Understatement of the year:

Finally converted usbutils over to meson from autotools. Odds are I messed something up, so I should do a release soon to see what broke in the distros as I have no idea how they package this thing anymore:

New blogpost about creating bit-by-bit reproducible images with mkosi(!)

My boss: "how is that Gemini AI trial going? Are you making good use of it?"
Me: "Oh, yeah, for sure."

In non-CVE news, here's some fun hardware I got while visiting Hong Kong. It's not the snappiest laptop I've ever used, but it holds potential!

Kernel source is all public (there's a 6.1.y and 6.6.y tree at the moment), hopefully will start working on getting it all merged upstream to make it a proper platform for others to use.

So far this year the Linux Kernel has done 3000 CVEs even. This means we can expect roughly 4500 for this year in total. Bu I have good news: they only started in Feb so we can expect another 10-15% on top of that for 2025, so with any luck that'll be about 5000. In other words 12.5% or so of TOTAL CVE activity.

So when @gregkh says run current, you need to listen.

You can spend several thousand hours a year trying to triage Linux Kernel vulns, or you can invest that effort into automation (updates, builds, testing, etc.) and stay current and answer "did you fix CVE foo" with either a "yes" or a "that will go out in the next update at future time X".

I'd really like to read a well researched article that sums up how Linux distros reacted to the massive influx of #Linux #kernel CVE that started ~half a year – both for their #LinuxKernel packages and their live-patching offerings.

But I guess that is an enormous amount of work that no media outlet in this world is willing to pay anyone for writing. 😕

Slide taken from @gregkh's "Why are there so many kernel CVEs?" talk he gave at OSS China yesterday (https://social.kernel.org/objects/c9979d9f-399f-428b-ac56-c41598076dfa ) #LinuxKernel

Don't panic! It's only 60 Linux CVE security bulletins a week https://zdnet.com/article/dont-panic-its-only-60-linux-cve-security-bulletins-a-week/ by @sjvn

Sure, it sounds like a lot, but it's just business as usual for #Linux #security.

It was fun, and will be the "set up" for my Kernel Recipes talk in Paris in a few weeks (only 3 conferences to go between now and then, travel is back in full swing.)

Ok, so the day has come. On the context of getting "/usr merge" on alpine, I am going to try update the FHS.

9 years after it was updated, big parts of it are out-of-sync with the current Linux distro conventions.

We (@postmarketOS) already pinged the @linuxfoundation about it in February, and their suggestion was to get somebody interested to do the work. So let's start that process now! Since the FHS mailing list seems defunc (I subscribed and sent an email in February that never got added to the archive), please send me an email at pabloyoyoista@postmarketos.org so we can get a list of people to start discussing the process

Recently, a Dutch hacker found a vulnerability allowing him to shut down 4 million solar power installations. A handful of mostly non-European places manage perhaps 100 GW of solar power in the EU. Any mishap there, or heaven forbid, a compromise, could easily shut down so much power that the European electricity grid would collapse. Shockingly, we regulate these massive control panels as if they are online birthday calendars. And that must change. https://berthub.eu/articles/posts/the-gigantic-unregulated-power-plants-in-the-cloud/

I think I finally found out why it feels like CISA live on Alpha Centauri.

> “It’s a myth,” she declared, “that software vulnerability is an inevitability. … It’s the same classes of defects we’ve known about for decades and known how to fix for years.”

This is both true and utterly wrong. It is true, we know how to detect and fix them for decades. In research.

But you know what we do not have? Industry tool that can be used in the industry based on this knowledge.

"Linux would have prevented this!" literally true because my former colleague KP Singh wrote a kernel security module that lets EDR implementations load ebpf into the kernel to monitor and act on security hooks and Crowdstrike now uses that rather than requiring its own kernel module that would otherwise absolutely have allowed this to happen, so everyone please say thank you to him

don't let anyone ruin your day

it's YOUR day!

ruin it yourself by attempting a gentoo install

I just wrote a blog post about how to use the new counted_by attribute in C and the Linux kernel. I've been mentioning this attribute in my presentations over the past year, and I thought it was about time to write about it. So, here you go:

@bert_hubert Bert's talk is all the more important when you combine it with stuff like this: https://www.propublica.org/article/microsoft-solarwinds-golden-saml-data-breach-russian-hackers
