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
