Somebody is spamming kernel mailing lists under the name Marian Corcodel with a 26 MByte message multiple times per day containing a collection of nonsensical patches. Looks AI-generated, perhaps with the intention to poison LLMs. This has been going on for a few days now.
https://lore.kernel.org/all/CAGg4U=GNtCObd_Nbm_1Rr5FEvPb69Yz...
HN gets 24M views a day. Assume those views are evenly distributed across the front page (they aren’t), and that’s about 1M views for each front page post, assuming each user clicks on one post.
By the rule of 10s (also not exact), there are 10x less views on comment threads. So assume around 100k views on a comment thread as a theoretical average.
If everyone in this thread clicked on the link, that would be 2.6 TB of transfer across the day. But by the rule of 10’s we have to assume 10x fewer people will interact (upvote, click, anything) than view. So we’re down to 260GB transfer over the course of a day.
I wonder how close that is. It seems plausible that a link in the top comment of a thread could garner 10,000 clicks.
That’s still about one click every 8 seconds, which at 10Mbit/s would indeed overwhelm the server by a factor of about 2.5x. But I clicked through and it loaded in just a few seconds, so presumably the pipe is faster than 10Mbit/s.
Another caveat is that many websites are already several megabytes, so it seems strange that 26Mb would be the breaking point for a reasonable web host.
How does that work?
Actual context: Linux 7.1-rc4 release, Linus remarked on a specific documentation change.
The Register somehow turned this into an "article" that says a lot less with roughly the same number of words, and provides "context" by linking to a number of unrelated articles.
Does it? Both points can be true at the same time.
“AI tools are great, but only if they actually help, rather than cause unnecessary pain and pointless make-believe work,” he wrote. “Feel free to use them, but use them in a way that is productive and makes for a better experience.”
So I think the closing remark from the register isn’t really appropriate given the context from the quotes they pulled.
The problem is people trying to get individual credit for merely running a script that spams a mailing list. Many of those people are likely not even C programmers or programmers at all.
Without the immense personal reward and recognition and job offers as a motivation, the problem will disappear.
The problem will also disappear with time as the people lauding and celebrating and hiring security researchers of the past will quickly abandon LLM generated spam as a positive signal; running a prompt that sends spam is, if anything, a strong negative indicator of infosec ability and skill.
LLMs are a tool. Like all tools, most people can't or won't use them responsibly or profitably although they are useful in the correct hands.
It probably doesn't really change that much in this scenario but with a forum or any other topics-based platform you can at least just close and ignore these things without it affecting everyone else.

True, external moderation is a benefit of centralized platforms, but a mailclient allows personalized moderation, which allows with a well organized list to only filter out anything you are not interested in. Usenet had the benefit of both, a centralized platform with moderation, and powerful clients for further personalization. Too bad it died for most usages.
Thats kinda a misrepresentation. They are talking about two different things. Linus is trying to point out incorrect use of a tool while GKH is praising a correct use. This sentence felt weird at the end of the article, kind like rage bait. And I took it :P.
That said, I get why this would rankle a lot of the folks involved.
Imagine the current state being for the most part a collection of local maxima in security. To push the system in a more optimal state, you either need skilled people and time to overcome the barrier to a new local maximum or you throw AI at it and evaluate whether you land in a more optimal state.
I think after some time of turbulent exploit/patch cycles we will reach a stable state again, where the code converges against a new local minimum that even with AI requires significant effort (time and tokens) to overcome. Or ideally a global maximum.
With time, the LLMs improve, so the diffs/gradients get better and we will be able to reach optimal points for any software faster.
My problem with the idea is that apparently it is assumed that OSS contributors and especially maintainers will generously donate their time to get this machinery into a state that makes the optimization loop work well - just for the AI labs to turn around and sell access to the optimized models for increasingly larger amounts of money.
AI generated code can be great. Hand rolled code can be bad. The rules are the same in both cases. Make sure your code changes are focused (no random changes just because you happen to be in the file/dir or notice something) and make sure you don't break anything else along the way.

From what I’ve seen many of the AI bug search operators are newer to security research. They’re burning their tokens trying to find kernel bugs as their claim to fame before other people with AI tools find them first. They don’t spend time de-duplicating their own bugs.
Some of them may not be coming from real people. There are honeypot repos that are entirely fake and only have folders of simple files with clear security problems. They collect automated reports they get from all of the AI bots that people are running.
On the other hand ... IF the bug report is real, and let's assume that AI slop reports at the least a few bugs that are indeed real, then I really think it should not make a difference WHO or WHAT reports these bugs. I would not disagree on fake bugs or bogus bug reports wasting time of humans, but this is a quality difference then. Surely people can tweak AI models to be better at finding bugs too. Besides, they should auto-fix that. Is AI still too stupid to fully replace humans? Other than killing them with spam, as it does right now.
It will almost likely find issues that require fundamental design changes to even fix some of these
Dangerous waters ahead for data security and vital infrastructure
It's a catch 22. Why not make a separate list for AI generated reports that can be subscribed to instead? If the claim is that these are not private anyhow, no reason not to, and then a reasonable expectation could be held against submitters to check against existing reports.
That is unless it is still absolutely sensitive, in which case the only way forward that I see is to start using AI for triaging and duplicate detection as well.

