Re: [PATCH] Kernel entropy rework

[Taylor R Campbell <riastradh%NetBSD.org@localhost>]

I guess I should have included a single unified diff rather than just
a git format-patch set.  From a CVS tree, the attached
entropy-unified.patch can be applied with

cd /path/to/src && patch -p1 < /path/to/entropy-unified.patch

(And from a git tree, you can apply the patch set in the original
email with `git am < /path/to/entropy.git'.)


Some background, from a cryptographer, on the historical system of
entropy `estimation' and `depletion' which has been essentially
unchanged in Linux and NetBSD since it was introduced in the 1990s,
and which I'm proposing to change now to better reflect modern
cryptography:
