Andreas Steffen 1d315bddd3 implemented the right|leftallowany feature 2012-06-08 21:24:41 +02:00
Martin Willi e5f0f9ff96 Enforce uniqueness policy in IKEv1 main and aggressive modes 2012-06-08 16:15:22 +02:00
Tobias Brunner 4a10eda1a0 starter: Go back to single threaded mode. 
Mixing multiple threads and fork(2) wasn't a very good idea it seems.
At least in some environments this caused strange side-effects.

Tobias Brunner 05ca56558c Disabled listening for kernel events in starter. 2012-06-08 14:12:06 +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 106b938b6b Store shorter soft lifetime of in- and outbound SAs only 2012-06-08 10:22:03 +02:00
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.

Tobias Brunner 89c97952bd starter: Changed signal handling now that starter is multi-threaded. 2012-06-04 18:09:56 +02:00
Tobias Brunner c8f7a114b6 Mark CHILD_SAs used for trap policies to uninstall them properly. 
If the installation failed the state is not CHILD_ROUTED which means the
wrong priority is used to uninstall the policies.  This is a problem for
kernel interfaces that keep track of installed policies as now the proper
policy is not found (if the priority is considered).

Tobias Brunner 79d5c4f06b Fixed return values of several functions (e.g. return FALSE for pointer types). 2012-05-31 17:39:04 +02:00

Tobias Brunner 60c82591c5 Retry IKE_SA initiation if DNS resolution failed. 
This is disabled by default and can be enabled with the
charon.retry_initiate_interval option in strongswan.conf.
 2012-05-30 15:32:52 +02:00
Tobias Brunner eac9d77059 Job added to re-initiate an IKE_SA. 2012-05-30 15:32:52 +02:00
Tobias Brunner 53915f14ae Fix MOBIKE address update if responder address changed. 
Use the source address of the current MOBIKE message as peer address
instead of assuming the address cached on the IKE_SA is still valid.
 2012-05-25 17:05:53 +02:00
Tobias Brunner a46fe56858 Resolve hosts before reauthenticating due to address change. 2012-05-25 17:05:53 +02:00
Tobias Brunner c6da59f014 Don't queue delete_ike_sa job when setting IKE_DELETING. 
This avoids deleting IKE_SAs during reauthentication (without
trying to reestablish them).
 2012-05-25 17:05:53 +02:00
Tobias Brunner 7457143072 During reauthentication reestablish IKE_SA even if deleting the old one fails. 2012-05-25 17:05:53 +02:00

Tobias Brunner 00e11bcefd Fix memleak during Quick Mode in case no SPI can be allocated from kernel. 2012-05-24 15:32:27 +02:00
Tobias Brunner 624bb24d12 Properly filter IKEv1 proposals consisting of multiple proposal payloads. 
Since a proposal_t object is created for each transform contained in the
proposal payload, it does not work to simply remove the last proposal_t
object added to the list (there may be several other extracted from the
previous proposal payload).
 2012-05-24 15:32:27 +02:00
Tobias Brunner fda9f104b4 Fixed check for loaded plugins with feature types that are not compared exactly.
