Yet Another Recorder(yarc)

Yarc is a traffic recording tool based on ebpf. It records real online traffic and uses the traffic playback tool for testing. Yarc attaches the program used to hook the socket system function to the kernel system function through bpf, and transfers the recorded data to the user space with the help of BPF_MAP to achieve recording.
