* Add bool param to ALERT_KEEP_ON_CHILD_SA_FAILURE alertAdrian-Ken Rueegsegger2015-05-042-3/+8
| | | | | The parameter indicates if the alert is raised upon failure to establish the first CHILD SA of an IKE SA.
* vici: Default to certificate subject for identityTimo Teräs2015-05-041-0/+37
| | | | | | | | If id is not specified and certificate authentication is used, use the certificate subject name as identity. Simplifies configuration as in most cases this is the right thing to do. Signed-off-by: Timo Teräs <timo.teras@iki.fi>
* vici: Add support for ike_sa and child_sa updown notificationsTimo Teräs2015-05-043-0/+137
| | | | | | Useful for monitoring and management purposes. Signed-off-by: Timo Teräs <timo.teras@iki.fi>
* vici: Add function to test if an event should be generatedTimo Teräs2015-05-042-0/+74
| | | | | | | Useful to avoid generating vici messages if they are not needed and their generation is heavy operation. Signed-off-by: Timo Teräs <timo.teras@iki.fi>
* ike-vendor: Add some Microsoft vendor IDsTobias Brunner2015-04-211-0/+10

* vici: Relicense libvici.h under MITMartin Willi2015-04-141-9/+20
| | | | | | libvici currently relies on libstrongswan, and therefore is bound to the GPLv2. But to allow alternatively licensed reimplementations without copyleft based on the same interface, we liberate the header.

* vici: Defer read/write error reporting after connection entry has been releasedMartin Willi2015-04-131-12/+34
| | | | | | | | | | | | | | | | If a vici client registered for (control-)log events, but a vici read/write operation fails, this may result in a deadlock. The attempt to write to the bus results in a vici log message, which in turn tries to acquire the lock for the entry currently held. While a recursive lock could help as well for a single thread, there is still a risk of inter-thread races if there is more than one thread listening for events and/or having read/write errors. We instead log to a local buffer, and write to the bus not before the connection entry has been released. Additionally, we mark the connection entry as unusable to avoid writing to the failed socket again, potentially triggering an error loop.
* aead: Create AEAD using traditional transforms with an explicit IV generatorMartin Willi2015-04-131-4/+11
| | | | | | Real AEADs directly provide a suitable IV generator, but traditional crypters do not. For some (stream) ciphers, we should use sequential IVs, for which we pass an appropriate generator to the AEAD wrapper.
* stroke: Properly parse bliss key strength in public key constraintTobias Brunner2015-03-251-1/+1

* child-sa: Add a new state to track rekeyed IKEv1 CHILD_SAsTobias Brunner2015-03-257-5/+15
| | | | | | This is needed to handle DELETEs properly, which was previously done via CHILD_REKEYING, which we don't use anymore since 5c6a62ceb6 as it prevents reauthentication.
* ikev1: Inverse check when applying received KE value during Quick Mode5.3.0rc1Martin Willi2015-03-241-1/+1
| | | | Fixes Quick Mode negotiation when PFS is in use.
* encoding: Remove DH public value verification from KE payloadMartin Willi2015-03-231-73/+0
| | | | | | | | This commit reverts 84738b1a and 2ed5f569. As we have no DH group available in the KE payload for IKEv1, the verification can't work in that stage. Instead, we now verify DH groups in the DH backends, which works for any IKE version or any other purpose.
* diffie-hellman: Add a bool return value to set_other_public_value()Martin Willi2015-03-235-7/+55
|
* diffie-hellman: Add a bool return value to get_my_public_value()Martin Willi2015-03-238-12/+39
|
* encoding: Allow ke_payload_create_from_diffie_hellman() to failMartin Willi2015-03-235-13/+59
|
* diffie-hellman: Use bool instead of status_t as get_shared_secret() return valueMartin Willi2015-03-236-10/+10
| | | | | While such a change is not unproblematic, keeping status_t makes the API inconsistent once we introduce return values for the public value operations.
* load-tester: Migrate NULL DH implementation to INIT/METHOD macrosMartin Willi2015-03-231-21/+26

