3344cd21ac Wrap operations requiring SocketPermission with doPrivileged blocks
Motivation:

Currently Netty does not wrap socket connect, bind, or accept
operations in doPrivileged blocks. Nor does it wrap cases where a dns
lookup might happen.

This prevents an application utilizing the SecurityManager from
isolating SocketPermissions to Netty.

Modifications:

I have introduced a class (SocketUtils) that wraps operations
requiring SocketPermissions in doPrivileged blocks.

Result:

A user of Netty can grant SocketPermissions explicitly to the Netty
jar, without granting it to the rest of their application.

0bc30a123e Eliminate usage of releaseLater(...) to reduce memory usage during tests
Motiviation:

We used ReferenceCountUtil.releaseLater(...) in our tests which simplifies a bit the releasing of ReferenceCounted objects. The problem with this is that while it simplifies stuff it increase memory usage a lot as memory may not be freed up in a timely manner.

Modifications:

- Deprecate releaseLater(...)
- Remove usage of releaseLater(...) in tests.

Result:

Less memory needed to build netty while running the tests.

7e62f9fcdb SocketSslEchoTest failure
Motivation:
8ba5b5f740 removed some ciphers from the default list, and SocketSslEchoTest had one of these ciphers hard coded in the test. The test will fail if the cihper is not supported by default.

Modifications:
SocketSslEchoTest should ensure a cipher is used which will be supported by the peer

Result:
Test result no longer depends upon default cipher list.

2c4a7a2539 [#5800] Support any FileRegion implementation when using epoll transport
Motivation:

At the moment only DefaultFileRegion is supported when using the native epoll transport.

Modification:

- Add support for any FileRegion implementation
- Add test case

Result:

Also custom FileRegion implementation are supported when using the epoll transport.

eb450d8b2f Correct throw ClosedChannelException when attempt to call shutdown*(...) on closed EpollSocketChannel.
Motivition:

NIO throws ClosedChannelException when a user tries to call shutdown*() on a closed Channel. We should do the same for the EPOLL transport

Modification:

Throw ClosedChannelException when a user tries to call shutdown*() on a closed channel.

Result:

Consistent behavior.

d3cb95ef00 Make NIO and EPOLL transport connect errors more consistent with the JDK
Motivation:

The NIO transport used an IllegalStateException if a user tried to issue another connect(...) while the connect was still in process. For this case the JDK specified a ConnectPendingException which we should use. The same issues exists in the EPOLL transport. Beside this the EPOLL transport also does not throw the right exceptions for ENETUNREACH and EISCONN errno codes.

Modifications:

- Replace IllegalStateException with ConnectPendingException in NIO and EPOLL transport
- throw correct exceptions for ENETUNREACH and EISCONN in EPOLL transport
- Add test case

Result:

More correct error handling for connect attempts when using NIO and EPOLL transport

5e148d5670 [#5639] Ensure fireChannelActive() is also called if Channel is closed in connect promise.
Motivation:

We need to ensure we also call fireChannelActive() if the Channel is directly closed in a ChannelFutureListener that is belongs to the promise for the connect. Otherwise we will see missing active events.

Modifications:

Ensure we always call fireChannelActive() if the Channel was active.

Result:

No missing events.

2c1f17faa2 Throw correct NotYetConnectedException when ENOTCONN errno is set
Motivation:

We should throw a NotYetConnectedException when ENOTCONN errno is set. This is also consistent with NIO.

Modification:

Throw correct exception and add test case

Result:

More correct and consistent behavior.

e200e4811b SocketRstTest fails due to exception message check
Motivation:
For lack of a better way the SocketRstTest inspects the content of the exception message to check if a RST occurred. However on windows the exception message is different than on other Unix based platforms and the assertion statement fails.

Modifications:
- Hack another string check in the unit test

Result:
SocketRstTest passes on windows

7b25402e80 Add CompositeByteBuf.addComponent(boolean ...) method to simplify usage
Motivation:

At the moment the user is responsible to increase the writer index of the composite buffer when a new component is added. We should add some methods that handle this for the user as this is the most popular usage of the composite buffer.

