2012-03-20SUNRPC/NFS: Add Kbuild dependencies for NFS_DEBUG/RPC_DEBUGTrond Myklebust
This allows us to turn on/off the dprintk() debugging interfaces for those distributions that don't ship the 'rpcdebug' utility. It also allows us to add Kbuild dependencies. Specifically, we already know that dprintk() in general relies on CONFIG_SYSCTL. Now it turns out that the NFS dprintks depend on CONFIG_CRC32 after we added support for the filehandle hash.

2012-03-02SUNRPC: Add API to acquire source addressChuck Lever
NFSv4.0 clients must send endpoint information for their callback service to NFSv4.0 servers during their first contact with a server. Traditionally on Linux, user space provides the callback endpoint IP address via the "clientaddr=" mount option. During an NFSv4 migration event, it is possible that an FSID may be migrated to a destination server that is accessible via a different source IP address than the source server was. The client must update callback endpoint information on the destination server so that it can maintain leases and allow delegation. Without a new "clientaddr=" option from user space, however, the kernel itself must construct an appropriate IP address for the callback update. Provide an API in the RPC client for upper layer RPC consumers to acquire a source address for a remote. The mechanism used by the mount.nfs command is copied: set up a connected UDP socket to the designated remote, then scrape the source address off the socket. We are careful to select the correct network namespace when setting up the temporary UDP socket.

A migration event will replace the rpc_xprt used by an rpc_clnt. To ensure this can be done safely, all references to cl_xprt must now use a form of rcu_dereference(). Special care is taken with rpc_peeraddr2str(), which returns a pointer to memory whose lifetime is the same as the rpc_xprt.

2012-02-27SUNRPC: move waitq from RPC pipe to RPC inodeStanislav Kinsbursky
Currently, wait queue, used for polling of RPC pipe changes from user-space, is a part of RPC pipe. But the pipe data itself can be released on NFS umount prior to dentry-inode pair, connected to it (is case of this pair is open by some process). This is not a problem for almost all pipe users, because all PipeFS file operations checks pipe reference prior to using it. Except evenfd. This thing registers itself with "poll" file operation and thus has a reference to pipe wait queue. This leads to oopses on destroying eventfd after NFS umount (like rpc_idmapd do) since not pipe data left to the point already. The solution is to wait queue from pipe data to internal RPC inode data. This looks more logical, because this wiat queue used only for user-space processes, which already holds inode reference. Note: upcalls have to get pipe->dentry prior to dereferecing wait queue to make sure, that mount point won't disappear from underneath us.

2012-02-17svcrdma: Cleanup sparse warnings in the svcrdma moduleTom Tucker
The svcrdma transport was un-marshalling requests in-place. This resulted in sparse warnings due to __beXX data containing both NBO and HBO data. The code has been restructured to do byte-swapping as the header is parsed instead of when the header is validated immediately after receipt.

2012-02-16SUNRPC: Use KERN_DEFAULT for debugging printk'sChuck Lever
Our dprintk() debugging facility doesn't specify any verbosity level for it's printk() calls, but it should. The default verbosity for printk's is KERN_DEFAULT. You might argue that these are debugging printk's and thus the verbosity should be KERN_DEBUG. That would mean that to see NFS and SUNRPC debugging output an admin would also have to boost the syslog verbosity, which would be insufferably noisy.

2012-02-16SUNRPC: add sending,pending queue and max slot to xprt statsAndy Adamson
With static RPC slots, the xprt backlog queue stats were useful in showing when the transport (TCP) was starved by lack of RPC slots. The new dynamic RPC slot code, commit d9ba131d8f58c0d2ff5029e7002ab43f913b36f9, always provides an RPC slot and so only uses the xprt backlog queue when the tcp_max_slot_table_entries value has been hit or when an allocation error occurs. All requests are now placed on the xprt sending or pending queue which need to be monitored for debugging. The max_slot stat shows the maximum number of dynamic RPC slots reached which is useful when debugging performance issues. Add the new fields at the end of the mountstats xprt stanza so that mountstats outputs the previous correct values and ignores the new fields. Bump NFS_IOSTATS_VERS.

2012-02-15Lockd: per-net up and down routines introducedStanislav Kinsbursky
This patch introduces per-net Lockd initialization and destruction routines. The logic is the same as in global Lockd up and down routines. Probably the solution is not the best one. But at least it looks clear. So per-net "up" routine are called only in case of lockd is running already. If per-net resources are not allocated yet, then service is being registered with local portmapper and lockd sockets created. Per-net "down" routine is called on every lockd_down() call in case of global users counter is not zero.

2012-02-15SUNRPC: service destruction in network namespace contextStanislav Kinsbursky
v2: Added comment to BUG_ON's in svc_destroy() to make code looks clearer. This patch introduces network namespace filter for service destruction function. Nothing special here - just do exactly the same operations, but only for tranports in passed networks namespace context. BTW, BUG_ON() checks for empty service transports lists were returned into svc_destroy() function. This is because of swithing generic svc_close_all() to networks namespace dependable svc_close_net().

2012-02-06SUNRPC: Change the default limit to the number of TCP slotsTrond Myklebust
Since the scheme of limiting the number of TCP slots to whatever will fit in the current TCP window seems to be working well (Andy reports getting within 20% of the 'iperf' send performance on a 10GigE link) we should just let that be the default mode of operation.

2012-01-31NFS: idmap PipeFS notifier introducedStanislav Kinsbursky
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.

During per-net pipes creation and destruction we have to make sure, that pipefs sb exists for the whole creation/destruction cycle. This is done by using special mutex which controls pipefs sb reference on network namespace context.

So we actually don't need this pipefs mount point at all if some pipefs lookup method will be provided. IOW, all we really need is just superblock and simple lookup method to find root's child dentry with appropriate name. And this patch introduces this method.
