Cloudflare 自己用 Rust 寫了一套相容 WireGuard 協定的軟體

Cloudflare 發現目前符合他們條件的 WireGuard 軟體效能不夠好,所以就用 Rust 寫了一套出來:「BoringTun, a userspace WireGuard implementation in Rust」,軟體在「BoringTun」這邊可以看到。

Cloudflare 的條件是 userspace 以及多平台,市面上有 wireguard-go 符合這兩個條件,但效能不太好,所以就下去寫了。

GitHub 的頁面上可以看出還在剛開始的階段,很多頁面都還只有個雛型... 等這幾天陸陸續續更新後再回來看好了。

在 Linux 下引用 Windows 的 DLL 檔

作者為了在 Linux 下進行安全分析而弄出來的計畫:「Porting Windows Dynamic Link Libraries to Linux」。

作者對 Windows 的架構有不少抱怨 XDDD

Distributed, scalable fuzzing on Windows can be challenging and inefficient. This is especially true for endpoint security products, which use complex interconnected components that span across kernel and user space. This often requires spinning up an entire virtualized Windows environment to fuzz them or collect coverage data.

This is less of a problem on Linux, and I've found that porting components of Windows Antivirus products to Linux is often possible. This allows me to run the code I’m testing in minimal containers with very little overhead, and easily scale up testing.

This is just personal opinion, but I also think Linux has better tools. ¯\_(ツ)_/¯

而這個專案跟 WineHQ 完整模擬不一樣,這只是給 Linux 下原生的程式使用 Windows 下 DLL 內的功能:

This project does not replace Wine or Winelib.

Winelib is used to port Windows C++ projects to Linux, and Wine is intended to run full Windows applications. This project is intended to allow native Linux code to load simple Windows DLLs.

The closest analogy would be ndiswrapper but for userspace.

作者拿了 Windows Defender 當範例,示範在 Linux 下呼叫 Windows 的 DLL...
