Motivation:
https://github.com/netty/netty/pull/8963 adds property files which contains a netty copyright header but our old checkstyle regex did not correct detect these.
Modifications:
Update to new netty-build which contains an updated regex.
Result:
Be able to correctly detect copyright headers in property files.
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:
While we are not yet quite sure if we want to require Java11 as minimum we are at least sure we want to use java8 as minimum.
Modifications:
Change minimum version to java8 and update some tests which failed compilation after this change.
Result:
Use Java8 as minimum and be able to use Java8 features.
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:
This transport is unique because it uses Java's blocking IO (java.io / java.net) under the hood. However it is not clear if this transport is actually useful so it should be removed.
Modifications:
- Remove OIO transport and RXTX transport which depend on it.
- Remove Oio*Sctp* implementations
- Remove PerThreadEventLoop* which was only used by OIO transport.
Result:
Fixes https://github.com/netty/netty/issues/8510.
Motivation:
The UDT transport was marked as @Deprecated a long time ago as the underlying native library is not really maintained anymore. We should remove it as part of Netty 5.
Modifications:
Remove UDT transport
Result:
Dont try to maintain a transport which uses an unmaintained native lib internally.
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.
Motivation:
The maven surefire plugin will trim stacktraces by default which makes these kind of use-less when trying to understand why an test failed because one was thrown.
Modifications:
Configure the plugin to not trim the stacktrace.
Result:
Easier to debug test-failures.
Netty/Transport/Native/Epoll project can be build on aarch64 platform as well.
Motivation:
To provide the support for AARCH64 architecture
Modification:
Adjusted regex for enforce plugin to also allow AARCH64.
Result:
Be able to compile on AARCH64
Motivation:
Java 11 will be out soon, so we should be able to build (and run tests) netty.
Modifications:
- Add dependency that is needed till Java 11
- Adjust tests so these also pass on Java 11 (SocketChannelImpl.close() behavious a bit differently now).
Result:
Build also works (and tests pass) on Java 11.
Motivation:
cff87de44c updated jboss-marshalling to 2.0.5.Final but this broke the ability to run tests with Java 7.
Modifications:
Only use 2.0.5.Final if compiled against Java 10 (as before 1.4.x works fine).
Result:
Be able to run tests with Java 7 on the CI.
Motivation:
Java 10 is out so we should be able to build netty with it (and run the tests).
Modifications:
- Update Mockito and JBoss Marshalling to support Java 10
- Fix unit test to not depend on specific cipher which is not present in Java 10 anymore
Result:
Netty builds (and runs all tests) when using Java 10
Motivation:
Currently, the testing-osgi is set to skip if run with java>=9. That is not necessary when using a newer version of Felix.
Modification:
Update to Felix framework 5.6.10 (which has better jpms support), add some more --add-opens to not have WARN messages, and remove the skipOsgiTestsuite setting from the parent pom.
Result:
OSGi tests run and pass on java>=9.
Motivation:
A new version of os-maven-plugin has been released.
Modifications:
- Update os-maven-plugin from 1.5.0 to 1.6.0
Result:
- No visible changes
- Feels good
Motivation:
We need to update jetty-alpn-agent to support java 1.8.0_162 while running our tests / examples.
Modifications:
Update jetty-alpn-agent to 2.0.7
Result:
All tests alpn related tests work again on latest java8 version
Motivation:
Conscrypt is now 1.0. No more need to depend on release candidates.
Modifications:
Just the version bump. Things seemed compatible.
Result:
Depending on first guaranteed-api-stable release of Conscrypt.
Motivation:
In environments with a security manager, the reflective access to get the reference to
Throwable#addSuppressed can cause issues that result in Netty failing to load. The main
motivation in this pull request is to remove the use of reflection to prevent issues in
these environments.
Modifications:
ThrowableUtil no longer uses Class#getDeclaredMembers to get the Method that references
Throwable#addSuppressed and instead guards the call to Throwable#addSuppressed with a
Java version check.
Additionally, a annotation was added that suppresses the animal sniffer java16 signature
check on the given method. The benefit of the annotation is that it limits the exclusion
of Throwable to just the ThrowableUtil class and has string text indicating the reason
for suppressing the java16 signature check.
Result:
Netty no longer requires the use of Class#getDeclaredMethod for ThrowableUtil and will
work in environments restricted by a security manager without needing to grant reflection
permissions.
