0WM — Measure and visualize Wi-Fi coverage

Wi-Fi coverage is key in corporate and BYOD environments, as the mobility offered by wireless protocols often outweighs criteria such as speed and stability, offered by wired alternatives. These criteria are however critical to guarantee a suitable quality of service, and reliable options to help network operators are scarce and unaffordable to small organizations. 0WM will provide feature-rich tools to produce quality coverage maps, leveraging affordable COTS components, to quickly and efficiently identify coverage problems affecting end users.

Hardware 2D graphics engine — Additional functionality and better performance for FPGA-based 2D video controller

This project is to develop hardware accelerated 2D display controller boards for easily adding interactive user interfaces to single-purpose industrial and commercial machines.

Traditionally, to make stand-alone machines and systems (i.e. not based on PCs but on custom computing boards), if developers need to provide a high resolution graphical user interfaces (GUI) they are offered only two inconvenient options: use a complex system like a Linux-capable single board computer, or limit performance to low resolutions that are unsuitable for medium to large displays. The latter case simply prevents successfully marketing those products, while the former requires a high degree of qualifications in embedded systems development, where the requirements are simple products like signage systems or vending machines.

The controller boards (CPU and FPGA based, released as open hardware) are capable of loading previously stored images (lossy or lossless), plus movies, fonts and other resources required. The drawing commands are implemented with hardware acceleration on the FPGA board, using a custom C-to-hardware tool: CflexHDL, making it possible to use a fully open-source toolchain. Interactivity is achieved by the use of a USB host capable of handling mouse, keyboards and touchscreens. Displays of multiple kinds are supported by the use of PCB adapters, including: Analog VGA, DVI protocol (compatible with HDMI monitors), LVDS for direct connection to laptop replacement displays, among other options. The controllers can be used stand-alone (like a development platform) or be controlled by other systems like Arduino or similar boards.

Firmwire full-system 5G baseband emulation — Easier testing of 5G baseband modems with FirmWire

FirmWire is an open source full-system baseband firmware emulation framework for emulating, fuzzing, debugging, and root-cause analysis of smartphone baseband firmware. This project builds upon the framework to support newer, 5G capable, smartphones. Baseband processors are used in all modern smartphones for cellular network connectivity and are a remote attack surface. As such, baseband security is of utmost importance. Baseband firmware is complex, proprietary, and lacks public scrutiny. Emulation and reverse engineering are one of the few public ways to analyze baseband processors. These efforts will provide more transparency in baseband firmware and improve the community’s ability to analyze 5G security through emulation and fuzzing. Additionally, the reverse engineering efforts could aid in developing better open source drivers in the future.

Alive2 — Translation validation for LLVM

Modern compilers, such as LLVM, perform advanced optimizations to improve performance and reduce binary size of programs. However, getting these optimizations correct is very challenging: there are many corner cases, tricky issues with undefined behavior, modular arithmetic, and so on. On the other hand, programs rely on compilers being correct. A single bug in the compiler may introduce security vulnerabilities in the compiled programs. Alive2 aims to solve this issue by verifying that LLVM is correct. It is an indispensable tool for compiler developers and for anyone that wishes to validate the compilation of their program.

Arcan-A12 Directory — Server side scripting API for Arcan's directory server

A12 is an explorative p2p protocol for fast and secure remote application interactions. Current desktop protocols are locked inside the constraints of their origins, and most of these have significant security and privacy issues. As a result, we've come to depend heavily on web frontends as the universal desktop application corset - which in return has caused a massive complication and overloading of the browser.

A12 establish a secure and interconnected network of personal compute devices, includes peer-to-peer channels and cryptography components. This project add a directory server that can be used as a trusted 3rd party rendezvous to establish such channels. It will expand the scripting API towards writing assistive 'apps' that can complement or split the workload handled on client devices; provide state synchronization and indexing/search between dynamic mesh networks created by linking directory servers together; dynamically launch and attach controlled sources.

Arcan-A12 Tools — A12 clients for different platforms and devices such as drawing tablets

The interaction patterns with our compute devices have switched from "one device - multiple users" over to "one user - multiple devices" and this new reality requires shift in how user personal data is shared and synchronised between their devices.

A12 is a network protocol designed to establish a secure and highly interconnected network of personal compute devices that has been developed as part of a larger Arcan umbrella project. The protocol includes peer-to-peer channels and cryptography components.

This follow-up project sets out to implement lightweight applications that will be capable of networking over A12 protocol to enable remote control, sensor and screen sharing, file sharing, notification sharing and enable other personal data flows. The end goal is convenience of having interconnected devices without sacrificing privacy and performance.

Automerge — Add Merkle Search Tree support to Automerge

Automerge is a CRDT library for building local-first collaboration software, allowing several users to concurrently edit a file, both in real-time and offline. It is currently optimized for working on a single document; this project aims to improve Automerge's support for synchronizing large collections of documents across multiple devices (for example, all of a user's notes in a note-taking app). The challenges here are efficiently determining which documents need to be synced, syncing multiple documents in parallel, giving users a progress indicator during large data transfers, and making the protocol efficient in terms of computation, memory, and bandwidth. Our protocol will be compatible with both client-server and peer-to-peer synchronization.

Detecting Forged-Origin BGP hijacks — Probabilistic detection of BGP hijacking

Hackers often exploit vulnerabilities in BGP, the primary inter-domain routing protocol (essentially the “glue” that connects all networks on the Internet), to hijack Internet traffic. Our project builds on our work in detecting forged-origin BGP hijacks, a specific type of BGP hijack that remains unaddressed by recent cryptographic efforts aimed at securing BGP. Our objective is to enhance the accuracy of our detection system, which relies on a probabilistic model to compensate for the lack of cryptographic tools, ensuring that no attack goes unnoticed. Additionally, we plan to share our data and improve access to our inferences by developing APIs. This will enable both network operators and the research community to benefit from our findings and apply them to improve the security of their networks.

BIDS: Binary Identification of Dependencies with Search — Identify known open source elements present in binaries

Embedded device firmware is assembled from many FOSS package dependencies. Knowing which dependencies have been used is essential for security and licence compliance. However this is a complex task for native ELF binaries built from languages such as C/C++ that do not have package managers for metadata and simpler conventions for bytecode like Java or Python. The BIDS (Binary Identification of Dependencies with Search) project will build a tool (in Python) to analyse ELF binaries and find dependencies contained and built in these binaries. The BIDS project will deliver tooling to analyse ELF binaries and extract key features and store these for indexing, tooling to index these binary features in a search engine using inverted indexing, and a query tool and library to process large binaries to query this inverted index. The latter will return results as lists of ranked FOSS packages and files found to be present in the analysed binary. The data and tools will also be packaged to allow for further integration and reuse by other FOSS tools and analysis pipelines.

Back2Source next — Better matching of binaries with source code

Sometimes, the released binaries of an open source package do not match its source code. Or the source code does not match the code in a version control repository. There are many reasons for this discrepancy, but in all cases, this is a potential serious issue as the binary cannot be trusted. Additional (or different) code in the binary could be malware or a vector for unknown software vulnerabilities, or create FOSS license compliance issues.

"Back to source" creates analysis pipelines in ScanCode.io to systematically map and cross-reference the binaries of a FOSS package to its source code and source repository and report discrepancies. We call this the deployment to development analysis (d2d) to map deployed code (binaries) to the development code (the sources) and we enable applying this "trust but verify" approach to all the binaries.

Tracing and rebuilding packages — Improved metadata/provenance for build artifacts

For many end users the smallest unit of software is the "package": a collection of programs and configuration files bundled in a single file, typically shipped as a single archive. Examples are "util-linux", "glibc", "bash", "ffmpeg" and so on.

Open source distributions install packages using their package management systems. The package management system writes the contents of a package to disk when the package is installed or updated and removes the contents if the package is removed. The packages themselves contain metadata maintained by the distribution maintainers. This information includes the name of the package, project URL, description, dependency information and license information, etc.

This granularity can be too coarse. For example, the license information is aggregated at the package level. If there are separate files that are under different licenses, then this will not always be clear from the license information at the package level.

This project will make it more easy to understand by looking at what goes into each individual binary in a package, and assign metadata to the individual binaries instead of to a package. It will do so by tracing the build of a package and recording which files are actually used. By building packages in a minimal (container) environment, capturing the build trace, processing the build trace to see exactly what goes into which binary it becomes much easier to zoom in and answer specific questions such as "what license does this binary have" or "which binaries use vulnerable file X" and combining it with efforts like VulnerableCode and PurlDB.

CAKE-MAINT — Improve network queue management algorithms on Linux

With the wider and wider adoption of the fq_codel (RFC8290) and cake codebases in shipping products, many issues in the field have been discovered, and features to address them proposed but not mainlined into Linux (or the BSDs). This project intends to tighten up the corner cases, fix up multiple observed problems, and add some needed new features if possible, as well as take a stab at addressing the biggest observed problem in the field for cake - not scaling shaping well to ever more popular multi-core routers.

In addition the project will work on a new release of babeld, the reference implementation of RFC 8966 (Babel Routing Protocol) and on standardisation of Sroam, a protocol for WiFi roaming.

CRAVEX 2 Code Reachability — Do vulnerable dependencies actually impacts security or not?

CRAVEX makes it easier for any organization to efficiently comply with the emerging CRA. CRAVEX collects, tracks, and triages FOSS package vulnerabilities, determines their exploitability in a portfolio of software products and projects, and provides reporting with SBOMs and VEX statements to share with stakeholders.

CRAVEX 2 enables CRAVEX users to triage vulnerabilities faster and more efficiently with automation and more accurate vulnerability data. An integrated, rule-based system automatically filters or reranks the vulnerabilities in the context of the managed application, system or device. This will integrate the emerging SSVC scoring for decision trees-driven automation. Vulnerable code "reachability" determines if the code impacted by a CVE is present, used, and exploitable. It will integrate and extend the features of NGI0-funded and FOSS projects, such as BANG.

With increased automation and more accurate data, CRAVEX 2 further facilitates CRAVEX users' ability to efficiently manage vulnerabilities towards CRA compliance.

Cross-root ARIA — Standardisation for Accessibility when using Shadow DOM

ARIA is a technology used by developers to add accessibility attributes to web-based user interfaces. Web Components are a set of tools which allow developers to create components which can be used in a framework-independent way across different websites. Due to the way Web Components provide encapsulation, using Shadow DOM, some parts of ARIA have become incompatible with Web Components. This project will contribute to ongoing efforts to provide web developers with mechanisms to make these technologies work together. Our goal is to contribute to the relevant specifications, as well as implementing and shipping the proposed solution in one additional browser.

Open source ESP32 802.11 MAC — Open source wifi drivers for ESP32

The ESP32 is a low-cost microcontroller with Wi-Fi connectivity. Currently, the Wi-Fi MAC layer of the ESP32 is closed-source. This project aims to change that: by reverse engineering the hardware registers and software, we can build a networking stack that is open-source up to the hardware, instead of having to use the proprietary MAC layer. This will improve security auditability, open up the possibility for features not supported in the proprietary implementation (for example, standards-compliant mesh networking), improve interoperability and make research into Wi-Fi networks with lots of nodes more affordable.

Encaya — TLS interop with alternative/decentralised CA mechanisms

Public certificate authorities as used by the TLS ecosystem play a critical role, but the fact that there are many such authorities forms a security liability. DANE (DNS-Based Authentication of Named Entities) provides a complementary mechanism that provides an additional check on top of the public CA's through DNS; it is yet to see meaningful adoption by major TLS implementations.

Encaya is a compatibility layer that provides DANE-like functionality in TLS implementations that don't support DANE. It is used in production by Namecoin, an alternative decentralized naming system. By only replacing the root CA list rather than the entire TLS stack, Encaya achieves considerably smaller attack surface than other similar compatibility layers. This grant covers efforts to improve Encaya's scalability, standardize its behavior, and extend its usage beyond Namecoin.

