Reporting bugs before Ubuntu releases has never worked for me. They always land a bunch of major changes after the supposed "freeze" then they ignore all feedback because of the freeze. It's infuriating.
I've been a Ubuntu user for about 20 years, and I file bugs every now and then on launchpad. I don't recall any of them ever being fixed.
Maybe the bugs get traction if you have a service contract?
Best to file bugs directly to upstream, but that of course means you should try it on the latest upstream version and not whatever version ubuntu ships, so it's more friction.
I think ubuntu wants to kill desktop linux. No other explaination of why they push firefox inside snap, which then proceeds to constantly crash, when firefox used normally works completely fine.
I haven't tried chromium but I presume it's the same issue.
At work I'm forced to use ubuntu and I placed snapd on hold and added mozilla's own apt repository to my configuration to get firefox.
At least in the past few months the dbus crashes (been using systemd on debian for several years just fine, this never happened) that render the system unusable and un-rebootable have stopped… I guess when my company will decide to upgrade to 26.04 there will be more instability and problems.
Appimages are bloated and unreliable. You can't guarantee that your app will run on any machine because it might depend on different system libraries.
Flatpak uses shared stable runtimes that are the same everywhere and don't take up space more than once. It also comes with a native update system and sandboxing. Snap is the same thing but worse.
yeah, this is a bug. And yes, it should be fixed. But I don't think it will affect many users, I mean who has a 32000 -evels deep directory on their system?
It's a stack overflow which means it's using recursion and for historical reasons that don't make sense any more, stacks are teeny tiny on 64-bit Linux - apparently only 8 MB on Linux! I'm not sure why they don't raise it to something reasonable like 4 GB. I guess because they want consistency with 32-bit? Maybe we can finally change it if/when they phase out support for 32-bit Linux. Apparently it might not be that far away:
8MB is the default per-thread stack size from glibc, also seems to be the default "ulimit" from pam or the kernel, I'm not sure. So for the main/default thread (or if not using threads) the process can use setrlimit() and for threads it can use pthread_attr_setstacksize() to get bigger stacks if it knows it may need them.
8MB is pretty huge though; musl libc is famous for defaulting to much smaller per-thread stack size of 128KB (to avoid over-committing lots of memory when there are many threads - the main dev is really principled/opinionated on this topic, but again there are a few ways for applications to explicitly size their stacks as large as they need). Linux kernel threads get a bit less than 16KB!
For what it's worth there's reasonably active [1] work on implementing opt-in guaranteed tail calls - but it's not particularly fast going. LLVM (the backend rust uses) needs better support for musttail (e.g. some architectures just don't support it [2]).
By-default guaranteed tail calls really isn't rust's style, because it means subtle changes (introducing a destructor, re-ordering code, etc) can change semantics without you realizing it. If you want to guarantee that a call can't allocate a new stack frame you should have to say it.
Not so familiar with this area, but isn't the existing behavior of implicitly creating new stacks more of a problem than implicit tail-call elimination? Seems the latter is a kind of compiler-level optimization, of which there are already many (I think) that change the semantics internally but guarantee the outward behavior stays the same.
But I can understand the preference for an explicit opt-in, to make clear that it is enforced and not assumed.
I'd argue that it's explicit - that's what a function call does and you don't have implicit function calls in rust.
> Seems the latter is a kind of compiler-level optimization, of which there are already many (I think) that change the semantics internally but guarantee the outward behavior stays the same.
What you're asking for here already exists. Tail calls might be optimized into not allocating extra stack frames, the rust compiler just doesn't guarantee that it will perform that optimization (and almost certainly won't when code is compiled without optimizations... for instance).
