2016-09-05ssl: Refactor code so that tls and dtls can share more codeIngela Anderton Andin
We want to share more alert and application data handling code. Some of the application data handling code, packet handling, will not be relevant for dtls, but this code can be excluded from dtls by options checking.
2016-09-05ssl, dtls: Disable V2 compatibility clause from ↵Ingela Anderton Andin
ssl_handshake:update_handshake_history This proably a much bigger problem for DTLS than TLS, but should be disabled for both unless explicitly configured for TLS.
2016-09-05ssl: Make sure common code for TLS and DTLS uses the TLS VersionIngela Anderton Andin
When protocol version is proagated from the DTLS connection processes state into general ssl functions it must be converted to the corresponding TLS version.

Conflicts: lib/ssl/src/ssl_handshake.erl
2016-09-05dtls: Add reinit_handshake_data/1 to dtlsIngela Anderton Andin
The callback is invoke before entering state 'connection'. It allows a connection module to remove data from the connection state that is no longer needed (e.g. handshake history).

2016-07-21Improve version selectionRaimo Niskanen
Use the list of versions that the server allows and among those choose the highest version that is not higher than the client's version. Note that this chosen version might be lower than the client's version, but is used to improve interoperability. Patch suggested by Dimitry Borisov refering to RFC 5246 appendix E.1.

2016-06-13dtls: rework handshake flight encodeingAndreas Schultz
The MSS might change between sending the a flight and possible resend. We therefore have to be able to fragment the records differently for resent. Encoding and fragmenting of handshake record therefor needs to be done independently. With this change the handshake is encoded to it's full length first, then queued to a flight. The fragmentation is handled during assembly of the flights datagram. Conflicts: lib/ssl/src/dtls_connection.erl

2016-06-13ssl: introduce the notion of flights for dtls and tlsAndreas Schultz
The flight concept was introduced by DTLS (RFC 4347) to optimize the packing of DTLS records into UDP packets. This change implments the flight concept in the the generic SSL connection logic and add the queue logic to the TLS and DTLS stack. The DTLS required resend handling is not implemented yet. While the flight handling is only required for DTSL, it turns out that the same mechanism can be usefull to TCP based TLS as well. With the current scheme each TLS record will be mapped into a separate TCP frame. This causes more TCP frames to be generate that necessary. On fast network this will have no impact, but reducing the number of frames and thereby the number of round trips can result in significant speedups on slow and unreliable networks. Conflicts: lib/ssl/src/tls_connection.erl
2016-06-13ssl: move available_signature_algs to ssl_handshakeAndreas Schultz
available_signature_algs is also needed for DTLS, move it into a shared place and export it. Conflicts: lib/ssl/src/tls_handshake.erl

2016-06-09ssl: Use cipher suite's PRF in prf/5Kenneth Lakin
Use the negotiated cipher suite's PRF algorithm in calls to ssl:prf/5, rather than a hard-coded one. For TLS 1.0 the PRF algorithm was hard-coded to MD5/SHA1. This was correct 100% of the time. For TLS 1.1 and 1.2 the PRF algorithm was hard-coded to SHA256. This was correct only some of the time for TLS 1.2 and none of the time for TLS 1.1. Because the TLS handshake code calls tls_v1:prf/5 through another path, the handshaking process used the negotiated PRF and did not encounter this bug. A new test (prf) has been added to ssl_basic_SUITE to guard against future breakage.
2016-06-09ssl:recv timeout() can be 0Joe DeVivo
gen_tcp:recv allows this, and if you're doing something like Transport:recv(Socket, 0, 0), TCP will work and SSL will exit with function_clause There were other cases of this throughout the module. This PR cleans them all up.
