New AF_ALG Restrictions With Linux 7.3 Due To The Security & Maintenance Nightmare

The past few Linux kernel cycles have chipped away at AF_ALG functionality for that interface for user-space programs to access the kernel's internal cryptography API. Linux has been dropping AF_ALG features like zero-copy support and offloading. AF_ALG was quickly deprecated in Linux 7.2 while now for Linux 7.3 it's being further restricted...

Linux 7.3 Improving RAID 5/6 Benchmark-Based Algorithm Selection

Following the main set of memory management "MM" changes submitted for Linux 7.3, Andrew Morton sent in his "non-MM" pull request of the other patches he's been collecting from various developers for this next Linux kernel release. Standing out there were some improvements to the RAID 5/6 benchmark-based algorithm selection...
