A loadable Linux Kernel Module (LKM) that creates a file in /proc and provides read + write functionality.

using Raspberry Pi 4 Model B to build linux kernel（32 bit Arch）.

LinkQUIC is a novel framework capable of distinguishing QUIC from normal UDP streams in kernel space without kernel modification, decrypting QUIC payloads, or prior knowledge of QUIC protocol implementations in user space. This framework can identify QUIC in both endpoints and middleboxes.
