Topic 1: The Pod Knows Where You're From – Preserving Source IP with Cilium and DSR
In this session, Marcel Gredler delves into maintaining original source IP addresses in Kubernetes pods using Cilium and Direct Server Return (DSR). By bypassing traditional load balancers for return traffic, DSR boosts bandwidth and performance, enabling efficient handling of high-throughput workloads like AI model inference and training in cloud-native setups.

Topic 2: Signing eBPF for Security (with Hornet LSM)
Julian Zhuang discusses enhancing eBPF program security via cryptographic signing integrated with the Hornet Linux Security Module (LSM). This approach verifies eBPF code integrity before kernel loading, reducing vulnerabilities in observability, networking, and security tools while ensuring safe deployment in production environments.
