From eb867579311a9c1e998d6911af056772c400122a Mon Sep 17 00:00:00 2001 From: "Denis V. Lunev" Date: Thu, 3 Apr 2008 13:31:53 -0700 Subject: [PATCH] [IPV6]: inet6_dev on loopback should be kept until namespace stop. In the other case it will be destroyed when last address will be removed from lo inside a namespace. This will break IPv6 in several places. The most obvious one is ip6_dst_ifdown.
