Do a cursory conversion of a few tests to GTest. For now, this is the laziest conversion possible. The intent is to just get the build setup ready so that we can get everything working in our consumers. The intended end state is: - The standalone build produces three test targets, one per library: {crypto,ssl,decrepit}_tests. - Each FOO_test is made up of: FOO/**/*_test.cc crypto/test/gtest_main.cc test_support - generate_build_files.py emits variables crypto_test_sources and ssl_test_sources. These variables are populated with FindCFiles, looking for *_test.cc. - The consuming file assembles those variables into the two test targets (plus decrepit) from there. This avoids having generate_build_files.py emit actual build rules. - Our standalone builders, Chromium, and Android just run the top-level test targets using whatever GTest-based reporting story they have. In transition, we start by converting one of two tests in each library to populate the three test targets. Those are added to all_tests.json and all_tests.go hacked to handle them transparently. This keeps our standalone builder working. generate_build_files.py, to start with, populates the new source lists manually and subtracts them out of the old machinery. We emit both for the time being. When this change rolls in, we'll write all the build glue needed to build the GTest-based tests and add it to consumers' continuous builders. Next, we'll subsume a file-based test and get the consumers working with that. (I.e. make sure the GTest targets can depend on a data file.) Once that's all done, we'll be sure all this will work. At that point, we start subsuming the remaining tests into the GTest targets and, asynchronously, rewriting tests to use GTest properly rather than cursory conversion here. When all non-GTest tests are gone, the old generate_build_files.py hooks will be removed, consumers updated to not depend on them, and standalone builders converted to not rely on all_tests.go, which can then be removed. (Unless bits end up being needed as a malloc test driver. I'm thinking we'll want to do something with --gtest_filter.) As part of this CL, I've bumped the CMake requirements (for target_include_directories) and added a few suppressions for warnings that GTest doesn't pass.

Prefer MSVC over GCC if both are in %PATH%. Notably, putting Strawberry Perl in %PATH% will usually end up putting a copy of gcc in %PATH%, which trips up people trying to build on Windows. This is arguably misusing the variable (normally set by the generator), but it should work.

Add support for building with the Android NDK. Previously I've been using the Linaro toolchains and just building static binaries. However, the Linaro toolchains have a broken pthread_rwlock_wrlock—it does nothing and then unlocking corrupts the lock. Building with the Android NDK avoids this. These build instructions depend on https://github.com/taka-no-me/android-cmake which people will need to clone into util/ if they want to use the Android NDK.

# Android-NDK CMake files reconfigure the path and so Go and Perl won't be
# found. However, ninja will still find them in $PATH if we just name them.
Fix discovery rule for perl and go for Android We don't use find_package/find_program on android to find go/perl because the android toolchain reconfigure the $PATH. The pervious way of solving this was to let ninja look for go/perl on the $PATH but this approach prevented us from specifying explicit go/perl executables what is needed for hermetic build using prebuilts. This CL changes the Android specific discovery rule to only set GO_EXECUTABLE and PERL_EXECUTABLE if they are not specified on the command line or inside the toolchain file.

Generate error data at build time. This avoids cluttering up the diff and making merge conflicts a pain. It does, however, mean we need to generate err_data.c ahead of time in Chromium and likely other downstream builds. It also adds a build dependency on Go.

Add a helper function for parsing extensions blocks. TLS 1.3 adds a number of places with extensions blocks that don't easily fit into our ClientHello/EncryptedExtensions callbacks. Between HelloRetryRequest, ServerHello, draft 18 going nuts with Certificate, and NewSessionTicket when we do 0-RTT, this passes the "abstract things that are repeated three times" sniff test. For now, it rejects unknown extensions, but it will probably grow an allow_unknown parameter for NewSessionTicket.

As part of this CL, I've bumped the CMake requirements (for target_include_directories) and added a few suppressions for warnings that GTest doesn't pass.

