e72b2235fb Make sure to notify handshake success even if SSLEngine is closed
Related:

e9685ea45a

Motivation:

SslHandler.unwrap() does not evaluate the handshake status of
SSLEngine.unwrap() when the status of SSLEngine.unwrap() is CLOSED.

It is not correct because the status does not reflect the state of the
handshake currently in progress, accoding to the API documentation of
SSLEngineResult.Status.

Also, sslCloseFuture can be notified earlier than handshake notification
because we call sslCloseFuture.trySuccess() before evaluating handshake
status.

Modifications:

- Notify sslCloseFuture after the unwrap loop is finished
- Add more assertions to SocketSslEchoTest

Result:

Potentially fix the regression caused by:

d5a24d4f6c Make SslHandler work when autoRead is turned off
Related: #2958

Motivation:

SslHandler currently does not issue a read() request when it is
handshaking. It makes a connection with autoRead off stall, because a
user's read() request can be used to read the handshake response which
is invisible to the user.

Modifications:

- SslHandler now issues a read() request when:
  - the current handshake is in progress and channelReadComplete() is
    invoked
  - the current handshake is complete and a user issued a read() request
    during handshake
- Rename flushedBeforeHandshakeDone to flushedBeforeHandshake for
  consistency with the new variable 'readDuringHandshake'

Result:

SslHandler should work regardless whether autoRead is on or off.

1dc1831abf Add SslHandler.renegotiate()
Related: #3125

Motivation:

We did not expose a way to initiate TLS renegotiation and to get
notified when the renegotiation is done.

Modifications:

- Add SslHandler.renegotiate() so that a user can initiate TLS
  renegotiation and get the future that's notified on completion
- Make SslHandler.handshakeFuture() return the future for the most
  recent handshake so that a user can get the future of the last
  renegotiation
- Add the test for renegotiation to SocketSslEchoTest

Result:

Both client-initiated and server-initiated renegotiations are now
supported properly.

9ff234abed Call ctx.flush() at least once in ChunkedWriteHandler.flush()
Related: #3219

Motivation:

ChunkedWriteHandler.flush() does not call ctx.flush() when channel is
not writable. This can be a problem when other handler / non-Netty
thread writes messages simultaneously, because
ChunkedWriteHandler.flush() might have no chance to observe
channel.isWritable() returns true and thus the channel is never flushed.

Modifications:

- Ensure that ChunkedWriteHandler.flush() calls ctx.flush() at least
  once.

Result:

A stall connection issue, that occurs when certain combination of
handlers exist in a pipeline, has been fixed. (e.g. SslHandler and
ChunkedWriteHandler)

96d596802b Fix dependency issues with hamcrest
Motivation:

We use 3 (!) libraries to build mock objects - easymock, mockito, jmock.
Mockito and jMock pulls in the different versions of Hamcrest, and it
conflicts with the version pulled by jUnit.

Modifications:

- Replace mockito-all with mockito-core to avoid pulling in outdated
  jUnit and Hamcrest
- Exclude junit-dep when pulling in jmock-junit4, because it pulls an
  outdated Hamcrest version
- Pull in the hamcrest-library version used by jUnit explicitly

Result:

No more dependency hell that results in NoSuchMethodError during the
tests

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.

d33a80da26 Use Triple DES in JdkSslContext cipher suite list.
Motivation:

JdkSslContext used SSL_RSA_WITH_DES_CBC_SHA in its cipher suite list.
OpenSslServerContext used DES-CBC3-SHA in the same place in its cipher suite
list, which is equivalent to SSL_RSA_WITH_3DES_EDE_CBC_SHA.

This means the lists were out of sync. Furthermore, using
SSL_RSA_WITH_DES_CBC_SHA is not desirable as it uses DES, a weak cipher. Triple
DES should be used instead.

Modifications:

Replace SSL_RSA_WITH_DES_CBC_SHA with SSL_RSA_WITH_3DES_EDE_CBC_SHA in
JdkSslContext.

