Merge tag 'lsm-pr-20250926' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/lsm

Pull lsm updates from Paul Moore:

 - Move the management of the LSM BPF security blobs into the framework

   In order to enable multiple LSMs we need to allocate and free the
   various security blobs in the LSM framework and not the individual
   LSMs as they would end up stepping all over each other.

 - Leverage the lsm_bdev_alloc() helper in lsm_bdev_alloc()

   Make better use of our existing helper functions to reduce some code
   duplication.

 - Update the Rust cred code to use 'sync::aref'

   Part of a larger effort to move the Rust code over to the 'sync'
   module.

 - Make CONFIG_LSM dependent on CONFIG_SECURITY

   As the CONFIG_LSM Kconfig setting is an ordered list of the LSMs to
   enable a boot, it obviously doesn't make much sense to enable this
   when CONFIG_SECURITY is disabled.

 - Update the LSM and CREDENTIALS sections in MAINTAINERS with Rusty
   bits

   Add the Rust helper files to the associated LSM and CREDENTIALS
   entries int the MAINTAINERS file. We're trying to improve the
   communication between the two groups and making sure we're all aware
   of what is going on via cross-posting to the relevant lists is a good
   way to start.

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 reStructuredText 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.
