Hi Kirill,

> +	select CRYPTO_ANSI_CPRNG

This change enables the RNG which will not pass FIPS testing any more. Hence, 
this selection could cause an issue in FIPS mode (i.e. booting the kernel with 
fips=1).

May I suggest CRYPTO_DRBG?

Ciao
Stephan

Hello Ciao,

Thanks for your proposal. I submitted the PATCH v2 where I use
CRYPTO_RNG_DEFAULT the same way it is used in crypto/Kconfig.
It solves the issue, too. In addition, it selects CRYPTO_DRBG_MENU,
which is a more universal use-case, as I understood from your comment.

Best Regards,
Kirill