Result:

The JdkSslContext and OpenSslServerContext cipher suite lists are now in sync.
Triple DES is used instead of DES, which is stronger.

Motivation:

RC4 is not a recommended cipher suite anymore, as the recent research
reveals, such as:

- http://www.isg.rhul.ac.uk/tls/

Modifications:

- Remove most RC4 cipher suites from the default cipher suites
- For backward compatibility, leave RC4-SHA, while de-prioritizing it

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.

f2678a31ff Add ApplicationProtocolConfig.DISABLED
Motivation:

When ALPN/NPN is disabled, a user has to instantiate a new
ApplicationProtocolConfig with meaningless parameters.

Modifications:

- Add ApplicationProtocolConfig.DISABLED, the singleton instance
- Reject the constructor calls with Protocol.NONE, which doesn't make
  much sense because a user should use DISABLED instead.

Result:

More user-friendly API when ALPN/NPN is not needed by a user.

Motivation:

Previous backport removed the old methods and constructors. They should
not be removed in 4.x but just deprecated in favor of the new methods
and constructors.

Modifications:

746c8cab32 SslHander wrap conditional direct buffer allocation
Motivation:
The SslHandler currently forces the use of a direct buffer for the input to the SSLEngine.wrap(..) operation. This allocation may not always be desired and should be conditionally done.

Modifications:
- Use the pre-existing wantsDirectBuffer variable as the condition to do the conversion.

Result:
- An allocation of a direct byte buffer and a copy of data is now not required for every SslHandler wrap operation.

06ea226a28 SslHandler wrap memory leak
Motivation:
The SslHandler wrap method requires that a direct buffer be passed to the SSLEngine.wrap() call. If the ByteBuf parameter does not have an underlying direct buffer then one is allocated in this method, but it is not released.

Modifications:
- Release the direct ByteBuffer only accessible in the scope of SslHandler.wrap

Result:
Memory leak in SslHandler.wrap is fixed.

57f48e0ec8 Fixed FingerprintTrustManagerFactory constructor
Motivation:

When constructing a FingerprintTrustManagerFactory from an Iterable of Strings, the fingerprints were correctly parsed but never added to the result array. The constructed FingerprintTrustManagerFactory consequently fails to validate any certificate.

Modifications:

I added a line to add each converted SHA-1 certificate fingerprint to the result array which then gets passed on to the next constructor.

Result:

Certificate fingerprints passed to the constructor are now correctly added to the array of valid fingerprints. The resulting FingerprintTrustManagerFactory object correctly validates certificates against the list of specified fingerprints.

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.

bc1379d19d [#2721] Improve Traffic Shaping handler
Motivation:
Currently Traffic Shaping is using 1 timer only and could lead to
"partial" wrong bandwidth computation when "short" time occurs between
adding used bytes and when the TrafficCounter updates itself and finally
when the traffic is computed.
Indeed, the TrafficCounter is updated every x delay and it is at the
same time saved into "lastXxxxBytes" and set to 0. Therefore, when one
request the counter, it first updates the TrafficCounter with the added
used bytes. If this value is set just before the TrafficCounter is
updated, then the bandwidth computation will use the TrafficCounter with
a "0" value (this value being reset once the delay occurs). Therefore,
the traffic shaping computation is wrong in rare cases.

Secondly the traffic shapping should avoid if possible the "Timeout"
effect by not stopping reading or writing more than a maxTime, this
maxTime being less than the TimeOut limit.

Thirdly the traffic shapping in read had an issue since the readOp
was not set but should, turning in no read blocking from socket
point of view.

Modifications:
The TrafficCounter has 2 new methods that compute the time to wait
according to read or write) using in priority the currentXxxxBytes (as
before), but could used (if current is at 0) the lastXxxxxBytes, and
therefore having more chance to take into account the real traffic.

Moreover the Handler could change the default "max time to wait", which
is by default set to half of "standard" Time Out (30s:2 = 15s).

