5b220ee70d Add APIs to query authentication properties of SSL_SESSIONs.
This is so Chromium can verify the session before offering it, rather
than doing it after the handshake (at which point it's too late to punt
the session) as we do today. This should, in turn, allow us to finally
verify certificates off a callback and order it correctly relative to
CertificateRequest in TLS 1.3.

(It will also order "correctly" in TLS 1.2, but this is useless. TLS 1.2
does not bind the CertificateRequest to the certificate at the point the
client needs to act on it.)

103ed08549 Implement legacy OCSP APIs for libssl.
Previously, we'd omitted OpenSSL's OCSP APIs because they depend on a
complex OCSP mechanism and encourage the the unreliable server behavior
that hampers using OCSP stapling to fix revocation today. (OCSP
responses should not be fetched on-demand on a callback. They should be
managed like other server credentials and refreshed eagerly, so
temporary CA outage does not translate to loss of OCSP.)

But most of the APIs are byte-oriented anyway, so they're easy to
support. Intentionally omit the one that takes a bunch of OCSP_RESPIDs.

The callback is benign on the client (an artifact of OpenSSL reading
OCSP and verifying certificates in the wrong order). On the server, it
encourages unreliability, but pyOpenSSL/cryptography.io depends on this.
Dcument that this is only for compatibility with legacy software.

Also tweak a few things for compatilibility. cryptography.io expects
SSL_CTX_set_read_ahead to return something, SSL_get_server_tmp_key's
signature was wrong, and cryptography.io tries to redefine
SSL_get_server_tmp_key if SSL_CTRL_GET_SERVER_TMP_KEY is missing.

f64c373784 Fix build with GCC 4.9.2 and -Wtype-limits.
gRPC builds on Debian Jessie, which has GCC 4.9.2, and builds with
-Wtype-limits, which makes it warn about code intended for 64-bit
systems when building on 32-bit systems.

We have tried to avoid these issues with Clang previously by guarding
with “sizeof(size_t) > 4”, but this version of GCC isn't smart enough to
figure that out.

Just to avoid unnecessary turbulence, since draft-23 is doomed to die

24 through 27.)

We'd actually checked this already on the Go side, but the spec wants a

This is done by adding two new tagged data types to the shim's
transcript: one for the serialized handoff, and another for the
serialized handback.

Then, the handshake driver in |TLSFuzzer| is modified to be able to
drive a handoff+handback sequence in the same way as was done for
testing: by swapping |BIO|s into additional |SSL| objects.  (If a
particular transcript does not contain a serialized handoff, this is a
no-op.)

6e678eeb6e Remove legacy SHA-2 CBC ciphers.
All CBC ciphers in TLS are broken and insecure. TLS 1.2 introduced
AEAD-based ciphers which avoid their many problems. It also introduced
new CBC ciphers based on HMAC-SHA256 and HMAC-SHA384 that share the same
flaws as the original HMAC-SHA1 ones. These serve no purpose. Old
clients don't support them, they have the highest overhead of all TLS
ciphers, and new clients can use AEADs anyway.

Remove them from libssl. This is the smaller, more easily reverted
portion of the removal. If it survives a week or so, we can unwind a lot
more code elsewhere in libcrypto. This removal will allow us to clear
some indirect calls from crypto/cipher_extra/tls_cbc.c, aligning with
the recommendations here:

https://github.com/HACS-workshop/spectre-mitigations/blob/master/crypto_guidelines.md#2-avoid-indirect-branches-in-constant-time-code

Update-Note: The following cipher suites are removed:
- TLS_RSA_WITH_AES_128_CBC_SHA256
- TLS_RSA_WITH_AES_256_CBC_SHA256
- TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256
- TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA384
- TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256

71666cb87c Allow renego and config shedding to coexist more smoothly.
Chrome needs to support renegotiation at TLS 1.2 + HTTP/1.1, but we're
free to shed the handshake configuration at TLS 1.3 or HTTP/2.

Rather than making config shedding implicitly disable renegotiation,
make the actual shedding dependent on a combination of the two settings.
If config shedding is enabled, but so is renegotiation (including
whether we are a client, etc.), leave the config around. If the
renegotiation setting gets disabled again after the handshake,
re-evaluate and shed the config then.

b7bc80a9a6 SSL_CONFIG: new struct for sheddable handshake configuration.
|SSL_CONFIG| is a container for bits of configuration that are
unneeded after the handshake completes.  By default it is retained for
the life of the |SSL|, but it may be shed at the caller's option by
calling SSL_set_shed_handshake_config().  This is incompatible with
renegotiation, and with SSL_clear().

|SSL_CONFIG| is reachable by |ssl->config| and by |hs->config|.  The
latter is always non-NULL.  To avoid null checks, I've changed the
signature of a number of functions from |SSL*| arguments to
|SSL_HANDSHAKE*| arguments.

