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

SUNRPC: Simplify rpcb_register() API

2008-09-29T22:13:37+00:00

Bruce suggested there's no need to expose the difference between an error sending the PMAP_SET request and an error reply from the portmapper to rpcb_register's callers. The user space equivalent of rpcb_register() is pmap_set(3), which returns a bool_t : either the PMAP set worked, or it didn't. Simple. So let's remove the "*okay" argument from rpcb_register() and rpcb_v4_register(), and simply return an error if any part of the call didn't work. Signed-off-by: Chuck Lever Signed-off-by: J.

SUNRPC: Support registering IPv6 interfaces with local rpcbind daemon

2008-07-15T22:08:55+00:00

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. Signed-off-by: Chuck Lever Signed-off-by: J.

rpc: bring back cl_chatty

2008-07-09T16:09:10+00:00

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. Bruce Fields Signed-off-by: Trond Myklebust

SUNRPC: Use appropriate argument types in rpcb client

2008-01-30T07:06:09+00:00

Clean up: Follow recommendations of Chapter 5 of Documentation/CodingStyle and use "u32" instead of "__u32" for types in definitions that are not shared with user space. Signed-off-by: Chuck Lever Signed-off-by: Trond Myklebust

SUNRPC: fewer conditionals in the format_ip_address routines

2008-01-30T07:06:04+00:00

Clean up: have the set up routines explicitly pass the strings to be used for the transport name and NETID. This removes a number of conditionals and dependencies on rpc_xprt.prot, which is overloaded. Tighten up type checking on the address_strings array while we're at it.

SUNRPC: Add support for per-client timeout values

2008-01-30T07:05:59+00:00

In order to be able to support setting the timeo and retrans parameters on a per-mountpoint basis, we move the rpc_timeout structure into the rpc_clnt. Signed-off-by: Trond Myklebust
