--3V7upXqbjpZ4EhLz Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable Hi all, The goal of this project is to create a Netgraph node that acts as a link between a socket (TCP, UDP, SCTP, ...) connection to an AYIYA server (for a start, the SixXS POPs) and a local network interface (for a start, one that can route IPv6 traffic). Wiki: https://wiki.freebsd.org/SummerOfCode2015/AYIYASixXSNetgraphNode Subversion: https://svnweb.freebsd.org/socsvn/soc2015/roam/ Testing: https://svnweb.freebsd.org/socsvn/soc2015/roam/README.txt?view=3Dco This is the final report for this project; the ng_ayiya node is ready for testing and, IMHO, for use with the SixXS AICCU tool. There is still quite some room for improvement, e.g. some fixes to the configuration and the shutdown of the AICCU tool, but the Netgraph AYIYA implementation is fully usable at least in the following scenarios: - run aiccu as a TIC+AYIYA client against the actual SixXS servers to operate a "real-world" SixXS IPv6-over-IPv4 AYIYA tunnel - run aiccu as a TIC+AYIYA client against a local TIC server from my Net-SixXS Perl distribution and a local AYIYA server from the ng_ayiya package (the GSoC product) - configure two ng_ayiya nodes, either by hand or using a helper script from the ng_ayiya package, as two sides of a local AYIYA tunnel The last couple of weeks of the GSoC work were mainly focused on the first two scenarios: using and testing the SixXS AICCU tool's operation against the real SixXS servers and against a newly-written ayiya_listen utility that waits for incoming UDP packets on port 5072 that have not been claimed by any established tunnel, figures out which of the configured tunnels the packet is for, sets up the Netgraph nodes for the tunnel's operation, and starts up an ayiya_resp instance for this tunnel to handle the initial packet and any more packets that have arrived before the Netgraph nodes have been configured. Again, there is some room for improvement there, especially with restarting the remote side of a tunnel, but this listener, along with the additional functionality of the ayiya_resp tool (read a packet from the listener and pass it on to the ng_ayiya node for processing) and the ng_ayiya node itself (inject a packet as if it had arrived over the wire), should be usable now. Due to quite some time mismanagement on my part, my mentor and I did not get to the step of performance testing aiccu+ng_ayiya vs. aiccu+tun during the GSoC timeframe as we had planned, but the functionality to do the testing should be in place now.
