--- Comment #3 from John Baldwin <jhb@FreeBSD.org> ---
BTW, we don't perform any MAC on data read from a GELI volume, this patch would
just ensure we get the right key to decrypt the data.  This is not fully ideal
but is "ok" for a read-only boot loader.  However, GELI has gained write
support in the boot loader at some point and we need to reject writes on a
volume with auth support unless we implement proper auth support in geliboot.
