Add a per-flow rate limit, limiting how often new timestamp entries can be created. As part of this, add per-flow state keeping track of when last timestamp was created and last seen identifier for each flow. Additionally, remove timestamp entry as soon as RTT is calculated, as last seen identifier is used to find first unique value instead. Furthermore, remove packet_timestamp struct and only use __u64 as timestamp, as used memeber is no longer needed. This initial commit lacks cleanup of flow-state, user-configuration of rate limit, mechanism to handle bursts etc. Signed-off-by: Simon Sundberg <simon.sundberg@kau.se>
Practical BPF examples
This git repository contains a diverse set of practical BPF examples that solve (or demonstrate) a specific use-case using BPF.
It is meant to ease doing rapid prototyping and development, writing C-code BPF programs using libbpf. The goal is to make is easier for developers to get started coding.
Many developers struggle to get a working BPF build environment. The repo enviroment makes it easy to build/compile BPF programs by doing the necessary libbpf setup transparently and detect missing compile dependencies (via the (configure)[configure] script). It is a declared goal to make BPF programming more consumable by detecting and reporting issues (when possible).
