ConfigFS is seeing a new maintainer step up to manage this RAM-based file-system. With Andreas Hindborg taking over maintainership of ConfigFS he’s also landing patches authored by him for adding Rust programming language support to this file-system.
ConfigFS is a RAM-based file-system for a converse of sysfs functionality for user-space driven kernel object configuration. ConfigFS makes it easy to expose kernel data structures for different purposes. With Linux 6.16 there is now going to be a Rust API to ConfigFS for having a memory-safe API for interacting with it. As part of the Rust integration is also adding a sample Rust program for demonstrating the ConfigFS + Rust interface.
The ConfigFS code for Linux 6.16 also now allows creating read-write files with custom permissions to better protect secrets written through ConfigFS.
More details on the ConfigFS changes for Linux 6.16 via this pull request. This was one of the early pull requests submitted in advance of the Linux 6.15 stable release to prepare for the imminent merge window.
