2018-01-18curve25519-fiat32: uninline certain functionsJason A. Donenfeld
While this has a negative performance impact on x86_64, it has a positive performance impact on smaller machines, which is where we're actually using this code. For example, an A53: Before: fiat32: 228605 cycles per call After: fiat32: 188307 cycles per call Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2017-12-09global: add SPDX tags to all filesGreg Kroah-Hartman
It's good to have SPDX identifiers in all files as the Linux kernel developers are working to add these identifiers to all files. Update all files with the correct SPDX license identifier based on the license text of the project or based on the license in the file itself. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Modified-by: Jason A.

2017-12-03chacha20-arm: fix with clang -fno-integrated-as.David Benjamin
The __clang__-guarded #defines cause gas to complain if clang is passed -fno-integrated-as. Emitting .syntax unified when those are used fixes this. Reviewed-by: Andy Polyakov <appro@openssl.org> Reviewed-by: Kurt Roeckx <kurt@roeckx.be> Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2017-11-26blake2s: tweak avx512 codeSamuel Neves
This is not as ideal as using zmm, but zmm downclocks. And it's not as fast single-threaded as using the gathers. But it is faster when multithreaded, which is what WireGuard is doing. Signed-off-by: Samuel Neves <sneves@dei.uc.pt> Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2017-11-22poly1305-x86_64: unclobber %rbpSamuel Neves
OpenSSL's Poly1305 kernels use %rbp as a scratch register. However, the kernel expects rbp to be a valid frame pointer at any given time in order to do proper unwinding. Thus we need to alter the code in order to preserve it. The most straightforward manner in which this was accomplished was by replacing $d3 in poly1305-x86_64.pl -- formerly %r10 -- by %rdi, and replace %rbp by %r10. Because %rdi, a pointer to the context structure, does not change and is not used by poly1305_iteration, it is safe to use it here, and the overhead of saving and restoring it should be minimal.
