SUNRPC: Remove TCP client connection reset hack

2015-02-09T02:47:30+00:00

Instead we rely on SO_REUSEPORT to provide the reconnection semantics that we need for NFSv2/v3. Signed-off-by: Trond Myklebust

SUNRPC: Add helpers to prevent socket create from racing

2015-02-09T02:47:29+00:00

The socket lock is currently held by the task that is requesting the connection be established. While that is efficient in the case where the connection happens quickly, it is racy in the case where it doesn't. What we really want is for the connect helper to be able to block access to the socket while it is being set up. This patch does so by arranging to transfer the socket lock from the task that is requesting the connect attempt, and then releasing that lock once everything is done. This scheme also gives us automatic protection against collisions with the RPC close code, so we can kill the cancel_delayed_work_sync() call in xs_close(). Signed-off-by: Trond Myklebust

sunrpc: add a debugfs rpc_xprt directory with an info file in it

2014-11-27T18:14:52+00:00

Add a new directory heirarchy under the debugfs sunrpc/ directory: sunrpc/ rpc_xprt/ / Within that directory, we can put files that give info about the xprts. We do have the (minor) problem that there is no succinct, unique identifier for rpc_xprts. So we generate them synthetically with a static atomic_t counter. For now, this directory just holds an "info" file, but we may add other files to it in the future. Signed-off-by: Jeff Layton Signed-off-by: Trond Myklebust

SUNRPC: Don't wake tasks during connection abort

2014-09-25T03:06:56+00:00

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 Cc: stable@vger.kernel.org # 3.14+ Signed-off-by: Trond Myklebust

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 ...
