Permit h2 PRIORITY frames with a dependency on the connection (#10473)
Motivation:

Setting a dependency on the connection is normal and permitted; streams
actually default to depending on the connection. Using a PRIORITY frame
with a dependency on the connection could reset a previous PRIORITY,
change the relative weight, or make all streams dependent on one stream.

The previous code was disallowing these usages as it considered
depending on the connection to be a validation failure.

Modifications:

Loosen validation check to also allow depending on the connection. Fix
error message when the validation check fails.

Result:

Setting a dependency on connection would be permitted. Fixes #10416

Cleanup Conscrypt initialization (#10466)
Motivation:

How we init our static fields in Conscrypt was kind of error-prone and may even lead to NPE later on when methods were invoked out of order.

Modifications:

- Move all the init code to a static block
- Remove static field which is not needed anymore

Result:

Cleanup and also fixes https://github.com/netty/netty/issues/10413

Fix overflow bug in GenericEventExecutorChooser (#10468)
Motivation:
 The executor chooser should pluck executors in round-robin, but at the 32-bit
 overflow boundary, the round-robin sequence was disrupted when the number of
 executors are not a power of 2.

Modification:
 Changed the index counter from a 32-bit to a 64-bit long. The overflow bug is
 still technically there, but it now takes so long to reach that it will never
 happen in practice. For example, 2^63 nanoseconds is almost 300 years.

Result:
 The round-robin behaviour for all EventExecutorChoosers is now preserved in
 practice.
 This fixes #10423.

Avoid name-clash with future java.lang.Record (#10470)
Motivation:
 Recent Intellij versions are starting to anticipate
 future versions of Java that include a
 `java.lang.Record` class, and the Intellij compiler
 gets confused by the `Record` class in our
 `ResorceLeakDetector`.

Modification:
 Rename our `Record` class to `TracerRecord`.
 This matches what the class is doing, while avoiding
 any future name clashes.

Result:
 Intellij can now compile the project again, even when
 configured to use a future (snapshot or early access)
 version of Java.

Fix netty_unix_errors.c compilation on MacOS (#10469)
Motivation:
 The feature test macros did not work as expected on MacOS, so we ended up compiling for the GNU
 variant which resulted in compilation errors.
Modification:
 Add `__APPLE__` as another indicator to use the XSI variant of `strerror_r`.
Result:
 The project now once again compiles on MacOS.

Use strerror_r for JNI error messages. (#10463)
Motivation:
We previously relied on `strerror`, but this function is unfortunately not thread-safe.

Modification:
The use of `strerror` has been changed to `strerror_r`, which is thread-safe.
This function has a more complicated API, and has portability concerns that needs to be handled.
This accounts for the relatively large increase in lines of code.

Result:
Error messages from JNI are now always generated in a thread-safe way.

If user explicit ask to use an Inet6Address we should try to do so in… (#10415)
Motivation:

Even if the system does not support ipv6 we should try to use it if the user explicit pass an Inet6Address. This way we ensure we fail and not try to convert this to an ipv4 address internally.

This incorrect behavior was introduced by 70731bfa7e

Modifications:

If the user explicit passed an Inet6Address we force the usage of ipv6

Enable TLS1.3 by default of JDK SSLEngine implementation does by default (#10451)
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.

Add whitelist entry to BlockHound config to workaround issue when TLS… (#10459)
Motivation:

SSLEngineImpl.unwrap(...) may call FileInputStream.read(...) internally when TLS1.3 is used. This will cause an BlockingOperationError when BlockHound is enabled.

For more details see https://mail.openjdk.java.net/pipermail/security-dev/2020-August/022271.html

Modifications:

- Add whitelist entry to BlockHound config for now
- Update NettyBlockHoundIntegrationTest to include testing for this workaround

Result:

No BlockingOperationError when TLS1.3 is used with JDK SSL implementation and BlockHound is enabled

Fix #10449, buffer.getBytes(...) not change a file channel position (#10453)
Motivation:

Regression appeared after making changes in fix #10360 .
The main problem here that `buffer.getBytes(buffer.readerIndex(), fileChannel, fileChannel.position(), localsize)`
doesn't change channel position after writes.

