NFS mount over IPv6 success

NFS mount over IPv6 success

[Steinar H. Gunderson]

Hi,

I'm sure others have gotten this to work at some point, but it's finally
gotten to the point where I could get it to work myself, so I thought I could
share my success story:

 - Vanilla 2.6.28-rc3 client (2.6.26 also worked, although not with NFSv4)
 - Solaris 10 server
 - libtirpc from git (git://git.infradead.org/~steved/libtirpc.git)
 - IPv6-patched nfs-utils from git
   (git://git.linux-nfs.org/projects/cel/nfs-utils.git)

After recompiling (actually making Debian packages of) the client software,
it was just a matter of mounting. 2.6.26 had some issues with IPv6 address
literals -- only DNS worked -- but 2.6.28-rc3 did both just fine.

I haven't done extensive testing, but this looks pretty good :-) Now I'm just
waiting for the server support to get ready in the same way, and then for
everything to trickle into mainline.

Steinar-

Thanks for testing!

Keep an eye out for IPv6-related patches for nfs-utils.  The key is to  
ensure IPv4 continues to work, especially on Debian which tracks  
upstream nfs-utils closely.

We don't plan to incorporate IPv6-specific patches before upstream does (and
lenny, our upcoming release, is not going to get libtirpc or rpcbind). When
upstream nfs-utils is ready, you can expect us to configure with
--enable-ipv6 pretty quickly, though :-)

I still haven't had any success with nfsd on the server side in Linux; it's a
bit unclear to me what nfs-utils to use in particular.

 Hi,
 There is a prototype nfs-utils package based on nfs-utils-1.1.2 you ca=
n=20
play with at http://nfsv4.bullopensource.org/

Oops.  Sorry, I forgot about that.

I already tried that with the latest git tree from Chuck, but no go
(statd/nfsd didn't register on IPv6 in rpcbind, IIRC).

My nfs-utils doesn't have any of Bull's server-side changes.  It also  
doesn't have an IPv6-enabled rpc.statd yet.

I used Bull's nfs-utils -- the git tree I was referring to was your kernel
tree, not nfs-utils. :-)

Perhaps things would be better if I used Bull's kernel as well, but 2.6.27
has other issues for me, so it's hard to test on my machine.

We need testing to ensure that the latest nfs-utils still works on  
legacy systems, built with --disable-ipv6 and no libtirpc.  So please  
do test my patches and report issues there.

Server side NFS doesn't have any user space IPv6 support yet.  The  
kernel in my tree supports NFSv4 service over IPv6, but I don't think / 
etc/exports supports IPv6 addresses yet.
