Subject: [PATCH v27 07/12] LRNG - add kernel crypto API PRNG extension
Date: Thu, 09 Jan 2020 09:33:25 +0100
Message-ID: <2586090.d86fZevfFX@positron.chronox.de> (raw)
In-Reply-To: <2641155.iNH938UiKq@positron.chronox.de>

Add runtime-pluggable support for all PRNGs that are accessible via
the kernel crypto API, including hardware PRNGs. The PRNG is selected
with the module parameter drng_name where the name must be one that the
kernel crypto API can resolve into an RNG.

This allows using of the kernel crypto API PRNG implementations that
provide an interface to hardware PRNGs. Using this extension,
the LRNG uses the hardware PRNGs to generate random numbers. An
example is the S390 CPACF support providing such a PRNG.

The hash is provided by a kernel crypto API SHASH whose digest size
complies with the seedsize of the PRNG.
