Subject: A question about setting the net device for multicast forwarding in IPv4 and in IPv6
Date: Tue, 6 May 2008 16:38:04 +0300 [thread overview]
Message-ID: <31436f4a0805060638o2f97e3d7v8355fb678454da47@mail.gmail.com> (raw)
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).
Best Regards,
DS