Over the last year there have been way too many stories and Twitter posts like these.
Yes, maintainers are overloaded, but that's only because we haven't yet built the tools to support them.
Other than such statements, I would, as a builder like to hear the sorts of tools and requirements maintainers are looking for which would make their work easier!
We need to move fast without breaking things.
This is available info?
2022 from dang:
> There's no stats page but last I checked it was around 5M monthly unique users (depending on how you count them), perhaps 10M page views a day (including a guess at API traffic), and something like 1300 submissions (stories) and 13k comments a day.
> The most interesting number is the 1300 submissions because that hasn't grown since 2011 - it just fluctuates. Everything else has been growing more or less linearly for a long time, which is how we like it.

It's a big problem. Donate to Archive.org if you can!
see "If you resorted to AI assistance to identify a bug, you must treat it as public." and https://docs.kernel.org/process/security-bugs.html#responsib...
(and at least weird isn't like uncanny-valley-ai-written-weird)
it's just that in the past people most times didn't find security vulnerabilities independently of each other without knowing about the others en mass
worse it's non trivial to dedup on the submitter side, nor on the receiver site (as long as we stay with a classical mailing list format)
and while this might be fixable with an AI auto grouping duplicates etc. getting that right is _hard_ especially if we consider that there can be a lot to gain for an adversary to use prompt injection and similar to cause an effective "hiding" of "useful" security issues (e.g. by wrongly causing them being labeling as duplicate).
In addition to all the technical problems this causes some other problems: 1.) additional cost you can intentional (maliciously) increase 2.) dependence on some LLM provider 3.) trust problem wrt. the used LLM provider. Some of this can be avoided by running open models on sponsored owned hardware, but at the cost of often outdated LLM tech, higher cost, now needing to maintain additional hardware etc.
Not exactly, the submissions are reports about actual existing security issues. They are make-believe work because everybody has access to AI, and anybody could have done it. Deduping is not productive work, it's a search for productive work.
Instead of spamming bug reports generated by AI, people should spam cash or token credit of some sort so the project can generate these themselves. The real unnecessary part of the entire process is the submitter. There's no need for an AI middleman.
If somebody comes up with some witty trick that gets an AI to find a bug that it wouldn't have found on its own, submit the prompt.
A few of us will actually use these tools to reduce toil and achieve something useful.

