- * This interface must manage two items concerning remote procedure calling:
- *
- * 1) An arbitrary number of transport connections upon which rpc requests
- * are received. The two most notable transports are TCP and UDP; they are
- * created and registered by routines in svc_tcp.c and svc_udp.c, respectively;
- * they in turn call xprt_register and xprt_unregister.
- *
- * 2) An arbitrary number of locally registered services. Services are
- * described by the following four data: program number, version number,
- * "service dispatch" function, a transport handle, and a boolean that
- * indicates whether or not the exported program should be registered with a
- * local binder service; if true the program's number and version and the
- * port number from the transport handle are registered with the binder.
- * These data are registered with the rpc svc system via svc_register.
- *
- * A service's dispatch function is called whenever an rpc request comes in
- * on a transport. The request's program and version numbers must match
- * those of the registered service. The dispatch function is passed two
- * parameters, struct svc_req * and SVCXPRT *, defined below.

- * When the service routine is called, it must first check to see if it

- * and return. If so, it should deserialize its arguments via
- * SVC_GETARGS (defined above). If the deserialization does not work,
- * svcerr_decode should be called followed by a return. Successful
- * decoding of the arguments should be followed the execution of the
- * procedure's code and a call to svc_sendreply.
- *
- * Also, if the service refuses to execute the procedure due to too-
- * weak authentication parameters, svcerr_weakauth should be called.
- * Note: do not confuse access-control failure with weak authentication!
- *
- * NB: In pure implementations of rpc, the caller always waits for a reply
- * msg. This message is sent when svc_sendreply is called.
- * Therefore pure service implementations should always call
- * svc_sendreply even if the function logically returns void; use
- * xdr.h - xdr_void for the xdr routine. HOWEVER, tcp based rpc allows
- * for the abuse of pure rpc via batched calling or pipelining. In the
- * case of a batched call, svc_sendreply should NOT be called since
- * this would send a return message, which is what batching tries to avoid.
- * It is the service/protocol writer's responsibility to know which calls are
- * batched and which are not. Warning: responding to batch calls may
- * deadlock the caller and server processes!
