* proposal: Add a chacha20poly1305 proposal keywordMartin Willi2015-06-291-0/+1

* crypter: Define a ChaCha20/Poly1305 AEAD algorithm identifierMartin Willi2015-06-293-3/+7

* capabilities: Handle ERANGE in user and group lookupsTobias Brunner2015-06-231-12/+48
| | | | | | | | | | | | | | As it turns out, getpwnam_r, getgrnam_r, and friends will return ERANGE if _any_ user or group on the system is larger than will fit into the scratch buffer you pass to them. This reworks the resolve_uid and resolve_gid methods plus init_supplementary_groups to use a variable-size buffer that is grown until the results fit. Based on a patch by Evan Broder. Closes strongswan/strongswan#12.
* Remove accidentally added stamp-h1Tobias Brunner2015-06-151-1/+0
| | | | Was added in bc4748832395 ("Add a return value to prf_t.get_bytes()").
* settings: Fix out-of-tree buildTobias Brunner2015-06-111-1/+1
| | | | | The header file was created in the source directory before, where it wasn't found by the generated C files in the build directory.
* unit-tests: Add tests for iv_gen_seq_tTobias Brunner2015-06-053-0/+75
|
* ivgen: Allow reusing the same message ID twice in sequential IV genMartin Willi2015-06-051-7/+25
| | | | | | | | | | | | We use the message ID and fragment number as IV generator. As IKEv2 uses distinct message ID counters for actively and passively initiated exchanges, each IV would be used twice. As we explicitly reject such message IDs since d0ed1079, original-responder initiated exchanges fail with counter mode ciphers. This commit separates IV space in two halves for sequential IVs, and automatically assigns once reused sequence numbers to the second half. Fixes #980.
* iv-gen: Fail getting shorter IV values than the used counter sizeMartin Willi2015-06-011-0/+4
| | | | | While no algorithm actually uses such short IVs, we add a check here to ensure we won't return just the lower bits of the counter.
* iv-gen: Ensure external sequential IVs are actually sequentialMartin Willi2015-06-012-0/+23
| | | | We allow gaps in IVs, but ensure that an IV is never used more than once.
* leak-detective: Use passed callback to report leaksTobias Brunner2015-04-201-2/+2
| | | | | | | | This prevented `stroke memusage` from reporting the leaks on the console. Instead, they were sent to the callbacks set up by libstrongswan. Fixes a426851f6362 ("leak-detective: Use callback functions to report leaks and usage information").
* openssl: Don't refer to EVP_des_ecb() if OpenSSL is built without DES supportTobias Brunner2015-04-171-0/+2
| | | | | | While DES-ECB is not registered by the plugin in this case (so the function will never actually be called), the compiler still warns about the implicitly declared function.

|
* unit-tests: Further increase the test vector testing timeoutMartin Willi2015-04-161-1/+1
| | | | Some build bots running make check seem to have longer for the DH testing.
* test-vectors: Define test vector symbols as externMartin Willi2015-04-161-7/+7
| | | | | | We don't actually define a vector, but only prototype the test vector implemented in a different file. GCC uses the correct symbol during testing, but clang correctly complains about duplicated symbols during linking.
* aesni: Fix doxygen groupsMartin Willi2015-04-151-2/+2
|
* unit-tests: Set test verbosity just after test suite loadingMartin Willi2015-04-151-10/+9
| | | | | | We see any plugin startup messages during suite configuration, where initialization is called once to query plugin features. No need to be verbose and show these messages once again in the first test.
* crypto-factory: Remove obsolete transform testing functionsMartin Willi2015-04-152-54/+0
|
* unit-tests: Use progressive testing of transforms with test vectorsMartin Willi2015-04-151-7/+26
| | | | | | This allows us to show which transform from which plugin failed. Also, we use the new cleanup handler functionality that allows proper deinitialization on failure or timeout.
* transform: Add a getter for the enum_names for a specific transform typeMartin Willi2015-04-152-0/+40
|
* enum-names: Fail gracefully when passing a NULL value as enum namesMartin Willi2015-04-152-1/+15
|
* crypto-factory: Add enumerator method to support individual transform testingMartin Willi2015-04-152-0/+127
|
* unit-tests: Invoke all registered thread cleanup handlers on test failureMartin Willi2015-04-151-0/+3
| | | | | | | | | | | If a test fails in a timeout or a test failure, longjmp() is used to restore the thread context and handle test failure. However, there might be unreleased resources, namely locks, which prevent the library to clean up properly after finishing the test. By using thread cleanup handlers, we can release any test subject internal or test specific external resources on test failure. We do so by calling all registered cleanup handlers.
* thread: Add a function to pop and call all registered cleanup handlersMartin Willi2015-04-154-0/+78
|
* thread: Don't acquire lock for thread_cleanup_push/popMartin Willi2015-04-151-5/+0
| | | | | This is called only by the thread for its own thread_t, and does not need synchronization.
* gcrypt: Explicitly initialize RNG backend to allocate static dataMartin Willi2015-04-151-0/+3
| | | | | | The libgcrypt RNG implementation uses static buffer allocation which it does not free. There is no symbol we can catch in leak-detective, hence we explicitly initialize the RNG during the whitelisted gcrypt_plugin_create() function.
* leak-detective: Whitelist gcrypt_plugin_create()Martin Willi2015-04-151-0/+1
| | | | | | gcry_check_version() does not free statically allocated resources. However, we can't whitelist it in some versions, as it is not a resolvable symbol name. Instead, whitelist our own plugin constructor function.
* unit-tests: Add a TESTS_PLUGINS environment variableMartin Willi2015-04-152-1/+6
| | | | This is often more convenient than specifying plugins in a configuration file.
* unit-tests: Use a larger timeout for test vector testingMartin Willi2015-04-151-0/+1
| | | | | As we test DH calculations this now takes more time. If multiple DH backends are enabled, we likely hit the default test timeout.
* gcrypt: Support setting private value and testing of DH backendMartin Willi2015-04-151-0/+19
|
* openssl: Support setting ECDH private valuesMartin Willi2015-04-151-0/+44
