SELinux - current state in (open)SUSE (osc25)
SELinux is a Mandatory Access Control (MAC) system that enhances a system's security by enforcing policy-based access control rules. For a long time openSUSE and SUSE have relied heavily on AppArmor as default MAC system. With the decision to switch to SELinux as default MAC on SLE 16 and openSUSE Tumbleweed, there are multiple challenges that we have to overcome to integrate SELinux into those distributions. This session will give an overview on the current state of SELinux in openSUSE and SUSE, the plans for the future and what it means for users. Licensed to the public under...
Linux schedulers for fun and profit with SchedKit (osc25)
The Linux kernel scheduler is a critical component, profoundly impacting system performance and responsiveness. Traditionally, changing the scheduler has involved recompilation, rebooting, or complex kernel module management – a significant barrier for experimentation and fine-grained performance tuning. SchedKit dramatically simplifies this process, enabling users to dynamically switch between schedulers at runtime, without reboots or kernel modifications, opening up new possibilities in customizing kernel scheduling for the specific usecase. This talk introduces SchedKit, a new open-source project leveraging the power of eBPF and the sched_ext framework. SchedKit allows users to leverage custom Linux...
"Public Money? Public Code!" (osc25)
‘Public Money? Public Code!’ under this slogan thousands of individuals and hundreds of organisations come together and advocate for Free and Open Source Software in public institutions. Together with over 230 organisations the Free Software Foundation Europe (FSFE) is calling for public institutions to publish publicly financed software under a Free and Open Source Software license - If it is public money, it should be public code! The long-term goal of the initiative is to recognise and reduce the software dependency and vendor lock-in of public administration and to make public administrations digitally independent...
A Community has to do what a Community has to do! (osc25)
When proprietary products are discontinued or bought up by competitors, your own (decision-making) freedom can quickly become precarious. A discontinued product forces you to migrate, incurs costs, and imposes unwelcome decisions. Not so with open source software: it offers me the freedom to develop the code further at any time, either on my own or with new partners, and to set up new support chains. The freedom not to have to migrate and the freedom not to have to work with an unpleasant service provider. Even drastic changes in product and business strategy can be...

Swift Deployment and Faster Releases (osc25)
This session explores the utilization of parallelism and rolling updates within Ansible playbooks to expedite deployment processes and facilitate faster releases. As organizations strive for agility and efficiency in their software delivery pipelines, optimizing deployment strategies becomes crucial. By leveraging Ansible's parallel execution capabilities and implementing rolling updates, teams can reduce deployment times and minimize downtime, thereby enhancing overall release velocity. This session provides insights into the benefits and techniques of employing parallelism and rolling updates in Ansible playbooks to achieve swift deployment and accelerate software releases.

From ALP to SLES16 (osc25)
Last three years I have talked at this conference about SUSE’s plans, the products to come, as well as the technology included.
As over the time the plans are adjusted, this session will summarise the state of the matters, SUSE's plan for upcoming product releases and, most importantly, what it means for openSUSE Leap and Micro.
