From bfeade087005278fc8cafe230b7658a4f40c5acb Mon Sep 17 00:00:00 2001 From: Daniel Lezcano Date: Thu, 10 Jan 2008 22:43:18 -0800 Subject: [NETNS][IPV6]: inet6_addr - check ipv6 address per namespace When a new address is added, we must check if the new address does not already exists. This patch makes this check to be aware of a network namespace, so the check will look if the address already exists for the specified network namespace. While the addresses are browsed, the addresses which do not belong to the namespace are discarded. Signed-off-by: Daniel Lezcano Signed-off-by: Benjamin Thery Signed-off-by: David S.
