction. Hence, helpers like drm_vma_node_offset_addr() are always safe as long as the node has a valid offset. This also drops the addr_space_offset member as it is a copy of vm_start in vma_node objects. Use the accessor functions instead. v4: - remove vm_lock - use drm_vma_offset_lock_lookup() to protect lookup (instead of vm_lock) Cc: Dave Airlie <airlied@redhat.com> Cc: Ben Skeggs <bskeggs@redhat.com> Cc: Maarten Lankhorst <maarten.lankhorst@canonical.com> Cc: Martin Peres <martin.peres@labri.fr> Cc: Alex Deucher <alexander.deucher@amd.com> Cc: Thomas Hellstrom <thellstrom@vmware.com> Signed-off-by: David Herrmann <dh.herrmann@gmail.com> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Dave Airlie <airlied@gmail.com>
