LARTC - Jan 2006 - conntrack event/hook when ''expected'' connection terminates ?

Hello,

I need to understand how conntrack_core.c handles the termination
of ''expected'' connection; handling in the case when
''expected''
connection arrived, then terminates (In my conntrack module, 
I need to specially handle the event of termination termination 
of ''expected'' connection.)

In ip_conntrack_core.c, I can''t find the call chain of deallocation
of ''expectation'' after termination of
''expected'' connection.
Deallocation must happen somewhere, but I don''t see any hooks 
related to termination of ''expected'' connection.

Or maybe the termination of expected connection is not detected at all, 
but handled via expiring timer ? Can anyone confirm or correct this ?

So my question is how is termination of expected connection handled
by conntrack code. Thanks

Yakov Lerner
