"...it remains unclear if these attacks lead to actual exploitable
vulnerabilities
in practice."
in my mtrngd for XSTORE i not only fed /dev/random when it became
write-able (entropy less than full) but also fed it at regular
intervals, specifically to keep the pool fresh.
in the standard rng-tools rngd, you specify this parameter with the
timeout parameter,
"Interval written to random-device when the entropy pool is full, in
seconds (default: 60)"
i am pleased to see this made it into the stock rngd source!
best regards,
