From 9f9ef6d3c08319defc29e4cf6ef2868d15ed0cc3 Mon Sep 17 00:00:00 2001 From: Dax Kelson Date: Fri, 3 Feb 2012 23:40:25 -0700 Subject: [PATCH] iscsi: use IP_FREEBIND socket option Use IP_FREEBIND socket option so that iscsi portal configuration with explicit IP addresses can happen during boot, before network interfaces have been assigned IPs. This is especially important on systemd based Linux boxes where system boot happens asynchronously and non-trivial configuration must be done to get targetcli.service to start synchronously after the network is configured.
