* Disable Sonar buildJack Lloyd2018-11-171-5/+5
| | | | | | | | | | | | It is suddenly 5x slower for an unknown reason https://community.sonarsource.com/t/sonar-analysis-step-suddenly-much-5x-slower-on-travis-ci/4364 Now it either times out or else completely dominates the runtime for Travis, either is not acceptable. Leave the framework for using Sonar in CI for now so it is easy to test if things have improved later. If things are still broken in a month or two I'll probably just drop support for Sonar.

* Attempt to fix Sonar build problemJack Lloyd2018-11-172-1/+8
| | | | | | The build is timing out. Use -Os instead of -O3 in an attempt to speed up the build step, and enable multithreaded analysis as that step is also quite slow.
* Use vzeroupper/vzeroall to transition between AVX and SSE states.Jack Lloyd2018-11-104-0/+32
| | | | | | | | Otherwise some CPUs suffer serious stalls. Using vzeroall on exit also has the nice effect that we don't have to worry about register contents leaking. HT to @noloader for doing the background research on this.
* Avoid an implausible integer overflow flagged by Coverity [ci skip]Jack Lloyd2018-11-101-1/+6

* Avoid branching in the NIST prime reduction codeJack Lloyd2018-11-092-59/+58
| | | | | This is still vulnerable to a cache-based side channel since the multiple chosen leaks the final carry.

|\
| * Optimize mod_subJack Lloyd2018-11-091-10/+21
| | | | | | | | | | We already assumed the args are < modulus so we can avoid the call to sig_words. This provides a noticable speedup for ECDSA overall.
| * Add a cache of sig words to BigIntJack Lloyd2018-11-093-97/+232

* | Run RSA blinding tests only with base providerAlexander Bluhm2018-11-081-2/+9
|/ | | | | Only the base provider uses blinding for RSA. So the test should run exclusively for this provider. Also use base provider explicitly.
* Add some missing includesJack Lloyd2018-11-088-0/+9
| | | | This is not exhaustive. See GH #1733
* Switch LibreSSL provider to OpenSSL 1.1 APIAlexander Bluhm2018-11-073-6/+6
| | | | | | | LibreSSL 2.7 has added parts of the OpenSSL 1.1 API. Remove the defined(LIBRESSL_VERSION_NUMBER) as it is not necessary anymore. Switch to the newer API unconditionally, older LibreSSL version are not supported.
* Compile fixJack Lloyd2018-11-072-1/+2

* Avoid throwing std:: exceptionsJack Lloyd2018-11-073-2/+3
| | | | | Also include <new> in mem_ops.cpp as apparently that header is where bad_alloc is defined.

* Add missing <stdexcept> <string> necessaryLarry-Hu2018-11-072-2/+2
|
* Simplify BigInt::is_zeroJack Lloyd2018-11-061-6/+1
| | | | | | The definition of return value of sig_words() means the integer is zero iff sig_words() returns zero, so there is no reason to scan over the data twice.

| * Optimize AVX2 ChaChaJack Lloyd2018-11-052-238/+209
| | | | | | | | | | | | Using the same transposition trick used for SSE2 in #1728 On my Skylake desktop about 5-10% faster depending on buffer sizes.

* / Remove SIMD_32 typedefJack Lloyd2018-11-054-50/+48
|/ | | | | It is confusing since its not clear from the name how many elements it has, and this gives consistency with SIMD_8x32 type.
* Add ChaCha using SIMD_4x32Jack Lloyd2018-11-0414-612/+279
| | | | | | | | | | | This allows supporting SSE2, NEON and AltiVec in a single codebase, so drop the NEON and SSE2 code. This new impl avoids having to do shuffles with every round and so is about 10% faster on Skylake. Also, fix bugs in both baseline and AVX2 implementations when the low counter overflowed. The SSE2 and NEON code were also buggy here.

| | | | | | | | | | | | | | | | | | | | which will cause incremental decoding to fail in ffi. related code(ffi_cipher.cpp): ```cpp BOTAN_ASSERT(cipher.update_granularity() > cipher.minimum_final_size(), "logic error"); ```

* Minor optimization when primality checkingJack Lloyd2018-10-311-2/+4
| | | | | | | Avoid doing the comparison against the largest hard coded prime, when we know the prime table is 16 bits and we already have to compute the bitsize of n in order to calculate the required number of Miller-Rabin iterations.
* Handle setting AD after a nonce correctly in AEADsJack Lloyd2018-10-314-7/+40
| | | | | | | | | | | In some cases (EAX, GCM, ChaCha20Poly1305) the mode does not handle this. However previously it handled it incorrectly by producing incorrect output. Instead reject it with an exception. Add a test that, if the mode accepts an AD before the nonce, then it must process the message correctly. This is similar to the existing test that if the mode accepts an AD before the key is set it must do the right thing with it.

* In ChaCha AVX2/SSE2 code s/input/state/Jack Lloyd2018-10-262-80/+79
| | | | | It is confusing as while the stream cipher state is the input to the permutation, the stream cipher has an unrelated input (the text).
