128dbc30f6 Factor out the client max-version logic into a helper function.
Replace the comment with a clearer one and reimplement it much more tidily. The
mask thing was more complicated than was needed.

This slightly changes behavior on the DTLS_ANY_VERSION side in that, if only
one method is enabled, we no longer short-circuit to the version-locked method
early. This "optimization" seems unnecessary.

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.)

c44b1df459 Add test for renego client_version quirk.
In upstream's f4e1169341ad1217e670387db5b0c12d680f95f4, the client_version was
made constant across renegotiations, even if the server negotiated a lower
version. NSS has the same quirk, reportedly for SChannel:

https://code.google.com/p/chromium/codesearch#chromium/src/net/third_party/nss/ssl/ssl3con.c&sq=package:chromium&l=5103

Add a test to ensure we do not regress this.

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 >.

69a01608f3 Add malloc failure tests.
This commit fixes a number of crashes caused by malloc failures. They
were found using the -malloc-test=0 option to runner.go which runs tests
many times, causing a different allocation call to fail in each case.

(This test only works on Linux and only looks for crashes caused by
allocation failures, not memory leaks or other errors.)

This is not the complete set of crashes! More can be found by collecting
core dumps from running with -malloc-test=0.

bdf5e72f50 Don't resume sessions if the negotiated version doesn't match.
All of NSS, upstream OpenSSL, SChannel, and Secure Transport require, on the
client, that the ServerHello version match the session's version on resumption.
OpenSSL's current behavior is incompatible with all of these. Fall back to a
full handshake on the server instead of mismatch.

Add a comment on the client for why we are, as of
30ddb434bf, not currently enforcing the same in
the client.

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.

now always be 1.0 with version negotiation not happening until ServerHello. Fix

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.

98e882ead1 Clean up s23_srvr.c.
ssl23_get_client_hello has lots of remnants of SSLv2 support and remnants of an
even older SSL_OP_NON_EXPORT_FIRST option (see upstream's
d92f0bb6e9ed94ac0c3aa0c939f2565f2ed95935) which complicates the logic.

Split it into three states and move V2ClientHello parsing into its own
function. Port it to CBS and CBB to give bounds checks on the V2ClientHello
parse.

This fixes a minor bug where, if the SSL_accept call in ssl23_get_client_hello
failed, cb would not be NULL'd and SSL_CB_ACCEPT_LOOP would get reported an
extra time.

It also unbreaks the invariant between s->packet, s->packet_length,
s->s3->rbuf.buf, and s->s3->rbuf.offset at the point the switch, although this
was of no consequence because the first ssl3_read_n call passes extend = 0
which resets s->packet and s->packet_length.

It also makes us tolerant to major version bumps in the ClientHello. Add tests
for TLS tolerance of both minor and major version bumps as well as the HTTP
request error codes.

7fdeaf1101 Retry sending record split fragment when SSL write fails.
When the write size was exactly SSL3_RT_MAX_PLAIN_LENGTH+1 and record
splitting is needed, an extra byte would be added to the max size of the
message to be written. This would cause the requested size to not exceed
the max. If the SSL_WANT_WRITE error were returned, the next packet
would not get the extra byte added to the max packet size since
record_split_done is set. Since a different set of arguments
(SSL3_RT_MAX_PLAIN_LENGTH+1 vs SSL3_RT_MAX_PLAIN_LENGTH) would be passed
to do_ssl3_write, it would return an "SSL3_WRITE_PENDING:bad write
retry" error.

To avoid a failure in the opposite direction, the max variable increment
is removed as well. This can happen when SSL_MODE_ENABLE_PARTIAL_WRITE
is not enabled and the call to ssl3_write_bytes contains, e.g., a buffer
of 2*SSL3_RT_MAX_PLAIN_LENGTH, where the first call into do_ssl3_write
succeeds writing the first SSL3_RT_MAX_PLAIN_LENGTH bytes, but writing
the second SSL3_RT_MAX_PLAIN_LENGTH bytes fails. This means the first
time the the second section of SSL3_RT_MAX_PLAIN_LENGTH bytes has called
do_ssl3_write with "max" bytes, but next call to ssl3_write_bytes in
turn calls into do_ssl3_write with "max+1" bytes.

expecting Certificate; the messages expected are determined by the cipher
suite. The ssl3_get_server_public_key call is already guarded.

As the previous test demonstrates, this is safe because of the
ssl3_check_cert_and_algorithm call, but avoid the looseness in the parsing
there.

[*] NB: we don't implement RSA_PSK, and OpenSSL has never implemented it.

This works, but there's enough shared codepaths that it's worth a test to
ensure it stays that way.

in the early callback, to provide test coverage for
SSL_early_callback_ctx_extension_get.

325b5c3667 Fix FallbackSCSV test.
It wasn't actually testing SSL_enable_fallback_scsv, just that not calling it
didn't send an SCSV. Plumb the 'flag' parameter to testCase through and add a
test that asserts it does get sent when expected. (Make it a []string since Go
doesn't distinguish nil string from "" and for flexibility.)

ac61fa379f Implement TLS_FALLBACK_SCSV support for the client.
With this change, calling SSL_enable_fallback_scsv on a client SSL* will
cause the fallback SCSV to be sent.

This is intended to be set when the client is performing TLS fallback
after a failed connection. (This only happens if the application itself
implements this behaviour: OpenSSL does not do fallback automatically.)

The fallback SCSV indicates to the server that it should reject the
connection if the version indicated by the client is less than the
version supported by the server.

See http://tools.ietf.org/html/draft-bmoeller-tls-downgrade-scsv-02.
