Re: XFRM and IPv6 raw sockets and multicast

Hello.

In article [ref] (at Tue, 4 Dec 2007 16:27:50 +0100), "Hugo Santos" [off-list ref] says:

  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.

What do you mean by "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.

I think hdrincl is broken (and even, say, deprecated) on IPv6.

If we do really support it, if hdcincl is set, XFRM and other
all extension header processes should be skipped, but they are
not very clear at all so far.
