Hide Recycler implemention to allow experimenting with different implementions of an Object pool (#9715)
Motivation:

At the moment we directly extend the Recycler base class in our code which makes it hard to experiment with different Object pool implementation. It would be nice to be able to switch from one to another by using a system property in the future. This would also allow to more easily test things like https://github.com/netty/netty/pull/8052.

Modifications:

- Introduce ObjectPool class with static method that we now use internally to obtain an ObjectPool implementation.
- Wrap the Recycler into an ObjectPool and return it for now

Result:

Preparation for different ObjectPool implementations

aba9b34a59 Accept Iterable as argument to SslContextBuilder methods. (#9711)
Motivation:

It is common, especially in frameworks, for the parameters to `SslContextBuilder` methods to be built up as a `List` or similar `Iterable`. It is currently difficult to use `SslContextBuilder` in this case because it requires a conversion to array.

Modification:

Add overloads for methods that accept varargs to also accept `Iterable`, delegating by copying into an array.

Result:

Fixes #9293

2f32e0b8ad Changed Netty JDK SSL to use default protocols instead of hardcoded supported (#9707)
Motivation:

Netty should respect JVM flags to control SSL protocols, eg. `-Djdk.tls.client.protocols`


Modification: 

Changed `JdkSslContext` to use `SSLContext.getDefaultSSLParameters().getProtocols()` instead of `engine.getSupportedProtocols()` which is hardcoded as `SSLv2Hello, SSLv3, TLSv1, TLSv1.1, TLSv1.2`.

Result:

Without `-Djdk.tls.client.protocols`, `SSLContext.getDefaultSSLParameters().getProtocols()` returns `TLSv1, TLSv1.1, TLSv1.2`.

With `-Djdk.tls.client.protocols=TLSv1.2`, `SSLContext.getDefaultSSLParameters().getProtocols()` returns `TLSv1.2`.

Fixes #9706

ff9df03d21 Make only default IdleStateEvents cached string representation (#9705)
Motivation:

In PR https://github.com/netty/netty/pull/9695   IdleStateEvents
were made to cache their string representation.   The reason for this
was to avoid creating garbage as these values would be used frequently.
However, these objects may be used on multiple event loops and this
may cause an unexpected race to occur.

Modification:
Only make the events that Netty creates cache their toString representation.

Result:
No races.

Refactor SslHandler internals to always use heap buffers for JDK SSLE… (#9696)
Motivation:

We should aim to always use heap buffers when using the JDK SSLEngine for now as it wants to operate on byte[] and so will do internal memory copies if a non heap buffer is used. Beside this it will always return BUFFER_OVERFLOW when a smaller buffer then 16kb is used when calling wrap(...) (even if a very small amount of bytes should be encrypted). This can lead to excercive direct memory usage and pressure for no good reason.

Modifications:

Refactor internals of SslHandler to ensure we use heap buffers for the JDK SSLEngine impelementation

Result:

Less direct memory usage when JDK SSLEngine implementation is used

### Motivation:

FlowControllerHandler currently may swell read-complete events in some situations.

* Fire read-complete event from flow controller, when it previously was swallowed
* New unit test to cover this case

a77fe9333d Add 'toString' method into IdleStateEvent (#9695)
### Motivation:

IdleStateEvent is very convenient and frequently used type of events. However both in runtime (logs) and in debug you need some manual steps to see their actual content. Default implementation generates worthless trash like this:

    io.netty.handler.timeout.IdleStateEvent@27f674d

There are examples already, where event has convenient and useful toString implementation:

* io.netty.handler.proxy.ProxyConnectionEvent
* io.netty.handler.ssl.SslCompletionEvent

### Modification:

* Implement 'IdleStateEvent.toString' method.
* Unit test.

### Result:

More useful String representation of IdleStateEvent

b3fb2eb27f Add a utility that checks if the a SslProvider supports ALPN (#9693)
Motivation:

We have a public utility `OpenSsl.isAlpnSupported()` that helps users to
check if ALPN is available for `SslProvider.OPENSSL`. However, we do not
provide a similar utility for `SslProvider.JDK`. Therefore, users who
configured ALPN with `SslProvider.JDK` will get a runtime exception at
the time when a new connection will be created.

Modifications:

- Add public `SslProvider.isAlpnSupported(SslProvider)` utility method
that returns `true` if the `SslProvider` supports ALPN;
- Deprecate `OpenSsl.isAlpnSupported()`;

Result:

Users can verify if their environment supports ALPN with
`SslProvider` upfront (at bootstrap), instead of failing with
runtime exception when a new connection will be created.

ec8d43c294 Do not mandate direct bytes in SslHandler queue (#9656)
Motivation:

Currently when the SslHandler coalesces outbound bytes it always
allocates a direct byte buffer. This does not make sense if the JDK
engine is being used as the bytes will have to be copied back to heap
bytes for the engine to operate on them.