Ethersync — Real-time co-editing of local text files

Ethersync aims to enable real-time collaborative editing of local text files. Similar to Etherpads, it facilitates multiple users to work on content simultaneously, enabling applications such as shared notes or pair programming. However, following a "local-first" approach, all files reside on the users' computers, allowing them to use their familiar editors and workflows, and to retain user control. This design enables a kind of collaboration that is simple and direct, stable and flexible, and preserves privacy. Ethersync will be a supplement to tools that track larger changes on text files, like Git, and can be used in combination with it. The project will leverage CRDTs, and consists of a server component, a cross-platform local synchronization daemon, and editor plugins.

Exter — Proxy-based external browser extensions

Exter is a web based plugin platform which allows addons to alter websites behavior/style/functionality. Instead of trusting the browsers' plugin ecosystem, let's modify the websites before browsers receive them! The goal of this project is to provide a stable and free website-extension-platform to allow future proof and flexible addon development.

As a web application, Exter opens URLs, rewrites the static content and injects client scripts to wrap default javascript functions, applies addons, then sends the sanitized/modified website to the browser. This way we have the ability to write plugins that can intercept/modify not only HTTP requests, but even client side functionalities, such as sanitizing 3rd party content or appending new DOM elements to the website or altering cookie handling from javascript and much more.

FOSS Warn — Aggregate source of emergency alerts

The FOSS Public Alert Server lets clients receive Push Notification (via UnifiedPush) about official emergency alerts worldwide. Besides infrastructure like sirens, radio, and Cell-Broadcast, CAP (Common Alerting Protocol) alerts are another way of alerting the public. CAP alerts are used for a wide variety of emergencies. From alerts about extreme weather to alerts about contaminated drinking water to pandemics. Our server bundles over 280 official CAP alert publishers worldwide and can easily extend to more sources. This project aims to bundle the underlying alerting infrastructure into a single trustworthy source of information, not to replace it.

Having a shared global public source of information reduces the user's dependency on local emergency apps - which are often only available for the two largest mobile platforms. Furthermore such a converged effort makes it much simpler to develop clients for devices other than cell phones (like desktop PCs or smart speakers). Thirdly it can make traveling safer. Finding and installing the right local emergency apps to receive emergency alerts when traveling is quite the hurdle. With our solution, it would suffice to install one app for the world. One such app is FOSS Warn, an Android app that for now receives alerts for Germany and Switzerland. Within this project, FOSS Warn will be extended to work worldwide with the new server infrastructure.

Feather UI — Declarative cross-platform UI toolkit

Feather is a universal UI library that applies user inputs to application state, and maps application state to an interactive visualization using a custom graphics rendering language capable of compiling to arbitrary GPU code or vectorized CPU code. By building on top of a well-typed graphics abstraction, it is possible to make custom shaders "write once, run anywhere" with confidence and no overhead. This allows the creation of UI Fragments, which no longer need to be built on top of a library of UI widget elements, allowing the creation of arbitrarily complex UI elements that are no longer bound to traditional widget designs. This level of abstraction allows targeting anything from embedded devices to webpages, or even mixed-reality devices.

Fediverse Test Framework — Test bench for ActivityPub implementations

The Fediverse consists of individual servers, possibly running different software, that talk to each other. One of the challenges in developing for the Fediverse is to stay interoperable with all the different deployed software. As the message format standard, ActivityStreams, is extensible through JSON-LD, judging how a message is parsed, can be a hard task.

By using ideas from automated testing, we provide an application that determines a baseline how messages are processed and rendered. The process being simply: run end to end tests and record their result. From the test results a webpage is generated that provides developers the information how a message is rendered in different applications. We aim to make the framework extensible so new applications can be included.

Fediverse Test Suite — Interoperability effort for W3C ActivityPub

The Fediverse is a global, standards-based, decentralized social network accessible to all and not subject to algorithmic manipulation or platform surveillance. While best known for Mastodon, an open-source alternative to X/Twitter, it already successfully connects dozens of independently developed software applications running on tens of thousands of independently operated servers and implementing feature sets that go far beyond traditional social networking.

To enable even more innovative developers to successfully connect their applications to the Fediverse, and their users to successfully interoperate with users using different software, it needs to become much simpler and cost-effective for developers to 1) know that they have implemented the relevant standards (notably ActivityPub) correctly, that their implementation is not regressing and that 2) their software indeed delivers the experience users expect from interoperability with other software developed independently by other developers.

This project brings together a group of fediverse developers to set up an automated test framework and initial test cases in an open-source project that will systematically test standards conformance, ensure meeting user expectations for interoperability of Fediverse apps, and enable a new wave of innovation based on more trustworthy infrastructure.

Flashkeeper — Write Protection on SOIC-8 flash chips without soldering

Firmware security projects such as Heads assume the firmware itself to be protected against tampering. Outside of proprietary solutions Boot Guard, partial write protection (WP) of the SPI flash chip (recently implemented by 3mdeb) is one solution. However, WP requires grounding the chip's WP pin, something that currently requires users to solder to the chip. As many users find this difficult, this has limited "retrofit" adoption of WP.

This project is developing Flashkeeper, a device that can be permanently installed on a common SOIC-8 flash chip. It attaches to the chip with a peel-and-stick layer and spring-loaded contacts or low-profile solder-down flex cable, interfacing with the SPI flash pins for easy write protection and external reprogramming (unbricking). For users concerned with physical attacks on their systems, for whom easy access to SPI flash pins may be seen as a risk, a variant including a microcontroller (MCU) is also being developed, allowing authenticated external reprogramming and WP control, and independently verifying the SPI flash image against a user-controlled signature each boot.

ForgeFed Frontend — Improved UI for federated version controlrepositories

Software developers often use websites called forges, where they collaborate on software projects. But these forge platforms are centralized, leading to the community flocking into big privately- controlled forges. The ForgeFed project is creating a protocol specification and a reference implementation for forge communication, allowing forge websites to form a decentralized network, putting the power and freedom of choice back in the hands of the community.

Namespace-specified imports in GHC — Fine-grained namespace control in Haskell

Haskell is a purely functional programming language with a free and open-source compiler (GHC), as well as a mature ecosystem of open-source libraries for server-side programming (warp, wai, servant, scotty, etc), client-side programming (http-client), and blog generation (hakyll). By making use of Haskell's features, especially its support for concurrent and parallel programming, it is possible to develop efficient, secure and scalable web servers.

"Namespace-specified imports" is a proposed feature for the Haskell programming language that further enhances its capabilities. By implementing "Namespace-specified imports" in the Glasgow Haskell Compiler, we will enable Haskell programmers to exercise fine-grained control over the namespaces of imported and exported entities. This is important when combining the use of existing libraries with the use of type-level programming features (techniques to ensure software correctness).

This project should result in a complete implementation of this feature and its inclusion in the next compiler release.

GNU Mes interpreter speedup effort — Increase performance of full source bootstrap

GNU Mes is a Scheme interpreter (mes), C compiler (mescc) and a minimal C standard library (meslibc) for bootstrapping the GNU System. The Scheme interpreter is written in a few thousands lines of simple C, and the C compiler is written in Scheme, and these are mutually-hosted. GNU Mes has a key role in the Full Source Bootstrap chain as it is the first fully featured C compiler that also ships a C standard library.

This project aims to improve the performance of GNU Mes' scheme interpreter, rewriting it as a bytecode interpreter, while keeping it as simple and readable as it is. This would enable faster execution of the Mes C Compiler (mescc) for faster build times, making the bootstrapping chain more accessible, specially in small single-board computers where memory access is more expensive. This speedup could also lead to a reduction of steps in the bootstrapping chain, making it simpler and easier to maintain.

GNUnet on Android — Port GNUnet protocol stack to Android mobile OS

This project is about making GNUnet, a network protocol stack for developing secure, distributed and privacy-preserving applications, available on Android. To achieve this, we are developing an Android application that runs the basic GNUnet services and make them available to other applications that want to use these services. As a blueprint for an application that uses GNUnet services, we will port the GTK-based GUI for the GNUnet's messenger service to Android. To get GNUnet running on Android, we need to make sure that GNUnet works behind NAT boxes in the mobile environment, and make changes to the GNUnet architecture so that it runs as a monolithic single-threaded app. Additionally, we have to take care of the resource consumption on mobile devices. Of course, tests and benchmarks need to be written and integrated into a new CI/CD worker that builds and verifies GNUnet on Android.

GPGPU Playground — A virtual GPU to learn GPU programming

GPUs are an extremely effective and widely deployed vector co-processor, and yet those interested in adapting their capabilities are faced with a very high barrier to entry. Tools like OpenCL, CUDA, and WebGL all require a broad background to get started solving even simple problems, and mistakes in larger programs can be nearly impossible to identify without an even deeper level of experience. This project takes advantage of WebAssembly and Vulkan's SPIR-V format to deliver a safe, on-demand toolkit for exploring the potential of GPUs, focused on applications outside the bounds of traditional graphics acceleration.

Guix-Daemon — Transition to a Guile implementation of the guix-daemon

GNU Guix is a transactional package manager and a distribution of the GNU system that respects user freedom. A key component in Guix is the guix-daemon, currently implemented in C++. Much of the power and flexibility of Guix comes from all of the package definitions and surrounding tooling being implemented in GNU Guile, however this doesn't extend to the guix-daemon. This difference has been a limiting factor in making changes and improvements to the way the guix-daemon works and is interacted with. The expected outcome of this project is to have a Guile implementation of the guix-daemon, and to transition to this being the default guix-daemon used. This will improve the maintainability and portability of the guix-daemon and Guix overall, as well as unlocking future improvements to the guix-daemon and connected tools.

Hyper Hyper Space Sync Engine and adapters — Secure P2P data synchronisation

The way authority is coded into software platforms impacts the health of the communities they serve. The goal of this project is to provide an information sync engine that can provide an application back-end with as little authority delegation as possible, thus enabling applications that are truly user-controlled.

By using a formulation based on monotonicity, Hyper Hyper Space is able to simulate a transactional engine over a cryptographically secure event log. This yields a versatile data model, that is usable in a coordination-free setting and in the presence of Byzantine faults.

This modelling flexibility can be leveraged by using bi-directional adapters, that are able to ingest and export synchronized data into a variety of local storage systems, including relational databases, document stores, and files. Application builders can choose the storage system that better suits their use-case, and rely on an adapter to synchronize its contents. This should lower the barriers of entry for creating p2p applications, and hopefully significantly boosts quality while reducing complexity.

Hockeypuck — Next generation OpenPGP keyserver

Cryptography is often said to be a method of converting security problems into key management problems. In OpenPGP, the reliable distribution of public keys has traditionally been done using public keyservers. While there are alternative methods of public key distribution, keyservers still perform a key role in the OpenPGP ecosystem.

Hockeypuck is a modern synchronising OpenPGP keyserver application written in Go and licensed under the AGPL. It powers the OpenPGP synchronising keyserver network, which is a fully decentralised caching database run collaboratively by dozens of independent operators, but can also be deployed on a private or individual basis. Hockeypuck is currently being updated to support RFC9580, the latest iteration of the OpenPGP specification, and the upcoming HKPv1 keyserver API specification.

Holo Routing — A novel routing stack in Rust, including IS-IS routing

Holo is a suite of routing protocols designed to address the needs of modern networks. Holo was started in response to the increasing trend in the networking field towards automation, where network devices are expected to be managed programatically using a variety of standard interfaces. Written in Rust, a memory-safe language, Holo prioritizes reliability, ease of maintenance, and security.

