In which I explain how I will treat LLM generated or assisted patches for the Linux kernel drivers/staging/ subsystem going forward:
https://lore.kernel.org/all/2026080354-skater-urgent-31b2@gregkh/T/#u

(hint, not allowed, except for security bugs that you can prove actually fix something by testing the issue on the actual hardware the driver controls.)

After totally messing up my gdm configuration by foolishly using `gdm-settings` (I didn't want the machine to suspend at the login screen for obvious reasons that doesn't play well with logging into it from other boxes), causing it to not properly even show a login screen, I've reverted back to running plasma and realizing it's been a long time since I last ran KDE and how nice it's gotten since then.

So, until I figure out how to wipe all gdm settings from the system (hint, I tried the "reset" option on gdm-settings and to blow away all dconf files that i could find on the disk, but odds are I missed something), I guess I'm now a KDE user until I move to a new system...

Starting to write up a series of articles about the Linux kernel CVE work that has happened in the past 2 years, starting with some "back to basics" information about how Linux kernels are numbered as many people/companies really don't know how we do this, and it matters a lot in tracking bugfixes and how to determine "vulnerable" and "fixed" kernel releases:

The last 5.4.y kernel release has now happened: https://lore.kernel.org/all/2025120319-blip-grime-93e8@gregkh/

Please don't use this branch anymore, it's really old, and pretty obsolete, and has over 1500 unfixed CVEs in it:
https://lore.kernel.org/all/2025120358-skating-outage-7c61@gregkh/

And if you are stuck with that kernel version for some reason, go ask your vendor to fix those 1500+ CVEs, otherwise you are paying for support that doesn't actually do anything for you...

"I'm probably not alone in thinking that sometimes the compiler writers are doing their hardest to make life hard for people writing low level code." -- David Laight at: https://lore.kernel.org/r/344b4cf41a474377b3d2cbf6302de703@AcuMS.aculab.com

It's a fun thread, recommended for anyone who deals with compilers and trying to get them to do what you would think would be a "easy" thing to do and the hacks around them to get them to do that (hint adding "+ 0" to an expression tricks the compiler into doing what you meant it to do is usually a sign that something is wrong somewhere...)

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:
