There seems to be a small bug in inet_connection_sock.c: the lowest port
set using sysctl (taken from 'sysctl_local_port_range') is always
skipped in the first iteration.
In inet_csk_get_port one can find this:
if (hashinfo->port_rover < low)
rover = low;
rover = hashinfo->port_rover;
do {
As you can see the first statement is a ++ causing the first port to
always be skipped.

This has already been fixed three weeks ago by Stephen Hemminger's port
randomization patch.