People will spam continuously anyways, for whatever motivation they have (trolling, ai poisoning, hate, etc) and it will become harder to filter through the noise.
If you have emails attached, I can confirm that Linus in fact posted something and its probably worth reading. You can gain reputation and I can filter my attention based upon those who have reputation.
It's not clear to me that the spammer discussed in this thread is motivated by recognition and job offerings. I don't think this solves it.
The kernel isn't the only OSS project with this issue either. Requiring submissions & issues to be anonymous could help a ton of other open source projects currently drowning in AI slop issues.
The people who have this preference are processing the mailing lists with a highly specialized mailtool, not a web browser.
If you have only ever accessed email with a web browser it is not surprising that you find the mailing list format weird.
Mailing lists allow people to use threads if they want (assuming nobody thrashes the threads headers by using terrible email software from Microsoft/Google), and also allows people to read from the firehose if the want. And there's plenty of threaded web views of mailing lists available for lurkers.
I remember when it was popular, computers had limited storage and bandwidth, and you had to "sip" usenet articles because it was a giant firehose of data, mostly hand-typed text. (excepting alt.binaries.*)
Local filtering is the key to ignoring threads you are not interested in. Depending on the client with 2 or 3 keystrokes you are ignoring the whole thread or this particular sub branch of it and automatically jumping to the next interesting, unread message.
They are simply more efficient and more importantly censoring is done by the user themselves, not by politically motivated admins who ban discussions based on their ideologies and whims.
"I like it this way because it's always been this way and once you change your entire email workflow and customize your email client, it's almost as good as PHPbb"
Forums are built for threads and are immediately visible and accessible for everyone, not just people who want to spend their limited time dicking with email clients.
Mailing lists are the proto-discord: knowledge locked away from the public behind a special frontend and elitist attitudes. It's only better because the list is technically visible, but only in the worst, most low-effort way possible. You dump a raw txt copy of the entire thread unstructured onto the user and make it their problem to figure out. After all, your email client makes it easy to read, so why should you care about what anyone else needs?
This discussion has been happening since forever. And also the idea that it serves anyone to complain how others are obviously doing it wrong, without even attempting to understand why they’re doing it a certain way. And then be irritated when the response is negative, and labeling others as elitist for using and providing open platforms over decades and not silos.
If you don’t know, feel free to ask. And then suggest (or provide!) improvements that factor in current requirements and goals instead of dismissing them as stupid.
Life advice: if you want anybody to change what they do, you need to first understand why they’re doing it, and then offer suggestions based on that understanding that improve it with them. Otherwise you’re going to continue to recreate your own victim position, and an “elite” position that you will never belong to.
At the same time, it's often technically true, but for a good reason that you neglected to mention:
Those old tools tend to be very capable email clients, not web apps with their awkward attempts to simplify complex conversation structure. A good email client can handle large, high-traffic, frequently branching, long-lived threads with ease. All the web forums I've ever used fail miserably here.
The people who are tasked with participating in large scale discussion groups (like the LKML) know this through experience. They prefer email because it works better. It makes their lives easier. It helps them to be more efficient, which is absolutely necessary given the sheer volume of messaging that they handle.
Yes, a specialized tool is required to get these benefits, just as a specialized tool is required to make web server output easily readable. Thankfully, these tools have existed for decades.
I prefer people to email me because half of the time they figure out their problems while writing them.
it's not an absolute rule but people who don't do their homework gravitate towards calls and messaging because they just don't prepare their questions.
asynchronous communication puts the burden on the sender, where it belongs.
would you give up text messages or email?
Many "new" tools are basically the old tools with a few additions like emojis and pictures.
I do think upvoting was one "technology" that did make discussion forums different than mailing lists, but that put them under control of someone and had different drawbacks. hn is a good example, reddit is one devolving example
easy to archive and open format too
But now we need an AI tool to consolidate the triage utilities.
[dead]
This is just a workflow issue. In the past it was very rare for multiple people to find and report a security vulnerability at once, so it made sense to keep the discussion private until they were ready to release a fix. With AI that is happening all the time, so it makes more sense for the discussion to be in public to avoid duplication. So they changed the policy accordingly. That is it.
Interestingly enough doing that type of triage is something LLMs are actually great at

Or, put another way -- what flags the duplicate? The filer or the system? If my cheese factory is measured by the volume of cheese instead of the quality, I'll churn out the cheese even if it's sloppy duplicated cheese. And that is the case if a person has to flag a new ticket as "same as this" or not.
What's that law that says that any sufficiently large problem turns into a moderation problem?
Unless the kernel community starts banning & publicly shaming repeat offenders, there's zero incentive for them to put any effort in filtering out duplicates. They are mostly doing it for marketing after all, not out of a genuine interest in making the kernel better.
It can not because this mailing list is not public.
One could ban orgs that flood the zone with AI generated trash, but is there some potential middle ground where there are sets of filters to identify duplicated bugs, and possibly just internally dump "AI spam" to a lower queue?
This seems like the sort of problem I'd addressed in the 90s with killfiles and spamassassin. In other words, can't the ingestion just go through some filters to shield the humans at the end of the pipe?
Feel free to fork the kernel and maintain your own vibe-coded disaster.
It seems to be more about:
1. auto grouping duplicate security reports
2. auto validating if they are likely viable or likely nonsense
3. auto checking if they have recently been patched
4. auto assessing if they likely "invalide" for other reasons (e.g. they are for a very old long time no longer maintained Linux version, out of tree drivers, etc.)
I mean practically all of that isn't trivial to get working in a way appropriate for the Linux security mailing list and comes with many not so obvious complications. But also non of that is vibe coding and in most cases this is is more about AI doing a per-assemsment of send security issues to speed up the review of them, then it is about the AI doing the final decision.
At the end of the day, we would rather have a more stable and bug-free kernel than not.
It's not that much work for me anymore to report and even fix that obscure monitor driver bug that sometimes causes my machine to bootloop, unless I boot without graphics and start the XOrg server manually.
I often find myself surprised at how easily frontier models are able to find bugs across abstraction layers, that only original authors can comprehend. We need more positivity around these contributions as well.
How about we just reduce the noise?
AI trash like this is like showing up to a baseball game with a pitching machine and demanding that they let you join in and be the pitcher using your machine. Just because your slop cannon is fun and exciting to you doesn't make anyone else obligated to join your club just because you fired your slop on them.
Today's preteens will be pining for Discord in the 2050s era of AI Neuralink vibe-telepathy. They'll say once you change your entire workflow and customize your client, phpBB is almost as good as Roblox chat or TikTok comments.
