Hi,
I think that you were still using IP_HDRINCL socket option for IPv6. In
IPv6, IP_HDRINCL should be replaced by IPV6_HDRINCL for a raw socket. You
may refer to this article for more information:
IPPROTO_IPV6 Socket Options
http://msdn2.microsoft.com/en-us/library/ms738574(VS.85).aspx
socket Function
http://msdn2.microsoft.com/en-us/library/ms740506(VS.85).aspx

Hope this helps. If you have any other questions or concerns, please feel
free to let me know.

Hi,

Our OS is XP Embedded with SP2.

We have tried IPV6_HDRINCL but with no luck. Its documentation says "header
will be supplied on all outgoing data" which indicates that it does NOT
affect inbound packets.

Any other ideas on how to get inbound IPv6 headers?

Thanks,

/ Hannes.

Hi Hannes,
I am afraid that you could not get IPv6 header for inbound packets since it
is a by design limitation for IPv6 packet. From the second article (socket
Function) provided in my last response, you can find the following
description:
---------------------------------------------------------
IPv6 and IPv4 operate differently when receiving a socket with a type of
SOCK_RAW. The IPv4 receive packet includes the packet payload, the next
upper-level header (for example, the IP header for a TCP or UDP packet),
and the IPv4 packet header. The IPv6 receive packet includes the packet
payload and the next upper-level header. The IPv6 receive packet never
includes the IPv6 packet header.
----------------------------------------------------------

Could you please let me know why you would like to get IPv6 header for
inbound packets?

Hi,

We need the IPv6 header for a couple of reasons:
1. To read the DiffServ/ToS/TrafficClass from inbound packets (our
application uses that for internal prioritization)
2. To read TTL of inbound ICMP packets; our application also uses the
TTL/HopLimit to implement an ICMP "ping"-like functionality

Thanks,

/ Hannes.

Hi Hannes,
Thanks for your response.
I will try to consult the Dev team to see if they have some good
suggestions on your specific requirements. Could you please just leave me
(changliw_at_microsoft_dot_com) an email response so that I can timely
update you?

However I appreciate your understanding that since this is a by design
limitations at TCP/IP protocol, probably you may have to reconsider your
requirements or even eliminate these two requirements for IPv6 environment.

Just clarify that we are still in consulting on this issue and have not got
a solution right now ( may not have a real solution since it is not
supported by design). I will try to follow up the dev team on this and will
post back as soon as possible. Appreciate your patience!

Was there ever any resolution to this? I see that the microsoft documentation on MSDN still states that the IPV6 header is never received,even on a socket with the
header included option set. Curios if any one has a work around.

Thanks,
Kyle

Hi,

From our raw IPv6 socket, we're not getting the IPv6 header, only the
following IP payload is given to us.

We had no issues getting the IPv4 header from raw IPv4 sockets.
Has this functionality changed for IPv6, or are we missing a socket option?

Thanks,

/ Hannes.
