OpenSSH 10.4 has been released. In addition to a number of security and bug fixes, there are a few notable changes; this release adds experimental support for a composite post-quantum signature scheme combining ML-DSA 44 and Ed25519 as described in this IETF draft. With 10.4, if OpenSSH is compiled with sandbox support it will fail on Linux systems that have not enabled SECCOMP or NO_NEW_PRIVS; prior to this release, sshd would log an error but continue operation. See the release notes for a full list of changes.
Conversations about the kernel's filesystem implementations often involve a layer called "iomap", but relatively few people can reliably say what iomap actually is. That is just the kind of gap that LWN exists to fill. In short, iomap handles the mapping between data in the filesystem space (identified by a file of interest, and an offset within that file) and in the storage space (which may be a memory location, or a set of blocks on a storage device). Using that mapping, iomap handles a long list of common, filesystem-related tasks, allowing a lot of boilerplate code to be removed from individual filesystem implementations.
With the AMD Ryzen AI Halo developer platform there is the option of ordering this Ryzen AI Max+ mini PC with either Microsoft Windows 11 or "Linux OS". When receiving a AMD Ryzen AI Halo review sample last month, I fully expected it to just be an Ubuntu LTS install with ROCm preloaded. I was quite surprised when powering it up to find that it's an OS called the AMD Ryzen AI Developer Platform 1 "Rex" and is based on Debian Linux.
Earlier this year AMD announced the Ryzen AI Halo as their in-house mini PC offering built around their leading Ryzen AI Max+ "Strix Halo" platform. After pre-orders began last month, the Ryzen AI Halo is officially beginning to ship this week and over the past few weeks we have been testing it out at Phoronix.
