The Linux kernel already has cryptographic support for signature verification on data. This is used to digitally sign kernel modules at build time, and verify integrity and provenance at load time. Likewise the 802.11 subsystem on the Linux kernel had historically in parallel prior to Linux's own kernel signing facility implemented and integrated support to verify file integrity and provenance for use on the Linux regulatory database. The 802.11 subsystem's components that provide this facility are CRDA and wireless-regdb. CRDA and wireless-regdb technically are split up as two separate trees for development, wireless-regdb helps provide the 802.11 regulatory database while CRDA exists as a udev helper to feed to the Linux kernel a regulatory domain when needed. By using a regulatory database in userspace the Linux kernel is able to get updates for regulatory rules without requiring a rebuild. Linux distributions need the digitally signed regulatory.bin file from wireless-regdb tree and the CRDA binary from the CRDA tree. Linux distributions often combine both into one package, some distributions separate the two. The regulatory database is digitally signed by the wireless-regdb maintainer, and distributions that have have compiled in support for digital signature support on CRDA verify the integrity of the file before feeding a regulatory domain to the Linux kernel. Since the kernel module signing facility was merged upstream on Linux we could replace both CRDA and wireless-regdb distribution mechanism by adding cryptographic file signature verification support on Linux on the firmware_class module which provides the APIs to load firmware, and having the regulatory.bin file merged and updated through the linux-firmware tree.

I think AppArmor is a great tool to add an additional layer of security without much effort. While it is normally easy to create a profile for a simple server program it is much more complex in case of desktop applications.

Package open source tools used for radio controled models. Some of them needs patching, since they rely on pre-build binary blobs of open source tools. Also many of them bring the same libraries again.

Create a openSUSE 13.2 Live CD.

Write an Android app for children between 5 and 7 years. The app contains a story that the child can read and interact with.

We will have a series of short lightning talks to present what we have accomplished at Hack Week 12. In Nürnberg this will happen on Friday 17th Apr at 12:30 as part of the lunch session in the all-hands area. Lunch is served at 12:00, so you have a bit of time to settle in and satisfy your immediate needs before we go into presentation mode.

A new web UI for saltstack, possibly the future of systems management.

OBS source services can currenlty run on the developer workstation and some of them also on the OBS server side.

In previous Hackweeks, we've gone to warp speed in our virtualization CI testing through:

Create packages for SLES 12 s390x in obs.

Scaleway is a newly opened Cloud based in France (for now) offering ARM based servers. Those are BareMetal SSD cloud servers. They offer a range of operating systems to pick from (Debian, Ubuntu, ArchLinux...) as well as 'application images' (Docker, ownCloud...) but no openSUSE image yet.

Or at least, test as many of them as possible.

As a part of this hackweek, I'd like to take a look at Clojure and use it to solve as many problems as possible from the project euler.

Discourse is a really great opensource forum, written in Ruby on Rails and Ember.js.

Needing to learn git, I thought it would be a good time to clean up the code and create a git project for it.

Record two songs by the end of the week.

The docker way of updating containers is to build a new image with the updated binaries and files, which creates a security concern.

kGraft allows to patch kernel at runtime. It implements a consistency model that allows to modify semantic of functions. e.g. fix lock order. For this, we need to find a safe place when a process/thread might start using the new code.

I am a beginner: I have read 1½ books on Haskell. I want to practice.

Ionic + AngularJS + Node.js (http://ionicframework.com/)

For development purpose, it is very useful to have an infrastructure that can spot regressions based on commit base. Currently, our existing infrastructure runs mainly SPEC benchmark and is cumbersome from perspective of any further development. I would like to build a replacement that will combine buildbot framework with a custom web project (based on Django framework). The web project will be used both for submitting reports coming from a buildbot slave and for UI which will serve plots and data.

Squeezeboxserver

Elasto is a cloud storage client project that has been developed across a number of SUSE Hack Weeks.
It currently supports Amazon S3 and Microsoft Azure REST storage protocols, and includes a POSIX like file API.

open-sTeam is a platform for cooperative work and cooperative learning developed at the university of paderborn in germany. the platform is being used at http://societyserver.org/ and is being developed further.

The user space interface of evdev is pretty generic. All hardware abstraction is done in the kernel driver, device properties are mapped to a set of generic properties. The properties can be queried thru a generic interface only very few parameters are set from user space. In user space the evdev API is used by Xorg's evdev driver and libinput.

Apache Maven is a build tool used by many Java projects, which is incompatible with OBS in that it tries to download binary dependencies from the Internet. Several people have in the past years tried to somehow bootstrap Maven and failed.

I'd like to learn how to use Robot Framework for doing Acceptance Tests of a cli application: Machinery.

PXE boot is a quick and easy way to install any SUSE/openSUSE product on a machine. It doesn't require any boot media and today virtually any system is capable of booting using PXE.

The architecture team maintains a tftp server with boot loaders, boot loader configurations and installation images for a variety of architectures and products. Currently in the Nuernberg office this PXE boot service is only available in the network of the architecture team. Since tftp is unicast, the server should be reachable from anywhere in the internal network. What is missing is the information about the address of the tftp server and the image to boot from this server.

Paul McKenney's blog article inspired me to try apply his approach to kernel's memory allocation flags (gfp_flags) and how their combinations affect the decisions and actions taken during page allocation. Recent upstream development around these flags leads me to believe that the complexity is too high for me to reason about them and change the code without unintended changes in semantics. So it might be worth to let the computer do the hard work.

Continue development of generic job server in haskell with primary focus on continuous integration and later possibly as support tool for data analysis in semantic file storage server, software configuration engine, etc

While in the past MIPS boards were either low-end PIC32 or found in routers running OpenWRT at most, Imagination themselves have recently released the Creator CI20 board (Ingenic, MIPS32) running Debian. And the Shield Pro (previously iGuardian) kickstarter project (Octeon-III, MIPS64) promises to become a playground for testing KVM hardware virtualization.

This project will focus mostly on getting to know the Clojure and ClojureScript ecosystem.

The trend of adopting Web technology in Desktop is ubiquitous these days. Both as a learning project and a proof of concept, we'd like to

Try some things about Docker and Understanding Linux Network Internals

I previously created a semi-auto test script(*) for MOK. The script controls the QEMU virtual machine a pre-setup image and performs two simple test cases. It's tedious to setup the images for every SLE and openSUSE. My goal is to write a script to automatically set up the virtual machines and images and do a full test. I would also like to set up a test for weekly-built OVMF. openQA might be a good reference.
