dd1ca99da4 Remove X509_get_pubkey_parameters.
It's never called in outside code. This too seems to be a remnant of the DSA
PKIX optional parameter stuff. This is confirmed both by a removed comment and
by the brief documentation at http://www.umich.edu/~x509/ssleay/x509_pkey.html

RFC 5480 does not allow ECDSA keys to be missing parameters, so this logic is
incorrect for ECDSA anyway.  It was also failing to check
EVP_PKEY_copy_parameters' return value. And that logic looks pretty suspect if
you have a chain made up multiple certificate types.

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.

29b186736c Precompute sorted array for error strings.
Previously, error strings were kept in arrays for each subdirectory and
err.c would iterate over them all and insert them at init time to a hash
table.

This means that, even if you have a shared library and lots of processes
using that, each process has ~30KB of private memory from building that
hash table.

This this change, all the error strings are built into a sorted list and
are thus static data. This means that processes can share the error
information and it actually saves binary space because of all the
pointer overhead in the old scheme. Also it saves the time taken
building the hash table at startup.

This removes support for externally-supplied error string data.

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.

The ENGINE code had a concept of a stable-ABI for METHODs, because that
might be a useful thing in the future when people want to have blobs
that wrap PKCS#11 or something.

However, at the moment nobody uses this feature and it didn't work very
well anyway: I hadn't updated |ENGINE_free| to free them all and
|set_method| was copying the methods, but not resetting the |is_static|
flag.

This change removes support for non-static methods. We can always put it
back later if we need.

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.

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.

SHA-1 and SHA-256 don't work like this however because they've never

1681d79ddf Remove ECDH_KDF_X9_62 and associated EVP glue.
Removes a bit of unused code. This effectively reverts upstream's
25af7a5dbc05c7359d1d7f472d50d65a9d876b7e. It's new with OpenSSL 1.0.2 so
nothing can be using it yet. We can restore it with tests if we end up wanting
it later.

(Also I think it might be misnamed. The KDF seems to be defined in X9.63, not
X9.62.)

c61517cb5a Define the error case's output in RSA_message_index_PKCS1_type_2.
The use in s3_srvr.c doesn't care (it doesn't even have to be in bounds), but
it's good to have the value be initialized and not a function of the input.
(The old uninitialized case wasn't hit in s3_srvr.c because of the earlier
bounds check.)

5b082e880d Various documentation fixes.
Add some missing headers and ensure each header has a short description. doc.go
gets confused at declarations that break before the first (, so avoid doing
that. Also skip a/an/deprecated: in markupFirstWord and process pipe words in
the table of contents.

d9778fb418 Guard against small MTUs from the BIO.
Based in part on upstream's cf75017bfd60333ff65edf9840001cd2c49870a3. This
situation really shouldn't be able to happen, but between no static asserts
that the minimum MTU is always large enough and a bug in reseting the MTU later
(to be fixed be a follow-up import from upstream), check these and return a
useful error code.

f3a8b12ac3 Remove SSL_SESSION::cipher_id.
As of our 82b7da271f, an SSL_SESSION created
externally always has a cipher set. Unknown ciphers are rejected early. Prior
to that, an SSL_SESSION would only have a valid cipher or valid cipher_id
depending on whether it came from an internal or external session cache.

See upstream's 6a8afe2201cd888e472e44225d3c9ca5fae1ca62 and
c566205319beeaa196e247400c7eb0c16388372b for more context.

Since we don't get ourselves into this strange situation and s->cipher is now
always valid for established SSL_SESSION objects (the existence of
unestablished SSL_SESSION objects during a handshake is awkward, but something
to deal with later), do away with s->cipher_id altogether. An application
should be able to handle failing to parse an SSL_SESSION instead of parsing it
successfuly but rejecting all resumptions.
