基于ebpf实现容器网络中veth网络性能的优化

项目标题：基于ebpf实现容器网络中veth网络性能的优化
【项目难度】：进阶
【项目描述】：
1、veth pair是linux中提供的一种虚拟网络设备，veth总是成对出现，一个pair对中的veth就像一根网线的两端，数据从一个端点流进，就会从另一端流出，veth可以配置ip，实现不同netns间的通信；当前veth pair容器网络中常用的网络模型；通过将veth的一段挂到Pod内，另一端在node上，实现Pod与外部网络的互通；
2、Pod流量经过veth pair后存在一定的性能损耗（对比测试主机进程直接通信的性能损耗约40%），存在较大优化空间；本项目期望基于ebpf技术对veth的网络性能做优化；
【产出标准】：
1、基于ebpf实现veth网络性能优化，性能可达成主机进程直通的90%+；
2、项目代码合入openEuler社区仓库；
【技术要求】：
1、对容器网络有一定的了解，了解veth网络的工作原理；
2、了解ebpf的基本原理，可编写简单的ebpf程序；

Project title: Optimizing veth network performance in container networks based on ebpf
[Project Difficulty]: Advanced
[Project Description]:
1、The veth pair is a virtual network device provided by Linux. The veth pair always appears in pairs. The veth in a pair is like the two ends of a network cable. When data flows in from one end point, it flows out from the other end point. The veth can be configured with an IP address. Implements communication between different netns. Common network models in the current veth pair container network; A section of veth is mounted to a pod and the other end is on a node to implement communication between the pod and external networks.
2、Pod traffic has certain performance loss after passing through the veth pair. (Compared with the test host process direct communication performance loss of about 40%) There is a lot of room for optimization. This project aims to optimize the network performance of veth based on the EBPF technology.
[Output standard]:
1、Optimize the VETH network performance based on the EBPF. The performance can reach more than 90% of that of the host process passthrough.
2、The project code is incorporated into the openEuler community repository.
[Technical Requirements]:
1、Have a basic understanding of the container network and the working principle of the veth network.
2、Understand the basic principles of ebpf and write simple ebpf programs.
