* ikev2: Delay online revocation checks during make-before-break reauthenticationTobias Brunner2016-03-101-0/+5
| | | | | | | | | | | | | | | | | | | | | We do these checks after the SA is fully established. When establishing an SA the responder is always able to install the CHILD_SA created with the IKE_SA before the initiator can do so. During make-before-break reauthentication this could cause traffic sent by the responder to get dropped if the installation of the SA on the initiator is delayed e.g. by OCSP/CRL checks. In particular, if the OCSP/CRL URIs are reachable via IPsec tunnel (e.g. with rightsubnet=0.0.0.0/0) the initiator is unable to reach them during make-before-break reauthentication as it wouldn't be able to decrypt the response that the responder sends using the new CHILD_SA. By delaying the revocation checks until the make-before-break reauthentication is completed we avoid the problems described above. Since this only affects reauthentication, not the original IKE_SA, and the delay until the checks are performed is usually not that long this doesn't impose much of a reduction in the overall security.
* ikev2: Add task that verifies a peer's certificateTobias Brunner2016-03-107-2/+183
| | | | | | On failure the SA is deleted and reestablished as configured. The task is activated after the REAUTH_COMPLETE task so a make-before-break reauth is completed before the new SA might get torn down.

| | | | | | | | | | enumerator We already do this in the trusted public key enumerator (which internally uses the trusted certificate enumerator) but should do so also when this enumerator is used directly (since the public key enumerator has the read lock the additional call will just be skipped there).

* charon-svc: Inherit all settings from the charon sectionTobias Brunner2016-03-081-0/+9
| | | | Same as with charon-systemd.
* charon-systemd: Inherit all settings from the charon sectionTobias Brunner2016-03-081-0/+9
| | | | | | | | Our default config files are very charon specific. So to avoid confusion when only charon-systemd is installed we just default to all settings defined for charon. Since charon-systemd probably won't be used together with charon this should not cause conflicts (settings may still be overridden via the charon-systemd section).
* library: Add option to register additional namespaces before calling ↵Tobias Brunner2016-03-082-2/+43
| | | | | | | | | | library_init() Because settings are already accessed in library_init(), calling add_fallback() externally after calling library_init() is not ideal. This way namespaces already serve as fallback while library_init() is executed and they are also in the correct order so that libstrongswan is always the last root section.
* vici: Replace child configs atomicallyTobias Brunner2016-03-081-14/+11

| | | | | | | Some implementations might otherwise not recognize the NAT-D payload type. Also moves SIG and HASH payloads last in these messages. Fixes #1239.

| | | | This is a feature currently supported by stroke.
* auth-cfg: Make IKE signature schemes configurableTobias Brunner2016-03-047-42/+194
| | | | | | This also restores the charon.signature_authentication_constraints functionality, that is, if no explicit IKE signature schemes are configured we apply all regular signature constraints as IKE constraints.
* ikev2: Always store signature scheme in auth-cfgTobias Brunner2016-03-041-12/+1
| | | | As we use a different rule we can always store the scheme.
* ikev2: Diversify signature scheme ruleThomas Egerer2016-03-044-33/+72

* ike-init: Verify REDIRECT notify before processing IKE_SA_INIT messageTobias Brunner2016-03-041-7/+51
| | | | | | An attacker could blindly send a message with invalid nonce data (or none at all) to DoS an initiator if we just destroy the SA. To prevent this we ignore the message and wait for the one by the correct responder.

* task: Add optional pre_process() methodTobias Brunner2016-03-041-1/+13
| | | | | This will eventually allow tasks to pre-process and verify received messages.
* ike-init: Ignore notifies related to redirects during rekeyingTobias Brunner2016-03-041-3/+13

|
* ike-sa: Reauthenticate to the same addresses we currently useTobias Brunner2016-03-041-2/+5
| | | | | | If the SA got redirected this would otherwise cause a reauthentication with the original gateway. Reestablishing the SA to the original gateway, if e.g. the new gateway is not reachable makes sense though.
* vici: Don't redirect all SAs if no selectors are givenTobias Brunner2016-03-041-1/+1
| | | | | This avoid confusion and redirecting all SAs can now easily be done explicitly (e.g. peer_ip=0.0.0.0/0).
