0b1bb12ce8 Push the SSL_CTX session_timeout zero logic up.
This special-case is almost unexposed (the timeout is initialized to the
default) except if the caller calls SSL_CTX_set_timeout(0). Preserve
that behavior by mapping 0 to SSL_DEFAULT_SESSION_TIMEOUT in
SSL_CTX_set_timeout but simplify the internal state.

0efa7592e3 dispatch_alert is not an incidental write.
It is impossible to have to call dispatch_alert when writing application
data. Now that we don't send warning alerts through ssl3_send_alert, all
alerts are closure alerts, which means attempts to write will fail.

This prunes a lot of dead code, avoiding the re-entrancy in the write
path. With that gone, tracking alert_dispatch is much more
straightforward.

The recent CRYPTO_BUFFER changes meant that |X509| objects passed to
SSL_CTX_add_extra_chain_cert would be |free|ed immediately. However,
some third-party code (at least serf and curl) continue to use the

In order to unblock things, keep the past |X509| around for a while to
paper over the issues with those libraries while we try and upstream

3f38d80b2f Add CFI information to the x86-64 X25519 asm.
This change serves to check that all our consumers can process assembly
with CFI directives in it.

For the first change I picked a file that's not perlasm to keep things
slightly simplier, but that might have been a mistake:

DJB's tooling always aligns the stack to 32 bytes and it's not possible
to express this in DWARF format (without using a register to store the
old stack pointer).

Since none of the functions here appear to care about that alignment, I
removed it from each of them. I also trimmed the set of saved registers
where possible and used the redzone for functions that didn't need much
stack.

Overall, this appears to have slightly improved the performance (by
about 0.7%):

f71036e4e3 Remove ssl_hash_message_t from ssl_get_message.
Move to explicit hashing everywhere, matching TLS 1.2 with TLS 1.3. The
ssl_get_message calls between all the handshake states are now all
uniform so, when we're ready, we can rewire the TLS 1.2 state machine to
look like the TLS 1.3 one. (ssl_get_message calls become an
ssl_hs_read_message transition, reuse_message becomes an ssl_hs_ok
transition.)

This avoids some nuisance in processing the ServerHello at the 1.2 / 1.3
transition.

The downside of explicit hashing is we may forget to hash something, but
this will fail to interop with our tests and anyone else, so we should
be able to catch it.

1a444daca6 Detach V2ClientHello hashing hack from ssl_hash_message_t.
This is kind of annoying (even new state is needed to keep the layering
right). As part of aligning the read paths of the TLS 1.2 and TLS 1.3
state machine, we'll want to move to states calling
ssl_hash_current_message when the process the message, rather than when
the message is read. Right now the TLS 1.2 optional message story
(reuse_message) depends on all messages preceded by an optional message
using ssl_hash_message. For instance, if TLS 1.2 decided to place
CertificateStatus before ServerKeyExchange, we would not be able to
handle it.

However, V2ClientHello, by being handled in the message layer, relies on
ssl_get_message-driven hashing to replace the usual ClientHello hash
with a hash of something custom. This switches things so rather than
ClientHellos being always pre-hashed by the message layer, simulated
ClientHellos no-op ssl_hash_current_message.

This just replaces one hack with another (V2ClientHello is inherently
nasty), but this hack should be more compatible with future plans.

276b7e8127 Move optional message type checks out of ssl_get_message.
This aligns the TLS 1.2 state machine closer with the TLS 1.3 state
machine. This is more work for the handshake, but ultimately the
plan is to take the ssl_get_message call out of the handshake (so it is
just the state machine rather than calling into BIO), so the parameters
need to be folded out as in TLS 1.3.

The WrongMessageType-* family of tests should make sure we don't miss
one of these.

42e3e191e4 Restore mapping BIO_flush errors to -1.
This was originally changed so that flush_flight could forward BIO_write
errors as-is, but we can and probably should still map BIO_flush errors.
This is unlikely to matter (every relevant BIO likely just has a no-op
flush which returns one), but, e.g., our file BIO returns 0, not -1, on
error.

We possibly should also be mapping BIO_write errors, but I'll leave that
alone for now. It's primarily BIO_read where the BIO return value must
be preserved due to error vs. EOF.

(We probably can just remove the BIO_flush calls altogether, but since
the buffer BIO forwarded the flush signal it would be a user-visible
behavior change to confirm.)

