SUNRPC: Don't wake tasks during connection abort

2014-11-14T18:10:22Z

commit a743419f420a64d442280845c0377a915b76644f upstream. When aborting a connection to preserve source ports, don't wake the task in xs_error_report. This allows tasks with RPC_TASK_SOFTCONN to succeed if the connection needs to be re-established since it preserves the task's status instead of setting it to the status of the aborting kernel_connect(). This may also avoid a potential conflict on the socket's lock. Signed-off-by: Benjamin Coddington Signed-off-by: Trond Myklebust Signed-off-by: Greg Kroah-Hartman

Pull NFS client updates from Trond Myklebust: "Highlights include: - massive cleanup of the NFS read/write code by Anna and Dros - support multiple NFS read/write requests per page in order to deal with non-page aligned pNFS striping. Also cleans up the r/wsize < page size code nicely. - stable fix for ensuring inode is declared uptodate only after all the attributes have been checked. - stable fix for a kernel Oops when remounting - NFS over RDMA client fixes - move the pNFS files layout driver into its own subdirectory" * tag 'nfs-for-3.16-1' of git://git.linux-nfs.org/projects/trondmy/linux-nfs: (79 commits) NFS: populate ->net in mount data when remounting pnfs: fix lockup caused by pnfs_generic_pg_test NFSv4.1: Fix typo in dprintk NFSv4.1: Comment is now wrong and redundant to code NFS: Use raw_write_seqcount_begin/end int nfs4_reclaim_open_state xprtrdma: Disconnect on registration failure xprtrdma: Remove BUG_ON() call sites xprtrdma: Avoid deadlock when credit window is reset SUNRPC: Move congestion window constants to header file xprtrdma: Reset connection timeout after successful reconnect xprtrdma: Use macros for reconnection timeout constants xprtrdma: Allocate missing pagelist xprtrdma: Remove Tavor MTU setting xprtrdma: Ensure ia->ri_id->qp is not NULL when reconnecting xprtrdma: Reduce the number of hardway buffer allocations xprtrdma: Limit work done by completion handler xprtrmda: Reduce calls to ib_poll_cq() in completion handlers xprtrmda: Reduce lock contention in completion handlers xprtrdma: Split the completion queue xprtrdma: Make rpcrdma_ep_destroy() return void ...

SUNRPC: allow disabling idle timeout

2013-04-26T15:41:26Z

In the gss-proxy case we don't want to have to reconnect at random--we want to connect only on gss-proxy startup when we can steal gss-proxy's context to do the connect in the right namespace. So, provide a flag that allows the rpc_create caller to turn off the idle timeout. Signed-off-by: J. Bruce Fields

SUNRPC: Allow rpc_create() to request that TCP slots be unlimited

2013-04-14T16:26:03Z

This is mainly for use by NFSv4.1, where the session negotiation ultimately wants to decide how many RPC slots we can fill. Signed-off-by: Trond Myklebust

SUNRPC: Fix a livelock problem in the xprt->backlog queue

2013-04-14T16:26:02Z

This patch ensures that we throttle new RPC requests if there are requests already waiting in the xprt->backlog queue. The reason for doing this is to fix livelock issues that can occur when an existing (high priority) task is waiting in the backlog queue, gets woken up by xprt_free_slot(), but a new task then steals the slot.
