It is not DHCP that concerns me, it is the fact we can't combine net namespaces, RDMA-CM and duplicate GUID IPoIB children together without adding hacks to the kernel. Searching netdevs by IP is a hack. I'm mostly fine with it as an optional capability, similar to macvlan, I just don't see how to cleanly integrate it with RDMA CM and namespaces. And I don't see what RDMA CM is supposed to do when it hits this case. So, any ideas that don't involve the searching for IP hack?? [And yes, as discussed with Haggie, it is not the worst hack in the world, and maybe we can live with it, but lets understand the trade offs carefully] Also, now that this has been brought up, I think you need to make a patch to fix the IPv6 SLAAC breakage this caused. It looks trivial to modify addrconf_ifid_infiniband to return error if the IPoIB child is sharing a guid. It was not good at all to push the child patches forward to 3.6/3.7 if you knew that IPv6 SLAAC was broken by them.
