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

Create a go module to wrap happy-compta.fr by cbosdonnat
Description
https://happy-compta.fr is a tool for french work councils simple book keeping. While it does the job, it has no API to work with and it is tedious to enter loads of operations.
Goals
Write a go client module to be used as an API to programmatically manipulate the tool.
Writing an example tool to load data from a CSV file would be good too.
Cluster API Provider for Harvester by rcase
Project Description
The Cluster API "infrastructure provider" for Harvester, also named CAPHV, makes it possible to use Harvester with Cluster API. This enables people and organisations to create Kubernetes clusters running on VMs created by Harvester using a declarative spec.
The project has been bootstrapped in HackWeek 23, and its code is available here.
Work done in HackWeek 2023
- Have a early working version of the provider available on Rancher Sandbox : *DONE *
- Demonstrated the created cluster can be imported using Rancher Turtles: DONE
- Stretch goal - demonstrate using the new provider with CAPRKE2: DONE and the templates are available on the repo
DONE in HackWeek 24:
- Add more Unit Tests
- Improve Status Conditions for some phases
- Add cloud provider config generation
- Testing with Harvester v1.3.2
- Template improvements
- Issues creation
DONE in 2025 (out of Hackweek)
- Support of ClusterClass
- Add to
clusterctlcommunity providers, you can add it directly withclusterctl - Testing on newer versions of Harvester v1.4.X and v1.5.X
- Support for
clusterctl generate cluster ... - Improve Status Conditions to reflect current state of Infrastructure
- Improve CI (some bugs for release creation)
Goals for HackWeek 2025
- FIRST and FOREMOST, any topic is important to you
- Add e2e testing
- Certify the provider for Rancher Turtles

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.

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.

Updatecli Autodiscovery supporting WASM plugins by olblak
Description
Updatecli is a Golang Update policy engine that allow to write Update policies in YAML manifest. Updatecli already has a plugin ecosystem for common update strategies such as automating Dockerfile or Kubernetes manifest from Git repositories.
This is what we call autodiscovery where Updatecli generate manifest and apply them dynamically based on some context.
Obviously, the Updatecli project doesn't accept plugins specific to an organization.
I saw project using different languages such as python, C#, or JS to generate those manifest.
It would be great to be able to share and reuse those specific plugins
During the HackWeek, I'll hang on the Updatecli matrix channel
https://matrix.to/#/#Updatecli_community:gitter.im
Goals
Implement autodiscovery plugins using WASM. I am planning to experiment with https://github.com/extism/extism
To build a simple WASM autodiscovery plugin and run it from Updatecli

git-fs: file system representation of a git repository by fgonzalez
Description
This project aims to create a Linux equivalent to the git/fs concept from git9. Now, I'm aware that git provides worktrees, but they are not enough for many use cases. Having a read-only representation of the whole repository simplifies scripting by quite a bit and, most importantly, reduces disk space usage. For instance, during kernel livepatching development, we need to process and analyze the source code of hundreds of kernel versions simultaneously.This is rather painful with git-worktrees, as each kernel branch requires no less than 1G of disk space.
As for the technical details, I'll implement the file system using FUSE. The project itself should not take much time to complete, but let's see where it takes me.
I'll try to keep the same design as git9, so the file system will look something like:
/mnt/git
+-- ctl
+-- HEAD
| +-- tree
| | +--files
| | +--in
| | +--head
| |
| +-- hash
| +-- msg
| +-- parent
|
+-- branch
| |
| +-- heads
| | +-- master
| | +-- [commit files, see HEAD]
| +-- remotes
| +-- origin
| +-- master
| +-- [commit files, see HEAD]
+-- object
+-- 00051fd3f066e8c05ae7d3cf61ee363073b9535f # blob contents
+-- 00051fd3f066e8c05ae7d3cf61ee363073b9535c
+-- [tree contents, see HEAD/tree]
+-- 3f5dbc97ae6caba9928843ec65fb3089b96c9283
+-- [commit files, see HEAD]
So, if you wanted to look at the commit message of the current branch, you could simply do:
cat /mnt/git/HEAD/msg
No collaboration needed. This is a solo project.
Goals
Implement a working prototype.
Measure and improve the performance if possible. This step will be the most crucial one. User space filesystems are slower by nature.

