We had a quick course of Coccinelle during the last Labs conference. The tool is really great and I would like to explore possibility of checking lock invariants for particular functions. Julia was really prompt and implemented something that should help but I didn't get to it since the conference.

From the kernel-source git repository for SUSE kernels we can extract the people who backported a patch and the files a patch touches. Use this information to build a database for which paths are touched by which developers and write a tool to find the most relevant people for a given source path or upstream patch.

The result for xfstests in osd seems always red[1], but actually it's only a few test fail in a group(around 1/50). If we want to keep use openQA to handle those test, we need some enhancement for that. Try to enhancement test result to make it shows in a better way. - Make more reasonable group for those test

Diagnosing issues with stalling desktop application (or a whole desktop environment) is difficult these days as the application often requires multiple processes interconnected with sockets, pipes, futexes, etc. to work and often it is not clear which process is the one responsible for blocking the whole ecosystem. The idea of this project is to write a tool that gathers information about processes in the system and for each process that is sleeping display the resource (file, socket, futex) it is waiting on as well as the process that is likely responsible for unblocking (feeding pipe, sending data to socket, unlock futex, ...). Once the information is gathered, we can also plot it for graphical displaying with tools like graphviz.

Just have play with bpftrace on some real kernel bugs.

If you want to use the full potential of SSDs as primary (and possibly only) storage on SLE or openSUSE systems, you are supposed to perform several configuration settings to make it fly, including:

in https://gohugo.io/ you can easily write custom themes via templates for creation of static websites

There are many fun peripherials that you can connect to a RPi but PC users are not left out either

Moving objects to a new container is a problem everyone in R&D has faced at least once in his life. It requires a very advanced algorithm to pack the many different objects (which are generally heterogeneous, with different uses, types, weights and sizes), before the packs can then be transferred to the new container, generally through a dedicated bus. We can identify some usual cases:

[MTUI][MTUI] is a tool used by QA-Maintenance in testing maintenance updates. Saddled with a host of questionable choices for its interfaces and implementation, it includes a number of difficult-to-fix bugs and hostility toward change. While not the first choice for me, the time's come to scout out a different approach. Welcome SMRT.

toptop is a clone of Linux's top CLI tool, but written in Go.

http://squarefootgardening.org/ is a form of intensive gardening that packs plants closely together. It depends on companion planting to encourage growth and protection for pests.

I switch fairly often from working on my laptop alone to working on my laptop attached to the dock with several monitors, and I have to move my windows around every time I switch. I want a tool to save and load window/desktop location configurations. I've tried a few tools and scripts that either haven't worked or haven't worked to my liking. I propose to create a tool that will work for openSUSE.

It ain't rocket science, it ain't thrilling, it's just useful.

Solid Ground is an essential software tool for the daily tasks of an L3 agent. A continuous integration/continuous delivery (CI/CD), and even more a continuous deployment, approach is currently missing from its development ecosystem slowing down its release cycles.

Add MOKx for blacklisting any specific hash of kernel module.

boot: to find logs with both kernel and user-space parts, be able to add debug flags etc. to the failing service configuration... suspend/resume: what services are configured? Something triggered via DBus? How to find? And how to debug that?

zypp-gui is a gui tool to update the system and install the packages in openSUSE distro. It's written by rust.

It is fabulous to get machines from cloud for automation testing, and there are lots of things to learn in cloud. So I will start the cloud journey in this hackweek, to learn suse cloud architecture, various technologies inside cloud, and try to deploy one.

Back in the day, I enjoyed coding on 8 bit machines, mostly MSX. There is now a Kickstarted project to create a successor machine with some new features: hardware sprites, hardware scrolling, better sound, integrated SD/MMC IO and an ESP8266 for networking.

(Improve last hackweek's project.)

XFCE currently has no support for monitor hotplugging, which makes it hard to use on Laptops with docking stations. This project wants to add support to XFCE to automatically adjust its display setup when the monitor configuration changes.

There is quite a popular Android software for connection OBD standard adapters but not for older, brand specific ones. One for pre 2001 VAG cars is this one:

Current virtualization requirements mainly come from fate, and I haven't got chance to try freely many features of qemu/libvirt. So I will try to play it.

Since my mailbox has migrated to office365 mailbox a couple of weeks ago, I tried to optimize my tool chain to sync my mail and calendar and integrate to the gnome-shell (calendar, notification). So far I am comfortable with such a set and gonna use 2-3 hours in hackweek to summarize the practice of combining the following tools in written format:

Investigate possibilities for the distributed builds for Ceph to speed up builds.