Modifications:

Inspect engine type when coalescing outbound bytes and allocate heap
buffer if heap bytes are preferred by the engine.

Result:

Improved performance for JDK engine. Better performance in environments
without direct buffer pooling.

Fix SSL tests that use SslProvider.OPENSSL_REFCNT (#9649)
Motivation:

031c2e2e88 introduced some change to reduce the risk of have the `ReferenceCountedOpenSslContext` be destroyed while the `ReferenceCountedSslEngine` is still in us. Unfortunaly it missed to adjust a few tests which make assumptions about the refCnt of the context.

Modifications:

Adjust tests to take new semenatics into acount.

031c2e2e88 Reference-counted SslEngines retain a reference to their parent SslContext (#9626)
Motivation:
With the Netty ref-counted OpenSSL implementation the parent SslContext
maintains state necessary for the SslEngine's it produces. However, it's
possible for the parent context to be closed and release those resources
before the child engines are finished which causes problems.

Modification:
Spawned ReferenceCountedOpenSslEngine's retain a reference to their
parent ReferenceCountedOpenSslContext.

Result:
The lifetime of the shared data is extended to include the lifetime of
the dependents.

eb3c4bd926 ChunkedNioFile can use absolute FileChannel::read to read chunks (#9592)
Motivation:

Users can reuse the same FileChannel for different ChunkedNioFile
instances without being worried that FileChannel::position will be
changed concurrently by them.
In addition, FileChannel::read with absolute position allows to
use on *nix pread that is more efficient then fread.

Modifications:

Always use absolute FileChannel::read ops

Result:

Faster and more flexible uses of FileChannel for ChunkedNioFile

Fix *SslEngineTest to not throw ClassCastException and pass in all cases (#9588)
Motivation:

Due some bug we did endup with ClassCastExceptions in some cases. Beside this we also did not correctly handle the case when ReferenceCountedOpenSslEngineTest did produce tasks to run in on test.

Modifications:

- Correctly unwrap the engine before to fix ClassCastExceptions
- Run delegated tasks when needed.

Result:

All tests pass with different OpenSSL implementations (OpenSSL, BoringSSL etc)

Correctly handle task offloading when using BoringSSL / OpenSSL (#9575)
Motivation:

We did not correctly handle taskoffloading when using BoringSSL / OpenSSL. This could lead to the situation that we did not write the SSL alert out for the remote peer before closing the connection.

Modifications:

- Correctly handle exceptions when we resume processing on the EventLoop after the task was offloadded
- Ensure we call SSL.doHandshake(...) to flush the alert out to the outboundbuffer when an handshake exception was detected
- Correctly signal back the need to call WRAP again when a handshake exception is pending. This will ensure we flush out the alert in all cases.

Result:

No more failures when task offloading is used.

Correctly synchronize before trying to set key material to fix possible native crash (#9566)
Motivation:

When using io.netty.handler.ssl.openssl.useTasks=true we may call ReferenceCountedOpenSslEngine.setKeyMaterial(...) from another thread and so need to synchronize and also check if the engine was destroyed in the meantime to eliminate of the possibility of a native crash.
The same is try when trying to access the authentication methods.

Modification:

- Add synchronized and isDestroyed() checks where missing
- Add null checks for the case when a callback is executed by another thread after the engine was destroyed already
- Move code for master key extraction to ReferenceCountedOpenSslEngine to ensure there can be no races.

Result:

No native crash possible anymore when using io.netty.handler.ssl.openssl.useTasks=true

21720e4a78 Allow to build on powerpc
Motivation:

At the moment it is not possible to build netty on a power 8 systems.

Modifications:

- Improve detection of the possibility of using Conscrypt
- Skip testsuite-shading when not on x86_64 as this is the only platform for which we build tcnative atm
- Only include classifier if on x86_64 for tcnative as dependency as this is the only platform for which we build tcnative atm
- Better detect if UDT test can be run

b7e9829a49 Update GraalVM Native Image configuration. (#9515)
Motivation:

The Netty classes are initialized at build time by default for GraalVM Native Image compilation. This is configured via the `--initialize-at-build-time=io.netty` option. While this reduces start-up time it can lead to some problems:

 - The class initializer of `io.netty.buffer.PooledByteBufAllocator` looks at the maximum memory size to compute the size of internal buffers. If the class initializer runs during image generation, then the buffers are sized according to the very large heap size that the image generator uses, and Netty allocates several arrays that are 16 MByte. The fix is to initialize the following 3 classes at run time: `io.netty.buffer.PooledByteBufAllocator,io.netty.buffer.ByteBufAllocator,io.netty.buffer.ByteBufUtil`. This fix was dependent on a GraalVM Native Image fix that was included in 19.2.0.

