After much procrastinating, we finally moved Chromium to the new stuff.
We can now delete this. This is a breaking change for
SSL_PRIVATE_KEY_METHOD consumers, but it should be trivial (remove some
unused fields in the struct). I've bumped BORINGSSL_API_VERSION to ease
any multi-sided changes that may be needed.

We enforce that servers don't send bogus ALPN values, so consumers may
assume that SSL_get0_alpn_selected won't have anything terribly weird.
To maintain that invariant in the face of folks whose ALPN preferences
change (consider a persisted session cache), we should decline to offer
0-RTT if early_alpn would have been rejected by the check anyway.

Although we are derived from 1.0.2, we mimic 1.1.0 in some ways around
our FOO_up_ref functions and opaque libssl types. This causes some
difficulties when porting third-party code as any OPENSSL_VERSION_NUMBER
checks for 1.1.0 APIs we have will be wrong.
Moreover, adding accessors without changing OPENSSL_VERSION_NUMBER can
break external projects. It is common to implement a compatibility
version of an accessor under #ifdef as a static function. This then
conflicts with our headers if we, unlike OpenSSL 1.0.2, have this
function.
This change switches OPENSSL_VERSION_NUMBER to 1.1.0 and atomically adds
enough accessors for software with 1.1.0 support already. The hope is
this will unblock hiding SSL_CTX and SSL_SESSION, which will be
especially useful with C++-ficiation. The cost is we will hit some
growing pains as more 1.1.0 consumers enter the ecosystem and we
converge on the right set of APIs to import from upstream.
It does not remove any 1.0.2 APIs, so we will not require that all
projects support 1.1.0. The exception is APIs which changed in 1.1.0 but
did not change the function signature. Those are breaking changes.
Specifically:
- SSL_CTX_sess_set_get_cb is now const-correct.
- X509_get0_signature is now const-correct.
For C++ consumers only, this change temporarily includes an overload
hack for SSL_CTX_sess_set_get_cb that keeps the old callback working.
This is a workaround for Node not yet supporting OpenSSL 1.1.0.
The version number is set at (the as yet unreleased) 1.1.0g to denote
that this change includes https://github.com/openssl/openssl/pull/4384.

We currently forbid the server certificate from changing on
renegotiation. This means re-verifying the certificate is pointless and
indeed the callback being called again seems to surprise consumers more
than anything else.
Carry over the initial handshake's SCT lists and OCSP responses (don't
enforce they don't change since the server may have, say, picked up new
OCSP responses in the meantime), ignore new ones received on
renegotiation, and don't bother redoing verification.
For our purposes, TLS 1.2 renegotiation is an overcomplicated TLS 1.3
KeyUpdate + post-handshake auth. The server is not allowed to change
identity.

The previous attempt around the 'struct ssl_st' compatibility mess
offended OSS-Fuzz and UBSan because one compilation unit passed a
function pointer with ssl_st* and another called it with
bssl::SSLConnection*.
Linkers don't retain such types, of course, but to silence this alert,
instead make C-visible types be separate from the implementation and
subclass the public type. This does mean we risk polluting the symbol
namespace, but hopefully the compiler is smart enough to inline the
visible struct's constructor and destructor.

This is horrible, but everything else I tried was worse. The goal with
this CL is to take the extern "C" out of ssl/internal.h and move most
symbols to namespace bssl, so we can start using C++ helpers and
destructors without worry.
Complications:
- Public API functions must be extern "C" and match their declaration in
ssl.h, which is unnamespaced. C++ really does not want you to
interleave namespaced and unnamespaced things. One can actually write
a namespaced extern "C" function, but this means, from C++'s
perspective, the function is namespaced. Trying to namespace the
public header would worked but ended up too deep a rabbithole.
- Our STACK_OF macros do not work right in namespaces.
- The typedefs for our exposed but opaque types are visible in the
header files and copied into consuming projects as forward
declarations. We ultimately want to give SSL a destructor, but
clobbering an unnamespaced ssl_st::~ssl_st seems bad manners.
- MSVC complains about ambiguous names if one typedefs SSL to bssl::SSL.
This CL opts for:
- ssl/*.cc must begin with #define BORINGSSL_INTERNAL_CXX_TYPES. This
informs the public headers to create forward declarations which are
compatible with our namespaces.
- For now, C++-defined type FOO ends up at bssl::FOO with a typedef
outside. Later I imagine we'll rename many of them.
- Internal functions get namespace bssl, so we stop worrying about
stomping the tls1_prf symbol. Exported C functions are stuck as they
are. Rather than try anything weird, bite the bullet and reorder files
which have a mix of public and private functions. I expect that over
time, the public functions will become fairly small as we move logic
to more idiomatic C++.
Files without any public C functions can just be written normally.
- To avoid MSVC troubles, some bssl types are renamed to CPlusPlusStyle
in advance of them being made idiomatic C++.

