[$] Hash-based module integrity for reproducible distributions

Post Syndicated from jake original https://lwn.net/Articles/1100026/

We last looked in on hash-based integrity
checking for kernel modules
just over a year and half ago. Since that time,
the patch
set
has undergone multiple revisions. At the 2026 Linux Plumbers Conference
(LPC), Thomas Weißschuh described the need for kernel-module integrity
guarantees while still providing reproducible builds, how his patches implement that, and some ideas for possible
further work.
