<div dir="ltr"><div dir="ltr"><div dir="ltr"><div>Xuelei,</div><div><br></div><div dir="ltr">I have a sample socket client for the device TLS issue but its not very helpful as any socket client created on top of JDK will do, the last problem was apparent only when talking to a specific hardware device which refused to negotiate TLS session (I've seen several odd TLS implementations that were intolerant to Java changes in various ways over the years and compatibility could always be assured through config changes, this time around less so).</div><div dir="ltr"><br></div><div dir="ltr">Some of the hardware TLS stacks can range from small oddities to being completely broken by small changes as they can contain outdated and poorly implemented TLS stacks that are very sensitive so even a small change can break them and thats why its always important to have levers provided to control almost every aspect of the handshake.<br><div><br></div><div>I have a sample in my gist (<a href="https://gist.github.com/amir-khassaia/04347ca88526f4b958b3326968a905c0">https://gist.github.com/amir-khassaia/04347ca88526f4b958b3326968a905c0</a>), apologies its in Kotlin. When ran with java 8, 9, 10 there were no issues. With java 11 this worked on most devices but I've had a device at a remote location that was not in my control that I've had to diagnose the handshake failure on using java 11 it was intolerant to TLS 1.2 client hello from Java 11 but fine with TLS 1.1 as the new extensions are not present. It would be fine with TLS 1.2 client hello from Java 10 and earlier as I mentioned.</div><div><br></div><div>Javax.net.debug output</div><div>-------------------------------</div>javax.net.ssl|DEBUG|01|main|2019-01-08 13:40:14.395 AEDT|SSLCipher.java:437|jdk.tls.keyLimits: entry = AES/GCM/NoPadding KeyUpdate 2^37.

<p>Hi Amir,</p>
<p>Normally, the extension should have no impact if it cannot be
recognized by the server. It's good to be able to disable
extensions if not needed. I need to evaluate the priority of it
although. Did you have a simple test code that I can reproduce
the issue?</p>
<p>Thanks,</p>
<p>Xuelei<br>

The fact is, some of the extensions sent by JSSE are changes
to TLS 1.2 to support TLS 1.3, this however affects some
clients adversely in practice and usually JDK provides
properties to turn new enhancements off and work around such
behaviour, for the extensions I mentioned this is not provided
and hence they are always sent for client sockets unless
TLSv1.2 is not in use. </div>
<div><br>
</div>
<div>The impact to us is that upgrading to JDK11 means for some
endpoints or devices that are not 100% compliant to the spec
the security is reduced as we have to now work around to drop
connections to these to TLSv1.1 or TLS1.0 or not to move to
Java 11 at all.</div>
<div>
<pre style="white-space:pre-wrap"><font face="Arial, Helvetica, sans-serif"><span style="white-space:normal">My request is simply to have all of the new extensions configurable on individual basis so that they can be turned off if needed for compatibility just like most other security enhancements that were delivered in the past.</span></font></pre>
It appears some of the issues can come from <br>
<br>
- inclusion of RSASSA-PSS alg in TLS 1.2 handshakes but these
can disabled at least<br>
<br>
-signature_algorithms_cert and supported_versions extensions
which seem to be hardcoded for TLS 1.2 (I was not able to
conclusively identify which of these caused my troubles)<br>
<br>
<a href="https://tools.ietf.org/html/rfc8446#section-1.3" target="_blank">https://tools.ietf.org/html/rfc8446#section-1.3</a> does
say that TLS 1.2 clients are affected but in an optional
manner.Just today I've encountered another Java 11 interop
issue with TLS but this time with a physical device which can
have a long shelf life yet running a simple client socket
handshake abruptly terminates the connection upon client hello
(no server_hello at all), and downgrading the JRE below 11
works fine. I'm including a trace for that as well:
