For now, this is the laziest conversion possible. The intent is to just
get the build setup ready so that we can get everything working in our
consumers. The intended end state is:
- The standalone build produces three test targets, one per library:
{crypto,ssl,decrepit}_tests.
- Each FOO_test is made up of:
FOO/**/*_test.cc
crypto/test/gtest_main.cc
test_support
- generate_build_files.py emits variables crypto_test_sources and
ssl_test_sources. These variables are populated with FindCFiles,
looking for *_test.cc.
- The consuming file assembles those variables into the two test targets
(plus decrepit) from there. This avoids having generate_build_files.py
emit actual build rules.
- Our standalone builders, Chromium, and Android just run the top-level
test targets using whatever GTest-based reporting story they have.
In transition, we start by converting one of two tests in each library
to populate the three test targets. Those are added to all_tests.json
and all_tests.go hacked to handle them transparently. This keeps our
standalone builder working.
generate_build_files.py, to start with, populates the new source lists
manually and subtracts them out of the old machinery. We emit both for
the time being. When this change rolls in, we'll write all the build
glue needed to build the GTest-based tests and add it to consumers'
continuous builders.
Next, we'll subsume a file-based test and get the consumers working with
that. (I.e. make sure the GTest targets can depend on a data file.)
Once that's all done, we'll be sure all this will work. At that point,
we start subsuming the remaining tests into the GTest targets and,
asynchronously, rewriting tests to use GTest properly rather than
cursory conversion here.
When all non-GTest tests are gone, the old generate_build_files.py hooks
will be removed, consumers updated to not depend on them, and standalone
builders converted to not rely on all_tests.go, which can then be
removed. (Unless bits end up being needed as a malloc test driver. I'm
thinking we'll want to do something with --gtest_filter.)
As part of this CL, I've bumped the CMake requirements (for
target_include_directories) and added a few suppressions for warnings
that GTest doesn't pass.

OpenSSL includes a leaf certificate in a certificate chain when it's a
client, but doesn't when it's a server. This is also reflected in the
serialisation of sessions.
This change makes the internal semantics consistent: the leaf is always
included in the chain in memory, and never duplicated when serialised.
To maintain the same API, SSL_get_peer_cert_chain will construct a copy
of the chain without the leaf if needed.
Since the serialised format of a client session has changed, an
|is_server| boolean is added to the ASN.1 that defaults to true. Thus
any old client sessions will be parsed as server sessions and (silently)
discarded by a client.

This change adds a STACK_OF(CRYPTO_BUFFER) to an SSL_SESSION which
contains the raw form of the received certificates. The X509-based
members still exist, but their |enc| buffer will alias the
CRYPTO_BUFFERs.
The serialisation format of SSL_SESSIONs is also changed, in a backwards
compatible way. Previously, some sessions would duplicate the leaf
certificate in the certificate chain. These sessions can still be read,
but will be written in a way incompatible with older versions of the
code. This should be fine because the situation where multiple versions
exchange serialised sessions is at the server, and the server doesn't
duplicate the leaf certifiate in the chain anyway.

Due to recent changes, changing the SSL session timeout from cert_cb is
not possible anymore since the new |SSL_SESSION| is initialized *after*
cert_cb is run. The alternative would be using |SSL_CTX_set_timeout| but
the specific |SSL_CTX| could be shared by multiple |SSL|s.
Setting a value on a per-connection basis is useful in case timeouts
need to be calculated dynamically based on specific certificate/domain
information that would be retrieved from inside cert_cb (or other
callbacks).
It would also be possible to set the value to 0 to prevent session
resumption, which is not otherwise doable in the handshake callbacks.

The distinction for full handshakes is not meaningful (the timestamp is
currently the start of the handshake), but for renewed sessions, we
currently retain the timestamp of the original issuance.
Instead, when minting or receiving tickets, adjust session->time and
session->timeout so that session->time is the ticket issuance time.
This is still not our final TLS 1.3 behavior (which will need a both
renewable and non-renewable times to honor the server ticket lifetime),
but it gets us closer and unblocks handling ticket_age_add from TLS 1.3
draft 18 and sends the correct NewSessionTicket lifetime.
This fixes the ticket lifetime hint which we emit on the server to
mirror the true ticket lifetime. It also fixes the TLS 1.3 server code
to not set the ticket lifetime hint. There is no need to waste ticket
size with it, it is no longer a "hint" in TLS 1.3, and even in the TLS
1.3 code we didn't fill it in on the server.

