From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

One Of The Rust Linux Kernel Maintainers Steps Down - Cites "Nontechnical Nonsense" (www.phoronix.com)

Wedson Almeida Filho is a Microsoft engineer who has been prolific in his contributions to the Rust for the Linux kernel code over the past several years. Wedson has worked on many Rust Linux kernel features and even did a experimental EXT2 file-system driver port to Rust. But he's had enough and is now stepping away from the Rust for Linux efforts.

From Wedon's post on the kernel mailing list:

I am retiring from the project. After almost 4 years, I find myself lacking the energy and enthusiasm I once had to respond to some of the nontechnical nonsense, so it's best to leave it up to those who still have it in them.

...

I truly believe the future of kernels is with memory-safe languages. I am no visionary but if Linux doesn't internalize this, I'm afraid some other kernel will do to it what it did to Unix.

Lastly, I'll leave a small, 3min 30s, sample for context here: https://youtu.be/WiPp9YEBV0Q?t=1529 -- and to reiterate, no one is trying force anyone else to learn Rust nor prevent refactorings of C code."

It’s Ted Ts’o, the maintainer of the ext4 filesystem amongst other things.

little shit

Though you’re still accurate despite his seniority.

There's really only one valid response to Ted Ts'o:

If you think you can do better with C, prove it.

You seem really invested in pointing out those shortcomings. I respect that.

Arrogant hypocrites are a pet peeve of mine. If someone is going to act like progressive technology changes are beneath them and unnecessary, they should be able to put their money where their mouth is.

Somebody needs to send a public email to the kernel mailing lists with this

How many vulnerabilities have the kernel Rust team introduced in the same time period on the same code?

[–] pivot_root@lemmy.world 8 points 2 months ago (1 children)

Let me know when you find one?

[–] wewbull@feddit.uk 4 points 2 months ago (1 children)

Memory ownership isn't the only source of vulnerabilities. It's a big issue, sure, but don't think rust code is invulnerable.

[–] pivot_root@lemmy.world 5 points 2 months ago* (last edited 2 months ago) (1 children)

Of course. Rust isn't immune to logic errors, off-by-one mistakes, and other such issues. Nor is it memory safe in unsafe blocks.

Just by virtue of how memory safety issues account for 50%+ of vulnerabilities, it's worth genuinely considering as long as the bindings don't cause maintainability issues.

[–] WarmApplePieShrek@lemmy.dbzer0.com 2 points 2 months ago

The bindings cause maintainability issues. That's the problem.
