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.
