eb1d9da76c 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.

e220c56823 [#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.

7090d1331c Clear disabled SSL protocols before enabling provided SSL protocols
Motivation:

Attempts to enable SSL protocols which are currently disabled fail when using the OpenSslEngine. Related to https://github.com/netty/netty/issues/4736

Modifications:

Clear out all options that have disabled SSL protocols before attempting to enable any SSL protocol.

Result:

setEnabledProtocols works as expected.

8732745264 OpenSslEngine skip ALPN tests if OpenSsl version doesn't support ALPN
Motivation:
OpenSslEngine now tests ALPN behavior. However it is possible that OpenSSL is present, but the version does not support ALPN. This will result in test failures instead of just skipping the test.

Modifications:
- Skip ALPN tests in OpenSslEngineTest if the version of OpenSSL does not support ALPN

Result:
Tests don't fail due to unsupported feature in OpenSSL.

ba22b0b944 Implement OpenSSL Engine tests for NPN / ALPN.
Motivation:

Currently there are no tests for OpenSSL Engine,
only for JdkSSL engine.

Modifications:

Common methods from `JdkSslEngine` test moved
to `SSLEngineTest`, JdkSslEngine now implements
NPN and ALPN tests.

Result:

OpenSSL Engine is now covered with unit tests.

fd5316ed6f ChunkedInput.readChunk parameter of type ByteBufAllocator
Motivation:
ChunkedInput.readChunk currently takes a ChannelHandlerContext object as a parameters. All current implementations of this interface only use this object to get the ByteBufAllocator object. Thus taking a ChannelHandlerContext as a parameter is more restrictive for users of this API than necessary.

Modifications:
- Add a new method readChunk(ByteBufAllocator)
- Deprecate readChunk(ChannelHandlerContext) and updates all implementations to call readChunk(ByteBufAllocator)

Result:
API that only requires ByteBufAllocator to use ChunkedInput.

43ebbc3fa0 Update JDK SSL Tests to use SSL Context Builder.
Motivation:

Use new / non-deprecated APIs for creating SSL Context
in tests, in order to be able to implement OpenSsl
tests with maximum code reuse.

Modifications:

Use `SslContextBuilder.(forServer|forClient)` instead
of deprecated `JdkSslServerContext` constructor.
Use `ApplicationProtocolConfig` instead of Protocol
Negotiator.
Use custom exception type for skipping tests to avoid
swallowing exceptions arising from tests.

Result:

Exceptions from tests aren't swallowed.
Using new APIs allows reusing same test code for
OpenSsl tests.

4aa19a09bd Implement SSLSession.invalidate() and isValid() for OpenSSLEngine.
Motivation:

The SSLSession allows to invalidate a SSLSession and so disallow resume of a session. We should support this for OpenSSLEngine as well.

Modifications:

- Correctly implement SSLSession.isValid() and invalidate() in OpenSSLEngine
- Add unit test.

Result:

Invalidate of SSL sessions is supported when using OpenSSL now.

5deec9631f Add support for server-side renegotiation when using OpenSslEngine.
Motivation:

JDK SslEngine supports renegotion, so we should at least support it server-side with OpenSslEngine as well.

That said OpenSsl does not support sending messages asynchronly while the renegotiation is still in progress, so the application need to ensure there are not writes going on while the renegotiation takes place. See also https://rt.openssl.org/Ticket/Display.html?id=1019 .

Modifications:

- Add support for renegotiation when OpenSslEngine is used in server mode
- Add unit tests.
- Upgrade to netty-tcnative 1.1.33.Fork9

Result:

Better compatibility with the JDK SSLEngine implementation.

a1d0207ec5 Adding client auth to SslContextBuilder
Motivation:

To simplify the use of client auth, we need to add it to the SslContextBuilder.

Modifications:

Added a ClientAuth enum and plumbed it through the builder, down into the contexts/engines.

Result:

Client auth can be configured when building an SslContext.

5ac84760c4 Allow to create SslContext from existing PrivateKey / X509Certificate
Motivation:

Sometimes the user already has a PrivateKey / X509Certificate which should be used to create a new SslContext. At the moment we only allow to construct it via Files.

Modifications:

- Add new methods to the SslContextBuilder to allow creating a SslContext from PrivateKey / X509Certificate
- Mark all public constructors of *SslContext as @Deprecated, the user should use SslContextBuilder
- Update tests to us SslContextBuilder.

Result:

Creating of SslContext is possible with PrivateKay/X509Certificate

ecc01da9dd [#3968] Disallow pass-through of non ByteBufs in SslHandler
Motivation:

We pass-through non ByteBuf when SslHandler.write(...) is called which can lead to have unencrypted data to be send (like for example if a FileRegion is written).

