config INTEGRITY
def_bool y
depends on IMA || EVM
config INTEGRITY_SIGNATURE
boolean "Digital signature verification using multiple keyrings"
depends on INTEGRITY && 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_AUDIT
bool "Enables integrity auditing support "
depends on INTEGRITY && 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.
config INTEGRITY_ASYMMETRIC_KEYS
boolean "Enable asymmetric keys support"
depends on INTEGRITY_SIGNATURE
default n
select ASYMMETRIC_KEY_TYPE
select ASYMMETRIC_PUBLIC_KEY_SUBTYPE
select PUBLIC_KEY_ALGO_RSA
select X509_CERTIFICATE_PARSER
help
This option enables digital signature verification using
asymmetric keys.
