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.
This was an accidental regression in
d1ee9bfd86 which leads to pulling in the
full featureset of tokio and hyper for all dependents of tokio-boring
and hyper-boring.
Fixes#179.
Feature no-patches is ever only useful when setting other env variables
BORING_BSSL{,_FIPS}{,_SOURCE}_PATH, and it has no impact on the APIs
provided by any of the boring crates, so we may as well make it an env
variable itself so downstream users have less features to propagate
across their own crate graph.
Feature rpk in boring doesn't do anything unless you
explicitly use `SslAcceptor::rpk` or `SslContext::rpk_builder`,
and neither of these types are directly reachable if the
user depends only on tokio-boring or hyper-boring, which
means you still need to explicitly depend on the boring crate
to use RPK, in which case you can enable the feature there.
Builds using feature fips or fips-link-precompiled now
read variables prefixed by BORING_BSSL_FIPS_ instead of
BORING_BSSL_. This helps complex builds where build dependencies
also use boring, where we may not want to use fips there.
Without those separate variables, the boring build for the
build dependencies end up relying on e.g. BORING_BSSL_PATH,
causing errors if this path is a boring checkout intended for
fips builds, while the fips feature isn't enabled for
the build dependency.
These two new kinds of methods immediately return a MidHandshakeSslStream
instead of actually initiating a handshake. This greatly simplifies
loops around MidHandshakeSslStream::WouldBlock.
* 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.

- Major version for boring-sys: `PasswordCallback` was removed
- Major version for boring: the public `*Ref` types were removed and `foreign-types` appears in our public api and had a major version bump
- Patch version for tokio-boring: the only API change was removing the `S: Debug` bound
- Patch version for hyper-boring: no API changes, only removed dependencies
`tokio_boring::HandshakeError` currently requires that the inner stream
implements `Debug` for its `Display` implementation. This constraint is
unnecessary.
This change removes this `Debug` constraint so `HandshakeError` always
implements `Display`.
