- Berkeley Packet Filter - Wikipedia
The Berkeley Packet Filter (BPF; also BSD Packet Filter, classic BPF or cBPF) is a network tap and packet filter which permits computer network packets to be captured and filtered at the operating system level
- BPF Documentation — The Linux Kernel documentation
BPF Documentation¶ This directory contains documentation for the BPF (Berkeley Packet Filter) facility, with a focus on the extended BPF version (eBPF) This kernel side documentation is still work in progress
- Berkeley packet filters - IBM
Berkeley Packet Filters (BPF) provide a powerful tool for intrusion detection analysis Use BPF filtering to quickly reduce large packet captures to a reduced set of results by filtering based on a specific type of traffic Both admin and non-admin users can create BPF filters
- bpf(2) — Linux manual page - man7. org
Extended BPF Design Architecture eBPF maps are a generic data structure for storage of different data types Data types are generally treated as binary blobs, so a user just specifies the size of the key and the size of the value at map-creation time In other words, a key value for a given map can have an arbitrary structure
- Understanding of BPF - Unix Linux Stack Exchange
What is BPF? BPF (or more commonly, the extended version, eBPF) is a language that was originally used exclusively for filtering packets, but it is capable of quite a lot more
- How Does BPF Filter Work: A Beginners Guide
BPF filters are a powerful tool for network traffic monitoring and cybersecurity They allow network administrators to capture and analyze specific types of traffic and filter out unnecessary traffic, helping to improve network performance and security
- BPF | Berkeley Packet Filter explained - IONOS
The Berkeley Packet Filter (BPF) or Berkeley Filter is relevant for all Unix-like operating systems, such as Linux The main task of the special-purpose virtual machine, developed in 1992, is to filter data packets from networks and embed them in the kernel
- 1 BPF Instruction Set Architecture (ISA) - Kernel
eBPF, also commonly referred to as BPF, is a technology with origins in the Linux kernel that can run untrusted programs in a privileged context such as an operating system kernel This document specifies the BPF instruction set architecture (ISA)
