WSL2 内部实现探究

背景

最近看到 Windows Subsystem for Linux September 2023 update 声称 WSL2 最新的预览版本支持让 Linux 和 Windows 一定程度上共享网络地址空间，就像 WSL1 那样：

● IPv6 support
● Connect to Windows servers from within Linux using the localhost address 127.0.0.1
● Connect to WSL directly from your local area network (LAN)
● Improved networking compatibility for VPNs
● Multicast support

因此比较想知道这是怎么做到的，但目前我手上还没有预览版本的 windows，因此目前先研究 WSL2 已有的功能是如何实现的，未来再回来更新这一部分。
