* Release 4.10.3 (#280)
* Create semgrep.yml
Creating Semgrep.yml file - Semgrep is a tool that will be used to scan Cloudflare's public repos for Supply chain, code and secrets. This work is part of Application & Product Security team's initiative to onboard Semgrep onto all of Cloudflare's public repos.
In case of any questions, please reach out to "Hrushikesh Deshpande" on cf internal chat.
* Add "fips-compat" feature (#286)
This adds a feature to build against a BoringSSL version compatible with
the current boringssl-fips, but _without_ actually enabling the `fips`
feature.
This can be useful to use with `fips-link-precompiled` while using a
custom BoringSSL version based on the older FIPS branch.
* boring-sys: include HPKE header file for bindgen
BoringSSL doesn't expose these APIs for FIPs builds, so we gate them
here as well
* Release 4.11.0
* Add `set_cert_verify_callback` (`SSL_CTX_set_cert_verify`)
Add a wrapper for `SSL_CTX_set_cert_verify`, which allows consumers to
override the default certificate verification behavior.
The binding resembles `SSL_CTX_set_verify`'s.
See
https://docs.openssl.org/master/man3/SSL_CTX_set_cert_verify_callback/
for more details.
* Skip bindgen 0.70's layout tests before Rust 1.77
* (ci): brew link x86 toolchain for macos13 runner
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
Fixes https://github.com/cloudflare/boring/issues/285
* feat(boring): Add SSL_CURVE_X25519_MLKEM768 curve binding

This adds a feature to build against a BoringSSL version compatible with
the current boringssl-fips, but _without_ actually enabling the `fips`
feature.
This can be useful to use with `fips-link-precompiled` while using a
custom BoringSSL version based on the older FIPS branch.
set_surves_list is similar to set_curves, but the curves are specified
by a string. This makes it convenient when the supported curves of
the underlying BoringSSL is not known at compile time.
Also fix a bug in checking return value of SSL_set1_curves_list.
Our rustdocs are miserably broken. We manually link to openssl docs in
most binding definitions, and openssl keeps changing their documentation
URL, so in order to fix everything I'd have to touch every single
binding definition in every single file. Instead, we should use the
`corresponds` macro from the openssl-macros crate which nicely adds a
link to the openssl documentation on our behalf. If the openssl
documentation url ever changes again in the future, a simple dependency
bump should solve the issue.
We previously added an `SslCurveId` struct to house SSL_CURVE variants of
the internal NID constants, to allow `SslRef::curve()` to properly
instantiate `SslCurve` structures. This was done to ensure
`SslRef::set_curves()` did not break, as it expects the internal NID
constants instead of the public SSL_CURVE ones. In future versions of
boringssl, this problem is solved by virtue of the
SSL_CTX_set1_group_ids API. Since we don't have this yet, this commit
adds `SslCurve::nid()` so `SslRef::set_curves()` can convert the
SSL_CURVE constants to the NID representation internally
without breaking the public API.
Some functions use the NID_* constants, and some use the SSL_CURVE_* ones.
Extract from the documentation:
> Where NIDs are unstable constants specific to OpenSSL and BoringSSL, group IDs are defined by the TLS protocol. Prefer the group ID representation if storing persistently, or exporting to another process or library.
Fix three potential timing sidechannels. These don't affect ephemeral
usage of Kyber as in TLS, but it's good practice to get rid of them anyway.
Also adds IPDWing, a preliminary version of X-Wing using the initial public
draft (IPD) of ML-KEM. Don't use it.
The client sent ciphers in the ClientHello are unparsed and thus require
the user to convert u16s into SslCipher instances. It could be worth
doing this parsing in the library itself to make things consistent and
always return a StackRef<SslCipher>.
This feature expects a recent boringssl checkout (such as the one
found in boring-sys/deps/boringssl), so it should not be using
the same bindings as the fips feature, which are based on
boring-sys/deps/boringssl-fips, which is older and with a different
API.
This helps drive async callbacks from outside tokio-boring, such as in quiche.
Not a breaking change because every public item in tokio-boring is preserved as is.
Setting callbacks multiple times on a SslContextBuilder causes the previous callback
installed to leak, using replace_ex_data internally prevents that.
We also start using it in tokio-boring in with_ex_data_future, my understanding
is that the futures currently in use are never installed twice by that function
but that could change in the future with the addition of more async callbacks.
We introduce new methods replace_ex_data for both SslContextBuilder
and Ssl in case anyone is relying on the leaking behaviour of their
set_ex_data methods, but we do document that they leak now.
