From 37add3662de0339a75d3bed86a4235fc7efaf18d Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Fri, 19 Apr 2013 13:13:57 -0400 Subject: [PATCH] sm-notify: "-v hostname" doesn't work when IPV6_SUPPORT is enabled Marc Eshel reports that using the -v command line option on the sm-notify command stopped working after nfs-utils 1.2.2, when IPv6 support was added. If nfs-utils is built without IPv6 support, it still works. Marc specified a hostname with a single A record. smn_bind_address() must construct a bind address with the same family as the RPC socket's protocol family. Add an AI_V4MAPPED hint so an appropriate IPv6 bind address is constructed even if -v specifies an IPv4 presentation address, or a hostname with only IPv4 mappings. We still use an IPv4 bind address if IPv6 support is compiled out or the host does not support IPv6.
