Speakeasy Productions has filmed and published a documentary titled "eBPF: Unlocking the Kernel," which narrates the story of the creation of the eBPF subsystem in the Linux kernel. eBPF provides a kernel-integrated bytecode interpreter with JIT, enabling the runtime modification of system behavior through user-space loadable handlers without the need to alter the kernel code, allowing the addition of efficient handlers without complicating the system itself. Among other things, eBPF can be used to create network operation handlers, manage bandwidth, control access, monitor system performance, and perform tracing.
