I think Tom's changelog is misleading. The problem is that the RDMA transport actually does support IPv6, but it doesn't support the IPV6ONLY option yet. So if NFS/RDMA binds to a port for IPv4, then the IPv6 bind fails because of the port collision. Implementing the IPV6ONLY option for RDMA binding is probably not feasible for 2.6.34, so the best band-aid for now seems to be Tom's patch. - R. -- Roland Dreier <[email protected]> || For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/index.html -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
