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.

Also fix some DTLS cookie bugs. rcvd_cookie is never referenced after being

cookie verification failed to check the length.

This is the only codepath that allowed a cert_st to be shared between two

even per-handshake state, this probably doesn't work.
Remove the function altogether and don't ref-count cert_st.

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.

PSK identity hint can be stored in SSL_CTX and in SSL/SSL_SESSION,
similar to other TLS parameters, with the value in SSL/SSL_SESSION
taking precedence over the one in SSL_CTX. The value in SSL_CTX is
shared (used as the default) between all SSL instances associated
with that SSL_CTX, whereas the value in SSL/SSL_SESSION is confined
to that particular TLS/SSL connection/session.
The existing implementation of TLS-PSK does not correctly distinguish
between PSK identity hint in SSL_CTX and in SSL/SSL_SESSION. This
change fixes these issues:
1. SSL_use_psk_identity_hint does nothing and returns "success" when
the SSL object does not have an associated SSL_SESSION.
2. On the client, the hint in SSL_CTX (which is shared between
multiple SSL instances) is overwritten with the hint received from
server or reset to NULL if no hint was received.
3. On the client, psk_client_callback is invoked with the hint from
SSL_CTX rather than from current SSL/SSL_SESSION (i.e., the one
received from the server). Issue #2 above masks this issue.
4. On the server, the hint in SSL/SSL_SESSION is ignored and the hint
from SSL_CTX is sent to the client.
5. On the server, the hint in SSL/SSL_SESSION is reset to the one in
SSL_CTX after the ClientKeyExchange message step.
This change fixes the issues by:
* Adding storage for the hint in the SSL object. The idea being that
the hint in the associated SSL_SESSION takes precedence.
* Reading the hint during the handshake only from the associated
SSL_SESSION object.
* Initializing the hint in SSL object with the one from the SSL_CTX
object.
* Initializing the hint in SSL_SESSION object with the one from the
SSL object.
* Making SSL_use_psk_identity_hint and SSL_get_psk_identity_hint
set/get the hint to/from SSL_SESSION associated with the provided
SSL object, or, if no SSL_SESSION is available, set/get the hint
to/from the provided SSL object.
* Removing code which resets the hint during handshake.
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.
This patch adds support for a different cipher list when the connection
is using TLS 1.1. This is intended to support the case where we want to
use AES with >= TLS 1.1 clients but RC4 otherwise because of the BEAST
attack.
(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.
Initial fork from f2d678e6e89b6508147086610e985d4e8416e867 (1.0.2 beta).
(This change contains substantial changes from the original and
effectively starts a new history.)
