Status of NFS over IPv6
Subsystems (2)
Hi,
What's the current status of NFS over IPv6 in Linux? There are HOWTOs out there, but most patches seem to be against old kernel versions, and completely unable to run both client and server from the same kernel tree. Additionally, I see mentions of replacements for portmap, but no clear upstream URL or updated versions anywhere. Also, there seems to be a separate git tree maintained by Chuck Lever, but gitweb hides any special patches it might have in tons of upstream patches.
I'd very much like to be able to sew all of this together at some point, but it's very hard to get a decent overview of it all. Does anyone have a "current status" or "plans for the near feature" summary?

I have some patches that add IPv6 support in the RPC client. The server is more complicated (how to deal with address-based export rules, and so on). There hasn't been much progress on the server side, but I think Bull is still working on that.
There are some patches for the NFS client, but we need to have both RPC client and server support for NFSv4 callback and NLM to work over IPv6 (required for even a complete client implementation).
At this very moment I'm working on implementing mount option parsing in the kernel so we can easily add IPv6 addressing support to the NFS mount interface (among other improvements this will enable).
Steve Dickson has added Bull's rpcbind (replacement for portmap) to Fedora 7, but there is some disagreement about whether to use a complete replacement, like rpcbind, or whether to add the needed support to the existing portmap code, in general.
Bull has announced a test plan for user-space RPC libraries, although I haven't had a moment to look through it. Bull should be providing testing resources once we have all of this integrated.
While there is some interest in IPv6 among some of Linux's corporate sponsors, there really isn't an overwhelming "killer" requirement for IPv6, so there isn't much motivation to get all this completed. I have to admit I'm pretty burned out on all this because of how complicated it has all become. I'd be happy if someone stepped forward and volunteered to help or take over the integration.

OK, and they still conflict?

Well, all I can really provide is a useful test bed inside Debian. I doubt I can get the kernel team to include NFS/IPv6-specific patches, but when it comes to rpcbind, nfs-utils and the like, I'm sure we can work something out. IOW, I don't think I can do much about the programming, but once stuff is "80% there" we can at least provide an environment users can test stuff relatively easy inside. (We already have quite good NFSv4 support out-of-the-box.)

Yeah, it's kind of unfortunate that we can't be completely specific about the requests/requirements/use cases. But here's what I know:
1. Apparently there is a bureaucratic (ie non-technical) requirement from the US Federal government for IPv6 support in new computer software deployments. I forget when this requirement kicks in, or what exactly "IPv6 support" really entails.
2. The APAC market wants IPv6 because of an explosion of individual IP network accessors, although arguably that can be addressed for a little while with judicious application of NAT routers.
Otherwise, the companies I've worked for recently have had no real customer requests for IPv6 support in NFS.
NFS community resources are focused largely on NFSv4.1 and pNFS design and implementation. However, here's some of what I think we need to get IPv6 done:
+ A coherent design for handling IPv6 address caching and export rules on the server side
+ Help from the netdev folks with reviewing our proposed IPv6 changes
+ A cunning plan to stage the integration of all the various pieces
+ Beta testers (ie real environments that can deploy NFS over IPv6 in real conditions)
+ A whiff of project planning to help us know what the real deadlines are

Hi,
Back in 2005, the US Office of Management and Budget (OMB) issued a mandate calling on all Federal Agencies to have an operational IPv6 backbone network by June, 2008. As the date approaches, USG customers are increasingly asking whether individual products/applications are "IPv6 compliant".
The DoD has also indicated that it is developing an Approved Products List (APL) on which certified IPv6 compliant products will be listed. The intention is that any product purchased by the DoD must first be certified and added to the list.
We have some nongovernment customers (names cannot be disclosed) requesting for IPv6 support in NFS, and few of them are willing to participate in pilot program. In addition to the customers, we have some requests from different product owners for this support, so that their products can be made "IPv6 complaint".
