Merge tag 'slab-for-6.6' of git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab
Pull slab updates from Vlastimil Babka:
"This happens to be a small one (due to summer I guess), and all
hardening related:
- Randomized kmalloc caches, by GONG, Ruiqi.
A new opt-in hardening feature to make heap spraying harder. It
creates multiple (16) copies of kmalloc caches, reducing the chance
of an attacker-controllable allocation site to land in the same
slab as e.g. an allocation site with use-after-free vulnerability.
The selection of the copy is derived from the allocation site
address, including a per-boot random seed.
- Stronger typing for hardened freelists in SLUB, by Jann Horn
Introduces a custom type for hardened freelist entries instead of
"void *" as those are not directly dereferencable. While reviewing
this, I've noticed opportunities for further cleanups in that code
and added those on top"
* tag 'slab-for-6.6' of git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab:
Randomized slab caches for kmalloc()
mm/slub: remove freelist_dereference()
mm/slub: remove redundant kasan_reset_tag() from freelist_ptr calculations
mm/slub: refactor freelist to use custom type

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
