Emulate active once in such a way that data recived by the TLS connection process, but not fetch via active once option by the user, can be delivered at next active once before final close.

Fragment reassembling needs to handle that a smaller fragment then sent originally might overlap an earlier received fragment.

Add session_id and remove undocumented ssl:session_info/1 Add client_random, server_random and master_secret, they will not be included in ssl:connection_information/1 as they may affect the connections security if used recklessly.

2017-03-07dtls: 'dtlsv1.2' corresponds to 'tlsv1.2'Ingela Anderton Andin
'dtlsv1.2' should not be included in MIN_DATAGRAM_SUPPORTED_VERSIONS as this is the default when crypto does not have sufficient support for 'tlsv1.2' and 'dtlsv1.2'
2017-03-06dtls: Correct dialyzer spec and postpone inclusion of testIngela Anderton Andin
The new_options_in_accept test is not working yet, however DTLS is still work in progress and we want to make a progress merge to avoid merge conflicts with other progress of the ssl application.
2017-03-06dtls: Erlang distribution over DTLS is not supportedIngela Anderton Andin
Erlang distribution requiers a reliable transport, which udp is not. Maybe could be interesting later when SCTP support is added to DTLS.
2017-03-06dtls: Hibernation and retransmit timersIngela Anderton Andin
Change retransmissions timers to use gen_statem state timeouts. We do not need a retransmission timer in the state connection as data traffic in DTLS over UDP is not retransmitted. If the last flight before transitioning into connection is lost, it will be resent when the peer resends its last flight. This will also make hibernation testing more straight forward. We need more adjustments later to handle a reliable DTLS transport such as SCTP.

2017-03-06dtls: DTLS specific handling of socket and ciphersIngela Anderton Andin
DTLS does not support stream ciphers and needs diffrent handling of the "#ssl_socket{}" handle .

2017-02-21ssl: Always prefer AES over 3DESIngela Anderton Andin
AES256 was preferred over 3DES already, so this only makes sure AES128 is preferred over 3DES also. This changes the default but probably nobody will notice as a better algorithm will be chosen anyhow.

2017-02-08ssl: Avoid SSL/TLS hello format confusionIngela Anderton Andin
Valid SSL 3.0 or TLS hellos might accidentally match SSL 2.0 format (and sometimes the other way around before inspecting data) so we need to match SSL 3.0 and TLS first and only match SSL 2.0 hellos when flag to support it is set.
2017-02-01ssl: Simplify configuration codeIngela Anderton Andin
Use map instead of large tuple, which was not an option when the code was written originally. More simplifications along these lines may be done later to the state record.
2017-02-01ssl: Make sure PEM cache works as intendedIngela Anderton Andin
Move of PEM cache to own process was flawed and not all PEM files where cached properly. We must properly handle both the ditributed and the normal mode of the ssl application.

Changes made to ssl_certificate:validate appear to be preventing CRL validation from happening when an id-ce-extKeyUsage extension is present in the cert before the DistributionPoint extension. https://github.com/erlang/otp/blob/448e8aca77dd29ed5b37d56f0700d24ac26a7243/lib/ssl/src/ssl_certificate.erl#L131 See also ERL-338 and PR-1302
2017-01-19ssl: Move PEM cache to a dedicated processIngela Anderton Andin
The PEM cache handling has proven to be too disruptive of the manager process.
2017-01-17ssl: Handle really big handshake packagesIngela Anderton Andin
If a handshake message is really big it could happen that the ssl process would hang due to failing of requesting more data from the socket. This has been fixed. Also added option to limit max handshake size. It has a default value that should be big enough to handle normal usage and small enough to mitigate DoS attacks.

2016-12-19ssl: Correct terminate behaviourIngela Anderton Andin
When the terminate function is called explicitly, to make guarantees that for instance the reuseaddr option works as expected, we must make sure that the clean up code is not run again when gen_statem calls terminate. This check was broken in the rewrite from gen_fsm to gen_statem. Caused PEM cache errors, that in some cases would cause unexpected connection failures.

2016-12-05ssl: Implement DTLS state machineIngela Anderton Andin
Beta DTLS, not production ready. Only very basically tested, and not everything in the SPEC is implemented and some things are hard coded that should not be, so this implementation can not be consider secure. Refactor "TLS connection state" and socket handling, to facilitate DTLS implementation. Create dtls "listner" (multiplexor) process that spawns DTLS connection process handlers. Handle DTLS fragmentation. Framework for handling retransmissions. Replay Detection is not implemented yet. Alerts currently always handled as in TLS.
2016-11-02Add ECC curve selection order config in TLS serverFred Hebert
As per RFC 4492 Sec 5.1, the preferred order of selection of named curves is based on client preferences. Currently, the SSL application only picks entries according to the absolute order of entries as tracked in a hardcoded list in code. This patch changes things so that the client-specified order is preferred. It also allows a mode where the server can be configured to override the client's preferred order with its own, although the chosen ECC must still be within both lists. The configuration is done through the following options: - `eccs`, shared by clients and servers alike, allows the specification of the supported named curves, in their preferred order, and may eventually support more values for explicit primes and so on. - `honor_ecc_order`, a server-only option, is similar to `honor_cipher_order` and will, by default let the server pick the client-preferred ECC, and otherwise pick the server-preferred one. The default value for `eccs` is the same as before, although the server-chosen ECC now defaults to the client rather than previous choice. A function `ssl:eccs()` has been added that returns the highest supported ECCs for the library.

2016-09-27ssl: Avoid event reorderingIngela Anderton Andin
Several handshake events may be received in the same TLS packet. Then there will be several events pushed to the gen_statems internal queue. New events already in the socket-buffer should not be processed if there are more unprocessed handshake events in next_event queue. We need to handle this in the next_record/1 function.
