NFSv4

[Jim Rees]

You may have noticed that there is now an NFS v4 client in the kernel.  It
was written at the Center for Information Technology Integration at the
University of Michigan by me and several others.  I would welcome any
comments, questions, or suggestions you might have.

Unfortunately, servers are hard to come by.  There is no FreeBSD server.
There is a server in linux 2.6, and one in the Network Appliance filer.
There is one available for OpenBSD 2.8.  Hummingbird has one for Windows.

Things I'll be working on in the next few days:

- man pages for idmapd and mount_nfs4
- make it possible to build a v4 module separate from v3

Right now there is no security, but it will be coming soon.  NFSv4 uses
gss-rpc, with kerberos and lipkey (spkm) mechanisms.
