Motivation:
Users should use PromiseNotifier.cascade(...) methods and so the UnaryPromiseNotifier becomes useless.
Modifications:
- Mark UnaryPromiseNotifier as deprecated
- Replaces usages with PromiseNotifier.cascade(...)
Result:
Cleanup
Motivation:
While OpenSSK is provided support for the "RSASSA-PSS" algorithm this was still not valid from netty. Which was causing issue in validating certificates which was signed using this algorithm.
Modification:
Added "RSASSA-PSS" in LOCAL_SUPPORTED_SIGNATURE_ALGORITHMS.
validation:
Validated and tested with CA and User cert singed with RSASSA-PSS algorithm.
Result:
Fixes#11360

Motivation:
Protocols and Cipher suites constants to prevent typos in protocol and cipher suites names and ease of use.
Modification:
Added Protocols and Cipher suites as constants in their respective classes.
Result:
Fixes#11393
Motivation:
Conscrypt not correctly filters out non support TLS versions which may lead to test failures.
Related to https://github.com/google/conscrypt/issues/1013
Modifications:
- Bump up to latest patch release
- Add workaround
Result:
No more test failures caused by conscrypt
Motivation:
We've seen (very rare) flaky test failures due to timeouts.
They are too rare to analyse properly, but a theory is that on overloaded, small cloud CI instances, it can sometimes take a surprising amount of time to start a thread.
It could be that the event loop thread is getting an unlucky schedule, and takes seconds to start, causing the timeouts to elapse.
Modification:
Increase the initial timeouts in the SSLEngineTest, that could end up waiting for the event loop thread to start.
Also fix a few simple warnings from Intellij.
Result:
Hopefully we will not see these tests be flaky again.
Motivation:
It turned out we didnt run the openssl tests on the CI when we used the non-static version of netty-tcnative.
Modifications:
- Upgrade netty-tcnative to fix segfault when using shared openssl
- Adjust tests to only run session cache tests when openssl supports it
- Fix some more tests to only depend on KeyManager if the underlying openssl version supports it
Result:
Run all openssl test on the CI even when shared library is used
Motivation:
At the moment we don't support session caching on the client side at all when using the native SSL implementation. We should at least allow to enable it.
Modification:
Allow to enable session cache for client side but disable ti by default due a JDK bug atm.
Result:
Be able to cache sessions on the client side when using native SSL implementation .
Motivation:
We didnt correctly filter out TLSv1.3 ciphers when TLSv1.3 is not enabled.
Modifications:
- Filter out ciphers that are not supported due the selected TLS version
- Add unit test
Result:
Fixes https://github.com/netty/netty/issues/10911
Co-authored-by: Bryce Anderson <banderson@twitter.com>
Motivation:
We should expose some methods as protected to make it easier to write custom SslContext implementations.
This will be reused by the code for https://github.com/netty/netty-incubator-codec-quic/issues/97
Modifications:
- Add protected to some static methods which are useful for sub-classes
- Remove some unused methods
- Move *Wrapper classes to util package and make these public
Result:
Easier to write custom SslContext implementations
Motivation:
HTTP is a plaintext protocol which means that someone may be able
to eavesdrop the data. To prevent this, HTTPS should be used whenever
possible. However, maintaining using https:// in all URLs may be
difficult. The nohttp tool can help here. The tool scans all the files
in a repository and reports where http:// is used.
Modifications:
- Added nohttp (via checkstyle) into the build process.
- Suppressed findings for the websites
that don't support HTTPS or that are not reachable
Result:
- Prevent using HTTP in the future.
- Encourage users to use HTTPS when they follow the links they found in
the code.
Motivation:
We need to take the Provider into account as well when trying to detect if TLSv1.3 is used by default / supported
Modifications:
- Change utility method to respect provider as well
- Change testcode
Result:
Less error-prone tests
Motivation:
Some JDKs dissallow the usage of keysizes < 2048, so we should not use such small keysizes in tests.
This showed up on fedora 32:
```
Caused by: java.security.cert.CertPathValidatorException: Algorithm constraints check failed on keysize limits. RSA 1024bit key used with certificate: CN=tlsclient. Usage was tls client
at sun.security.util.DisabledAlgorithmConstraints$KeySizeConstraint.permits(DisabledAlgorithmConstraints.java:817)
at sun.security.util.DisabledAlgorithmConstraints$Constraints.permits(DisabledAlgorithmConstraints.java:419)
at sun.security.util.DisabledAlgorithmConstraints.permits(DisabledAlgorithmConstraints.java:167)

at sun.security.provider.certpath.PKIXMasterCertPathValidator.validate(PKIXMasterCertPathValidator.java:125)
... 23 more
```
Modifications:
Replace hardcoded keys / certs with SelfSignedCertificate
Result:
No test-failures related to small key sizes anymore.
Motivation:
This reverts commit 825916c7f0 as it turns out it introduced a big performance regression.
Modifications:
Revert 825916c7f0
Result:
Performance of TLS is back to normal
Motiviation:
When TLSv1.3 was introduced almost 2 years ago, it was decided to disable it by default, even when it's supported by the underlying TLS implementation.
TLSv13 is pretty stable now in Java (out of the box in Java 11, OpenJSSE for Java 8, BoringSSL and OpenSSL) and may be enabled by default.
Modifications:
Ensure TLSv13 is enabled by default when the underyling JDK SSLEngine implementation enables it as well
Result:
TLSv1.3 is now enabled by default, so users don't have to explicitly enable it.
Co-authored-by: Stephane Landelle <slandelle@gatling.io>
Motivation:
TLSv1.3 is not strictly limited to Java11+ anymore as different vendors backported TLSv1.3 to Java8 as well. We should ensure we make the detection of if TLSv1.3 is supported not depend on the Java version that is used.
Modifications:
- Add SslProvider.isTlsv13Supported(...) and use it in tests to detect if we should run tests against TLSv1.3 as well
- Adjust testcase to work on latest JDK 8 release as well
Result:
Correct detection of TLSv1.3 support even if Java version < 11.
Motivation:
At the moment we don't support session caching for client side when using native SSLEngine implementation and our implementation of SSLSessionContext is incomplete.
Modification:
- Consume netty-tcnative changes to be able to cache session in an external cache
- Add and adjust unit tests to test session caching
- Add an in memory session cache that is hooked into native SSLEngine
Result:
Support session caching on the client and server side
Motivation:
BoringSSL behaves differently then OpenSSL and not include any TLS1.3 ciphers in the returned array when calling SSL_get_ciphers(...). This is due the fact that it also not allow to explicit configure which are supported and which not for TLS1.3. To mimic the behaviour expected by the SSLEngine API we should workaround this.
Modifications:
- Add a unit test that verifies enabled protocols / ciphers
- Add special handling for BoringSSL and tls1.3
Result:
Make behaviour consistent
Motivation:
Due a bug in our test we may dropped data on the floor which are generated during handshaking (or slightly after). This could lead to corrupt state in the engine itself and so fail tests. This is especially true for TLS1.3 which generates the sessions on the server after the "actual handshake" is done.
Modifications:
Contine with wrap / unwrap until all data was consumed
Result:
Correctly feed all data to the engine during testing
Motivation:
SslHandler currently throws a general SSLException if a wrap attempt
fails due to the SSLEngine being closed. If writes are queued the
failure rational typically requires more investigation to track down the
original failure from a previous event. We may have more informative
rational for the failure and so we should use it.
Modifications:
- SslHandler#wrap to use failure information from the handshake or prior
transport closure if available
Result:
More informative exceptions from SslHandler#wrap if the SSLEngine has
been previously closed.
Motivation:
OpenSslSession.getLocalCertificates() and getLocalPrincipal() must return null on client side if mTLS is not used as stated in the API documentation. At the moment this is not always the case
Modifications:
- Ensure we only return non-null if mTLS is used
- Add unit tests
Result:
Follow SSLSession API contract
Motivation:
We are far behind with the version of Conscrypt we are using during testing. We should ensure we use the latest.
Modifications:
- Update conscrypt dependency
- Ensure we use conscrypt provider in tests
- Add workarounds for conscrypt bugs in testsuite
Result:
Use latest Conscrypt release
Motivation:
We need to make some slightly changes to be able to build on Java15 as some previous deprecated methods now throw UnsupportedOperationException
Modifications:
- Add code to handle UnsupportedOperationException
- Revert previous applied workaround for bug that was fixed in Java15
- Add maven profile
Result:
Be able to build with latest Java15 EA release
Motivation:
ALPN support was backported to java 8 lately. Ensure we support it if the user uses the latest java 8 release
Modifications:
- Update logic to be able to detect if ALPN is supported out of the box when using Java8
- Update jetty alpn version
Result:
Be able to use ALPN out of the box when using java 8u251
Motivation:
JDK 14 was released and need some special settings to be able to build with. Also there seems to be one regression that we need to workaround for now.
