Our GSoC 2017 projects

In 2017 we got 15 slots for our projects. That’s great, we’ve never got so many slots for GSoC before. Our students are from 8 countries. They do their work for 6 sub organizations.

Until the end of May the Community Bonding Period takes place, so students can introduce their projects to the community. They also prepare together with their mentors the folling coding period.

This post will give a short overview on the selected projects. In the next weeks some detailed blog posts will follow describing all the projects.

GSoC project overview

Title Org Student Abstract
RetroShare Improvements retroshare ange The aim of this proposal is to improve RetroShare incrementally during the summer in the following work lines:
– Semi-automatic RetroShare friendship suggestion based on phone contacts
– Semi-automatize JSON API code and documentation generation
– Multiple simultaneous heterogeneous network connection for each peer
– Improve RetroShare Android usability and performances
– Seamless key exchange via Quiet Modem
– Chat and messages multiple device synchronization
– Directories multiple device synchronization
Implementing Pop-Routing in OSPF ninux Gabriele Gemmi Prince is a network daemon that continuosly monitors the network topology and sets the timers for OLSRv2, it is developed in C and we are currently deploying it in the Ninux community network in Florence. This year
we want to implement Pop-Routing for another link-state routing protocol: OSPF. OSPF is the state-of-the-art interior routing protocol for wired networks and it is used also in some wireless community networks. This
project consists in realizing a plug-in of the OSPF open source routing daemon (Quagga or Bird) that will:
– Expose the network topology to Prince using NetJson
– Receive and re-set the network parameters from Prince
Improving nodewatcher data representation capability wlan slovenija rasovica Currently nodewatcher has very limited overview of used IP space without more precise division of existing and used subnets. This could be improved using compact and colorful matrix with IP ranges and links to nodes. I would display data about used ips similar to the [IP Census 2014](http://census2012.sourceforge.net/images/hilbert_icmp_map_lowquality.jpg), better tables and other data representation that would help explain the network structure, it would help in explaining the network and its statistics even to an uninformed observer. I would also update the look and functionality of other graphs and tables representing statistical data from nodewatcher
Extending LoxiGen and ONOS to enable SDN control of wireless switches via OpenFlow lede Arne Kappen LoxiGen is a tool by the Floodlight project to generate OpenFlow libraries for several programming languages including Java and C. The goal of this project is to extend LoxiGen to include messages for controlling wireless switches using OpenFlow.
It will include the necessary extensions to LoxiGen as well as a proof-of-concept implementation of the control channel. This encompasses an application for the ONOS SDN controller and an agent for the LEDE router operating system.SDN-enabled wireless switches offer comfortable centralized management of larger deployments and may provide the basis for more complex use-cases in the future such as network slicing and seamless mobility.
OpenWRT/LEDE Configuration Management lede Johannes Wegener Improve the proof-of-conecpt version of a OpenWRT/LEDE configuration software.
Web interface for Retroshare, a secure communication software retroshare Stefan Cokovski I am applying to work on the web interface for RetroShare, secure communication software. RetroShare already has a web interface with limited functionality and questionable look, compared to the main Qt GUI which RetroShare uses. My goal will be to improve the already present functionalities, introduce new functionalities to the web interface and design a new look for the web interface.
Implement NetJSON output in ubus (OpenWRT/LEDE) lede Arunkumar Ravichandran To bring in support for NETJSON object in the LEDE/OpenWRT Linux distributions. The support for NETJSON is brought in at the interconnect system- ubus. To add support for a new ubus API which allows retrieving these two NetJSON object types: DeviceConfiguration and DeviceMonitoring.
DeviceConfiguration NetJSON object is filled in using the plugins available in System Configuration Abstraction Layer(SCAL).
DeviceMonitoring NetJSON is retrieved by reusing the code parts and adding hooks in the nodewatcher-agent.
LibreMesh Attended Sysupgrade libremesh paul0 Performing updates on routers is quite different from full Linux distribution. It’s not sustainable to do release upgrade via a packet manager. Instead it’s usually required to re-flash the system image. Depending on the installed packages an image rebuild may be to complex for regular users. A more convenient way is needed.

This project will implement an “image as a service” server side which provides custom build images depending on installed packages. A notification in the web interface will notify about the new release. After image creation a one-click installation is offered within the web interface.

The server side implementation will use established tools like LEDE’s ImageBuilder to provide an generic approach for image creating. In this way the entire OpenWrt/LEDE community including several community-mesh firmware projects will benefit from that new update routine.

Spectrum Analyzer libremesh Nicolas Andres Pace I believe that Community Networks’ Operating Systems could use the Spectrum Analysis a lot to make better decisions on how they use the electromagnetic field wisely and efficiently.

As of now, no Free OS has been using Spectrum Analysis, so they can’t know whether the radios are being used efficiently or not.

This module would allow all routers that use Atheros radios (the main radio manufaturer around) to see how is the spectrum and take better decisions on which channels they use.

* Create an OpenWRT/LEDE package to get Spectrum info from the radio.
* Create a LuCI interface to visualize the Spectrum information retrieved.

HMAC signing of Nodewatcher data & IPv6 support for Tunneldigger wlan slovenija red_moo Currently all monitoring reports by WLAN nodes are unsigned and can be spoofed by anyone. This represents a security problem and a possible solution is to add HMAC-based signing to encrypt node monitoring reports to prevent spoofing.
Nodewatcher’s monitoring system will also be improved so it will generate an event and a warning in case of a signature verification failure.The aim of the second part of this GSoC project is to design and implement IPv6 support for Tunneldigger so that it works in IPv6-only and IPv4/IPV6 mixed environment where both server and client have IPv6 connectivity in some form.
Add MPTCP support in LEDE/OpenWRT trunk lede SPYFF Create an MPTCP supported OpenWRT/LEDE trunk and ensure its operation in a multipath Wi-Fi aggregation environment. The trunk should contain the tooling for establish a SOCKS proxy for operating systems without MPTCP support.
geolocator (Software defined GPS) FF Nordwest Jan-Tarek Butt A dynamical and flexible geolocator which should provide a software defined GPS device and receives its position over WIFI hardware with various services like openwifi.su, MLS and etc.
netjsongraph.js: visualization of netjson data ninux GeekPlux NetJSON is a great work attracted some interest from around the world, but there are a lot of defects. And I’m a front-end developer and now focus on Data Visualization, so I want to contribute to NetJSON. In my proposal, I come up with my idea and list some tasks and schedules.
lime-webui: port to LuCI2 libremesh Marcos Gutierrez Make an inventory of all LuCI components that LibreMesh uses and that will not be compatible with LuCI2. Analyze which dependencies must be replaced or rewritten and generate the views according to the new framework selected.
Powquty Live-Log lede Stefan Venz PowQuty provides statistics from measurements taken by a USB oscilloscope. The statistics provide information about the power distribution network, but don’t highlight the most important information. Power networks need to comply with EN50160, if this norm is violated, damage to connected devices is possible.
To avoid damage, powqutyd will log violations and notify users on occurrence.
