Here's a proposal for adding support in mount.nfs for mounting NFSv4 servers over IPv6. It provides mount.nfs4 with the ability to resolve a hostname to an IPv6 address and pass it to the kernel. It can also pass an IPv6 local address via clientaddr=.
Kernel level sunrpc support rpcbind protocol versions 3 and 4 must be enabled via Kconfig. Support for user-space rpcbind operations for IPv6 addresses is not needed with NFSv4, since the kernel handles rpcbind operations for NFS version 4. To support NFS version 2 and 3 mounts over IPv6, user level support for rpcbind versions 3 and 4 will be required. That is currently under development. Unmount support in umount.nfs4 for IPv6 is not needed for NFSv4 since unmounting an nfs4 file system is a local client operation only. This code is untested; it is posted for review only. -- corporate: <chuck dot lever at oracle dot com> - To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