* ikev1: Make sure SPIs in an IKEv1 DELETE payload match the current SATobias Brunner2015-03-231-0/+39
| | | | | | | | | | | | | | | | | | | | OpenBSD's isakmpd uses the latest ISAKMP SA to delete other expired SAs. This caused strongSwan to delete e.g. a rekeyed SA even though isakmpd meant to delete the old one. What isakmpd does might not be standard compliant. As RFC 2408 puts it: Deletion which is concerned with an ISAKMP SA will contain a Protocol-Id of ISAKMP and the SPIs are the initiator and responder cookies from the ISAKMP Header. This could either be interpreted as "copy the SPIs from the ISAKMP header of the current message to the DELETE payload" (which is what strongSwan assumed, and the direction IKEv2 took it, by not sending SPIs for IKE), or as clarification that ISAKMP "cookies" are actually the SPIs meant to be put in the payload (but that any ISAKMP SA may be deleted).
* encoding: Add getter for IKE SPIs in IKEv1 DELETE payloadsTobias Brunner2015-03-232-0/+25
|
* trap-manager: Add option to ignore traffic selectors from acquire eventsTobias Brunner2015-03-231-1/+8
| | | | | | | | The specific traffic selectors from the acquire events, which are derived from the triggering packet, are usually prepended to those from the config. Some implementations might not be able to handle these properly. References #860.
* encoding: Don't verify length of IKEv1 KE payloadsTobias Brunner2015-03-201-0/+6
| | | | | | The verification introduced with 84738b1aed95 ("encoding: Verify the length of KE payload data for known groups") can't be done for IKEv1 as the KE payload does not contain the DH group.
* attr-sql: Rename sql_attribute_t to attr_sql_provider_tMartin Willi2015-03-195-32/+32
| | | | | | As the plugin has its origins in the sql plugin, it still uses the naming scheme for the attribute provider implementation. Rename the class to better match the naming scheme we use in any other plugin
* ikev1: Adopt virtual IPs on new IKE_SA during re-authenticationTobias Brunner2015-03-193-45/+156
| | | | | | | | | | | Some clients like iOS/Mac OS X don't do a mode config exchange on the new SA during re-authentication. If we don't adopt the previous virtual IP Quick Mode rekeying will later fail. If a client does do Mode Config we directly reassign the VIPs we migrated from the old SA, without querying the attributes framework. Fixes #807, #810.
* ikev1: Mark rekeyed CHILD_SAs as INSTALLEDTobias Brunner2015-03-191-0/+2
| | | | | Since we keep them around until they finally expire they otherwise would block IKE_SA rekeying/reauthentication.
* mem-pool: Remove entries without online or offline leasesTobias Brunner2015-03-191-6/+22
| | | | | | This avoids filling up the hash table with unused/old identities. References #841.
* kernel-handler: Log new endpoint if NAT mapping changedTobias Brunner2015-03-191-2/+3

* vici: Fall back to heap buffer when vararg printing on stack failsMartin Willi2015-03-181-21/+44
| | | | This avoids failures when building log event messages including larger hexdumps.
* vici: Return a Python generator instead of a list for streamed responsesMartin Willi2015-03-182-47/+25
| | | | | | | In addition that it may reduce memory usage and improve performance for large responses, it returns immediate results. This is important for longer lasting commands, such as initiate/terminate, where immediate log feedback is preferable when interactively calling such commands.
* vici: Raise a Python CommandException instead of returning a CommandResultMartin Willi2015-03-182-82/+42

* vici: Add initial Python egg documentation to READMEMartin Willi2015-03-181-0/+65
|
* vici: Use OrderedDict to handle vici responses in Python libraryMartin Willi2015-03-181-2/+3
| | | | | The default Python dictionaries are unordered, but order is important for some vici trees (for example the order of authentication rounds).
* vici: Return authentication rounds with unique namesMartin Willi2015-03-181-1/+4
| | | | | | To simplify handling of authentication rounds in dictionaries/hashtables on the client side, we assign unique names to each authentication round when listing connection.
* vici: Rebuild ruby gem on source file changesMartin Willi2015-03-181-1/+1
|
* vici: Use default Unix vici socket if none passed to ruby constructorMartin Willi2015-03-182-4/+7
| | | | | While we currently have a static path instead of one generated with Autotools, this at least is congruent to what we have in the Python library.
* vici: Support non-Unix sockets for vici connections using PythonMartin Willi2015-03-182-7/+9
|
* vici: Add python egg setuptools building and installation using easy_installMartin Willi2015-03-181-0/+15
| | | | | | An uninstall target is currently not supported, as there is no trivial way with either plain setuptools or with easy_install. pip would probably be the best choice, but we currently don't depend on it.