Modification:

Manually set position according to the written bytes.

Result:

Fixes #10449 .

Create a new h2 stream only if the parent channel is still active (#10444)
Motivation:

If a request to open a new h2 stream was made from outside of the
EventLoop it will be scheduled for future execution on the EventLoop.
However, during the time before the `open0` task will be executed the
parent channel may already be closed. As the result,
`Http2MultiplexHandler#newOutboundStream()` will throw an
`IllegalStateException` with the message that is hard to
interpret correctly for this use-case: "Http2FrameCodec not found. Has
the handler been added to a pipeline?".

Modifications:

- Check that the parent h2 `Channel` is still active before creating a
new stream when `open0` task is picked up by EventLoop;

Result:

Users see a correct `ClosedChannelException` in case the parent h2
`Channel` was closed concurrently with a request for a new stream.

New H2 stream promise may never complete (#10443)
Motivation:

`Http2StreamChannelBootstrap#open0` invokes
`Http2MultiplexHandler#newOutboundStream()` which may throw an
`IllegalStateException`. In this case, it will never complete
the passed promise.

Modifications:

- `try-catch` all invocations of `newOutboundStream()` and fail
promise in case of any exception;

Result:

New H2 stream promise always completes.

Do not try to use Unsafe.staticFieldOffset() method under a native image. (#10428)
Motivation:

GraalVM's native images built with native-image tool do not support Unsafe.staticFieldOffset() method (at least, currently). If an application using Netty (and causing initialization of io.netty.util.internal.PlatformDependent0 class) is built into a native image and run, this results in the following error thrown during initialization:

Exception in thread "main" com.oracle.svm.core.jdk.UnsupportedFeatureError: Unsupported method of Unsafe
	at com.oracle.svm.core.util.VMError.unsupportedFeature(VMError.java:86)
	at jdk.internal.misc.Unsafe.staticFieldOffset(Unsafe.java:230)
	at sun.misc.Unsafe.staticFieldOffset(Unsafe.java:662)
	at io.netty.util.internal.PlatformDependent0$5.run(PlatformDependent0.java:294)
	at java.security.AccessController.doPrivileged(AccessController.java:83)
	at io.netty.util.internal.PlatformDependent0.<clinit>(PlatformDependent0.java:279)

This seems to be the reason of the behavior described in #10051.

Modification:

The idea of this commit is to only invoke Unsafe.staticFieldOffset() is we are not in a native image; if we are, behave like if we could not find the field at all.

GraalDetector is borrowed from Spring framework.

Result:

Fixes #10051

If we cancel the returned future of resolve query, we may get LEAK. Try to release the ByteBuf if netty can't pass the DnsRawRecord to the caller.

Modification:

Using debug mode I saw there are two places that don't handle trySuccess with release. Try to release there.

Making AES_128_GCM_SHA256 have a higher priority over CHACHA20_POLY1305_SHA256 on HTTP2 (#10418)
Motivation:

From the recent benchmark using gRPC-Java based on Netty's HTTP2, it appears that it prefers `ECDHE_ECDSA_WITH_CHACHA20_POLY1305_SHA256` over `ECDHE_ECDSA_WITH_AES_128_GCM_SHA256` since it uses the Netty HTTPS Cipher list as is. Both are considered safe but `ECDHE_ECDSA_WITH_AES_128_GCM_SHA256` has a good chance to get more optimized implementation. (e.g. AES-NI) When running both on GCP Intel Haswell VM, `TLS_ECDHE_ECDSA_WITH_CHACHA20_POLY1305_SHA256` spent 3x CPU time than `TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256`. (Note that this VM supports AES-NI)

