> Mar 13 19:32:20 DXi5500-12345 kernel: RPC: transport
> (2/17) not supported

After looking at the code (include/linux/socket.h):
#define AF_INET         2       /* Internet IP
Protocol         */

include/linux/in.h:
  IPPROTO_UDP = 17,             /* User Datagram
Protocol               */

Why 2/17 (which is AF_INET/IPPROTO_UDP) not 
registered ?

Looking at the register code: net/sunrpc/xprtsock.c:
static int __init init_xs_transport(void)
{
        xprt_register(&xs_udp4_type);
#if defined(CONFIG_IPV6) ||
defined(CONFIG_IPV6_MODULE)
        xprt_register(&xs_udp6_type);
#endif
        xprt_register(&xs_tcp4_type);
#if defined(CONFIG_IPV6) ||
defined(CONFIG_IPV6_MODULE)
        xprt_register(&xs_tcp6_type);
}

The above code must add to "xprt_list". Note that,
I configured my kernel with CONFIG_IPV6.

Re: nfs over ipv6 support

[Chuck Lever]

Rajesham-

IPv6 is not supported for NFS.  The code you are looking at is a  
development snapshot.

Re: nfs over ipv6 support

[Rajesham Gajjela]

Thanks Chuck for the quick reply.
 - this support is not there even in latest
   kernels (2.6.24 and such) ?
 - Whats is your plan on this ? Do you think,
   it can be done any time soon ?

IPv6 support in Linux NFS is not complete even in the latest upstream  
kernels, although more of it has been filled in than existed in the  
2.6.12 patches.

I gave a short presentation at LSF '08 a couple of weeks ago  
describing progress and plans:

   http://oss.oracle.com/~cel/LSF-08-NFS-IPv6.pdf

The slides are rather sparse, but there was hand waving that went  
with the slides.

nfs over ipv6 support

[Rajesham Gajjela]

Did any body test nfs (v2 and v3) over ipv6 ?
do you guys claim "this feature suppose to work" ?

It did not work for me. Here are the details of
experiments I did (for me server and client is
same):
 
1) Kernel side : Linux-2.6.12-5 +
      linux-2.6.12-rc6-CITI_NFS4_ALL-1.dif +
      Chuck Lever Transport Patch
(http://oss.oracle.com/~cel/linux-2.6/2.6.12/release-notes.html)

2) User land (tools) side: libtirpc-0.1.7-1 + 
     rpcbind-0.1.4 + nfs-utils-1.1.1 + quota-3.12-5
(Ref:
http://nfsv4.bullopensource.org/patches/nfsv4_ipv6-2)

3) rpcbind suppose to recognize ipv6/ipv4 tcp/udp 
   protocols (after modifying /etc/netconfig). I did 
   softlink of /usr/bin/rpcbind to /sbin/portmap).
   Then did "service portmap restart".
   Then "service nfs restart". NFS services failed.

syslog messages:

Mar 13 19:32:20 DXi5500-12345 nfs: Starting NFS
services:  succeeded
