64d1eea608 Correctly pass ChannelPromise on to the next ChannelOutboundHandler when use CombinedChannelDuplexHandler.
Motivation:

Due a regression introduced by e969b6917c we missed to pass the original ChannelPromise to the next ChannelOutboundHandler and so
may never notify the origin ChannelPromise. This is related to #4805.

Modifications:

- Correctly pass the ChannelPromise
- Add unit test.

Result:

Correctly pass the ChannelPromise on deregister(...)

d5a8b65700 [#4754] Correctly detect websocket upgrade
Motivation:

If the Connection header contains multiple values (which is valid) we fail to detect a websocket upgrade

Modification:

- Add new method which allows to check if a header field contains a specific value (and also respect multiple header values)
- Use this method to detect handshake

Result:

Correct detect handshake if Connection header contains multiple values (seperated by ',').

d0b0e028d0 [#4533] Ensure replacement of decoder is delayed after finishHandshake() is called
Motivation:

If the user calls handshake.finishHandshake() we need to ensure that the user has the chance to setup the pipeline before any WebSocketFrames are read. Because of this we need
to delay the removal of the HttpRequestDecoder.

Modifications:

- Remove the HttpRequestDecoder via the EventLoop and so delay it which gives the user a chance to setup the pipeline after finishHandshake() completes
- Add unit test for this.

Result:

Less surpising and correct behaviour even if the http response and websocket frame are received in one read operation.

7e057de98b Native EPOLL Library Allows Shading
Motivation:
If Netty's class files are renamed and the type references are updated (shaded) the native libraries will not function. The native epoll module uses implicit JNI bindings which requires the fully qualified java type names to match the method signatures of the native methods. This means EPOLL cannot be used with a shaded Netty.

Modifications:
- Make the JNI method registration dynamic
- support a system property io.netty.packagePrefix which must be prepended to the name of the native library (to ensure the correct library is loaded) and all class names (to allow classes to be correctly referenced)
- remove system property io.netty.native.epoll.nettyPackagePrefix which was recently added and the code to support it was incomplete

Result:
transport-native-epoll can be used when Netty has been shaded.

4f42079627 Enable SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER when using OpenSslContext
Motivation:

We need to enable SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER when using OpenSslContext as the memory address of the buffer that is passed to OpenSslEngine.wrap(...) may change during calls and retries. This is the case as
if the buffer is a heap-buffer we will need to copy it to a direct buffer to hand it over to the JNI layer. When not enable this mode we may see errors like: 'error:1409F07F:SSL routines:SSL3_WRITE_PENDING: bad write retry'.
Related to https://github.com/netty/netty-tcnative/issues/100.

Modifications:

Explitict set mode to SSL.SSL_MODE_RELEASE_BUFFERS | SSL.SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER . (SSL.SSL_MODE_RELEASE_BUFFERS was used before implicitly).

Result:

No more 'error:1409F07F:SSL routines:SSL3_WRITE_PENDING: bad write retry' possible when writing heap buffers.

0b9ff2af3a [#4746] Support SNI when using OpenSSL
Motivation:

When using SslProvider.OPENSSL we currently not handle SNI on the client side.

Modifications:

Correctly enable SNI when using clientMode and peerHost != null.

Result:

SNI works even with SslProvider.OPENSSL.

dd2f9f9acb fix the issue netty#2944 in 4.0 #4809
Motivation:

fix the issue netty#2944

Modifications:

(1) use - instead of =>, use ! instead of :> due to the connection is bidirectional. What's more, toString() method don't know the direction or there is no need to know the direction when only log channel information.
(2) add L: before local address and R: before remote address.

Result:

after the fix, toString() won't confuse the user.

998b8a8cb9 CompositeByteBuf.addComponent always assume reference count ownership
Motivation:
The current interface for CompositeByteBuf.addComponent is not clear under what conditions ownership is transferred when addComponent is called. There should be a well defined behavior so that users can ensure that no leaks occur.

