Did you look at removing this hunk from rt6_fill_node:
if (rt->rt6i_flags & RTF_DYNAMIC)
rtm->rtm_protocol = RTPROT_REDIRECT;
else if (rt->rt6i_flags & RTF_ADDRCONF) {
if (rt->rt6i_flags & (RTF_DEFAULT | RTF_ROUTEINFO))
rtm->rtm_protocol = RTPROT_RA;
else
rtm->rtm_protocol = RTPROT_KERNEL;
}
And have rtm_protocol set properly on the route when it is installed?
