62057f73d6 Fix handling of non-auto read for ByteToMessageDecoder and SslHandler
Motivation:

Our automatically handling of non-auto-read failed because it not detected the need of calling read again by itself if nothing was decoded. Beside this handling of non-auto-read never worked for SslHandler as it always triggered a read even if it decoded a message and auto-read was false.

This fixes [#3529] and [#3587].

Modifications:

- Implement handling of calling read when nothing was decoded (with non-auto-read) to ByteToMessageDecoder again
- Correctly respect non-auto-read by SslHandler

Result:

No more stales and correctly respecting of non-auto-read by SslHandler.

bdfdf3094d Reduce object allocation during wrap/unwrap while handshake is in progress
Motivation:

Unnecessary object allocation is currently done during wrap/unwrap while a handshake is still in progress.

Modifications:

Use static instances when possible.

Result:

Less object creations.

3850cff0fc Allow to get version of available OpenSSL library
Motivation:

Sometimes it's useful to get informations about the available OpenSSL library that is used for the OpenSslEngine.

Modifications:

Add two new methods which allows to get the available OpenSSL version as either
an int or an String.

Result:

Easy to access details about OpenSSL version.

4e70523edd The "null" ClassLoader is the bootstrap ClassLoader
Motivation:
Class.forName() documents that null will use bootstrap loader:
http://docs.oracle.com/javase/8/docs/api/java/lang/Class.html#forName-java.lang.String-boolean-java.lang.ClassLoader-

But the link between "null" and bootstrap loader is even more explicit
in ClassLoader's documentation:
http://docs.oracle.com/javase/8/docs/api/java/lang/ClassLoader.html#getParent--

The current code is trying to use the bootstrap loader but seems to have
not been aware of the meaning of null.

Modifications:
Use "null" as the class loader when we want to load classes in the
bootstrap loader.

Result:
More reliable ALPN/NPN loading and simpler code.

6c3f5ab34d Add support for EC Keys when using SslServerContext
Motivation:

Sometimes it's useful to use EC keys and not DSA or RSA. We should support it.

Modifications:

bd224286f5 [#3531] Create SslContext.Builder
Motivation:

SslContext factory methods have gotten out of control; it's past time to
swap to a builder.

Modifications:

aebbb862ac Add support for ALPN when using openssl + NPN client mode and support for CipherSuiteFilter
Motivation:

To support HTTP2 we need APLN support. This was not provided before when using OpenSslEngine, so SSLEngine (JDK one) was the only bet.
Beside this CipherSuiteFilter was not supported

Modifications:

- Upgrade netty-tcnative and make use of new features to support ALPN and NPN in server and client mode.
- Guard against segfaults after the ssl pointer is freed
- support correctly different failure behaviours
- add support for CipherSuiteFilter

Result:

Be able to use OpenSslEngine for ALPN / NPN for server and client.

190cbf55e4 Fix incorrect null value check in TrafficCounter
In TrafficCounter, a recent change makes the contract of the API (the
constructor) wrong and lead to issue with GlobalChannelTrafficCounter
where executor must be null.

Motivation:
TrafficCounter executor argument in constructor might be null, as
explained in the API, for some particular cases where no executor are
needed (relevant tasks being taken by the caller as in
GlobalChannelTrafficCounter).
A null pointer exception is raised while it should not since it is
legal.

Modifications:
Remove the 2 null checking for this particular attribute.
Note that when null, the attribute is not reached nor used (a null
checking condition later on is applied).

Result:
No more null exception raized while it should not.

This shall be made also to 4.0, 4.1 (present) and master. 3.10 is not
concerned.

2e509f7bb7 Fix unbounded expansion of cumulative buffer in SslHandler
Related: #3567

Motivation:

SslHandler.channelReadComplete() forgets to call
super.channelReadComplete(), which discards read bytes from the
cumulative buffer.  As a result, the cumulative buffer can expand its
capacity unboundedly.

Modifications:

Call super.channelReadComplete() instead of calling
ctx.fireChannelReadComplete()

Result:

Fixes #3567

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:

f4e527c64d Don't trigger IOException at ChunkedStream.isEndOfInput()
Related: #3368

Motivation:

ChunkedWriteHandler checks if the return value of
ChunkedInput.isEndOfInput() after calling ChunkedInput.close().

This makes ChunkedStream.isEndOfInput() trigger an IOException, which is
originally triggered by PushBackInputStream.read().

By contract, ChunkedInput.isEndOfInput() should not raise an IOException
even when the underlying stream is closed.

Modifications:

Add a boolean flag that keeps track of whether the underlying stream has
been closed or not, so that ChunkedStream.isEndOfInput() does not
propagate the IOException from PushBackInputStream.

Result:

Fixes #3368

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.

8c135cdd55 Add a new constructor without handler parameter to TrafficCounter
Related: #3476

Motivation:

Some users use TrafficCounter for other uses than we originally
intended, such as implementing their own traffic shaper.  In such a
case, a user does not want to specify an AbstractTrafficShapingHandler.