Modifications:
- CompositeByteBuf.addComponent should always assume reference count ownership

Result:
Users that call CompositeByteBuf.addComponent do not have to independently check if the buffer's ownership has been transferred and if not independently release the buffer.

7522cade65 Allow to specify tcnative artifactId and verion to allow run tests easily with different tcnative flavors
Motivation:

As we now can easily build static linked versions of tcnative it makes sense to run our netty build against all of them.
This helps to ensure our code works with libressl, openssl and boringssl.

Modifications:

Allow to specify -Dtcnative.artifactId= and -Dtcnative.version=

Result:

Easy to run netty build against different tcnative flavors.

84b9516ac5 Do not throw IndexOutOfBoundsException on an invalid SSL record
Motivation:

When an SSL record contains an invalid extension data, SniHandler
currently throws an IndexOutOfBoundsException, which is not optimal.

Modifications:

- Do strict index range checks

Result:

No more unnecessary instantiation of exceptions and their stack traces

ba381f1a27 Ensure ChannelHandler.handlerAdded(...) is always called as first method of the handler
Motivation:

If a user adds a ChannelHandler from outside the EventLoop it is possible to get into the situation that handlerAdded(...) is scheduled on the EventLoop and so called after another methods of the ChannelHandler as the EventLoop may already be executing on this point in time.

Modification:

- Ensure we always check if the handlerAdded(...) method was called already and if not add the currently needed call to the EventLoop so it will be picked up after handlerAdded(...) was called. This works as if the handler is added to the ChannelPipeline from outside the EventLoop the actual handlerAdded(...) operation is scheduled on the EventLoop.
- Some cleanup in the DefaultChannelPipeline

Result:

Correctly order of method executions of ChannelHandler.

52ba4f4ec7 Correctly handle wildcard address when bind to socket and using native transport
Motivation:

When a wildcard address is used to bind a socket and ipv4 and ipv6 are usable we should accept both (just like JDK IO/NIO does).

Modifications:

Detect wildcard address and if so use in6addr_any

Result:

Correctly accept ipv4 and ipv6

cf2e829a0e SslHandler should call beginHanshake once for the initial handshake
Motivation:
Not all SSLEngine implementations permit beginHandshake being called while a handshake is in progress during the initial handshake. We should ensure we only go through the initial handshake code once to prevent unexpected exceptions from being thrown.

Modifications:
- Only call beginHandshake if there is not currently a handshake in progress

Result:
SslHandler's handshake method is compatible with OpenSSLEngineImpl in Android 5.0+ and 6.0+.

3c254a7210 [#4722] Ensure the whole certificate chain is used when creating SslContext for client mode and SslProvider.OPENSSL is used
Motivation:

We incorrectly added the trustCertChain as certificate chain when OpenSslClientContext was created. We need to correctly add the keyCertChain.

Modifications:

Correctly add whole keyCertChain.

Result:

SSL client auth is working when usin OpenSslClientContext and more then one cert is contained in the certificate chain.

5466f68f78 Change 64 to 63 in Snappy.decodeLiteral
Motivation:

According to https://github.com/google/snappy/blob/master/format_description.txt#L55 , Snappy.decodeLiteral should handle the cases of 60, 61, 62 and 63. However right now it processes 64 instead of 63. I believe it's a typo since `tag >> 2 & 0x3F` must be less than 64.

Modifications:

Use the correct value 63.

Result:

Snappy.decodeLiteral handles the correct case.

18765a3bf7 [#4017] Implement proper resource leak detection for CompositeByteBuf
Motivation:

CompositeByteBuf only implemented simple resource leak detection and how it was implemented was completly different to the way it was for ByteBuf. The other problem was that slice(), duplicate() and others would not return a resource leak enabled buffer.

Modifications:

- Proper implementation for all level of resource leak detection for CompositeByteBuf

Result:

Proper resource leak detection for CompositeByteBuf.

d7d64137e0 Let CombinedChannelDuplexHandler correctly handle exceptionCaught. Related to [#4528]
Motivation:

ChannelInboundHandler and ChannelOutboundHandler both can implement exceptionCaught(...) method and so we need to dispatch to both of them.

