OpenWrt Summit schedule is shaping up to be perfect for all levels of experience in the community. 15 sessions, including lightning talks, feature speakers from all parts of the OpenWrt community. The following sessions have been accepted:

Introduction to OpenWrt
Steven Barth

An overview over the OpenWrt project, the people involved and its infrastructure.

This talk describes the different groups of contributors, the package maintenance process, our release model and a number of community and commerical users and usecases.

Introducing the OpenWrt network subsystem
Steven Barth

Introducing the most distinctive part of the OpenWrt firmware: the network configuration and management layer. This talk describes basic OpenWrt components like the network interface daemon (netifd), the firewall and interactions with the kernel and other daemons (e.g. client configuration). It explains how devices like wifi, ethernet or tunnels are configured and how network protocols like DHCP(v6) operate on top of them. The talk shows and explains simple and complex interactions based on real-world examples.

Adding new SoC to OpenWrt
Hauke Mehrtens

In this session I want to present the preferred ways on how to integrate support for a new SoC into OpenWrt. This will cover how to handle patches, drivers not in the mainline Linux kernel and kernel configuration. In addition it is shown how to generate images which can be flashed onto a board and how to handle different generations of a SoC and different boards using the same SoC.

Project Turris - open router with OpenWrt
Bedrich Kosata

Project Turris ( is a security related research project which uses a powerful custom router running OpenWrt to analyze malicious network traffic. In this short presentation we will briefly introduce the project and how it uses OpenWrt. We will touch on topics such as forking of OpenWrt and working with upstream sources. We will also show a few extra features we have added to our fork, such as automatic updates, local network bandwidth usage statistics, etc. Last but not least, we will introduce our new hardware built directly for OpenWrt running on Marvell Armada 385 (

Do you really need to fork OpenWRT?
Federico Capoano

OpenWISP Firmware is an OpenWRT derived firmware designed to work in municipal wifi settings, since the project started in 2007 the OpenWISP developers refactored it several times using different strategies, learning some important lessons that they would like to share with the OpenWRT community.

During this session you will hear about the benefits of packaging, the disadvantages of not following best practices in forking OpenWRT and a few experimental ideas about automated compilation testing on and hardware testing.

Supporting services across multiple WAN interfaces
Hans Dedecker

Most OpenWrt users need just one single WAN interface. As Technicolor, we are confronted with telcos requiring multiple services on the WAN. For example, they might want to separate data, video, voice and management traffic in multiple VLANs.

OpenWrt does not provide an out of the box solution for this use case today. In this presentation, we will describe the use cases in more detail and present our solution which includes extensions to the UCI data model, new OpenWrt packages and scripts and a specific configuration.

Panel discussion: many companies leverage OpenWrt -- a peek from the inside
Kathy Giori

Without open source software collaboration, much time and effort is wasted by companies or individuals re-inventing the wheel. Companies who need to maintain a small-footprint embedded Linux stack therefore benefit from leveraging OpenWrt. But what challenges arise when corporate interests clash with community ideals? In this panel discussion we invite a few engineers from industry to describe how they manage their forked distributions of OpenWrt, and what they think can be done to improve industry collaboration with the community such that they help improve the community project from which they pull.


  • Imre Kaloz -- representing Belkin/Linksys
  • Matthew McClintock -- Qualcomm Atheros
  • Mimmo La Fauci -- Linino (and Arduino)
  • Roman Yeryomin -- Ubiquiti Networks
  • Delbar Jos -- Technicolor

OpenWrt and Linux Containers
Luka Perkov

Today in almost every home we have a router and gateway which connects the home network to the Internet. This essential networking device often lacks proper security measures and in the recent years has been a target of malicious attacks. As more and more users and companies turn to OpenWrt project the security aspect of OpenWrt becomes even more important. This talk will give more insight into OpenWrt and Linux Containers integration and show how to run the custom made Linux Containers in OpenWrt.

Security and Hardening
Steven Barth

Introducing new and ongoing security improvements to bleeding edge OpenWrt. This talk describes the new default toolchain featuring musl libc, enabled hardening including ASLR, SSP as well as OpenWrt's novel jailing (jailfs and seccomp) and package signing features (based on Curve25519).

Securing the Internet of (broken) Things
Cesare Garlati

As connected devices become increasingly pervasive, so are the risks associated with the exploitation of their vulnerabilities. From cars to airliners, from self-aiming rifles to drug delivery pumps, the threat represented by these devices has the potential to become a matter of life and death for millions. In this session Cesare Garlati, Co-Chair of the Mobile Group at the Cloud Security Alliance and Chief Security Strategist at prpl Foundation, will present a technical analysis of some of the most recent incidents, identify common attack patterns and propose a framework to harden the security of these systems.

Extending the UCI Data Model
Jos Delbar

The use cases that Technicolor is addressing with Homeware have required us to extend and/or adapt OpenWrt's data model in several domains, including but not limited to:

  • physical layer: VDSL, PON, LTE, DOCSIS
  • advanced switch configuration
  • quality of service
  • wireless

In this presentation, we would like to explain several use cases, motivate the changes and propose improvements that could make sense to the broader OpenWrt community. Also, in more general terms, we would like to test the waters for potential collaboration and standardization efforts around UCI.

Lightning talks[edit]

One hour of the day is set up for five minute lightning talks. With only five minutes (including setup), speakers have to quickly highlight a topic. If you'd like to perform a lightning talk, please add it to the list below.