Modifications:

- Add a new constructor that does not require an
  AbstractTrafficShapingHandler, so that a user can use it without it.
- Simplify TrafficMonitoringTask
- Javadoc cleanup

Result:

We open the possibility of using TrafficCounter for other purposes than
just using it with AbstractTrafficShapingHandler.  Eventually, we could
generalize it a little bit more, so that we can potentially use it for
other uses.

200c6efc75 [#3364] Not use VoidChannelPromise in SslHandler to guard against IllegalStateException
Motivation:

SslHandler adds a pending write with an empty buffer and a VoidChannelPromise when a user flush and not pending writes are currently stored. This may produce an IllegalStateException later if the user try to add a ChannelFutureListener to the promise in the next ChannelOutboundHandler.

Modifications:

Replace ctx.voidPromise() with ctx.newPromise()

Result:

392fb764b6 Fix IndexOutOfBoundsException from SslHandler on JDK 8
Motivation:

When SslHandler.unwrap() copies SSL records into a heap buffer, it does
not update the start offset, causing IndexOutOfBoundsException.

Modifications:

- Copy to a heap buffer before calling unwrap() for simplicity
- Do not copy an empty buffer to a heap buffer.
  - unwrap(... EMPTY_BUFFER ...) never involves copying now.
- Use better parameter names for unwrap()
- Clean-up log messages

Result:

- Bugs fixed
- Cleaner code

1bb818bb59 Reduce memory copies when using OpenSslEngine with SslHandler
Motivation:

When using OpenSslEngine with the SslHandler it is possible to reduce memory copies by unwrap(...) multiple ByteBuffers at the same time. This way we can eliminate a memory copy that is needed otherwise to cumulate partial received data.

Modifications:

- Add OpenSslEngine.unwrap(ByteBuffer[],...) method that can be used to unwrap multiple src ByteBuffer a the same time
- Use a CompositeByteBuffer in SslHandler for inbound data so we not need to memory copy
- Add OpenSslEngine.unwrap(ByteBuffer[],...) in SslHandler if OpenSslEngine is used and the inbound ByteBuf is backed by more then one ByteBuffer
- Reduce object allocation

Result:

SslHandler is faster when using OpenSslEngine and produce less GC

50af9b916c Eliminate memory copy in ByteToMessageDecoder whenever possible
Motivation:

Currently when there are bytes left in the cumulation buffer we do a byte copy to produce the input buffer for the decode method. This can put quite some overhead on the impl.

Modification:

- Use a CompositeByteBuf to eliminate the byte copy.
- Allow to specify if a CompositeBytebug should be used or not as some handlers can only act on one ByteBuffer in an efficient way (like SslHandler :( ).

Result:

Performance improvement as shown in the following benchmark.

ea5f38955a Raise an exception when the specified cipher suite is not available
Motivation:

SSL_set_cipher_list() in OpenSSL does not fail as long as at least one
cipher suite is available.  It is different from the semantics of
SSLEngine.setEnabledCipherSuites(), which raises an exception when the
list contains an unavailable cipher suite.

Modifications:

- Add OpenSsl.isCipherSuiteAvailable(String) which checks the
  availability of a cipher suite
- Raise an IllegalArgumentException when the specified cipher suite is
  not available

Modifications:

- Retrieve the list of the available cipher suites when initializing

- Improve CipherSuiteConverter to understand SRP
- Add more test data to CipherSuiteConverterTest
- Add bulk-conversion method to CipherSuiteConverter

Result:

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

2681112080 Fix big transfer and Write traffic shaping issues
Motivation:

Several issues were shown by various ticket (#2900 #2956).
Also use the improvement on writability user management from #3036.
And finally add a mixte handler, both for Global and Channels, with
the advantages of being uniquely created and using less memory and
less shaping.

Issue #2900

When a huge amount of data are written, the current behavior of the
TrafficShaping handler is to limit the delay to 15s, whatever the delay
the previous write has. This is wrong, and when a huge amount of writes
are done in a short time, the traffic is not correctly shapened.

Moreover, there is a high risk of OOM if one is not using in his/her own
handler for instance ChannelFuture.addListener() to handle the write
bufferisation in the TrafficShapingHandler.

This fix use the "user-defined writability flags" from #3036 to
allow the TrafficShapingHandlers to "user-defined" managed writability
directly, as for reading, thus using the default isWritable() and
channelWritabilityChanged().
This allows for instance HttpChunkedInput to be fully compatible.

The "bandwidth" compute on write is only on "acquired" write orders, not
on "real" write orders, which is wrong from statistic point of view.

Issue #2956

When using GlobalTrafficShaping, every write (and read) are
synchronized, thus leading to a drop of performance.
ChannelTrafficShaping is not touched by this issue since synchronized is
then correct (handler is per channel, so the synchronized).

Modifications:
The current write delay computation takes into account the previous
write delay and time to check is the 15s delay (maxTime) is really
exceeded or not (using last scheduled write time). The algorithm is
simplified and in the same time more accurate.

This proposal uses the #3036 improvement on user-defined writability
flags.

