9d0847ae6d Add some missing error failure checks.
Found while diagnosing some crashes and hangs in the malloc tests. This (and
the follow-up) get us further but does not quite let the malloc tests pass
quietly, even without valgrind. DTLS silently ignores some malloc failures
(confusion with silently dropping bad packets) which then translate to hangs.

a54e2e85ee Remove server-side HelloVerifyRequest support.
I found no users of this. We can restore it if needbe, but I don't expect
anyone to find it useful in its current form. The API is suspect for the same
reasons DTLSv1_listen was. An SSL object is stateful and assumes you already
have the endpoint separated out.

If we ever need it, server-side HelloVerifyRequest and DTLSv1_listen should be
implemented by a separate stateless listener that statelessly handles
cookieless ClientHello + HelloVerifyRequest. Once a ClientHello with a valid
cookie comes in, it sets up a stateful SSL object and passes control along to
that.

95695c8d88 runner: Ignore dtlsFlushHandshake failures.
This is consistent with ignoring writeRecord failures. Without doing this, the
DTLS MinimumVersion test now flakily fails with:

  FAILED (MinimumVersion-Client-TLS12-TLS1-DTLS)
  bad error (wanted ':UNSUPPORTED_PROTOCOL:' / 'remote error: protocol version not supported'): local error 'write unix @: broken pipe', child error 'exit status 2', stdout:
  2092242157:error:1007b1a7:SSL routines:ssl3_get_server_hello:UNSUPPORTED_PROTOCOL:../ssl/s3_clnt.c:783:

This is because the MinimumVersion tests assert on /both/ expectedError and
expectedLocalError. The latter is valuable as it asserts on the alert the peer
returned. (I would like us to add more such assertions to our tests where
appropriate.) However, after we send ServerHello, we also send a few messages
following it. This races with the peer shutdown and we sometimes get EPIPE
before reading the alert.

931ab3484f Fix handshake check when False Start is used with implicit read.
It may take up to two iterations of s->handshake_func before it is safe to
continue. Fortunately, even if anything was using False Start this way
(Chromium doesn't), we don't inherit NSS's security bug. The "redundant" check
in the type match case later on in this function saves us.

Amusingly, the success case still worked before this fix. Even though we fall
through to the post-handshake codepath and get a handshake record while
"expecting" app data, the handshake state machine is still pumped thanks to a
codepath meant for renego!

e0e7d0da68 Initialize the record buffers after the handshake check.
The new V2ClientHello sniff asserts, for safety, that nothing else has
initialized the record layer before it runs. However, OpenSSL allows you to
avoid explicitly calling SSL_connect/SSL_accept and instead let
SSL_read/SSL_write implicitly handshake for you. This check happens at a fairly
low-level in the ssl3_read_bytes function, at which point the record layer has
already been initialized.

Add some tests to ensure this mode works.

(Later we'll lift the handshake check to a higher-level which is probably
simpler.)

afbc63fc2f Simplify DTLS epoch rewind.
SSL_AEAD_CTX ownership is currently too confusing. Instead, rely on the lack of
renego, so the previous epoch always uses the NULL cipher. (Were we to support
DTLS renego, we could keep track of s->d1->last_aead_write_ctx like
s->d1->last_write_sequence, but it isn't worth it.)

Buffered messages also tracked an old s->session, but this is unnecessary. The
s->session NULL check in tls1_enc dates to the OpenSSL initial commit and is
redundant with the aead NULL check.

83f9040339 Add DTLS timeout and retransmit tests.
This extends the packet adaptor protocol to send three commands:
  type command =
    | Packet of []byte
    | Timeout of time.Duration
    | TimeoutAck

When the shim processes a Timeout in BIO_read, it sends TimeoutAck, fails the
BIO_read, returns out of the SSL stack, advances the clock, calls
DTLSv1_handle_timeout, and continues.

If the Go side sends Timeout right between sending handshake flight N and
reading flight N+1, the shim won't read the Timeout until it has sent flight
N+1 (it only processes packet commands in BIO_read), so the TimeoutAck comes
after N+1. Go then drops all packets before the TimeoutAck, thus dropping one
transmit of flight N+1 without having to actually process the packets to
determine the end of the flight. The shim then sees the updated clock, calls
DTLSv1_handle_timeout, and re-sends flight N+1 for Go to process for real.

When dropping packets, Go checks the epoch and increments sequence numbers so
that we can continue to be strict here. This requires tracking the initial
sequence number of the next epoch.

The final Finished message takes an additional special-case to test. DTLS
triggers retransmits on either a timeout or seeing a stale flight. OpenSSL only
implements the former which should be sufficient (and is necessary) EXCEPT for
the final Finished message. If the peer's final Finished message is lost, it
won't be waiting for a message from us, so it won't time out anything. That
retransmit must be triggered on stale message, so we retransmit the Finished
message in Go.

