Namely these commits: commit b95744ba0ac2f46a95ecbe423a4d8dd7c9513da0 Author: Oliver Pinter <oliver.pinter@hardenedbsd.org> Date: Sun Oct 15 17:15:48 2017 +0200 opBSD MFC r324394: random(4): Gather entropy from Pure sources At initialization, hc_source_mask only includes non-Pure sources. The patch changes source registration to enable the registered source in the hc_source_mask bitmask. This mask governs which sources are harvested. This patch also disallows userspace from disabling such sources. PR: 222807 Submitted by: W.

Only feed in the relatively high entropy counter and explicit entropy buffer to increase measured input entropy.
