Motivation:
We want to make the experience as smooth as possible for our users when using Java9+ and so should ensure we do not produce any 'Illegal reflective access' errors when using netty.
Modifications:
Add jvmArgs when running our tests that will deny reflective access and so will fail the build at the end due not be able to load some classes.
Result:
Ensure we do not produce any illegal refelctive access errors when using java9+
Motivation:
SSLEngine API has a notion of tasks that may be expensive and offload these to another thread. We did not support this when using our native implementation but can now for various operations during the handshake.
Modifications:
- Support offloading tasks during the handshake when using our native SSLEngine implementation
- Correctly handle the case when NEED_TASK is returned and nothing was consumed / produced yet
Result:
Be able to offload long running tasks from the EventLoop when using SslHandler with our native SSLEngine.
Motivation:
Netty is very widely used which can lead to a lot of pain when we break API / ABI. We should make use japicmp-maven-plugin during the build to verify we do not introduce breakage by mistake.
Modifications:
- Add japicmp-maven-plugin to the build process
- Fix a method signature change in HttpProxyHandler that was flagged as a possible problem.
Result:
Ensure no API/ABI breakage accour between releases.
Motivation:
We need to update to a new checkstyle plugin to allow the usage of lambdas.
Modifications:
- Update to new plugin version.
- Fix checkstyle problems.
Result:
Be able to use checkstyle plugin which supports new Java syntax.
Motivation:
Since the updating to OpenJDK 11.0.2 the OSGI testsuite fails. We should dissable it until there is a version of the used plugins that works with this OpenJDK version.
Modifications:
Skip osgi testsuite when using JDK11.
Result:
Build pass again with JDK11.
Motivation:
There are the first EA bulds for OpenJDK 13. We should support to build with it and run builds on the CI.
Modifications:
- Add profile for JDK 13
- Add docker config to run with JDK 13.
Result:
Building and testing with OpenJDK 13 is possible.
Motivation:
We should use the latest OpenJDK 12 release when running tests against Java12.
Modifications:
- Update to OpenJDK 12 ea22.
- Update pax exam version
- skip OSGI testsuite on Java12 as it does not work ea22 yet.
Result:
Use latest OpenJDK 12 version when running on the CI.
Motivation:
Update to netty-tcnative 2.0.20.Final which fixed a bug related to retrieving the remote signature algorithms when using BoringSSL.
Modifications:
Update netty-tcnative
Result:
Be able to correctly detect the remote signature algorithms when using BoringSSL.
Motivation:
We did not override all methods in OpenSslX509Certificate and delegate to the internal 509Certificate.
Modifications:
Add missing overrides.
Result:
More correct implementation
Motivation:
We should provide an easy way to run our testsuite against netty-tcnative-boringssl-static
Modifications:
- Add boringssl profile which can be used to enable usage of netty-tcnative-boringssl-static
- Make use of the profile in docker-compose
Result:
Cleaner and easier way of running testsuite against netty-tcnative-boringssl-static
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:
Commons-compress < 2.0.18 has a security flaw so we should upgrade (even if we only use it in tests anyway).
Modifications:
Update to 2.0.18
Result:
Use latest version.
Motivation:
We need to update jetty-alpn-agent to be able to run tests with OpenJDK 8u191
Modifications:
Update to 2.0.8
Result:
Be able to run tests with latest JDK 8 release.
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:
Before when on server-side we just called the X509KeyManager methods when handshake() was called the first time which is not quite correct as we may not have received the full SSL hello / handshake and so could not extra for example the SNI hostname that was requested.
OpenSSL exposes the SSL_CTX_set_cert_cb function which allows to set a callback which is executed at the correct moment, so we should use it. This also allows us to support more methods of ExtendedSSLSession easily.
Modifications:
- Make use of new methods exposed by netty-tcnative since https://github.com/netty/netty-tcnative/pull/388 to ensure we select the key material at the correct time.
- Implement more methods of ExtendedOpenSslSession
- Add unit tests to ensure we are able to retrieve various things on server-side in the X509KeyManager and so verify it is called at the correct time.
- Simplify code by using new netty-tcnative methods.
Result:
More correct implementation for server-side usage and more complete implemented of ExtendedSSLSession.
Motivation:
First EA releases of Java12 are out we should be able to compile with these and run tests.
Modifications:
Add maven profile for java12.
Result:
Be able to use Java12
Motivation:
Conscrypt 1.3.0 was just released and adds support for TLSv1.3
Modifications:
Update to 1.3.0
Result:
Use latest conscrypt during build / test.
Motivation:
When an ExtendedSSLSession is used its possible to do more strict checking of the keys during handshake. We should do this whenever possible.
Modification:
- Return an ExtendedSSLSession when using client-mode and Java7+
- Add unit test
- Simplify unit tests
Result:
More consistent behaviour.
Motivation:
We should use the latest netty-tcnative release which contains a fix to correctly support DH based ciphers when using openssl 1.1.x
Modifications:
Update to latest netty-tcnative which has the fix.
Result:
Correctly support DH ciphers in all cases. Fixes https://github.com/netty/netty/issues/8165.
* Allow to use native transports when sun.misc.Unsafe is not present on the system
Motivation:
We should be able to use the native transports (epoll / kqueue) even when sun.misc.Unsafe is not present on the system. This is especially important as Java11 will be released soon and does not allow access to it by default.
Modifications:
- Correctly disable usage of sun.misc.Unsafe when -PnoUnsafe is used while running the build
- Correctly increment metric when UnpooledDirectByteBuf is allocated. This was uncovered once -PnoUnsafe usage was fixed.
- Implement fallbacks in all our native transport code for when sun.misc.Unsafe is not present.
Result:
Fixes https://github.com/netty/netty/issues/8229.
Motivation:
OpenSSL itself has an abstraction which allows you to customize some things. For example it is possible to load the PrivateKey from the engine. We should support this.
Modifications:
Add two new static methods to OpenSslX509KeyManagerFactory which allow to create an OpenSslX509KeyManagerFactory that loads its PrivateKey via the OpenSSL Engine directly.
Result:
More flexible usage of OpenSSL possible
Motivation:
There is a JDK bug which will return IP_TOS as supported option for ServerSocketChannel even if its not supported afterwards and cause an AssertionError.
See http://mail.openjdk.java.net/pipermail/nio-dev/2018-August/005365.html.
Modifications:
Add a workaround for the JDK bug.
Result:
ServerSocketChannel.config().getOptions() will not throw anymore and work as expected.
* Support the usage of SocketOption when nio is used and the java version >= 7.
Motivation:
The JDK uses SocketOption since java7 to support configuration options on the underyling Channel. We should allow to create a ChannelOption from a given SocketOption if nio is used. This also allows us to expose the same featureset in terms of configuration as the java nio implementation does without any extra effort.
Modifications:
- Add NioChannelOption which allows to wrap an existing SocketOption which then can be applied to the nio transport.
- Add test-cases
Result:
Support the same configuration options as the JDK. Also fixes https://github.com/netty/netty/issues/8072.
Motivation:
It's easy to break the support for shading native libs as shown in https://github.com/netty/netty/issues/8090. We should have some testing to ensure all works as expected.
Modification:
Add new testsuite which verifies that shading our native transports work as expected.
Result:
Include test to verify shading of native code.
Motivation:
A new version of tcnative was released that allows to use features depending on the runtime version of openssl, which makes it possible to use KeyManagerFactory and hostname verification on newer versions of centos/fedora/rhel and debian/ubuntu without the need to compile again.
Modifications:
Update to 2.0.12.Final
Result:
Use latest version of netty-tcnative to support more features.
Motiviation:
During profiling it showed that a lot of time during the handshake is spent by parsing the key / chain over and over again. We should cache these parsed structures if possible to reduce the overhead during handshake.
Modification:
- Use new APIs provided by https://github.com/netty/netty-tcnative/pull/360.
- Introduce OpensslStaticX509KeyManagerFactory which allows to wrap another KeyManagerFactory and caches the key material provided by it.
Result:
In benchmarks handshake times have improved by 30 %.
Motivation:
netty-tcnative 2.0.9 did not contain all native code for boringssl due a release mistake.
Modifications:
Update to 2.0.10
Result:
Use latest netty-tcnative release.
Motivation:
netty-tcnative 2.0.9.Final was released which fixes a memory leak that can happen if client auth is used via client side.
Modifications:
Update to latest netty-tcnative.
Result:
No more memory leak.
Motivation:
When using conscrypt some NPEs were logged, these were fixed in the latest release.
Modifications:
Update to conscrypt 1.1.3.
Result:
Fixes https://github.com/netty/netty/issues/7988.
