Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 1126 Lines: 34 From: Vlad Yasevich [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.