Fix build when using Visual Studio 2015 Update 1. Many of the compatibility issues are described at https://msdn.microsoft.com/en-us/library/mt612856.aspx. The macros that suppressed warnings on a per-function basis no longer work in Update 1, so replace them with #pragmas. Update 1 warns when |size_t| arguments to |printf| are casted, so stop doing that casting. Unfortunately, this requires an ugly hack to continue working in MSVC 2013 as MSVC 2013 doesn't support "%zu". Finally, Update 1 has new warnings, some of which need to be suppressed. --- Updated by davidben to give up on suppressing warnings in crypto/x509 and crypto/x509v3 as those directories aren't changed much from upstream. In each of these cases, upstream opted just blindly initialize the variable, so do the same. Also switch C4265 to level 4, per Microsoft's recommendation and work around a bug in limits.h that happens to get fixed by Google include order style. (limits.h is sensitive to whether corecrt.h, pulled in by stddef.h and some other headers, is included before it. The reason it affected just one file is we often put the file's header first, which means base.h is pulling in stddef.h. Relying on this is ugly, but it's no worse than what everything else is doing and this doesn't seem worth making something as tame as limits.h so messy to use.)

Add visibility rules. This change marks public symbols as dynamically exported. This means that it becomes viable to build a shared library of libcrypto and libssl with -fvisibility=hidden. On Windows, one not only needs to mark functions for export in a component, but also for import when using them from a different component. Because of this we have to build with |BORINGSSL_IMPLEMENTATION| defined when building the code. Other components, when including our headers, won't have that defined and then the |OPENSSL_EXPORT| tag becomes an import tag instead. See the #defines in base.h In the asm code, symbols are now hidden by default and those that need to be exported are wrapped by a C function. In order to support Chromium, a couple of libssl functions were moved to ssl.h from ssl_locl.h: ssl_get_new_session and ssl_update_cache.

aarch64 support. This is an initial cut at aarch64 support. I have only qemu to test it however—hopefully hardware will be coming soon. This also affects 32-bit ARM in that aarch64 chips can run 32-bit code and we would like to be able to take advantage of the crypto operations even in 32-bit mode. AES and GHASH should Just Work in this case: the -armx.pl files can be built for either 32- or 64-bit mode based on the flavour argument given to the Perl script. SHA-1 and SHA-256 don't work like this however because they've never support for multiple implementations, thus BoringSSL built for 32-bit won't use the SHA instructions on an aarch64 chip. No dedicated ChaCha20 or Poly1305 support yet.

Make build work on OS X with older cmake versions. `uname -p` is still i386 on OS X for some reason, which causes cmake 2.8 to set CMAKE_SYSTEM_PROCESSOR to i386, making the build think it's doing a 32-bit build. However, since the system is almost completely 64-bit these days, clang defaults to producing 64-bit object files unless told otherwise. As a result, the produced .o files are all 64-bit except for the .o files from assembly, and then linking fails. Fix this by forcing ARCH to 64-bit on OS X.

Do a cursory conversion of a few tests to GTest. For now, this is the laziest conversion possible. The intent is to just get the build setup ready so that we can get everything working in our consumers. The intended end state is: - The standalone build produces three test targets, one per library: {crypto,ssl,decrepit}_tests. - Each FOO_test is made up of: FOO/**/*_test.cc crypto/test/gtest_main.cc test_support - generate_build_files.py emits variables crypto_test_sources and ssl_test_sources. These variables are populated with FindCFiles, looking for *_test.cc. - The consuming file assembles those variables into the two test targets (plus decrepit) from there. This avoids having generate_build_files.py emit actual build rules. - Our standalone builders, Chromium, and Android just run the top-level test targets using whatever GTest-based reporting story they have. In transition, we start by converting one of two tests in each library to populate the three test targets. Those are added to all_tests.json and all_tests.go hacked to handle them transparently. This keeps our standalone builder working. generate_build_files.py, to start with, populates the new source lists manually and subtracts them out of the old machinery. We emit both for the time being. When this change rolls in, we'll write all the build glue needed to build the GTest-based tests and add it to consumers' continuous builders. Next, we'll subsume a file-based test and get the consumers working with that. (I.e. make sure the GTest targets can depend on a data file.) Once that's all done, we'll be sure all this will work. At that point, we start subsuming the remaining tests into the GTest targets and, asynchronously, rewriting tests to use GTest properly rather than cursory conversion here. When all non-GTest tests are gone, the old generate_build_files.py hooks will be removed, consumers updated to not depend on them, and standalone builders converted to not rely on all_tests.go, which can then be removed. (Unless bits end up being needed as a malloc test driver. I'm thinking we'll want to do something with --gtest_filter.) As part of this CL, I've bumped the CMake requirements (for target_include_directories) and added a few suppressions for warnings that GTest doesn't pass.
