From 6cd7525a00f3b926e8bd2e402954ed3e09a8e924 Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Thu, 22 Sep 2005 21:24:59 -0400 Subject: SUNRPC: fix bug in patch "portmapper doesn't need a reserved port" The in-kernel portmapper does in fact need a reserved port when registering new services, but not when performing bind queries. Ensure that we distinguish between the two cases.
