All IP addresses that are present in a system are duplicated on struct sctp_sockaddr_entry. They are linked in the global list called sctp_local_addr_list. And this struct unions IPv4 and IPv6 addresses. So, there can be rare case, when a sockaddr_in.sin_addr coincides with the corresponding part of the sockaddr_in6 and the notifier for IPv4 will carry away an IPv6 entry. The fix is to check the family before comparing the addresses. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: Vlad Yasevich <vladislav.yasevich@hp.com> Signed-off-by: David S.
