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"
depends on KEYS
default n
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_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_AUDIT
bool "Enables integrity auditing support "
depends on AUDIT
default y
help
In addition to enabling integrity auditing support, this
option adds a kernel parameter 'integrity_audit', which
controls the level of integrity auditing messages.
0 - basic integrity auditing messages (default)
1 - additional integrity auditing messages
Additional informational integrity auditing messages would
be enabled by specifying 'integrity_audit=1' on the kernel
command line.
