From c3de1073e4ccbb0576024b54b0d4b16c17b7ff1d Mon Sep 17 00:00:00 2001 From: Lorenzo Colitti Date: Tue, 25 Oct 2011 11:35:57 +0800 Subject: net: Support nuking IPv6 sockets as well as IPv4. On Linux, when an interface goes down all its IPv6 addresses are deleted, so relying on knowing the previous IPv6 addresses on the interface is brittle. Instead, support nuking all sockets that are bound to IP addresses that are not configured and up on the system. This behaviour is triggered by specifying the unspecified address (:: or 0.0.0.0). If an IP address is specified, the behaviour is unchanged, except the ioctl now supports IPv6 as well as IPv4.