This project aims to extend Holo by incorporating support for the IS-IS protocol, one of the most widely used interior routing protocols. The IS-IS implementation will encompass both IPv4 and IPv6 support, cryptographic authentication, and extensions for traffic engineering. Rigorous testing against multiple vendors and comprehensive conformance tests will ensure the interoperability and robustness of the implementation.

IPDL II — A new process logic aimed at formal proofs for cryptographic algorithm

Our project IPDL aims to increase the trustworthiness of large cryptographic systems by designing and implementing a natural and principled way of thinking about them. IPDL, short for Interactive Probabilistic Dependency Logic, is a process calculus and software implementation for formally verifying message-passing cryptographic protocols. Our goal is to use IPDL to develop cryptographic foundations that are both composable and concurrent. Concurrency means that our model of computation natively allows processes to run at the same time; composability allows us to prove the system secure by verifying the security of its subparts. In this setting, formal proofs closely resemble the thinking of a cryptographer.

IPv6-monostack - upstream Linux SIIT/NAT64 — Commoditizing NAT64 and IP/ICMP translation to accelerate IPv6 deployment

NAT64/SIIT technology is critical in enabling networks to transition away from the legacy internet protocol IPv4, yet this network function is currently expensive and hard to deploy, seriously hampering adoption. We believe we can remedy this situation by getting this translation technology accepted into the upstream Linux kernel thus paving the way to rapid and widespread adoption, accelerating IPv6 adoption overall.

ISCC-CORE typescript implementation library — Decentralised content identifiers through ISO 24138.

The goal of this project is to implement core functions of the new ISCC standard ISO 24138:2024 (“International Standard Content Code”) in Typescript, resulting in a library will be useful for the javascript ecosystem and developers to use and work with this new standard in their project.

ISCC is a similarity preserving fingerprint and identifier for digital media assets. ISCCs are generated algorithmically from digital content, just like cryptographic hashes. However, instead of using a single cryptographic hash function to identify data only, the ISCC uses various algorithms to create a composite identifier that exhibits similarity-preserving properties (soft hash). This supports content deduplication, database synchronization, indexing, integrity verification, timestamping, versioning, data provenance, similarity clustering, anomaly detection, usage tracking, allocation of royalties, fact-checking and other use-cases.

Optimized Image Codecs — More efficient image handling for embedded systems

The Optimized Image Codecs project aims to bring portable, efficient image and video codecs to all platforms. It is primarily focused on enabling them on devices that previously were assumed to be incapable of using standard compressed images or video due to their limited memory and speed. The efficiency of the code also means that energy usage is reduced on systems large and small. This code represents state of the art efficiency combined with a careful design to minimize the memory requirements. This enables their use on the widest possible set of devices. This project started with the release of a JPEG decoder and now consists of mature JPEG, PNG, GIF and TIFF G4 codecs used by thousands of developers in projects large and small. Within the scope of this project, the aim is to release software MPEG-1 and H.263 video decoders which will run well on low cost microcontrollers. This should dramatically improve the efficiency of products which had to settle for MJPEG (Motion-JPEG) as a substitute for a true video codec.

Micro25519 — Lightweight Elliptic Curve Cryptography for microcontrollers

This project is building an open-source software library for modern Elliptic Curve Cryptography (ECC). To achieve this, the project aims for a unique trade-off between three different (and partly conflicting) goals that is currently not offered by any of the existing ECC libraries for small 8/16/32-bit microcontrollers. The first goal is efficiency, which includes not only fast execution times, but also small code size and low RAM usage. Equally important as efficiency is the second goal, namely security, and this includes not only the absence of subtle bugs that could leak secret information, but also robustness against timing-based side-channel attacks. The third goal is usability, which is achieved by a simple and intuitive API, an easily readable and well-commented source code, and a rich documentation with examples for common use cases.

Micro25519 will come with highly-optimized Assembly functions for the low-level field-arithmetic for 8-bit AVR, 16-bit MSP430, as well as 32-bit ARM Cortex-M3 and RISC-V microcontrollers. The higher-level functions are written in C and shared among the different platforms to minimize the code base and reduce complexity.

Irdest IP Traffic Proxy — Route existing IP-network traffic through an Irdest network

An Irdest network allows users to easily create locally focused mesh networks amongst their communities and friend circles. To allow applications not written for this mesh network (using IP traffic routing) to route traffic through the Irdest network a proxy is required. This proxy is responsible for managing routes on entry and exit nodes, announcing routes, and allowing users control over which exit nodes they want to use for different target IP addresses. The goal of this proxy is to provide a better out-of-the box experience for new users, and expanding the scope of usable scenarios.

AppBundler — Package (graphical) Julia apps for all platforms

While Julia provides excellent support for GUI frameworks across all major desktop operating systems, deploying these applications traditionally requires users to install Julia, instantiate projects, and run them from the command line. AppBundler addresses this challenge by creating self-contained, native installers for Julia GUI applications regardless of framework. It employs a flexible recipe system with sensible defaults, allowing developers to easily configure resulting bundles. This project will integrate open-source bundling tools for macOS and Windows to replace proprietary SDKs, enabling distribution as binary dependencies without cumbersome host setup and facilitating cross-platform deployment from Linux hosts. AppBundler will support various Julia compilation methods, including pkgimages, sysimages, and Julia 1.12+ static compilation features, while developing Flatpak integration and addressing sandboxing to ensure applications run securely without compromising user systems.

KDE Plasma Wayland — Accessibility and advanced graphics input support for KDE Plasma Wayland

Plasma is the desktop provided by the KDE project, one of the largest and most successful open source initiatives in the world. Wayland is the successor of X11 for Unix desktops and the future for many reasons, including security and privacy. However there are some user groups that currently do not have their requirements satisfied. Some people have motor impairments of their arms/hands (such as restricted movement, tremors, or missing fingers) that make it hard or impossible to operate a traditional computer keyboard. Operating systems provide a number of options like sticky keys, slow keys, or bounce keys to accommodate for such disabilities. Another pain point is configuration of graphics tablet input devices. This includes things like mapping the tablet area to an output area, binding tablet/stylus buttons to actions, or configuring pen pressure curves. This project will implement support for these special user groups in KDE Plasma on Wayland.

Kami — Choreography programming language integrated with the Rust ecosystem

Kami is a new programming language, based on the Rust ecosystem, designed from the ground up for correct-by-construction distributed systems. In its core it is pure and functional, thus ideal for building complex concurrent systems. It takes cues from multiparty session types and choreographic programming language research: The behaviour of all roles in a distributed application can be implemented at once from a global point of view. This high-level description is compiled to rust code for all participating roles, with the guarantee that the system will be deadlock-free. Developers can seamlessly drop down to using rust, and all of its ecosystem, for writing local code, while using Kami for composing the local computations into a coherent distributed system. In this project we implement the type-checker, compiler and other developer tools for Kami, to provide for a similarly friendly developer experience as Rust.

Librecast Overlay Multicast — Privacy-preserving, energy efficient data replication and verification

The original design goals of the Internet do not match today's privacy and security needs, and this is evident in the technologies in use today.

The Librecast project contributes to decentralizing the Internet by enabling multicast. Multicast is an important network capability for a secure, decentralized and private by default Next Generation Internet. Multicast is networking with consent. Unfortunately, today's infrastructure does not fully support end to end multicast. In order to reap the benefits of multicast in the applications we build now, we need a transitional mechanism which enables overlay multicast via peer to peer tunnels so that multicast applications - using the Librecast libraries - can work everywhere, regardless of underlying network support.

The Librecast project is building the transitional protocols and software required to extend the reach of multicast and enable easy deployment by software developers, to make end to end encrypted multicast a reality.

LANShield — Constrain local network access for mobile devices

LANShield is a tool that will give users control over which apps and programs are allowed to access devices in the local network. This is done to defend against malicious apps that may try to scan the user's local network and subsequently leak sensitive information. For instance, when an app tries to access the local network for the first time, the user is asked whether this app should be allowed to access local devices. The project will also investigate models and protocols to safely enable an app to communicate with local devices, with the idea that apps can use this protocol to access local devices without requiring explicit user permission. The project will also investigate how to integrate this defence into Android.

MEGA65 Phone Modular MVP — OSHW mobile device with form-factor of hand-held game consoles

The previous MEGAphone project laid the groundwork for creating personal communications devices that are secure through simplicity. This project extends that work by making the hardware modular, at some cost of minimum size, so that it becomes much more feasible for small communities to produce and maintain their own units, even in the face of supply chain challenges and other contributors to the "digital winter", i.e., the situation where open innovation becomes more difficult due to number of factors. This will also make it easier to include diverse resilient communications options, whether RF, optical or acoustic, so that peer-to-peer communications networks can be sustained even in environments that are hostile to freedom of communications. For this reason energy sovereignty will also be part of the design, so that even if all civil infrastructure is denied, that basic communications and computing functions can be sustained, with a single device whose security can be much more easily reasoned about.

Improving the deployability of Multipath TCP — Improve MPTCP support in the Linux kernel

Multipath TCP (MPTCP) is a standardised technology extending TCP and invented in Europe. TCP is one of the key protocols of the TCP/IP protocol stack, designed in the 1970s when hosts were attached to the network through a single cable. Today's hosts have several network interfaces, but TCP only uses one of them for a given connection. Multipath TCP solves this problem by enabling TCP connections to exchange packets over different network interfaces. With the current version of MPTCP in the Linux kernel, most of the features listed in the RFC8684 are implemented. Basic use-cases are supported but still it doesn't mean the solution is covering all needs and is easy enough to use. In short, MPTCP works well in some controlled environments but not as good in too heterogeneous ones like it is common to see on the Internet. Also its configuration is sometimes seen as difficult and/or confusing for the moment. Some work is then still needed to cover more use-cases plus to improve the usability and performances in order to have Multipath TCP adopted by a broader audience.

With the current version of MPTCP in the Linux kernel, most of the features listed in the RFC8684 are implemented. Basic use-cases are supported but still it doesn't mean the solution is covering all needs and is easy enough to use. In short, MPTCP works well in controlled environments but there is room for improvement in heterogeneous ones. Some work is then still needed to cover more use-cases plus to improve the usability and performances in order to have Multipath TCP adopted by a broader audience.

MailBox renewal — Performance upgrade of MailBox mail modules

Email is still the workhorse of the internet, and behind the screens some of the heavy lifting is by applications like the Mailbox modules. Under the hood, this software is processing billions of emails every day at some of the largest players in the industry.

The project will deliver a major update of the code after two decades. This is not only long overdue, but actually offers interesting opportunities to take into account new email related RFCs, investigate new possibilities for code optimisation as well as tackling new threats like SMTP smuggling.

As a bonus, the project will work on a standalone tool to be able to once more properly forward emails in the SPF/DMARC era - a very welcome capability, the lack of which is currently causing a lot of headache and lost email for users.

Mapterhorn — Open terrain tile sets and data catalog

Mapterhorn is an open-source alternative to proprietary terrain data platforms that addresses the fragmentation of global high-resolution terrain data. While many European countries like Austria and the Netherlands have released open terrain datasets, users currently rely predominantly on proprietary intermediaries such as Google Maps or Esri to consume these. This is due to inconsistencies in formats, projections, licenses, and access methods. Mapterhorn solves this through three components: a global low-resolution terrain tileset based on ESA's Copernicus model, regional high-resolution tilesets from national LIDAR surveys, and a comprehensive data catalog using the open STAC specification. By distributing terrain tiles in Web Mercator projection in standard formats such as GeoTiff and PMTiles, Mapterhorn will enhance disaster response capabilities, improve solar energy planning, boost tourism promotion, and enable numerous other applications across the public sector in Europe and beyond.

postmarketOS/phosh-mobile-settings integration — Consolidate functionality of FOSS mobile settings applications

Currently, there is no easy way for applications to install settings that then show up in the system's settings app on desktop Linux systems. As part of bringing desktop Linux to mobile phones in postmarketOS, we have created a "tweaks" app for phone-specific configuration options. With this project, the options in this tweaks app will be converted to a format described by a specification which settings apps then can implement. This in turn is part of a broader effort to make desktop Linux suitable for running on mobile phones as a means to create an operating system for phones without excessive user tracking or built-in ads, with a focus on the user instead of money.

