Martin Willi 271377905d Defer quick mode initiation if we expect a mode config request 2012-06-27 11:42:56 +02:00
Martin Willi 2d4c347af9 While checking for redundant quick modes, compare traffic selectors 
If a configuration is instanced more than once using narrowing,
we should keep all unique quick modes up during rekeying.

Martin Willi 7a5f372c57 Initiate quick mode rekeying with narrowed traffic selectors 2012-06-08 10:22:03 +02:00
Martin Willi 1e24fa4614 Instead of rekeying, delete a quick mode if we have a fresher instance 
If both peers initiate quick mode rekeying simultaneously, we end up
with duplicate SAs for a configuration. This can't be avoided, nor do
the standards provide an appropriate solution. Instead of closing one
SA immediately, we keep both. But once rekeying triggers, we don't
refresh the SA with the shorter soft lifetime, but delete it.
