Motivation:
We should allow server initiated renegotiation when OpenSSL / BoringSSL bases SSLEngine is used as it might be used for client auth.
Modifications:
- Upgrade netty-tcnative version to be able to allow renegotiate once
- Adjust code
Result
Fixes https://github.com/netty/netty/issues/11529
Motivation:
Make SslHandler's handlerRemoved0 method release the sslEngine
even if it fails in the middle.
See details in https://github.com/netty/netty/issues/11595.
Modifications:
Wrap the release of sslEngine into a finally block.
Result:
The sslEngine would be released eventually.

Motivation:
We tightly integrate the TrustManger and KeyManager into our native SSL implementation which means that both of them need to support TLSv1.3 as protocol. This is not always the case and so can produce runtime exceptions.
As TLSv1.3 support was backported to Java8 quite some time now we should be a bit more conservative and only enable TLSv1.3 for our native implementation if the JDK implementation supports it as well. This also allows us to remove some hacks we had in place to be able to support it before in Java8.
Modifications:
- Only enable TLSv1.3 support for our native SSL implementation when the JDK supports it as well
- Remove OpenSslTlsv13X509ExtendedTrustManager as its not needed anymore
Result:
Fixes https://github.com/netty/netty/issues/11589
Motivation:
At the moment why you try to build a SslContext via SslProvider.OPENSSL* and netty-tcnative* is not on the classpath it will fail with:
```

We should do better here.
Modifications:
Call `OpenSsl.ensureAvailability()` before trying to construct OpenSsl*Context instances
Result:
More clear error message like:

Motivation:
These cleanups were done in another PR but were not directly related to that PR.
This extracts those changes and backports them to 4.1.
Modification:
* Remove the use of mocking in DefaultPromiseTest.
* Fix a few warnings.
* Make `testStackOverFlowChainedFuturesB` test with the right listener chain.
Result:
Cleaner code.
Motivation:
At present, the verification methods of `ZstdOptions` and `BrotliOptions` are not consistent, and the processing methods of `ZstdOptions` and `BrotliOptions` in `HttpContentCompressor` are also inconsistent.
The http2 module does not add zstd-jni dependency, so `ClassNotFoundException` may be thrown
Modification:
Added `Zstd.isAvailable()` check in `ZstdOptions` to be consistent, and added zstd-jni dependency in http2 module
Result:
The verification methods of `ZstdOptions` and `BrotliOptions` are consistent, and `ClassNotFoundException` will not be thrown

Motivation:
- Fix `HttpContentCompressor` errors due to missing optional compressor libraries such as Brotli and Zstd at runtime.
- Improve support for optional encoders by only considering the `CompressionOptions` provided to the constructor and ignoring those for which the encoder is unavailable.
Modification:
The `HttpContentCompressor` constructor now only creates encoder factories for the CompressionOptions passed to the constructor when the encoder is available which must be checked for Brotli and Zstd. In case of Brotli, it is not possible to create BrotliOptions if brotly4j is not available so there's actually nothing to check. In case of Zstd, I had to create class `io.netty.handler.codec.compression.Zstd` similar to `io.netty.handler.codec.compression.Brotli` which is used to check that zstd-jni is availabie at runtime.
The `determineEncoding()` method had to change as well in order to ignore encodings for which there's no `CompressionEncoderFactory` instance.
When the HttpContentCompressor is created using deprecated constructor (ie. with no CompressionOptions), we consider all available encoders.
Result:
Fixes#11581.
Motivation:
Opportunities for clean up found while working on a different PR.
Modification:
* Dead code has been removed.
* Unnecessary parenthesis, qualifiers, etc. removed.
* Unused imports removed.
* Override annotations added where missing.
Result:
Cleaner code
Motivation:
This fixes a bug that would result in an `io.netty.channel.unix.Errors$NativeIoException: connectx(..) failed: Address family not supported by protocol family` error.
This happens when the connecting socket is configured to use IPv6 but the address being connected to is IPv4.
This can occur because, for instance, Netty and `InetAddress.getLoopbackAddress()` have different preferences for IPv6 vs. IPv4.
Modification:
Pass the correct ipv6 or ipv4 flags to connectx, depending on whether the socket was created for AF_INET or AF_INET6, rather than relying on the IP version of the destination address.
Result:
No more issue with TCP FastOpen on MacOS when using addresses of the "wrong" IP version.
Motivation:
ccef8feedd introduced some changes to share code but did introduce a regression when decoding queries.
Modifications:
- Correctly only decode one time.
- Adjust unit test
Result:
Fixes https://github.com/netty/netty/issues/11591
Motivation:
We should use StandardSocketOptions#IP_MULTICAST_IF as default source when joing multicast groups and only try to use the localAddress if this returns null.
Modifications:
First check if StandardSocketOptions#IP_MULTICAST_IF was set and if so use the network interface when joining mulicast groups
Result:
Fixes https://github.com/netty/netty/issues/11541
Motivation:
As JDK17 is really close to be released we should add a CI job for it to ensure netty works correctly when using it.
Modifications:
Add docker config and workflow config to run CI job for JDK17
Result:
Ensure netty works on JDK17 as well
Motivation:
Sometimes intellij fails to build because the compiler cant really figure out what to do. We can workaround this by adding some explicit casts.
Modifications:
Add explicits casts
Result:
No more problems with intellij
Motivation:
We should add some docs / comment to explain what io.netty.leakDetection.acquireAndReleaseOnly is all about.
Modifications:
Add some comments
Result:
Fixes https://github.com/netty/netty/issues/11576.
