From 99bc9c4e45e7e783cf0b0a25cc03a103c038f254 Mon Sep 17 00:00:00 2001 From: Daniel Lezcano Date: Thu, 10 Jan 2008 02:54:53 -0800 Subject: [NETNS][IPV6]: Make bindv6only sysctl per namespace. This patch moves the bindv6only sysctl to the network namespace structure. Until the ipv6 protocol is not per namespace, the sysctl variable is always from the initial network namespace.
