32fbdf2025 Remove anonymous cipher suites.
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.

c0f763b080 Simplify server-side ECDH curve selection.
There's multiple sets of APIs for selecting the curve. Fold away
SSL_OP_SINGLE_ECDH_USE as failing to set it is either a no-op or a bug. With
that gone, the consumer only needs to control the selection of a curve, with
key generation from then on being uniform. Also clean up the interaction
between the three API modes in s3_srvr.c; they were already mutually exclusive
due to tls1_check_ec_tmp_key.

This also removes all callers of EC_KEY_dup (and thus CRYPTO_dup_ex_data)
within the library.

65226257c1 Add SSL_CIPHER_get_rfc_name.
OpenSSL's internal names for the ciphers are not the standard ones and are not
easy to consistently map to the standard ones. Add an API to get the real names
out. (WebRTC wants an API to get the standard names out.)

Also change some incorrect flags on SHA-256 TLS 1.2 ciphers;
SSL_HANDSHAKE_MAC_DEFAULT and SSL_HANDSHAKE_MAC_SHA256 are the same after TLS
1.2. A TLS 1.2 cipher should be tagged explicitly with SHA-256. (This avoids
tripping a check in SSL_CIPHER_get_rfc_name which asserts that default-hash
ciphers only ever use SHA-1 or MD5 for the bulk cipher MAC.)

ccf74f8085 Revise SSL_cutthrough_complete and SSL_in_init.
This makes the following changes:

- SSL_cutthrough_complete no longer rederives whether cutthrough happened and
  just maintains a handshake bit.

- SSL_in_init no longer returns true if we are False Starting but haven't
  completed the handshake. That logic was awkward as it depended on querying
  in_read_app_data to force SSL_read to flush the entire handshake. Defaulting
  SSL_in_init to continue querying the full handshake and special-casing
  SSL_write is better. E.g. the check in bidirectional SSL_shutdown wants to know
  if we're in a handshake. No internal consumer of
  SSL_MODE_HANDSHAKE_CUTTHROUGH ever queries SSL_in_init directly.

- in_read_app_data is gone now that the final use is dead.

e820df9371 Forbid interleaving between application data and handshake protocols.
This is the source of much of renegotiation's complexity, and of OpenSSL's
implementation of it. In practice, we only care about renegotiation because of
the client auth hack. There, we can safely assume that no server will send
application data between sending the HelloRequest and completing the handshake.

ea72bd0b60 Implement all TLS ciphers with stateful AEADs.
The EVP_CIPHER codepath should no longer be used with TLS. It still exists for
DTLS and SSLv3. The AEAD construction in TLS does not allow for
variable-overhead AEADs, so stateful AEADs do not include the length in the ad
parameter. Rather the AEADs internally append the unpadded length once it is
known. EVP_aead_rc4_md5_tls is modified to account for this.

Tests are added (and RC4-MD5's regenerated) for each of the new AEADs. The
cipher tests are all moved into crypto/cipher/test because there's now a lot of
them and they clutter the directory listing.

In ssl/, the stateful AEAD logic is also modified to account for stateful AEADs
with a fixed IV component, and for AEADs which use a random nonce (for the
explicit-IV CBC mode ciphers).

The new implementation fixes a bug/quirk in stateless CBC mode ciphers where
the fixed IV portion of the keyblock was generated regardless. This is at the
end, so it's only relevant for EAP-TLS which generates a MSK from the end of
the key block.

62fd16283a Implement SSL_clear with ssl_new and ssl_free.
State on s3 gets freed in both ssl3_clear and ssl3_free. Considate to just
ssl3_free. This replaces the (SSL,ssl,ssl3)_clear calls in (SSL,ssl,ssl3)_new
with the state that was initialized. This results in a little code duplication
between SSL_new and SSL_clear because state is on the wrong object. I've just
left TODOs for now; some of it will need disentangling.

We're far from it, but going forward, separate state between s and s->s3 as:

- s contains configuration state, DTLS or TLS. It is initialized from SSL_CTX,
  configurable directly afterwards, and preserved across SSL_clear calls.
  (Including when it's implicitly set as part of a handshake callback.)

- Connection state hangs off s->s3 (TLS) and s->d1 (DTLS). It is reset across
  SSL_clear. This should happen naturally out of a ssl_free/ssl_new pair.

The goal is to avoid needing separate initialize and reset code for anything;
the point any particular state is reset is the point its owning context is
destroyed and recreated.

e4824e8af0 Add outgoing messages to the handshake hash at set_handshake_header.
This avoids needing a should_add_to_finished_hash boolean on do_write. The
logic in do_write was a little awkward because do_write would be called
multiple times if the write took several iterations. This also gets complex if
DTLS retransmits are involved. (At a glance, it's not obvious the
BIO_CTRL_DGRAM_MTU_EXCEEDED case actually works.)

Doing it as the handshake message is being prepared avoids this concern. It
also gives a natural point for the extended master secret logic which needs to
do work after the finished hash has been sampled.

As a bonus, we can remove s->d1->retransmitting which was only used to deal
with this issue.

protocol-specific. This finally removes all the version-specific portions of
SSL_METHOD but the version tag itself.

(SSL3_ENC_METHOD's version-specific bits themselves can probably be handled by
tracking a canonicalized protocol version. It would simplify version
comparisons anyway. The one catch is SSLv3 has a very different table. But
that's a cleanup for future. Then again, perhaps a version-specific method
table swap somewhere will be useful later for TLS 1.3.)

