In particular, eliminate the use of `ArrayEncoding::as_byte_array` as
we work towards removing that function because it uses `unsafe`.
Where `Block` is used in parameters to C/assembly code, I verified that
the C/assembly code uses `uint8_t *` as the function type (meaning
`uint8_t[16]`) in the BoringSSL headers. Until recently the stuff in
GCM was using `uint64_t` or a union containing `uint64_t`, which is why
block was previously defined in terms of `BigEndian<u64>`.
This is a step towards eliminating `unsafe` usage in `ring::endian` by
eliminating one use of `ArrayEncoding::as_byte_array`.
Since this is the only usage of `LittleEndian`, it is removed
completely.
This simple `array_flatten` polyfill will be useful for multiple
improvements towards eliminating the unsafe code in `endian`.
*ring* defined a function named `OPENSSL_memcmp` that did what
`CRYPTO_memcmp` does in BoringSSL, and BoringSSL has a different
function called `OPENSSL_memcmp`. *ring* doesn't need
`OPENSSL_memcmp` so sync the `CRYPTO_memcmp` stuff with BoringSSL.
This eliminates unnecessary differences from BoringSSL.
Our policy is to set warnings-as-errors only when buildingt from Git,
not when building from a packaged release. This flag is another aspect
of warnings-as-errors.
`dev_urandom_fallback` presently does nothing, so don't bother adding
it as a matrix dimension.
Because `dev_urandom_fallback` does nothing,
`--no-default-features --features=alloc` is effectively the same as the
default feature set, so don't add it as a matrix dimension.
`--all-features` is no longer appropriate after the ARM hardware feature
disabling features were added, so replace it with what we really want,
`--features=std,slow_tests`.
In the coverage section, `--features=alloc,dev_urandom_fallback,std` is
the same as `--features=std` since `alloc and `urandom_fallback` are
default features.
Move the Criterion.rs dependency out of *ring* into a new `ring-benches`
crate. This speeds up many build scenerios by eliminating a bunch of
dependencies from *ring*'s dependency tree for `cargo test`.
Implement `AsRef<[u8]>` for `signature::UnparsedPublicKey`, making it
possible to access the bytes of the public key. For consistency, I did
the same for `agreement::UnparsedPublicKey`, although it already has a
`bytes` method. `agreement::PublicKey` already uses the `AsRef<[u8]>`
approach.
Also, add missing `Debug` implementation for
`signature::UnparsedPublicKey`.
I agree to license my contributions to each file under the terms given
at the top of each file I changed.
Frequently lately one coverage job has been failing per job. Instead of
re-running the whole matrix again, make it so we just need to run the
(usually) one job that failed.