This change converts the |CERT| struct to holding certificates as binary

event that someone asks us for a non-owning pointer to the parsed leaf

Next steps:
  * Move more functions in to ssl_x509.c
  * Create an X509_OPS struct of function pointers that will hang off
    the |SSL_METHOD| to abstract out the current calls to crypto/x509

9b16066654 Ignore 0-RTT-capable tickets unless enabled.
Until we've gotten it fully working, we should not mint any of these
SSL_SESSIONs, to avoid constraining future versions of our client code.

Notably, if any of our TLS 1.3 clients today serialized sessions, we
would need to rev the serialization format. Without opting into 0-RTT, a
TLS 1.3 client will create SSL_SESSIONs tagged as 0-RTT-capable but
missing important fields (ALPN, etc.). When that serialized session
makes its way to a future version of our client code, it would disagree
with the server about the ALPN value stored in the ticket and cause
interop failures.

I believe the only client code enabling TLS 1.3 right now is Chrome, and
the window is small, so it should be fine. But fix this now before it
becomes a problem.

pending data consists of encrypting the record into the buffer. This
effectively reimplements what the buffer BIO was doing previously, but
this resizes to fit the whole flight.

As part of this, rename all the functions to add to the pending flight
to be more uniform. This CL proposes "add_foo" to add to the pending
flight and "flush_flight" to drain it.

We add an add_alert hook for alerts but, for now, only the SSL 3.0
warning alert (sent mid-handshake) uses this mechanism.  Later work will
push this down to the rest of the write path so closure alerts use it
too, as in DTLS. The intended end state is that all the ssl_buffer.c and
wpend_ret logic will only be used for application data and eventually
optionally replaced by the in-place API, while all "incidental" data
will be handled internally.

For now, the two buffers are mutually exclusive. Moving closure alerts
to "incidentals" will change this, but flushing application data early
is tricky due to wpend_ret. (If we call ssl_write_buffer_flush,
do_ssl3_write doesn't realize it still has a wpend_ret to replay.) That
too is all left alone in this change.

To keep the diff down, write_message is retained for now and will be
removed from the state machines in a follow-up change.

1a999cf54d Don't use the buffer BIO in DTLS.
Instead, "writing" a message merely adds it to the outgoing_messages
structure. The code to write the flight then loops over it all and now
shares code with retransmission. The verbs here are all a little odd,
but they'll be fixed in later commits.

In doing so, this fixes a slight miscalculation of the record-layer
overhead when retransmitting a flight that spans two epochs. (We'd use
the encrypted epoch's overhead for the unencrypted epoch.)

8d5f9da2e3 Abstract away BIO_flush calls in the handshake.
This is the first part to removing the buffer BIO. The eventual end
state is the SSL_PROTOCOL_METHOD is responsible for maintaining one
flight's worth of messages. In TLS, it will just be a buffer containing
the flight's ciphertext. In DTLS, it's the existing structure for
retransmit purposes. There will be hooks:

- add_message (synchronous)
- add_change_cipher_spec (synchronous)
- add_warning_alert (synchronous; needed until we lose SSLv3 client auth
  and TLS 1.3 draft 18; draft 19 will switch end_of_early_data to a
  handshake message)
- write_flight (BIO; flush_flight will be renamed to this)

This also preserves the exact return value of BIO_flush. Eventually all
the BIO_write calls will be hidden behind BIO_flush to, to be consistent
with other BIO-based calls, preserve the return value.

8d56558031 Optimized Seal/Open routines for ChaCha20-Poly1305 for x86-64
This is basically the same implementation I wrote for Go

The Go implementation:
https://github.com/golang/crypto/blob/master/chacha20poly1305/chacha20poly1305_amd64.s
The Cloudflare patch for OpenSSL:
https://github.com/cloudflare/sslconfig/blob/master/patches/openssl__chacha20_poly1305_draft_and_rfc_ossl102j.patch

The Seal/Open is only available for the new version, the old one uses
the bundled Poly1305, and the existing ChaCha20 implementations

The benefits of this code, compared to the optimized code currently
disabled in BoringSSL:

* Passes test vectors
* Faster performance: The AVX2 code (on Haswell), is 55% faster for 16B,
  15% for 1350 and 6% for 8192 byte buffers
* Even faster on pre-AVX2 CPUs

Feel free to put whatever license, etc. is appropriate, under the
existing CLA.

Benchmarks are for 16/1350/8192 chunk sizes and given in MB/s:

Before (Ivy Bridge): 34.2   589.5  739.4
After:               68.4   692.1  799.4

966284337d Do a cursory conversion of a few tests to GTest.
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.