Finally we add the setAutoRead(boolean) accordingly to the situation,
as proposed in #2696 (this pull request is in error for unknown reason).

Result:
The Traffic Shaping is better take into account (no 0 value when it
shouldn't) and it tries to not block traffic more than Time Out event.

Moreover the read is really stopped from socket point of view.

This version is similar to #2388 and #2450.
This version is for V4.1, and includes the #2696 pull request
to ease the merge process.
It is compatible with master too.

Including also #2748

The test minimizes time check by reducing to 66ms steps (55s).

02e7e53cbb [#2752] Add PendingWriteQueue for queue up writes
Motivation:

Sometimes ChannelHandler need to queue writes to some point and then process these. We currently have no datastructure for this so the user will use an Queue or something like this. The problem is with this Channel.isWritable() will not work as expected and so the user risk to write to fast. That's exactly what happened in our SslHandler. For this purpose we need to add a special datastructure which will also take care of update the Channel and so be sure that Channel.isWritable() works as expected.

Modifications:

- Add PendingWriteQueue which can be used for this purpose
- Make use of PendingWriteQueue in SslHandler

Result:

It is now possible to queue writes in a ChannelHandler and still have Channel.isWritable() working as expected. This also fixes #2752.

Result:

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

c85319213a [#2675] Replace synchronization performed on util.concurrent instance in TrafficCounter
Motivation:

Message from FindBugs:
This method performs synchronization an object that is an instance of a class from the java.util.concurrent package (or its subclasses). Instances of these classes have their own concurrency control mechanisms that are orthogonal to the synchronization provided by the Java keyword synchronized. For example, synchronizing on an AtomicBoolean will not prevent other threads from modifying the AtomicBoolean.
Such code may be correct, but should be carefully reviewed and documented, and may confuse people who have to maintain the code at a later date.

Modification:

Use synchronized(this)

Result:

Less confusing code

b83df4c6b3 Fix NPE problems
Motivation:

Now Netty has a few problems with null values.

Modifications:

- Check HAProxyProxiedProtocol in HAProxyMessage constructor and throw NPE if it is null.
If HAProxyProxiedProtocol is null we will set AddressFamily as null. So we will get NPE inside checkAddress(String, AddressFamily) and it won't be easy to understand why addrFamily is null.
- Check File in DiskFileUpload.toString().
If File is null we will get NPE when calling toString() method.
- Check Result<String> in MqttDecoder.decodeConnectionPayload(...).
If !mqttConnectVariableHeader.isWillFlag() || !mqttConnectVariableHeader.hasUserName() || !mqttConnectVariableHeader.hasPassword() we will get NPE when we will try to create new instance of MqttConnectPayload.
- Check Unsafe before calling unsafe.getClass() in PlatformDependent0 static block.
- Removed unnecessary null check in WebSocket08FrameEncoder.encode(...).
Because msg.content() can not return null.
- Removed unnecessary null check in DefaultStompFrame(StompCommand) constructor.
Because we have this check in the super class.
- Removed unnecessary null checks in ConcurrentHashMapV8.removeTreeNode(TreeNode<K,V>).
- Removed unnecessary null check in OioDatagramChannel.doReadMessages(List<Object>).
Because tmpPacket.getSocketAddress() always returns new SocketAddress instance.
- Removed unnecessary null check in OioServerSocketChannel.doReadMessages(List<Object>).
Because socket.accept() always returns new Socket instance.
- Pass Unpooled.buffer(0) instead of null inside CloseWebSocketFrame(boolean, int) constructor.
If we will pass null we will get NPE in super class constructor.
- Added throw new IllegalStateException in GlobalEventExecutor.awaitInactivity(long, TimeUnit) if it will be called before GlobalEventExecutor.execute(Runnable).
Because now we will get NPE. IllegalStateException will be better in this case.
- Fixed null check in OpenSslServerContext.setTicketKeys(byte[]).
Now we throw new NPE if byte[] is not null.