Testing and adding GNU/Linux distributions on Uyuni by juliogonzalezgil
Join the Gitter channel! https://gitter.im/uyuni-project/hackweek
Uyuni is a configuration and infrastructure management tool that saves you time and headaches when you have to manage and update tens, hundreds or even thousands of machines. It also manages configuration, can run audits, build image containers, monitor and much more!
Currently there are a few distributions that are completely untested on Uyuni or SUSE Manager (AFAIK) or just not tested since a long time, and could be interesting knowing how hard would be working with them and, if possible, fix whatever is broken.
For newcomers, the easiest distributions are those based on DEB or RPM packages. Distributions with other package formats are doable, but will require adapting the Python and Java code to be able to sync and analyze such packages (and if salt does not support those packages, it will need changes as well). So if you want a distribution with other packages, make sure you are comfortable handling such changes.
No developer experience? No worries! We had non-developers contributors in the past, and we are ready to help as long as you are willing to learn. If you don't want to code at all, you can also help us preparing the documentation after someone else has the initial code ready, or you could also help with testing :-)
The idea is testing Salt (including bootstrapping with bootstrap script) and Salt-ssh clients
To consider that a distribution has basic support, we should cover at least (points 3-6 are to be tested for both salt minions and salt ssh minions):
- Reposync (this will require using spacewalk-common-channels and adding channels to the .ini file)
- Onboarding (salt minion from UI, salt minion from bootstrap scritp, and salt-ssh minion) (this will probably require adding OS to the bootstrap repository creator)
- Package management (install, remove, update...)
- Patching
- Applying any basic salt state (including a formula)
- Salt remote commands
- Bonus point: Java part for product identification, and monitoring enablement
- Bonus point: sumaform enablement (https://github.com/uyuni-project/sumaform)
- Bonus point: Documentation (https://github.com/uyuni-project/uyuni-docs)
- Bonus point: testsuite enablement (https://github.com/uyuni-project/uyuni/tree/master/testsuite)
If something is breaking: we can try to fix it, but the main idea is research how supported it is right now. Beyond that it's up to each project member how much to hack :-)
- If you don't have knowledge about some of the steps: ask the team
- If you still don't know what to do: switch to another distribution and keep testing.
This card is for EVERYONE, not just developers. Seriously! We had people from other teams helping that were not developers, and added support for Debian and new SUSE Linux Enterprise and openSUSE Leap versions :-)
In progress/done for Hack Week 25
Guide
We started writin a Guide: Adding a new client GNU Linux distribution to Uyuni at https://github.com/uyuni-project/uyuni/wiki/Guide:-Adding-a-new-client-GNU-Linux-distribution-to-Uyuni, to make things easier for everyone, specially those not too familiar wht Uyuni or not technical.

pudc - A PID 1 process that barks to the internet by mssola
Description
As a fun exercise in order to dig deeper into the Linux kernel, its interfaces, the RISC-V architecture, and all the dragons in between; I'm building a blog site cooked like this:
- The backend is written in a mixture of C and RISC-V assembly.
- The backend is actually PID1 (for real, not within a container).
- We poll and parse incoming HTTP requests ourselves.
- The frontend is a mere HTML page with htmx.
The project is meant to be Linux-specific, so I'm going to use io_uring, pidfs, namespaces, and Linux-specific features in order to drive all of this.
I'm open for suggestions and so on, but this is meant to be a solo project, as this is more of a learning exercise for me than anything else.
Goals
- Have a better understanding of different Linux features from user space down to the kernel internals.
- Most importantly: have fun.

Enhance setup wizard for Uyuni by PSuarezHernandez
Description
This project wants to enhance the intial setup on Uyuni after its installation, so it's easier for a user to start using with it.
Uyuni currently uses "uyuni-tools" (mgradm) as the installation entrypoint, to trigger the installation of Uyuni in the given host, but does not really perform an initial setup, for instance:
- user creation
- adding products / channels
- generating bootstrap repos
- create activation keys
- ...
Goals
- Provide initial setup wizard as part of mgradm uyuni installation
