Subject: [PATCH v2 2/2] crypto: drbg: DRBG_CTR should select CTR
Date: Tue, 10 Mar 2020 21:05:38 +0000 [thread overview]

if CRYPTO_DRBG_CTR is builtin and CTR is module, allocating such algo
will fail.
DRBG: could not allocate CTR cipher TFM handle: ctr(aes)

Since setting DRBG_CTR=CTR lead to a recursive dependency, let's depends
on CTR=y
Just selecting CTR lead also to a recursive dependency:
crypto/Kconfig:1800:error: recursive dependency detected!
crypto/Kconfig:1800: symbol CRYPTO_DRBG_MENU is selected by
CRYPTO_RNG_DEFAULT
crypto/Kconfig:83: symbol CRYPTO_RNG_DEFAULT is selected by
CRYPTO_SEQIV
crypto/Kconfig:330: symbol CRYPTO_SEQIV is selected by CRYPTO_CTR
crypto/Kconfig:370: symbol CRYPTO_CTR is selected by CRYPTO_DRBG_CTR
crypto/Kconfig:1822: symbol CRYPTO_DRBG_CTR depends on
CRYPTO_DRBG_MENU
