kpatch是一种在Linux操作系统上用于动态修补运行中的内核的工具。它的主要目的是允许系统管理员在不需要重启整个系统或者停止任何正在运行的进程的情况下,应用关键的安全性补丁和其他更新。这种技术在确保系统稳定性和性能的同时,提高了系统的安全性。详细说明如下:1.实时内核修补概念:Linux内核是操作系统的核心部分,负责管理系统资源和硬件设备。传统的做法是,每当需要打补丁或更新内核时,系统管理员必须重启系统以让更改生效。kpatch技术改变了这一做法,它允许内核在运行时更...

但是这份源码体积很大,并且还需要FQ,所以多年前就有好心人把quic源码剥离出来单独放github了,在文章末尾的参考2处;1、quic相比tcp实现的tls,前面省略了3~4个RTT,根因就是发起连接请求时就发送自己的公钥给对方,让对方利用自己的公钥计算后续对称加密的key,这就是所谓的handshake;在libquic-master\src\net\quic\core\quic_crypto_client_stream.cc中有具...
