* unit-tests: Actually verify registered algorithms against test vectorsTobias Brunner2014-03-202-5/+47
| | | | | | | | Previously, the {ns}.crypto_test.on_add option had to be enabled to actually test the algorithms, which we can't enforce for the tests in the test_runner as the option is already read when the crypto factory is initialized. Even so, we wouldn't want to do this for every unit test, which would be the result of enabling that option.
* unit-tests: Use TEST_FUNCTION macro in ntru testsTobias Brunner2014-03-201-34/+44
|
* unit-tests: Implement registered functions without __builtin_apply()Tobias Brunner2014-03-201-17/+17
| | | | | This makes the tests work with clang, which does not implement said builtin.
* unit-tests: Call functions with TEST_ prefix in ntru testTobias Brunner2014-03-201-36/+38
|
* unit-tests: Prefix imported testable functions with TEST_Tobias Brunner2014-03-201-3/+3
| | | | This avoids any clashes with existing functions in the monolithic build.
* unit-tests: Change how hashtable for testable functions is createdTobias Brunner2014-03-203-28/+49
| | | | | | | | Because GCC does not adhere to the priorities defined for constructors when building with --enable-monolithic (not sure if it was just luck that it worked in non-monolithic mode - anyway, it's not very portable) function registration would fail because the hashtable would not be created yet.
* unit-tests: Generate weak keys with gcrypt plugin (but quickly)Tobias Brunner2014-03-201-0/+3
|
* plugin-feature: Hash only the actually used feature argumentTobias Brunner2014-03-201-1/+31
| | | | | | | | Clang does not initialize padding in union members so hashing the complete "arg" union could lead to different hashes if the hashed plugin_feature_t does not have static storage duration. Fixes #549.
* array: Fix removal of elements in the second half of an arrayTobias Brunner2014-03-181-1/+1
| | | | | | | Memory beyond the end of the array was moved when array elements in the second half of an array were removed. Fixes #548.

| | | | Closes #539.
* settings: Avoid conf file parsing beyond allocated bufferThomas Egerer2014-03-031-2/+2
| | | | | | | | | | | | | | | A valgrind analysis of libstrongswan revealed an invalid read of 1 in the function starts_with(). A more thorough analysis proved this to be true and showed that with a specially crafted config file (e.g. a single '#'-character not followed by a newline), the parser might even interpret the random memory contents following the allocated buffer as part of the configuration file. The way the parser is designed, it must be able to skip an inserted '\0' and continue parsing. Since it is not able to skip two '\0' characters, the 'fix' of allocating two more bytes than the size of the parsed file and setting them to '\0' seems to be a safe bet.

* utils: Add memrchr(3) replacement for platforms that don't support itTobias Brunner2014-02-263-1/+81
| | | | For instance, on Mac OS X memrchr(3) is not provided by the C library.
* settings: Use thread-safe dirname(3)Tobias Brunner2014-02-241-5/+3

* utils: Add thread-safe variants of dirname(3) and basename(3)Tobias Brunner2014-02-243-4/+144
|
* utils: Move thread-safe strerror replacement to a separate fileTobias Brunner2014-02-247-99/+145
| | | | | For some utils _GNU_SOURCE might be needed but that conflicts with the signature of strerror_r(3).
* settings: Use dirname(3) correctlyTobias Brunner2014-02-241-4/+4
| | | | | | | | dirname(3) may return a pointer to a statically allocated buffer. So freeing the returned value can result to undefined behavior. This was noticed on FreeBSD where it caused very strange crashes. It is also not thread-safe, which will be addressed later.

* lookip: Disconnect asynchronously to avoid dead-locking watcher unregistrationMartin Willi2014-02-171-3/+2
| | | | | | | | | While it really would be desirable to allow stream destruction during on_read() callbacks, this does not work anymore since e49b2998. Until we have a proper solution for this issue, use asynchronous disconnects for the only user doing so. Fixes #518.
* Fixed a minor vulnerability in which a malformed ASN.1 length field could ↵5.1.2rc1Andreas Steffen2014-02-141-0/+1

|
* settings: Implement subsections and key/value pairs with sorted arraysTobias Brunner2014-02-121-68/+74
| | | | | | Is a bit more memory efficient (also due to lazy instantiation) and lookups for sections with lots of subsections/keys (e.g. charon.plugins) are faster.
* array: Add fallback for qsort_r using thread-local valueTobias Brunner2014-02-123-2/+49
| | | | Cygwin for example does not support qsort_r.
* plugin-loader: Optionally use load option in each plugin section to load pluginsTobias Brunner2014-02-122-4/+144
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This now works because all plugins use the same config namespace. If <ns>.load_modular is true, the list of plugins to load is determined via the value of the <ns>.plugins.<name>.load options. Using includes the following is possible: charon { load_modular = yes plugins { include strongswan.d/charon/*.conf } } charon-cmd { load_modular = yes plugins { include strongswan.d/charon-cmd/*.conf } } Where each .conf file would contain something like: <name> { load = yes <option> = <value> } To increase the priority of individual plugins load = <priority> can be used (the default is 1). For instance, to use openssl instead of the built-in crypto plugins set in strongswan.d/charon/openssl.conf: openssl { load = 10 } If two plugins have the same priority their order in the default plugin list is preserved. Plugins not found in that list are ordered alphabetically before other plugins with the same priority.

|
* settings: Add method that allows to define fallback sections for other sectionsTobias Brunner2014-02-123-13/+276
| | | | | The fallbacks are currently only used for single value lookups. Enumerators are not affected by them.
* settings: Make print_key() not rely on null-terminated beginning of key bufferTobias Brunner2014-02-121-10/+5
| | | | | The key to print (e.g. until the next .) still has to be null-terminated.
