Comment (by midnightmagic):
Hi zooko,
Yes, it is very reproducible, and it is exactly as reproducible as the
error message from cryptest.exe test program from crypto++. :-( It's not a
bug in the kernel though, unless you consider blocking on /dev/random to
be a bug. I'm not sure I do.
Further steps to reproduce are:
. TURN OFF all entropy sources via rndctl
. ACTIVELY DRAIN /dev/random by cat /dev/random > /dev/null
. WATCH to ensure that there are 0 bytes of entropy in the pool via rndctl
. (Optional) Build a bunch of other stuff that uses /dev/random during
their test suites
