Re: [PATCH] multipath routing algorithm, better patch

Multiple algorithms can be compiled in at once, so this patch is wrong.
mp_alg is supplied by userspace:

        if (rta->rta_mp_alg) {
                mp_alg = *rta->rta_mp_alg;

                if (mp_alg < IP_MP_ALG_NONE ||
                    mp_alg > IP_MP_ALG_MAX)
                        goto err_inval;
        }

If it isn't set correctly its an iproute problem. Did you actually
experience any problems?

Well, my patch for iproute2 to enable multipath algorithm selection
is currently being merged to Stephen together with the ematch bits.
We had to work out a dependency on GNU flex first (the berkley
version uses the same executable names) so the inclusion was
delayed a bit.
