2019-01-22ssl: Create hs_envIngela Anderton Andin
We want to decrease the size of the outer state tuple, and gain ease of understanding by better grouping. This is the first step of creating a hs_env (handshake environment) part of the state. This change will be performed gradually to reduce merge conflicts complexity and risk of introducing errors.

2018-12-13ssl: Remove no longer needed functionsIngela Anderton Andin
As the stop wrapper functions are no longer needed after tls_sender that altered the behaviour of the TLS distribution code.
2018-12-13ssl: Fix downgradeIngela Anderton Andin
Both test case and code needed updates to work as intended. Code needed update due to new tls_sender process and the test case gave false positive reusult erarlier probably due to beeing to sloopy in order to avoid timeouts.

2018-11-20ssl: Improve the "start" and "negotiated" statesPéter Dimitrov
This change adds the capability to the TLS 1.3 server to process ClientHello messages and answer with ServerHello. Change-Id: I13f6cfac932574300338e7301c6162252a591c70
2018-11-20ssl: Improve TLS 1.3 state machinePéter Dimitrov
- Use internal event to transition to the first state of the TLS 1.3 state machine. - Add gen_handshake_1_3/4 and gen_info_1_3/4. Change-Id: I17f12110356c7be4a8dddf9a616df7f181b0ef37
2018-11-16ssl: Fix encode/decode of ClientHello (TLS 1.3)Péter Dimitrov
- Fix handling of hello versions. TLS 1.3 ClientHello will use TLS 1.3 encoding. - Fix encoding/decoding of TLS records when record protection has not yet been engaged (NULL cipher). Change-Id: I7511d1a7751f1ec8c2f2f2fb3d21ddf80a3f428b

2018-10-08ssl: ERL-738 - Correct alert handling with new TLS sender processIngela Anderton Andin
With the new TLS sender process, solving ERL-622, TLS ALERTs sent in the connection state must be encrypted and sent by the TLS sender process. This to make sure that the correct encryption state is used to encode the ALERTS. Care must also be taken to ensure a graceful close down behavior both for normal shutdown and downgrading from TLS to TCP. The original TR ERL-738 is verified by cowboy tests, and close down behavior by our tests. However we alas have not been able to yet create a minimal test case for the originating problem. Also it seems it has become less likely that we run in to the TCP delivery problem, that is the guarantee is only on transport level, not application level. Keep work around function in ssl_test_lib but we can have better test as long as we do not get to much wobbling tests.
2018-09-27ssl: Generalize extensions handlingIngela Anderton Andin
As TLS 1.3 introduces more extensions in other places than in hello messages we like to have generalize extension handling encode/decode with some hello wrappers. Also extend property tests of handshake encod/decode

2018-09-20ssl: Move link to correct processIngela Anderton Andin
The link should be between the connection process and the tls_sender process. But the start of the tls_sender process needs to be done by the process that also starts the connection process in order to correctly create the opaque #ssl_socket{}.

2018-08-27ssl: Improve close handlingIngela Anderton Andin
We want to make sure that the sender process that may get stuck in prim_inet:send will die if the tls_connection process is terminated. And we also like to make sure that it terminates as gracefully as possible. So when the tls_connection process dies it spawns a killer process that will brutaly kill the sender if it is unresponsive and does not terminate due to its monitor of the tls_connetion process triggering. When the sender process also acts as distribution controller it may also have other processess that it is linked with that it should bring down or that could bring the connection down.
2018-08-27ssl: Adopt distribution over TLS to use new sender processIngela Anderton Andin
2018-08-27ssl: Add new sender process for TLS state machineIngela Anderton Andin
Separate sending and receiving when using TCP as transport as prim_inet:send may block which in turn may result in a deadlock between two Erlang processes communicating over TLS, this is especially likely to happen when running Erlang distribution over TLS.
2018-07-19ssl: Fix handling of TLS record versionsPéter Dimitrov
- Introduce new macro ALL_TLS_RECORD_VERSIONS to decouple ALL_AVAILABLE_VERSIONS from the list of valid TLS record versions. It consists of versions allowed in TLSCiphertext.version (TLS 1.2 and prior) and TLSCiphertext.legacy_record_version (TLS 1.3). - TLS 1.3 sets TLSCiphertext.legacy_record_version to 0x0303 for all records generated other than an initial ClientHello, where it MAY also be 0x0301. - TLSPlaintext.legacy_record_version is ignored.

2018-07-09ssl: Improve error handlingIngela Anderton Andin
When doing ssl:controlling_process on a ssl socket that has not performed the TLS/DTLS handshake that call will succeed even though the documentation stated otherwise. However if some other ssl option was incorrect the call would hang. Now {error, closed} will be returned in the latter case, which is logical independent on if it should succeed or not in the former case. The former case will continue to succeed, as it is not dependent of the TLS/DTLS connection being established, and the documentation is altered slightly to not explicitly disallow it. If the TLS/DTLS connection later fails and the socket mode is active, the new controlling process will be notified as expected.
2018-07-02ssl: Add support for stateful loggingPéter Dimitrov
- Introduce stateful logging levels to the ssl application: The SSL option 'log_alert' sets log level to notice/warning if it is set to true/false. Default log level is notice. - Add new SSL option 'log_level' that overrides the value of 'log_alert'. Default value is notice. - 'log_level' debug triggers verbose logging of TLS protocol messages and logging of ignored alerts in DTLS. Change-Id: I28d3f4029a5d504ec612abe4b9ae0b7d9b115197