Mobilizon UX — Share events on the fediverse

Mobilizon enables the creation of community venues for organising and promoting local and topical events, activities, and groups. These instances can share information using the ActivityPub protocol, allowing users to publish their events on one Mobilizon server and propagate these elsewhere. Mobilizon is designed to be user-friendly and empowering.

In order to reach a wider audience with Mobilizon, we need to make sure we serve the needs of users well - whether they are instance administrators, event organisers, or end users. We will conduct workshops to study how each of these interacts with Mobilizon and understand their expectations, so that we can develop Mobilizon accordingly. Additionally, we will test, document and improve interoperability with other Mobilizon instances, other fediverse applications, and other websites in general. This can be achieved through plugins, APIs, and aligning on standard formats such as Ical. Ultimately, communicating about local activities will become more efficient and finding local activities easier.

Mosaic Simulation — EDA tool for analog chip design

Today, the chip design industry is deeply proprietary with NDAs at every level, which means it is not possible to share design files at all. This in turn stifles learning, innovation and transparency in chip design. In order to create a chip design industry that can be trusted with our digital lives, and which is accessible to educational institutions and small business, it is essential to develop powerful open source tools for chip design. Anyone should be able to use these tools, allowing for unhindered collaboration.

Mosaic is a tool that attacks the first design phase of an analog chip, or analog peripherals for a digital one: design and simulation of the schematic. In this follow-up grant the team will focus on simplification, distribution, and polish - making Mosaic easier to install and use as well as maintain.

Movim — Add end-to-end encrypted videocalls to Movim XMPP

Movim is a web-based social and chat platform that acts as a frontend for the XMPP network. The goal of this project is to modernize and extend the long-existing audio and video conferencing features in three major steps. First, the existing UI will be completely refactored and redesigned to better integrate the conferencing features into the existing pages and flows. Secondly, Movim will support one-to-many call features and offer full compatibility with other XMPP clients building upon the step-one features but without relying on a central server to handle the media streams. And finally, to handle conference calls with a large number of participants, Movim will standardize and integrate SFU (Selective Forwarding Unit) support that will then lift the streams network bottlenecks offering a complete and scalable experience to its users. With those three steps fulfilled Movim will then be able to greatly simplify fully standard XMPP audio and video conferencing calls on the web.

Mox management and automation — Automated email server management and administration

Mox is a modern email server implementation that makes it easy for people and organizations to run their own mail server, allowing them to stay in control of their own email communication, and keeping email decentralized. While high-quality open source mail server software components exist, their code bases are growing old, and getting a working setup involves configuring at least half a dozen of them to work together. That complexity has turned people to a few (centralized) email providers. Within this grant the team will add a number of missing key features such as server-side email filtering (Sieve) and encrypted storage, among others.

Collation + i18n support in musl libc — Complete POSIX internationalised functions in musl libc

musl libc is a lean C standard library implementation for Linux. It strongly focuses on correctness, compliance with standards, and reduced footprint, both in terms of binary size and memory usage. Its initial release dates to 2011, making it a considerably modern implementation compared to alternatives like glibc. As default in e.g. Alpine Linux (which is widely used in containers but also is the basis for end user facing efforts like postmarketOS) it can be found in many unexpected places.

This project will implement two features still missing: collation and internationalization support. The first one allows set ordering based on locales, and follows a certain set of established rules and standards. The second one provides basic functionality in the language of choice for the user like dates, times, numbers, and monetary symbols. Contributors from the postmarketOS community will validate the work, to make sure that everything actually works out as intended.

NodeBB — ActivityPub support and accessibility improvements for forum software

NodeBB is a Node.js based community forum software utilizes web sockets for instant interactions and real-time notifications. NodeBB benefits from modern features like real-time streaming discussions, mobile responsiveness, and rich RESTful read/write APIs, while staying true to the original bulletin board/forum format — categorical hierarchies, local user accounts, and asynchronous messaging.

In this project, the team will be working on bringing ActivityPub integration to NodeBB, in order to allow forums to become truly interconnected with other ActivityPub-enabled applications throughout the wider Fediverse (of course including other NodeBB forums). The absolute hardest part of starting a community — forum or otherwise — is gaining a critical mass of adoption in order to sustain interest and content. What if we could bypass this hurdle altogether?

Nova JavaScript engine — Independent JavaScript engine written in Rust

Nova is a JavaScript engine exploring a different, data-oriented design inspired JavaScript engine design. This design allows greatly reduced memory usage, optimal data cache locality for algorithms on happy paths, memory safety by construction, and various other technical optimisations that together form a compelling and interesting whole. The design involves tradeoffs, paying extra indirection for its gains, and the implementation treads mostly unfamiliar territory: the technical choices are nothing new, but they have not seen wide usage in production JavaScript engines to date. If the upsides overshadow the downsides, as they seem to do, the result will be a JavaScript engine that reduces memory usage by 30 to 50 percentage points, while improving performance under real-world loads.

O-ESD — Open-hardware for ElectroStatic Discharge testing

The goals of the Open-hardware for ElectroStatic Discharge testing (O-ESD) is to design, produce and verify an open-hardware and accompanying open-software for a device for electrostatic discharge testing. Electrostatic discharge is a phenomenon that occurs daily between humans and electronics and can irreversibly damage the electronics. All consumer electronics sold in EU, including all internet hardware, must satisfy Electromagnetic Compatibility (EMC) Directive. One of the most hardest tests within EMC directive deals with electrostatic discharge as defined by IEC/EN 61000-4-2 standard. Standardized tests are typically done with special equipment in accredited EMC laboratories and are costly. The O-ESD tester will minimize the costs of pre-compliance testing and make it publicly available.

OCaml direct style transition — Helping with the transition of OCaml programs from Lwt to Eio

OCaml traditionally uses monadic style for concurrent programming, offering advantages like reduced data races and efficiency but requiring all code to be written in this style and leading to frequent allocations. OCaml 5 is one of the first languages to implement algebraic effects, enabling direct-style concurrency with multiple stacks, addressing these drawbacks. However, the transition to effects-based concurrency can lead to incompatibility between libraries written in different styles, putting the whole OCaml ecosystem at risk. This project aims to mitigate these risks by developing tools to automatically rewrite code and identify potential issues during the transition from monadic to direct-style concurrency, specifically focusing on the complex case of the Ocsigen Web framework.

OPERA-DSP — Open hardware FMCW Radar signal processing in FPGA

Frequency Modulated Continuous Wave (FMCW) radar is essential for applications such as autonomous vehicles, industrial automation, environmental monitoring, and security, enabling high-resolution object detection and speed estimation. However, to fully leverage FMCW radar data, digital signal processing (DSP) techniques must be applied in real time to extract meaningful information. The OPERA-DSP project aims to develop an open-source FMCW radar DSP hardware library, making radar signal processing more accessible to researchers and developers. It will provide essential IP cores, including windowing functions, Fast Fourier Transform (FFT), magnitude computation, and Constant False Alarm Rate (CFAR) detection. To simplify adoption, OPERA-DSP will integrate these DSP libraries with a RISC-V core and develop an FPGA-based design, complemented by scripts for automated bitstream generation.

owi — Symbolic evaluator and fuzzing of WASM software

WebAssembly (Wasm) is a post-JavaScript code format for the web, enabling efficient computing, with built-in sandboxed execution. Its usage is expanding: it is now used in online services, in embedded systems and to create portable binaries.

Owi is a toolkit tailored for Wasm. In particular it can perform efficient symbolic program execution. That is to say, for a given program, it is able to find input values leading to a crash. Many languages are compiling to Wasm, e.g. C/C++/Rust. Owi can thus be used as a bug-finding tool working on any of these languages. We're currently improving the usability of the tool as a part of the testing workflow for developers, the first step of this work is to provide an interface making Owi a drop-in replacement for AFL.

Open Cloud Mesh — Improved specs and test suite for Open Cloud Mesh protocol

The Open Cloud Mesh protocol, at its core, defines a wonderfully simple JSON payload to notify another server when a user wants to share a folder or file with a user on that server. It is implemented by some major Enterprise File Sync and Share (EFSS) vendors, and used in production by several serious organisations - including major National Research and Education Networks (NRENs). But its specification and test suite are still lacking in substance and quality. In this project we will improve the specification text, flesh it out to a more strictly defined (RFC-style) text that addresses all aspects and considerations of the protocol. In addition we improve the test suite so that it can be run in Continuous Integration (CI) instead of requiring frequent manual intervention, and clarify any incompatibilities we find between implementations.

OpenEMSH — Automatic mesher for FDTD simulation

OpenEMS is arguably the only free and open source FDTD solver out there that is usable out of the box for RF (Radio Frequency electromagnetics) design. Its main competitive disadvantage is that FDTD requires simulated models to be meshed according to specific rules, yet it does not provide an automatic mesher to create such meshes. Some facilities already do exist but meshing by hand is time-consuming and error-prone - enough to stand in the way of broader adoption. OpenEMSH aims to be a mesher for OpenEMS that makes it as simple to use as any proprietary solution.

OpenHarbors — Dynamic Tunneling of WPA over IP/L2TP

OpenHarbors wants to establish a novel approach for secure communication over an untrusted Wifi network - and beyond: Dynamic tunneling of WPA over IP/L2TP. Why? Because current, secure solutions are not satisfactory: They are either hard to set up, require extra software in advance or are not applicable on an open wireless community mesh network like Freifunk.

OpenHarbors will utilize and implement WPA Enterprise with an extra twist: Instead of providing an encryption channel only between your mobile device and the direct WLAN access point you will be able to securely dial-out at any location on the internet you trust and choose and are granted access to. Without the hassle of installing and setting up an extra VPN software on your phone. Without the need of a trusted WLAN access point operator model or closed source firmware, in contrast to current approaches with Passpoint/Hotspot 2.0/eduroam/WBA OpenRoaming and similar - which all are conceptually not applicable on open wireless community mesh networks.

Open Web Calendar Stack — Aggregate public and private web calendars

The Open Web Calendar stack is an open-source set of Python libraries and programs which read and write calendars based on the iCalendar standard. The Open Web Calendar displays a highly configurable website that can be embedded to show a calendar. Currently, ICS URLs are supported and a goal is to also support CalDAV.

Amongst the used libraries is the popular icalendar library to parse and write iCalendar (RFC5545) information. This cornerstone of Python's ecosystem requires some work to be up-to-date with common practice such as updating the timezone implementation. The updates to the icalendar library will be tested and also pushed up the stack to the Open Web Calendar.

The recurrence calculation of events is done by the python-recurring-ical-events library. Changes to icalendar will be tested against this library to find compatibility issues. As the iCalendar standard has been updated, recurrence calculation is affected, too. These updates need to be evaluated and possibly implemented for both icalendar and the recurrence calculation.

By implementing changes at the base, the whole stack is improved. We can use the Open Web Calendar project to make sure that possible transitions and updates are mapped out and communicated to other projects in the ecosystem. Improving a FOSS solution thus spreads the accessibility of iCalendar.

Open Web Calendar Stack II — Recurring events and calendar merging

The Open Web Calendar creates a highly configurable calendar what can be integrate into existing websites. Its stack is composed of various libraries working with a variety of internet standards/RFCs. This project will amongst others improve the support for recurring events. Various widely used Python libraries such as icalendar, mergecal, caldav and dateutil will also receive improvements as well as better documentation to aid developers. Their compliance with the underlying standards will be better tested to cope with the wide range of applications and use cases in the 'wild' - and should improve software quality and stability in millions of installations.