377fc3160c Document DTLS timeout API and add current_time_cb hook.
This is so the tests needn't be sensitive to the clock. It is, unfortunately, a
test-only hook, but the DTLS retransmit/timeout logic more-or-less requires it
currently. Use this hook to, for now, freeze the clock at zero. This makes the
tests deterministic.

It might be worth designing a saner API in the future. The current one,
notably, requires that the caller's clock be compatible with the one we
internally use. It's also not clear whether the caller needs to call
DTLSv1_handle_timeout or can just rely on the state machine doing it internally
(as it does do). But mock clocks are relatively tame and WebRTC wants to
compile against upstream OpenSSL for now, so we're limited in how much new API
we can build.

Later, when SSL_read returns <= 0 (EOF or EWOULDBLOCK), the non-empty error

c67a3ae6ba Drop retransmits in DTLS tests.
BoringSSL currently retransmits non-deterministically on an internal timer
(rather than one supplied externally), so the tests currently fail flakily
depending on timing. Valgrind is a common source for this. We still assume an
in-order and reliable channel, but drop retransmits silently:

- Handshake messages may arrive with old sequence numbers.

- Retransmitted CCS records arrive from the previous epoch.

- We may receive a retransmitted Finished after we believe the handshake has
  completed. (Aside: even in a real implementation, only Finished is possible
  here. Even with out-of-order delivery, retransmitted or reordered messages
  earlier in the handshake come in under a different epoch.)

Note that because DTLS renego and a Finished retransmit are ambiguous at the
record layer[*], this precludes us writing tests for DTLS renego. But DTLS
renego should get removed anyway. As BoringSSL currently implements renego,
this ambiguity is also a source of complexity in the real implementation. (See
the SSL3_MT_FINISHED check in dtls1_read_bytes.)

[*] As a further fun aside, it's also complex if dispatching renego vs Finished
after handshake message reassembly. The spec doesn't directly say the sequence
number is reset across renegos, but it says "The first message each side
transmits in /each/ handshake always has message_seq = 0". This means that such
an implementation needs the handshake message reassembly logic be aware that a
Finished fragment with high sequence number is NOT an out-of-order fragment for
the next handshake.

This CL removes the last of the EVP_CIPHER codepath in ssl/. The dead code is
intentionally not pruned for ease of review, except in DTLS-only code where
adding new logic to support both, only to remove half, would be cumbersome.

Fixes made:
- dtls1_retransmit_state is taught to retain aead_write_ctx rather than
  enc_write_ctx.
- d1_pkt.c reserves space for the variable-length nonce when echoed into the
  packet.
- dtls1_do_write sizes the MTU based on EVP_AEAD max overhead.
- tls1_change_cipher_state_cipher should not free AEAD write contexts in DTLS.
  This matches the (rather confused) ownership for the EVP_CIPHER contexts.
  I've added a TODO to resolve this craziness.

It tests the server side because the Certificate message is large enough to
require fragmentation.

82c9e90a58 Merge SSLv23_method and DTLS_ANY_VERSION.
This makes SSLv23_method go through DTLS_ANY_VERSION's version negotiation
logic. This allows us to get rid of duplicate ClientHello logic. For
compatibility, SSL_METHOD is now split into SSL_PROTOCOL_METHOD and a version.
The legacy version-locked methods set min_version and max_version based this
version field to emulate the original semantics.

As a bonus, we can now handle fragmented ClientHello versions now.

Because SSLv23_method is a silly name, deprecate that too and introduce
TLS_method.

accb454e44 Add min_version tests.
These tests use both APIs. This also modifies the inline version negotiation's
error codes (currently only used for DTLS) to align with SSLv23's error codes.
Note: the peer should send a protocol_version alert which is currently untested
because it's broken.

Upstream would send such an alert if TLS 1.0 was supported but not otherwise,
which is somewhat bizarre. We've actually regressed and never send the alert in
SSLv23. When version negotiation is unified, we'll get the alerts back.

cde8abae14 Merge client/server SSL_METHODs into the generic one.
Supporting both schemes seems pointless. Now that s->server and s->state are
set appropriately late and get_ssl_method is gone, the only difference is that
the client/server ones have non-functional ssl_accept or ssl_connect hooks. We
can't lose the generic ones, so let's unify on that.

Note: this means a static linker will no longer drop the client or server
handshake code if unused by a consumer linking statically. However, Chromium
needs the server half anyway for DTLS and WebRTC, so that's probably a lost
cause. Android also exposes server APIs.

