[CVE] Linux Dirty Pipe CVE-2022-0847 漏洞分析

Vscode沃日你🌵



### Macos+Vscode调试指北

---

最近在写OS 对于Vscode调试这件事真的是折腾死了 遇到的问题包括但不限于

> 1. I'm sorry, Dave, I can't do that.  Symbol format `elf32-i386' unknown

常出现在使用`brew`安装的gdb中 更新gdb版本即可解决 `brew upgrade gdb`

> 2. Debugger executable ‘/usr/local/bin/x86_64-elf-gdb‘ is not signed.

又是苹果的奇葩安全机制 根据帖子`https://www.jianshu.com/p/303bc5f53a52` 即可解决

> 3. 远程调试连接不上&&使用插件发现只能汇编调试 不能源码级调试

其实都是自己写的launch.json的锅 不需要使用任何插件 直接原版vscode即可调试

```json
{
  "configurations": [
    {
      "name": "(lldb) 启动",
      "type": "cppdbg",
      "request": "launch",
      "program": "${workspaceFolder}/BUILD/kernel.bin",
      "args": [],
      "stopAtEntry": false,
      "cwd": "${workspaceFolder}/src",
      "environment": [],
      "externalConsole": false,
      "MIMode": "gdb",
      "miDebuggerServerAddress": "10.211.55.14:1234"
    }
  ]
}
```
