* eap-sim-file: Remove redundant enumerator allocationTobias Brunner2017-05-261-1/+1
|
* sql: Remove redundant enumerator allocationTobias Brunner2017-05-261-1/+1
| | | | | | Interestingly, this doesn't show up in the regression tests because the compiler removes the first assignment (and thus the allocation) due to -O2 that's included in our default CFLAGS.

* linked-list: Change return value of find_first() and signature of its callbackTobias Brunner2017-05-2629-397/+525
| | | | This avoids the unportable five pointer hack.
* linked-list: Change interface of callback for invoke_function()Tobias Brunner2017-05-269-54/+98
| | | | This avoids the unportable five pointer hack.
* linked-list: invoke_offset() doesn't take any additional arguments anymoreTobias Brunner2017-05-263-18/+16
|
* Change interface for enumerator_create_filter() callbackTobias Brunner2017-05-2650-929/+1331
| | | | | This avoids the unportable 5 pointer hack, but requires enumerating in the callback.
* Migrate all enumerators to venumerate() interface changeTobias Brunner2017-05-2668-560/+851
|
* enumerator: Add venumerate() method to enumerator_t that takes a va_listTobias Brunner2017-05-262-8/+51
| | | | | | | | | | This will allow us to implement e.g. enumerator_cleaner without having to use that unportable 5 pointer forwarding or having to define a callback for each instance. A generic implementation for enumerate() is provided so only venumerate() has to be implemented, which may be simplified by using the VA_ARGS_VGET() macro.

* child-cfg: Optionally use 96-bit truncation for HMAC-SHA-256Tobias Brunner2017-05-262-0/+11
| | | | | | | | The correct truncation is 128-bit but some implementations insist on using 96-bit truncation. With strongSwan this can be negotiated using an algorithm identifier from a private range. But this doesn't work with third-party implementations. This adds an option to use 96-bit truncation even if the official identifier is used.

* child-delete: Delay the removal of the inbound SA of rekeyed CHILD_SAsTobias Brunner2017-05-233-128/+412
| | | | | | | | After deleting a rekeyed CHILD_SA we uninstall the outbound SA but don't destroy the CHILD_SA (and the inbound SA) immediately. We delay it a few seconds or until the SA expires to allow delayed packets to get processed. The CHILD_SA remains in state CHILD_DELETING until it finally gets destroyed.
* delete-child-sa-job: Add new constructor that takes the unique ID of a CHILD_SATobias Brunner2017-05-232-13/+69
| | | | | This makes sure we delete the right SA in case the addresses got updated in the mean time.
* child-sa: Remove state to track installation of half the SA againTobias Brunner2017-05-236-62/+47
|
* unit-tests: Overload helper macro to check for outbound SA stateTobias Brunner2017-05-231-2/+30

* child-sa: Expose state of the outbound SATobias Brunner2017-05-232-17/+61

* child-sa: Add method to remove the outbound SA and policiesTobias Brunner2017-05-232-5/+78
|
* child-sa: Keep track whether the outbound SA has been installed or notTobias Brunner2017-05-231-8/+13

* child-delete: Track flags per individual CHILD_SATobias Brunner2017-05-231-47/+78
|
* ikev2: Delay installation of outbound SAs during rekeying on the responderTobias Brunner2017-05-234-30/+124
| | | | | | | | The responder has all the information needed to install both SAs before the initiator does. So if the responder immediately installs the outbound SA it might send packets using the new SA which the initiator is not yet able to process. This can be avoided by delaying the installation of the outbound SA until the replaced SA is deleted.
* child-sa: Add log message for CHILD_SA state changesTobias Brunner2017-05-231-0/+4
|
* child-sa: Add method to associate rekeyed CHILD_SAs with their replacementTobias Brunner2017-05-232-0/+35
|
* child-sa: Add methods that allow partial installation of CHILD_SATobias Brunner2017-05-232-5/+144
| | | | | | | Using install() for the inbound SA and register_outbound() for the outbound SA followed by install_policies(), will delay the installation of the outbound SA as well as the installation of the outbound policies in the kernel until install_outbound() is called later.
* child-sa: Add new state to track installation of only the inbound SATobias Brunner2017-05-232-1/+7
|
* child-sa: Change API used to set/install policiesTobias Brunner2017-05-236-79/+119
| | | | This way we only have to pass the traffic selectors once.
* child-sa: Split in- and outbound policy de-/installationTobias Brunner2017-05-231-62/+127
| | | | Only install outbound fallback policies.
* child-create: Trigger NARROW_RESPONDER_POST hook before installing SAsTobias Brunner2017-05-231-25/+21
| | | | | This makes sure we use the same set of traffic selectors when installing the SAs and installing the policies.
* tnc-ifmap: Null-terminate buffer to make sscanf()-calls safeTobias Brunner2017-05-231-4/+5

* libimcv: Make sure the first argument to sscanf() is null-terminatedTobias Brunner2017-05-232-2/+6

* asn1: Make sure the first argument to sscanf() is null-terminatedTobias Brunner2017-05-231-7/+9

* x509: Fix leak when parsing CDPs if an invalid one follows valid onesTobias Brunner2017-05-231-2/+2

* pem: Ensure a value before checking Proc-Type in PEM headerTobias Brunner2017-05-231-1/+1
|
* chunk: Correctly parse Base64 text where four = follow in a rowTobias Brunner2017-05-231-1/+1
| | | | | | | That's not correct Base64 but invalid data could trigger this. Since outlen would get reduced four times, but is only ever increased three times per iteration, this could result in an integer underflow and then a potential buffer overflow.
* plugin-loader: Disable some logging output when building fuzz targetsTobias Brunner2017-05-231-4/+19
| | | | | This avoids evaluating %N. An alternative would be to define a printf-hook for plugin features.
* x509: Manually print CRL/OCSP URIs when fuzzingTobias Brunner2017-05-231-8/+25
| | | | This avoids a warning about the custom %Y printf specifier.
* processor: Move priority threads assignment to set_threads()Tobias Brunner2017-05-231-4/+9
| | | | | | This avoids the evaluation of %N even if the thread pool is never used. We need to avoid as many custom printf specifiers as possible when fuzzing our code to avoid excessive log messages.
* Add plugin constructor registration for all libraries that provide pluginsTobias Brunner2017-05-238-0/+64
| | | | | | | | | | | | | | Unfortunately, we can't just add the generated C file to the sources in Makefile.am as the linker would remove that object file when it notices that no symbol in it is ever referenced. So we include it in the file that contains the library initialization, which will definitely be referenced by the executable. This allows building an almost stand-alone static version of e.g. charon when building with `--enable-monolithic --enable-static --disable-shared` (without `--disable-shared` libtool will only build a version that links the libraries dynamically). External libraries (e.g. gmp or openssl) are not linked statically this way, though.
* plugin-constructors: Add script to generate constructor registrationTobias Brunner2017-05-232-0/+61
| | | | Using a Python script so this works in cross-compilation situations.
* plugin-loader: Add facility to register plugin constructorsTobias Brunner2017-05-232-3/+69
| | | | | | | | | | | | | | Enabled when building monolithically and statically. This should allow us to work around the -whole-archive issue with libtool. If the libraries register the plugin constructors they provide they reference the constructors and will therefore prevent the linker from removing these seemingly unused symbols from the final executable. For use cases where dlsym() can be used, e.g. because the static libraries are manually linked with -whole-archive (Linux) or -force-load (Apple), this can be disabled by passing ss_cv_static_plugin_constructors=no to the configure script.