Motivation:
0c9a86db81 added a change to log a message if someone tried to change the TLSv1.3 ciphers when using BoringSSL. Unfortunally the code had some error and so even if the user did not change these we logged something.
Modifications:
- Ensure there are no duplicates in the ciphers
- Correctly take TLSv1.3 extra ciphers into account when using BoringSSL
Result:
Correctly log or not log
__Motivation__
Since request.headers().getAll() will never return null. And the check null condition will not work as expected.
__Modification__
Add isEmpty() checking as well.
__Result__
Fixes#11568
Motivation:
The MacOS-specific `connectx(2)` system call make it possible to establish client-side connections with TCP FastOpen.
Modification:
Add support for TCP FastOpen to the KQueue transport, and add the `connectx(2)` system call to `BsdSocket`.
Result:
It's now possible to use TCP FastOpen when initiating connections on MacOS.
Motivation:
This test is inherently flaky due to file descriptor reuse.
Even though we have taken steps to make it less flaky, it still fails sometimes.
When it does, the error message is not very helpful.
Modification:
Make use of assertThrows and assertThat to get more descriptive error messages when the tests fail.
Result:
More meaningful messages on test failures, which may help us make the tests more resilient in the future
Motivation:
There are lots of redundant variable declarations which should be inlined to make good look better.
Modification:
Made variables inlined.
Result:
Less redundant variable and more readable code.
Motivation:
TCP FastOpen is a pure optimisation, that is opportunistically applied.
There is no reason to make it specific to the epoll transport, and in the future we could add support to other transports.
Besides, the client-side equivalent, TCP_FASTOPEN_CONNECT, is already transport agnostic.
Modification:
Move the TCP_FASTOPEN channel option from EpollChannelOption to ChannelOption.
Mark the field in EpollChannelOption as deprecated.
Result:
All channel options related to TCP FastOpen are now transport agnostic.
However, we still only actually support TFO on the epoll transport.
Motivation:
io.netty.http2.validateContentLength SystemProperty was added as a way
to opt-out for compabitility for libraries/applications that violated
the RFC's content-length matching requirements [1] but have not yet been
fixed. This SystemProperty has been around for a few months now and it
is assumed these issues have now been addressed in 3rd party code.
[1] https://tools.ietf.org/html/rfc7540#section-8.1.2.6
Modifications:
- Remove the io.netty.http2.validateContentLength SystemProperty,
preventing folks from opting out of RFC's required content-length
matching.
Result:
No more escape hatch in H2 for content-length matching enforcement.
Motivation:
We should make variables `final` which are not reinstated again in code to match the code style and makes the code look better.
Modification:
Made couples of variables as `final`.
Result:
Variables marked as `final`.
Motivation:
We should keep bitwise operations simple and easy to understand.
Modification:
Simplify few Bitwise operations.
Result:
Less complicated bitwise operation code
Motivation:
We cannot control when "the system" reuses file descriptors.
This makes any test that assert on the behaviour of closed file descriptors inherently racy.
Modification:
Allow the EpollSocketChannelConfigTest socketoption tests a few tries to get the correct assertion on the behaviour of closed socket file descriptors.
Result:
The EpollSocketChannelConfigTest should now be much less flaky.
Motivation:
We should get rid of the unnecessary toString calls because they're redundant in nature.
Modification:
Removed unnecessary toString calls.
Result:
Better code
Motivation:
We should get rid of unnecessary semicolons because they don't do anything in code.
Modification:
Removed unnecessary semicolons.
Result:
Better code
Motivation:
There are lots of imports which are unused. We should get rid of them to make the code look better,
Modification:
Removed unused imports.
Result:
No unused imports.
Motivation:
This bug could occasionally cause SSL handshakes to time out, because the server-side handshake would fail to resume its event loop.
Modification:
Async delegate SSL tasks now lower their NEED_TASK status after they have executed, but before they run their completion callback.
This is important because the completion callback could be querying the handshake status.
This could cause the task delegator thread and the event look to race.
If the event look queries the handshake status first, it might think that it still needs to delegate another task.
If this happens, the delegator find a null task, and then fail to resume the event loop, causing the handshake to stall.
Result:
This data race no longer causes handshake timeouts.
Motivation:
We need to ensure we call wrap as long as there is something left to be send to the remote peer in cases of non-application data (like for example alerts).
Modifications:
Check the pending data and based on it return NEED_WRAP even when the handshake was done.
Result:
Always produce alerts etc
Motivation:
We should have guards in place to check increment or decrement count in `ReferenceCountUtil`. Increment and Decrement counts must be a positive integer.
Modification:
Added `ObjectUtil#checkPositive` checks.
Result:
Prevent release due to invalid count.
Motivation:
We the build failed we should ensure we also include hs_err* files as it may have failed due a native crash
Modifications:
Adjust path matching to include hs_err as well
Result:
Easier to debug native crashes
Motivation:
There is no decoder and encoder for TCP based DNS.
Result:
- Added decoder and encoder
- Added tests
- Added example
Result:
Be able to decode and encode TCP based dns

Motivation:
Due a bug in the statemachine we produced an decoding error when the GZIP footer was fragmented in some cases
Modifications:
- Fix statemachine
- Add testcase
Result:
Correctly decode GZIP in all cases
Motivation:
Users may want to clear the cache manually. For this it should be possible to access it first.
Modifications:
Change the visibility to public
Result:
Be able to clear the cache manually. Related to https://github.com/netty/netty/issues/11519
Motivation:
At the moment FastLzFrameEncoder depends on the buffer type. This is not needed and may cause memory copies
Modifications:
Rewrite to be able to just act on the ByteBuf
Result:
Less memory copies
