| |
From: Arnd Bergmann <arnd@arndb.de>
When CONFIG_SYSTEM_BLACKLIST_KEYRING and CONFIG_INTEGRITY_PLATFORM_KEYRING are both enabled, the system blacklist tries calling the pkcs7_validate_trust() function, causing a link failure if the driver that defines it is disabled or a loadable module:
ld.lld: error: undefined symbol: pkcs7_validate_trust >>> referenced by blacklist.c >>> blacklist.o:(is_key_on_revocation_list) in archive certs/built-in.a
Add a Kconfig 'select' statement for this specific case that force- enables the pkcs7 code as well.
