As soon as we filled up the maximum number of -addresses of an interface, we stop installing more addresses and thus -also stop generating more temp addresses. - -Even if the attacker tries to generate a lot of temporary addresses -by announcing a prefix and removing it again (lifetime == 0) we won't -install more temp addresses, because the temporary addresses do count -to the maximum number of addresses, thus we would stop installing new -autoconfigured addresses when the limit is reached. - -This patch fixes CVE-2013-0343 (but other layer-2 attacks are still -possible). - -Thanks to Ding Tianhong to bring this topic up again. - -Cc: Ding Tianhong <dingtianhong@huawei.com> -Cc: George Kargiotakis <kargig@void.gr> -Cc: P J P <ppandit@redhat.com> -Cc: YOSHIFUJI Hideaki <yoshfuji@linux-ipv6.org> -Signed-off-by: Hannes Frederic Sowa <hannes@stressinduktion.org> -Acked-by: Ding Tianhong <dingtianhong@huawei.com> -Signed-off-by: David S.