Modifications:
- Add maven profile for JDK 14
- Update blockhound version to be able to work on JDK 14
- Add workaround for possible JDK 14 regression
Result:
Be able to build on JDK 14
Motivation:
We did not correctly handle taskoffloading when using BoringSSL / OpenSSL. This could lead to the situation that we did not write the SSL alert out for the remote peer before closing the connection.
Modifications:
- Correctly handle exceptions when we resume processing on the EventLoop after the task was offloadded
- Ensure we call SSL.doHandshake(...) to flush the alert out to the outboundbuffer when an handshake exception was detected
- Correctly signal back the need to call WRAP again when a handshake exception is pending. This will ensure we flush out the alert in all cases.
Result:
No more failures when task offloading is used.
Motivation
Debugging SSL/TLS connections through wireshark is a pain -- if the cipher used involves Diffie-Hellman then it is essentially impossible unless you can have the client dump out the master key [1]
This is a work-in-progress change (tests & comments to come!) that introduces a new handler you can set on the SslContext to receive the master key & session id. I'm hoping to get feedback if a change in this vein would be welcomed.
An implementation that conforms to Wireshark's NSS key log[2] file is also included.
Depending on feedback on the PR going forward I am planning to "clean it up" by adding documentation, example server & tests. Implementation will need to be finished as well for retrieving the master key from the OpenSSL context.

Modification
- Added SslMasterKeyHandler
- An implementation of the handler that conforms to Wireshark's key log format is included.
Result:
Be able to debug SSL / TLS connections more easily.

Motivation:
asList should only be used if there are multiple elements.
Modification:
Call to asList with only one argument could be replaced with singletonList
Result:
Cleaner code and a bit of memory savings
Motivation:
As brought up in https://github.com/netty/netty/issues/8998, JKS can be substantially faster than pkcs12, JDK's new default. Without an option to set the KeyStore type you must change the configuration of the entire JVM which is impractical.
Modification:
- Allow to specify KeyStore type
- Add test case
Result:
Fixes https://github.com/netty/netty/issues/8998.
Motivation:
We do not need to call SSL.setHostNameValidation(...) as it should be done as part of the TrustManager implementation. This is consistent with the JDK implementation of SSLEngine.
Modifications:
Remove call to SSL.setHostNameValidation(...)
Result:
More consistent behaviour between our SSLEngine implementation and the one that comes with the JDK.
Motivation:
We had a bug which could case ExtendedSSLSession.getPeerSupportedSignatureAlgorithms() return an empty array when using BoringSSL. This testcase verifies we correctly return algorithms after the fix in https://github.com/netty/netty-tcnative/pull/449.
Modifications:
Add testcase to verify behaviour.
Result:
Ensure we correctly retuen the algorithms.
Motivation:
The SSLSession that is returned by SSLEngine.getHandshakeSession() must be able to provide the local certificates when the TrustManager is invoked on the server-side.
Modifications:
- Correctly return the local certificates
- Add unit test
Result:
Be able to obtain local certificates from handshake SSLSession during verification on the server side.
Motivation:
fa6a8cb09c introduced correct dispatching of delegated tasks for SSLEngine but did not correctly handle some cases for resuming wrap / unwrap after the task was executed. This could lead to stales, which showed up during tests when running with Java11 and BoringSSL.
Modifications:
- Correctly resume wrap / unwrap in all cases.
- Fix timeout value which was changed in previous commit by mistake.
Result:
No more stales after task execution.
Motivation:
We use outdated EA releases when building and testing with JDK 12 and 13.
Modifications:
- Update versions.
- Add workaround for possible JDK12+ bug.
Result:
Use latest releases
Motivation:
The SSLEngine does provide a way to signal to the caller that it may need to execute a blocking / long-running task which then can be offloaded to an Executor to ensure the I/O thread is not blocked. Currently how we handle this in SslHandler is not really optimal as while we offload to the Executor we still block the I/O Thread.
Modifications:
- Correctly support offloading the task to the Executor while suspending processing of SSL in the I/O Thread
- Add new methods to SslContext to specify the Executor when creating a SslHandler
- Remove @deprecated annotations from SslHandler constructor that takes an Executor
- Adjust tests to also run with the Executor to ensure all works as expected.
Result:
Be able to offload long running tasks to an Executor when using SslHandler. Partly fixes https://github.com/netty/netty/issues/7862 and https://github.com/netty/netty/issues/7020.