8c88153465 Remove a place where SSL_clear cleans up after client/server confusion.
SSL_clear sets s->state and dtls1_clear sets cookie_len on the server. Setting
cookie_len on the server seems to serve no purpose but to let the callback know
how large the buffer is. This can be done just before calling the callback.

It also avoids a bug where the cookie check can be bypassed, should the server
not specify an app_verify_cookie_cb, by supplying a cookie of all zeros of the
maximum size. (Zero is fine because an empty cookie is rejected.)

The goal here is to avoid needing the SSL_clear calls in the handshake
functions. They are currently needed to fix the cookie_len setting when using
the generic method. (They get set wrong and then flipped back.)

8b8c006564 Fix DTLS_ANY_VERSION and add tests.
This fixes bugs that kept the tests from working:

- Resolve DTLS version and cookie before the session.

- In DTLS_ANY_VERSION, ServerHello should be read with first_packet = 1. This
  is a regression from f2fedefdca. We'll want to
  do the same for TLS, but first let's change this to a boolean has_version in a
  follow-up.

Things not yet fixed:

- DTLS code is not EVP_AEAD-aware. Those ciphers are disabled for now.

- On the client, DTLS_ANY_VERSION creates SSL_SESSIONs with the wrong
  ssl_version. The tests pass because we no longer enforce the match as of
  e37216f56009fbf48c3a1e733b7a546ca6dfc2af. (In fact, we've gone from the server
  ignoring ssl_version and client enforcing to the client mostly ignoring
  ssl_version and the server enforcing.)

- ssl3_send_client_hello's ssl_version check checks for equality against
  s->version rather than >.

e78bfded9f Improve test coverage for server_name extension.
Notably, this would have caught ed8270a55c
(although, apart from staring at code coverage, knowing to set resumeSession on
the server test isn't exactly obvious). Perhaps we should systematically set it
on all extension server tests; ClientHello extension parsing happens after
resumption has been determined and is often sensitive to it.

39ebf53dd3 Check the server did not use a TLS 1.2 cipher suite pre-TLS 1.2.
This check got refactored in OpenSSL 1.0.2 and broke in the process. Fix this
and add a test. Otherwise things like client auth can get slightly confused; it
will try to sign the MD5/SHA-1 hash, but the TLS 1.2 cipher suite may not use
SSL_HANDSHAKE_MAC_DEFAULT, so those digests won't be available.

ede973a89a Tidy up cipher ordering.
To align with what Chrome sends on NSS, remove all 3DES cipher suites except
RSA_WITH_3DES_EDE_CBC_SHA. This avoids having to order a PFS 3DES cipher
against a non-PFS 3DES cipher.

Remove the strength sort which wanted place AES_256_CBC ahead of AES_128_GCM
and is not especially useful (everything under 128 is either 3DES or DES).
Instead, explicitly order all the bulk ciphers. Continue to prefer PFS over
non-PFS and ECDHE over DHE.

This gives the following order in Chromium. We can probably prune it a bit
(DHE_DSS, DH_*) in a follow-up.

8bc38f556a DTLS version negotiation doesn't happen at HelloVerifyRequest.
RFC 6347 changed the meaning of server_version in HelloVerifyRequest. It should
now always be 1.0 with version negotiation not happening until ServerHello. Fix
runner.go logic and remove #if-0'd code in dtls1_get_hello_verify.

Enforce this in the runner for when we get DTLS 1.2 tests.

f2fedefdca Simplify HelloVerifyRequest processing.
Rather than switching the order of the ServerHello and HelloVerifyRequest
states and processing each twice, have the states follow the protocol order.
HelloVerifyRequest reading is optional and ServerHello is strict. Use the
send_cookie bit to determine whether we're expecting a cookie or not.

Fix the dtls1_stop_timer call in these states to consistently hit the end of a
server flight; the previous flight should not be cleared from the retransmit
buffer until the entire next flight is received. That said, OpenSSL doesn't
appear to implement the part where, on receipt of the previous peer flight, the
buffered flight is retransmitted. (With the exception of a SSL3_MT_FINISHED
special-case in dtls1_read_bytes.) So if the peer is also OpenSSL, this doesn't
do anything.

Also fix the DTLS test which wasn't actually asserting that the ClientHello
matched.

83c0bc94d7 Test-only DTLS implementation in runner.go.
Run against openssl s_client and openssl s_server. This seems to work for a
start, although it may need to become cleverer to stress more of BoringSSL's
implementation for test purposes.

In particular, it assumes a reliable, in-order channel. And it requires that
the peer send handshake fragments in order. Retransmit and whatnot are not
implemented. The peer under test will be expected to handle a lossy channel,
but all loss in the channel will be controlled. MAC errors, etc., are fatal.