Extensive openwifi support for OpenWRT — Software Defined Radio Wifi for OpenWRT routers

The internet service provider and the IT department are often responsible for setting up your Wi-Fi network at home and work, respectively. As a result, many people take Wi-Fi routers and APs for granted and do not realize that these devices are complex and vulnerable closed black boxes of software, firmware and hardware. The often-outdated software and firmware on these devices, combined with their hardware and overall black box nature, raise serious security concerns. For example, the US is considering a ban on TP-Link devices. The software community addresses this issue through projects such as OpenWRT. However, these OpenWRT devices still route their wireless traffic through a closed Wi-Fi chip.

This project (from the creators of openwifi, the first full-stack open-source IEEE 802.11a/g/n Wi-Fi chip) aims to provide a transparent alternative. The project will deliver fully featured openwifi-on-OpenWRT support for all openwifi-enabled boards. To achieve this, the dependency of openwifi on ADI Kuiper Linux is broken and its hardware description is modularized, allowing us to port openwifi to OpenWRT in a maintainable manner. The result is an openwifi package within OpenWRT, allowing users to choose for both open-source software and Wi-Fi chip, thereby enhancing the security and openness of Wi-Fi routers/APs. With this work, we lay the foundation for future developments, including potential partnerships with open-source Wi-Fi router vendors.

openwifi: 802.11a/g/n maturity — Improved stability, data rate and reach of openwifi

Wi-Fi has become ubiquitous in modern society. While many people might assume that the Wi-Fi chip in AP, mobile devices, and computers is a dumb device that merely sends and receives packets over the air, the reality is far more complex. Even the most affordable Wi-Fi chips are sophisticated heterogeneous computing systems, as highlighted by many researchers and hackers. These chips contain multiple types of firmware and silicon fabric working together. The lack of open-source Wi-Fi chips and the transparency of commercial Wi-Fi chips have raised many security concerns: The security threats over Wi-Fi have emerged for years. Openwifi (https://github.com/open-sdr) aims to address this issue. It is the first open-source soft-MAC Wi-Fi chip/FPGA design, initially released at the end of 2019, with 802.11n added in 2020. As more users, researchers, and hackers engage with the project, they have identified issues related to stability, data rate, and communication distance. This maturity-elevating project aims to tackle these issues through improvements in the Linux driver, FPGA, and RF control. The enhanced version will be comparable to commercial Wi-Fi4 chips, such as the ath9k series, and will be capable of operating in more realistic electromagnetic environments rather than just short-range, controlled environments. These advancements will facilitate broader adoption of the project and lay a solid foundation for future developments, including the creation of a real chip.

Openfire IPv6 support — Add IPv6 support to the Openfire XMPP server

Openfire is an open-source, mature, cross-platform, real-time collaboration server based on the XMPP protocol. Originating around the turn of the century, IPv6 was not explicitly supported when it was originally created. As shown by anecdotal evidence, some IPv6 functionality already ‘works’ in Openfire. This, however, is accidental, and not by design. This project intends to add explicit IPv6 support to Openfire.

Organic Maps сonvergent UI with Qt Quick/Kirigami — Declarative cross-platform UI for navigation

Maps navigation software is a crucial part of computer systems today, be it on Mobile, Desktop, Automotive and so on. For quite a lot time already, we have a brilliant open-source maps application, now named Organic Maps. It's features make it strong competitor to commercial-grade software, among them are: privacy, fully offline maps, low battery consumption, navigation, points of interest (POI) and much more. Currently, the application shows it's strength on mainstream mobile operating systems only. On other systems, it's ability is quite limited, mainly because of lack of proper User Interface for them.

This project aims to create an Organic Maps convergent touch-friendly User Interface for Linux, backed by featured Qt Quick/QML application framework, perfectly suitable for this task. This would allow feature-parity for Mobile and Desktop Linux systems, and also creates solid ground for further unification of the User Interface among other platforms.

PTT — Unikernel Mailing list server in OCAML

Email is still one of the main channel of communication.Setting up and maintaining something as simple as a reliable mailing list in-house is significantly more complex than it ought to be. Out of convenience, many organisations and communities outsource running their maiilng lists service to third-party agents. However, this not only creates an unnecessary dependency but also reduces confidentiality, which can be a critical aspect.

This project has the ambition to win back the means of communication, developing a new mailing list application service that is easier to maintain securely (through unikernels using MirageOS), and is efficient in terms of resource usage. The service should integrate into existing infrastructures seamlessly.

Better support for display notches and cutouts in Phosh — Better custom shape screen support for Wayland

Mobile phones often have notches or cutouts in their displays (often to accommodate the camera), rounded corners or waterfalls (lower resolution areas at the edge of the screen).

The aim of this project is to propose and implement a Wayland protocol that gives applications the necessary information about these areas. This allows them to place UI elements in a sensible and visually pleasing way, color lower resolution areas properly and avoid having important information occluded.

Besides for mobile shells like Phosh this information is also important for e.g. video players and other full screen applications and out of the box support in toolkits is desirable.

Pijul ecosystem — A modern patch-based version control system

Pijul is a modern patch-based version control system that addresses many shortcomings found in existing tools. While its foundations are already mature and well-tested, it lacks many conveniences users expect from the ecosystems of popular tools such as Git. This project aims to significantly reduce Pijul's barrier to adoption by addressing common areas of user feedback - documentation, usability, robustness, and integration into other tools such as text editors or CLI prompts. We believe this will improve the workflow of existing users, and enable many more to adopt Pijul and its benefits without sacrificing other parts of their workflow.

Pijul Hybrid — Hybrid patch-based/snapshot-based system for distributed versioning

Pijul is a modern patch-based version control system that addresses many shortcomings found in existing tools, based on a mathematical theory of collaborative work. In order to ease the transition from existing tools, and increase utility in a wider set of use cases, this project will work on a better transition story from other tools like Git and Mercurial, and improve tooling around it. In particular, it will deliver a hosting platform called Nest which has features which will be quite different from other hosting services. Pijul is able to apply patches independently from each other, meaning that (reorderable) patches can be used in place of legacy pull/merge requests everywhere. This should makes most workflows vastly simpler, as well as result in cleaner code bases.

Pleroma — Scalable ActivityPub server written in Elixir

Pleroma is an extendable ActivityPub communication server. Pleroma can be as light-weight as you want it to be, fit for both running from a homeserver or from more serious infrastructure. Pleroma embraces customization. Instead of trying to dictate how users should use our software, we give them options. From the backend to the frontend, there are hundreds of configurable options to satify the different needs of everyone. We know there's no single setup that works for everyone, and are more than willing to listen to users' feedback. Being part of fediverse of course means interacting with other servers and Pleroma provides the best experience when displaying other types of content, even non-microblogging.

The Fediverse nowadays is a very big place with a lot of different people, who don't necessarily agree with each other or have good intentions. To help with the insurmountable task to moderate the stream of incoming and outgoing content, Pleroma has Message Rewrite Facility, allowing instance administrators to automatically act upon activities including modifying them and deciding whether to show them in federated timeline or not. Having more detailed and partially automated moderation helps create a network where users don't have to worry about not being able to talk to someone else because the admins didn't have the rights tools at their disposals.

Proper Webcam support in Qemu — Better virtualisation of camera interfaces

QEMU is one of the most popular open source machine emulators and virtualizers. It supports a wide range of architectures and is capable of emulating many types of hardware devices. Many people rely on QEMU to run alternative operating systems or even as a secure development environment.

Sometimes it is necessary to pass camera devices to the QEMU guest and make them available to the system. While it is possible to pass cameras using the generic QEMU USB host emulator, this only works with USB cameras and only makes them available to that single QEMU guest. However, many modern systems move away from USB cameras and provide other interfaces for the camera, and thus cannot be passed through.

Our solution is to use the operating system's video API instead to make the video device available. We will focus on providing proper support for the Video4Linux API to emulate a USB video device so that it works with the already existing OS drivers. With proper integration of a camera subsystem, this opens the door to supporting more camera APIs and even extending paravirtualized VirtIO devices in the future to improve video quality for next generation video devices.

RVVM — RISC-V Virtual Machine

RVVM is a virtual machine/emulator for RISC-V guests, which emphasizes on performance, security, lean code and portability. It runs a lot of guest operating systems, including Linux, Haiku, FreeBSD, OpenBSD, etc, and has a rich device infrastructure (Network adapters, NVMe, HID, PCIe with MSI). Emulation performance is very competitive thanks to RVJIT dynamic binary translator. Portability is taken very seriosly and only requires C99 as a baseline. We also aim to run RISC-V applications on a foreign host without full OS guest (userland emulation, i.e. RISC-V containers).

To prevent theoretical VM escape vulnerabilities from being exploited, we enforce kernel-level isolation, strict codestyle and compiler warning policies, extensive static analysis and use of sanitizers/fuzzers.

The RVVM infrastructure is meant to be modular and embeddable - the whole project is contained within "librvvm" library and a reference VM manager to make use of it. GDB debug server is also available for kernel developers and alike. The goal under NGI Zero Core is to implement first-class KVM hypervisor suport for RISC-V, as well as x86_64 & ARM64 hypervisor variant (reusing the same device emulation infrastructure), shadow pagetable acceleration for guest MMU, and RISC-V Vector extension support which is gaining serious traction and is much needed for software testing. Additionally, a special deduplication image format is in the works which should give immense storage benefits in terms of space saved for build farms and cloud use, as well as atomic write consistency for reliability.

Reaction — Event-based system programming

A lot of bots roam the internet, scanning server ports and web endpoints, and filling out any web form they come across - continuously on the lookout for vulnerabilities to exploit. In order to maintain server security, one of the currently most common defense mechanisms is to monitor logs for repetitive behaviour, or specific patterns implying the involvement of bots. With tools like fail2ban, one can write simple rules to automatically isolate machines identified as suspect.

Reaction wants to provide a more modern and efficient approach to regex-based log scanning, allowing multiple reaction instances to communicate, sharing bans across an entire infrastructure as well as more intelligent and user-friendly soft bans. This extends the scope of this class of tooling allowing it to act as a light monitoring tool, or an orchestrator for any other event-based actions.

Real Time Litex Extension — Real time capabilities for FPGA-based RISC-V core

The Core-Local Interrupt Controller (CLIC) is a RISC-V standard extension that enhances real-time performance by enabling the prioritization of interrupts based on levels and priorities. This feature allows developers to have fine-grained control over interrupt prioritization, leading to more efficient handling of real-time events. In this project, we propose to replace the original interrupt controller of the VexRiscv based processor core family with CLIC. By implementing the CLIC, VexRiscv can efficiently propagate the highest-level, highest-priority pending interrupt to the core, significantly improving real-time responsiveness. The CLIC implementation also introduces features like selective hardware vectoring and the special register (xnxti CSR), which further optimize interrupt handling.

NetBSD Reproducibility — Extend Reproducibility for CTF Debugging Infos and NetBSD Image Creation

The NetBSD operating system is built from a single source code repository and supports a great variety of different hardware and CPU variants. NetBSD has a working infrastructure for being reproducible, thus you can verify eg. an install ISO to be created from an untampered repository. As NetBSD is technically always cross-compiled, it can be build on several platforms, most commonly on NetBSD itself and on Linux. This project aims to fix two issues where a Linux-based build host creates different output than a NetBSD host.

Ports using the newer GCC-12 based compiler usually use the CTF debugging format, where the binary representation (probably due to different sorting) differs between Linux and NetBSD builds. The second issue is with install image creation, where symlinks permissions and owner/permission bits from the building host leak into the image, breaking reproducibility. Both of these issues affect the widely used amd64 (usual PCs and Laptops) and arm/aarch64 (Raspberry Pi) ports.

