* Merge GH #665 Add IncludeOS target, make filesystem/threads optionalJack Lloyd2016-10-1720-1/+50
|\
| * Add ISA annotations to functions using SIMD, AES, etcJack Lloyd2016-10-141-1/+8
| | | | | | | | | | | | | | | | Also emit `#pragma GCC target` in the ISA specific amalgamation files. This allows compiling without any special compiler flags, at least with GCC 6.2 and Clang 3.8. The ISA annotations are ignored in MSVC, which just emits whatever instruction the intrinsic requires.

* Travis CI additions and cleanupJack Lloyd2016-08-282-3/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Convert Travis build configuration to a single var instead of 4 tuple. Makes it much easier to review the builds in the Travis web UI. Adds sanitizer builds for Clang on both Linux and OS X. Clang is a different compiler from GCC and its sanitizers may catch things GCC does not. I have no idea if Apple's Clang has some magic sanitizer sauce stock LLVM does not, so maybe sanitizer build on OS X can be skipped. Adds Linux cross compile targets for ARM32, ARM64, PPC64, and MinGW x86 using the cross compiler available in Trusty. All of them build and are set up to run through qemu/wine. All of the tests currently fail and so are marked as expected fail in the Travis matrix. The ARM test runs seem to have thread problems; ARM32 thread creation just fails with an exception, as if pthreads was disabled. All other tests pass ok for ARM32. On Aarch64, it looks like there is a hard crash the first time the library tries creating a thread. Both of these might be due to statically linking the binary? I have been unable to convince Ubuntu's qemu-ppc64 to execute binaries compiled by Ubuntu's ppc64 cross compiler. I'm downloading an Ubuntu ISO to try this in a VM. Running under Wine exposes several issues, both in Wine and Botan. Many functions are stubs and it appears that entropy collection fails as a result. This triggers a bug in the FFI tests which causes a crash there. A pox on time zones; _mkgmtime is a MSVC extension and is not available on MinGW GCC. Add a last resort call that just uses the localzone variant instead. Adds valgrind target, remove a bogus poison in pubkey.cpp (it was effectively asserting that all of RSA was const time which is sadly not true at all). Moves -Wshadow to maintainer mode for GCC - GCC 4.8 has a noisy variant of -Wshadow which warns if a parameter masks a function name, but this comes up all the time in constructors. Later GCCs no longer warn about this (even with -Wshadow), so the warnings are never fixed, but they cause noise in CI output and hide interesting warnings like warning: vec_lvsl is deprecated for little endian; use assignment for unaligned loads and stores [-Wdeprecated] __vector unsigned char perm = vec_lvsl(0, static_cast<u32bit*>(nullptr));
* RNG changes (GH #593)Jack Lloyd2016-08-243-7/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Change reseed interval logic to count calls to `randomize` rather than bytes, to match SP 800-90A Changes RNG reseeding API: there is no implicit reference to the global entropy sources within the RNGs anymore. The entropy sources must be supplied with the API call. Adds support for reseding directly from another RNG (such as a system or hardware RNG). Stateful_RNG keeps optional references to both an RNG and a set of entropy sources. During a reseed, both sources are used if set. These can be provided to HMAC_DRBG constructor. For HMAC_DRBG, SP800-90A requires we output no more than 2**16 bytes per DRBG request. We treat requests longer than that as if the caller had instead made several sequential maximum-length requests. This means it is possible for one or more reseeds to trigger even in the course of generating a single (long) output (generate a 256-bit key and use ChaCha or HKDF if this is a problem). Adds RNG::randomize_with_ts_input which takes timestamps and uses them as the additional_data DRBG field. Stateful_RNG overrides this to also include the process ID and the reseed counter. AutoSeeded_RNG's `randomize` uses this. Officially deprecates RNG::make_rng and the Serialized_RNG construtor which creates an AutoSeeded_RNG. With these removed, it would be possible to perform a build with no AutoSeeded_RNG/HMAC_DRBG at all (eg, for applications which only use the system RNG).

| * | Remove configure extra information from build.hSimon Warta2016-08-161-2/+2
| |/ | | | | | | | | | | | | | | | | | | | | | | Removes user and hostname: as mentioned by a downstream maintainer, the information should not be included in packages. In our projects, the information is contained in the amalgamation check-in commit message. Removes timestamp: this ensures that the header content is equal in two equal configure runs. Both changes together make it possible to effectively use compiler caches for Botan (ccache on Unix, in direct mode; clcache on Windows).
* / Check configured CPU arch against compiler settingSimon Warta2016-08-161-0/+16
|/ | | | | | | | | | | | | | This adds a fast fail when trying to build Botan configured for 32 bit using a 64 bit compiler or vice versa. Check running python configure.py --cpu="x86_32" && make python configure.py --cpu="x86_64" && make or python configure.py && nmake on 64 bit Windows in a 32 bit Command Prompt. Closes #456.

* Address some review comments from @cordneyJack Lloyd2016-07-171-1/+1
| | | | | | | | | Use consistent naming for the max output before reseed parameter. The constant (default) value is renamed to BOTAN_RNG_DEFAULT_MAX_OUTPUT_BEFORE_RESEED, since without the DEFAULT_ it reads like a compile time maximum instead. Use uint8_t instead of byte.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A module policy is a file specifying three types of modules: ones which are required, ones which are prohibited, and ones which should be used if otherwise available (this is mostly for platform specific modules). Finally there are whatever modules which exist in the library of which the policy makes no mention. These will be included if an explicit dependency of some other module pulls them in (so there is no reason to mention base, utils, ... in the file) but skipped otherwise. For example policy 'sane' does not mention 'utils' or 'twofish' either way. Since utils is a dependency of other modules which are included, but Twofish does not. However unlike an explicitly prohibited module, not mentioned can still be requested as part of the build (here with --enable-module=twofish) Also fixes some test bugs noticed by compiling in different build configs. DLIES test didn't check that the KDF and MAC existed. Adds a typedef for MessageAuthenticationCode because typing it twice in a single line in the DLIES test made me think it's way too long. :) Also fix some fuzzer build problems. Due to a copy and paste bug the PKCS certificate (it was not). Inspired by GH #439
