Nice work! After a quick look at this (I'll go through it in more detail
later), it looks like I can use the core parts of this for Babel as
well. :)

It looks like a separate channel is needed for SADR routes; (right?) but
can SADR and non-SADR ipv6 routes co-exist in the same FIB?

Yes, they can. You can use two kernel protocols, one with the SADR channel
 and the other with ipv6. Both sets of routes are stored in the same kernel
table.


But the kernel bug is still present. Using both types of routes in the same
table gives undefined behavior. A hacky workaround would be to replace ::/0
sources with 2000::/3 in netlink, but it would reduce the set of accepted
prefixes.