Free and open source NPU Drivers — Libre drivers for Neural Processing Units

As of today, companies that sell components that include accelerators for machine learning workloads (NPU, TPU, DLA, etc) are generally engaged in vendor lock-in practices that interfere with the ability of their customers to freely choose their partners and adapt their software components to their own needs.

This project aims to incentivize providers of accelerating hardware to move to more fair practices by reverse engineering their hardware and writing open source implementations of the corresponding software stack, for interoperability purposes. These drivers become part of projects such as the Linux kernel and the Mesa project, and will become available to users via existing distributions such as Debian, Fedora and NixOS.

SCION Open Source Implementation — Performance improvements for SCION reference Implementation

SCION Open Source is an implementation of the SCION architecture that allows trusted, highly resilient, and path-aware routing infrastructure to be built by ISPs, CDN/cloud providers and enterprises. It supports inter-domain multipath routing by discovering paths between participating Autonomous Systems that can be combined into selectable cryptographically validated end-to-end paths. This provides higher assurances that packets will follow particular paths which can prevent route leaks and hijacks, and allow data to be geofenced thereby ensuring compliance with legislation such as GDPR and NIS2. SCION also supports fast multi-path discovery and fast failover as its path discovery process does not rely on BGP iterative convergence or forwarding table updates. Having a performant and robust open source implementation ensures there’s a viable alternative to commercial and closed source implementations which is pre-requisite for some large potential adopters.

SCION-enabled IPFS and libp2p — Enhancing IPFS Performance and Resilience through SCION's Path-Aware Networking

SCION is a clean-slate Next-Generation Internet (NGI) architecture which offers a.o. multi-path and path-awareness capabilities by design. Moreover, SCION was designed to provide route control, failure isolation, and explicit trust information for end-to-end communication. As a result, the SCION architecture provides strong resilience and security properties as an intrinsic consequence of its design. The goal in this project is to leverage the path-awareness in SCION to align the storage and lookup in IPFS with the underlying network in an optimal manner, while at the same time using SCION to establish trust between the entities.

SMAesH-Mode — Side-channel protected hardware implementation of AES

The security of internet devices relies on cryptography for many features such as secure communications, secure boot or user authentication. In many cases, the underlying cryptographic building blocks are implemented in hardware for efficiency and/or security reasons. Further, many devices can be attacked through physical side-channel leakage such as power consumption or electromagnetic emanations (EM). Critically, these attacks do not strictly require direct physical access to the device, and attack based only on remote physical access have been demonstrated (e.g. EM a few meters way).

Nowadays, AES remains a fundamental block cipher in most security solutions. In this context, SMAesH is a open-source side-channel protected hardware implementation of the AES that could be used in secure micro-controllers for direct use in protocols that rely on AES, or as a building block for secure storage. However, a block cipher is rarely used alone, and is instead integrated in a mode of operation that provides confidentiality and/or integrity, which are currently not supported by the existing SMAesH IP.

This project mainly aims at extending SMAesH to include support for common modes of operation (GCM, CBC and CTR). Besides, our goal is to make SMAesH easy to integrate with open-source hardware designs by implementing a standard TileLink bus interface.

Scheme Testing Framework — Modernise testing for Scheme

This project addresses a critical gap in the Scheme ecosystem by delivering a comprehensive and extensible testing framework that will serve as foundational infrastructure for current and future development. The Scheme family of languages powers numerous important projects in reproducible builds, decentralized systems, and security-critical applications, yet lacks a modern, well-designed testing solution compatible with today's development practices. Our library bridges this gap, enables interactive testing workflows with immediate feedback for REPLs and IDEs while supporting automated CI/CD pipelines through standardized interfaces. By creating SRFI specification with an implementation-agnostic design, proper test isolation, and metadata-driven test runners, we will empower developers to build more reliable software across the entire Scheme ecosystem. This contribution in core development infrastructure will strengthen existing projects, lower barriers to entry for newcomers, and enable the next generation of Scheme applications.

Secure Web Tokens for Linux — TPM 2.0 backed FIDO2/U2F tokens on Linux

This project aims to develop a systemd daemon that utilizes the TPM 2.0 security chip to provide FIDO2/U2F tokens for web browsers and operating system applications on Linux. Leveraging the ubiquitous presence of TPM2 in modern PCs, the daemon will enhance security and usability for Linux users. It will allow the integration of security chips as access tokens with web extensions, secure local passwords and HOTP/TOTP managers, and enable hardware-based lock screen authentication mechanisms.

The daemon will interface with the TPM2 chip to manage FIDO2 token generation. It includes support for the "uhid" kernel driver for button press emulation when no fingerprint reader is available for authentication. The project involves developing the daemon, ensuring seamless integration with systemd, and conducting extensive testing for functionality and security. Comprehensive documentation will be provided for setup and use, along with user guides for web extension integration. The outcome will be a robust, secure, and user-friendly solution for Linux users, elevating the baseline security and leveraging existing hardware capabilities to the fullest.

SelfHostBlocks — NixOS based server management for self-hosting

It is obvious by now that a deep dependency on proprietary service providers - "the cloud" - is a significant liability. One aspect often talked about is privacy which is inherently not guaranteed when using a proprietary service and is a valid concern. A more punishing issue is having your account closed or locked without prior warning. When that happens, you get an instantaneous sinking feeling in your stomach at the realization you lost access to your data, possibly without recourse.

Hosting services yourself is the obvious alternative to alleviate those concerns but it tends to require a lot of technical skills and time. SelfHostBlocks (together with its sibling project Skarabox) aims to lower the bar to self-hosting, and provides an opinionated server management system based on NixOS modules embedding best practices. Contrary to other server management projects, its main focus is ease of long term maintenance before ease of installation. To achieve this, it provides building blocks to setup services. Some are already provided out of the box, and customising or adding additional ones is done easily.

The building blocks fit nicely together thanks to contracts which SelfHostBlocks sets out to introduce into nixpkgs. This will increase modularity, code reuse and empower end users to assemble components that fit together to build their server.

Servo: Benchmarking and Statistics — Infrastructure for benchmarking and testing Servo

Servo is a web engine written in Rust that already provides results from the Web Platform Test Suite. However, these results may be difficult for newcomers to understand, as they lack a clear indication of the progress in supporting modern web standards. This creates challenges for the community in assessing the current state of development. When the community inquires about the support for specific features, these capabilities can often only be verified through manual testing. Moreover, finding information about Servo's performance can be equally challenging.

To address these issues, this project aims to develop an infrastructure to benchmark and report on the current state of Servo, monitor performance differences between commits, and present these metrics and supported features in a more comprehensible way. This will give the community a clearer understanding of the state of the Servo project, leading to a more active and engaged contribution environment.

Multiprocess Mode in Servo — Speed up Servo with parallelisation

While Servo already has multi-process mode, it’s not enabled by default. The main reason is that it isn’t completely supported on every platform yet. Only Linux and macOS have full support. It also isn't tested in the WPT suite. In this project, we want to complete the feature set of multi-process mode in Servo, set it to default, and encourage other projects based on Servo (like the Verso browser) to use it, as they could massively benefit from this multi-process architecture.

Servo Script Improvement — Refactoring Servo’s script crate

The Servo web browser engine is back to its pace of development, but many improvements are still needed in Servo's script crate, which needs to adequately implement every Web API. Several DOM structures have become slightly outdated because of the lack of maintenance. Some basic script types are missing, and patches from Spidermonkey still need work. Within the scope of this project we will address the most needed fixes and improvements for the script crate.

SocksTrace — Ptrace based proxy leak detector

Proxy leaks are a class of software vulnerability in which network traffic intended for a proxy (e.g. Tor) is instead sent without a proxy, risking the deanonymization of the user. Auditing software for proxy leaks is presently nontrivial, e.g. tools like tcpdump and Corridor generally require invasive privileges, cannot audit for stream isolation leaks, and provide limited diagnostic capabilities. SocksTrace is a proxy leak detection tool, suitable for CI testing or manual QA testing, that utilizes the ptrace feature of Linux to detect socket syscalls that would bypass a proxy. If a proxy leak is detected, SocksTrace can respond by (among other things) denying the syscall, redirecting the connection to a proxy, or logging a stack trace. SocksTrace is written in Go, making it memory-safe and securely bootstrappable.

Solid NC 2024 — Add more Solid capabilities to Nextcloud

The Solid Nextcloud project implemented a server component with the Solid specification for Nextcloud, which makes ones Nextcloud server a Solid server as well. This allows user to user their existing server for identity and storage within the Solid eco-system.

To enhance security and to enable easier cooperation and release of new versions we need to improve a number of things. The CI/CD of the project will be improved. Based on an earlier audit, we will implement a number of security enhancing features and we will release a PHP Solid Server next to the Solid Nextcloud module. These servers share a lot of code, which makes maintenance easier. The advantage is that PHP has a security maintenance cycle of three years, making it easier for users to stay secure when using a Solid server.

Solid Application Interoperability — Easy to deploy authorization for Solid Applications

Solid Application Interoperability specification details how Agents in the Solid ecosystem can read, write, and manage data stored in a Solid pod using disparate Applications, individually or in collaboration with other Agents. Solid is a specification that lets people store their data securely in decentralized data stores called Pods. Pods are like secure personal web servers for data. When data is stored in someone's Pod, they control which people and applications can access it. Solid Application Interoperability provides a clear way to create intuitive data boundaries and higher-level patterns to manage access to that data following the principle of least privilege.

This project focuses on finalizing the enforcement of user-defined access policies and improving related user experience (UX), development experience (DX), and deployability.

Solid Project was founded by Tim Berners-Lee and is currently stewarded by the Open Data Institute (ODI). Incubation of technical reports happens in the W3C Solid Community Group. Some drafts have already been provided as inputs to the W3C Linked Web Storage Working Group which is chartered to publish final specifications.

Spade — Standalone Hardware Description Language

Spade is a hardware description language that draws inspiration from modern software languages to make hardware development more productive, more fun, and less error-prone. A big part of what makes this possible is the type system which helps prevent bugs and makes the code more maintainable.

A common source of errors in hardware designs is clock domain crossing: signals should never cross domains accidentally, and when they do cross, it must be done correctly. Failures to correctly cross domains leads to intermittent problems that can take significant effort to find and fix. By making the language and compiler aware of clock domains through the type system, we will be able to detect and warn programmers about accidental clock domain crossings at compile time. We will to do this in an ergonomic way, where the user only has to specify clock domains on module inputs and outputs with the compiler being able to infer the rest. In addition, the default case of a module that only spans a single domain should not require any explicit domain information form the user to avoid unnecessary verbosity.

Transitioning SMM Ownership to Linuxboot — More robust defense Against Firmware Vulnerabilities

In an era marked by escalating cybersecurity threats, firmware security is one of biggest blind spots. One pervasive weakness lies in an architectural design called System Management Mode (SMM). Sometimes referred to as “Ring -2”, SMM is used by device manufacturers to interact with hardware like NVRAM, emulate hardware functionality, handle hardware interrupts or errata, and perform other functions.

The unrestricted, non-standardized control inherent to SMM implies significant security vulnerabilities. There is no shortage of Day-0 and Day-1 Firmware vulnerabilities related to SMM. Current industry practices open a wide door for cyber attacks, and the attacker can even bypass the secured OS kernel with the SMM loopholes.

This proposal introduces a novel SMM architectural design, by transitioning SMM ownership from core firmware (e.g. coreboot) to payload - in this case Linuxboot. This will leverage the robust, open-source nature of Linux’s SMM drivers, as its drivers that has been proven working very well over decades, and its open source nature made it easier for security reviews. This initiative aims to develop and universalize a secure architectural design in collaboration with chip vendors, and thus elevating the resilience and integrity of our digital ecosystem.

