C programming language examples

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

Key-value BLOB's storage which is implemented as Linux kernel module which is written in C++

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.
