This one was taken off the the system actually running the patch so I know this one is correct. I just retested, turning on temporary addresses as well, and the notification happen correctly. I was expecting an ACK from Yoshifuji-san before you applied it so feel free to wait for it. -vlad -- 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.
