2012-03-03NFS: Request fh_expire_type attribute in "server caps" operationChuck Lever2-0/+4
The fh_expire_type file attribute is a filesystem wide attribute that consists of flags that indicate what characteristics file handles on this FSID have. Our client doesn't support volatile file handles. It should find out early (say, at mount time) whether the server is going to play shenanighans with file handles during a migration.

2012-03-03NFS: Introduce NFS_ATTR_FATTR_V4_LOCATIONSChuck Lever1-5/+6
The Linux NFS client must distinguish between referral events (which it currently supports) and migration events (which it does not yet support). In both types of events, an fs_locations array is returned. But upper layers, not the XDR layer, should make the distinction between a referral and a migration. There really isn't a way for an XDR decoder function to distinguish the two, in general. Slightly adjust the FATTR flags returned by decode_fs_locations() to set NFS_ATTR_FATTR_V4_LOCATIONS only if a non-empty locations array was returned from the server. Then have logic in nfs4proc.c distinguish whether the locations array is for a referral or something else.

2012-03-03NFS: Add a client-side function to display NFS file handlesChuck Lever1-0/+14
For debugging, introduce a simplistic function to print NFS file handles on the system console. The main function is hooked into the dprintk debugging facility, but you can directly call the helper, _nfs_display_fhandle(), if you want to print a handle unconditionally.

2012-03-03SUNRPC: Add API to acquire source addressChuck Lever1-0/+1
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.

2012-03-03SUNRPC: Move clnt->cl_server into struct rpc_xprtTrond Myklebust2-1/+2

2012-03-03SUNRPC: Use RCU to dereference the rpc_clnt.cl_xprt fieldTrond Myklebust2-1/+16
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.

2012-03-02NFS: Store the legacy idmapper result in the keyringBryan Schumaker1-11/+0
This patch removes the old hashmap-based caching and instead uses a "request key actor" to place an upcall to the legacy idmapper rather than going through /sbin/request-key.

2012-02-27SUNRPC: move waitq from RPC pipe to RPC inodeStanislav Kinsbursky1-1/+1
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.

2012-02-16SUNRPC: Use KERN_DEFAULT for debugging printk'sChuck Lever1-1/+5
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 Adamson2-3/+6
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 Kinsbursky1-0/+2
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 Kinsbursky1-1/+1
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().

2012-02-07NFS: Fall back on old idmapper if request_key() failsBryan Schumaker1-15/+0
This patch removes the CONFIG_NFS_USE_NEW_IDMAPPER compile option. First, the idmapper will attempt to map the id using /sbin/request-key and nfsidmap. If this fails (if /etc/request-key.conf is not configured properly) then the idmapper will call the legacy code to perform the mapping. I left a comment stating where the legacy code begins to make it easier for somebody to remove in the future.

2012-02-07SUNRPC: Change the default limit to the number of TCP slotsTrond Myklebust2-2/+2
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. Users may still set their own limits using the tcp_max_slot_table_entries parameter if they need to. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

2012-02-04NFSv4: Fix an Oops in the NFSv4 getacl codeTrond Myklebust1-1/+1
Commit bf118a342f10dafe44b14451a1392c3254629a1f (NFSv4: include bitmap in nfsv4 get acl data) introduces the 'acl_scratch' page for the case where we may need to decode multi-page data. However it fails to take into account the fact that the variable may be NULL (for the case where we're not doing multi-page decode), and it also attaches it to the encoding xdr_stream rather than the decoding one. The immediate result is an Oops in nfs4_xdr_enc_getacl due to the call to page_address() with a NULL page pointer.

2012-02-01mtd: fix merge conflict resolution breakageArtem Bityutskiy1-1/+1
This patch fixes merge conflict resolution breakage introduced by merge d3712b9dfcf4 ("Merge tag 'for-linus' of git://github.com/prasad-joshi/logfs_upstream"). The commit changed 'mtd_can_have_bb()' function and made it always return zero, which is incorrect. Instead, we need it to return whether the underlying flash device can have bad eraseblocks or not. UBI needs this information because it affects how it handles the underlying flash. E.g., if the underlying flash is NOR, it cannot have bad blocks and any write or erase error is fatal, and all we can do is to switch to R/O mode. We do not need to reserve a pool of good eraseblocks for bad eraseblocks handling, and so on. This patch also removes 'mtd_can_have_bb()' invocations from Logfs to ensure correct Logfs behavior. I've tested that with this patch UBI works on top of NOR and NAND flashes emulated by mtdram and nandsim correspondingly. This patch is based on patch from Linus Torvalds.
