fdc396674e [#3531] Create SslContext.Builder
Motivation:

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

Modifications:

New Builder class. The existing factory methods must be left as-is for
backward compatibility.

Result:

Fixes #3531

3307686bda [#3539] Correctly handle EPOLLRDHUP
Motivation:

As we missed to correctly handle EPOLLRDHUP we produce an IOException which is unnessary. This leads
to have exceptionCaught(...) methods called.

Modifications:

When EPOLLRDHUP was received just close the socket and fail all pending writes.

Result:

Correctly handle of EPOLLRDHUP and so not miss-leading exceptions.

8843d2b1a1 [#2925] Bug fix for NormalMemoryRegionCache overbooked for PoolThreadCache
Motivation:

When create NormalMemoryRegionCache for PoolThreadCache, we overbooked
cache array size. This means unnecessary overhead for thread local cache
as we will create multi cache enties for each element in cache array.

Modifications:

change:
int arraySize = Math.max(1, max / area.pageSize);
to:
int arraySize = Math.max(1, log2(max / area.pageSize) + 1);

Result:

Now arraySize won't introduce unnecessary overhead.

ddd19f4f21 Dereference when calling PooledByteBuf.deallocate()
Motivation:

We missed to dereference the chunk and tmpNioBuf when calling deallocate(). This means the GC can not collect these as we still hold a reference while have the PooledByteBuf in the recycler stack.

Modifications:

Dereference chunk and tmpNioBuf.

Result:

GC can collect things.

bfee39b318 [#3592] Flush when writing HttpChunkedInput
Motivation:

We missed to flush the channel when using HttpChunkedInput (this is done when using SSL). This will result in a stale.

Modifications:

Replace ctx.write(...) with ctx.writeAndFlush(...)

Result:

Correctly working example.

30f60ac68a Change PoolThreadCache to use LIFO for better cache performance
Motiviation:

At the moment we use FIFO for the PoolThreadCache which is sub-optimal as this may reduce the changes to have the cached memory actual still in the cpu-cache.

Modification:

- Change to use LIFO as this increase the chance to be able to serve buffers from the cpu-cache

Results:

Faster allocation out of the ThreadLocal cache.

97a3308c7e 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.

ecf1b558d9 Motivation: If there are no readable bytes, it's unnecessary to go through javaChannel().write().
Modification:
If the readableBytes() is zero, then just return.

Result:
The logic can be easy to understand and a little faster than before.

2ab2e2d6b7 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.

4d8f824358 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

28caa873b3 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

0c6ba4aab6 Add supported for X509ExtendedTrustManager when using OpenSslEngine
Motivation:

For some use cases X509ExtendedTrustManager is needed as it allows to also access the SslEngine during validation.

Modifications:

Add support for X509ExtendedTrustManager on java >= 7

Result:

It's now possible to use X509ExtendedTrustManager with OpenSslEngine

0222f41233 Enforce a release is made with JDK 1.7 (and not w/ 1.8+)
Motivations:

JDK 1.8 adds default methods to collections classes that reference
classes that don't exist in JDK 7. That's binary compatible,
but not source compatible.

Modifications:

Enforce JDK version to be 1.7.* when releasing

Result:

Fixes #3548

c1ac64fb82 Safely encode Strings to ASCII
(Ported @luciferous's changes against 3.10)

Motivation:

The current implementation of the encoder writes each character of the
String as a single byte to the buffer, however not all characters are
mappable to a single byte.

Modifications:

If a character is outside the ASCII range, it's converted to '?'.

Result:

A safer encoder for String to ASCII, which substitutes unmappable

9091e66e15 Hide password in exception messages of SocksAuthRequest
Related: #3504

Motivation:

There are two places in the SocksAuthRequest constructor where an
IllegalArgumentException is thrown with a password as part of the
exception message.

This constitutes mishandling of confidential information, which can
compromise user privacy and is flagged as critical by security scanners.

Modifications:

Mask the password in the exception messages

Result:

No unexpected password leak

034e0bd8d2 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.

01c3fd3ace Add support for byte order to LengthFieldPrepender
Motivation:

While the LengthFieldBasedFrameDecoder supports a byte order the LengthFieldPrepender does not.
That means that I can simply add a LengthFieldBasedFrameDecoder with ByteOrder.LITTLE_ENDIAN to my pipeline
but have to write my own Encoder to write length fields in little endian byte order.

Modifications:

Added a constructor that takes a byte order and all other parameters.
All other constructors delegate to this one with ByteOrder.BIG_ENDIAN.
LengthFieldPrepender.encode() uses this byte order to write the length field.

Result:

LengthFieldPrepender will write the length field in the defined byte order.

fadbf7df52 Respect -Djava.net.preferIPv4Stack when using epoll transport
Motivation:

On a system where ipv4 and ipv6 are supported a user may want to use -Djava.net.preferIPv4Stack=true to restrict it to use ipv4 only.
This is currently ignored with the epoll transport.

Modifications:

Respect java.net.preferIPv4Stack system property.

Result:

-Djava.net.preferIPv4Stack=true will have the effect the user is looking for.

54293003ef 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.

2c14406b55 Fix header and initial line length counting
Related: #3445

Motivation:

HttpObjectDecoder.HeaderParser does not reset its counter (the size
field) when it failed to find the end of line.  If a header is split
into multiple fragments, the counter is increased as many times as the
number of fragments, resulting an unexpected TooLongFrameException.

Modifications:

- Add test cases that reproduces the problem
- Reset the HeaderParser.size field when no EOL is found.

Result:

which are actually provided by `ByteBufUtil`.

Modifications:

 Sentence moved to `ByteBufUtil` javadoc.
