Correctly handle lifecycle of clientHello ByteBuf in SslClientHelloHandler (#10030)
Motivation:

Due incorrectly handling of reference count of the clientHello ByteBuf we may overrelease the buffer. This did show up in the log of a test:

11:55:16.595 [main] DEBUG i.n.h.ssl.SslClientHelloHandler - Unexpected client hello packet: 16030100bd010000b90303a74225676d1814ba57faff3b3663656ed05ee9dbb2a4dbb1bb1c32d2ea5fc39e0000000100008c0000001700150000164348415434e380824c45414e434c4f5544e38082434e000b000403000102000a00340032000e000d0019000b000c00180009000a00160017000800060007001400150004000500120013000100020003000f0010001100230000000d0020001e060106020603050105020503040104020403030103020303020102020203000f00010133740000

Add SslClientHelloHandler which allows to do something based on the S… (#9827)
Motivation:

Sometimes it is useful to do something depending on the Ssl ClientHello (like for example select a SslContext to use). At the moment we only allow to hook into the SNI extension but this is not enough.

Modifications:

Add SslClientHelloHandler which allows to hook into ClientHello messages. This class is now also the super class of AbstractSniHandler

Result:

More flexible processing of SSL handshakes

SSL / BlockHound works out of the box with the default SSL provider (#9969)
Motivation:

JDK is the default SSL provider and internally uses blocking IO operations.

Modifications:

Add allowBlockingCallsInside configuration for SslHandler runAllDelegate function.

Result:

When BlockHound is installed, SSL works out of the box with the default SSL provider.

SslHandler.wrap(...) must ensure it not loose the original exception when finishWrap(...) fails (#9974)
Motivation:

When SslHandler.finishWrap throws an exception, ensure that the promise and buf is not reused to avoid throwing IllegalArgumentException or IllegalReferenceCountException which causes the original exception to be lost.

Modification:

The change ensures that the values for the promise and bytebuf are nulled before calling finishWrap so that it will not be called again with the same arguments.

Result:

Fixes #9971 .

384eaf773c Set keystoreType for JdkSslClientContext Keystores (#9965)
Motivation:

In the PR #9003, the issue #8998 was supposedly solved. But actually the fix only made it so the TrustManager can use the specified keystore type instead of also supporting it in the KeyManagerFactory.

In my environment, we are using PKCS#11 Keys which are then rejected by the PKCS#12 keystore. A PKCS#12 keystore is created since the keystoreType was set to null by the code from the mentioned PR.

Modification:

Do not ignore the keystoreType parameter during the creation of the JdkSslClientContext KeyManagerFactory.

Result:

Fixes #8998.

a7de4747d0 Add ByteBufFormat option to LoggingHandler (#9915)
Motivation

LoggingHandler is a very useful tool for debugging and for tracking the
sequence of events in a pipeline. LoggingHandler also includes the
functionality to log a hex dump of all written and received ByteBufs.
This can be useful for small messages, but for large messages, this can
potentially result in extremely large logs. E.g., a 1 MB payload will
result in over a 1 MB log message being recorded. While LoggingHandler
may only be intended for debugging, this can still be too excessive in
some debugging scenarios.

Modifications

* Create a new ByteBufFormat enum that allows users to specify "SIMPLE"
or "HEX_DUMP" logging for ByteBufs.
* For all constructors that currently accept a LogLevel parameter,
create new overloaded constructors that also accept this enum as a
parameter.
* Continue to record hex dumps by default.

Result

Users will be able to opt out of full hex dump recording, if they wish
to.

Reduce allocations in ChunkedWriteHandler when processing the queued … (#9960)
Motivation:

At the moment we create a new ChannelFutureListener per chunk when trying to write these to the underlying transport. This can be optimized by replacing the seperate write and flush call with writeAndFlush and only allocate the listener if the future is not complete yet.

Modifications:

- Replace seperate write and flush calls with writeAndFlush
- Only create listener if needed, otherwise execute directly

Result:

Less allocations

Remove extra field from ChunkedWriteHandler to make it less error-prone (#9958)
Motivation:

At the moment we use an extra field in ChunedWriteHandler to hold the current write. This is not needed and makes sense even more error-prone. We can just peek in the queue.

Modifications:

Use Queue.peek() to keep track of current write

Result:

Less error-prone code

Add ResolveAddressHandler which can be used to resolve addresses on the fly (#9947)
Motivation:

At the moment resolving addresses during connect is done via setting an AddressResolverGroup on the Bootstrap. While this works most of the times as expected sometimes the user want to trigger the connect() from the Channel itself and not via the Bootstrap. For this cases we should provide a ChannelHandler that the user can use that will do the resolution.