What people want is the semantic guarantee that the stack frame won't be allocated. Not just a compiler that often performs the optimization. Otherwise you can't be sure that your code will keep working with new compiler flags/versions/architectures/... You could say "whenever the code is the right shape we'll guarantee the optimization" (C++ famously did this for things like copy elision)... but now the shape of code comes with non-obvious semantic guarantees and that's not rust's style. Hence the proposal for a keyword instead.
I see it, certain algorithms need guaranteed tail-call elimination, otherwise they are too inefficient and must be manually unrolled or rewritten to avoid blowing the stack. So a compiler optimization that is "nice to have" is not good enough.
> because it means subtle changes (introducing a destructor, re-ordering code, etc) can change semantics without you realizing it.
No, it won't change semantics - if you say @musttail or similar, it will simply fail to compile if you, say, introduce a destructor - the semantics will not subtly change.
Uh, yes, if you guarantee the semantics only when the code explicitly opts in and not by default then semantics will not subtly change, that is the point of my comment
The point is that such bugs shouldn't exist in the first place.
Using recursion on unbounded inputs on a programming language that doesn't support that (which are most) is an extremely classical mistake that really should be known to all programmers, especially those of low level languages that care about safety.
Every time you call something recursively you should be thinking "how deep is this?".
The problem there is that this is exactly the class of bug that does not exist in GNU coreutils because of philosophy of that project. Non-existence of such bugs proves that the impementation is not copied from AT&T code.
Nah, people should (and do) fix small issues as well as big issues. Lying about the scale of issues and calling them "big" when they aren't just leads to no ability to prioritize or evaluate.
Incidentally someone submitted a PR for this issue about 3 hours before the first comment about it in this thread - https://github.com/uutils/coreutils/pull/14554 (and 2 hours before this link was submitted to HN)
This isn't a port - it's a re-implementation without any use of the original source.
That's also not all that's happening. It's also making improvements like better internalization support, better error messages, and a small handful of other extensions.
I have had to tell them repeatedly to stop copying tests verbatim, including the original comments from GNU coreutils. So I doubt this is true, which is frustrating.
Wow! Memory safety and such... Reminds me when a friend of mine wrote in IRC long time ago: "Hmm, tail just segfaulted." When I asked "Are you on Hurd?" he just replied "Yes."
You can use coreutils-from-gnu instead uutils. However since 26.04 build-essential depends on coreutils-from-uutils, it cannot be upgraded while coreutils-from-gnu is installed.
But it's clear that Ubuntu will remove coreutils, genuine sudo and other tools from the future versions. It's the direction, it's ideological and thus nor merit nor our feedback will change anything here.
You can use equivs to create a dummy coreutils-from-uutils package, as mentioned in the responses to that report.
It is frustrating that Canonical has no interest in fixing it, though. It makes it hard to take their claims seriously that you can still use GNU coreutils if you want.
So what is the way forward for Linux to have sandboxi g as strong as Android? Appimage everything? I know it's possible now hacking together things, but I mean by default and integrated.
Has the code quality in that repo gotten to a good point then? I haven't followed it much, but last I looked[1] (which was a few years ago) almost every tool I looked at in detail had pretty bad performance or correctness issues.
I’m a huge proponent of Rust and generally lean a lot closer to the RIIR mentality than most, but this effort seems to be such a waste of effort and resources.
There have been a dozen CVEs reported against all of coreutils in the past twenty years. The most recent audit of uutils-coreutils turned up forty-four CVEs.
By all appearances they’re replacing battle-tested and fundamental tooling which hasn’t been a problem with extremely amateurish Rust. The threading highlighted in the linked post above seems pretty egregious.
