2008-07-15SUNRPC: Remove the BKL from the callback functionsTrond Myklebust
Push it into those callback functions that actually need it. Note that all the NFS operations use their own locking, so don't need the BKL. Ditto for the rpcbind client. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
2008-07-15SUNRPC: Support registering IPv6 interfaces with local rpcbind daemonChuck Lever
Introduce a new API to register RPC services on IPv6 interfaces to allow the NFS server and lockd to advertise on IPv6 networks. Unlike rpcb_register(), the new rpcb_v4_register() function uses rpcbind protocol version 4 to contact the local rpcbind daemon. The version 4 SET/UNSET procedures allow services to register address families besides AF_INET, register at specific network interfaces, and register transport protocols besides UDP and TCP. All of this functionality is exposed via the new rpcb_v4_register() kernel API. A user-space rpcbind daemon implementation that supports version 4 of the rpcbind protocol is required in order to make use of this new API. Note that rpcbind version 3 is sufficient to support the new rpcbind facilities listed above, but most extant implementations use version 4.

2008-07-15SUNRPC: Use correct XDR encoding procedure for rpcbind SET/UNSETChuck Lever
The rpcbind versions 3 and 4 SET and UNSET procedures use the same arguments as the GETADDR procedure. While definitely a bug, this hasn't been a problem so far since the kernel hasn't used version 3 or 4 SET and UNSET. But this will change in just a moment.

2008-07-09SUNRPC: Ensure our task is notified when an rpcbind call is doneTrond Myklebust
If another task is busy in rpcb_getport_async number, it is more efficient to have it wake us up when it has finished instead of arbitrarily sleeping for 5 seconds. Also ensure that rpcb_wake_rpcbind_waiters() is called regardless of whether or not rpcb_getport_done() gets called. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
2008-07-09SUNRPC: Use only rpcbind v2 for AF_INET requestsChuck Lever
Some server vendors support the higher versions of rpcbind only for AF_INET6. The kernel doesn't need to use v3 or v4 for AF_INET anyway, so change the kernel's rpcbind client to query AF_INET servers over rpcbind v2 only. This has a few interesting benefits: 1. If the rpcbind request is going over TCP, and the server doesn't support rpcbind versions 3 or 4, the client reduces by two the number of ephemeral ports left in TIME_WAIT for each rpcbind request. This will help during NFS mount storms. 2. The rpcbind interaction with servers that don't support rpcbind versions 3 or 4 will use less network traffic. Also helpful during mount storms. 3. We can eliminate the kernel build option that controls whether the kernel's rpcbind client uses rpcbind version 3 and 4 for AF_INET servers. Less complicated kernel configuration...

2008-07-09SUNRPC: Use GETADDR for rpcbind version 4 queriesChuck Lever

2008-07-09SUNRPC: Use rpcbind version 2 GETPORTChuck Lever
Clean up: Change the version 2 procedure name to GETPORT. It's the same procedure number as GETADDR, but version 2 implementations usually refer to it as GETPORT. This also now matches the procedure name used in the version 2 procedure entry in the rpcb_next_version[] array, making it slightly less confusing.

2008-07-09SUNRPC: Ensure all transports set rq_xtime consistentlyChuck Lever
The RPC client uses the rq_xtime field in each RPC request to determine the round-trip time of the request. Currently, the rq_xtime field is initialized by each transport just before it starts enqueing a request to be sent. However, transports do not handle initializing this value consistently; sometimes they don't initialize it at all. To make the measurement of request round-trip time consistent for all RPC client transport capabilities, pull rq_xtime initialization into the RPC client's generic transport logic. Now all transports will get a standardized RTT measure automatically, from: xprt_transmit() to xprt_complete_rqst() This makes round-trip time calculation more accurate for the TCP transport. The socket ->sendmsg() method can return "-EAGAIN" if the socket's output buffer is full, so the TCP transport's ->send_request() method may call the ->sendmsg() method repeatedly until it gets all of the request's bytes queued in the socket's buffer. Currently, the TCP transport sets the rq_xtime field every time through that loop so the final value is the timestamp just before the *last* call to the underlying socket's ->sendmsg() method. After this patch, the rq_xtime field contains a timestamp that reflects the time just before the *first* call to ->sendmsg(). This is consequential under heavy workloads because large requests often take multiple ->sendmsg() calls to get all the bytes of a request queued. The TCP transport causes the request to sleep until the remote end of the socket has received enough bytes to clear space in the socket's local output buffer. This delay can be quite significant. The method introduced by this patch is a more accurate measure of RTT for stream transports, since the server can cause enough back pressure to delay (ie increase the latency of) requests from the client. Additionally, this patch corrects the behavior of the RDMA transport, which entirely neglected to initialize the rq_xtime field. RPC performance metrics for RDMA transports now display correct RPC request round trip times.

