Once again, the SUSE band is coming together to make music and we're planning a party this time round!!! We have a band name :-)

New Development In previous hack weeks, the first few days ended up being wasted on just getting it working. I'm pleased to share that the code quality has improved dramatically since the last hack week and there are now extensive test cases for both unit testing and testing against real vmcores, and we'll use both mypy and pylint (if installed) to perform static analysis. Packages for those are available in openSUSE or as part of the crash-python OBS repo for SLE15. It has been tested with kernels from 3.0 to 5.1.

As every hackweek, lets package/update/cleanup some stuff fore factory: Update/package:

The idea behind the project comes from recent work on integration of OpenDayLight with Suse OpenStack Cloud 6/7. The goal for this Hackweek project is to realize a demonstrable NFV use-case on Suse OpenStack Cloud with as much reduced manual orchestration as possible. The use-case to consider is to run a Service Function Chain(SFC) with basic Network functions like Firewall/QoS that run as services on JeOS Guests on SUSE OpenStack Cloud (SOC).

Orcas are amazing animals. They are playful, intelligent, great swimmers, and very social. They also love to play with their food, hunting down their prey with advanced strategies - understanding where its prey hides, how it will try to escape, and how to overcome those tactics - and having a lot of fun doing so, before relentlessly tearing it apart, killing it, and eat it. Not necessarily in that order. Oh, and they have the right color scheme. This forces their prey to also improve and adapt more advanced strategies and tactics. In this arms race, both sides evolve and improve: the evolutionary pressure has made cephalopods highly intelligent, adaptable, and resilient. Unfortunately (for them), they are still very tasty. So we should exert more evolutionary pressure on individuals to help them stay alive as a species.

This is the tool I've been working on since HW11 and it needs more work. Actually, there's always something which could be done on it. It is basically an x86 instruction decoder with special emphasis on the kernel and decoding interesting pieces of it in order to help in the development of low-level patching techniques, among others. git repo: https://gitlab.suse.de/bp/x86d

Description

It can boot up from udisk/floppy.

Currently, the usual way to communicate with VM instances in the cloud from outside is ssh. This is okay for most uses, but a) does not work when you mess up with the guest's ability to network and b) requires a free floating IP. I wonder if, for qemu/kvm instances, it would be possible to use virtio-serial possibilities : from the guest, it is seen as a serial port, and from the outside, it is seen as a UNIX socket, or as something else. It is fast, as it does not go through virtualization and device drivers.

PXEAT (stand for PXE Administration Tool) is a tool to easily deploy and manage PXE service. It's NOT a tool for automatic deployment. It can enable user to add their own PXE items by themselves, but of course, very limited for security reasons. The tool will be developed with the light-weight framework - flask, as well as a sqlite database.

DAPS is the tool used by the SUSE documentation team to generate HTML, ePUB, PDF, ... output of the SUSE manuals from DocBook XML sources. It uses the suse-xsl-stylesheets for this purpose. Currently three different suse-xsl-stylesheet brands exist: SUSE, DAPS, openSUSE. Branding is done by adjusting the xsl-stylesheets directly. It would be desirable to be able to easily change the branding, e.g. via a simple config file in the style of /etc/sysconfig files, since most people cannot hack XSLT. This is also the number one enhancement request we get from DAPS users outside of SUSE.

openvswitch is used by cloud infrastructure (e.g. OpenStack) and software defined networking stacks, often in conjunction with KVM and Xen compute resources. When creating workloads on KVM compute resources, orchestration services can specify the openvswitch interfaceid and port-profile of the workload's virtual interface(s). E.g. orchestration can create workload configuration containing

Read in a crash or oops-style backtrace and access DWARF information to output the current content of the stack and registers in term of symbols, and the the crash commands to dump/pretty print them. In other words, when looking at a crash dump, answer the questions "Which variable is currently stored in $rax? What is the structure of the stack? Which variable is stored at $rsp+16?"

Status at the end of hackweek 10

Make a final attempt to implement a graphical user interface for grub2 (gfxboot2).

It's quite some work, unfortunately. Here's what's done so far:

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. Porting openSUSE to MIPS will involve setting up an OBS instance linked to Factory (update: done) and cross-compiling a set of packages for an initial bootstrap (update: in progress). Maybe this can be scripted to some degree, as there will be some overlap with the ARM ILP32 port project.

This is about porting the old KDE 3 based KDirstat to the latest Qt 5. KDirStat didn't use that much KDE infrastructure to begin with, and KDE seems to be more and more a moving target. Project repo and web site with more details:

Linux Certification Preparation Preparation for different Linux Certification:

Distributed teams, cultural differences, expectations and habits are a natural enemy of vibrant, productive meetings (yes, meetings can be productive!). In this project I'd like to work on a different format and targeted exercises to provide ideas and a resource library to anyone interested in spicing up stale meetings. I am looking for your ideas, problems and examples - Feel free to join!

