From 7e2d130b1da457858791d8f8b00b17c821db039f Mon Sep 17 00:00:00 2001 From: Vlad Yasevich Date: Wed, 18 Jul 2007 02:52:33 -0700 Subject: [PATCH] Fix ipv6 link down handling. [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.