From the cipher suites listed on `Intermediate compatibility (recommended)` of [Security/Server Side TLS](https://wiki.mozilla.org/Security/Server_Side_TLS#Modern_compatibility), they have a cipher preference which is aligned with this PR.

```

Modification:

Moving up `AES_128_GCM_SHA256` in the CIPHERS of HTTPS so that it gets priority.

Result:

When connecting to the server supporting both `ECDHE_ECDSA_WITH_AES_128_GCM_SHA256` and `ECDSA_WITH_CHACHA20_POLY1305_SHA256` and respecting the client priority of cipher suites, it will be able to save significant cpu time when running it on machines with AES-NI support.

Make the TLSv1.3 check more robust and not depend on the Java version… (#10409)
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.

Review PooledByteBufAllocator in respect of jemalloc 4.x changes and update allocate algorithm.(#10267)
Motivation:

For size from 512 bytes to chunkSize, we use a buddy algorithm. The

Modify OpenSSL native library loading to accommodate GraalVM (#10395)
**Motivation:**

We are interested in building Netty libraries with Ahead-of-time compilation with GraalVM. We saw there was [prior work done on this](https://github.com/netty/netty/search?q=graalvm&unscoped_q=graalvm). We want to introduce a change which will unblock GraalVM support for applications using netty and `netty-tcnative`.

This solves the error [that some others encounter](https://github.com/oracle/graal/search?q=UnsatisfiedLinkError+sslOpCipherServerPreference&type=Issues):

```
Exception in thread "main" java.lang.UnsatisfiedLinkError: io.grpc.netty.shaded.io.netty.internal.tcnative.NativeStaticallyReferencedJniMethods.sslOpCipherServerPreference()I [symbol: Java_io_grpc_netty_shaded_io_netty_internal_tcnative_NativeStaticallyReferencedJniMethods_sslOpCipherServerPreference or Java_io_grpc_netty_shaded_io_netty_internal_tcnative_NativeStaticallyReferencedJniMethods_sslOpCipherServerPreference__]
```

**Modification:**

The root cause of the issue is that in the tcnative libraries, the [`SSL.java` class](783a8b6b69/openssl-dynamic/src/main/java/io/netty/internal/tcnative/SSL.java (L67)) references a native call in the static initialization of the class - the method `sslOpCipherServerPreference()` on line 67 is used to initialize the static variable. But you see that `OpenSsl` also uses[ `SSL.class` to check if `netty-tcnative` is on the classpath before loading the native library](cbe238a95b/handler/src/main/java/io/netty/handler/ssl/OpenSsl.java (L123)). 

So this is the problem because in ahead-of-time compilation, when it references the SSL class, it will try to load those static initializers and make the native library call, but it cannot do so because the native library has not been loaded yet since the `SSL` class is being referenced to check if the library should be loaded in the first place.

**Solution:** So the proposed solution here is to just choose a different class in the `tcnative` package which does not make a native library call during static initialization. I just chose `SSLContext` if this is OK.

This should have no negative effects other than unblocking the GraalVM use-case.

**Result:**

It fixes the unsatisfied link error. It will fix error for future users; it is a common error people encounter.

Add option to HttpObjectDecoder to allow duplicate Content-Lengths (#10349)
Motivation:

Since https://github.com/netty/netty/pull/9865 (Netty 4.1.44) the
default behavior of the HttpObjectDecoder has been to reject any HTTP
message that is found to have multiple Content-Length headers when
decoding. This behavior is well-justified as per the risks outlined in
https://github.com/netty/netty/issues/9861, however, we can see from the
cited RFC section that there are multiple possible options offered for
responding to this scenario:

> If a message is received that has multiple Content-Length header
> fields with field-values consisting of the same decimal value, or a
> single Content-Length header field with a field value containing a
> list of identical decimal values (e.g., "Content-Length: 42, 42"),
> indicating that duplicate Content-Length header fields have been
> generated or combined by an upstream message processor, then the
> recipient MUST either reject the message as invalid or replace the
> duplicated field-values with a single valid Content-Length field
> containing that decimal value prior to determining the message body
> length or forwarding the message.

https://tools.ietf.org/html/rfc7230#section-3.3.2

Netty opted for the first option (rejecting as invalid), which seems
like the safest, but the second option (replacing duplicate values with
a single value) is also valid behavior.

Modifications:

* Introduce "allowDuplicateContentLengths" parameter to
HttpObjectDecoder (defaulting to false).
* When set to true, will allow multiple Content-Length headers only if
they are all the same value. The duplicated field-values will be
replaced with a single valid Content-Length field.
* Add new parameterized test class for testing different variations of
multiple Content-Length headers.

Result:

This is a backwards-compatible change with no functional change to the
existing behavior.

Note that the existing logic would result in NumberFormatExceptions
for header values like "Content-Length: 42, 42". The new logic correctly
reports these as IllegalArgumentException with the proper error message.

Additionally note that this behavior is only applied to HTTP/1.1, but I
suspect that we may want to expand that to include HTTP/1.0 as well...
That behavior is not modified here to minimize the scope of this change.

When BlockHound is installed,
ReferenceCountedOpenSslClientContext$ExtendedTrustManagerVerifyCallback.verify
is reported as blocking call.

Modifications:

Add allowBlockingCallsInside configuration for
ReferenceCountedOpenSslClientContext$ExtendedTrustManagerVerifyCallback.verify

Correctly include TLS1.3 ciphers in the enabled ciphersuites when using BoringSSL (#10388)
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

Fix #10378,ResourceLeakDetectorFactory.newResourceLeakDetector(Class, int) ignores  sampling interval (#10383)
Motivation:

newResourceLeakDetector(...) did not correctly pass the samplingInterval parameter and so it was ignored.

Modification:

ResourceLeakDetectorFactory.newResourceLeakDetector(Class, int) use the second parameter as the sampling interval of the newly created ResourceLeakDetector.

Result:

Fixes #10378

Ensure we preserve the original cause of the SSLException in all case… (#10372)
Motivation:

We did not correctly preserve the original cause of the SSLException when all the following are true:

 * SSL_read failed
 * handshake was finished
 * some outbound data was produced durigin SSL_read (for example ssl alert) that needs to be picked up by wrap(...)

Modifications:

Ensure we correctly preserve the original cause of the SSLException and rethrow it once we produced all data via wrap(...)

Result:

Be able to understand why we see an error in all cases

The bounded Mpsc Queue for no Unsafe users behave differently from Unsafe ones (#10377)
Motivation:

Unsafe users are getting MpscChunkedArrayQueue while no Unsafe ones MpscGrowableAtomicArrayQueue

Modifications:

MpscChunkedAtomicArrayQueue should be used for no Unsafe users (matching MpscChunkedArrayQueue behaviour)

Result:

no Unsafe users uses MpscChunkedAtomicArrayQueue while allocating bounded Mpsc Queues

Ensure we feed all data to the SSLEngine during handshaking in our tests (#10373)
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

Ensure ApplicationProtocolNegotiationHandler does handle handshake fa… (#10363)
Motivation:

When ApplicationProtocolNegotiationHandler is in the pipeline we should expect that its handshakeFailure(...) method will be able to completly handle the handshake error. At the moment this is not the case as it only handled SslHandshakeCompletionEvent but not the exceptionCaught(...) that is also triggered in this case

Modifications:

- Call handshakeFailure(...) in exceptionCaught and so fix double notification.
- Add testcases

Result:

Fixes https://github.com/netty/netty/issues/10342

Expand ChannelPipeline javadocs to cover UnorderedThreadPoolEventExecutor (#10361)
Motivation:

Seems like some users are suprised by the behaviour of DefaultEventExecutor when used within the ChannelPipeline. We should clarify the semantics and also mention UnordedThreadPoolEventExecutor which may be more inline with their expectations

Modifications:

Add javadocs section about UnorderedThreadPoolEventExecutor and expand details for DefaultEventExecutor

Result:

Clarify sematics

Fix memory leak in AbstractDiskHttpData when CompositeByteBuf is used (#10360)
Motivation:

AbstractDiskHttpData may cause a memory leak when a CompositeByteBuf is used. This happened because we may call copy() but actually never release the newly created ByteBuf.

Modifications:

- Remove copy() call and just use ByteBuf.getBytes(...) which will internally handle the writing to the FileChannel without any extra copies that need to be released later on.
- Add unit test

Result:

Fixes https://github.com/netty/netty/issues/10354
