This may be impolitic to say in public, but the transport switch APIs aren't really needed for IPv6. It just seemed easier to apply the IPv6 changes to the transport switch work than the other way around. On the client, we will need IPv6 addressing support from the mount.nfs command through to the network transport implementations. We have pieces of that implemented. The client needs to have NFSv4 callback support and lockd support for IPv6, so we need RPC server support for IPv6 -- that's nearing completion once we have the ip_map cache fixed up to support IPv6 addresses. On the server, we need support for mountd and rpcbind, and support build into the NFS server itself. I understand Bull is still working on the server changes, and SteveD has added rpcbind to Fedora and is making it robust. In addition I think we will need to examine exportfs and anything else on the server side to check for any dependence on address format. To finish, Bull has been testing parts of this work as it has been developed, and will need to continue testing it after it has all been integrated. Interoperability testing between Linux, Solaris, and AIX are on the list. --------------070308040007050906090008 Content-Type: text/x-vcard; charset=utf-8; name="chuck.lever.vcf" Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename="chuck.lever.vcf" begin:vcard fn:Chuck Lever n:Lever;Chuck org:Oracle Corporation;Corporate Architecture: Linux Projects Group adr:;;1015 Granger Avenue;Ann Arbor;MI;48104;USA email;internet:chuck dot lever at nospam oracle dot com title:Principal Member of Staff tel;work:+1 248 614 5091 x-mozilla-html:FALSE version:2.1 end:vcard --------------070308040007050906090008 Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