Modifications:

- Correctly first dispatch exceptionCaught to the ChannelInboundHandler but also make sure the next handler it will be dispatched to will be the ChannelOutboundHandler
- Add removeInboundHandler() and removeOutboundHandler() which allows to remove one of the combined handlers

Result:

Correctly handle events

8bfbb35979 Ensure connectPromise is not notified before fireChannelActive() is called.
Motivation:

Our contract in Channels is that the promise should always be notified before the actual callbacks of the ChannelInboundHandler are called. This was not done in the LocalChannel and so the behavior was different to other Channel implementations.

Modifications:

- First complete the ChannelPromise then call fireChannelActive()
- Guard against NPE when doClose() was called before the task was executed.

Result:

Consistent behavior between LocalChannel and other Channel implementations.

53323530c1 Native Transport Netty Class Package Prefix
Motivation:
transport-native-epoll finds java classes from JNI using fully qualified class names. If a shaded version of Netty is used then these lookups will fail.

091618221a Don't enforce JZlibDecoder on JDK7+, close #4707
Motivation:

`JdkZlibDecoder` is available since Netty 4.0.8 and works with JDK7+.
However, `io.netty.noJdkZlibDecoder` System prop evaluation always defaults to
true, causing Netty to always use JZLib when decompressing on the
client side when the property insn't explictly set to `false`.

Modifications:

Default to `false` instead of `true` when JDK7+.

Result:

JZLib optional as expected on JDK7+.

27118ec53a Correctly handle non handshake commands when using SniHandler
Motivation:

As we can only handle handshake commands to parse SNI we should try to skip alert and change cipher spec commands a few times before we fallback to use a default SslContext.

Modifications:

- Use default SslContext if no application data command was received
- Use default SslContext if after 4 commands we not received a handshake command
- Simplify code
- Eliminate multiple volatile fields
- Rename SslConstants to SslUtils
- Share code between SslHandler and SniHandler by moving stuff to SslUtils

Result:

Correct handling of non handshake commands and cleaner code.

951bacb0ca Allow to change if EmbeddedChannel should handle close() and disconnect() different.
Motivation:

At the moment EmbeddedChannel always handle close() and disconnect() the same way which also means that ChannelOutboundHandler.disconnect(...) will never called. We should allow to specify if these are handle different or not to make the use of EmbeddedChannel more flexible.

Modifications:

Add 2 other constructors which allow to specify if disconnect / close are handled the same way or differently.

Result:

More flexible usage of EmbeddedChannel possible.

8fdf2f5120 Decryption failed or bad mac record in Android 5.0
Motivation:

Android 5.0 (API version 21) has a bug which not correctly set the bytesConsumed of SSLEngineResult when HandshakeStatus is FINISHED.  Because of this we need to special handle the status and so workaround the Android bug.

Modifications:

- Break the unwrap for (;;) loop when HandshakeStatus is FINISHED and bytesConsumed == 0 && bytesProduced == 0.

Result:

SslHandler works with all known version of Android.

c864c4135c Ensure we only add OpenSslEngine to the OpenSslEngineMap when handshake is started
Motivation:

We need to ensure we only add the OpenSslEngine to the OpenSslEngineMap when the handshake is started as otherwise we may produce a memory leak when the OpenSslEngine is created but not actually used. This can for example happen if we encounter a connection refused from the remote peer. In this case we will never remove the OpenSslEngine from the OpenSslEngineMap and so it will never be collected (as we hold a reference). This has as affect that the finalizer will never be run as well.

Modifications:

- Lazy add the OpenSslEngine to the OpenSslEngineMap to elimate possible leak.
- Call OpenSslEngine.shutdown() when SslHandler is removed from the ChannelPipeline to free memory asap in all cases.

Result:

No more memory leak with OpenSslEngine if connection is refused.

- Use jetty-alpn-agent, which chooses the correct alpn-boot.jar and
  npn-boot.jar automatically to remove all the nasty profile sections
  from pom.xml
  - Visit https://github.com/trustin/jetty-alpn-agent for more info
