Here's a second pass at adding support for NFSv4 callback channels over IPv6. The main changes since the last set are: 1) rebase to Bruce's master/for-2.6.31 branches. It applies cleanly to either. 2) cleaned up the IPv6-enablement patch: mostly this was done by removing conditional compilation from several places where it wasn't really required. 3) add patch that makes it set the sin6_scope_id for the callback address to the same value as the sin6_scope_id in the svc_rqst->rq_addr. This allows the server to call back clients that mounted the server via one of its link-local addresses. Again, tested using opensolaris and linux clients and watching the traffic with wireshark. Everything seems to work. Delegations and recalls work fine to opensolaris. I seem to be having some trouble getting the server to issue delegations to linux clients, but I can see the callback channel being correctly established. I think the problem with delegations is unrelated to this set. It seems to still be a problem even with IPv4 on an unpatched kernel. I think it has something to do with how linux clients are generating open_owner ID's. I'll email the list separately about that...
