Project Description
grog aims to implements a namespaced, distributed map kept alive by an arbitrary number of nodes over a local network.
It uses TCP and UDP multicast.
For a detailed specification see grog's github repository
grog can be implemented in any programming language.
It deals with networking problems in a distributed cluster.
- Possibly useful when developing a distributed application.
- Not designed to be used in production.
- Not meant to be efficient in space.
- Immediate usage.
- Zero network configuration.
- No data definition.
- Arbitrary complex type for values.
- json as unique value's format.
- Small operation set to access and manipulate the map:
get, to get the value of a key from a mapset, to add or update the value of a key in a mapdel, to remove a key, value pair from a map
- Integrable in programs where an implementation for that language exists.
Goal for this Hackweek
Play with Go programming language.
Try to provide a minimum viable deamon and CLI written in Go.

Play with the userfaultfd(2) system call and download on demand using HTTP Range Requests with Golang by rbranco
Description
The userfaultfd(2) is a cool system call to handle page faults in user-space. This should allow me to list the contents of an ISO or similar archive without downloading the whole thing. The userfaultfd(2) part can also be done in theory with the PROT_NONE mprotect + SIGSEGV trick, for complete Unix portability, though reportedly being slower.
Goals
- Create my own library for userfaultfd(2) in Golang.
- Create my own library for HTTP Range Requests.
- Complete portability with Unix.
- Benchmarks.
- Contribute some tests to LTP.

A CLI for Harvester by mohamed.belgaied
Harvester does not officially come with a CLI tool, the user is supposed to interact with Harvester mostly through the UI. Though it is theoretically possible to use kubectl to interact with Harvester, the manipulation of Kubevirt YAML objects is absolutely not user friendly. Inspired by tools like multipass from Canonical to easily and rapidly create one of multiple VMs, I began the development of Harvester CLI. Currently, it works but Harvester CLI needs some love to be up-to-date with Harvester v1.0.2 and needs some bug fixes and improvements as well.
Project Description
Harvester CLI is a command line interface tool written in Go, designed to simplify interfacing with a Harvester cluster as a user. It is especially useful for testing purposes as you can easily and rapidly create VMs in Harvester by providing a simple command such as:
harvester vm create my-vm --count 5
to create 5 VMs named my-vm-01 to my-vm-05.
Harvester CLI is functional but needs a number of improvements: up-to-date functionality with Harvester v1.0.2 (some minor issues right now), modifying the default behaviour to create an opensuse VM instead of an ubuntu VM, solve some bugs, etc.

Help Create A Chat Control Resistant Turnkey Chatmail/Deltachat Relay Stack - Rootless Podman Compose, OpenSUSE BCI, Hardened, & SELinux by 3nd5h1771fy
Description
The Mission: Decentralized & Sovereign Messaging
FYI: If you have never heard of "Chatmail", you can visit their site here, but simply put it can be thought of as the underlying protocol/platform decentralized messengers like DeltaChat use for their communications. Do not confuse it with the honeypot looking non-opensource paid for prodect with better seo that directs you to chatmailsecure(dot)com
In an era of increasing centralized surveillance by unaccountable bad actors (aka BigTech), "Chat Control," and the erosion of digital privacy, the need for sovereign communication infrastructure is critical. Chatmail is a pioneering initiative that bridges the gap between classic email and modern instant messaging, offering metadata-minimized, end-to-end encrypted (E2EE) communication that is interoperable and open.
However, unless you are a seasoned sysadmin, the current recommended deployment method of a Chatmail relay is rigid, fragile, difficult to properly secure, and effectively takes over the entire host the "relay" is deployed on.
Why This Matters
A simple, host agnostic, reproducible deployment lowers the entry cost for anyone wanting to run a privacy‑preserving, decentralized messaging relay. In an era of perpetually resurrected chat‑control legislation threats, EU digital‑sovereignty drives, and many dangers of using big‑tech messaging platforms (Apple iMessage, WhatsApp, FB Messenger, Instagram, SMS, Google Messages, etc...) for any type of communication, providing an easy‑to‑use alternative empowers:
- Censorship resistance - No single entity controls the relay; operators can spin up new nodes quickly.
- Surveillance mitigation - End‑to‑end OpenPGP encryption ensures relay operators never see plaintext.
- Digital sovereignty - Communities can host their own infrastructure under local jurisdiction, aligning with national data‑policy goals.
By turning the Chatmail relay into a plug‑and‑play container stack, we enable broader adoption, foster a resilient messaging fabric, and give developers, activists, and hobbyists a concrete tool to defend privacy online.
Goals
As I indicated earlier, this project aims to drastically simplify the deployment of Chatmail relay. By converting this architecture into a portable, containerized stack using Podman and OpenSUSE base container images, we can allow anyone to deploy their own censorship-resistant, privacy-preserving communications node in minutes.
Our goal for Hack Week: package every component into containers built on openSUSE/MicroOS base images, initially orchestrated with a single container-compose.yml (podman-compose compatible). The stack will:
- Run on any host that supports Podman (including optimizations and enhancements for SELinux‑enabled systems).
- Allow network decoupling by refactoring configurations to move from file-system constrained Unix sockets to internal TCP networking, allowing containers achieve stricter isolation.
- Utilize Enhanced Security with SELinux by using purpose built utilities such as udica we can quickly generate custom SELinux policies for the container stack, ensuring strict confinement superior to standard/typical Docker deployments.
- Allow the use of bind or remote mounted volumes for shared data (
/var/vmail, DKIM keys, TLS certs, etc.). - Replace the local DNS server requirement with a remote DNS‑provider API for DKIM/TXT record publishing.
By delivering a turnkey, host agnostic, reproducible deployment, we lower the barrier for individuals and small communities to launch their own chatmail relays, fostering a decentralized, censorship‑resistant messaging ecosystem that can serve DeltaChat users and/or future services adopting this protocol

