From bbe83862a5e1baf15f7c923352d4afdf59bc70e2 Mon Sep 17 00:00:00 2001 From: Jan Engelhardt Date: Sat, 24 Oct 2009 00:45:33 +0200 Subject: iptables/extensions: make bundled options work again When using a bundled option like "-ptcp", 'argv[optind-1]' would logically point to "-ptcp", but this is obviously not right. 'optarg' is needed instead, which if properly offset to "tcp". Not all places change optind-based access to optarg; where look-ahead is needed, such as for tcp's --tcp-flags option for example, optind is ok.