2008-07-09rpc: bring back cl_chattyOlga Kornievskaia
The cl_chatty flag alows us to control whether a given rpc client leaves "server X not responding, timed out" messages in the syslog. Such messages make sense for ordinary nfs clients (where an unresponsive server means applications on the mountpoint are probably hanging), but not for the callback client (which can fail more commonly, with the only result just of disabling some optimizations). Previously cl_chatty was removed, do to lack of users; reinstate it, and use it for the nfsd's callback client. Signed-off-by: J.

2008-07-09SUNRPC: Display some debugging information as text rather than numbersChuck Lever
In rpc_show_tasks(), display the program name, version number, procedure name and tk_action as human-readable variable-length text fields rather than columnar numbers. Doing the symbol lookup here helps in cases where we have actual debugging output from a kernel log, but don't have access to the kernel image or RPC module that generated the output. Sample output: -pid- flgs status -client- --rqstp- -timeout ---ops-- 5608 0001 -11 eeb42690 f6d93710 0 f8fa1764 nfsv3 WRITE a:call_transmit_status q:none 5609 0001 -11 eeb42690 f6d937e0 0 f8fa1764 nfsv3 WRITE a:call_status q:xprt_sending 5610 0001 -11 eeb42690 f6d93230 0 f8fa1764 nfsv3 WRITE a:call_status q:xprt_sending 5611 0001 -11 eeb42690 f6d93300 0 f8fa1764 nfsv3 WRITE a:call_status q:xprt_sending 5612 0001 -11 eeb42690 f6d93090 0 f8fa1764 nfsv3 WRITE a:call_status q:xprt_sending 5613 0001 -11 eeb42690 f6d933d0 0 f8fa1764 nfsv3 WRITE a:call_status q:xprt_sending 5614 0001 -11 eeb42690 f6d93cc0 0 f8fa1764 nfsv3 WRITE a:call_status q:xprt_sending 5615 0001 -11 eeb42690 f6d93a50 0 f8fa1764 nfsv3 WRITE a:call_status q:xprt_sending 5616 0001 -11 eeb42690 f6d93640 0 f8fa1764 nfsv3 WRITE a:call_status q:xprt_sending 5617 0001 -11 eeb42690 f6d93b20 0 f8fa1764 nfsv3 WRITE a:call_status q:xprt_sending 5618 0001 -11 eeb42690 f6d93160 0 f8fa1764 nfsv3 WRITE a:call_status q:xprt_sending Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

2008-07-09SUNRPC: Rename "call_" functions that are no longer FSM statesChuck Lever
The RPC client uses a finite state machine to move RPC tasks through each step of an RPC request. Each state is contained in a function in net/sunrpc/clnt.c, and named call_foo.

The special 'ENOMEM' case that was previously flagged as non-fatal is bogus: auth_gss always returns EAGAIN for non-fatal errors, and may in fact return ENOMEM in the special case where xdr_buf_read_netobj runs out of preallocated buffer space (invariably a _fatal_ error, since there is no provision for preallocating larger buffers).

2008-07-02svcrdma: Limit ORD based on client's advertised IRDTom Tucker
When adapters have differing IRD limits, the RDMA transport will fail to connect properly. The RDMA transport should use the client's advertised inbound read limit when computing its outbound read limit. For iWARP transports, there is currently no standard for exchanging IRD/ORD during connection establishment so the 'responder_resources' field in the connect event is the local device's limit. The RDMA transport can be configured to use a smaller ORD by writing the desired number to the /proc/sys/sunrpc/svc_rdma/max_outbound_read_requests file.
