copy_to_user() copies the struct the pointer is pointing to, but the length check compares against sizeof(pointer) and not sizeof(struct). On 32-bit the size is probably the same, so it might have worked accidentally. Signed-off-by: Matthias Rosenfelder <mrosenfelder.lkml@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
