RPC/RDMA: harden connection logic against missing/late rdma_cm upcalls.

2008-10-10T19:13:31+00:00

Add defensive timeouts to wait_for_completion() calls in RDMA address resolution, and make them interruptible. Fix the timeout units to milliseconds (formerly jiffies) and move to private header. Signed-off-by: Tom Talpey Signed-off-by: Trond Myklebust

svcrdma: Modify the RPC recv path to use FRMR when available

2008-10-06T19:46:01+00:00

RPCRDMA requests that specify a read-list are fetched with RDMA_READ. Using an FRMR to map the data sink improves NFSRDMA security on transports that place the RDMA_READ data sink LKEY on the wire because the valid lifetime of the MR is only the duration of the RDMA_READ. The LKEY is invalidated when the last RDMA_READ WR completes. Mapping the data sink also allows for very large amounts to data to be fetched with a single WR, so if the client is also using FRMR, the entire RPC read-list can be fetched with a single WR.

svcrdma: Add a service to register a Fast Reg MR with the device

2008-10-06T19:45:49+00:00

Fast Reg MR introduces a new WR type. Add a service to register the region with the adapter and update the completion handling to support completions with a NULL WR context. Signed-off-by: Tom Tucker

svcrdma: Add FRMR get/put services

2008-10-06T19:45:18+00:00

Add services for the allocating, freeing, and unmapping Fast Reg MR. These services will be used by the transport connection setup, send and receive routines. Signed-off-by: Tom Tucker

NLM: Remove unused argument from svc_addsock() function

2008-10-04T21:12:27+00:00

Clean up: The svc_addsock() function no longer uses its "proto" argument, so remove it. Signed-off-by: Chuck Lever Cc: Neil Brown Signed-off-by: J. Bruce Fields

svcrdma: Add Fast Reg MR Data Types

2008-10-03T20:39:58+00:00

Add data types to track Fast Reg Memory Regions. The core data type is svc_rdma_fastreg_mr that associates a device MR with a host kva and page list. A field is added to the WR context to keep track of the FRMR used to map the local memory for an RPC. An FRMR list and spin lock are added to the transport instance to keep track of all FRMR allocated for the transport. Also added are device capability flags to indicate what the memory registration capabilities are for the underlying device and whether or not fast memory registration is supported.

nfsd: use nfs client rpc callback program

2008-09-29T22:13:40+00:00

since commit ff7d9756b501744540be65e172d27ee321d86103 "nfsd: use static memory for callback program and stats" do_probe_callback uses a static callback program (NFS4_CALLBACK) rather than the one set in clp->cl_callback.cb_prog as passed in by the client in setclientid (4.0) or create_session (4.1). This patches introduces rpc_create_args.prognumber that allows overriding program->number when creating rpc_clnt. Signed-off-by: Benny Halevy Signed-off-by: J. Bruce Fields
