getrandom waits for a long time when /dev/random is insufficiently read from
...the urandom pool has
been replaced by an actual CSPRNG using the ChaCha-20 stream cipher.
The getrandom(2) system call uses the same output pool (4.7 and
earlier) or CSPRG (starting with v4.8-rc1) as /dev/urandom. The big
difference is that it blocks until we know for sure that the output
pool or CSRPNG has been seeded with 128 bits of entropy. We don't do
this with /dev/urandom for backwards compatibility reasons. (For
example, if we did make /dev/urandom block until it was seeded, it
would break systemd, because systemd and progams run by systemd draws
from /dev/urandom before it has been...
