Thanks Eric!
So /proc/sys/net/ipv4/ip_local_reserved_ports is a production knob, and
if we wanted to stress test it with a selftest it could break othe
Here's a pretty hacky test script to test this code via
ip_local_reserved_ports
-
#!/bin/bash
# Randomly construct well-formed (sequential, non-overlapping)
# input for ip_local_reserved_ports, feed it to the sysctl,
# then read it back and check for differences.
# Port range to use
PORT_ST
