This year, the Google Summer of Code and FreiFunk have given to Guifi.net and QMP communities the opportunity to develope a project in this event. This project is: BGP/Bird integration with OpenWRT and QMP.
A brief description of the project
Most of the community networks run dynamic routing protocols (OLSR, BMX6, BATMAN-ADV, etc.) with non-dynamic ones (BGP, OSPF, etc.). Guifi.net (BGP) and QMP (BMX6) are a scenario where this collision of metrics and routes happens.
Furthermore, these communities are using Quagga for the BGP routing, which is a complex and oversized tool for the type of nodes that will work with it. For these kind of nodes, Bird is a really lightweight BGP daemon that is still not well supported to be used easily by the community (it does not have an easy and graphical configuration system yet).
This project will contribute with:
1st Block: Adapting Bird to fit into QMP firmware. (1 month)
2n Block: Automate the translations of routes and metrics between a non-dynamic routing protocol and a dynamic one. (~2 months)
3rd Block: Project basic feedback and documentation (1 week)

The project tutors are Roger Baig (fundació Guifi.net) and Axel Neumann (Freifunk and BMX6 support) and the special collaboration of Pau Escrich (fundació Guifi.net and QMP project).
The summer of code project of Steven Barth aka Cyrus is about planning and implementing an IPv6 and TLS capable superserver in Lua as well as an HTTP/1.1-Server working on top of it using the LuCI HTTP-Stack. This application will serve LuCI - the Freifunk Firmware web user interface - and replace the currently used slower CGI-solution without IPv6 and encryption support. Additionally an RPC-Server will be built to allow remote administration of one or more OpenWrt devices in a standardized way using JSON-RPC over TCP.
The results of the summer work of Cyrus is pretty overwhelming. There is for example nixio, the new POSIX Lua library which will help us getting rid of the Lua 3rd party library mess. And based on that there is also LuCId - which was described in the GSoC project. It brings us a new efficient HTTP-server. Some people may have discovered that Cyrus already checked in things into trunk ocassionally. Also SSL support is working. Another nice new feature is native support for creating wizards which will be used in the near future. The results of LuCId are already being tested in productive environments. They are performing well. Kernel mode IO and TLS encryption function well. Special thanks for the achievements also go to John Crispin aka BLogic who is the mentor of Steve during the summer.
The OpenWrt team (Cph) has announced a new version of its Linux distribution for embedded wireless devices named "OpenWrt Kamikaze 808 Release". I talked to Felix Fietkau already at the WCW. Unfortunately we did not have the time to do an interview at the end. But Cyrus from freifunk Halle gave a short showcase of his interface (in German). The OpenWrt team was also impressed by it and they now announce the enclosure of the Luci interface officially. Congratulations Cyrus!
It has been quite a while since OpenWrt had a new Kamikaze release. The developer team has decided that it is time to get things straight and focus on a new release. This release have the official name: OpenWrt Kamikaze 808 Release.
The schedule will look like this:
*Last day in July - final release candidate: 808 RC-1 808 RC-1 will be a feature freeze, and all changes after this point will be bug fixes.
*Last day in August - final release: OpenWrt Kamikaze 808 Release.
OpenWrt Kamikaze 808 Release will focus on bringing the following:
- Firewall rewrite
- Broadcom 47xx running reliably with the new Kernel, not including wifi
- IMQ and Traffic shaping tested with newer kernels, especially 2.6.25
- Sysupgrade for more platforms (x86 is tested again)
- The new web interface (LuCI, Lua Configuration Interface)
- Attention towards the integration of security updates
- Package maintaining and updates between releases
- Testing, testing and lots of testing...
The 808 Release will also include support for several new platforms/targets. (http://forum.openwrt.org/viewtopic.php?pid=69873 )
Steven Cyrus Barth im Gespräch mit Bastian Bittorf über das Freifunk-Luci-Interface für OpenWRT.
Some more info in English: FFLuCI is a Lua MVC-Framework for Freifunk with templating support. There are working configuration pages for many system, network, services and wifi settings. Please visit http://luci.freifunk-halle.net for an overview of functions, screenshots, tutorials, SVN URL and snapshot images for Atheros and Broadcom.
Steven Cyrus started to develop Luci because he was not satisfied projects like XWRT implemented things. He had a look at the X-WRT Lua files in their repository first, but what was missing was a clear abstraction layer and templating support so I decided to build everything from scratch. According to Cyrus - X-WRT has a very nice UI written in shell code but there are only limited capabilities of this scripting language and so "it is time
to bring this thing to the next level using OOP and such nifty stuff."
Luci already has a number of working configuration pages. There are more - or in a few cases less - working configuration pages in (for now) German titles and descriptions for the:
Also there are a few public status pages for basic system information, WLAN-Scan, Contact data and OLSR a bit like those in the Freifunk Firmware. Have a look at the screenshots here: http://firmware.freifunk-halle
Configuration Bind Interface (CBI):
You just describe the data model of the UCI file and Luci does the rest for you: It will create the HTML-form, parse and validate the user input and write the configuration data to UCI. So no need to redo all these things on every configuration page again and again. It also supports basic field dependencies, dynamic validation functions, section creation, deletion and more. See an example here: http://wiki.freifunk-halle.net
To avoid remote exploits (like those in older versions of the Freifunk Firmware) FFLuCI will set the UID/GID of pages running in the main public non-protected section to nobody/nogroup. There are many things left to do like porting over dhcpsplash, accounting, statistics and more to Kamikaze. Contributors are welcome.
