Thanks for the comments. I made the modification and attached the latest
copy. Now it uses ip_ct_refresh. The target first reads the existing expire
value, then modify it. If there is something in between, the expire value
might get changed. Even worse, the conntrack state might change. That's why
I locked it first, then read and write, finally unlock. If it is broken,
there is no difference anyway...
