* Add compile-time rotation functionsJack Lloyd2017-10-1211-370/+381
| | | | | | | | | | | | | | | | | The problem with asm rol/ror is the compiler can't schedule effectively. But we only need asm in the case when the rotation is variable, so distinguish the two cases. If a compile time constant, then static_assert that the rotation is in the correct range and do the straightforward expression knowing the compiler will probably do the right thing. Otherwise do a tricky expression that both GCC and Clang happen to have recognize. Avoid the reduction case; instead require that the rotation be in range (this reverts 2b37c13dcf). Remove the asm rotations (making this branch illnamed), because now both Clang and GCC will create a roll without any extra help. Remove the reduction/mask by the word size for the variable case. The compiler can't optimize that it out well, but it's easy to ensure it is valid in the callers, especially now that the variable input cases are easy to grep for.

* Add wrappers for reinterpret_cast between char* and uint8_t*Jack Lloyd2017-10-031-1/+1
| | | | | | | Generally speaking reinterpret_cast is sketchy stuff. But the special case of char*/uint8_t* is both common and safe. By isolating those, the remaining (likely sketchy) cases are easier to grep for.

* Modify GOST-34.11 hash to avoid a GCC miscompilation.Jack Lloyd2017-08-131-1/+4
| | | | | | | | | | | | For whatever reason GCC 7 on i386 miscompiles this loop under -O3. I was not able to reduce the bug to a small testcase - extracting the problem section of the code to its own file, it behaves correctly. Also oddly, I was never able to repro this using Arch's gcc-multilib i386 compiler. But when compiled with the 'native' i386 compiler in a chroot it immediately fails. See GH #1148 and GH #882

| | | | | | | | | | | | | | This commit implements the feedback from @securitykernel on the PR and also changes the EC Group comparison to use the OID, akin to OpenSSL. The EC Group comparison was needed before GH #1093 was merged, but now we can go use the OpenSSL variant.
| * BearSSL: Initial support and hash testsPatrick Wildt2017-07-051-1/+16
| | | | | | | | | | | | | | | | | | BearSSL is an implementation of the SSL/TLS protocol in C aiming to be correct and secure, small and highly portable. Thus making it nicer to be included in a rather sparse bootloader. This commit adds support for BearSSL's hash routines only, with more stuff coming up in following commits. The goal is to be able to test BearSSL using Botan's extensive testsuite.
* | Use native compiler versioning of MSVCSimon Warta2017-07-312-2/+2
|/ | | | | | | | | | | | | | | | While using marketing names like 2013, 2015 etc. is more convenient at first sight, it requires keeping a table about all supported compiler versions, as there is no formular to calculate between the representations. Keeping a list of compilers leads to the following issue: if one version of Botan is released in 2017, requiring MSVS 2015 for one module, this source can be compiled using MSVS 2015 and 2017 but not a future version like 2019. Also preview/development versions of MSVC that may use an intermediate version number cannot be handled with the marketing name table because they may be unknown to the general public.
* Cleanups in SM3 codeJack Lloyd2017-06-291-81/+25