When configuration has been shed, setters that touch |SSL_CONFIG|
return an error value if that is possible.  Setters that return |void|
do nothing.

Getters that request |SSL_CONFIG| values will fail with an |assert| if
the configuration has been shed.  When asserts are compiled out, they
will return an error value.

The aim of this commit is to simplify analysis of split-handshakes by
making it obvious that some bits of state have no effects beyond the
handshake.  It also cuts down on memory usage.

Of note: |SSL_CTX| is still reachable after the configuration has been
shed, and a couple things need to be retained only for the sake of
post-handshake hooks.  Perhaps these can be fixed in time.

e28552dec8 Add an API to disable RSA-PSS for certificates.
Chrome uses the platform certificate verifier and thus cannot reliably
expect PSS signatures to work in all configurations. Add an API for the
consumer to inform BoringSSL of this ability. We will then adjust our
advertisements accordingly.

Note that, because TLS 1.2 does not have the signature_algorithms_cert
extension, turning off TLS 1.3 and using this API will stop advertising
RSA-PSS. I believe this is the correct behavior given the semantics of
that code point.

The tests check the various combinations here, as well as checking that
the peer never sends signature_algorithms_cert identical to
signature_algorithms.

c5154f7dbc SSL_serialize_handoff: serialize fewer things.
In the handoff+handback case, bssl_shim.cc creates 3 |SSL| objects:
one to receive the ClientHello, one to receive the handoff, and a
third one to receive the handback.

Before 56986f9, only the first of these received any configuration.
Since that commit, all 3 of them receive the same configuration.  That
means that the handback message no longer needs to serialize as many
things.

N.B. even before 56986f9, not all of the fields were necessary.  For
example, there was no reason to serialize |conf_max_version| and
|conf_min_version| in the handback, so far as I can tell.

This commit is mechanical: it simply removes everything that doesn't
cause any tests to fail.  In the long run, I'll need to carefully
check for two possibilities:

- Knobs that affect the handshake after the server's first message it
  sent.  These are troublesome because that portion of the handshake
  may run on a different |SSL|, depending on whether the handback is
  early or late.

- Getters that may be called post-handshake, and that callers may
  reasonably expect to reflect the value that was used during
  handshake.

(I'm not sure that either case exists!)

e2ab21d194 Use the actual record header, rather than reassembling it.
The last-minute TLS 1.3 change was done partly for consistency with DTLS
1.3, where authenticating the record header is less obviously pointless
than in TLS. There, reconstructing it would be messy. Instead, pass in

assemble its own.

(While I'm here, reorder all the flags so the AD and nonce ones are
grouped together.)

8a1a5daa49 Send the fake session ID in the test suite.
NSS only enables compatibility mode on the server if the client
requested it by way of the session ID. This is slightly off as a client
has no way not to request it when offering a TLS 1.2 session, but it is
in the spec.

So our tests are usable for other stacks, send a fake session ID in the
runner by default. The existing EmptySessionID-TLS13* test asserts that
BoringSSL behaves as we expect it to on empty session IDs too. The
intent is that NSS will disable that test but can otherwise leave the
rest enabled.

8df8e64205 Record whether dummy PQ padding was used.
On reflection, I think we'll need to note whether dummy PQ padding was
echoed on a given connection. Otherwise measurements in Chrome will be
mixed with cases where people have MITM proxies that ignored the
extension, or possibly Google frontends that haven't been updated.

Therefore this change will be used to filter latency measurements in
Chrome to only include those where the extension was echoed and we'll
measure at levels of 1 byte (for control), 400 bytes, and 1100 bytes.

This also makes it an error if the server didn't echo an extension of
the same length as was sent.

The extension is sent (and echoed) for both full and resumption
handshakes. This is intended to mirror the overhead of TLS 1.3 (even
when using TLS 1.2), as a resumption in TLS 1.3 still does a fresh key
agreement.

c03ecb93a2 Remove SSLv3_method and friends.
SSLv3_method, SSLv3_client_method, and SSLv3_server_method produce
SSL_CTXs which fail every handshake. They appear no longer necessary for
compatibility, so remove them.

SSLv3 is still accessible to callers who explicitly re-enable SSLv3 on a
TLS_method, but that will be removed completely later this year.
Meanwhile, clear out a weird hack we had here.

Update-Note: I believe there are no more callers of these functions. Any
   that were were already non-functional as these methods haven't been
   unable to handshake for a while now.

1bf2337fe1 Reject compressed ECDH coordinates in TLS.
We don't advertise compressed coordinates (and point format negotiation
was deprecated in TLS 1.3), so reject them. Both Internet Explorer and
Firefox appear to reject them already.

