Open Source Summit North America 2025

Debugging Linux kernel crashes is a fundamental skill for developers working in kernel development. In this session, we’ll dive into four of the most common crash types—null pointer dereference, stack overflow, use-after-free, and divide-by-zero. Using real-world examples from an Azure Linux VM, we’ll analyze dmesg logs, walk through kernel crash reports, and demonstrate how to effectively debug these issues using tools like gdb and KASAN.
Beyond debugging, we’ll explore the performance impact of kernel configurations. Specifically, we’ll examine how kernel command-line parameters influence performance, using the SRSO mitigation as a case study. This session will provide practical insights into debugging crashes and optimizing kernel performance, helping developers strike a balance between stability, security, and efficiency in real-world deployments.

Linux is widely regarded as being a strong choice for those who value a secure operating system, but what is it about Linux that earns it this reputation? In addition, while it may be more secure than alternatives, it is by no means impenetrable. What are the weaknesses in a Linux system and how are they commonly exploited by malicious actors? More importantly, what can be done by administrators to ensure that their system is as secure as possible? We will use an example of somebody setting up an Ubuntu web server as a starting point and discuss ways in which the web server can be hardened. We will highlight the importance of implementing best security practices such as using Linux Security Modules, configuring firewalls, and more. As we discuss these best practices, we will demonstrate ways in which failing to use them can leave the web server vulnerable to malicious actors. Ultimately, the audience will leave the talk with an understanding of how Linux systems are vulnerable to attacks, what can be done to harden a Linux system, and how implementing some of these best practices can prevent attacks.

This session provides a comprehensive overview of essential Linux networking concepts, from IP addressing and routing to practical troubleshooting techniques. Participants will learn to configure network interfaces, diagnose common network issues, and gain the confidence to manage Linux network environments effectively.

When you are running an application that contains primary ingredients such as Java, MySQL, Mail Service etc. and all fused up together to be as one, then it is no surprise that you need to rely on more than one monitoring solution. But imagine if there is a one single solution that can bring up the Logs, Metrics, Traces and even Profiling and on top of that, it is completely Open Source? Well, you are in luck, as in this talk we will demonstrate an example on how to monitor your applications by using Grafana and use various integrations and plugins. Later, we will see more advanced features to get key metrics for better observability.

It will be an introduction to the Dashboards, and also an excellent opportunity to learn more about the advanced features, including troubleshooting & debugging.

Join us to learn more about Grafana dashboards, community contributions and share your feedback and suggestions!