7e23746dd4 Remove redundant SSL_ST_BEFORE-related checks.
SSL_ST_BEFORE isn't a possible state anymore. It seems this state meant the
side wasn't known, back in the early SSLeay days. Now upstream guesses
(sometimes incorrectly with generic methods), and we don't initialize until
later. SSL_shutdown also doesn't bother to call ssl3_shutdown at all if the
side isn't initialized and SSL_ST_BEFORE isn't the uninitialized state, which
seems a much more sensible arrangement.

Likewise, because bare SSL_ST_BEFOREs no longer exist, SSL_in_init implies
SSL_in_before and there is no need to check both.

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.

ff42cc1eac Fix FALLBACK_SCSV, Channel ID, OCSP stapling, and SCTs with the generic method.
s->server's value isn't final until SSL_connect or SSL_accept is called when
using the generic SSLv23_method or DTLS_method rather than the version-locked

It would be nicer if the generic methods were gone and an SSL* could know from
creation which half it's destined for. Unfortunately, there's a lot of code
that uses those generic methods, so we probably can't get rid of them. If they
have to stay, it seems better to standardize on only having those, rather than
support both, even if standardizing on the side-specific ones would be
preferable.

It doesn't depend on the cipher now that export ciphers are gone. It need only

So all the configuration-based checks are in one place, change the input
parameter from CERT to SSL and move the PSK and ECDHE checks to the mask
computation. This avoids having to evaluate the temporary EC key for each
cipher.

The remaining uses are on the client which uses them differently (disabled
features rather than enabled ones). Those too may as well be local variables,
so leave a TODO.

6c7aed048c Client-side OCSP stapling support.
Remove the old implementation which was excessively general. This mirrors the
SCT support and adds a single boolean flag to request an OCSP response with no
responder IDs, extensions, or frills. The response, if received, is stored on
the SSL_SESSION so that it is available for (re)validation on session
resumption; Chromium revalidates the saved auth parameters on resume.

Server support is unimplemented for now. This API will also need to be adjusted
in the future if we implement RFC 6961.

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.

f4501347c9 Remove default_timeout hook.
Of the remaining implementations left, ssl3_, dtls1_, and ssl23_, dtls1_ is
redundant and can be folded into ssl3_. ssl23_ actually isn't; it sets 5
minutes rather than 2 hours. Two hours seems to be what everything else uses
and seems a saner default. Most consumers seem to override it anyway
(SSL_CTX_set_timeout). But it is a behavior change.

The method is called at two points:
- SSL_get_default_timeout
- SSL_CTX_new

Incidentally, the latter call actually makes the former never called internally
and the value it returns a lie. SSL_get_default_timeout returns the default
timeout of the /current/ method, but in ssl_get_new_session, the timeout is
shadowed by session_timeout on the context. That is initialized when
SSL_CTX_new is called. So, unless you go out of your way to
SSL_CTX_set_timeout(0), it always overrides. (And it actually used to a
difference because, for SSL23, the SSL_CTX's method is SSL23, but, when session
creation happens, the SSL's method is the version-specific one.)

072334d943 Consistently use uint16_t for curve IDs.
Don't retain curve IDs in serialized form; serialization only happens when
writing and reading from the wire. The internal representation is a uint16_t
which matches the range of the value and avoids all the checks for the first
byte being 0.

This also fixes a bug in tls1_check_ec_tmp_key's suite B logic; the || should
have been &&, though now it's gone.

This doesn't relieve some of the other assumptions about curve IDs:
tls1_set_curves still assumes that all curve IDs are under 32, and
tls1_ec_curve_id2nid still assumes 0 is not a valid curve ID. Add a
compile-time assert and a comment to document this. We're up to 28 now, so this
may well need to be revised sooner or later.

Remove SSL_get_shared_curve as it's new and unused API, using it in a loop is
O(N^3), and lets us simplify a function.

With other handshake state moved there, hopefully we can reset that state in
one go and possibly not even maintain it when there is no handshake in
progress.  Rather than currently where we sometimes confused connection state
and handshake state and have to reset as appropriate on renegotiate.

While I'm here, document the fields and name them something more useful than

5c57c60beb Deprecate SSL_get_client_certificate_types.
OpenSSL added SSL_get0_certificate_types and fixed the truncation (and
subsequent parse error) by adding an alternate copy of the data.
http://git.openssl.org/gitweb/?p=openssl.git;a=commit;h=9f27b1eec3175305e62eed87faa80e231f319ca0

Make SSL_get_client_certificate_types call SSL_get0_certificate_types to query
the new list. Remove when Chromium is switched over.

Also remove a now unnecessary cast because SSL_get_client_certificate_types
fixed the type of tmp.ctypes. Further fix it to use a size_t and match the
cert_st copy OpenSSL added.

BUG=388000

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.

b6333d600e Return per-certificate chain if extra chain is NULL.
If an application calls the macro SSL_CTX_get_extra_chain_certs
return either the old "shared" extra certificates or those associated
with the current certificate.

This means applications which call SSL_CTX_use_certificate_chain_file
and retrieve the additional chain using SSL_CTX_get_extra_chain_certs
will still work. An application which only wants to check the shared
extra certificates can call the new macro
SSL_CTX_get_extra_chain_certs_only

858a88daf2 Equal preference cipher groups.
This change implements equal-preference groups of cipher suites. This
allows, for example, a server to prefer one of AES-GCM or ChaCha20
ciphers, but to allow the client to pick which one. When coupled with
clients that will boost AES-GCM in their preferences when AES-NI is
present, this allows us to use AES-GCM when the hardware exists and
ChaCha20 otherwise.

(Called "cut through" for historical reasons in this patch.)

Enables SSL3+ clients to send application data immediately following the
Finished message even when negotiating full-handshakes.  With this
patch, clients can negotiate SSL connections in 1-RTT even when
performing full-handshakes.
