The check to see if TCP port allocation should change from random to sequential port allocation mode may incorrectly cause a false positive due to negative wraparound. Example: V_ipport_tcpallocs = 2147483585 (0x7fffffc1) V_ipport_tcplastcount = 2147483553 (0x7fffffa1) V_ipport_randomcps = 100 The original code would compare (2147483585 <= -2147483643) and thus incorrectly move to sequential allocation mode. Compute the delta first before comparing against the desired limit to limit the wraparound effect (since tcplastcount is always a snapshot of a previous tcpallocs).
