Pull NFS client updates for Linux 3.4 from Trond Myklebust: "New features include: - Add NFS client support for containers. This should enable most of the necessary functionality, including lockd support, and support for rpc.statd, NFSv4 idmapper and RPCSEC_GSS upcalls into the correct network namespace from which the mount system call was issued. - NFSv4 idmapper scalability improvements Base the idmapper cache on the keyring interface to allow concurrent access to idmapper entries. Start the process of migrating users from the single-threaded daemon-based approach to the multi-threaded request-key based approach. - NFSv4.1 implementation id. Allows the NFSv4.1 client and server to mutually identify each other for logging and debugging purposes. - Support the 'vers=4.1' mount option for mounting NFSv4.1 instead of having to use the more counterintuitive 'vers=4,minorversion=1'. - SUNRPC tracepoints. Start the process of adding tracepoints in order to improve debugging of the RPC layer. - pNFS object layout support for autologin. Important bugfixes include: - Fix a bug in rpc_wake_up/rpc_wake_up_status that caused them to fail to wake up all tasks when applied to priority waitqueues. - Ensure that we handle read delegations correctly, when we try to truncate a file. - A number of fixes for NFSv4 state manager loops (mostly to do with delegation recovery)." * tag 'nfs-for-3.4-1' of git://git.linux-nfs.org/projects/trondmy/linux-nfs: (224 commits) NFS: fix sb->s_id in nfs debug prints xprtrdma: Remove assumption that each segment is <= PAGE_SIZE xprtrdma: The transport should not bug-check when a dup reply is received pnfs-obj: autologin: Add support for protocol autologin NFS: Remove nfs4_setup_sequence from generic rename code NFS: Remove nfs4_setup_sequence from generic unlink code NFS: Remove nfs4_setup_sequence from generic read code NFS: Remove nfs4_setup_sequence from generic write code NFS: Fix more NFS debug related build warnings SUNRPC/LOCKD: Fix build warnings when CONFIG_SUNRPC_DEBUG is undefined nfs: non void functions must return a value SUNRPC: Kill compiler warning when RPC_DEBUG is unset SUNRPC/NFS: Add Kbuild dependencies for NFS_DEBUG/RPC_DEBUG NFS: Use cond_resched_lock() to reduce latencies in the commit scans NFSv4: It is not safe to dereference lsp->ls_state in release_lockowner NFS: ncommit count is being double decremented SUNRPC: We must not use list_for_each_entry_safe() in rpc_wake_up() Try using machine credentials for RENEW calls NFSv4.1: Fix a few issues in filelayout_commit_pagelist NFSv4.1: Clean ups and bugfixes for the pNFS read/writeback/commit code ...

2012-01-31SUNRPC: handle RPC client pipefs dentries by network namespace aware routinesStanislav Kinsbursky
v2: 1) "Over-put" of PipeFS mount point fixed. Fix is ugly, but allows to bisect the patch set. And it will be removed later in the series. This patch makes RPC clients PipeFs dentries allocations in it's owner network namespace context. RPC client pipefs dentries creation logic has been changed: 1) Pipefs dentries creation by sb was moved to separated function, which will be used for handling PipeFS mount notification. 2) Initial value of RPC client PipeFS dir dentry is set no NULL now. RPC client pipefs dentries cleanup logic has been changed: 1) Cleanup is done now in separated rpc_remove_pipedir() function, which takes care about pipefs superblock locking. Also this patch removes slashes from cb_program.pipe_dir_name and from NFS_PIPE_DIRNAME to make rpc_d_lookup_sb() work. This doesn't affect vfs_path_lookup() results in nfs4blocklayout_init() since this slash is cutted off anyway in link_path_walk().

2012-01-05NFSD: Change name of extended attribute containing junctionChuck Lever
As of fedfs-utils-0.8.0, user space stores all NFS junction information in a single extended attribute: "trusted.junction.nfs". Both FedFS and NFS basic junctions are stored in this one attribute, and the intention is that all future forms of NFS junction metadata will be stored in this attribute. Other protocols may use a different extended attribute. Thus NFSD needs to look only for that one extended attribute. The "trusted.junction.type" xattr is deprecated. fedfs-utils-0.8.0 will continue to attach a "trusted.junction.type" xattr to junctions, but future fedfs-utils releases may no longer do that.

2012-01-05nfsd4: be forgiving in the absence of the recovery directoryJ. Bruce Fields

2011-11-07nfsd4: hash lockowners to simplify RELEASE_LOCKOWNERJ. Bruce Fields
Hash lockowners on just the owner string rather than on (owner, inode). This makes the owner-string lookup needed for RELEASE_LOCKOWNER simpler (currently it's doing at a linear search through the entire hash table!). That may come at the expense of making (owner, inode) lookups more expensive if a client reuses the same lockowner across multiple files. We might add a separate lookup for that. Signed-off-by: J.

2011-11-07NFSD: Added fault injectionBryan Schumaker
Fault injection on the NFS server makes it easier to test the client's state manager and recovery threads. Simulating errors on the server is easier than finding the right conditions that cause them naturally. This patch uses debugfs to add a simple framework for fault injection to the server. This framework is a config option, and can be enabled through CONFIG_NFSD_FAULT_INJECTION. Assuming you have debugfs mounted to /sys/debug, a set of files will be created in /sys/debug/nfsd/. Writing to any of these files will cause the corresponding action and write a log entry to dmesg. Signed-off-by: Bryan Schumaker <bjschuma@netapp.com> Signed-off-by: J.

2011-10-31fs: add module.h to files that were implicitly using itPaul Gortmaker
Some files were using the complete module.h infrastructure without actually including the header at all. Fix them up in advance so once the implicit presence is removed, we won't get failures like this: CC [M] fs/nfsd/nfssvc.o fs/nfsd/nfssvc.c: In function 'nfsd_create_serv': fs/nfsd/nfssvc.c:335: error: 'THIS_MODULE' undeclared (first use in this function) fs/nfsd/nfssvc.c:335: error: (Each undeclared identifier is reported only once fs/nfsd/nfssvc.c:335: error: for each function it appears in.) fs/nfsd/nfssvc.c: In function 'nfsd': fs/nfsd/nfssvc.c:555: error: implicit declaration of function 'module_put_and_exit' make[3]: *** [fs/nfsd/nfssvc.o] Error 1 Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
2011-10-31fs: add export.h to files using EXPORT_SYMBOL/THIS_MODULE macrosPaul Gortmaker
These files were getting <linux/module.h> via an implicit include path, but we want to crush those out of existence since they cost time during compiles of processing thousands of lines of headers for no reason. Give them the lightweight header that just contains the EXPORT_SYMBOL infrastructure. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
2011-10-25NFSd: call svc rpcbind cleanup explicitlyStanislav Kinsbursky
We have to call svc_rpcb_cleanup() explicitly from nfsd_last_thread() since this function is registered as service shutdown callback and thus nobody else will done it for us. Signed-off-by: Stanislav Kinsbursky <skinsbursky@parallels.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