Fixes#7614
Motivation:
Our tests are often asynchronous and have timeouts to avoid hanging indefinitely. However sometimes the timeouts maybe set to low for the CI servers. It would be helpful to confirm if the application was busy with GC and if that was a contributing factor to the test timing out.
Modifications:
- Unit tests should run with -XX:+PrintGCDetails by default
Result:
More visibility into GC behavior in unit tests.
Motivation:
H2Spec is a conformance testing tool for HTTP/2 implementation.
To help us fix failing tests and avoid future regression we
should run h2spec as part of the build
Modifications:
- Add testsuite-http2 module to the project
Result:
- Run h2spec as part of the build
- 22 tests are currently ignored, we should remove the ignore as we fix them
Automatic-Module-Name entry provides a stable JDK9 module name, when Netty is used in a modular JDK9 applications. More info: http://blog.joda.org/2017/05/java-se-9-jpms-automatic-modules.html
When Netty migrates to JDK9 in the future, the entry can be replaced by actual module-info descriptor.
Modification:
The POM-s are configured to put the correct module names to the manifest.
Result:
Fixes#7218.
infinite loop
Motivation:
If SslHandler sets jdkCompatibilityMode to false and ReferenceCountedOpenSslEngine sets jdkCompatibilityMode to true there is a chance we will get stuck in an infinite loop if the peer sends a TLS packet with length greater than 2^14 (the maximum length allowed in the TLS 1.2 RFC [1]). However there are legacy implementations which actually send larger TLS payloads than 2^14 (e.g. OpenJDK's SSLSessionImpl [2]) and in this case ReferenceCountedOpenSslEngine will return BUFFER_OVERFLOW in an attempt to notify that a larger buffer is to be used, but if the buffer is already at max size this process will repeat indefinitely.
[1] https://tools.ietf.org/html/rfc5246#section-6.2.1
[2] http://hg.openjdk.java.net/jdk8u/jdk8u/jdk/file/d5a00b1e8f78/src/share/classes/sun/security/ssl/SSLSessionImpl.java#l793
Modifications:
- Support TLS payload sizes greater than 2^14 in ReferenceCountedOpenSslEngine
- ReferenceCountedOpenSslEngine should throw an exception if a
BUFFER_OVERFLOW is impossible to rectify
Result:
No more infinite loop in ReferenceCountedOpenSslEngine due to
BUFFER_OVERFLOW and large TLS payload lengths.
Motivation:
We need to upgrade our dependencies to versions which use ASM 6.0.0+ to support compiling on java9.
Modifications:
Update animal-sniffer-maven-plugin and maven-shade-plugin.
Result:
Fixes https://github.com/netty/netty/issues/6100
Motivation:
Getting the latest Conscrypt goodies.
Modifications:
A few API changes have occurred, specifically in the Conscrypt
class.
Result:
Netty now builds and tests against Conscrypt 1.0.0.RC11
Motivation:
Netty is unable to use Java9s ALPN support atm.
Modifications:
When running on Java9+ we invoke the correct methods that are exposed on the Java9+ implementation of SSLEngine and so be able to support ALPN.
This patch is based on the work of @rschmitt and so https://github.com/netty/netty/pull/6992.
Result:
Fixes#6933.
Motivation:
Remove Unsafe dependency for Atomic queues in JCTools, resolved in version 2.1.0
Modification:
Change pom JCTools version
Result:
Fixes#7117
Motivation:
We recently changed netty-tcnative to use underscores in its native library names.
Modifications:
Update code to use underscores when loading native library.
Result:
More consistent code.
Motivation:
To be able to build with latest java9 release we need to adjust commons-lang version and maven-enforcer-plugin.
Modifications:
- Use commons-lang 2.6.0
- Use maven-enforcer-plugin 3.0.0.M1 when building with java9
Result:
Netty builds again with latest java9 release
Motivation:
We used asm 6.0_ALPHA when building on java9 as the latest stable release not works with java9. asm 6.0_BETA was just released so we should update.
Modifications:
Upgrade asm version
Result:
Not use ALPHA release anymore
Motivation:
Starting with 1.0.0.RC9, conscrypt supports a buffer allocator.
Modifications:
- Updated the creation process for the engine to pass through the
ByteBufAllocator.
- Wrap a ByteBufAllocator with an adapter for conscrypt.
- Added a property to optionally control whether conscrypt uses
Netty's buffer allocator.
Result:
Netty+conscrypt will support using Netty's ByteBufAllocator.