Modifications:

- Fail ChannelPromise with UnsupportedMessageException if a non ByteBuf is written.

Result:

Only allow ByteBuf to be written when using SslHandler.

afb46b926f Improve the API design of Http2OrHttpChooser and SpdyOrHttpChooser
Related: #3641 and #3813

Motivation:

When setting up an HTTP/1 or HTTP/2 (or SPDY) pipeline, a user usually
ends up with adding arbitrary set of handlers.

Http2OrHttpChooser and SpdyOrHttpChooser have two abstract methods
(create*Handler()) that expect a user to return a single handler, and
also have add*Handlers() methods that add the handler returned by
create*Handler() to the pipeline as well as the pre-defined set of
handlers.

The problem is, some users (read: I) don't need all of them or the
user wants to add more than one handler. For example, take a look at
io.netty.example.http2.tiles.Http2OrHttpHandler, which works around
this issue by overriding addHttp2Handlers() and making
createHttp2RequestHandler() a no-op.

Modifications:

- Replace add*Handlers() and create*Handler() with configure*()
- Rename getProtocol() to selectProtocol() to make what it does clear
- Provide the default implementation of selectProtocol()
- Remove SelectedProtocol.UNKNOWN and use null instead, because
  'UNKNOWN' is not a protocol
- Proper exception handling in the *OrHttpChooser so that the
  exception is logged and the connection is closed when failed to
  select a protocol
- Make SpdyClient example always use SSL. It was always using SSL
  anyway.
- Implement SslHandshakeCompletionEvent.toString() for debuggability
- Remove an orphaned class: JettyNpnSslSession
- Add SslHandler.applicationProtocol() to get the name of the
  application protocol
  - SSLSession.getProtocol() now returns transport-layer protocol name
    only, so that it conforms to its contract.

Result:

- *OrHttpChooser have better API.
- *OrHttpChooser handle protocol selection failure properly.
- SSLSession.getProtocol() now conforms to its contract.
- SpdyClient example works with SpdyServer example out of the box

- Correctly throw SSLHandshakeException when an error during handshake is detected

Result:

Mutual auth can be used with OpenSslEngine

44eeb5f6b4 Fix intermittent test failure in LoggingHandlerTest
Motivation:

LoggingHandlerTest sometimes failure due to unexpected log messages
logged due to the automatic reclaimation of thread-local objects.

  Expectation failure on verify:
    Appender.doAppend([DEBUG] Freed 3 thread-local buffer(s) from thread: nioEventLoopGroup-23-0): expected: 1, actual: 0
    Appender.doAppend([DEBUG] Freed 9 thread-local buffer(s) from thread: nioEventLoopGroup-23-1): expected: 1, actual: 0
    Appender.doAppend([DEBUG] Freed 2 thread-local buffer(s) from thread: nioEventLoopGroup-23-2): expected: 1, actual: 0
    Appender.doAppend([DEBUG] Freed 4 thread-local buffer(s) from thread: nioEventLoopGroup-26-0): expected: 1, actual: 0
    Appender.doAppend(matchesLog(expected: ".+CLOSE$", got: "[id: 0xembedded, embedded => embedded] CLOSE")): expected: 1, actual: 0

Modifications:

Add the mock appender to the related logger only

Result:

No more intermittent test failures

a97e413a65 Ensure server preference order in ALPN
Motivation:
With the current implementation the client protocol preference list
takes precedence over the one of the server, since the select method
will return the first item, in the client list, that matches any of the
protocols supported by the server. This violates the recommendation of
http://tools.ietf.org/html/rfc7301#section-3.2.

It will also fail with the current implementation of Chrome, which
sends back Extension application_layer_protocol_negotiation, protocols:
[http/1.1, spdy/3.1, h2-14]

Modifications:
Changed the protocol negotiator to prefer server’s list. Added a test
case that demonstrates the issue and that is fixed with the
modifications of this commit.

Result:
Server’s preference list is used.

7d50f7864c Implement OpenSslEngine.getSupportedCipherSuites() and get/setEnabledCipherSuites()
Motivation:

To make OpenSslEngine a full drop-in replacement, we need to implement
getSupportedCipherSuites() and get/setEnabledCipherSuites().

Modifications:

- Retrieve the list of the available cipher suites when initializing
  OpenSsl.
- Improve CipherSuiteConverter to understand SRP
- Add more test data to CipherSuiteConverterTest
- Add bulk-conversion method to CipherSuiteConverter

Result:

OpenSslEngine should now be a drop-in replacement for JDK SSLEngineImpl
for most cases.

a093f00b67 Cipher suite conversion between Java and OpenSSL
Related: #3285

Motivation:

When a user attempts to switch from JdkSslContext to OpenSslContext, he
or she will see the initialization failure if he or she specified custom
cipher suites.

