eBPF Trend Analysis
The evolution of eBPF (extended Berkeley Packet Filter) has been one of the most significant developments in Linux system observability and networking over the past decade. As we look at the landscape in early 2025, several key trends have emerged that showcase eBPF’s growing influence and future directions.
Persistent Memory in Linux Kexec
If you’ve been following the Linux kernel development community over the past few years, you might have noticed an interesting emerging trend in the field of memory persistence when using kexec to boot into a new kernel.
Two-Phase eBPF Program Signing
The Extended Berkeley Packet Filter (eBPF) has revolutionized how we extend and observe the Linux kernel. However, with great power comes great responsibility, and securing eBPF programs has been a persistent challenge in the Linux kernel community. Today, I want to share an innovative approach to eBPF program signing that addresses some fundamental challenges in this space.
