Adiantum File-System Encryption Support Ready For Linux 4.21

Adiantum, Google's newly developed crypto algorithm to replace their planned use of the controversial Speck, is ready to begin providing speedy file-system encryption support for low-end devices with the upcoming Linux 4.21 merge window.

Bcachefs Working Towards Online Fsck, Faster Mount Times

In the works now for over three years has been BCachefs that doesn't receive nearly as much attention as Btrfs, Stratis, ZFS On Linux, or other next-gen Linux storage options, but it does continue making progress and still possesses a lot of potential.

There Is Finally A User-Space Utility To Make EROFS Linux File-Systems

Back when Huawei introduced the EROFS Linux file-system earlier this year, there wasn't any open-source user-space utility for actually making EROFS file-systems. Even when EROFS was merged into the mainline tree, the user-space utility was still non-existent but now that issue has been rectified.

Adiantum Is Taking Shape As Google's Speck Replacement For Low-End Device Encryption

Earlier this year when Google added Speck-based file-system encryption support to the Linux kernel they intended it to be used by low-end Android phones/smartwatches with older ARM processors lacking the dedicated ARM cryptography extensions. Speck is fast enough to provide disk encryption on the low-end hardware, but ultimately they decided against Speck due to public outcry with the algorithm potentially being compromised by the US NSA. Instead Google engineers decided to pursue HPolyC as their new means of encryption on low-end hardware while now that has evolved into a new technology dubbed Adiantum.

The Faster FUSE Has Been Fused Into Linux 4.20

While File-Systems in User-Space (FUSE) have been notorious for being slow, with time FUSE has become a lot faster and with this current Linux 4.20 (5.0) development cycle there are yet more performance optimizations.

XFS & EXT4 Offer Up Modest Changes For Linux 4.20~5.0

The changes are not as notable as Btrfs having multiple performance improvements or multiple new features for F2FS, but the XFS and EXT4 mature file-systems have their latest advancements now queued for the next kernel cycle.

F2FS Offers Up New Features For Linux 4.20/5.0

While Btrfs has been sorting out performance improvements, the crew working on the Flash-Friendly File-System (F2FS) have been working on a number of feature additions for this next Linux kernel under development.

FUSE Getting Another Performance Boost In Linux 4.20~5.0

Separate from the recent FUSE performance work talked about for making FUSE faster with the eBPF in-kernel JIT that hasn't been staged for mainlined, "File-Systems in User-Space" are set to see better performance on the next kernel (Linux 4.20~5.0) thanks to other changes.

ExtFUSE: Making FUSE File-Systems Faster With eBPF

Georgia Tech tends to be home to a lot of interesting open-source projects and incubating long-term FLOSS/Linux developers. This university's latest interesting open-source project is "ExtFUSE" for making user-space FUSE file-systems faster by making use of the in-kernel eBPF framework.

UBIFS & OverlayFS Updates Hit The Linux 4.19 Kernel

For the Linux 4.19 kernel there's been a lot of F2FS performance enhancements and more, the new EROFS file-system, low-level Btrfs improvements, and more. Some of the file-system work less in the spotlight are the OverlayFS and UBIFS updates sent in this week.
