Merge tag 'integrity-v6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/zohar/linux-integrity
Pull integrity updates from Mimi Zohar:
- Add a new IMA/EVM maintainer and reviewer
- Disable EVM on overlayfs
The EVM HMAC and the original file signatures contain filesystem
specific metadata (e.g. i_ino, i_generation and s_uuid), preventing
the security.evm xattr from directly being copied up to the overlay.
Further before calculating and writing out the overlay file's EVM
HMAC, EVM must first verify the existing backing file's
'security.evm' value.
For now until a solution is developed, disable EVM on overlayfs.
- One bug fix and two cleanups
* tag 'integrity-v6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/zohar/linux-integrity:

MAINTAINERS: Add Eric Snowberg as a reviewer to IMA
MAINTAINERS: Add Roberto Sassu as co-maintainer to IMA and EVM
KEYS: encrypted: Add check for strsep
ima: Remove EXPERIMENTAL from Kconfig
ima: Reword IMA_KEYRINGS_PERMIT_SIGNED_BY_BUILTIN_OR_SECONDARY
