* vici: Certification Authority support added.Andreas Steffen2015-07-219-11/+937
| | | | | | CDP and OCSP URIs for a one or multiple certification authorities can be added via the VICI interface. swanctl allows to read definitions from a new authorities section.

* vici: Asynchronize debug loggingMartin Willi2015-07-121-1/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The vici logger uses the listener_t.log() callback to raise vici events. When doing so, it holds the bus lock as reader while acquiring the vici socket mutex (1). If at the same time the vici socket enables a writer, that thread tries to lock the watcher mutex (2). The watcher thread uses debugging while holding the lock, i.e. acquires the bus read lock (3). (1) bus.rlock -> vici.lock! (2) vici.lock -> watcher.lock! (3) watcher.lock -> bus.rlock! This all actually would resolve just fine, as we have a shared read lock on the bus. However, under Windows we seem to have a strict writer preference when acquiring the rwlock (4). This results in blocking read locks until any pending write lock can be fulfilled, and makes the constellation deadlock.

It's actually never good practice to acquire shared locks during bus hooks, as it is problematic if we raise bus events while holding the lock. We do so by raising vici events for log message asynchronously, but of curse must keep log order as is using a synchronized queue.

* ha: Move plugin initialization from constructor to plugin callbackTobias Brunner2015-05-261-58/+69
| | | | | This fixes support for the secret option, as otherwise the kernel interface is not registered yet when the trap policy is installed.
* vici: Explicitly disable --user-install when installing Ruby GemTobias Brunner2015-05-211-1/+1
| | | | | | | | Only one of `--user-install` and `--install-dir` may be set and if `--user-install` is the default on a system installation will fail unless we disable it explicitly. Fixes #914.
* vici: Make installation of Ruby Gem and Python Egg optionalTobias Brunner2015-05-212-0/+4
| | | | | | | | | | | | | | | | | | Installing them might not work well when building distro packages (e.g. with DESTDIR installs). It might be easier to install them later with a script in the distro package. When building from source on the local system it could still be useful to install the packages directly, which can be enabled with separate configure options. The main problem with DESTDIR installations of the Python Egg is that easy_install creates or modifies a file called easy-install.pth in the installation directory. So it's not actually possible to simply copy the results in DESTDIR over to the actual system as that file would have to be merged with any existing one. Fixes #914.
* vici: Support out-of-tree build of Python EggTobias Brunner2015-05-211-5/+5
| | | | | | | We also don't require setup.py to exist during cleanup, as e.g. with make distcheck the source directory is not writable when the build directory is cleaned, so setup.py can't be created (to just get removed again anyway if VICI and the Python Eggs haven't been enabled previously).
* 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.

* 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.

* 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: 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: 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: 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: 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.
