From 6cb33c62c8007593d8a85aa202fa173043877135 Mon Sep 17 00:00:00 2001 From: Pablo Neira Ayuso Date: Thu, 7 Aug 2008 14:53:12 +0200 Subject: cache iterators: rework cache_reset_timers This patch adds the clause PurgeTimeout that sets the new timer when conntrackd -t is called. This command is particularly useful when the sysadmin triggers hand-overs between several nodes without rebooting as it reduces the timers of the remaining entries in the kernel. Thus, avoiding clashes between new and old entries that may trigger INVALID packets.
