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

2016-06-13ssl: Mitigate load increase when the whole session table is invalidatedIngela Anderton Andin
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.
2016-06-09ssl: ordsets:intersection/2 did not give the expected resultIngela Anderton Andin
Turns out we can not count on the "hashsigns" sent by the client and the supported "hashigns" sets to have required properties of ordsets.

correctly and determines what should happen.
2016-06-09Add ssl:getstat/1 and ssl:getstat/2Loïc Hoguin
These functions call getstat on the underlying TCP socket. The only way to do this before now was to use a hack, either by looking inside the #sslsocket{} record directly, or by not using the SSL listen/accept functions and upgrading from a TCP socket that is kept around for the purpose of calling getstat later on.

2016-05-31Improve SSL diagnosticsAlexey Lebedeff
There are a lot of cases where `ssl` application just returns unhelpful `handshake failure` or `internal error`. This patch tries to provide better diagnostics so operator can debug his SSL misconfiguration without doing hardcore erlang debugging. Here is an example escript that incorrectly uses server certificate as a client one: https://gist.github.com/binarin/35c34c2df7556bf04c8a878682ef3d67 With the patch it is properly reported as an error in "extended key usage".

2016-05-26ssl: Add BEAST mitigation selection optionKenneth Lakin
Some legacy TLS 1.0 software does not tolerate the 1/n-1 content split BEAST mitigation technique. This commit adds a beast_mitigation SSL option (defaulting to one_n_minus_one) to select or disable the BEAST mitigation technique. Valid option values are (one_n_minus_one | zero_n | disabled).
