* Need to ensure minimum size hereJack Lloyd2018-11-271-0/+1
| | | | Previously handled by the early exit
* Optimizations for NIST reductionJack Lloyd2018-11-261-22/+20
| | | | Also avoid an early exit in P-521
* Make more BigInt functions const-timeJack Lloyd2018-11-267-135/+328
| | | | In particular comparisons, calc sig words, and mod_sub are const time now.
* Deprecate SRP suites [ci skip]Jack Lloyd2018-11-261-0/+4
| | | | | This is kind of implicit by the deprecation of CBC ciphersuites but should be called out more clearly.

| * Make exceptions easier to translate to error codesJack Lloyd2018-11-2381-359/+655
| | | | | | | | | | | | | | | | | | | | | | Avoid throwing base Botan::Exception type, as it is difficult to determine what the error is in that case. Add Exception::error_code and Exception::error_type which allows (for error code) more information about the error and (for error type) allows knowing the error type without requiring a sequence of catches. See GH #1742
* | Implement const time select based on xor-swapJack Lloyd2018-11-231-1/+2
| | | | | | | | | | For some compilers this may make the difference between compiling using bitmasks as intendeded, and compiling with a conditional jump.

| * Add typecast_copyJack Lloyd2018-11-173-30/+48
| | | | | | | | | | Wraps memcpy in the cases where we really are doing a type conversion using memcpy
| * Avoid calling memset, memcpy within library codeJack Lloyd2018-11-1717-27/+36
| | | | | | | | | | | | | | | | | | Prefer using wrappers in mem_utils for this. Current exception is where memcpy is being used to convert between two different types, since copy_mem requires input and output pointers have the same type. There should be a new function to handle conversion-via-memcpy operation.

* 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.
* Fix Sonar warningJack Lloyd2018-11-171-1/+1

* 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 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.

| * 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.

|/ | | | | | | 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.

* 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.