TLS 1.3 deployment is currently blocked by buggy middleboxes
throughout the ecosystem. As an experiment to better understand these bugs
and the problems they are causing, implement TLS 1.3 variants with
alternate encodings. These are still the same protocol, only encoded
slightly differently. We will use what we learn from these experiments to
guide the TLS 1.3 deployment strategy and proposals to the IETF, if any.
These experiments only target the basic 1-RTT TLS 1.3 handshake. Based on
what we learn from this experiment, we may try future variations to
explore 0-RTT and HelloRetryRequest.
When enabled, the server supports all TLS 1.3 variants while the client

Rather than adding a new mode to EVP_PKEY_CTX, upstream chose to tie
single-shot signing to EVP_MD_CTX, adding functions which combine
EVP_Digest*Update and EVP_Digest*Final. This adds a weird vestigial
EVP_MD_CTX and makes the signing digest parameter non-uniform, slightly
complicating things. But it means APIs like X509_sign_ctx can work
without modification.
Align with upstream's APIs. This required a bit of fiddling around
evp_test.cc. For consistency and to avoid baking details of parameter
input order, I made it eagerly read all inputs before calling
SetupContext. Otherwise which attributes are present depend a lot on the
shape of the API we use---notably the NO_DEFAULT_DIGEST tests for RSA
switch to failing before consuming an input, which is odd.
(This only matters because we have some tests which expect the operation
to abort the operation early with parameter errors and match against
Error. Those probably should not use FileTest to begin with, but I'll
tease that apart a later time.)
Upstream also named NID_Ed25519 as NID_ED25519, even though the
algorithm is normally stylized as "Ed25519". Switch it to match.

As a precursor to removing the code entirely later, disable the protocol
by default. Callers must use SSL_CTX_set_min_version to enable it.
This change also makes SSLv3_method *not* enable SSL 3.0. Normally
version-specific methods set the minimum and maximum version to their
version. SSLv3_method leaves the minimum at the default, so we will
treat it as all versions disabled. To help debugging, the error code is
switched from WRONG_SSL_VERSION to a new NO_SUPPORTED_VERSIONS_ENABLED.
This also defines OPENSSL_NO_SSL3 and OPENSSL_NO_SSL3_METHOD to kick in

hook for any upstreaming changes that may be needed. (OPENSSL_NO_SSL3

This adds support on the server and client to accept data-less early
data. The server will still fail to parse early data with any
contents, so this should remain disabled.

The |select_certificate_cb| return values are somewhat confusing due
to the fact that they don't match the |cert_cb| ones, despite the
similarities between the two callbacks (they both have "certificate" in
the name! well, sort of).
This also documents the error return value (-1) which was previously
undocumented, and it expands the |SSL_CTX_set_select_certificate_cb|
documentation regarding retrial (by shamelessly copying from
|SSL_CTX_set_ticket_aead_method|).
Also updates other scattered documentation that was missed by previous
changes.

We'll measure this value to guide what tolerance to use in the 0-RTT
anti-replay mechanism. This also fixes a bug where we were previously
minting ticket_age_add-less tickets on the server. Add a check to reject
all those tickets.

Due to middlebox and ecosystem intolerance, short record headers are going to
be unsustainable to deploy.

The DTLS stack has two very different APIs for handling timeouts. In
non-blocking mode, timeouts are driven externally by the caller with
DTLSv1_get_timeout. In blocking mode, timeouts are driven by the BIO by
calling a BIO_ctrl with BIO_CTRL_DGRAM_SET_NEXT_TIMEOUT.
The latter is never used by consumers, so remove support for it.
BIO_CTRL_DGRAM_SET_NEXT_TIMEOUT implicitly depends on struct timeval
being used for timestamps, which we would like to remove. Without this,
the only public API which relies on this is the testing-only
SSL_CTX_set_current_time_cb which is BoringSSL-only and we can change at
our leisure.
