The bulk of the motivation for this and description of crypto
vulnerabilities is in the first patch of this series. The following two
patches then fix up entropy accounting for the new model. The last patch
fixes a minor code safety issue.

This v2 improves some documentation comments and unifies these patches
into one patchset.

Jason A. Donenfeld (4):
  random: use computational hash for entropy extraction
  random: simplify entropy debiting
  random: use linear min-entropy accumulation crediting
  random: make credit_entropy_bits() always safe