 - The class initializer of `io.netty.handler.ssl.util.ThreadLocalInsecureRandom` needs to be initialized at runtime to ensure that the generated values are trully random and not fixed for each generated image.

 - The class initializers of `io.netty.buffer.AbstractReferenceCountedByteBuf` and `io.netty.util.AbstractReferenceCounted` compute field offsets. While the field offset recomputation is necessary for correct execution as a native image these initializers also have logic that depends on the presence/absence of `sun.misc.Unsafe`, e.g., via the `-Dio.netty.noUnsafe=true` flag. The fix is to push these initializers to runtime so that the field offset lookups (and the logic depending on them) run at run time. This way no manual substitutions are necessary either.
 
Modifications:

Add `META-INF/native-image` configuration files that correctly trigger the inialization of the above classes at run time via `--initialize-at-run-time=...` flags.
 
Result:

Fixes the initialisation issues described above for Netty executables built with GraalVM.

Always wrap X509ExtendedTrustManager when using OpenSSL and JDK < 11 (#9443)
Motivation:

When using OpenSSL and JDK < 11 is used we need to wrap the user provided X509ExtendedTrustManager to be able to support TLS1.3. We had a check in place that first tried to see if wrapping is needed at all which could lead to missleading calls of the user provided trustmanager. We should remove these calls and just always wrap if needed.

Modifications:

Always wrap if OpenSSL + JDK < 11 and TLS1.3 is supported

Result:

Less missleading calls to user provided trustmanager

8d9cea2ce0 Try to load native linux libraries with matching classifier first (#9411)
Motivation:

Users' runtime systems may have incompatible dynamic libraries to the ones our
tcnative wrappers link to. Unfortunately, we cannot determine and catch these
scenarios (in which the JVM crashes) but we can make a more educated guess on
what library to load and try to find one that works better before crashing.

Modifications:

1) Build dynamically linked openSSL builds for more OSs (netty-tcnative)
2) Load native linux libraries with matching classifier (first)

Result:

More developers / users can use the dynamically-linked native libraries.

7fc355aa05 Introduce SslMasterKeyHandler (#8653)
Motivation

Debugging SSL/TLS connections through wireshark is a pain -- if the cipher used involves Diffie-Hellman then it is essentially impossible unless you can have the client dump out the master key [1]

This is a work-in-progress change (tests & comments to come!) that introduces a new handler you can set on the SslContext to receive the master key & session id. I'm hoping to get feedback if a change in this vein would be welcomed.

An implementation that conforms to Wireshark's NSS key log[2] file is also included.

Depending on feedback on the PR going forward I am planning to "clean it up" by adding documentation, example server & tests. Implementation will need to be finished as well for retrieving the master key from the OpenSSL context.

[1] https://jimshaver.net/2015/02/11/decrypting-tls-browser-traffic-with-wireshark-the-easy-way/
[2] https://developer.mozilla.org/en-US/docs/Mozilla/Projects/NSS/Key_Log_Format

Modification

- Added SslMasterKeyHandler
- An implementation of the handler that conforms to Wireshark's key log format is included.

Result:

Be able to debug SSL / TLS connections more easily.

14154074f2 Don't loop over TLS records for SNI (#7479)
Motivation:

The AbstractSniHandler previously was willing to tolerate up to three
non-handshake records before a ClientHello that contained an SNI
extension field. This is, so far as I can tell, completely
unnecessary: no TLS implementation will be sending alerts or change
cipher spec messages before ClientHello.

Given that it was not possible to determine why this loop is in
the code to begin with, it's probably just best to remove it.

Modifications:

Remove the for loop.

Result:

The AbstractSniHandler will more rapidly determine whether it should
pass the records on to the default SSL handler.

efe40ac17d Add a test for OpenSslEngine which decrypts traffic (#8699)
Motivation:
I've introduced netty/netty-tcnative#421 that introduced exposing OpenSSL master key & client/server
random values with the purpose of allowing someone to log them to debug the traffic via auxiliary tools like Wireshark (see also #8653)

Modification:
Augmented OpenSslEngineTest to include a test which manually decrypts the TLS ciphertext
after exposing the masterkey + client/server random. This acts as proof that the tc-native new methods work correctly!

Result:
