This commit updates the default ciphers and TLS protocols that are used when the runtime JDK supports them. New cipher support has been introduced in JDK 11 and 12 along with performance fixes for AES GCM. The ciphers are ordered with PFS ciphers being most preferred, then AEAD ciphers, and finally those with mainstream hardware support. When available stronger encryption is preferred for a given cipher. This is a backport of #41385 and #41808. There are known JDK bugs with TLSv1.3 that have been fixed in various versions. These are: 1. The JDK's bundled HttpsServer will endless loop under JDK11 and JDK 12.0 (Fixed in 12.0.1) based on the way the Apache HttpClient performs a close (half close). 2. In all versions of JDK 11 and 12, the HttpsServer will endless loop when certificates are not trusted or another handshake error occurs. An email has been sent to the openjdk security-dev list and #38646 is open to track this. 3. In JDK 11.0.2 and prior there is a race condition with session resumption that leads to handshake errors when multiple concurrent handshakes are going on between the same client and server. This bug does not appear when client authentication is in use. This is JDK-8213202, which was fixed in 11.0.3 and 12.0. 4. In JDK 11.0.2 and prior there is a bug where resumed TLS sessions do not retain peer certificate information. This is JDK-8212885. The way these issues are addressed is that the current java version is checked and used to determine the supported protocols for tests that provoke these issues. |
