Hello. I'm looking forward to participating in Google Summer of Code
2010. I plan to submit a proposal related to "Implement IPv6 support
for Haiku" project idea.
I am new to Haiku OS, but I have significant familiarity with IPv6 as
a programmer, as well as familiarity with Linux kernel networking code
and networking concepts in general. I feel enthusiastic about the
prospects of IPv6 protocol and think that it will soon become a really
necessary part of every desktop operating system.
At the moment I am studying the source code of Haiku OS and it's
network stack. Opinions regarding to what aspects of Haiku OS should
be learned first are welcome :)
What follows is a rough draft of the list of the points that are
required for IPv6 support (in my opinion). Please make your comments
about this list and the scope of its tasks.

Haiku IPv6 roadmap:
The points in different categories are sorted to roughly correspond to
the order of the implementation. This is not a ready proposal yet and
I do not claim that all these points will make it to my GSoC proposal.
* Addressing:
- basic IPv6 static addressing support
- neighbor discovery support (i.e. the equivalent of ARP for IPv6)
- DAD (duplicate address detection)
- dynamic link-local scoped addresses
- host side address autoconfiguration
* Routing
- connected route support
- default route support
- static route support
* API:
- AF_INET6 family support for sockets
This includes: [Vijayakumar]
adding sockaddr_in6 structure
writing support for IPv6 specific getsockopt and setsockopt calls
adding getnameinfo(), getaddrinfo(), inet_pton() and inet_ntop() functions
* Tools:
- ifconfig utility - allow to work with IPv6 addresses
- route utility - allow to work with IPv6 routes
- ping - for testing IPv6 connectivity and ICMPv6 support
- traceroute over IPv6 (UDP over IPv6 support required first)
- telnet over IPv6 (TCP over IPv6 support required first)
(later tasks:)
- FTP over IPv6 and wget over IPv6 (TCP required first)
* Protocols:
- limited ICMPv6 support, as much is needed to make address neighbor
discovery, DAD, autocofiguration, and ping to work.
Message types that need to be supported: [ICMPv6] [AutoConf] [NeighDisc]
- Echo Reply Message
- Echo Request Message
- Neighbor Solicitation Message (similar to ARP request for IPv4)
- Neighbor Advertisement Message (similar to ARP response for IPv4)
- Router Solicitation Message (Tx only)
- Router Advertisement Message (Rx only)
(not sure about whether there will be enough time for these:)
- TCP support over IPv6
- UDP support over IPv6
The main information about IPv6 is taken from [IPv6] and [Hagen].
The list does not contain points like "DHCPv6 client" or "tunnelling
support", that according to [von Gluck] can be supported without
implementing them in Haiku OS itself.
The lost also does not include support for RADVD (router side address
autoconfiguration). I don't think it's needed at all, at least for the
first releases of the OS, because Haiku OS is meant to be a host side
OS, not a router, right?
And it does not include support for multicast over IPv6 (MLD protocol)
or PPP over IPv6 support.
