BPF is Eating the World, Don't You See?

Explore the expanding role of BPF (Berkeley Packet Filter) in the Linux kernel through this conference talk from the Linux Plumbers Conference. Dive into how BPF's versatile virtual machine is revolutionizing kernel operations by offering a powerful combination of flexibility and performance. Learn about the challenges this creates for developers, system administrators, and support engineers, and discover the recent improvements in tools like perf and bpftool for observing and managing BPF programs. Understand the current limitations in profiling JITed BPF programs and the ongoing efforts to enhance debugging capabilities. Gain insights into future development areas, including probe placement, variable content collection, and BTF (BPF Type Format) utilization for improved annotation. Join speaker Arnaldo Carvalho de Melo from Red Hat Inc. as he discusses these advancements and seeks feedback for further enhancing BPF support in the Linux ecosystem.
