| H A D | fortuna.c | diff 345981 Sat Apr 06 09:05:10 MDT 2019 markm Backport fixes from FreeBSD-12 to help the random(4) device thread not overwhelm the OS: a) Use the correct symbolic constant when calculating 10'ths of a second. This means that expensive reseeds happen at ony 1/10 Hz, not some kHz. b) Rate limit internal high-rate harveting efforts. This stops the harvesting thread from total overkilling the high-grade entropy- gathering work, while still being very conservatively safe.
