Date: Tue, 6 May 2008 16:38:04 +0300 From: "David Shwatrz" <dshwatrz@...il.com> To: netdev@...r.kernel.org, "YOSHIFUJI Hideaki / 吉藤英明" <yoshfuji@...ux-ipv6.org> Subject: A question about setting the net device for multicast forwarding in IPv4 and in IPv6 Hi, I had noticed that in IPV4 we set the net device for multicast forwarding in case it is not already configured so, when the user space app calls setsockopt() with MRT_INIT; this is done by calling IPV4_DEVCONF_ALL(sock_net(sk), MC_FORWARDING)++; in ip_mroute_setsockopt(); (net/ipv4/ipmr.c). On the other hand, the parallel method in IPv6 does **not** performs such action, as can be seen from ip6_mroute_setsockopt() in net/ipv6/ip6mr.c. My question is : is there any special for it to be so? (In case it should be also in IPv6, I will happy to send such a patch).
