enabling users to programmatically extend almost any functionality of the operating system. eBPF is an event-driven architecture that runs specific programs when the kernel or an application passes a certain that the program always runs to completion (will not sit in a loop forever, holding up further processing). System calls Captain Tux soon heard of possible improvement options. eBee’s fellows were zealous installed and rewired a boosted antenna. eBPF enhances networking by enabling efficient packet processing and filtering in the kernel decoupled from hard- ware-specific details while integrating seamlessly
