* ingela/ssl/dtls-alert-handling/OTP-14078:
dtls: Customize alert handling for DTLS over UDP
|
|
Test that DTLS handles "high" level packet types as http-packet types.
Low level packet type as {packet, 2} we will consider later if they
should be relevant to support or not.
|
|
Also run this suit on all TLS versions
|
|
|
|
Problems with failure of ssl_certificate_verify_SUITE when enabling DTLS-1
tests in ssl_basic_SUITE was a combination of the bug fixed by the
previous commit and missing clean up code for dtls_protocol_versions
application environment variable

* ingela/ssl/timeout-cuddle:
ssl: Longer timeouts for test cases that do many handshakes
|
|
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.

* ingela/dtls/cuddle:
ssl: Handle OpenSSL output correctly
|
|
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.
|
|
|
|
Adjust to handle output from OpenSSL in a more general way, so that
"unknown option" should be caught for all cases and the test case
skipped if that is the case and other data form OpenSSL should be
ignored.
|
|
This code was not used and we already have mixed chains ECDH_RSA tests
|
|
We are not testing OpenSSL. We want to test interoperability with OpenSSL
|
|
|
|
|
|
If net_adm:localhost() returns a FQDN we want to use it otherwise
we want to use localhost.

The -ssl2 option to s_client appears to be broken on this release.
This is a legacy option anyway that is still tested on other old
version of OpenSSL so skip this.

The commit 8b10920 (OTP 19.3.1) fixed the non-delivery of final TLS
record in {active, once}, but this causes the ssl_closed message to be
lost when the TCP connection closes before ssl:close/1. The patch
restores the behavior of OTP 18.
This is the second part to fix https://bugs.erlang.org/browse/ERL-420
|
|
Test should check that we get the expected key exchange algorithm
for the provided server cert. We do not want to test OpenSSL s_server.
Do not try to test cipher suites against OpenSSL that it does not
support.

When the server_name_indication is sent automatize the
clients check of that the hostname is present in the
servers certificate. Currently server_name_indication shall
be on the dns_id format. If server_name_indication is disabled
it is up to the user to do its own check in the verify_fun.

|
With the new help functions for creating test data we can simplify the
code. And sometimes corrections have been made so that the test actually
perform the test intended.
|
|
The certificate chain handling had become quite entangled and
was not correct.
|
|
* ingela/ssl/make-cert-test-data/OTP-14294:
ssl, public_key: Add functionality for generating X509 cert test data
|
|
For now this functionality is located in ssl. And existing
public_key function is extended. However some of the functionality may
be moved to public_key in a later stage.
|
|
Add session_id and remove undocumented ssl:session_info/1
Add client_random, server_random and master_secret, they will not be included
in ssl:connection_information/1 as they may affect the connections security if
used recklessly.

We want to avoid failing test cases but still be able to merge
DTLS progress for 19.3
|
|
|
|
The new_options_in_accept test is not working yet, however DTLS is still
work in progress and we want to make a progress merge to avoid merge conflicts
with other progress of the ssl application.
|
|
We need to figure out a good way of knowing if the OpenSSL-"DTLS server" is up.
Some of the code in this commit is attempting this, but it is not really working
yet, and hence only tests where OpenSSL is client are enabled.
|

Change retransmissions timers to use gen_statem state timeouts. We do
not need a retransmission timer in the state connection as data traffic in
DTLS over UDP is not retransmitted. If the last flight before
transitioning into connection is lost, it will be resent when the peer
resends its last flight. This will also make hibernation testing more
straight forward.
We need more adjustments later to handle a reliable DTLS transport
such as SCTP.
