Martin Willi e5f0f9ff96 Enforce uniqueness policy in IKEv1 main and aggressive modes 2012-06-08 16:15:22 +02:00
Martin Willi 82ad53b776 Try to rekey without KE exchange if peer returns INVALID_KE_PAYLOAD(NONE) 
According to RFC5996, implementations should just ignore the KE payload
if they select a non-PFS proposals. Some implementations don't, but
return MODP_NONE in INVALID_KE_PAYLOAD, hence we accept that, too.

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 d61f2906d4 Use traffic selectors passed to quick mode constructor as initiator 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.

Martin Willi 1b7debcc04 Keep COOKIEs enabled once threshold is hit, until we see no COOKIEs for a few secs 
Toggling COOKIEs on/off is problematic: After doing a COOKIE exchange as
initiator, we can't know if the completing IKE_SA_INIT message is to our first
request or the one with the COOKIE. If the responder just enabled/disabled
COOKIEs and packets get retransmitted, both might be true. Avoiding COOKIE
behavior toggling improves the situation, but does not solve the problem during
the initial COOKIE activation.
