Re: [libvirt] [PATCH] util: don't log failure when older iptables lacks -w

Commit dc33e6e4 caused older platforms like Fedora 20 to emit scary log messages at startup: 2014-11-19 23:12:58.800+0000: 28906: error : virCommandWait:2532 : internal error: Child process (/usr/sbin/iptables -w -L -n) unexpected exit status 2: iptables v1.4.19.1: unknown option "-w" Try `iptables -h' or 'iptables --help' for more information. Since we are probing and expect to handle the case where -w is not supported, we should not let virCommand log it as an error. * src/util/virfirewall.c (virFirewallCheckUpdateLock): Handle non-zero status ourselves.
