From 58d29ececf8fc287d9b244c617edd174ded66b01 Mon Sep 17 00:00:00 2001 From: Jeff King Date: Mon, 14 Dec 2015 15:52:41 -0500 Subject: ident: fix undefined variable when NO_IPV6 is set Commit 00bce77 (ident.c: add support for IPv6, 2015-11-27) moved the "gethostbyname" call out of "add_domainname" and into the helper function "canonical_name". But when moving the code, it forgot that the "buf" variable is passed as "host" in the helper.
