Upstreaming MPTCP: the road to (hell) kernel. Any resemblance to actual events is purely coincidental

Danilo Krummrich on Rust in the #Linux kernel. #kr2026

Some C corner cases :

missed return on the error path;

kernel structs like struct completion are self-referential, so they must not be moved after initialization;

use-after-free through a stale reference. A Handler borrowing a Channel can't outlive it

Now Danilo Krummrich on stage in #kr2026

Enforcing Device Driver Lifecycle Rules at Compile Time

free memory is wasted memory, and so is cold memory.

Swapping out cold anonymous folios lets the kernel cache more and do less IO, so everyday things like git log or grep get faster.

Allocation moves to mandatory 2MB swap clusters, always kept on per-state lists, so allocating becomes a list-head lookup with no global operations and far less lock contention.

The scattered per-slot metadata is merged into a single swap table.

Already day 3 of Kernel Recipes.

The calm before the storm (a.k.a. before lunch is called)

A few essential pointers: tools to get through the next 18 months, which are likely to be very rough.

Survival guide for the age of bots #kr2026:

If it feels wrong, it probably is
Ignore the doom marketing
Keep your models at home
NEVER feed them anything non-public
Found a bug? Fix it. Today. Yourself

Meanwhile, the kernel security team now asks for a patch with your report. Revolutionary concept

This is happening on a daily basis!

The main point is: DON'T PANIC:!
... At the end 10 bugs fixed, 1hour kernel development...

Stay tuned: live blog - day 2 - afternoon