go-git: unlocking SHA256-based repository cloning ahead of git v3 by pgomes
Description
The go-git library implements the git internals in pure Go, so that any Go application can handle not only Git repositories, but also lower-level primitives (e.g. packfiles, idxfiles, etc) without needing to shell out to the git binary.
The focus for this Hackweek is to fast track key improvements for the project ahead of the upstream release of Git V3, which may take place at some point next year.
Goals
- Add support for cloning SHA256 repositories.
- Decrease memory churn for very large repositories (e.g. Linux Kernel repository).
- Cut the first alpha version for
go-git/v6.
Stretch goals
- Review and update the official documentation.
- Optimise use of go-git in Fleet.
- Create RFC/example for go-git plugins to improve extensibility.
- Investigate performance bottlenecks for Blame and Status.

terraform-provider-feilong by e_bischoff
Project Description
People need to test operating systems and applications on s390 platform.
Installation from scratch solutions include:
- just deploy and provision manually
(with the help of ftpbootscript, if you are at SUSE) - use
s3270terminal emulation (used byopenQApeople?) - use
LXCfrom IBM to start CP commands and analyze the results - use
zPXEto do some PXE-alike booting (used by theorthosteam?) - use
tessiato install from scratch using autoyast - use
libvirtfor s390 to do some nested virtualization on some already deployed z/VM system - directly install a Linux kernel on a LPAR and use
kvm+libvirtfrom there
Deployment from image solutions include:
- use
ICICweb interface (openstackin disguise, contributed by IBM) - use
ICICfrom theopenstackterraformprovider (used byRancherQA) - use
zvm_ansibleto controlSMAPI - connect directly to
SMAPIlow-level socket interface
IBM Cloud Infrastructure Center (ICIC) harnesses the Feilong API, but you can use Feilong without installing ICIC, provided you set up a "z/VM cloud connector" into one of your VMs following this schema.
What about writing a terraform Feilong provider, just like we have the terraform libvirt provider? That would allow to transparently call Feilong from your main.tf files to deploy and destroy resources on your system/z.
Other Feilong-based solutions include:
- make
libvirtFeilong-aware - simply call
Feilongfrom shell scripts withcurl - use
zvmconnectorclient python library from Feilong - use
zthinpart of Feilong to directly commandSMAPI.
Goal for Hackweek 23
My final goal is to be able to easily deploy and provision VMs automatically on a z/VM system, in a way that people might enjoy even outside of SUSE.
My technical preference is to write a terraform provider plugin, as it is the approach that involves the least software components for our deployments, while remaining clean, and compatible with our existing development infrastructure.
Goals for Hackweek 24
Feilong provider works and is used internally by SUSE Manager team. Let's push it forward!
Let's add support for fiberchannel disks and multipath.
Goals for Hackweek 25
Modernization, maturity, and maintenance: support for SLES 16 and openTofu, new API calls, fixes...

Hacking a SUSE MLS 7.9 Cluster by roseswe
Description
SUSE MLS (Multi-Linux Support) - A subscription where SUSE provides technical support and updates for Red Hat Enterprise Linux (RHEL) and CentOS servers
The most significant operational difference between SUSE MLS 7 and the standard SUSE Linux Enterprise Server High Availability Extension (SLES HAE) lies in the administrative toolchain. While both distributions rely on the same underlying Pacemaker resource manager and Corosync messaging layer, MLS 7 preserves the native Red Hat Enterprise Linux 7 user space. Consequently, MLS 7 administrators must utilize the Pacemaker Configuration System (pcs), a monolithic and imperative tool. The pcs utility abstracts the entire stack, controlling Corosync networking, cluster bootstrapping, and resource management through single-line commands that automatically generate the necessary configuration files. In contrast, SLES HAE employs the Cluster Resource Management Shell (crmsh). The crm utility operates as a declarative shell that focuses primarily on the Cluster Information Base (CIB). Unlike the command-driven nature of pcs, crmsh allows administrators to enter a configuration context to define the desired state of the cluster using syntax that maps closely to the underlying XML structure. This makes SLES HAE more flexible for complex edits but requires a different syntax knowledge base compared to the rigid, command-execution workflow of MLS 7.
Scope is here MLS 7.9
Goals
- Get more familiar with MLS7.9 HA toolchain and Graphical User Interface and Daemons
- Create a two node MLS cluster with SBD
- Check different use cases
- Create a "SUSE Best Practices" presentation slide set suitable for Consulting Customers
Resources
- You need MLS7.9 (Qcow2) installed + subscription
- KVM server with 2 KVMs, 2 SBD
- RHEL7 and HA skills
Add a machine-readable output to dmidecode by jdelvare
Description
There have been repeated requests for a machine-friendly dmidecode output over the last decade. During Hack Week 19, 5 years ago, I prepared the code to support alternative output formats, but didn't have the time to go further. Last year, Jiri Hnidek from Red Hat Linux posted a proof-of-concept implementation to add JSON output support. This is a fairly large pull request which needs to be carefully reviewed and tested.
Goals
Review Jiri's work and provide constructive feedback. Merge the code if acceptable. Evaluate the costs and benefits of using a library such as json-c.
