This talk provides a generic introduction to a set of modern Linux kernel technologies:\n\n* [eBPF](https://ebpf.io/what-is-ebpf/) (extended Berkeley Packet Filter) is a kind of virtual machine that runs sandboxed programs inside the Linux kernel.\n* [XDP](https://docs.cilium.io/en/latest/bpf/progtypes/#xdp) (eXpress Data Path) is a framework for eBPF that enables high-performance programmable packet processing in the Linux kernel\n* [AF_XDP](https://www.kernel.org/doc/html/next/networking/af_xdp.html) is an *address family* that is optimized for high-performance packet processing. It allows in-kernel XDP eBPF programs to efficiently pass packets to userspace via memory-mapped ring buffers.\n\nThe talk will provide a high-level overview. It should provide some basics before the other/later talks on bpftrace and eUPF.\nabout this event: https://pretalx.sysmocom.de/osmodevcon2024/talk/RBXC3V/
