For NFSv4 mounts, the clientaddr= mount option has always been required. Now we have rpc_localaddr() in the kernel, which was modeled after the same logic in the mount.nfs command that constructs the clientaddr= mount option. If user space doesn't provide a clientaddr= mount option, the kernel can now construct its own.

This patch splits global list of NFS servers into per-net-ns array of lists. This looks more strict and clearer. BTW, this patch also makes "/proc/fs/nfsfs/volumes" content depends on /proc mount owner pid namespace. See below for details. NOTE: few words about how was /proc/fs/nfsfs/ entries content show per network namespace done. This is a little bit tricky and not the best is could be. But it's cheap (proper fix for /proc conteinerization is a hard nut to crack). The idea is simple: take proper network namespace from pid namespace child reaper nsproxy of /proc/ mount creator. This actually means, that if there are 2 containers with different net namespace sharing pid namespace, then read of /proc/fs/nfsfs/ entries will always return content, taken from net namespace of pid namespace creator task (and thus second namespace set wil be unvisible).

v2: 1) Added "nfs_idmap_init" and "nfs_idmap_quit" definitions for kernels built without CONFIG_NFS_V4 option set. This patch subscribes NFS clients to RPC pipefs notifications. Idmap notifier is registering on NFS module load. This notifier callback is responsible for creation/destruction of PipeFS idmap pipe dentry for NFS4 clients. Since ipdmap pipe is created in rpc client pipefs directory, we have make sure, that this directory has been created already. IOW RPC client notifier callback has been called already. To achive this, PipeFS notifier priorities has been introduced (RPC clients notifier priority is greater than NFS idmap one). But this approach gives another problem: unlink for RPC client directory will be called before NFS idmap pipe unlink on UMOUNT event and will fail, because directory is not empty. The solution, introduced in this patch, is to try to remove client directory once again after idmap pipe was unlinked. This looks like ugly hack, so probably it should be replaced in some more elegant way. Note that no locking required in notifier callback because PipeFS superblock pointer is passed as an argument from it's creation or destruction routine and thus we can be sure about it's validity.

Now that the use of numeric uids/gids is officially sanctioned in RFC3530bis, it is time to change the default here to 'enabled'. By doing so, we ensure that NFSv4 copies the behaviour of NFSv3 when we're using the default AUTH_SYS authentication (i.e. when the client uses the numeric uids/gids as authentication tokens), so that when new files are created, they will appear to have the correct user/group. It also fixes a number of backward compatibility issues when migrating from NFSv3 to NFSv4 on a platform where the server uses different uid/gid mappings than the client. Note also that this setting has been successfully tested against servers that do not support numeric uids/gids at several Connectathon/Bakeathon events at this point, and the fall back to using string names/groups has been shown to work well in all those test cases.

Servers have a finite amount of memory to store NFSv4 open and lock owners. Moreover, servers may have a difficult time determining when they can reap their state owner table, thanks to gray areas in the NFSv4 protocol specification. Thus clients should be careful to reuse state owners when possible. Currently Linux is not too careful. When a user has closed all her files on one mount point, the state owner's reference count goes to zero, and it is released. The next OPEN allocates a new one. A workload that serially opens and closes files can run through a large number of open owners this way. When a state owner's reference count goes to zero, slap it onto a free list for that nfs_server, with an expiry time. Garbage collect before looking for a state owner. This makes state owners for active users available for re-use. Now that there can be unused state owners remaining at umount time, purge the state owner free list when a server is destroyed. Also be sure not to reclaim unused state owners during state recovery. This change has benefits for the client as well. For some workloads, this approach drops the number of OPEN_CONFIRM calls from the same as the number of OPEN calls, down to just one. This reduces wire traffic and thus open(2) latency. Before this patch, untarring a kernel source tarball shows the OPEN_CONFIRM call counter steadily increasing through the test. With the patch, the OPEN_CONFIRM count remains at 1 throughout the entire untar. As long as the expiry time is kept short, I don't think garbage collection should be terribly expensive, although it does bounce the clp->cl_lock around a bit.