Standards Grammar Catalog/Toolchain — Open Standards Grammar Catalog/Toolchain

The Open Standards Grammar Catalog/Toolchain makes it easier to implement a format or protocol by translating its machine-readable definition, usually in a language such as ABNF, into forms readily compatible with popular programming languages, like regular expressions, YACC, ANTLR, and native code. By providing a toolchain for making these translations, assembling a catalog of commonly used formats & protocols, and publishing a developer-friendly website for browsing the grammars and generating translations, these tools will reduce the need to manually write a parser, ultimately reducing errors due to hand-written code, and enhancing interoperability.

TSCH-rs — Time Slotted Channel Hopping implement in Rust

Time Slotted Channel Hopping (TSCH) is a Medium Access Control (MAC) layer protocol described in IEEE 802.15.4e designed for low-power and lossy networks. Devices are allocated time slots in which they can transmit and/or receive frames. The rest of the time the radio is turned off, reducing energy consumption. Consecutive transmissions are done on different frequencies to tackle interference. Implementations of TSCH can be found in Contiki-NG and OpenWSN, both written in C.

TSCH-rs is a TSCH implementation written in Rust, providing ease-of-maintanance, security and reliability. Furthermore, the implementation aims to be hardware-agnostic, making it easy to port to different IEEE 802.15.4 based radios. The Rust network stack for IEEE 802.15.4 radios already contains an implementation for 6LoWPAN and RPL. TSCH-rs will be a valuable addition to the Rust based low-power IEEE 802.15.4 network stack.

Tau — Remote sharing of terminal sessions

A common problem among people working on a command-line interface is to share their terminal session with one or many other people via the internet, ideally along with an audio stream, without viewers having to install any specific software. This project creates a solution that enables anyone with a web browser to receive such a broadcast.

Unlike generic screensharing alternatives, a broadcast created by .tau will not be a stream of compressed video but rather a stream of ASCII characters with preserved timing as well as the broadcaster's terminal look & feel, and giving the ability to easily copy text. The broadcaster will have a nice and easy experience installing a piece of software which accomplishes this.

Upon completing a broadcast, a single resultant file is available for later viewing on the internet and or private distribution. Simple, portable and robust.

Titanic — Database server to synchronize vast collections of CRDT documents

Yjs is a Conflict-free Replicated Data Type (CRDT) which enables developers to build collaborative applications, just like Google Docs and Figma. Most CRDT implementations work just like any other data type, but they automatically sync with other peers without conflicts. Today, Yjs is among the most used technologies for building collaborative applications.

The developers observed the development of competing CRDTs, and recognize the need for more specialized CRDTs for specific use-cases. Syncing many CRDT instances with different permissions is still an unsolved problem. Syncing documents individually quickly becomes infeasible with an increasing number of documents in a local-first app.

This project will therefore develop Titanic, an isomorphic database (works in the browser, Node.js, Deno, Bun, ..) that can host different CRDT implementations. It will sync many CRDT instances efficiently in a network-agnostic manner. While it will support custom authentication approaches, Titanic will ship with a role-based document-level permission system that prevents unauthorized users from reading or writing documents.

Verso Views — A Functional Browser Based on Servo

Verso is a web browser based on Servo web engine. While Servo hasn’t been treated as a fully functioning browser, it is possible to build one based on it already. We plan to expand this into a formal and stable application release, eventually implementing the features, making it not just a general browser application but also a webview library for embedding purposes.

There are some missing features we still need to push into Servo. And there are also other works that require time and resources to make a barebone web engine into a stable application. We hope to take this project as a chance to finally make an individual repository using Servo as a dependency. In this way, Servo can focus on issues and features of the web engine itself. In the meantime, other chores related to the application itself can be off-loaded to other repositories and organizations.

Webview library with Verso for Tauri — Refactor parts of Verso into a WebView library

We aim to publish the Verso browser as a library in addition to the current application approach. This way other projects could use it as a dependency in their software, and render their content with it. The distribution of a shared library is a challenging set of problems (including, but not limited to bundle format, code signing, dependency linking, etc.) that we intend to solve. We also aim to find the best possible solutions to help developers use this library with ease. One of these approaches will be to integrate with Tauri as a webview backend.

Vouivre — A dependent type system for machine learning in Lisp

Current machine learning frameworks are built around relatively weak type systems. This is a problem because, at scale, machine learning applications are exceedingly intricate and computationally expensive, therefore making costly runtime errors unavoidable. This is where Vouivre comes into play. Using a dependent-type system, the project aims at enabling users to write machine-learning applications that solve real-world problems with compile-time validation of their correctness, thus preventing runtime errors at a reasonable computational cost.

Enhance the vulnerability database — Enhance the VulnerableCode vulnerability database

Using Components with Known Vulnerabilities" is one of the OWASP Top 10 Most Critical Web Application Security Risks. Identifying such vulnerable components is currently hindered by data structure and tools that are (1) designed primarily for commercial/proprietary software components and (2) too dependent on the National Vulnerability Database (funded by the US CISA and Dept. of Commerce). With the explosion of Free and Open Source Software (FOSS) usage, we need a new approach in order to efficiently identify security vulnerabilities in FOSS components that are the basis of every modern software system and applications. And that approach should be based on open data and FOSS tools.

This project delivers unique FOSS tools to aggregate software component vulnerability data from multiple sources, privileging upstream data directly from project maintainers. VulnerableCode organizes that data with a de-facto industry standard Package URL identifier (Package URL or PURL) enabling efficient and straightforward automation for the search for FOSS component security vulnerabilities. The benefits are to contribute to the improved security of software applications with open tools and data available freely to everyone and to lessen the dependence on a single foreign governmental data source, or a few foreign commercial data providers.

In the new context of the upcoming Cyber Resilience Act (CRA), the access to an open, free and curated FOSS package vulnerability data source is now an imperative. And the organization of vulnerability data by Package URL or PURL identifiers in VulnerableCode enables easy frictionless integration with Software Composition Analysis (SCA) code analysis tool chains, direct enrichment of SBOMs (Software Bill of Materials) to find if SBOM-listed packages have known vulnerabilities, and creation of VEX (Vulnerability Exploitability Exchange) document to communicate the impact of known vulnerabilities

WPE Android — Embedded-friendly Webview based on WebKit

WPE (Web Platform for Embedded) is a WebKit port for Linux-based embedded devices with a focus on flexibility, security and performance on lower-powered devices. Albeit less known than Chromium, Firefox or Safari, WPE is currently deployed in millions of embedded devices (e.g. set-top-boxes, smart home devices, kitchen appliances, infotainment, etc), but it hasn't yet reached those based on the Android Operating System, which has become an important actor for certain types of devices, such as phones, tablets, set-top-boxes and even IoT devices.

In such environments, the only option currently available to leverage the power of the Web Platform is to use Android's WebView, which is based on Chromium and therefore problematic in cases where using that is not an option. By bringing WPE to Android in the form of an Android WebView-compatible component, we aim not just to make WPE available in more platforms but also to expand the options Android developers currently have so that they can choose between a Chromium-based WebView and a WebKit-based WebView for their applications. This would be great to cover Web rendering needs in general on Android, and particularly beneficial for multimedia-intensive use cases (e.g. set-top-boxes, digital signage...), as well as for other less conventional use cases such as QA & testing (e.g. testing WebKit-based browsers on Android based systems).

Last but not least, as a side effect of widening the reach of WPE to Android-based devices, we believe that we would also be bringing more balance and diversity to the Web, by making sure that developers have a realistic alternative to the Chromium-based Web rendering engine they can use to develop their products.

WPT automatic testing for platform accessibility mappings — Improve testing of platform a10y support in Web Platform Tests

In order to support assistive technology (AT), web browsers must provide information about web pages' contents via OS-specific accessibility APIs. The Accessible Rich Internet Applications (ARIA) suite of standards includes specifications concerning how browsers should translate the web page contents into each supported API. To date, these Accessibility API Mapping (AAM) specifications have not been tested in a standard way across browsers. This project will help extend the primary test suite for web standards (https://web-platform-tests.org/) to allow for testing of accessibility APIs. The project also includes writing tests for the Linux accessibility API mappings. With these addition to the test suite, we will be able to find interop bugs between browsers and web developers will be able to understand the status of browser support for accessibility features they want to use on the Linux platform.

Wayland input method support — Better specification for Wayland input methods

As Linux distributions switch to Wayland, some functionality is still incomplete. One of them is being able to input non-Latin scripts. It is a necessity for a large portion of the world, yet it's not standardized across Wayland environments. The same text input functionality is needed for typing on mobile Linux, which, considering how many people use smartphones rather than laptops, might be even more important for Linux adoption. This project wants to bridge that gap, by continuing the effort of standardizing input-method protocols started for Phosh in Squeekboard, gtk, and wlroots.

Zero-allocation web servers in roc — Web server framework with constant memory usage

Memory consumption in web servers is hard to predict and control. Our zero-allocation web server guarantees constant memory usage and per-request memory caps. These guarantees and capabilities make web infrastructure more reliable, because it is actually possible to calculate how much server capacity is required for a certain amount of traffic.

The vast majority of webservers are written in a language with automatic memory management. They cannot provide the guarantees that our webserver can, and often have other downsides like poor general performance and GC pauses.

The core of our webserver is written in rust, and while it works in a rust-only context, is meant to be used in combination with the roc programming language, a fast, friendly, functional language with automatic memory management, but without GC pauses. Users will be able to write web applications using roc, without having to consider how memory is allocated. At the same time, we manage the memory as efficiently as possible under the hood.

Zip linting and bzip2 in Rust — More secure handling of popular archive formats

Zip is a widely used format for distributing files. It is a rather permissive file format, opening the door to various attacks such as zip bombs. The `bzip2` compression format is still used in many legacy settings. Consequently, it is part of the supply chain of many projects. To mitigate these risks, this project will deliver a) a zip linter checking for suspicious file contents in zip files and b) a memory-safe implementation of bzip2 through drop-in replacements of the libraries and a safe Rust `bzip2` binary.

f8 — Modern 8-bit instruction set

Among microcontrollers (µC), 8/16-bit µC are an important part of the embedded systems ecosystem since they tend to have substantially lower resource and energy costs than the larger, more powerful 32-bit and 64-bit µC.

