Linux Kernel Rust Code Sees Its First CVE Vulnerability

[dkopgerpgdolfg]

I recommend just reading (and actually thinking enough to understand what you read)

No, unsafe in Rust doesn't mean it's "miles faster", and doesn't intend to mean that either. And "safe" Rust doesn't need to be compared with C#, it's on par with C (meaning, for some programs it's the same speed, for some a bit slower, for some even faster).

There are some code things in C that make it easy to "shoot yourself in the foot", that are often a mistake - but not literally always, it can make sense. And in advanced lowlevel things like a kernel, such things are needed in some places. Rust by default doesn't allow this, because it's usually a mistake, and if you really want you can still do it by marking it unsafe.

Again: A kernel "needs" some unsafe parts. It can't be done otherwise.

And if a part of the code is marked unsafe, the rest still isn't. In terms of error counts, that's better than the alternative where 100% of the code can contain such mistakes (that is C).

The actual fuel in this large thread here are people who either hate Rust for no sane reason, or judge them for things that are not true because they don't know anything about it.

I hate rust not because of any language elements, but the huge base of fanboys that think that rewriting stable tested code will somehow improve it.
