[PATCH] IMA: add INTEGRITY_ASYMMETRIC_KEYS dependency

Show all headers | View raw

The newly added CONFIG_IMA_KEYRINGS_PERMIT_SIGNED_BY_BUILTIN_OR_SECONDARY
option only makes sense in combination with INTEGRITY_ASYMMETRIC_KEYS,
otherwise we get a build error:

warning: (IMA_KEYRINGS_PERMIT_SIGNED_BY_BUILTIN_OR_SECONDARY) selects INTEGRITY_TRUSTED_KEYRING which has unmet direct dependencies (INTEGRITY && SYSTEM_TRUSTED_KEYRING && INTEGRITY_ASYMMETRIC_KEYS)
security/integrity/evm/evm_main.c: In function 'evm_load_x509':
security/integrity/evm/evm_main.c:494:7: error: implicit declaration of function 'integrity_load_x509'
  rc = integrity_load_x509(INTEGRITY_KEYRING_EVM, CONFIG_EVM_X509_PATH);

This adds a Kconfig dependency.