Working on a way to add exceptions using javascript (jquery), php, json, and mysql to modify the generated calendar used to manage who is on after hours.

Although I've been maintaining CRIU package, I had little time to play with it recently. It's still interesting especially in combination with various containers. So let's spend (or waste) some time.

Since I'm a maintainer of Gnome-Logs, I'd like to hack on Gnome-Logs. During the hack week I'll focus on the bug 753471 of Logs.

As title says, I want to finish the Windows Subsystem for Linux images of SLES and Leap 15, which Fabian Vogt provided, so they can be shipped to the Windows Store.

People are interested in Linux on Windows via WSL, especially given the new fully virtualized Linux kernel in WSL 2. It's interesting to know whether registered SUSE installations might be running in WSL as opposed to other Microsoft virtualization platforms, but the current approach taken by SUSEConnect (the client for SUSE Customer Center) does not permit this.

Sonnenhut is a simple Pythong web app that provides basic info useful for planning photographic activities. The current iteration does the job, but it can be improved and extended in a number of ways.

In a quite natural and steady way, all my relatives (wife, kids, mother, aunt...) have adopted openSUSE in their computers. There is only one resistance spot. My father's computer (HP+Windows8) implements all kind of mechanisms to avoid dual boot.

Compared with traditional file systems (e.g. EXT4, XFS), log-structured file systems treat its storage as a circular log and write sequentially to the head of the log. I want to learn about this kind of file system via this hack week, to understand how it manages its data and metadata, to understand how it recover back from crash, to understand its advantages and disadvantages.

What if Salt Minions no longer need to specify the IP or DNS address for the Master? Or even better: Master(s) can call minions. Of course, for the beginning, we would assume the network is trusted. But we should be able to add further security checks (keypairs etc).

provide a summary report of data from a sar data file.

The incredible Neal Gompa has packaged Open Shift Origin (RH's core Docker + Kubernetes stack) for openSUSE

The plan is to implement a safe path resolution library for Linux to avoid the plentiful numbers of security vulnerabilities that have been seen in the wild related to path resolution race conditions and various other attacks. I've been working on kernel-space solutions but even if they were merged, it is difficult to use them safely directly. So this library intends to provide simple wrappers that everyone can use.

Trimatik MC is an older heating control from Viessmann. It has no supported digital interface for remote access, but I found at least two ways to get access to sensor data like various temperatures and state of relay contacts. One way is to use the so called remote control the other use the clock timer. This project will use the latter way, because the hardware adaption is much easier and and all four timer channels could be controlled as well. Remote access will be done via an ESP32, which emulates the clock timer and gets/pushes data via WIFI.

There are a number of items related to doing Virtualization CI and testing which I have a hard time getting to during my day job. I'll take Hackweek as an opportunity to get at least a little out of my normal space and improve our methods. This mainly focuses on QEMU/KVM and some of the efforts and infrastructure I've already got in various states of development, or at least investigation.

DRBD refers to block devices designed as a building block to form high availability (HA) clusters.Also possible to combine multiple devices driver for Linux(MD) and the network block device(NBD) to achieve similar functionality.

I would like to take part in the course that is offered at https://suse-academy.hastexo.com/

Having done only very little with openQA in the past I would like to learn more about it. I would like to start writing a test suite for profanity.

Collecting problems and writing tools or methods for kernel debugging.

The basic idea behind learning language is to ensure three parts:

Play with Docker orchestration tools like the ones provided by CoreOS, OpenShift and kubernetes. Provide packages for openSUSE and SLE.

We currently work on a consistency model for upstream livepatching infrastructure. We use something called a fake signal to speed up a finalization of the patching process. I'll port the implementation to kGraft in SLES which should allow to remove immediate patching since it has recently proved to be problematic...

I have an IRC tab open in pidgin and an adjacent XMPP tab; the latter one displayed with focus. When a new XMPP tab opens in background (with a message incoming), the IRC tab steals the focus but not the display. It brings annoying situations when I sometimes send something accidentally to the IRC instead of XMPP, not noticing that I don't have focus.

Ceph is very robust for keeping data, beside using cephfs or exporting rbd. It is not too easy to access object directly with a client, let alone mobile. By using Rados gateway, android client can easily using S3/Swift http/s request to read object data from the internet.

