From 1c8d287e58a3199213b5533136a7a04c8eb231bb Mon Sep 17 00:00:00 2001 From: Kenneth Soerensen Date: Fri, 20 Dec 2013 15:53:01 +0100 Subject: inet: Fix threaded res_init In a multi-threaded application where res_init() was called either directly or implicitly, getaddrinfo() and others failed to add the DNS search domain to hostnames. This problem made it not possible to look up a hostname without its domain appended. The problem is caused by res_sync_func() overwriting the configuration read by __open_nameservers() immediately after it is read. The suggested solutin is to disable res_sync_func() while reading name server configuration in res_init().