Later I hope to add an easier to use ECDH API that acts on bytes, not
EC_POINT. This clears the way for that API to only accept uncompressed
coordinates. Compressed coordinates never got deployed over NIST curves,
for better or worse. At this point, there is no sense in changing that
as new protocols should use curve25519.

fa65113400 Push an error if custom private keys fail.
The private key callback may not push one of its own (it's possible to
register a custom error library and whatnot, but this is tedious). If
the callback does not push any, we report SSL_ERROR_SYSCALL. This is not
completely wrong, as "syscall" really means "I don't know, something you
gave me, probably the BIO, failed so I assume you know what happened",
but most callers just check errno. And indeed cert_cb pushes its own
error, so this probably should as well.

Update-Note: Custom private key callbacks which push an error code on
    failure will report both that error followed by
    SSL_R_PRIVATE_KEY_OPERATION_FAILED. Callbacks which did not push any
    error will switch from SSL_ERROR_SYSCALL to SSL_ERROR_SSL with
    SSL_R_PRIVATE_KEY_OPERATION_FAILED.

Mono's legacy TLS 1.0 stack, as a server, does not implement any form of
resumption, but blindly echos the ClientHello session ID in the
ServerHello for no particularly good reason.

This is invalid, but due to quirks of how our client checked session ID
equality, we only noticed on the second connection, rather than the
first. Flaky failures do no one any good, so break deterministically on
the first connection, when we realize something strange is going on.

512a289a8a Add support for dummy PQ padding.
This extension will be used to measure the latency impact of potentially
sending a post-quantum key share by default. At this time it's purely
measuring the impact of the client sending the key share, not the server
replying with a ciphertext.

We could use the existing padding extension for this but that extension
doesn't allow the server to echo it, so we would need a different
extension in the future anyway. Thus we just create one now.

We can assume that modern clients will be using TLS 1.3 by the time that
PQ key-exchange is established and thus the key share will be sent in
all ClientHello messages. However, since TLS 1.3 isn't quite here yet,
this extension is also sent for TLS 1.0–1.2 ClientHellos. The latency
impact should be the same either way.

9770532afa Map NOT_YET_VALID errors to |certificate_expired|.
The language of RFC 5246 is "A certificate has expired or is not
currently valid", which sounds to me like |certificate_expired| should
pertain to any case where the current time is outside the
certificate's validity period.

Along the way, group the |unknown_ca| errors together.

6df6540766 Add a draft TLS 1.3 anti-downgrade signal.
TLS 1.3 includes a server-random-based anti-downgrade signal, as a
workaround for TLS 1.2's ServerKeyExchange signature failing to cover
the entire handshake. However, because TLS 1.3 draft versions are each
doomed to die, we cannot deploy it until the final RFC. (Suppose a
draft-TLS-1.3 client checked the signal and spoke to a final-TLS-1.3
server. The server would correctly negotiate TLS 1.2 and send the
signal. But the client would then break. An anologous situation exists
with reversed roles.)

However, it appears that Cisco devices have non-compliant TLS 1.2
implementations[1] and copy over another server's server-random when
acting as a TLS terminator (client and server back-to-back).

Hopefully they are the only ones doing this. Implement a
measurement-only version with a different value. This sentinel must not
be enforced, but it will tell us whether enforcing it will cause
problems.

It's misnamed but, more importantly, doesn't do anything because the
test client isn't sending early data to begin with. We really need to
make these tests less error-prone to write. With this fix, the test
actually notices if we remove the server-side 0-RTT check.

Also remove MaxEarlyDataSize from the other server tests which
erroneously set it. Any test with sets that was likely copy-and-pasted
incorrectly.

e7c95d91f8 Run TLS 1.3 tests at all variants and fix bugs.
We were only running a random subset of TLS 1.3 tests with variants and
let a lot of bugs through as a result.

- HelloRetryRequest-EmptyCookie wasn't actually testing what we were
  trying to test.

- The second HelloRetryRequest detection needs tweaks in draft-22.

- The empty HelloRetryRequest logic can't be based on non-empty
  extensions in draft-22.

- We weren't sending ChangeCipherSpec correctly in HRR or testing it
  right.

- Rework how runner reads ChangeCipherSpec by setting a flag which
  affects the next readRecord. This cuts down a lot of cases and works
  correctly if the client didn't send early data. (In that case, we
  don't flush CCS until EndOfEarlyData and runner deadlocks waiting for
  the ChangeCipherSpec to arrive.)

This is a wire format change for our existing drafts *only if* records

records continue to be capped at 2^14 bytes of plaintext (or 2^14+1
bytes of TLSInnerPlaintext structure).
