Cipher test case also needed updating to handle streams correctly
We should not rizzo test chacha20_poly1305
Conflicts:
lib/ssl/test/ssl_basic_SUITE.erl

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.

When internaly using active N, bugs in shutdown implementation where reveled.

Make next_record an internal help function to next_event and avoid
duplicate calls to tls_socket:setopts for setting the active option.

other purposes than handshaking
|
|
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.

Before only some PSK suites would be correctly negotiated and most PSK
ciphers suites would fail the connection.
PSK cipher suites are anonymous in the sense that they do not use
certificates except for rsa_psk.
|
|
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.
|
|
The conversion code for different representations of cipher suites
is long an repetitive. We want to hide it in a module that does not
have other functions that we like to look at.

Transport accepted sockets that are in the error state, was not closed
properly.

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.

Add new API function for converting cipher suite maps
to their textual representation.

The interoperability option to fallback to insecure renegotiation
now has to be explicitly turned on.

Preferably customized cipher suites will be based on the default value.
But all may be used as base and hence it will be good to
handle anonymous suites separately as they are intended for testing purposes.

Otherwhise test can be wrongly initialized and will fail as they try to run

This is an addition to b3ca5727169deaa38917edca8288dcaff9a36800 that accidently

From RFC 6347:
4.1.2.7. Handling Invalid Records
Unlike TLS, DTLS is resilient in the face of invalid records (e.g.,
invalid formatting, length, MAC, etc.). In general, invalid
records SHOULD be silently discarded, thus preserving the
association; however, an error MAY be logged for diagnostic
purposes. Implementations which choose to generate an alert
instead, MUST generate fatal level alerts to avoid attacks where
the attacker repeatedly probes the implementation to see how it
responds to various types of error. Note that if DTLS is run over
UDP, then any implementation which does this will be extremely
susceptible to denial-of-service (DoS) attacks because UDP forgery
is so easy. Thus, this practice is NOT RECOMMENDED for such
transports.

This is mainly fixing the test suites so that they test the intended cipher
suites, issue reported in ERL-460.
Also ssl_cipher:anonymous_suites was corrected for DTLS.
