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.
Motivation:
JCTools 2.0.2 provides an unbounded MPSC linked queue. Before we shaded JCTools we had our own unbounded MPSC linked queue and used it in various places but gave this up because there was no public equivalent available in JCTools at the time.
Modifications:
- Use JCTool's MPSC linked queue when no upper bound is specified
Result:
Fixes https://github.com/netty/netty/issues/5951
Motivation:
Docker's `--tmpfs` flag mounts the temp volume with `noexec` by default,
resulting in an UnsatisfiedLinkError. While this is good security
practice, it is a surprising failure from a seemingly innocuous flag.
Modifications:
Add a best-effort attempt in `NativeLibraryLoader` to detect when temp
files beng loaded cannot be executed even when execution permissions
are set, often because the `noexec` flag is set on the volume.
Requires numerous additional exclusions to the Animal Sniffer config
for Java7 POSIX permissions manipulation.
Result:
Fixes [#6678].
Motivation:
As we now include native code for multiple platforms we need to generate an uber all jar before release it from the staging repository. For this the uber-staging profile can be used. To create a snapshot uber jar the uber-snapshot profile can be used.
Modifications:
- Add uber-staging and uber-snapshot profile
- Correct comment in pom.xml file to show usage.
Result:
Easier to create snapshot and release uber jars.
Motivation:
To ensure the release plugin works correctly we need to ensure all modules are included during build.
Modification:
- Include all modules
- Skip compilation and tests for native code when not supported but still include the module and build the jar
Result:
Build and release works again
Motivation:
When adding SNIMatcher support we missed to use static delegating methods and so may try to load classes that not exists in Java7. Which will lead to errors.
Modifications:
- Correctly only try to load classes when running on java8+
- Ensure Java8+ related tests only run when using java8+
Result:
Fixes [#6700]
Motivation:
We currently don't have a native transport which supports kqueue https://www.freebsd.org/cgi/man.cgi?query=kqueue&sektion=2. This can be useful for BSD systems such as MacOS to take advantage of native features, and provide feature parity with the Linux native transport.
Modifications:
- Make a new transport-native-unix-common module with all the java classes and JNI code for generic unix items. This module will build a static library for each unix platform, and included in the dynamic libraries used for JNI (e.g. transport-native-epoll, and eventually kqueue).
- Make a new transport-native-unix-common-tests module where the tests for the transport-native-unix-common module will live. This is so each unix platform can inherit from these test and ensure they pass.
- Add a new transport-native-kqueue module which uses JNI to directly interact with kqueue
Result:
JNI support for kqueue.
Fixes https://github.com/netty/netty/issues/2448
Fixes https://github.com/netty/netty/issues/4231
Motivation:
There needs to be some work be done to allow using forbidden API check plugin when using java9.
Modifications:
Skip forbidden API check when using java9
Result:
Builds again with java9
Motivation:
In cases when an application is running in a container or is otherwise
constrained to the number of processors that it is using, the JVM
invocation Runtime#availableProcessors will not return the constrained
value but rather the number of processors available to the virtual
machine. Netty uses this number in sizing various resources.
Additionally, some applications will constrain the number of threads
that they are using independenly of the number of processors available
on the system. Thus, applications should have a way to globally
configure the number of processors.
Modifications:
Rather than invoking Runtime#availableProcessors, Netty should rely on a
method that enables configuration when the JVM is started or by the
application. This commit exposes a new class NettyRuntime for enabling
such configuraiton. This value can only be set once. Its default value
is Runtime#availableProcessors so that there is no visible change to
existing applications, but enables configuring either a system property
or configuring during application startup (e.g., based on settings used
to configure the application).
Additionally, we introduce the usage of forbidden-apis to prevent future
uses of Runtime#availableProcessors from creeping. Future work should
enable the bundled signatures and clean up uses of deprecated and
other forbidden methods.
Result:
Netty can be configured to not use the underlying number of processors,
but rather the constrained number of processors.