We currently preferentially sign the largest hash available and

happy with SHA-256 and, all else equal, a smaller hash would be epsilon
more performant. We also currently claim, in TLS 1.3, we prefer P-384

Instead order SHA-256 first, next the larger SHA-2 hashes, and leave
SHA-1 at the bottom. Within a hash, order ECDSA > RSA-PSS > RSA-PKCS1.
This has the added consequence that we will preferentially pair P-256
with SHA-256 in signatures we generate instead of larger hashes that get

Unlike the Scoped* types, bssl::UniquePtr is available to C++ users, and
offered for a large variety of types. The 'extern "C++"' trick is used
to make the C++ bits digestible to C callers that wrap header files in

peer_sigalgs should live on SSL_HANDSHAKE. This both releases a little
bit of memory after the handshake is over and also avoids the bug where
the sigalgs get dropped if SSL_set_SSL_CTX is called at a bad time. See
also upstream's 14e14bf6964965d02ce89805d9de867f000095aa.
This only affects consumers using the old SNI callback and not
select_certificate_cb.
Add a test that the SNI callback works as expected. In doing so, add an
SSL_CTX version of the signing preferences API. This is a property of
the cert/key pair (really just the key) and should be tied to that. This
makes it a bit easier to have the regression test work with TLS 1.2 too.

SSL_set_bio is a nightmare.
In f715c42322, we noticed that, among
other problems, SSL_set_bio's actual behavior did not match how
SSL_set_rfd was calling it due to an asymmetry in the rbio/wbio
handling. This resulted in SSL_set_fd/SSL_set_rfd calls to crash. We
decided that SSL_set_rfd's believed semantics were definitive and
changed SSL_set_bio.
Upstream, in 65e2d672548e7c4bcb28f1c5c835362830b1745b, decided that
SSL_set_bio's behavior, asymmetry and all, was definitive and that the
SSL_set_rfd crash was a bug in SSL_set_rfd. Accordingly, they switched
the fd callers to use the side-specific setters, new in 1.1.0.
Align with upstream's behavior and add tests for all of SSL_set_bio's
insanity. Also export the new side-specific setters in anticipation of
wanting to be mostly compatible with OpenSSL 1.1.0.

To prevent configuration/established session confusion, the handshake
session state is separated into the configured session (ssl->session)
and the newly created session (ssl->s3->new_session). Upon conclusion of
the handshake, the finalized session is stored
in (ssl->s3->established_session). During the handshake, any requests
for the session (SSL_get_session) return a non-resumable session, to
prevent resumption of a partially filled session. Sessions should only
be cached upon the completion of the full handshake, using the resulting
established_session. The semantics of accessors on the session are
maintained mid-renego.

OpenSSL's SSL_OP_NO_* flags allow discontinuous version ranges. This is a
nuisance for two reasons. First it makes it unnecessarily difficult to answer
"are any versions below TLS 1.3 enabled?". Second the protocol does not allow
discontinuous version ranges on the client anyway. OpenSSL instead picks the
first continous range of enabled versions on the client, but not the server.
This is bizarrely inconsistent. It also doesn't quite do this as the
ClientHello sending logic does this, but not the ServerHello processing logic.
So we actually break some invariants slightly. The logic is also cumbersome in
DTLS which kindly inverts the comparison logic.
First, switch min_version/max_version's storage to normalized versions. Next
replace all the ad-hoc version-related functions with a single
ssl_get_version_range function. Client and server now consistently pick a
contiguous range of versions. Note this is a slight behavior change for
servers. Version-range-sensitive logic is rewritten to use this new function.

