9 13:24:06 2024 -0800 # # 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: # overlay: disable EVM # evm: add support to disable EVM on unsupported filesystems # evm: don't copy up 'security.evm' xattr # 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 #
