OpenSSL 3.0.7 Released Fixing Critical Flaw — Today we published an advisory about CVE-2022-3786 (“X.509 Email Address Variable Length Buffer Overflow”) and CVE-2022-3602 (“X.509 Email Address 4-byte Buffer Overflow”).
OpenSSL version 3.0.7 published
/news/openssl-3.0-notes.html
Fedora 37 Release Delayed To Mid-November Over Critical OpenSSL Vulnerability
Linux 6.2 Power-Savings While Idle Or Lightly Loaded — The short story for Linux end-users is the Lazy RCU work can provide 5~10% power-savings for idle or lightly-loaded systems by this lazy/batching functionality.
Linux 6.2 Picking Up Mainline Support For Apple M1 Pro/Max/Ultra Hardware — This gets the high-end Mac Studio systems with those premium SoCs now compatible with the mainline kernel.
Hector's Deleted Tweet — I'm getting tired of arguing with kernel maintainers. The other day I spent 6 hours arguing on IRC about what should've been a 30 minute fix patch.
Hector Martin on Twitter Follow Up Tweet — Like dude, if you aren't going to step into my world and actually understand what I'm trying to do here, just suck it up and ack my patch. It is not my job to drag you kicking and screaming until you either give up or have a lightbulb moment.
Seems some Kernel Maintainers Noticed the Twitter Rant — Well they saw my tweets and apparently didn't like them 🤷‍♂️
Bcachefs Rolling Out New Allocator, Performance Continues Improving — Bcachefs developer Kent Overstreet on Friday published a new status update on this original file-system born out of Linux's block cache (BCache) code.
FreeBSD Re-Introduces WireGuard Support Into Its Kernel — As of Friday, a new WireGuard driver implementation has been re-introduced with many fixes/improvements over the code state from 2020.
Open Letter to Gitea - Restoring Trust in the Gitea Project — This unfortunately concludes the Gitea Open Letter has failed and there is no alternative but forking the project under a new name, with a healthy democratic governance.

Ubuntu gets a new rolling-release remix — The new flavor is the brainchild of MrBeeBenson, building on work by Martin Wimpress, who is the project leader of the Ubuntu MATE remix.
AMD Recruiting More Linux Engineers For Debug, CXL Enablement & More — Notable with their latest batch of Linux openings is hiring a CXL engineer. This role will focus on AMD's support for Compute Express Link (CXL) hardware enablement under Linux.
WirePlumber 0.4.9 Fixes Surround Sound For Some Linux Games — It was reported that some games within Steam were not able to enjoy 5.1 surround sound with PipeWire in a year-old bug report. A fix landed in WirePlumber a month ago to relax the format parsing within the si-audio-adapter module and this appears to fix up that issue
New Linux kernel patch speeds up server shutdowns — The problem is caused by the relatively long time it takes to properly shut down an NVMe drive: apparently, as much as four-and-a-half seconds.
Linux 5.18 Hardens The Kernel For 64-bit Arm With Shadow Call Stack Support — With the Linux 5.18 hardening updates there is support added for ARM64 (AArch64) Shadow Call Stack support when building the Linux kernel with GCC 12 and newer.
Linux 5.18 Power Management Brings Improvements For Both Intel & AMD — Intel's P-State driver will now use the default default Energy Performance Preference (EPP) exposed by the firmware, and over on the AMD CPU side, the CPUPower utility that lives within the kernel source tree now supports running in conjunction with the AMD P-State driver.
Linux 5.18 Moves Ahead With Deprecating ReiserFS — The plan is to treat it as deprecated and formally remove it from the mainline Linux kernel in 2025.
XFS Online Repair Functionality To Undergo A Massive Design Review — XFS online repair has been talked about for years along with online scrubbing and it looks like it's about all buttoned up. Darrick Wong will be spending the next roughly two months focusing on the "massive" design review for XFS online repair code.
Problems emerge for a unified /dev/*random — A bunch of changes for the kernel random-number generator (RNG) were merged by Linus Torvalds on March 21. Unfortunately a user-space regression surfaced that led Torvalds to say that he would revert the patch. The idea was good, but it "causes problems for various platforms that can't do jitter entropy and have nothing else happening either".
