eBPF, or Extended Berkeley Packet Filter, is a kernel technology available since Linux 4.4. It lets developers run programs without adding additional modules or modifying the kernel source code. Think of it as a lightweight, sandboxed virtual machine (VM) within the Linux kernel that lets you run Berkeley Packet Filter (BPF) bytecode that uses certain kernel resources. Utilizing eBPF removes the need to modify the kernel source code and improves the software’s capacity to use existing layers.
