Post Syndicated from original https://lwn.net/Articles/861131/rss

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.
