Week 1 (May 23 to May 29)

Day 1 (May 23)

Jumped into the code and had a look at the existing IPv6 implementation. I managed to figure out how to enable it again (with the right #defines in config.h) and was able to dump information about each IPv6 packet passing through the system. So far so good! The next steps will be getting IPv6 packets to the next layer up (ICMPv6, UDP and TCP) so I can start working on stateless autoconfiguration.

Zero-compression went in without a hitch, as per the project plan, but I'm going to have to come back to it. The code is fairly ugly…

I'm going to have to talk to Marty and Guo-Fu about the best way to integrate IPv6 for use in scripts and on the command line. I've been thinking (to myself) of having two new commands: “ipv6” to IPv6-enable an interface and set a link-local address, and “dhcpv6” to obtain an IPv6 address via DHCPv6. Not sure whether “dhcpv6” is a good name though as it'll break tab-completion for the “dhcp” command.

At this stage the work done so far is just in a patch file and a git commit.

All up, a good first day of GSoC 2011!
