init_per_testcase timeout for renegotiation tests would be overridden
by local timeout in test case help function.

Skip some test on really slow solaris machines

Tests in ECC_SUITE did not always use the certs implied by the
name. Variable naming also confused the intent.
ssl_certificate_verify_SUITE did not clean up properly and tests could
fail due to cache problems.

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.

ssl servers can recognize sslv2 client hellos to interop with clients
that support higher version of SSL/TLS but also offers sslv2

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.

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".

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).

We are working on including DTLS support. And we want to include
the contributed tests now before making planned enhancements to the
test suits.

Consolidate code that logs TLS/DTLS version during testing
into ssl_test_lib.

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.

It was not possible to mix ssl 3 and 4 tuple cipher suites in the
ciphers option.
Some ssl_cipher:suite/1 clauses wrongly returned 3-tuples that
should have been 4 tuples

ssl already used crypto:strong_rand_bytes/1 for most operations as
its use cases are mostly cryptographical. Now crypto:strong_rand_bytes/1
will be used everywhere.
However crypto:rand_bytes/1 was used as fallback if
crypto:strong_rand_bytes/1 throws low_entropy, this
will no longer be the case. This is a potential incompatibility.
The fallback was introduced a long time ago for interoperability reasons.
Now days this should not be a problem, and if it is, the security
compromise is not acceptable anyway.

In TLS-1.2 The signature algorithm and the hash function algorithm
used to produce the digest that is used when creating the digital signature
may be negotiated through the signature algorithm extension RFC 5246.
We want to make these algorithm pairs configurable.
In connections using lower versions of TLS these algorithms are
implicit defined and can not be negotiated or configured.
DTLS is updated to not cause dialyzer errors, but needs to get a real
implementation later.

Older SSL/TLS versions have cipher suites
that look like {key_exchange(), cipher(), MAC::hash()}
and the hash function used by the PRF (Pseudo Random function)
is implicit and always the same for that protocol version.
In TLS 1.2 a cipher suite is
{key_exchange(), cipher(), MAC::hash(), PRF::hash()}.
Internally a cipher suite is always a four tuple but
for backwards compatibility older cipher suites
will be presented as a three tuples, however new cipher suites
should be presented as four tuples.

Make sure that options only relevant for one role (client|server) is set
to undefined when the other role is invoked. As there are many options to
ssl, and many are optional, we choose to filter out all undefined options
to avoid overwhelming the user with not relevant information.
This way there is no need for any special handling of the role specific options
which is also nice.

Add a test to ensure that a single 'raw' option can be passed to
ssl:listen correctly.
Note: multiple raw options are (incorrectly) handled by
inet:listen_options. See

Add possibility to downgrade an SSL/TLS connection to a tcp connection,
and give back the socket control to a user process.
Add application setting to be able to change fatal alert shutdown
timeout, also shorten the default timeout. The fatal alert timeout is
the number of milliseconds between sending of a fatal alert and
closing the connection. Waiting a little while improves the
peers chances to properly receiving the alert so it may
shutdown gracefully.

* ferd/deny-client-renegotiation:
Add disable client-initiated renegotiation option
Conflicts:
lib/ssl/doc/src/ssl.xml
lib/ssl/src/ssl.erl
OTP-12815
|
|
Client-initiated renegotiation is more costly for the server than the
client, and this feature can be abused in denial of service attempts.
Although the ssl application already takes counter-measure for these
(via cooldown periods between renegotiations), it can be useful to
disable the feature entirely.
This patch adds the `{client_renegotiation, boolean()}' option to the
server-side of the SSL application (defaulting to `true' to be
compatible with the current behaviour).
The option disables the ability to do any renegotiation at all in the
protocol's state, reusing the existing denial code, but without opening
the code path that sets up a timed message to eventually reopen it up.