Modifications:

- Provide a utility class that converts between Java cipher suite string
  and OpenSSL cipher suite string
- Attempt to convert the cipher suite so that a user can use the cipher
  suite string format of Java regardless of the chosen SslContext impl

Result:

- It is possible to convert all known cipher suite strings.
- It is possible to switch from JdkSslContext and OpenSslContext and
  vice versa without any configuration changes

8f77c80795 Added support for SSL Server Name Indication.
Motivation:

When we need to host multiple server name with a single IP, it requires
the server to support Server Name Indication extension to serve clients
with proper certificate. So the SniHandler will host multiple
SslContext(s) and append SslHandler for requested hostname.

Modification:

* Added SniHandler to host multiple certifications in a single server
* Test case

Result:

User could use SniHandler to host multiple certifcates at a time.
It's server-side only.

35db3c6710 Small performance improvements
Motivation:

Found performance issues via FindBugs and PMD.

Modifications:

- Removed unnecessary boxing/unboxing operations in DefaultTextHeaders.convertToInt(CharSequence) and DefaultTextHeaders.convertToLong(CharSequence). A boxed primitive is created from a string, just to extract the unboxed primitive value.
- Added a static modifier for DefaultHttp2Connection.ParentChangedEvent class. This class is an inner class, but does not use its embedded reference to the object which created it. This reference makes the instances of the class larger, and may keep the reference to the creator object alive longer than necessary.
- Added a static compiled Pattern to avoid compile it each time it is used when we need to replace some part of authority.
- Improved using of StringBuilders.

Result:

Performance improvements.

b285994e10 Support IPv4 default route in ipfilter.
Motivation:

In GitHub issue #2767 a bug was reported that the IPv4
default route leads to the ipfilter package denying
instead of accepting all addresses.

While the issue was reported for Netty 3.9, this bug
also applies to Netty 4 and higher.

Modifications:

When computing the subnet address from the CIDR prefix,
correctly handle the case where the prefix is set to zero.

Result:

Ipfilter accepts all addresses when passed the
IPv4 default route.

ca29be5e77 Allow ChunkedInput to provide the progress of its transfer
Related issue: #2741 and #2151

Motivation:

There is no way for ChunkedWriteHandler to know the progress of the
transfer of a ChannelInput. Therefore, ChannelProgressiveFutureListener
cannot get exact information about the progress of the transfer.

If you add a few methods that optionally provides the transfer progress
to ChannelInput, it becomes possible for ChunkedWriteHandler to notify
ChannelProgressiveFutureListeners.

If the input has no definite length, we can still use the progress so
far, and consider the length of the input as 'undefined'.

Modifications:

- Add ChunkedInput.progress() and ChunkedInput.length()
- Modify ChunkedWriteHandler to use progress() and length() to notify
  the transfer progress

Result:

ChunkedWriteHandler now notifies ChannelProgressiveFutureListener.

20dffa8ee6 [#2718] Added private key decryption to JDK SSL server context.
Motivation:

Currently it is not possible to load an encrypted private key when
creating a JDK based SSL server context.

Modifications:

- Added static method to JdkSslServerContext which handles key spec generation for (encrypted) private keys and make use of it.
-Added tests for creating a SSL server context based on a (encrypted)
private key.

Result:

It is now possible to create a JDK based SSL server context with an
encrypted (password protected) private key.

cf275237c9 Overall clean-up of ipfilter package
Motivation:

Recently merged ipfilter package has the following problems:
* AbstractIpFilterHandler could be improved to support any SocketAddress types rather than only InetSocketAddress.
* AbstractIpFilterHandler can be removed immediately after decision is made rather than keeping the outcome of the decision as an attribute.
* AbstractIpFilterHandler doesn't have a hook for the accepted addresses.
* The hook method (reject()) needs to be named in line with other handler methods (i.e. channelRejected())
* IpFilterRuleHandler should allow accepting zero rules - it's particularly useful for machine-configured setup (i.e. specifying zero rules disables ipfilter).
* IpFilterRuleType.ALLOW/DENY should be ACCEPT/REJECT for consistency.

