Subject: [PATCH v29 03/12] LRNG - sysctls and /proc interface
Date: Sun, 19 Jan 2020 22:14:03 +0100
Message-ID: <5278006.UvChaxsJ5D@positron.chronox.de> (raw)
In-Reply-To: <1967138.dxe05VgvIB@positron.chronox.de>

The LRNG sysctl interface provides the same controls as the existing
/dev/random implementation. These sysctls behave identically and are
implemented identically. The goal is to allow a possible merge of the
existing /dev/random implementation with this implementation which
implies that this patch tries have a very close similarity. Yet, all
sysctls are documented at [1].

In addition, it provides the file lrng_type which provides details about
the LRNG:

- the name of the DRNG that produces the random numbers for /dev/random,
/dev/urandom, getrandom(2)

- the hash used to produce random numbers from the entropy pool

- the number of secondary DRNG instances

- indicator whether the LRNG operates SP800-90B compliant

- indicator whether a high-resolution timer is identified - only with a
high-resolution timer the interrupt noise source will deliver sufficient
entropy

- indicator whether the LRNG has been minimally seeded (i.e. is the
secondary DRNG seeded with at least 128 bits of of entropy)

- indicator whether the LRNG has been fully seeded (i.e. is the
secondary DRNG seeded with at least 256 bits of entropy)
