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.