Modifications:

* AbstractIpFilterHandler has been renamed to AbstractRemoteAddressFilter and now uses type parameter.
* Added channelAccepted() and renamed reject() to channelRejected()
* Added ChannelHandlerContext as a parameter of accept() so that accept() can add a listener to the closeFuture() of the channel. This way, UniqueIpFilter continue working even if we remove the filtering handler early.
* Various renames
  * IpFilterRuleHandler -> RuleBasedIpFilter
  * UniqueIpFilterHandler -> UniqueIpFilter

Result:

* Much cleaner API with more extensibility

835b4443f3 Optimize and clean up LoggingHandler
- Use ': ' instead of '(...)' for simpler string concatenation and prettier presentation
- Optimize the overall performance of format*() methods
- All format*() methods are now expected to encode the channel information by themselves so that StringBuilder instances are created less often.
- Use a look-up table for generating per-row prefixes
- Hid formatByteBuf(), formatByteBufHolder(), and formatNonByteBuf() from user because a user can always override format(ctx, eventName, arg).  For example, to disable hexdump:

    protected void format(ChannelHandlerContext ctx, String eventName, Object arg) {
        if (arg instanceof ByteBuf) {

cbd8817905 Remove MessageList from public API and change ChannelInbound/OutboundHandler accordingly
I must admit MesageList was pain in the ass.  Instead of forcing a
handler always loop over the list of messages, this commit splits
messageReceived(ctx, list) into two event handlers:

- messageReceived(ctx, msg)
- mmessageReceivedLast(ctx)

When Netty reads one or more messages, messageReceived(ctx, msg) event
is triggered for each message.  Once the current read operation is
finished, messageReceivedLast() is triggered to tell the handler that
the last messageReceived() was the last message in the current batch.

Similarly, for outbound, write(ctx, list) has been split into two:

- write(ctx, msg)
- flush(ctx, promise)

Instead of writing a list of message with a promise, a user is now
supposed to call write(msg) multiple times and then call flush() to
actually flush the buffered messages.

Please note that write() doesn't have a promise with it.  You must call
flush() to get notified on completion. (or you can use writeAndFlush())

Other changes:

- Because MessageList is completely hidden, codec framework uses
  List<Object> instead of MessageList as an output parameter.

14158070bf Revamp the core API to reduce memory footprint and consumption
The API changes made so far turned out to increase the memory footprint
and consumption while our intention was actually decreasing them.

Memory consumption issue:

When there are many connections which does not exchange data frequently,
the old Netty 4 API spent a lot more memory than 3 because it always
allocates per-handler buffer for each connection unless otherwise
explicitly stated by a user.  In a usual real world load, a client
doesn't always send requests without pausing, so the idea of having a
buffer whose life cycle if bound to the life cycle of a connection
didn't work as expected.

Memory footprint issue:

The old Netty 4 API decreased overall memory footprint by a great deal
in many cases.  It was mainly because the old Netty 4 API did not
allocate a new buffer and event object for each read.  Instead, it
created a new buffer for each handler in a pipeline.  This works pretty
well as long as the number of handlers in a pipeline is only a few.
However, for a highly modular application with many handlers which
handles connections which lasts for relatively short period, it actually
makes the memory footprint issue much worse.

Changes:

All in all, this is about retaining all the good changes we made in 4 so
far such as better thread model and going back to the way how we dealt
with message events in 3.

To fix the memory consumption/footprint issue mentioned above, we made a
hard decision to break the backward compatibility again with the
following changes:

- Remove MessageBuf
- Merge Buf into ByteBuf
- Merge ChannelInboundByte/MessageHandler and ChannelStateHandler into ChannelInboundHandler
  - Similar changes were made to the adapter classes
- Merge ChannelOutboundByte/MessageHandler and ChannelOperationHandler into ChannelOutboundHandler
  - Similar changes were made to the adapter classes
- Introduce MessageList which is similar to `MessageEvent` in Netty 3
- Replace inboundBufferUpdated(ctx) with messageReceived(ctx, MessageList)
- Replace flush(ctx, promise) with write(ctx, MessageList, promise)
- Remove ByteToByteEncoder/Decoder/Codec
  - Replaced by MessageToByteEncoder<ByteBuf>, ByteToMessageDecoder<ByteBuf>, and ByteMessageCodec<ByteBuf>
- Merge EmbeddedByteChannel and EmbeddedMessageChannel into EmbeddedChannel
- Add SimpleChannelInboundHandler which is sometimes more useful than
  ChannelInboundHandlerAdapter
- Bring back Channel.isWritable() from Netty 3
- Add ChannelInboundHandler.channelWritabilityChanges() event
- Add RecvByteBufAllocator configuration property
  - Similar to ReceiveBufferSizePredictor in Netty 3
  - Some existing configuration properties such as
    DatagramChannelConfig.receivePacketSize is gone now.
- Remove suspend/resumeIntermediaryDeallocation() in ByteBuf

This change would have been impossible without @normanmaurer's help. He
fixed, ported, and improved many parts of the changes.
