IPv6 support for NFS server: download page

Available documentation

Information about IPv6 support for NFSv4 server is available on NFSv4 wiki: http://wiki.linux-nfs.org/index.php/Server_IPv6_support

Work plan is available here.

Kernel patches

• linux-2.6.21-IPv6-01.diff : changing clnt_addr_list field, used by export and nfsctl parts.
• linux-2.6.21-IPv6-02.diff : Modifying nfsctl part. Modifying authentication part. (auth_unix*). Need to add switches INET/INET6.
• linux-2.6.21-IPv6-03.diff : NFSv4 state part. Changing structure when needed.
• linux-2.6.21-IPv6-04.diff : Modyfing cache part. Need to add switches INET/INET6.
• linux-2.6.21-IPv6-05.diff : Lock part: changing INET structure.
• linux-2.6.21-IPv6-06.diff : Changing the svc_auth part.

Required sources

These patches must be applied on:

• 2.6.21 vanilla kernel
• Chuck Lever 2.6.21 Transport Switch patchset: it includes most of the IPv6 support client features, which are partly used by the server part.

Userland part: nfs-utils-1.0.8 "IPv6 ready" package

nfs-utils-1.0.8-rc2-IPv6.tar.bz2 : Standalone tarballs for NFS server userland part. It is based on nfs-utils-1.0.8-rc2 + CITI patches. Port to 1.0.9 coming soon.

Required software

2 packages have to be installed to manage Remote Procedure Calls through IPv6:

• TI-RPC library to replace SunRPC library that is part of glibc.
• RPCBind program, to replace portmapper.

See further information about these 2 components here

Tests (conformance, functional, performance, interoperability):

Each new patch has been tested with NFS mounts over IPv4 to verify that nothing is broken.
The IPv6 tests have been performed with non-Linux IPv6-ready NFSv4 clients. Stress tests have been performed with fstress and fsx. Performance comparison between IPv6 and IPv4 based connections will be soon available.

Reporting troubles

Tests and comments are welcomed. These patches have been tested on ia32 and x86_64 architectures. Testing on other architectures are welcome. Feel free to ask us any question by mail.
