Linus Torvalds Growing Frustrated By Buggy Hardware & Theoretical CPU Attacks
21 October 2024 - Frustrated Torvalds

Over the past week Linux creator Linus Torvalds has been active on a Linux kernel mailing list thread around avoiding barrier_nospec() in copy_from_user() due to being "overkill and painfully slow." The conversation evolved into low-level discussions over CPU behavior and how to best handle, differing behavior/requirements with new Intel CPUs supporting Linear Address Masking (LAM), and the overall headaches these days around CPU security mitigations.

Several Linux Kernel Driver Maintainers Removed Due To Their Association To Russia
22 October 2024 - Russian Linux Kernel Maintainers

Quietly merged into this week's Linux 6.12-rc4 kernel was a patch that removes a number of kernel maintainers from being noted in the official MAINTAINERS file that recognizes all of the driver and subsystem maintainers.

Significant CRC32C Throughput Optimization On The Way To The Linux Kernel
23 October 2024 - Faster CRC32C Performance

Google engineer Eric Biggers has worked on some very nice performance optimizations for the crypto code within the Linux kernel such as faster AES-GCM for Intel and AMD CPUs, much faster AES-XTS disk/file encryption with modern CPUs, and many other optimizations over the years. His latest work is on enhancing the CRC32C crypto performance for x86/x86_64 processors.

Linus Torvalds Comments On The Russian Linux Maintainers Being Delisted
23 October 2024 - It's Staying That Way

Following yesterday's news first featured on Phoronix of several Linux driver maintainers being de-listed from their maintainer positions within the mainline Linux kernel over their connections to Russia, Linus Torvalds has today commented on the matter.

I'm not very good at writing utilities in C, so please excuse my use of bloated Python.🙃
Some Clarity On The Linux Kernel's "Compliance Requirements" Around Russian Sanctions
24 October 2024 - US Sanctions Requirements

When a number of Russian Linux developers were removed from their MAINTAINERS file in the Linux kernel, it was described as due to "compliance requirements" but vague in what those requirements entailed. Linus Torvalds then commented on the Russian Linux maintainers being de-listed and made it clear that they were done due to government compliance requirements / legal issues around Russia. Now today some additional light has been shed on those new Linux kernel "compliance requirements".

FUTEX2 NUMA & Small Futexes Revived For Linux
25 October 2024 - FUTEX2 NUMA + Small Futex

Back in 2020~2021 there was lots of talk and work around FUTEX2 for improving the Linux kernel's Futex implementation for fast user mutex. The FUTEX2 work was driven in large part for helping Steam Play / Wine gaming by better matching the behavior of Microsoft Windows with its WaitForMultipleObjects handling. While the initial code landed back in Linux 5.16, there's been other remaining FUTEX2 features still desired like variable-sized futexes and NUMA-awareness. Finally now we're seeing that work revived.

Linux 6.12-rc5 Disabling Intel's Linear Address Masking "LAM" Due To Security Concerns
27 October 2024 - Linear Address Masking

Intel merged Linear Address Masking into the Linux kernel last year as a means of allowing user-space to store metadata within some bits of pointers without masking it out before use. LAM can be useful for virtual machines, sanitizers / profiling / memory tagging, and other uses. While the brand new Intel Arrow Lake and Lunar Lake CPUs support LAM, the Linux kernel is now disabling LAM out of security concerns.

Sent out in original patch form this past week and already iterated to a second version this Sunday, a new proposal is underway to introduce "hung_task_detect_count" as a convenient means of tracking the number of times hung tasks are detected since boot.
