From 7aefc2781e4be9f223dccfeb7f6eb502713fab0c Mon Sep 17 00:00:00 2001 From: Ingela Anderton Andin Date: Thu, 4 Oct 2018 08:14:37 +0200 Subject: ssl: ERL-738 - Correct alert handling with new TLS sender process 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. --- lib/ssl/test/ssl_alpn_handshake_SUITE.erl | 23 ++++++------ lib/ssl/test/ssl_basic_SUITE.erl | 42 ++++++++++----------- lib/ssl/test/ssl_certificate_verify_SUITE.erl | 54 ++++----------------------- lib/ssl/test/ssl_test_lib.erl | 38 ++++++++++++++++++- 4 files changed, 78 insertions(+), 79 deletions(-) (limited to 'lib/ssl/test') diff --git a/lib/ssl/test/ssl_alpn_handshake_SUITE.erl b/lib/ssl/test/ssl_alpn_handshake_SUITE.erl index 27062d4801..04c4b257d9 100644 --- a/lib/ssl/test/ssl_alpn_handshake_SUITE.erl +++ b/lib/ssl/test/ssl_alpn_handshake_SUITE.erl @@ -155,7 +155,7 @@ empty_client(Config) when is_list(Config) -> run_failing_handshake(Config, [{alpn_advertised_protocols, []}], [{alpn_preferred_protocols, [<<"spdy/2">>, <<"spdy/3">>, <<"http/2">>]}], -
