WEBNov 10, 2022 · BPF defines a type of packet filter, implemented as a virtual machine, that can run in the Linux kernel. Before BPF, packet filters ran only in user space, which was much more CPU-intensive than kernel-level filtering. BPF has typically been used for programs that need to capture and analyze packets efficiently.