Retty is a tool for changing stdin,stdout,stderr of a running process (http://pasky.or.cz/dev/retty/) which may be handy if you want to attach to a process running e.g. from a died ssh session, changing running process to run from under screen(1) etc.. Currently it doesn't work for 64-bit systems and it doesn't handle changing of a controlling tty of a process (which may be possible using setsid() and opening a new tty). The aim of this project it to fix the above deficiencies and package the tool in OBS.

We from the public cloud dev team regularly upload generic and product images to be available in public cloud systems like Amazon EC2, Google Compute Engine or Microsoft Azure. The task of uploading stuff there is not only about having the tools it's also about having the right environment which provides account credentials as well as access to the image when they are built in the buildservice. Also the location from where the upload happens can make a difference in performance.

Project Description

RabbitMQ is, in this hacker's opinion, hard to run, hard to scale, hard to debug, and difficult to run in a HA situation. ZeroMQ takes a different approach from the centralized broker model, and instead runs a daemon on every machine that needs to send or receive message over the bus, and communicates directly between machines.

This is somehow related with our team's work(https://fate.suse.com/323437), We want to write a set of restful API for any components in HA product stack use to control the cluster.

My first hands-on machine learning using scikit-learn and tensorflow. If there is time in the end i would like to implement it into one of my existing projects by maybe processing some sensor data.

Project description

With many Proof of Concepts (PoCs) going on for SUSE Cloud, the development team has observed that we have no clear path on how Sales Engineers (SEs) and sometimes dedicated support engineers (xSE) can receive technical support to successfully complete the projects, often leading to escalation calls and even firefighting on-site visits by developers. Goal of that project is to come up with a best practice guide and to eventually set expectations on what's possible from a development point of view. Results should be documented in a central internal location and announced to all relevant parties.

I'd like to explore the creation of a source service to help vendoring the dependencies for an Elixir project.

VOVO is a server-client architecture to determine current abuild load on devel-network machines. The goal is to trigger machines on and off depending on build power. It is an attempt to reduce power consumption.

take my existing buildit.sh script (https://github.com/dmbyte/SES-scripts/blob/master/clusterbuilder/) and enhance it to be more of the installer experience needed.

Spacewalk is the upstream project of SUSE Manager.

The evfilter project (https://github.com/lhc4/libevfilter/) isn't able to substitute multiple events to one event or vice versa. I want to improve that and repair some other bugs.

The disassembly in gdb is not ideal. The binding with source code lines is weird (even crash, which does use gdb beneath, does that better), I don't see the jump targets; furthermore, there's a lot more informations hidden in the DWARF2 which may be of some interest - like which code is inlined, or which register/stack address should contain some variable.

Since this will be my first real "from the start" publication the goal for me has more to do with the experience of publishing the projects, use of the public hosting site and access tools, particularly git.

The goals: - Learn enough Java fundamentals to understand OpenDaylight code

Currently the main complaint people have about OCI tooling is the lack of a transition from Docker to OCI. With umoci you have a lot of low-level image configuration abilities, and skopeo and runC cover the other major parts of the picture, but you need something to tie them together.

I tried to work blockchain into this, just so we could cover the trifecta of buzz words. Sadly I could not maintain saintly and do this.

kCFI is a tool that enables the compilation of commodity Operating Systems with Control-Flow Integrity protection. kCFI first prototype was developed/implemented during a PhD program held in the University of Campinas, in Brazil. Although fully functional, the tool remains in a very experimental shape, needing to be refactored prior to being released.

Create a tool which will make it possible to monitor the lifecycle of pods in a kubernetes cluster (as well as other types of tabular or structured data), and provide a convenient user interface for viewing and interpreting that data. This will be useful in development and testing of our kubernetes-based container platform (Cloud Application Platform), as it will allow us to better understand where things are going wrong when we encounter component failures.

The current kplex_monitor repo needs to be reorganized so that it can be installed from scratch on another PI using ansible

The zypprepo was written around 3 years ago, and was based on the yumrepo built-in type/provider. Nowadays zypprepo misses a lot of functionality, which will be automatically inherited if it gets rewritten to be in sync with the current code of yumrepo (as also discussed in its issues #5 and #9). If time permits, solving issue #4 would be also really useful.

I want to use this week to familiar with the SUSE products that i don't have time/chance to participate. For instance, SUSE Cloud, SUSE storage, Docker etc... Just like the presentations in SUSEcon 2015 closing keynote.

A nice project for enhancing the winter time:

As live migration is widely used in many scenarios nowadays, spend one week time to study it and try to improve its efficiency, e.g. seamlessly migrate with less downgrading the guest. Another challenging part is memory migration, as it involves the dirty memory's detection, record and copy.

