Our mission is to provide uniquely comprehensive, system-level testing that ensures the integrity of everything from single OS images to complex, multi-machine service stacks. In this 10-minute lightning talk, we will provide a high-velocity update on the major advancements made within the QE ecosystem over the past year(s). We will cover key updates across our two primary domains: dev: openQA - upstream os-autoinst+openQA and related open source QA tooling and operating openQA on o3 – infra: QE infrastructure - OSD, o3 OS and base, qem-bot/qem-dashboard, hardware, compliance, etc. - SUSE specific solutions Licensed to the public under https://creativecommons.org/licenses/by-sa/4.0/ about this event: https://c3voc.de Thu, 25 Jun 2026 11:45:00 +0200 https://cdn.media.ccc.de/events/osc/2026/webm-sd/osc26-5170-eng-Evolution_of_the_openQA_Ecosystem_webm-sd.webm?1783617051 gnkePUy27ZZn0WliIT5bcg 2026-06-25T11:45:00+02:00 Oliver Kurz No 5170, 2026, osc26, openSUSE, Gallerie, osc26-eng, Day 1 Changes since the last years As the SUSE QE Dev and Infra teams, we maintain the primary open-source testing pipelines that power openSUSE distributions as well as SUSE products.

MariaDB security should be strong, automatic, enabled by default and easy to use. This talk will explain new security features in MariaDB client-server protocol — zero-configuration SSL and PARSEC authentication plugin. The first feature allows all MariaDB connections to be automatically encrypted with full end-to-end certificate verification without CA signed certificates or, really, any SSL configuration whatsoever. The second introduces a new trustless authentication protocol with built-in protection against brute-force, replay, and precomputation attacks. Keeping your connection secure from Man-in-the-Middle attacks is not optional in 2026. MariaDB takes the complexity out of it. You do not need to do anything — it just works.

This talk presents grommunio as an open, enterprise-grade alternative to Microsoft Exchange, with a strong focus on the technology behind making it usable out of the box. The session will show how grommunio builds on the openSUSE ecosystem to deliver a complete collaboration appliance based on openSUSE 16.0, using KIWI to create a reproducible, maintainable, and deployable system image. Rather than only discussing groupware features, this talk goes behind the scenes: how the appliance is assembled, how openSUSE provides the operating system foundation, and how grommunio packages email, calendaring, contacts, mobile synchronization, Evolution/Thunderbird/Outlook compatibility, and administration into an integrated enterprise experience. A key focus is the out-of-the-box experience: turning a powerful open source software stack into a product that can be installed, configured, and operated by real organizations. The talk highlights how openSUSE technologies enable a reliable appliance model, how grommunio delivers enterprise collaboration on top of it, and why this matters for organizations that want to reduce vendor lock-in without compromising usability or professional requirements.
