Subject: ctnetlink unique id size?
Date: Thu, 17 Feb 2005 18:41:49 +0100 [thread overview]
Message-ID: <4214D75D.5070005@ingate.com> (raw)
Hi,
isn't an unsigned int a bit (or rather about 32 bits) small for
keeping the id field of the ip_conntrack struct? It's bound to wrap
around, and with things like long-lived ssh sessions it's even
possible for two connections to be assigned the same id after a
wrap-around.
Am I missing something obvious when I think ctnetlink_dump_table()
will break down when the wrap-around occurs?
Using an uint64_t would on the other hand guarantee that each
connection really get a unique id.
