commit 88e70da170e8 ("IMA: Define an IMA hook to measure keys") in next-integrity added an IMA hook to measure keys when they are created or updated in the system. This hook is defined in ima_asymmetric_keys.c which was built if CONFIG_ASYMMETRIC_PUBLIC_KEY_SUBTYPE was defined. But this config is a tristate (and not a bool type). If CONFIG_ASYMMETRIC_PUBLIC_KEY_SUBTYPE was set to "m" in the .config, ima_asymmetric_keys.c was built as a kernel module when it is not a kernel module. This issue was reported by "kbuild test robot <lkp@intel.com>".
This change defines a new config namely CONFIG_IMA_MEASURE_ASYMMETRIC_KEYS to enable building ima_asymmetric_keys.c. This new config is enabled when both CONFIG_IMA and CONFIG_ASYMMETRIC_PUBLIC_KEY_SUBTYPE are defined.
Lakshmi Ramasubramanian (4): IMA: Define an IMA hook to measure keys KEYS: Call the IMA hook to measure keys IMA: Add support to limit measuring keys IMA: Read keyrings= option from the IMA policy
