The handling of q->plane_sizes was wrong in vb2_core_create_bufs(). The q->plane_sizes array was global and it was overwritten by create_bufs. So if reqbufs was called with e.g. size 100000 then q->plane_sizes[0] would be set to 100000. If create_bufs was called afterwards with size 200000, then q->plane_sizes[0] would be overwritten with the new value. Calling create_bufs again for size 100000 would cause an error since 100000 is now less than q->plane_sizes[0]. This patch fixes this problem by 1) removing q->plane_sizes and using the vb->planes[].length field instead, and 2) by introducing a min_length field in struct vb2_plane. This field is set to the plane size as returned by the queue_setup op and is the minimum required plane size. So user pointers or dmabufs should all be at least this size.
