* eap-radius: Keep track of stats for SAs migrated during IKEv1 reauthenticationTobias Brunner2015-05-211-88/+229
|
* eap-radius: Remove cache entries for expired SAs during ike/child_rekeyTobias Brunner2015-05-211-0/+53
|
* eap-radius: Add cache for usage stats of expired/rekeyed SAsTobias Brunner2015-05-211-6/+102
| | | | | | | | | | | | | There are several situations that the previous code didn't handle that well, for example, interim updates during rekeying (until the rekeyed SA was deleted the numbers were too high, then suddenly dropped afterwards), or rekeying for IKEv1 in general because rekeyed IPsec SAs stay installed until they expire (so if they were still around when the IKE_SA was terminated, the reported numbers in the Stop message were too high). If intermediate updates are not used the cache entries for rekeyed CHILD_SA will accumulate, we can't clean them up as we don't get child_updown() events for them.
* 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>
* 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.
* utils: Use chunk_equals_const() for all cryptographic purposesMartin Willi2015-04-144-7/+5

* 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.
* stroke: Properly parse bliss key strength in public key constraintTobias Brunner2015-03-251-1/+1
|
* eap-tnc: Free eap-tnc object if IKE_SA not found to get IPsTobias Brunner2015-03-251-0/+1
|
* Fixed some typos, courtesy of codespellTobias Brunner2015-03-251-1/+1
|
* child-sa: Add a new state to track rekeyed IKEv1 CHILD_SAsTobias Brunner2015-03-252-2/+4
| | | | | | 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.
* diffie-hellman: Add a bool return value to set_other_public_value()Martin Willi2015-03-231-1/+2
|
* diffie-hellman: Add a bool return value to get_my_public_value()Martin Willi2015-03-233-5/+9
|
* diffie-hellman: Use bool instead of status_t as get_shared_secret() return valueMartin Willi2015-03-234-6/+6
| | | | | 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
|
* 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
* vici: Add support for python 3Björn Schuberg2015-03-185-8/+29

* vici: Execute python tests during "check" if py.test is availableMartin Willi2015-03-181-0/+4

* vici: Evaluate Python streamed command results, and raise CommandExceptionMartin Willi2015-03-181-1/+10
|
* vici: Catch Python GeneratorExit to properly cancel streamed event iterationMartin Willi2015-03-182-1/+12
|
* 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.
* vici: Generate a version specific setup.py for setuptools installationMartin Willi2015-03-183-0/+41

* vici: Use %u to print stats returned by mallinfo(3)Tobias Brunner2015-03-131-4/+4
| | | | Fixes #886.
* stroke: Use %u to print stats returned by mallinfo(3)Tobias Brunner2015-03-131-1/+1
| | | | References #886.
* eap-radius: Increase Acct-Session-ID string bufferMartin Willi2015-03-131-1/+1
| | | | | | | | As the startup timestamp needs 10 characters, we only have left 4 characters for the IKE_SA unique identifier. This is insufficient when having 10000 IKE_SAs or more established, resulting in non-unique session identifiers. Fixes #889.
* ha: Destroy synced IKE_SA if no configuration is found during updateMartin Willi2015-03-101-0/+3
|
* libipsec: Pass separate inbound/update flags to the IPsec SA managerMartin Willi2015-03-091-1/+2
| | | | | Similar to other kernel interfaces, the libipsec backends uses the flag for different purposes, and therefore should get separate flags.
* kernel-interface: Add a separate "update" flag to add_sa()Martin Willi2015-03-093-3/+3
| | | | | | | | | | | The current "inbound" flag is used for two purposes: To define the actual direction of the SA, but also to determine the operation used for SA installation. If an SPI has been allocated, an update operation is required instead of an add. While the inbound flag normally defines the kind of operation required, this is not necessarily true in all cases. On the HA passive node, we install inbound SAs without prior SPI allocation.
* Revert "ha: Always install the CHILD_SAs with the inbound flag set to FALSE"Martin Willi2015-03-091-2/+2
| | | | | | | | While this change results in the correct add/update flag during installation, it exchanges all other values in the child_sa->install() call. We should pass the correct flag, but determine the add/update flag by other means. This reverts commit e722ee5d.
* Make access requestor IP address available to TNC serverAndreas Steffen2015-03-082-12/+39
