* 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.

* Merge branch 'dh-test-vectors'Martin Willi2015-04-1533-79/+1806
|\ | | | | | | | | Add a Diffie-Hellman backend test method, a set of test vectors and implement testing of the gmp, openssl and gcrypt DH backend.
| * kernel-netlink: Don't mangle verbosity during test initializationMartin Willi2015-04-151-2/+0
| | | | | | | | | | We now properly manage thread verbosity in the test framework, and don't need to silence thread spawning messages.
| * 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.
| * travis: Run a gcrypt test with leak-detectiveMartin Willi2015-04-152-5/+1
| | | | | | | | And also enable gcrypt in the all tests with leak-detective enabled.
| * 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.

| * diffie-hellman: Introduce an optional setter for the private valueMartin Willi2015-04-151-0/+12
|/ | | | This allows us to work with deterministic values for testing purposes.
* Merge branch 'aesni'Martin Willi2015-04-1532-104/+5891
|\ | | | | | | | | Add an aesni plugin providing CBC, CTR, XCBC, CMAC, CCM and GCM modes for for AES-128/192/256 based on AES-NI/PCLMULQDQ intrinsics.
| * NEWS: Add aesni plugin newsMartin Willi2015-04-151-0/+6

| * aesni: Avoid loading AES/GHASH round keys into local variablesMartin Willi2015-04-156-1568/+1244
| | | | | | | | | | | | | | | | | | | | The performance impact is not measurable, as the compiler loads these variables in xmm registers in unrolled loops anyway. However, we avoid loading these sensitive keys onto the stack. This happens for larger key schedules, where the register count is insufficient. If that key material is not on the stack, we can avoid to wipe it explicitly after crypto operations.
| * aesni: Align all class instances to 16 byte boundariesMartin Willi2015-04-157-14/+14
| | | | | | | | | | | | While the required members are aligned in the struct as required, on 32-bit platforms the allocator aligns the structures itself to 8 bytes only. This results in non-aligned struct members, and invalid memory accesses.
| * utils: Provide aligning variants of INIT/INIT_EXTRA macrosMartin Willi2015-04-151-0/+29
| |
| * unit-tests: Pass stringyfied assertion statement as non-format string argumentMartin Willi2015-04-151-3/+3
| | | | | | | | | | | | If the assertion contains a modulo (%) operation, test_fail_msg() handles this as printf() format specifier. Pass the assertion string as argument for an explicit "%s" in the format string, instead.
| * utils: Add malloc/free wrappers returning aligned dataMartin Willi2015-04-153-0/+101
| | | | | | | | | | | | | | | | | | | | | | | | | | While we could use posix_memalign(3), that is not fully portable. Further, it might be difficult on some platforms to properly catch it in leak-detective, which results in invalid free()s when releasing such memory. We instead use a simple wrapper, which allocates larger data, and saves the padding size in the allocated header. This requires that memory is released using a dedicated function. To reduce the risk of invalid free() when working on corrupted data, we fill up all the padding with the padding length, and verify it during free_align().
| * aesni: Calculate GHASH for 4 blocks of associated data in parallelMartin Willi2015-04-151-2/+18
| | | | | | | | | | While associated data is usually not that large, in some specific cases this can bring a significant performance boost.
| * aesni: Calculate GHASH for 4 blocks of encryption data in parallelMartin Willi2015-04-151-40/+180
| | | | | | | | Increases performance by another ~30%.
| * aesni: Use 4-way parallel en/decryption in GCMMartin Willi2015-04-151-132/+635
| | | | | | | | Increases overall performance by ~25%.
| * aesni: Use dedicated key size specific en-/decryption functions in GCMMartin Willi2015-04-151-24/+353
| | | | | | | | | | This gives not much more than ~5% increase in performance, but allows us to improve further.
| * aesni: Add a GCM AEAD based on the AES-NI key scheduleMartin Willi2015-04-154-1/+627
| |
| * aesni: Implement CMAC mode to provide a signer/prfMartin Willi2015-04-154-0/+441
| | | | | | | | | | Compared to the cmac plugin using AESNI-CBC as backend, this improves performance of AES-CMAC by ~45%.
| * aesni: Implement XCBC mode to provide a signer/prfMartin Willi2015-04-154-0/+436
| | | | | | | | | | Compared to the xcbc plugin using AESNI-CBC as backend, this improves performance of AES-XCBC by ~45%.