SSL_set_bio has some rather complex ownership story because whether rbio/wbio
are both owning depends on whether they are equal. Moreover, whether
SSL_set_bio(ssl, rbio, wbio) frees ssl->rbio depends on whether rbio is the
existing rbio or not. The current logic doesn't even get it right; see tests.
Simplify this. First, rbio and wbio are always owning. All the weird ownership
cases which we're stuck with for compatibility will live in SSL_set_bio. It
will internally BIO_up_ref if necessary and appropriately no-op the left or
right side as needed. It will then call more well-behaved ssl_set_rbio or
ssl_set_wbio functions as necessary.

The internal session cache is keyed on session ID, so this is completely
useless for clients (indeed we never look it up internally). Along the way,
tidy up ssl_update_cache to be more readable. The slight behavior change is
that SSL_CTX_add_session's return code no longer controls the external
callback. It's not clear to me what that could have accomplished. (It can only
fail on allocation error. We only call it for new sessions, so the duplicate
case is impossible.)
The one thing of value the internal cache might have provided is managing the
timeout. The SSL_CTX_flush_sessions logic would flip the not_resumable bit and
cause us not to offer expired sessions (modulo SSL_CTX_flush_sessions's delay
and any discrepancies between the two caches). Instead, just check expiration
when deciding whether or not to offer a session.
This way clients that set SSL_SESS_CACHE_CLIENT blindly don't accidentally
consume gobs of memory.

Move cert_chain to the SSL_SESSION. Now everything on an SSL_SESSION is
properly serialized. The cert_chain field is, unfortunately, messed up
since it means different things between client and server.
There exists code which calls SSL_get_peer_cert_chain as both client and
server and assumes the existing semantics for each. Since that function
doesn't return a newly-allocated STACK_OF(X509), normalizing between the
two formats is a nuisance (we'd either need to store both cert_chain and
cert_chain_full on the SSL_SESSION or create one of the two variants
on-demand and stash it into the SSL).
This CL does not resolve this and retains the client/server difference
in SSL_SESSION. The SSL_SESSION serialization is a little inefficient
(two copies of the leaf certificate) for a client, but clients don't
typically serialize sessions. Should we wish to resolve it in the
future, we can use a different tag number. Because this was historically
unserialized, existing code must already allow for cert_chain not being
preserved across i2d/d2i.
In keeping with the semantics of retain_only_sha256_of_client_certs,
cert_chain is not retained when that flag is set.

The original OpenSSL implementation did the same. M_ASN1_D2I_Finish checks
this. Forwards compatibility with future sessions with unknown fields is
probably not desirable.

This isn't exhaustive. There are still failures in some tests which probably
ought to get C++'d first.

This will be reverted in a minute. The bots should run both suites of tests and
report the names of all failing tests in the summary.

Rather than shoehorn real ciphers and cipher aliases into the same type (that's
what cipher->valid is used for), treat them separately. Make
ssl_cipher_apply_rule match ciphers by cipher_id (the parameter was ignored and
we assumed that masks uniquely identify a cipher) and remove the special cases
around zero for all the masks. This requires us to remember which fields
default to 0 and which default to ~0u, but the logic is much clearer.
Finally, now that ciphers and cipher aliases are different, don't process rules
which sum together an actual cipher with cipher aliases. This would AND
together the masks for the alias with the values in the cipher and do something
weird around alg_ssl. (alg_ssl is just weird in general, as everyone trying to
disable SSLv3 in OpenSSL recently discovered.)
With all that, we can finally remove cipher->valid which was always one.

A previous change in BoringSSL renamed ERR_print_errors_fp to
BIO_print_errors_fp as part of refactoring the code to improve the
layering of modules within BoringSSL. Rename it back for better
compatibility with code that was using the function under the original
name. Move its definition back to crypto/err using an implementation
that avoids depending on crypto/bio.

These are the remaining untested cipher suites. Rather than add support in
runner.go, just remove them altogether. Grepping for this is a little tricky,
but nothing enables aNULL (all occurrences disable it), and all occurrences of
["ALL:] seem to be either unused or explicitly disable anonymous ciphers.

SSL_CIPHER_get_rfc_name still returns an allocated string.