However, existing 8/16-bit µC architectures tend to be either somewhat inefficient (e.g. MCS-51) or single-vendor (e.g. STM8, Rabbit). The latter are at a high risk of being discontinued when a vendor pulls out of the 8/16-bit market, and this has been announced recently for the STM8 and Rabbit architectures. One possible solution is to develop an efficient free architecture for 8/16-bit µC. The f8 is such an approach. It is based upon extensive experience from the large number of 8/16-bit architectures supported by the free Small Device C compiler (SDCC). Like RISC-V did for 32/64-bit architectures, f8 is based on lessons learned from the strengths and weaknesses of existing 8/16-bit architectures.

foaHandler — Reverse engineer the OpenAccess file format

Commercial CAE programs still dominate the community that designs electronic circuits. One of the most widely used file format here uses the OpenAccess API controlled by Si2. Unfortunately, this API is available only for members of the OpenAccess coalition. The project "foaHandler" aims at creating open-source programs for reading and writing OpenAccess files. Their internal data structure will be investigated by reverse engineering the file content of schematics, component symbols and layouts. Then, routines will be created that make it easy to import and export OpenAccess files in open-source programs like circuit simulators, layout programs etc. Example files and documentation will be published, too. This makes the data exchange between free and commercial EDA applications possible.

k3lp — Unicode Keyboard3 Layout Parser

k3lp (/kɛlp/) is a mobile-first library designed to support parsing and utilizing Unicode Keyboard3 files. Keyboard3 is an enhanced and rewritten standard developed by The Unicode Consortium and officially released with CLDR 45. It offers an open and interoperable standard for declaring and sharing keyboard layouts. Although the standard has been available for some time, there is currently no ready-to-use open-source library to effectively utilize these files. This is where k3lp comes into play, aiming to provide an easy-to-use, multi-platform library written in Kotlin 2.0. The library includes all the necessary business logic for layout parsing and streamlining keyboard developers' workflows, however the actual user interface implementation is left to the library consumer. Initially targeting Android and iOS developers in need of keyboard layout logic and tested in the open-source FlorisBoard keyboard, this library is capable of running on all platforms where the JVM runs on or where Kotlin compiles to.

lib1305 — Microlibrary for Poly1305 hashing

In modern network protocols, every packet is authenticated using a message-authentication code (MAC). Any data modified by an attacker is immediately caught and rejected by the MAC. The most popular MAC algorithms are Poly1305, normally used with the ChaCha20 cipher as part of ChaCha20-Poly1305, and GMAC, normally used with the AES cipher as part of AES-GCM. Many applications, such as WireGuard, require specifically Poly1305. This project will develop and release a new software library, lib1305, for Poly1305. The library will provide comprehensive and well-optimized software exploiting the 64-bit assembly instructions of Intel CPUs to provide top speeds for those CPUs, while meeting the security constraint of not leaking secret information through timing.

lib25519 using NEON for ARM64 — ARM64 optimisations for lib25519 microlibrary

Network protocols in today's world rely on elliptic-curve cryptography (ECC) to protect communication against espionage and sabotage. lib25519 (https://lib25519.cr.yp.to) is a software library for the Curve25519 elliptic curve (https://cr.yp.to/ecdh/curve25519-20060209.pdf), including the X25519 encryption system and the Ed25519 signature system. Curve25519 is the fastest curve in TLS 1.3, and the only curve in Wireguard, Signal, and many other applications (https://ianix.com/pub/curve25519-deployment.html). Currently the optimizations in lib25519 use serial instructions and vector instructions for Intel and AMD CPUs, and use serial instructions for ARM CPUs, but do not use vector instructions for ARM CPUs. This project aims at exploiting the NEON vector instructions of 64-bit ARM CPUs and extend lib25519 by providing top speeds for those CPUs, in particular setting new speed records for X25519 key generation and Ed25519 signing, while meeting the security constraint of not leaking secret information through timing.

libvips — Add animated PNG and enhanced JPEG XL support to libvips

libvips is an image processing meta-library, whose development the European Commission funded back in the 1990s. Applications can outsource the heavy lifting of handling a variety of image types to this library. The library has meanwhile grown very popular with web developers around the world; the node binding, for example, is downloaded more than 5 million times a week at the time of writing.

In addition to scrutinizing the security of the library, this project will implement two key improvements to libvips: animated PNG support, and enhanced JXL support. The former capability (the addition of animated PNG support) can be gained from another NGI Zero project, libspng. libvips uses libspng for PNG read and write, so by extending libvips to use these new libspng features, they will become available to a large developer community very quickly.

Second, libvips has had preliminary support for the JXL format since libjxl v0.4. Since then, the libjxl API has evolved considerably and the libvips connector needs updating, especially in the areas of large image support and HDR, both increasingly important with the steady improvement of smartphone cameras.

Lychee — Reliable and fast link checker to combat linkrot

Links are the glue that holds the web together, but broken links undermine our collective digital knowledge. With 54% of Wikipedia references and 70% of links in legal journals now dead, link rot is a serious threat to information accessibility and makes for an unpleasant web experience.

Lychee is a fast, memory-efficient CLI tool written in Rust that detects broken links in Markdown, HTML, and plain text. Over the past 4 years, it has been adopted by tens of thousands of public repositories and organizations like Google, Microsoft, and AWS. The project will focus on three key milestones: implementing recursion support to check entire websites at once, adding per-host rate limiting to prevent server overload and sabilizing the codebase for a 1.0 release. By improving Lychee, we're helping everyone from small websites to major platforms maintain their corner of the open web and preserve our digital heritage.

machine-check — Tool for formal verification for machine-code

Common bug-finding approaches like software testing do not guarantee the absence of bugs. Formal verification can prove the absence of bugs, but the added description and proving complexity means it only tends to be used for critical systems. The current state-of-the-art tools are complex to use and hard to reason around when they fail. Machine-check aims to bring scalable yet intuitive formal verification to non-experts, leveraging the Rust ecosystem for description of digital machines including processors with machine-code programs loaded into memory. Ultimately, this should lead to increased reliability, safety, and security of programs and systems.

Multisoni — Modern and efficient real-time audio playback engine

Multisoni is a versatile audio engine for all creative uses. For demanding real-time uses (such as video games, VR, live installations) there is a lack of free/libre audio authoring tools to map playback and effects to trigger events and interaction parameters, suitable for industrial purposes.

Multisoni is designed to meet this need: it manages many input sources - either samples or synthesis, with support for input plugins - source and effect patching, and rendering for a variety of output systems ranging from binaural stereo to complicated multichannel setups, drawing on existing open-source solutions for audio hardware abstraction and raw audio stream management. One of its main objectives is to put creative users - sound designers, composers - on an equal footing with developer users.

openPCIe2 Root Complex — Open hardware implementation of gen 2 PCIexpress in OpenXC7

This project will develop an open hardware implementation of PCIexpress 2.0, the high-speed serial computer expansion bus standard used to allow computer peripherals to be slotted into a motherboard. When designing open hardware, having such a critical part of a component depend on proprietary components is obviously . The open hardware PCIe/Gen2 Root Complex developed within this project would make a big step towards developing fully open hardware components. Prior efforts only provided a partial implementation, and depended on vendor-provided 'black boxes' that would prevent such designs to be used to create a working, fully open hardware solution.

postmarketOS: v23.12 and v24.06 Releases — New versions of the mobile operating system postmarketOS

postmarketOS keeps smartphones useful after they don't receive updates anymore: the original operating system gets replaced with an up-to-date lightweight open source software stack based on Alpine Linux. Oftentimes people use postmarketOS to upcycle their old smartphones to small home servers (like Raspberry Pis). While still experimental, we also work towards enabling all typical smartphone features too so postmarketOS can fully replace the original operating system. Besides extending the lifetime of smartphones, in postmarketOS we value the user's privacy, security and in general control over their own device. Unlike current mainstream smartphone operating systems, it is not needed to register an account and get tracked to use the operating system. Creating new releases allows us to keep the software stack up-to-date, to integrate important fixes, features and in general to get closer to provide a full smartphone experience.

Support for OpenPGP v6 in rPGP — Implement draft-ietf-openpgp-crypto-refresh in rPGP

rPGP is a high-quality implementation of OpenPGP in pure Rust (OpenPGP is a standard for encryption, digital signatures and key management). rPGP is used in production in different contexts, among them the popular "Delta Chat" decentralized and secure messenger that is used by hundreds of thousands of users, worldwide. The OpenPGP standard has recently been revised to reflect current best cryptographic practices. The revision of the standard defines "OpenPGP version 6" and is currently being finalized  for publication as RFC 9580. This project will implement the new formats and features of OpenPGP v6 for rPGP. This will bring the new features of OpenPGP v6 to users of rPGP, and ensures future interoperability with all other modern OpenPGP implementations.

reqwest — Memory safe HTTP client

reqwest is the de-facto HTTP client for the Rust language, with batteries-included. In this project we will make many of its powerful features to be composable and reusable outside of reqwest. This includes converting its connection pool, proxying and redirection into middleware, and improving integration with existing middleware, such as retries. This ultimately enables two groups of people: some so they can use only the parts of reqwest they need. And others that want to use all of reqwest while inserting new middleware or customizing its default "stack".

s6-rc — Service manager for s6-based systems

The s6-rc service manager, part of the s6 ecosystem, is a correct and efficient alternative to software managing boot scripts like sysv-rc or OpenRC: it provides a bootability guarantee, a reliable logging infrastructure, parallel service start without race conditions, and the lowest resource usage of all existing service managers (which means it is very fast and will run on the smallest systems). However, it is not yet adopted by many Linux distributions, for lack of a high-level user interface and pre-provided boot scripts.

We are adding these features to s6-rc so it can be easily integrated to more distributions currently relying on OpenRC, such as Alpine Linux, and also targeted as a backend for service description languages for use with automatic deployment to containers, VMs, clusters, or embedded systems. The goal is to make s6-rc an accessible and widely known service management alternative for fast, reliable and energy-friendly system deployment.

Maintenance and portability of sudo-rs — Make sudo-rs available cross-platform

The sudo and su utilities guard a critical privilege boundary on just about every free and open-source operating system that powers the Internet. Memory safety bugs occur in the original sudo from time to time, and there is only one maintainer to fix them. For these reasons sudo-rs was written: a Rust drop-in replacement for sudo on Linux. For it to be a success, it needs to gain adoption. In this project, we will 1) address bugs and incompatibilities between sudo-rs and sudo and 2) port it to platforms other than Linux, to grow its user base and viability.

synit-nixos — Expand synit system layer and integrate in NixOS

Much of the software applications and services that we interact with today can only exist as dynamic compositions of many different software components. Dynamic systems can be adapted to serve different purposes, react to a changing environment, and can be self-updating or self-healing in response to failure. These systems exchange the predictability of static systems for the resilience of dynamism.

Our software operating systems achieve dynamism by what some call the "system layer". Traditional this would be the so-called "init" system which activates different software components. The system layer is the software activation and management of init combined with a communication layer, reactive behavior, and system introspection. Synit is an experimental system layer that provides these features according to a model that combines capability security, conversational actors, and eventually-consistent replicated state.

The Synit-NixOS project aims to bring init and system-layer portability to NixOS with Synit as an alternative to systemd.

uFork/FPGA — A memory-safe pure-actor processor soft-core

uFork is a novel microprocessor architecture based on dispatching immutable asynchronous message-events to reactive objects (actors) which manage private mutable state. Contention for shared mutable storage is eliminated, reducing complexity. Strong process and memory isolation prevents interference among tasks. Object-capability security (ocaps) provides fine-grained access control. The architecture has been validated by implementing a virtual-machine in software. This project will implement the design using FPGA hardware fully supported by open-source tooling.

uberClock — High precision open hardware clocks using multi-mode crystal oscillators

Very precise clocks have many different use cases, but they are complex to make and expensive to buy - leaving high precision timing out of reach for many. Currently, there are no open hardware designs capable of delivering so called "Stratum 2" accuracy.

This project will design and build an open hardware clock exploiting the properties of multi-mode crystal oscillators using modern numerical methods for frequency stabilization. A Field-Programmable Gate Array (FPGA) will be used for digital signal processing functions, multiple Proportional-Integral-Derivative (PID) control loops, and executing all necessary calculations needed for dynamic, real-time frequency corrections. High-Level Synthesis (HLS) code will be developed using the CflexHDL+PipelineC toolset, in order to validate and further mature that emerging design flow for signal processing applications.

vm-builder — Virtual Machine Build, Life Cycle and Integration in monolithic and microkernel platforms

As each piece of software is built using other software, it is difficult to ensure that a program is not accidentally infected through malicious code interfering anywhere in this process. An important defence is reducing the amount of code one relies upon and strictly isolating the build from any other processes that could influence it, typically by using a virtual machine.

However, the are currently no minimal, portable and final virtual machine build systems which enable effective bootstrapping of operating systems. Delegating this task to container build systems is insufficient, since they are primarily available to the Linux kernel and provide weak isolation properties. Delivering those with a high portability and even (or especially) on low TCB microkernels is key to secure bootstrapping of operating systems and applications on (to be) trusted infrastructure.

The current prototype has proven successfully applicable to nowadays general purpose OSs, templating/inheritance and reproducible builds are to be implemented. An implementation in a more robust programming language like Rust is still lacking and will be completed in the course of this project. The long term goal is to easily build and provide legacy platforms and software especially on microkernels — allowing for a migration path towards operating systems with effectively manageable complexity.
