Why the swipe at Linus? He’s been supportive of rust in the Linux kernel.
There’s no shortage of reasons to not like Linus.
Did… Did you just diss the All Mighty Father, Emperor of Linux on Lemmy?
He did! He did just diss the All Might Father, Emperor of Linux on Lemmy!
Unacceptable! Go get the SIGKILL
kill -9You gotta learn when it’s time for your thread to yield; you shoulda slept; instead you stepped and now your fate is sealed.
Maybe read the article…
I did - it says he’s supporting rust in the kernel.
I do know that Linus is on record with low opinion of C++. I have heard of him compare the cult-like following Rust has with the whole Vim/Emacs tribalism thing.
I didn’t understand this. He said the bickering between C and rust devs reminds him of the vim/emacs debate.
I have heard of him compare the cult-like following Rust has with the whole Vim/Emacs tribalism thing.
Heh.
I do think the worst thing going for Rust, right now, is the Rust community.
It feels like few specific jackasses from the Java community made the jump to Rust, and no one had the sense to slap them with a newspaper.
Can you be more specific? I’ve had nothing but great experiences from the rust community.
Can you be more specific?
Sure.
I’ve had discussions about my impression that Rust’s build chain can be a bit surly compared to other popular languages.
I don’t particularly mean it as a criticism - of course Rust’s security enforcement comes with more warnings and errors.
But the novel part of the interactions, for me, was Rust community members coming at me with ‘well get gud, newbie’.
These interactions are particularly ironic, given my experiences and specialties. I’m an old school veteran software developer. I have spent over half of my career in dedicated Cybersecurity roles.
These conversations converted me from a mildly interested Rust proponent into a casual Rust critic.
Well I’m sorry that you got shitty responses like that. Which platform(s) was this on?
Java sucked so much though (and still does).
I love programming in Java. It continues to be my language of choice.
they don’t swipe him at all. I don’t know why his picture is there
because that makes people click
Too bad! Stay in your lane, pinche government!
yeah No.
Well now I’m going to have to use it even more.
I don’t get why we’re taking a swing at Linus here. The article only mentions him in relation to the rust for Linux project being slow going. But, it IS going and the US government has only stated that “you need a plan to move to a memory safe language by 2025 or you might be liable if something bad happens as a result of the classics (use after free/double free/buffer overflow/etc.)” but I don’t think Linux would count it’s free software and it does have a plan.
Ok, and what do you think the memory managers were written in?
Don’t worry bud, I’ll upvote you. Not everyone is afraid of pointers.
AFAIK, the first one was written in LISP.
The one most people push around here was written in Rust. It’s a really great language to write memory managers anyway.
If it’s broke, don’t fix it amiright?!
Who cares? Just like most things your average programmer relies on, they are written by smarter or at least more specialised people to make your job easier. They have learned to write memory-safe code so you don’t have to.
More specialized is critical.
You have to understand your domain, what your goal is, how much time and money you have, etc.
God, this old argument… Careful, it’s an antique.
The idea is to minimize memory management and have people who are experts on it deal with it.
I don’t think those are the problem, but rather how they are used. And in case of managed languages like C#, it’s almost impossible to shoot yourself in the foot when it comes to memory management. You still can, if you really wish, but you have to be very explicit in that. 🤷♂️
But there is context to it:
The report on Product Security Bad Practices warns software manufacturers about developing “new product lines for use in **service of critical infrastructure or [national critical functions] **NCFs in a memory-unsafe language (eg, C or C++) where there are readily available alternative memory-safe languages that could be used is dangerous and significantly elevates risk to national security, national economic security, and national public health and safety.”
It’s for new products that are very important to critical infrastructure and need to be safe as possible. The article writer seem not to be aware of this context:
Take Rust in Linux, for example. Even with support from Linux’s creator, Linus Torvalds, Rust is moving into Linux at a snail’s pace.
Because Linux is the biggest software in the entire world and they do lot of stuff their own way. Rust is integrated slowly for future new projects. It makes sense to move in snail pace. The government doesn’t suggest the Linux project to stop using C entirely. The government “recommends” to start new projects in memory safe languages, if it is a critical software. That makes sense to me.
You see, people who’ve spent years and sometimes decades mastering C don’t want to master the very different Rust. They don’t see the point.
No, totally wrong. C programmers in Linux do not NEED to learn or master Rust. They just need to cooperate. The problem is, that some C programmers refuse to cooperate with Rust. They just want Rust to disappear. That has nothing to do with mastering the language. They refuse to make changes to their C code, so it can cooperate with Rust code via bindings.
After all, they can write memory-safe code in C, so why can’t you?
Nonsense argument, and false too. If that was the case, why do we have memory safe languages? Clearly people make mistake, old and new. Besides Linux is not the only software in the world.
Converting existing large codebases to memory-safe languages can be an enormous undertaking.
Nobody says old code should be rewritten in Rust. Neither the government, nor the Rust programmers in Linux suggest that. It’s not about rewriting code in memory-safe languages, its about new projects.
