* RTG-3333 Support X25519MLKEM768 by default, but don't sent it as client
X25519MLKEM768 is the standardised successor of the preliminary
X25519Kyber768Draft00. Latest browsers have switched to X25519MLKEM768.
Cloudflare supports both on the edge.
We've had support for X25519MLKEM768 in this crate for a while, but
didn't enable by default. We're now enabling serverside support by
default. We also let clients advertise support when set
to kx-client-pq-supported.
We don't enable support by default yet for clients set to
kx-client-pq-preferred, as that would cause an extra round-trip due to
HelloRetryRequest if the server doesn't support X25519MLKEM768 yet.
BoringSSL against which we build must support X25519MLKEM768, otherwise
this will fail.
* replace once_cell with LazyLock
We can drop the once_cell dependency since the same functionality is
implemented in std now.
Requires bumping MSRV to 1.80.
* fix manual_c_str_literals clippy warning
* chore: Fix docs on SslRef::replace_ex_data
* Detailed error codes
* Clean up boring_sys::init()
We don't need the workaround that was initially introduced for a bug in
openssl, and OPENSSL_init_ssl always calls into CRYPTO_library_init on
boringssl, so just call it explicitly.
* Expose EVP_HPKE_KEY
* Expose client/server-side ECH
Resolves https://github.com/cloudflare/boring/issues/282
* Clean up ECH tests
* Expose SSL_set_enable_ech_grease
* Use corresponds macro
* build: Fix the build for 32-bit Linux platform (#312)
build: Fix the build for 32-bit Linux platform
* Set CMAKE_BUILD_PARALLEL_LEVEL to available_parallelism
cmake-rs' jobserver doesn't work reliably, if at all. One workaround is
to set CMAKE_BUILD_PARALLEL_LEVEL to available_parallelism(). On my
machine it shaves ~35 seconds off of boring-sys builds.
* Expose SSL_CTX_set1_ech_keys from SslContextRef
We currently expose this method on `SslContextBuilder`, which is fine
for bootstrapping an `SSL_CTX`, but subsequent attempts to set ECH keys
(like during key rotation) can only happen via `SslContextRef`. Also
update the method on the builder to take an immutable reference to self
because the API is thread safe.
* Bump cmake-rs to improve Mac OS build parallelism
There's a bug on OSX that prevents the CMake jobserver from working
properly, and so CMake defaults to a single-threaded build. It's not
clear when this is actually going to get fixed, so recent versions of
cmake-rs just disable the jobserver and have CMake fall back to the
number of available cores:
https://github.com/rust-lang/cmake-rs/pull/229
This means we don't need e6833b0074
* Release 4.14.0 (#317)
* Actually expose SslEchKeys
* Address clippy lints
* Revert "Refactor!: Introduce a Cargo feature for optional Hyper 0 support"
This reverts commit 49d5a61163.
* Revert "Refactor!: Remove strict `TokioIo` response requirement from `hyper_boring::v1::HttpsConnector`"
This reverts commit e518c2444a.
* Introduce a builder pattern for SslEchKeys + make set_ech_keys take a reference (#320)
Previously, set_ech_keys would consume the SslEchKeys struct to enforce
the requirement that the struct is immutable after initializing it on a
SSL_CTX. The problem with this is that it requires applications to
needlessly reallocate the SslEchKeys struct if they want to initialize
keys on multiple SSL_CTXs, which is a pretty common pattern. To work
around this, we introduce a builder (SslEchKeysBuilder) that requires
mutable access to add keys to the underlying struct. set_ech_keys takes
in a reference to SslEchKeys, which can only be made via consuming the
builder.
* Revert cmake bump (for now) as it is overly restrictive (#321)
Some users of boring have issues with newer versions of cmake. Because
we have an alternative solution, we can hold off on the bump for now.

Closes#294. Requires breaking changes. The default v0 is changed in
favor of v1, but v0 is still kept available, just in a forced module
path. It enables dependency de-duplication when consuming it.

It seems we need to manually symlink the x86_64-unknown-linux-gnu
toolchain for the macos13 runner. Also, we don't need to overwrite the
python version anymore

Overwrite boringSSL's default key exchange preferences with safe
defaults using feature flags:
* "kx-pq-supported" enables support for PQ key exchange algorithms.
Classical key exchange is still preferred, but will be upgraded to PQ
if requested.
* "kx-pq-preferred" enables preference for PQ key exchange,
with fallback to classical key exchange if requested.
* "kx-nist-required" disables non-NIST key exchange.
Each feature implies "kx-safe-default". When this feature is enabled,
don't compile bindings for `SSL_CTX_set1_curves()` and `SslCurve`. This
is to prevent the feature flags from silently overriding curve
preferences chosen by the user.
Ideally we'd allow both: that is, use "kx-*" to set defaults, but still
allow the user to manually override them. However, this doesn't work
because by the time the `SSL_CTX` is constructed, we don't yet know
whether we're the client or server. (The "kx-*" features set different
preferences for each.) If "kx-sfe-default" is set, then the curve
preferences are set just before initiating a TLS handshake
(`SslStreamBuilder::connect()`) or waiting for a TLS handshake
(`SslStreamBuilder::accept()`).
While it's possible to build Rust tests into an iOS app, start up
a simulator instance, upload the tests there, and launch them --
that's a bit involved process. For now, just check that BoringSSL
compiles for the specified target. Use "--all-targets" to check
all targets, including the unit tests.
Even if "cargo test --target ${arch}-apple-ios" cross-compiles tests,
it's not possible to actually run them on the host macOS, as that's
a different execution environment.
Although, I guess, we could try only building tests with "--no-run",
GitHub Actions do not make it easy to construct command lines based
on matrix parameters. Thus it's easier to disable these steps, and
the following commit adds a "--no-run" step with "--target".
* Add rerun-if-env-changed instructions for BORING_* variables
* Use X509_get0_notBefore() and X509_get0_notAfter() instead of X509_getm_notBefore() and X509_getm_notAfter().
According to
https://www.openssl.org/docs/man1.1.0/man3/X509_getm_notBefore.html,
"X509_getm_notBefore() and X509_getm_notAfter() are similar to
X509_get0_notBefore() and X509_get0_notAfter() except they return
non-constant mutable references to the associated date field of the
certificate".
* Only update boringssl submodule if BORING_BSSL_PATH not provided
* Allow BORING_BSSL_LIB_PATH to control link search
* Add fips feature
* Use X509_set_notAfter unconditionally for FIPS compatibility
This is equivalent according to
https://boringssl.googlesource.com/boringssl/+/c947efabcbc38dcf93e8ad0e6a76206cf0ec8072
The version of boringssl that's FIPS-certified doesn't have `X509_set1_notAfter`.
The only difference between that and `X509_set_notAfter` is whether they're const-correct,
which doesn't seem worth having two different code-paths.
* Check out fips commit automatically
* Verify the version of the compiler used for building boringssl
NIST specifies that it needs to be 7.0.1; I originally tried building with clang 10 and it failed.
Theoretically this should check the versions of Go and Ninja too, but they haven't given me trouble in practice.

This ensures that all the Rust functions, types and constants
always match the actual BoringSSL definitions.
It also removes quite a lot of manually maintained code, as well
as the need for systest.
The value for `SslOptions::ALL`, for example, was wrong. On current
BoringSSL versions, this is a no-op, and is set to `0`.
Clearing it does nothing. So, the `clear_ctx_options` test, that
passed by accident, was adjusted to use a different option.
The `libc` crate is not required, as we only use it for types that
are already defined in the standard library. It was removed from
`boring-sys`. The same can be done to other crates later.