Neither. They basically see Rust as the future. They want to be able to attract young contributors and to hire young employees who are excited about Rust and who want the safety features. Bear in mind, the average age of the Linux developer is increasing. They also see technical benefits in Rust. And they are increasing test coverage of both the Rust tools and the tools written in C, IIRC.
There is a reason all FOSS OS alternatives for embedded systems like Zephyr, NuttX, FreeRTOS, IDF, Arduino,... are not GPL based, while Google has purged Android and ChromeOS from it, the the Linux kernel being the only GPL piece left.
Hmm, this doesn’t make sense. You simply don’t replace utilities with many decades of maturity and that “just work” with something that is not as mature. It will open all users of the distro to all sorts of subtle and not so subtle bugs. I for one don’t want to find myself staring at a mysterious segfault when I want to build the latest version of nodejs or flash a microcontroller. It’s such a pity; I have used Ubuntu for close to 23 years.
i mean, i use ubuntu on multiple personal devices that i use daily and like <1% of the packages installed are managed with snap, and to me, it isn't as bad as everyone makes it out to be.
the point i was trying to make was that it is much harder to replace things like .net / powershell in windows for simple cli workflows.
in linux, you can just drop the executable you want to use in your path. so, gnu coreutils will build on pretty much anything you need them to, and are very stable. it is <5m of effort to build it and swap the executable / lib in your path.
also, as mentioned here, ubuntu will allow you to select which package you want to install from the normal repos, so you don't even need to do that.
Ubuntu started out with a slogan claiming "linux for human beings", and it kept that reputation for well over a decade, with a heavy focus on the desktop.
You can split hairs however you want, but this created a legacy, and is why Ubuntu is still one of the top recommended distributions for beginners.
FWIW, Canonical did not reach out to any of us who maintain GNU coreutils before, after, or during the transition. Had we known, we could have easily warned them about the incompatibilities.
> Ubuntu devs have been nothing but good FOSS citizens
They have forced systemd despite feedback and genuine concerns.
They have forced fake sudo and uutils the same way.
So, ideology over merit. That doesn't mean that all of the Ubuntu devs are this way, but this means that the company is consistent in its ways to hurt Linux.
I does. The OP says "Linux" but means "Linux distros", which are made of thousands of "commingled" pieces (i.e. the licence of one piece does not affect the other).
Each piece that becomes MIT means less pressure on corporate users to give back any changes they make, and we'll end back up in the 1980s again where "Amazon Linux" is full of secret-sauce they refuse to publish and makes the base system incompatible with "Google Linux" (or whatever happens to be kicking about), creating deliberate lock-in out of a system that started open. In much the same way that macOS and FreeBSD are divergent today.
In theory there could be a the MIT version relicensed to GPL and this version could be carried as a standard if having MIT software as core utilities was considered enough of a threat - right? You just have to retain original license/attribution.
That would be an awfully awkward move in the realm of Linux-related politics but if having an MIT-licensed coreutils was such an existential thread, at least you can fix it with aggressive license moves and not code.
We've balkanized Linux but you're free to use the original (which we are deliberately incompatible with, as is rival #2, rival #3, rival #4, etc. and we're all mutually incompatible with each other)
Amazon and other clouds already patch the hell out of Linux, but they don't distribute physical devices with that Linux on it to anyone, so they don't have to deliver source code either.
I am not totally sure I see the actual concern here, that a company is going to sell devices with a really great `find` implementation but not contribute it upstream?
In the 1980s and 1990s, there were a number of commercial Unices (SunOS, HP-UX, AIX, IRIX, etc.) Every one of them was incompatible with each other, sometimes subtly, sometimes blatantly. They were all competing against each other and all seemed to encourage you to use their proprietary extensions in your software and deliberately fuck over anyone using any other variants.
