FYI, something in here broke the wireguard test suite, which runs the
iperf3 networking utility. The full log is here [1], but the relevant part
is: 

[+] NS1: iperf3 -Z -t 3 -c 192.168.241.2
Connecting to host 192.168.241.2, port 5201
iperf3: error - failed to read /dev/urandom: Bad address

I'll see if I can narrow it down a bit more and bisect. But just FYI, in
case you have an intuition.

Jason