Motivation:
During some other work I noticed we do not have any tests to ensure we correctly use SSLSessionBindingEvent. We should add some testing.
Modifications:
- Added unit test to verify we correctly implement it.
- Ignore the test when using Conscrypt as it not correctly implements it.
Result:
More tests for custom SSL impl.
Motivation:
In windows if the project is in a path that contains whitespace,
resources cannot be accessed and tests fail.
Modifications:
Adds ResourcesUtil.java in netty-common. Tests use ResourcesUtil.java to access a resource.
Result:
Being able to build netty in a path containing whitespace
Motivation:
The SSLSession.getLocalCertificates() / getLocalPrincipial() methods did not correctly return the local configured certificate / principal if a KeyManagerFactory was used when configure the SslContext.
Modifications:
- Correctly update the local certificates / principial when the key material is selected.
- Add test case that verifies the SSLSession after the handshake to ensure we correctly return all values.
Result:
SSLSession returns correct values also when KeyManagerFactory is used with the OpenSSL provider.
Motivation:
We did not correctly convert between openssl / boringssl and java ciphers when using TLV1.3 which had different effects when either using openssl or boringssl.
- When using openssl and TLSv1.3 we always returned SSL_NULL_WITH_NULL_NULL as cipher name
- When using boringssl with TLSv1.3 we always returned an incorrect constructed cipher name which does not match what is defined by Java.
Modifications:
- Add correct mappings in CipherSuiteConverter for both openssl and boringssl
- Add unit tests for CipherSuiteConvert
- Add unit in SSLEngine which checks that we do not return SSL_NULL_WITH_NULL_NULL ever and that server and client returns the same cipher name.
Result:
Fixes https://github.com/netty/netty/issues/8477.
Motivation:
We should call wrapEngine(...) in our SSLEngineTest to correctly detect all errors in case of the OpenSSLEngine.
Modifications:
Add missing wrapEngine(...) calls.
Result:
More correct tests
Motivation:
https://github.com/netty/netty/issues/8442 reported that we fail to build a SslContext when an invalid cipher is used with netty-tcnative-boringssl-static, while it worked before. This test verifies that this is now consistent with all other SSLEngine implementations.
Modifications:
Add test-case to verify consistent behaviour
Result:
More tests to assert consistent behaviour across SSLEngine implementations
Motivation:
0ddc62cec0 added support for TLSv1.3 when using openssl 1.1.1. Now that BoringSSL chromium-stable branch supports it as well we can also support it with netty-tcnative-boringssl-static.
During this some unit tests failed with BoringSSL which was caused by not correctly handling flush() while the handshake is still in progress.
Modification:
- Upgrade netty-tcnative version which also supports TLSv1.3 when using BoringSSL
- Correctly handle flush() when done while the handshake is still in progress in all cases.
Result:
Easier for people to enable TLSv1.3 when using native SSL impl.
Ensure flush() while handshake is in progress will always be honored.
Motivation:
We had put some workaround in our tests due a bug in the Java11 implementation of TLSv1.3. This was now fixes as part of 11.0.1.
See https://bugs.openjdk.java.net/browse/JDK-8211067.
Modifications:
Remove workaround in SSL tests.
Result:
Run all tests with supported TLS version.
Motivation:
At the moment it's only possible to use TLSv1.3 with netty-tcnative if Java 11 is used. It should be possible to do so even with Java 8, 9 and 10.
Modification:
Add a workaround to be able to use TLSv1.3 also when using Java version prior to Java 11 and the default X509ExtendedTrustManager is used.
Result:
Be able to use TLSv1.3 also with past versions of Java.
Motivation:
TLSv1.3 support is included in java11 and is also supported by OpenSSL 1.1.1, so we should support when possible.
Modifications:
- Add support for TLSv1.3 using either the JDK implementation or the native implementation provided by netty-tcnative when compiled against openssl 1.1.1
- Adjust unit tests for semantics provided by TLSv1.3
- Correctly handle custom Provider implementations that not support TLSv1.3
Result:
Be able to use TLSv1.3 with netty.
Motivation:
a208f6dc7c added a testcase which uses hostname validation which may not be supported by OpenSSL depending on the version that is used. We should check first before we try to use it.
Modifications:
Add assumeTrue(...) check to ensure hostname validation is supported before trying to run the test.
Result:
No more test-failures on OpenSSL versions < 1.0.2.
