Linus has released the 5.13 kernel.

Of course, if the last week was small and calm, 5.13 overall is actually fairly large. In fact, it’s one of the bigger 5.x releases, with over 16k commits (over 17k if you count merges), from over 2k developers. But it’s a ‘big all over’ kind of thing, not something particular that stands out as particularly unusual.

Headline features in this release include the “misc” group controller, multiple sources for trusted keys, kernel stack randomization on every system call, support for Clang control-flow integrity enforcement, the ability to call kernel functions directly from BPF programs, minor-fault handling for userfaultfd(), the removal of /dev/kmem, the Landlock security module, and, of course, thousands of cleanups and fixes.

    sigh let’s see which regressions this has in store for me this time :)

    I think the sheer amount of devices Linux runs on nowadays makes it very hard to avoid things just not working™ anymore.

    Any idea on how to avoid regressions? Integration tests for GUI applications? Automated tests for booting? Is there a test suite?

    I believe fixes for the antics from the University of Minnesota also begin landing in this release.
