Is this because EVM is bool and kconfig is confused about 'select's when a bool is selecting tristates? Shouldn't the tristates become 'y' instead of 'm' if they are selected by a bool that is 'y'? xconfig shows these symbol values: Symbol: EVM [=y] Type : boolean Prompt: EVM support Defined at security/integrity/evm/Kconfig:1 Depends on: SECURITY [=y] && KEYS [=y] && TCG_TPM [=m] Location: -> Security options Selects: CRYPTO_HMAC [=m] && CRYPTO_MD5 [=m] && CRYPTO_SHA1 [=m] && CRYPTO_HASH2 [=m] && ENCRYPTED_KEYS [=m] && TRUSTED_KEYS [=m] Hm, changing TCG_TPM to =y also changes TRUSTED_KEYS and ENCRYPTED_KEYS and lots of CRYPTO_ symbols from =m to =y. There must be some kind of min/max symbol checking that is confused? --- ~Randy *** Remember to use Documentation/SubmitChecklist when testing your code ***
