From: Arnd Bergmann <arnd@xxxxxxxx> The selftest code is built into the x509_key_parser module, and depends on the pkcs7_message_parser module, which in turn has a dependency on the key parser, creating a dependency loop and a resulting link failure when the pkcs7 code is a loadable module: ld: crypto/asymmetric_keys/selftest.o: in function `fips_signature_selftest': crypto/asymmetric_keys/selftest.c:205: undefined reference to `pkcs7_parse_message' ld: crypto/asymmetric_keys/selftest.c:209: undefined reference to `pkcs7_supply_detached_data' ld: crypto/asymmetric_keys/selftest.c:211: undefined reference to `pkcs7_verify' ld: crypto/asymmetric_keys/selftest.c:215: undefined reference to `pkcs7_validate_trust' ld: crypto/asymmetric_keys/selftest.c:219: undefined reference to `pkcs7_free_message' Avoid this by only allowing the selftest to be enabled when either both parts are loadable modules, or both are built-in.
