2020-10-01version 0.3.70.3.7Jack O'Connor
Changes since 0.3.6: - BUGFIX: The C implementation was incorrect on big endian systems for inputs longer than 1024 bytes. This bug affected all previous versions of the C implementation. Little endian platforms like x86 were unaffected. The Rust implementation was also unaffected. @jakub-zwolakowski and @pascal-cuoq from TrustInSoft reported this bug: https://github.com/BLAKE3-team/BLAKE3/pull/118 - BUGFIX: The C build on x86-64 was producing binaries with an executable stack. @tristanheaven reported this bug: https://github.com/BLAKE3-team/BLAKE3/issues/109 - @mkrupcale added optimized implementations for SSE2. This improves performance on older x86 processors that don't support SSE4.1. - The C implementation now exposes the `blake3_hasher_init_derive_key_raw` function, to make it easier to implement language bindings. Added by @k0001.
2020-09-29add cross_test.sh for the C bindingsJack O'Connor
This will let us add big endian testing to CI for our C code. (We were already doing it for our Rust code.) This is adapted from test_vectors/cross_test.sh. It works around the limitation that the `cross` tool can't reach parent directories. It's an unfortunate hack, but at least it's only for testing. It might've been less hacky to use symlinks for this somehow, but I worry that would break things on Windows, and I don't want to have to add workarounds for my workarounds.

2020-08-31add i586-unknown-linux-musl as a test targetJack O'Connor
Samuel noticed that rustc seems to assume (incorrectly?) that all i686 targets support SSE2, but it doesn't make that assumption for i586.
2020-08-31add the dynamic check for SSE2 supportJack O'Connor
It will be very rare that this actually executes, but we should include it for completeness.
2020-08-31fix a build break on x86 targets without guaranteed SSE2 supportJack O'Connor
This is quite hard to trigger, because SSE2 has been guaranteed for a long time. But you could trigger it this way: rustup target add i686-unknown-linux-musl RUSTFLAGS="-C target-cpu=i386" cargo build --target i686-unknown-linux-musl Note a relevant gotcha though: The `cross` tool will not forward environment variables like RUSTFLAGS to the container by default, so if you're testing with `cross` you'll need to use the `rustc` command to explicitly pass the flag, as I've done here in ci.yml. (Or you could create a `Cross.toml` file, but I don't want to commit one of those if I can avoid it.)

Add SSE2 implementations
2020-08-31C: asm: simplify pblendw emulationMatthew Krupcale
Use statically calculated ~mask. This reduces the number of moves and registers necessary at the expense of an extra memory load. This is probably a good trade-off since we are not bound by memory uops in this loop.
2020-08-31Implement `fmt::Debug` using buildersNikolai Vazquez
This enables pretty printing via `{:#?}`. The normal style for `{:?}` is kept exactly the same.
2020-08-31C: asm: simplify pinsrd emulationMatthew Krupcale
Use punpckl{,q}dq instead of pinsrw.
2020-08-30C: asm: remove blendvps usage altogetherMatthew Krupcale
This simplifies the operation by removing the need to use blendvps at all.
2020-08-30C: Add blake3_hasher_init_derive_key_lenRenzo Carbonara
blake3_hasher_init_derive_key_len is an alternative version of blake3_hasher_init_derive_key which takes the context and its length as separate parameters, and not together as a C string. The motivation for this addition is making it easier for bindings to this C library to call this function without having to first copy over the context bytes just to add one 0x00 byte at the end. Notice that contrary to blake3_hasher_init_derive_key, blake3_hasher_init_derive_key_len allows the inclusion of a 0x00 byte in the context. Given the rules about context string selection, this byte is unlikely to be used as part of a context string. But if for some reason it is ever given, it will be included in the context string and processed like any other non-alphanumeric byte would. For compatibility with blake3_hasher_init_derive_key, bindings should still check for the absence of 0x00 bytes.

2020-08-25Write _mm_blend_epi16 emulation without multiplicationMatthew Krupcale
Use _mm_and_si128 and _mm_cmpeq_epi16 rather than expensive multiplication _mm_mullo_epi16 with _mm_srai_epi16 that compiler may not be able to optimize.
2020-08-24Fix Windows MSVC undefined symbol errorsMatthew Krupcale
MSVC returns "error A2006:undefined symbol : FFFFFFFFH", so use 0FFFFFFFFH instead. Also use 0 prefix for 0H to align things.
2020-08-24Put PBLENDW masks in the RDATA sectionMatthew Krupcale
Previously, these masks were undefined because they were outside of the RDATA section.
2020-08-24Fix Windows MSVC undefined symbol errorsMatthew Krupcale
MSVC returns "error A2006:undefined symbol : B1H", so use 0B1H instead.

2020-08-23Fix #109Samuel Neves
The default executable stack setting on Linux can be fixed in two different ways: - By adding the `.section .note.GNU-stack,"",%progbits` special incantation - By passing the `--noexecstack` flag to the assembler This patch implements both, but only one of them is strictly necessary. I've also added some additional hardening flags to the Makefile. May not be portable.
