2010-08-17	drm: block userspace under allocating buffer and having drivers overwrite it (v2)	Dave Airlie	1	-4/+4
	With the current screwed but its ABI, ioctls for the drm, Linus pointed out that we could allow userspace to specify the allocation size, but we pass it to the driver which then uses it blindly to store a struct. Now if userspace specifies the allocation size as smaller than the driver needs, the driver can possibly overwrite memory. This patch restructures the driver ioctls so we store the structure size we are expecting, and make sure we allocate at least that size. The copy from/to userspace are still restricted to the size the user specifies, this allows ioctl structs to grow on both sides of the equation. Up until now we didn't really use the DRM_IOCTL defines in the kernel, so this cleans them up and adds them for nouveau. v2: fix nouveau pushbuf arg (thanks to Ben for pointing it out) Reported-by: Linus Torvalds <torvalds@linuxfoundation.org> Signed-off-by: Dave Airlie <airlied@redhat.com>
2008-07-14	drm: reorganise drm tree to be more future proof.	Dave Airlie	1	-0/+210
	With the coming of kernel based modesetting and the memory manager stuff, the everything in one directory approach was getting very ugly and starting to be unmanageable. This restructures the drm along the lines of other kernel components. It creates a drivers/gpu/drm directory and moves the hw drivers into subdirectores. It moves the includes into an include/drm, and sets up the unifdef for the userspace headers we should be exporting. Signed-off-by: Dave Airlie <airlied@redhat.com>
