• 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.

• 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".

• Linux has a serious security problem that once again enables DNS cache poisoning — We can actually guess the ephemeral port in the embedded UDP packet and package it in an ICMP probe to a DNS resolver. If the guessed port is correct, it causes some global resource in the Linux kernel to change, which can be indirectly observed. This is how the attacker can infer which ephemeral port is used.

To normal consumers, that's clearly not going to do much to help and probably scare them away. Now, instead, it will provide a very clear and friendly message, with the option to get more details to report the issue.
