Message-ID: <4AF85401.3020906@gmail.com> Date: Mon, 09 Nov 2009 18:40:17 +0100 From: Eric Dumazet <eric.dumazet@...il.com> To: "David S. Miller" <davem@...emloft.net> CC: Linux Netdev List <netdev@...r.kernel.org> Subject: [PATCH] ipv6: Allow inet6_dump_addr() to handle more than 64 addresses Apparently, inet6_dump_addr() is not able to handle more than 64 ipv6 addresses per device. We must break from inner loops in case skb is full, or else cursor is put at the end of list.