Rationale:

bundler-audit is an open source that scans you Gemfile.lock (if you program with ruby) for known vulnerabilities.

Metadata project provides testsuites as a service. Slenkins test wants to use metadata but requires two new fields. I will add nodes and incompatible two new fields.

During testing virtualization , I usually met some issue and can not position the issue location (host or guest), so I would like to deeply learn QEMU code, card the work flow, understand communication mechanism between host and guest.

Currently, each filesystem developer does his fstests runs (a testsuite for regression-testing of filesystems) on his dedicated test machine, on Orthos machine, ... This not only means duplication of efforts to automate this testing but also leads to inefficient use of resources (sometimes the test machine is just idle, sometimes you would need more tests to run in parallel to speed up development). The goal of this effort is to use SUSE Engineering Cloud to implement fire-and-forget fstests runs where you specify kernel to test (fetched from git tree or so), fstests configs to run, and then just pick up test results later on...

Description

There's already an app but code/features already in Syncthing Tray could be reused to create a nicer app with additional features like managing ignore patterns more easily. The additional UI code for the app could then in turn be re-used by other parts of Syncthing Tray, e.g. to implement further steps in the wizard as requested by some users. This way one "UI wrapper codebase" could serve GNU/Linux, Windows and Android (and in theory MacOS) at the same time which is kind of neat.

This project is about using Salt SSH for managing systems without the need of an additional agent to be installed (besides sshd). With the SSH protocol the connection is initiated by the management server, thus Salt SSH can be used to even manage systems that are located outside of company firewalls, i.e. machines that cannot access a salt-master due to firewall restrictions.

Project Description

There are lots of interesting presentations happening all throughout SUSE on all manner of subjects. Presenters have found all kinds of creative ways to showcase their content using different shapes, templates, and other tools to convey important information. If you're looking to start a new presentation, the current slide templates are great to get started with but often time presenters have to look elsewhere for design inspiration. The goal of this project is to create a centralized "extended catalog" of Powerpoint and Impress templates, as a compliment to the existing templates, and make them available to SUSE employees through ImageRelay, that can serve as inspiration and templates for those looking to create rich and complex presentations based on examples built by fellow SUSE employees.

kGraft is SUSE Labs answer to the rising need for being able to patch the running kernel without rebooting the system. I think this kind of tool is very cool, so by this hackweek chance, I want to investigate it how it works and how it was implemented. And also by this chance, I hope I can improve my ability of kernel hacking. If you are also interested in kernel live patching, please join this project together.

since i am learning golang, i will make some contributions for the upstream project we used already @suse

SUSE CaaS Platform is a Cloud-Native Computing Foundation (CNCF) certified Kubernetes distribution.

Using the camsource and vlc packages as an example. If camsource is configured to use a given dev/video[n] device with a choice of resolution in the width and height fields of a camsource conf file then if camsource is the first application to access the device captured images are as-expected. However, if an application like vlc is used for the same device (and exited) before starting camsource (e.g. to check the view from the camera before starting camsource) and if the camera supports higher resolutions than used in the camsource configuration what occurs is that camsource will not setup the camera to use the configured resolution and has a broken view of the camera output based on the vlc chosen resolution chopped to the camsource configuration. For example, with camsource configuration set to use 640x480 on a camera that supports 720x480 and vlc is used and exited before camsource is started then the captured camsource images contain two non-continuous partial image blocks with a horizontal border dividing them. I assume either vlc fails to fully reset the device configuration when exiting or camsource fails to initialize the device "from scratch" when starting. The two applications use different video device APIs but the setup and cleanup for the camera in each case is a very limited part of the application's functionality.

I'm totally new in k8s, when I hear Rancher's product in all-hands I couldn't image what's that is. I'd like to take some time to learn some basic knowledge about k8s and Rancher's products.

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.

I recently bought a Lioncast LK200 RGB keyboard which is a nice piece of hardware and has exactly the look and feel I want. All basic functions work well under Linux. Unfortunately the manufacturer only provides user software to upload/download profiles and control the LEDs for Windows. The device can be configured and operates autonomously from any OS but color setup is a PITA and it's very easy to factory-reset, and lose all config.

Description

Improve UML handling of segmentation faults in kernel mode. Although such page faults are generally caused by a kernel bug, it is annoying if they cause an infinite loop, or panic the kernel. More importantly, a robust implementation allows to write KUnit tests for various guard pages, preventing potential kernel self-protection regressions.

I want to use this Hackweek to explore (Functional) Reactive Programming to be able to use it in my day-to-day work.
