I'm surprised to see all the commentary about GnuPG and OpenSSL reading from /dev/random.

OpenSSL has traditionally read from /dev/urandom and for over a year now, GnuPG has been reading from the getrandom syscall even for key generation.

I also noticed it and felt it was unwarranted and showed not a small amount of hubris. Blaming developers for using a kernel facility that was made available to them is deflecting the problem. Ironically so, because it was the kernel (via ext4) that caused a blocking regression (DOS?) and started this work.

This patch set actually predates the ext4 issue.