Modifications:

Add ResolveAddressHandler and tests

Result:

Be able to resolve addresses without Bootstrap

41c47b41bf Fix event loop hang in SniHandler (#9933)
Motivation

A bug was introduced in #9806 which looks likely to be the cause of
#9919. SniHandler will enter an infinite loop if an SSL record is
received with SSL major version byte != 3 (i.e. something other than TLS
or SSL3.0)

Modifications

- Follow default path as intended  for majorVersion != 3 in
AbstractSniHandler#decode(...)
- Add unit test to reproduce the hang

Result

Fixes #9919

2be3d888e7 FlushConsolidationHandler may suppress flushes by mistake (#9931)
Motivation:

When `consolidatedWhenNoReadInProgress` is true, `channel.writeAndFlush (data) .addListener (f-> channel.writeAndFlush (data2))` Will cause data2 to never be flushed. 

Because the flush operation will synchronously execute the `channel.writeAndFlush (data2))` in the `listener`, and at this time, since the current execution thread is still an `eventloop`(`executor.inEventLoop()` was true), all handlers will be executed synchronously. At this time, since `nextScheduledFlush` is still not null, the `flush` operation of `data2` will be ignored in `FlushConsolidationHandler#scheduleFlush`.

Modification:

 - reset `nextScheduledFlush` before `ctx.flush`
 - use `ObjectUtil` to polish code

Result:

Fixes https://github.com/netty/netty/issues/9923

Correctly handle fragmented Handshake message when trying to detect SNI (#9806)
Motivation:

At the moment our AbstractSniHandler makes the assemption that Handshake messages are not fragmented. This is incorrect as it is completely valid to split these across multiple TLSPlaintext records.

Thanks to @sskrobotov for bringing this to my attentation and to @Lukasa for the help.

Modifications:

- Adjust logic in AbstractSniHandler to handle fragmentation
- Add unit tests

Result:

Correctly handle fragmented Handshake message in AbstractSniHandler (and so SniHandler).

6e3d784a2c Support Passing KeyManager and TrustManager into SslContextBuilder (#9805) (#9786)
Motivation:

This is a PR to solve the problem described here: https://github.com/netty/netty/issues/9767
Basically this PR is to add two more APIs in SslContextBuilder, for users to directly specify
the KeyManager or TrustManager they want to use when building SslContext. This is very helpful
when users want to pass in some customized implementation of KeyManager or TrustManager.

Modification:

This PR takes the first approach in here:
https://github.com/netty/netty/issues/9767#issuecomment-551927994 (comment)
which is to immediately convert the managers into factories and let factories continue to pass
through Netty.

1. Add in SslContextBuilder the two APIs mentioned above
2. Create a KeyManagerFactoryWrapper and a TrustManagerFactoryWrapper, which take a KeyManager
and a TrustManager respectively. These are two simple wrappers that do the conversion from
XXXManager class to XXXManagerFactory class
3.Create a SimpleKeyManagerFactory class(and internally X509KeyManagerWrapper for compatibility),
which hides the unnecessary details such as KeyManagerFactorySpi. This serves the similar
functionalities with SimpleTrustManagerFactory, which was already inside Netty.

Result:

Easier usage.

920fab6e33 Improve java doc for MINIMAL_WAIT (#9779)
Motivation:

MINIMAL_WAIT is the key constant. Thus, When we see the constant, we must read more code logic to see if it is ms or ns. So improving java doc will be better.

Modifications:
Improve java doc by add "10ms" such as DEFAULT_CHECK_INTERVAL with "1s".

Result:

Easy to know it is ms and keep same java doc style with other constants such as DEFAULT_CHECK_INTERVAL.

Don't cache key material if sun.security.ssl.X509KeyManagerImpl is used (#9762)
Motivation:

sun.security.ssl.X509KeyManagerImpl will not use "stable" aliases and so aliases may be changed during invocations. This means caching is useless. Because of this we should disable the cache if its used.

Modifications:

- Disable caching if sun.security.ssl.X509KeyManagerImpl is used
- Add tests

Result:

More protection against https://github.com/netty/netty/issues/9747.

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:

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`.

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

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.

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)

No need to explicit use the AccessController when SystemPropertyUtil is used (#9577)
Motivation:

SystemPropertyUtil already uses the AccessController internally so not need to wrap its usage with AccessController as well.

Modifications:

Remove explicit AccessController usage when SystemPropertyUtil is used.

Result:

Code cleanup

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

Result:

Fixes https://github.com/netty/netty/issues/9479
