From 063ed369c97f8de4cce23bf93bebd7ffacb542ff Mon Sep 17 00:00:00 2001 From: Vlad Yasevich Date: Sun, 15 Jul 2007 00:16:35 -0700 Subject: [PATCH] [IPV6]: Call inet6addr_chain notifiers on link down Currently if the link is brought down via ip link or ifconfig down, the inet6addr_chain notifiers are not called even though all the addresses are removed from the interface. This caused SCTP to add duplicate addresses to it's list. Signed-off-by: Vlad Yasevich Signed-off-by: David S.
