Subject: random: fix output buffer folding
From: Matt Mackall <mpm@xxxxxxxxxxx>
(As reported by linux@xxxxxxxxxxx)
Folding is done to minimize the theoretical possibility of systematic
weakness in the particular bits of the SHA1 hash output. The result of
this bug is that 16 out of 80 bits are un-folded. Without a major new
vulnerability being found in SHA1, this is harmless, but still worth
fixing.
