From 4fbd3aa278903bfc74341aafaeef86ff98e82e09 Mon Sep 17 00:00:00 2001 From: Arjen de Korte Date: Mon, 5 Dec 2016 12:53:16 +0100 Subject: [PATCH] dnsmasq: Fix splitting hostid for DHCPv6 static leases Correct splitting the 32-bit 'hostid' value to two 16-bit hexadecimal values. Previously, the lower 16-bit value was truncated to an 8-bit value, which would result in hostid values 100 and 200 both to be set to [::0:0] instead of [::0:100] and [::0:200] respectively.