Result:

Added new null checks when it is necessary, removed unnecessary null checks and fixed some NPE problems.

217fb0de05 [#2618] Introduce ChannelPromise.unvoid() and ChannelFuture.isVoid()
Motivation:

There is no way for a ChannelHandler to check if the passed in ChannelPromise for a write(...) call is a VoidChannelPromise. This is a problem as some handlers need to add listeners to the ChannelPromise which is not possible in the case of a VoidChannelPromise.

Modification:

- Introduce ChannelFuture.isVoid() which will return true if it is not possible to add listeners or wait on the result.
- Add ChannelPromise.unvoid() which allows to create a ChannelFuture out of a void ChannelFuture which supports all the operations.

Result:

It's now easy to write ChannelHandler implementations which also works when a void ChannelPromise is used.

085a61a310 Refactor FastThreadLocal to simplify TLV management
Motivation:

When Netty runs in a managed environment such as web application server,
Netty needs to provide an explicit way to remove the thread-local
variables it created to prevent class loader leaks.

FastThreadLocal uses different execution paths for storing a
thread-local variable depending on the type of the current thread.
It increases the complexity of thread-local removal.

Modifications:

- Moved FastThreadLocal and FastThreadLocalThread out of the internal
  package so that a user can use it.
- FastThreadLocal now keeps track of all thread local variables it has
  initialized, and calling FastThreadLocal.removeAll() will remove all
  thread-local variables of the caller thread.
- Added FastThreadLocal.size() for diagnostics and tests
- Introduce InternalThreadLocalMap which is a mixture of hard-wired
  thread local variable fields and extensible indexed variables
- FastThreadLocal now uses InternalThreadLocalMap to implement a
  thread-local variable.
- Added ThreadDeathWatcher.unwatch() so that PooledByteBufAllocator
  tells it to stop watching when its thread-local cache has been freed
  by FastThreadLocal.removeAll().
- Added FastThreadLocalTest to ensure that removeAll() works
- Added microbenchmark for FastThreadLocal and JDK ThreadLocal
- Upgraded to JMH 0.9

Result:

- A user can remove all thread-local variables Netty created, as long as
  he or she did not exit from the current thread. (Note that there's no
  way to remove a thread-local variable from outside of the thread.)
- FastThreadLocal exposes more useful operations such as isSet() because
  we always implement a thread local variable via InternalThreadLocalMap
  instead of falling back to JDK ThreadLocal.
- FastThreadLocalBenchmark shows that this change improves the
  performance of FastThreadLocal even more.

861ed1e7ad Add unified NextProtoNego extension support to SslContext
Motivation:

- OpenSslEngine and JDK SSLEngine (+ Jetty NPN) have different APIs to
  support NextProtoNego extension.
  - It is impossible to configure NPN with SslContext when the provider
    type is JDK.

Modification:

- Implement NextProtoNego extension by overriding the behavior of
  SSLSession.getProtocol() for both OpenSSLEngine and JDK SSLEngine.
  - SSLEngine.getProtocol() returns a string delimited by a colon (':')
    where the first component is the transport protosol (e.g. TLSv1.2)
    and the second component is the name of the application protocol
- Remove the direct reference of Jetty NPN classes from the examples
- Add SslContext.newApplicationProtocolSelector

Result:

- A user can now use both JDK SSLEngine and OpenSslEngine for NPN-based
  protocols such as HTTP2 and SPDY

ae61b12b9e Reduce memory usage of SslHandler when OpenSslEngine is in use
Motivation:

JDK's SSLEngine.wrap() requires the output buffer to be always as large as MAX_ENCRYPTED_PACKET_LENGTH even if the input buffer contains small number of bytes.  Our OpenSslEngine implementation does not have such wasteful behaviot.

Modifications:

If the current SSLEngine is OpenSslEngine, allocate as much as only needed.

Result:

Less peak memory usage.
