Having read the various articles following the CERT advisory, I think that
if I understand correctly, the fix to tcp_init_seq isn't quite correct.
If the clock is warped backwards by settimeofday(), it will be possible
(albeit unlikely) for sequence numbers to be reused.
Would it be better for jiffies * constant to be used as the base, with
the usec added as the jitter?