What it meant was a headache for writing platform-agnostic software. It was not a productive way to create software.
Replacing GPL software with MIT software just encourages this behaviour to come back. We already see it with how macOS userland took FreeBSD and sprinkled incompatibilities everywhere.
“Concerning” is just a right wing thing to say. They get the habit from Musk. They say it and don’t elaborate, so it kinda operates like a dog whistle.
Great "elaboration" (actually it's an "example"), indeed pulling everything into the political dimension is one of the concerning things regarding anything Linux nowadays, imho. Next up: DHH!
BSD is the future. Wishful thinking. Nothing bad about it, but chances are low.
Ss for AI slop. There is lots, but I do not think Linus will tolerate a heavy quality degradation and policies will be set up to strike a good balance.
X11 and everything around it is unfixable security hazard slop, just slop that was painstakingly created by humans.
Also Wayland is it being forced on us? I have plenty of coworkers that run X daily because they are still afraid of the Wayland boogeyman despite the fact that their supposed clipboard and screen sharing problems in Wayland (the only two supposed problems they can name) have been solved for years.
There have been twelve CVEs reported against coreutils in the past twenty years.
There were forty-four against this project in just the last audit.
I am all for RIIR in cases where it makes sense. This does not even remotely appear to be one of them. By all appearances the quality of the code is extremely amateurish at best. coreutils has not been a significant source of vulnerabilities in the past, and they’re replacing it with code written by amateurs that performs worse and already has a worse security track record.
It really does matter. I don't know enough about this specific case, but multiple order of magnitude differences in CVE numbers are frequently explained by different policies towards finding and assigning CVEs in many many cases.
Absent more information the default should be to hand wave it away as probably such a difference. CVE counts are not a even slightly reliable metric.
Most of them are TOCTOU races or improperly following symbolic links. For example, uutils mkfifo(1) would create a world-readable and writable FIFO before using chmod(2) to restrict its permissions. Another user could replace that file with a symbolic link between the mkfifo(3) call and the chmod(2) to change the permissions of arbitrary files [1].
Other ones I find concerning are that you could also bypass '-- no-preserve-root' with a symbolic link to root [2]. Or by using paths equivalent to "/", e.g., "/../" [3]. Historically, GNU coreutils has been pretty good with symbolic links and avoiding TOCTOU races. The only notable one I can remember is a chmod(1) bug [4].
I agree with your general point that the number of CVEs is a useless metric, though.
I really don't understand why Canonical rushes this. If 'rm' can't remove all possible directory entries, that is a big issue:
Rush? This is an interim release (95% or so only tracks LTS's) that is not even out yet... Go file a bug reports if you have some time.
I did, and the original dev of the component fixed it within a few days. It was straightforward, a backwards reading of a spec, reordered.
The fix is still sitting unmerged many months later.
This surprised me since I thought the project was in heavy bugfix/compat mode. I won’t touch it until I see some velocity on open bugs.
Fork Ubuntu and threaten their business model, that’ll get their attention.
Only half joking.
I have. It has been an open bug upstream for years as well.
ok, that's concerning, if you post it here I'll vote for it (after confirming).
My experience is that filing bug reports to ubuntu is a complete waste of time. Not sure if it's different for paying users.
Reporting bugs before Ubuntu releases has never worked for me. They always land a bunch of major changes after the supposed "freeze" then they ignore all feedback because of the freeze. It's infuriating.
Glad to hear that I am not alone. I feel like launchpad is totally ignored most of the time.
To get a response on a buggy GNU coreutils patch of theirs [1], I had to mention it in a rust-coreutils bug months later...

