Date: Tue, 4 Dec 2007 16:27:50 +0100 From: "Hugo Santos" <hugosantos@...il.com> To: netdev@...r.kernel.org Subject: XFRM and IPv6 raw sockets and multicast Hi, I've ran into an issue which i'm not sure that is known. I'm able to provide a patch if people feel this is something that should be fixed. Anyway, the source address of packets is not taken into account when matching for xfrm policies when socket(AF_INET6, SOCK_RAW, IPPROTO_RAW) sockets are used. This doesn't allow for (S,G) policies to be deployed for IPv6 for local output packets as is required for some multicast communications (read: SSM). The behavior is the same as in UDP, but ipv6_pinfo->saddr is not usually set for these kind of sockets. I would say that if fl6_src is any, it should be copied from the ipv6 header. Another question is why does raw.c require a msg_name? If inet->hdrincl was set, it could use the ipv6 header destination address in the absense of msg_name. Any comments? :-) Thanks, Hugo -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
