From ba5c35e0c7e30b095636cd58b0854fdbd3c32947 Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Wed, 18 Mar 2009 20:46:59 -0400 Subject: [PATCH] SUNRPC: Don't return EPROTONOSUPPORT in svc_register()'s helpers The RPC client returns -EPROTONOSUPPORT if there is a protocol version mismatch (ie the remote RPC server doesn't support the RPC protocol version sent by the client). Helpers for the svc_register() function return -EPROTONOSUPPORT if they don't recognize the passed-in IPPROTO_ value. These are two entirely different failure modes. Have the helpers return -ENOPROTOOPT instead of -EPROTONOSUPPORT. This will allow callers to determine more precisely what the underlying problem is, and decide to report or recover appropriately.
