provides an interface for applications to interact with the underlying hardware). The kernel has visibility across the entire system and is highly performant, but needs to provide a stable interface to applications tracing programs almost anywhere in kernel or user applications. eBPF is a strictly-typed assembly language with a stable instruction set. eBPF programs can be loaded and upgraded in real time without the