The idea is about an easy way to allow users to make upgrades (e.g.: changing from one major version like 15.0 to version 15.1) using a GUI and as easy as they can in Ubuntu. Something like a notification with a button to perform the upgrade with just one-click, instead of having to deal with the terminal, that frights some new users and gives them the sensation of an outdated system.

Last time I checked QEMU lacked support for >= z10 processors. Thus one cannot run SLE12 and newer in a virtual machine on non-s390x host. I'd like to improve the situation during Hackweeks.

To make OpenQA work with real ARM devices, we need to control * Reset

As DBus a main component in Linux user space, in this hackweek I plan to learn more about it. Tentative Plan: a node js binding for sd-bus interface offered by systemd (available in SLE12)

YaST code organization is a mess at many levels (files location, namespaces, code dependencies...). Recently we created this gist to put some of the issues on the table Many YaST developers will be at openSUSE Conference, that overlaps with Hackweek. The plan is to lock them all in a room with a blackboard and reach agreements on how the code should be organized in the future. Then use Hackweek to iron the details, document everything in some kind of style guide and, if time permits, even do some experiments about how to adapt the existing code to the new conventions.

This project aims for enabling FCoE over virtio-net. With that we should be able to run FCoE within a KVM guest, and finally have a 'real' FC host in a KVM guest. This should enable 'real' FC testing, like link failure, multipath operations etc.

Right now, every time a new team wants a new room in our Jangouts instance, they have to ping me and I have to manually create the room. That means: * Adding some lines to the corresponding config file

The current Jangouts UI is limiting us when thinking about adding new features. Some examples: * This (using the whole thumbnail to pin a participant) was implemented, but the result is far from optimal (I have not even deployed it in production).

Our previous efforts to enable gdb to open kdumps was not received in upstream as well as we hoped for. The perhaps-acceptable way would be to extend gdb with the possibility of implementing targets in Python, then create example binding to libkdumpfile (which already got a Python binding). We've already tried that, yet it has to be tidyed up. So this project aims at:

Clair is a static vulnerability analyzer for containers. Currently it supports containers based on Debian, Ubuntu and RedHat. I already started this project on the CSM workshop, now I want to finish the integration for openSUSE and SLES based container images. You can track the changes at https://github.com/coreos/clair/pull/199.

Flatpak (previously known as xdg-app) is a bundle system, based on ostree, to easily make available applications bundle to users. Currently, flatpack is available on openSUSE Tumbleweed but we don't ship any runtime based on openSUSE (freedesktop or GNOME runtime). Also, it could be interesting to generate flatpak bundle directly from OBS, if possible, using either available packages or directly application sourcecode.

I've attempted this several times already and each attempt had different shortcomings. I'm kind of curious about how exactly will I fail this time. And it looks like I haven't failed this time.

Tigervnc comes with two very similar VNC viewers - one written in C++ and one in java. The java one can be embedded in a webpage as a java applet. We use that in our default VNC setup (the one enabled in YaST). That way if user doesn't have VNC viewer installed, browser is enough. However running java applets in browser is getting harder every day. Especially when the applet isn't signed by a trusted authority.

To make sure openSUSE can coexist nicely with an existing Windows installation, we need to have automated regression testing. UEFI and secure boot are especially interesting.That means installing Windows and openSUSE in parallel in openQA. Instead of just uploading some prepared hard disk image, openQA should ideally install Windows itself and save the generated image. In a second run openQA can then install the latest Leap or TW on that disk image.

Automation tools are our emotional friends. Know each other deeper and improve it, it's a way to be harmonious for our friendship. 1. SLEnkins

• Build zookeeper, mesos-master and mesos-slave on SLE12
• Setup a 3-nodes high-availability cluster (zookepper + mesos-master + mesos-slave run on each node)

L3 bug reproduction often requires becoming the admin for a moment. I'd like to write down some nifty tricks I used to get certain “interesting” system configurations to work.

In Beijing HA server room, we have a Huawei switch with a 10GB bandwith uplink FC port, a iSCSI HBA, a desktop computer, and some SFPs, I will build a 10GB bandwith iscsi server.

Create a console application for a crossword puzzle generator that can be fed with a custom list of word+explanation pairs. It may be used by people to quickly familiarize with a specific topic (e.g. a knowledge area, new hires to the company ...) to at least understand the terminology and the abbreviations that are used. Or to just have some distraction and fun :-) I think it consists of three components:

QA wants to set up a new QA Portal to get an new organized entry point for all Information that is QA related. The Hackweek Project is to start a discussion with the different QA groups, SLE QA, CSS QA and QAM to collect ideas and make a concrete plan.

There is a super cool framework for mobile phone apps available: ionic (http://ionicframework.com/) ionic allows you to write apps in HTML, (Angular) JavaScript, and TypeScript for any mobile phone platforms: iOS, Android, and Windows Phone. You just need to know how to use HTML and JavaScript and you can start writing an app and convert it to any mobile phone platform.

Together with my son, I'm working on improving the Salt support in Manager 3. The idea is inspired by SUSE OpenStack Cloud's Crowbar tool:
