urngd: add micro non-physical true RNG based on timing jitter
μrngd is OpenWrt's micro non-physical true random number generator based on timing jitter. Using the Jitter RNG core, the rngd provides an entropy source that feeds into the Linux /dev/random device if its entropy runs low. It updates the /dev/random entropy estimator such that the newly provided entropy unblocks /dev/random. The seeding of /dev/random also ensures that /dev/urandom benefits from entropy. Especially during boot time, when the entropy of Linux is low, the Jitter RNGd provides a source of sufficient entropy. Acked-by: Jo-Philip Wich <jow@mein.io> Tested-by: Lucian Cristian <lucian.cristian@gmail.com> Signed-off-by: Petr Štetiar <ynezz@true.cz> (cherry picked from commit 714bd89fceee494282984d0ed76e4a3acde419e0)