Let them first fix Snap.
There is no reason for anyone on any distro to use snap.
It will die so just leave it alone.

Yes, please. Linux distros is better with macos approach. And making appimage first class makes a lot of sense.
Appimages are bloated and unreliable. You can't guarantee that your app will run on any machine because it might depend on different system libraries.
Flatpak uses shared stable runtimes that are the same everywhere and don't take up space more than once. It also comes with a native update system and sandboxing. Snap is the same thing but worse.
I'll avoid it at this point anyway. The Rust coreutils is another reason for that. Snap, monetizing updates, telemetry, enough is enough.
Yup. After almost 20 years, I have had enough of their crap. All of my new machines are getting Debian. Can’t wait until I am free of Ubuntu.
yeah, this is a bug. And yes, it should be fixed. But I don't think it will affect many users, I mean who has a 32000 -evels deep directory on their system?
What programmer or programming language can't iterate a loop more than 32000 times?!

No algorithm requires tail-call elimination in a general-purpose language with imperative mutability. It's just another way to express iteration.
> because it means subtle changes (introducing a destructor, re-ordering code, etc) can change semantics without you realizing it.
No, it won't change semantics - if you say @musttail or similar, it will simply fail to compile if you, say, introduce a destructor - the semantics will not subtly change.
Incorrect. `become` does change drop order - https://play.rust-lang.org/?version=nightly&mode=debug&editi....
That's not implementing tail calls breaks things, that's bad design of implementing tail calls breaking things.
The whole idea of "let's change semantics to make it easier" is dumb.
If you want guaranteed tail calls, change your code until it works.
Uh, yes, if you guarantee the semantics only when the code explicitly opts in and not by default then semantics will not subtly change, that is the point of my comment
It's not a change in semantics of compiled code. It is only a change of whether or not the code will compile.
Do any widely used languages guarantee tail call optimization? It's a pretty niche feature.
Scala, ocaml, racket, clojure, zig.
For recursion only kotlin.
(For most of these only with syntax specifying it)
When triaging an issue you have to prioritise. Do you fix a problem that affects 2-3 people or one that may affect thousands?
The point is that such bugs shouldn't exist in the first place.
Using recursion on unbounded inputs on a programming language that doesn't support that (which are most) is an extremely classical mistake that really should be known to all programmers, especially those of low level languages that care about safety.