When the real write occurs, the statistics are update accordingly on a
new attribute (getRealWriteThroughput()).

To limit the synchronisations, all synchronized on
GlobalTrafficShapingHandler on submitWrite were removed. They are
replaced with a lock per channel (since synchronization is still needed
to prevent unordered write per channel), as in the sendAllValid method
for the very same reason.
Also all synchronized on TrafficCounter on read/writeTimeToWait() are
removed as they are unnecessary since already locked before by the
caller.
Still the creation and remove operations on lock per channel (PerChannel
object) are synchronized to prevent concurrency issue on this critical
part, but then limited.

Additionnal changes:
1) Use System.nanoTime() instead of System.currentTimeMillis() and
minimize calls
2) Remove / 10 ° 10 since no more sleep usage
3) Use nanoTime instead of currentTime such that time spend is computed,
not real time clock. Therefore the "now" relative time (nanoTime based)
is passed on all sub methods.
4) Take care of removal of the handler to force write all pending writes
and release read too
8) Review Javadoc to explicit:

- recommandations to take into account isWritable

- recommandations to provide reasonable message size according to
traffic shaping limit

- explicit "best effort" traffic shaping behavior when changing
configuration dynamically

Add a MixteGlobalChannelTrafficShapingHandler which allows to use only one
handler for mixing Global and Channel TSH. I enables to save more memory and
tries to optimize the traffic among various channels.

Result:
The traffic shaping is more stable, even with a huge number of writes in
short time by taking into consideration last scheduled write time.

The current implementation of TrafficShapingHandler using user-defined
writability flags and default isWritable() and
fireChannelWritabilityChanged works as expected.

The statistics are more valuable (asked write vs real write).

The Global TrafficShapingHandler should now have less "global"
synchronization, hoping to the minimum, but still per Channel as needed.

The GlobalChannel TrafficShapingHandler allows to have only one handler for all channels while still offering per channel in addition to global traffic shaping.

And finally maintain backward compatibility.

- Add various extra methods to OpenSslSessionContext for extra functionality
- Return OpenSslSessionContext when OpenSslEngine.getSession().getContext() is called.
- Add sessionContext() to SslContext
- Move OpenSsl specific session operations to OpenSslSessionContext and mark the old methods @deprecated

5c57b5de5b Check for errors without object allocation
Motivation:

At the moment we use SSL.getLastError() in unwrap(...) to check for error. This is very inefficient as it creates a new String for each check and we also use a String.startsWith(...) to detect if there was an error we need to handle.

Modifications:

Use SSL.getLastErrorNumber() to detect if we need to handle an error, as this only returns a long and so no String creation happens. Also the detection is much cheaper as we can now only compare longs. Once an error is detected the lately SSL.getErrorString(long) is used to conver the error number to a String and include it in log and exception message.

Result:

Performance improvements in OpenSslEngine.unwrap(...) due less object allocation and also faster comparations.

When using client auth it is sometimes needed to use a custom TrustManagerFactory.

Modifications:

Allow to pass in TrustManagerFactory

Result:

It's now possible to use custom TrustManagerFactories for JdkSslServerContext and OpenSslServerContext

393e3ea383 Use TrustManager for certificate verification
Motivation:

To make OpenSsl*Context a drop in replacement for JdkSsl*Context we need to use TrustManager.

Modifications:

Correctly hook in the TrustManager

Result:

Better compatibility

473c23aec9 Allow to enable client authentication on the OpenSslEngine
Motivation:

At the moment there is no way to enable client authentication when using OpenSslEngine. This limits the uses of OpenSslEngine.

Modifications:

Add support for different authentication modes.

Result:

OpenSslEngine can now also be used when client authenticiation is needed.

87eca066da More complete OpenSslEngine SSLSession implementation
Motivation:

The current SSLSession implementation used by OpenSslEngine does not support various operations and so may not be a good replacement by the SSLEngine provided by the JDK implementation.

Modifications:

- Add SSLSession.getCreationTime()
- Add SSLSession.getLastAccessedTime()
- Add SSLSession.putValue(...), getValue(...), removeValue(...), getValueNames()
- Add correct SSLSession.getProtocol()
- Ensure OpenSSLEngine.getSession() is thread-safe
- Use optimized AtomicIntegerFieldUpdater when possible

Result:

More complete OpenSslEngine SSLSession implementation

682df517c9 Add OpenSslClientContext to allow creating SslEngine for client side
Motivation:

We only support openssl for server side at the moment but it would be also useful for client side.

Modification:

* Upgrade to new netty-tcnative snapshot to support client side openssl support
* Add OpenSslClientContext which can be used to create SslEngine for client side usage
* Factor out common logic between OpenSslClientContext and OpenSslServerContent into new abstract base class called OpenSslContext
* Correctly detect handshake failures as soon as possible
* Guard against segfault caused by multiple calls to destroyPools(). This can happen if OpenSslContext throws an exception in the constructor and the finalize() method is called later during GC

Result:

openssl can be used for client and servers now.