Either this article is a misrepresentation or misunderstanding. Or I misunderstand the article or government. I don’t know anymore…

Doubly so… Don’t care what the language is, or what the advantages are… Even if there’s a considerable security advantage to a new language… There’s no such thing as a language that’s advantages outweigh the security risks of rushed development to convert decades of tested code.

I would argue that’s not the biggest problem, the biggest problem is that for you to refactor a function to work with rust, you need to refactor all the subsystems that rely on that function, and that take time, and you need to explain for the C dev why it need to be done, try to explain that for the amount of C devs in the kernel
They refuse to make changes to their C code, so it can cooperate with Rust code via bindings.
I don’t even think the rust devs where asking for that. They are refusing changes by rust devs that help with rust while making the c code clearer and even refuse to answer questions about the semantics behind the c code. At least as far as I can see from the outside.
The Rust kernel devs are …
- …asking the maintainers to lock down APIs which the C devs purposefully leave malleable, in part, to avoid binary blob drivers being feasible.
- …asking maintainers to accept code into their subsystem whilst being told, you don’t need to know Rust to an expert level…trust us. Cross language interfaces always have nuance and make good attack vectors. Understandable that maintainers are cautious.
- …creating quite a lot of hassle for no a lot of improvement. Systems are only as resilient as their weakest components. The cross language interface is always going to be weak. Introducing a weakness to get improvements probably only succeeds at making the whole weaker.
What’s the reason to avoid binary blob drivers being feasible? Is that about not being able to use non-free binary blobs in kernel? I don’t quite understand what it even is about
Having binary blobs linked into your kernel is a maintainability nightmare. You’re allowing a third party to link their buggy drivers into the heart of your platform. It breaks any security model you have, and brings with a bunch of bugs that are impossible to debug.
Nvidia were the worst offender and it culminated in this:
https://arstechnica.com/information-technology/2012/06/linus-torvalds-says-f-k-you-to-nvidia/
Got it. I agree that their drivers are (were?) of exemplary bad quality
But I don’t think that it is realistically possible to drop all the proprietary firmware blobs, and if it’s not maybe it’s better to not actively sabotage something to ‘avoid those being feasible’?
Firmware don’t link to the kernel tho, and the kernel functions aren’t stable so a firmware today would stop working tomorrow because a function was refactored(and all the code in the kernel that depend on that function) for performance or security, and the binary can’t be refactored so it become useless
asking the maintainers to lock down APIs which the C devs purposefully leave malleable, in part, to avoid binary blob drivers being feasible.
No, they were asking them to define the semantics of the filesystem APIs. Those semantics are not encoded in the C API but the Rust devs wanted to encode them in the Rust API to avoid making mistakes.
The C devs didn’t want to, not because of concerns about binary drivers, but because the semantics are already broken. Apparently different filesystem drivers assume different semantics for the same functions and it’s a whole mess. They don’t want to face up to this and certainly don’t want anyone pointing it out, so clearly it must be the Rust devs’ fault for wanting APIs to have consistent semantics.
The rest of your comment is nonsense.
IIRC They were also trying to get kernel devs to let official structure definitions live in Rust instead of C, and got upset when they didn’t want to do that.
the rust devs wanted to CREATE official structure definitions that don’t exist in C so that there was more semantic meaning to the APIs
To address this concern, CISA recommends that developers transition to memory-safe programming languages such as Rust, Java, C#, Go, Python, and Swift.
If only it were that easy to snap your fingers and magically transform your code base from C to Rust.
guy_butterfly_meme.jpg is this unbiased journalism?
As the article is denoted as a comment, it is not its aim to be unbiased journalism.
I don’t know why you’re being downvoted. It literally starts with the word OPINION in bold red caps.
My mind was making one transfer to much, as the opinion clip in German TV news is called comment. There were no additional downvotes after I added the second sentence for clarification.
The comment thread in that article is interesting. Grep for Ada.
The US government hates anything that can perform math too fast.
As someone who learned Ada for a defense job years ago, I’ve been wondering how long it was going to take until I saw others comparing Rust to it, both in the sense of the language “safety” goals and the USG pushing for it.
While the rust compiler is leagues better than any Ada compiler I ever had the misfortune of dealing with, the day to day pain that Rust incurs will probably always be a thorn in it’s side
well, i’m glad the US government is at least aware what C and C++ are!
If only it were that easy to snap your fingers and magically transform your code base from C to Rust. Spoiler alert: It’s not.
How utterly disingenuous. That’s not what the CISA recommendation says, at all.
The US government has more pressing issues I think.
Maybe it can shut the fuck up an let me do my job in contrast to its judicial branch.
What if I told you the judicial branch is doing its job because it was always evil to begin with?
I would say you’re right
Because they want to replace them with more corporate-controlled languages.
Just add
@safe:after yourmoduledeclaration, and you’ll be safe by default if you don’t want to wait until D3.Also, unlike in Rust, you can opt-out from RAII with
int foo = void;, although it primarily has a performance advantage with arrays, not singleton variables (might be also useful for aquiring an RNG seed in a dumb way).Jep, you got em, it’s all a conspiracy so they poison our mind with the evil tongues and make us corpo slaves with the help of Rust.
