* vici: flush-certs command flushes certificate cacheAndreas Steffen2016-09-136-0/+68
| | | | | | | | | | When fresh CRLs are released with a high update frequency (e.g. every 24 hours) or OCSP is used then the certificate cache gets quickly filled with stale CRLs or OCSP responses. The new VICI flush-certs command allows to flush e.g. cached CRLs or OCSP responses only. Without the type argument all kind of certificates (e.g. also received end entity and intermediate CA certificates) are purged.
* ikev2: (Re-)Queue tasks used to establish an IKE_SA in reset()Tobias Brunner2016-09-061-2/+1
| | | | | | | | | Some tasks might get removed immediately once the IKE_SA_INIT response has been handled even if there were notifies that require a restart of the IKE_SA (e.g. COOKIE or INVALID_KE_PAYLOAD). Such a task is ike_vendor, which caused vendor IDs not to get sent in a retry. This change ensures all required tasks are queued after the reset, which some callers did already anyway.

* ikev1: Ignore the last two bytes of the Cisco Unity vendor IDTobias Brunner2016-08-241-0/+3
| | | | | | | | | These seem to indicate the major and minor version of the protocol, like e.g. for the DPD vendor ID. Some implementations seem to send versions other than 1.0 so we just ignore these for now when checking for known vendor IDs. Fixes #2088.

* ike1: Flush active queue when queueing a delete of the IKE_SATobias Brunner2016-07-191-0/+3
| | | | | | | | | | | By aborting the active task we don't have to wait for potential retransmits if the other peer does not respond to the current task. Since IKEv1 has no sequential message IDs and INFORMATIONALs are no real exchanges this should not be a problem. Fixes #1537 References #429, #1410 Closes strongswan/strongswan#48

* child-rekey: Only rekey installed CHILD_SAsTobias Brunner2016-06-171-7/+14
| | | | | | | | | | | | Depending on the lifetimes a CHILD_SA we rekeyed as responder might expire shortly afterwards. We don't want to rekey it again. When retrying due to an INVALID_KE_PAYLOAD notify the expected state is CHILD_REKEYING if it is anything else (e.g. due to a collision) we ignore it. We also abort the exchange properly if we don't find the CHILD_SA, no need for an empty INFORMATIONAL exchange anymore.

* child-rekey: Ignore failed colliding CHILD_SA rekeyingsTobias Brunner2016-06-171-1/+10
| | | | | | | If a passive rekeying fails due to an INVALID_KE_PAYLOAD we don't want to consider this task later when resolving collisions. This previously might have caused the wrong SA to get deleted/installed based on the nonces in the unsuccessful exchange.

* ikev2: Add possibility to delay initiation of a queued taskTobias Brunner2016-06-175-66/+189
| | | | | | | | | | | Such a task is not initiated unless a certain time has passed. This allows delaying certain tasks but avoids problems if we'd do this via a scheduled job (e.g. if the IKE_SA is rekeyed in the meantime). If the IKE_SA is rekeyed the delay of such tasks is reset when the tasks are adopted i.e. they get executed immediately on the new IKE_SA. This hasn't been implemented for IKEv1 yet.

* ike-rekey: Handle undetected collisions also if delete is delayedTobias Brunner2016-06-171-16/+26
| | | | | | | | | | | If the peer does not detect the rekey collision and deletes the old IKE_SA and then receives the colliding rekey request it will respond with TEMPORARY_FAILURE. That notify may arrive before the DELETE does, in which case we may just conclude the rekeying initiated by the peer. Also, since the IKE_SA is destroyed in any case when we receive a delete there is no point in storing the delete task in collide() as process_i() in the ike-rekey task will never be called.
* ike-rekey: There is no passive reauth task, so it will never collide with oneTobias Brunner2016-06-172-7/+4
|
* ike-rekey: Ignore colliding rekey tasks that did not create an IKE_SATobias Brunner2016-06-171-56/+64
| | | | | This simplifies collision handling and we don't need to know about these tasks when concluding the rekeying we initiated.
* ike-rekey: Properly handle situation if the peer did not notice the rekey ↵Tobias Brunner2016-06-171-0/+11
| | | | | | | | | | collision We conclude the rekeying before deleting the IKE_SA. Waiting for the potential TEMPORARY_FAILURE notify is no good because if that response does not reach us the peer will not retransmit it upon our retransmits of the rekey request if it already deleted the IKE_SA after receiving our response to the delete.
* ike-delete: Handle deletes while rekeying differently if there was a collisionTobias Brunner2016-06-171-2/+40
| | | | | We treat these as if we concluded the rekeying, the active ike-rekey task will handle the collision afterwards.
