Pull nfsd changes from J Bruce Fields: "Miscellaneous bugfixes, plus: - An overhaul of the DRC cache by Jeff Layton. The main effect is just to make it larger. This decreases the chances of intermittent errors especially in the UDP case. But we'll need to watch for any reports of performance regressions. - Containerized nfsd: with some limitations, we now support per-container nfs-service, thanks to extensive work from Stanislav Kinsbursky over the last year." Some notes about conflicts, since there were *two* non-data semantic conflicts here: - idr_remove_all() had been added by a memory leak fix, but has since become deprecated since idr_destroy() does it for us now. - xs_local_connect() had been added by this branch to make AF_LOCAL connections be synchronous, but in the meantime Trond had changed the calling convention in order to avoid a RCU dereference. There were a couple of more obvious actual source-level conflicts due to the hlist traversal changes and one just due to code changes next to each other, but those were trivial. * 'for-3.9' of git://linux-nfs.org/~bfields/linux: (49 commits) SUNRPC: make AF_LOCAL connect synchronous nfsd: fix compiler warning about ambiguous types in nfsd_cache_csum svcrpc: fix rpc server shutdown races svcrpc: make svc_age_temp_xprts enqueue under sv_lock lockd: nlmclnt_reclaim(): avoid stack overflow nfsd: enable NFSv4 state in containers nfsd: disable usermode helper client tracker in container nfsd: use proper net while reading "exports" file nfsd: containerize NFSd filesystem nfsd: fix comments on nfsd_cache_lookup SUNRPC: move cache_detail->cache_request callback call to cache_read() SUNRPC: remove "cache_request" argument in sunrpc_cache_pipe_upcall() function SUNRPC: rework cache upcall logic SUNRPC: introduce cache_detail->cache_request callback NFS: simplify and clean cache library NFS: use SUNRPC cache creation and destruction helper for DNS cache nfsd4: free_stid can be static nfsd: keep a checksum of the first 256 bytes of request sunrpc: trim off trailing checksum before returning decrypted or integrity authenticated buffer sunrpc: fix comment in struct xdr_buf definition ...

2013-02-28NFSv4.1: LAYOUTGET EDELAY loops timeout to the MDSWeston Andros Adamson
The client will currently try LAYOUTGETs forever if a server is returning NFS4ERR_LAYOUTTRYLATER or NFS4ERR_RECALLCONFLICT - even if the client no longer needs the layout (ie process killed, unmounted). This patch uses the DS timeout value (module parameter 'dataserver_timeo' via rpc layer) to set an upper limit of how long the client tries LATOUTGETs in this situation. Once the timeout is reached, IO is redirected to the MDS. This also changes how the client checks if a layout is on the clp list to avoid a double list_add.

2013-02-28PNFS: set the default DS timeout to 60 secondsWeston Andros Adamson
The client should have 60 second default timeouts for DS operations, not 6 seconds.

Fix memory leak in phy_device_free() for the case when phy_device* returned by phy_device_create() is not registered in the system. Bug description: phy_device_create() sets name of kobject using dev_set_name(), which allocates memory using kvasprintf(), but this memory isn't freed if the underlying device isn't registered properly, because kobject_cleanup() is not called in that case. This can happen (and actually is happening on our machines) if phy_device_register(), called by mdiobus_scan(), fails.

2013-02-28tcp: avoid wakeups for pure ACKEric Dumazet
TCP prequeue mechanism purpose is to let incoming packets being processed by the thread currently blocked in tcp_recvmsg(), instead of behalf of the softirq handler, to better adapt flow control on receiver host capacity to schedule the consumer. But in typical request/answer workloads, we send request, then block to receive the answer. And before the actual answer, TCP stack receives the ACK packets acknowledging the request. Processing pure ACK on behalf of the thread blocked in tcp_recvmsg() is a waste of resources, as thread has to immediately sleep again because it got no payload. This patch avoids the extra context switches and scheduler overhead.

2013-02-28Merge branch 'sctp'David S. Miller
Lee A. Roberts says: ==================== This series of patches resolves several SCTP association hangs observed during SCTP stress testing. Observable symptoms include communications hangs with data being held in the association reassembly and/or lobby (ordering) queues. Close examination of reassembly/ordering queues may show either duplicated or missing packets. In version #2, corrected build failure in initial version of patch series due to wrong calling sequence for sctp_ulpq_partial_delivery() being inserted in sctp_ulpq_renege(). In version #3, adjusted patch documentation to be less repetitive. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2013-02-28sctp: fix association hangs due to partial delivery errorsLee A. Roberts
In sctp_ulpq_tail_data(), use return values 0,1 to indicate whether a complete event (with MSG_EOR set) was delivered. A return value of -ENOMEM continues to indicate an out-of-memory condition was encountered. In sctp_ulpq_retrieve_partial() and sctp_ulpq_retrieve_first(), correct message reassembly logic for SCTP partial delivery. Change logic to ensure that as much data as possible is sent with the initial partial delivery and that following partial deliveries contain all available data. In sctp_ulpq_partial_delivery(), attempt partial delivery only if the data on the head of the reassembly queue is at or before the cumulative TSN ACK point. In sctp_ulpq_renege(), use the modified return values from sctp_ulpq_tail_data() to choose whether to attempt partial delivery or to attempt to drain the reassembly queue as a means to reduce memory pressure. Remove call to sctp_tsnmap_mark(), as this is handled correctly in call to sctp_ulpq_tail_data(). Signed-off-by: Lee A.

Dave pointed out that he saw messages from btrfs although there was no such filesystem on his computers. The automatic device scan is called on every new blockdevice if the usual distro udev rule set is used. The printk introduced in 6f60cbd3ae442c was a remainder from copying portions of code from btrfs_get_bdev_and_sb which is used under different conditions and the warning makes sense there.

2013-02-28Btrfs: fix NULL pointer after aborting a transactionLiu Bo
While doing cleanup work on an aborted transaction, we've set the global running transaction pointer to NULL _before_ waiting all other transaction handles to finish, so others'd hit NULL pointer crash when referencing the global running transaction pointer. This first sets a hint to avoid new transaction handle joining, then waits other existing handles to abort or finish so that we can safely set the above global pointer to NULL.

2013-02-28Btrfs: fix memory leak of log rootsLiu Bo
When we abort a transaction while fsyncing, we'll skip freeing log roots part of committing a transaction, which leads to memory leak. This adds a 'free log roots' in putting super when no more users hold references on log roots, so it's safe and clean.

2013-02-28Btrfs: copy everything if we've created an inline extentJosef Bacik
I noticed while looking into a tree logging bug that we aren't logging inline extents properly. Since this requires copying and it shouldn't happen too often just force us to copy everything for the inode into the tree log when we have an inline extent. With this patch we have valid data after a crash when we write an inline extent. Thanks, Cc: stable@vger.kernel.org Signed-off-by: Josef Bacik <jbacik@fusionio.com>