Rust ? Because of ... memory safety. /s
That way of thinking just means it'll never be fixed

They have forced systemd despite feedback and genuine concerns.
They have forced fake sudo and uutils the same way.
So, ideology over merit. That doesn't mean that all of the Ubuntu devs are this way, but this means that the company is consistent in its ways to hurt Linux.
“Hurd Linux”? Maybe leave that judgement to Torvalds.
Canonical is a company they do what the CEO wants. And you are free to do what you want.
Quick question: are the fruits of your labor mostly given away for free?

Did you mean nothing "but" good?
Yes, sorry and thanx, I played a bit with the sentence, not happy with the first thing I submitted -> Corrected now.
"nothing good" is more accurate

Probably true, but the direction Linux is going these days is concerning
It's important to remember that this is a story about Ubuntu, and not Linux, and they are two very different projects with different motivations.
It does not matter. Both (Ubuntu [0], and the Linux Kernel [1]) use, build with and in some cases promote using LLMs.

True, and that's a bummer, but it's the decision of the maintainers of those projects to make.
If it goes really sideways, and it may, you can either fork Linux or move away to something like one of the BSDs.
Care to elaborate?
GPL -> MIT
Does this actually matter that much for some tools when the kernel is GPL?
I does. The OP says "Linux" but means "Linux distros", which are made of thousands of "commingled" pieces (i.e. the licence of one piece does not affect the other).
Each piece that becomes MIT means less pressure on corporate users to give back any changes they make, and we'll end back up in the 1980s again where "Amazon Linux" is full of secret-sauce they refuse to publish and makes the base system incompatible with "Google Linux" (or whatever happens to be kicking about), creating deliberate lock-in out of a system that started open. In much the same way that macOS and FreeBSD are divergent today.
In theory there could be a the MIT version relicensed to GPL and this version could be carried as a standard if having MIT software as core utilities was considered enough of a threat - right? You just have to retain original license/attribution.
That would be an awfully awkward move in the realm of Linux-related politics but if having an MIT-licensed coreutils was such an existential thread, at least you can fix it with aggressive license moves and not code.
That doesn't matter. Amazon or whoever can add as much secret sauce as they like; people can freely use the original so there's no issue.
We've balkanized Linux but you're free to use the original (which we are deliberately incompatible with, as is rival #2, rival #3, rival #4, etc. and we're all mutually incompatible with each other)
Amazon and other clouds already patch the hell out of Linux, but they don't distribute physical devices with that Linux on it to anyone, so they don't have to deliver source code either.
I am not totally sure I see the actual concern here, that a company is going to sell devices with a really great `find` implementation but not contribute it upstream?
In the 1980s and 1990s, there were a number of commercial Unices (SunOS, HP-UX, AIX, IRIX, etc.) Every one of them was incompatible with each other, sometimes subtly, sometimes blatantly. They were all competing against each other and all seemed to encourage you to use their proprietary extensions in your software and deliberately fuck over anyone using any other variants.
What it meant was a headache for writing platform-agnostic software. It was not a productive way to create software.
Replacing GPL software with MIT software just encourages this behaviour to come back. We already see it with how macOS userland took FreeBSD and sprinkled incompatibilities everywhere.
“Concerning” is just a right wing thing to say. They get the habit from Musk. They say it and don’t elaborate, so it kinda operates like a dog whistle.
Great "elaboration" (actually it's an "example"), indeed pulling everything into the political dimension is one of the concerning things regarding anything Linux nowadays, imho. Next up: DHH!
1) Corporate forced slop acceptance by e.g. Linus and Debian.
2) Seeing how bad the Linux kernel is with all the AI CVEs. It will get worse.
BSD is the future.
Netcraft may confirm that some day
BSD is the future. Wishful thinking. Nothing bad about it, but chances are low.
Ss for AI slop. There is lots, but I do not think Linus will tolerate a heavy quality degradation and policies will be set up to strike a good balance.
You were down voted, odd. But this I fully agree with, the latest thing for me is Wayland being forced upon us.
X11 and everything around it is unfixable security hazard slop, just slop that was painstakingly created by humans.
Also Wayland is it being forced on us? I have plenty of coworkers that run X daily because they are still afraid of the Wayland boogeyman despite the fact that their supposed clipboard and screen sharing problems in Wayland (the only two supposed problems they can name) have been solved for years.

I went upstream and started using Debian instead. Don't listen to the haters: it updates at about the same frequency as Ubuntu LTS.
Or just use Arch, and skip the pointless hype squad
Funny .. Arch started growing on me.
Or Pop!_OS that does not vibe slop their distro.
you are being sarcastic right?

The project was started long before LLMs existed.

There have been twelve CVEs reported against coreutils in the past twenty years.
There were forty-four against this project in just the last audit.
I am all for RIIR in cases where it makes sense. This does not even remotely appear to be one of them. By all appearances the quality of the code is extremely amateurish at best. coreutils has not been a significant source of vulnerabilities in the past, and they’re replacing it with code written by amateurs that performs worse and already has a worse security track record.
> There were forty-four against this project in just the last audit.
Was there an audit against coreutils? If not, it's not really apple-to-apple comparison.
It doesn’t even matter. The sheer disparity in vulnerabilities over twenty years versus one year is impossible to hand-wave away.
We are talking about fourfold more CVEs over a twentyfold reduction in time.
It really does matter. I don't know enough about this specific case, but multiple order of magnitude differences in CVE numbers are frequently explained by different policies towards finding and assigning CVEs in many many cases.
Absent more information the default should be to hand wave it away as probably such a difference. CVE counts are not a even slightly reliable metric.
Most of them are TOCTOU races or improperly following symbolic links. For example, uutils mkfifo(1) would create a world-readable and writable FIFO before using chmod(2) to restrict its permissions. Another user could replace that file with a symbolic link between the mkfifo(3) call and the chmod(2) to change the permissions of arbitrary files [1].
Other ones I find concerning are that you could also bypass '-- no-preserve-root' with a symbolic link to root [2]. Or by using paths equivalent to "/", e.g., "/../" [3]. Historically, GNU coreutils has been pretty good with symbolic links and avoiding TOCTOU races. The only notable one I can remember is a chmod(1) bug [4].
I agree with your general point that the number of CVEs is a useless metric, though.

From the company that distributed Amazon spyware (https://www.fsf.org/blogs/rms/ubuntu-spyware-what-to-do) and now turns Debian into Slopian. No thanks.