Modifications:

Add new methods that autoamtically increase the writerIndex when buffers are added.

Result:

Easier usage of CompositeByteBuf.

3a9f472161 Make retained derived buffers recyclable
Related: #4333 #4421 #5128

Motivation:

slice(), duplicate() and readSlice() currently create a non-recyclable
derived buffer instance. Under heavy load, an application that creates a
lot of derived buffers can put the garbage collector under pressure.

Modifications:

- Add the following methods which creates a non-recyclable derived buffer
  - retainedSlice()
  - retainedDuplicate()
  - readRetainedSlice()
- Add the new recyclable derived buffer implementations, which has its
  own reference count value
- Add ByteBufHolder.retainedDuplicate()
- Add ByteBufHolder.replace(ByteBuf) so that..
  - a user can replace the content of the holder in a consistent way
  - copy/duplicate/retainedDuplicate() can delegate the holder
    construction to replace(ByteBuf)
- Use retainedDuplicate() and retainedSlice() wherever possible
- Miscellaneous:
  - Rename DuplicateByteBufTest to DuplicatedByteBufTest (missing 'D')
  - Make ReplayingDecoderByteBuf.reject() return an exception instead of
    throwing it so that its callers don't need to add dummy return
    statement

Result:

Derived buffers are now recycled when created via retainedSlice() and
retainedDuplicate() and derived from a pooled buffer

eb14e5b2f5 Ensure EpollSocketChannel.localAddress() returns correct address after connect(...) call.
Motivation:

We missed to correctly retrieve the localAddress() after we called Socket.connect(..) and so the user would always see an incorrect address when calling EpollSocketChannel.localAddress().

Modifications:

- Ensure we always retrieve the localAddress() after we called Socket.connect(...) as only after this we will be able to receive the correct address.
- Add unit test

Result:

Correct and consistent behaviour across different transports (NIO/OIO/EPOLL).

5b48fc284e Make OIO/NIO/EPOLL autoReadClear consistent
Motivation:
OIO/NIO use a volatile variable to track if a read is pending. EPOLL does not use a volatile an executes a Runnable on the event loop thread to set readPending to false. These mechansims should be consistent, and not using a volatile variable is preferable because the variable is written to frequently in the event loop thread.
OIO also does not set readPending to false before each fireChannelRead operation and may result in reading more data than the user desires.

Modifications:
- OIO/NIO should not use a volatile variable for readPending
- OIO should set readPending to false before each fireChannelRead

Result:
OIO/NIO/EPOLL are more consistent w.r.t. readPending and volatile variable operations are reduced

8dbf5d02e5 EPOLL SO_LINGER=0 sends FIN+RST
Motivation:
If SO_LINGER is set to 0 the EPOLL transport will send a FIN followed by a RST. This is not consistent with the behavior of the NIO transport. This variation in behavior can cause protocol violations in streaming protocols (e.g. HTTP) where a FIN may be interpreted as a valid end to a data stream, but RST may be treated as the data is corrupted and should be discarded.

https://github.com/netty/netty/issues/4170 Claims the behavior of NIO always issues a shutdown when close occurs. I could not find any evidence of this in Netty's NIO transport nor in the JDK's SocketChannel.close() implementation.

Modifications:
- AbstractEpollChannel should be consistent with the NIO transport and not force a shutdown on every close
- FileDescriptor to keep state in a consistent manner with the JDK and not allow a shutdown after a close
- Unit tests for NIO and EPOLL to ensure consistent behavior

Result:
EPOLL is capable of sending just a RST to terminate a connection.

94f2748f1b Upgrade to netty-tcnative-1.1.33.Fork13
Motivation:

netty-tcnative-1.1.33.Fork was released, we should upgrade. Also we should skip renegotiate tests if boringssl is used because boringssl does not support renegotiation.

Modifications:

- Upgrade to netty-tcnative-1.1.33.Fork13
- Skip renegotiate tests if boringssl is used.

Result:

Use newest version of netty-tcnative and be able to build if boringssl is used.

210ebe1354 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.
