# SPDX-License-Identifier: GPL-2.0-only#config INTEGRITY	bool "Integrity subsystem"	depends on SECURITY	default y	help	  This option enables the integrity subsystem, which is comprised	  of a number of different components including the Integrity	  Measurement Architecture (IMA), Extended Verification Module	  (EVM), IMA-appraisal extension, digital signature verification	  extension and audit measurement log support. 	  Each of these components can be enabled/disabled separately.	  Refer to the individual components for additional details. if INTEGRITY config INTEGRITY_SIGNATURE	bool "Digital signature verification using multiple keyrings"	default n	select KEYS	select SIGNATURE	help	  This option enables digital signature verification support	  using multiple keyrings. It defines separate keyrings for each	  of the different use cases - evm, ima, and modules.	  Different keyrings improves search performance, but also allow	  to "lock" certain keyring to prevent adding new keys.	  This is useful for evm and module keyrings, when keys are	  usually only added from initramfs. config INTEGRITY_ASYMMETRIC_KEYS	bool "Enable asymmetric keys support"	depends on INTEGRITY_SIGNATURE	default n	select ASYMMETRIC_KEY_TYPE	select ASYMMETRIC_PUBLIC_KEY_SUBTYPE	select CRYPTO	select CRYPTO_RSA	select X509_CERTIFICATE_PARSER	help	  This option enables digital signature verification using	  asymmetric keys. config INTEGRITY_TRUSTED_KEYRING	bool "Require all keys on the integrity keyrings be signed"	depends on SYSTEM_TRUSTED_KEYRING	depends on INTEGRITY_ASYMMETRIC_KEYS	default y	help	   This option requires that all keys added to the .ima and	   .evm keyrings be signed by a key on the system trusted	   keyring. config INTEGRITY_PLATFORM_KEYRING	bool "Provide keyring for platform/firmware trusted keys"	depends on INTEGRITY_ASYMMETRIC_KEYS	depends on SYSTEM_BLACKLIST_KEYRING	help	  Provide a separate, distinct keyring for platform trusted keys, which	  the kernel automatically populates during initialization from values	  provided by the platform for verifying the kexec'ed kerned image	  and, possibly, the initramfs signature. config INTEGRITY_MACHINE_KEYRING	bool "Provide a keyring to which Machine Owner Keys may be added"	depends on SECONDARY_TRUSTED_KEYRING	depends on INTEGRITY_ASYMMETRIC_KEYS	depends on SYSTEM_BLACKLIST_KEYRING	depends on LOAD_UEFI_KEYS || LOAD_PPC_KEYS	help	  If set, provide a keyring to which Machine Owner Keys (MOK) may	  be added.

By default no restrictions are in place	  and all Machine Owner Keys (MOK) are added to the machine keyring.	  If enabled only CA keys are added to the machine keyring, all	  other MOK keys load into the platform keyring. config INTEGRITY_CA_MACHINE_KEYRING_MAX	bool "Only CA keys without DigitialSignature usage set"	depends on INTEGRITY_CA_MACHINE_KEYRING	default n	help	  When selected, only load CA keys are loaded into the machine	  keyring that contain the CA bit set along with the keyCertSign	  Usage field.  Keys containing the digitialSignature Usage field	  will not be loaded.
