| * | | | | | | | | | | | | SUNRPC: use sockaddr + size when creating remote transport endpointsChuck Lever2006-09-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Prepare for more generic transport endpoint handling needed by transports that might use different forms of addressing, such as IPv6. Introduce a single function call to replace the two-call xprt_create_proto/rpc_create_client API. Define a new rpc_create_args structure that allows callers to pass in remote endpoint addresses of varying length. Test-plan: Compile kernel with CONFIG_NFS enabled.

| * | | | | | | | | | | | | SUNRPC: Use "sockaddr_storage" for storing RPC client's remote peer addressChuck Lever2006-09-22

Now that no RPC client consumers treat the addr field in rpc_xprt structs as an opaque, and access it only via the API calls, we can safely widen the field in the rpc_xprt struct to accomodate larger addresses.

A set of per-xprt bitops is used to serialize tasks during RPC binding, just like it now works for making RPC transport connections.
