aa8bdb5d6b Fix assertion error when closing / shutdown native channel and SO_LINGER is set.
Motivation:

When SO_LINGER is used we run doClose() on the GlobalEventExecutor by default so we need to ensure we schedule all code that needs to be run on the EventLoop on the EventLoop in doClose. Beside this there are also threading issues when calling shutdownOutput(...)

Modifications:

- Schedule removal from EventLoop to the EventLoop
- Correctly handle shutdownOutput and shutdown in respect with threading-model
- Add unit tests

Result:

Fixes [#7159].

c0396818ca Print out the actual cause when an assertion failure happens during DatagramUnicastTest.testSimpleSendWithConnect
Motivation:

We recently saw an assertion failure when running DatagramUnicastTest.testSimpleSendWithConnect.

Modifications:

- Adding more debug infos
- Ensure we always correctly release the buffers.

Result:

More informations when tests fail.

89ecb4b4a4 AutoClose behavior may infinite loop
Motivation:
If AutoClose is false and there is a IoException then AbstractChannel will not close the channel but instead just fail flushed element in the ChannelOutboundBuffer. AbstractChannel also notifies of writability changes, which may lead to an infinite loop if the peer has closed its read side of the socket because we will keep accepting more data but continuously fail because the peer isn't accepting writes.

Modifications:
- If the transport throws on a write we should acknowledge that the output side of the channel has been shutdown and cleanup. If the channel can't accept more data because it is full, and still healthy it is not expected to throw. However if the channel is not healthy it will throw and is not expected to accept any more writes. In this case we should shutdown the output for Channels that support this feature and otherwise just close.
- Connection-less protocols like UDP can remain the same because the channel may disconnected temporarily.
- Make sure AbstractUnsafe#shutdownOutput is called because the shutdown on the socket may throw an exception.

Result:
More correct handling of write failure when AutoClose is false.

505993a2fb Increase test timeout for SocketStringEchoTest
Motivation:
SocketStringEchoTest has been observed to fail on CI servers, but the stack traces still indicate work was being done.

Modifications:
- Increase the test timeout

Result:
Tests have more time to complete, and hopefully less false positive test failures.

8cb5d0fa8c SocketGatheringWriteTest increase timeouts
Motivation:
EpollDomainSocketGatheringWriteTest. testGatheringWriteBig takes on average about 20-25 seconds on the CI servers, but there is a 30 second timeout being applied which leads to what maybe false positive test failures.

Modifications:
- Increase the test timeout to 120 seconds globally and 60 seconds to wait for all writes per test

Result:
Higher timeout for potentially less false positive test failures.

0bf614d9e9 SocketGatheringWriteTest improvements
Motivation:
SocketGatherWriteTest has been observed to fail and it has numerous issues which when resolved may help reduce the test failures.

Modifications:
- A volatile counter and a spin/sleep loop is used to trigger test termination. Incrementing a volatile is generally bad practice and can be avoided in this situation. This mechanism can be replaced by a promise. This mechanism should also trigger upon exception or channel inactive.
- The TestHandler maintains an internal buffer, but it is not released. We now only create a buffer on the server side and release it after comparing the expected results.
- The composite buffer creation logic can be simplified, also the existing composite buffer doesn't take into account the buffer's reader index when building buf2.

Result:
Cleaner test.

- A volatile counter and a spin/sleep loop is used to trigger test termination. Incrementing a volatile is generally bad practice and can be avoided in this situation. This mechanism can be replaced by a promise. This mechanism should also trigger upon exception or channel inactive.
- Asserts are done in the Netty threads. Although these should result in a exceptionCaught the test may not observe these failures because it is spinning waiting for the count to reach the desired value.

f8b495b2f2 Correctly support SO_TIMEOUT for OioDatagramChannel
Motivation:

We need to support SO_TIMEOUT for the OioDatagramChannel but we miss this atm as we not have special handling for it in the DatagramChannelConfig impl that we use. Because of this the following log lines showed up when running the testsuite:

20:31:26.299 [main] WARN  io.netty.bootstrap.Bootstrap - Unknown channel option 'SO_TIMEOUT' for channel '[id: 0x7cb9183c]'

Modifications:

- Add OioDatagramChannelConfig and impl
- Correctly set SO_TIMEOUT in testsuite

Result:

Support SO_TIMEOUT for OioDatagramChannel and so faster execution of datagram related tests in the testsuite

237a4da1b7 Shutting down the outbound side of the channel should not accept future writes
Motivation:
Implementations of DuplexChannel delegate the shutdownOutput to the underlying transport, but do not take any action on the ChannelOutboundBuffer. In the event of a write failure due to the underlying transport failing and application may attempt to shutdown the output and allow the read side the transport to finish and detect the close. However this may result in an issue where writes are failed, this generates a writability change, we continue to write more data, and this may lead to another writability change, and this loop may continue. Shutting down the output should fail all pending writes and not allow any future writes to avoid this scenario.

Modifications:
- Implementations of DuplexChannel should null out the ChannelOutboundBuffer and fail all pending writes

Result:
More controlled sequencing for shutting down the output side of a channel.

4bb89dcc54 Correctly handle connect/disconnect in EpollDatagramChannel / KQueueDatagramChannel
Motivation:

We did not correctly handle connect() and disconnect() in EpollDatagramChannel / KQueueDatagramChannel and so the behavior was different compared to NioDatagramChannel.

Modifications:

- Correct implement connect and disconnect methods
- Share connect and related code
- Add tests

Result:

EpollDatagramChannel / KQueueDatagramChannel also supports correctly connect() and disconnect() methods.

3cdff36821 Update tests to not use TestUtils.getFreePort() and so ensure we not try to use a port that is used by the system in the meantime.
Motivation:

We should not try to detect a free port in tests put just use 0 when bind so there is no race in which the system my bind something to the port we choosen before.

Modifications:

- Remove the usage of TestUtils.getFreePort() in the testsuite
- Remove hack to workaround bind errors which will not happen anymore now

Result:

Less flacky tests.

e6a399a778 Explicit specify hostaddress during tests to ensure testsuite pass on docker (mac)
Motivation:

When run the current testsuite on docker (mac) it will fail a few tests with:

io.netty.channel.AbstractChannel$AnnotatedConnectException: connect(..) failed: Cannot assign requested address: /0:0:0:0:0:0:0:0%0:46607
Caused by: java.net.ConnectException: connect(..) failed: Cannot assign requested address

Modifications:

Specify host explicit as done in other tests to only use ipv6 when really supported.

Result:

Build pass on docker as well

047da11086 Correctly handle ByteBuf implementations which have no memoryAddress when writing to native transport
Motivation:

Commit 3c4dfed08a introduced a regression in handling buffers that have no memoryAddress.

Modifications:

Fix regression and also add unit tests.

Result:

It's possible again to write buffers without memory address.

3c4dfed08a Fix handle of ByteBuf with multi nioBuffer in EpollDatagramChannel and KQueueDatagramChannel
Motivation:
1. special handling of ByteBuf with multi nioBuffer rather than type of CompositeByteBuf (eg. DuplicatedByteBuf with CompositeByteBuf)
2. EpollDatagramUnicastTest and KQueueDatagramUnicastTest passed because CompositeByteBuf is converted to DuplicatedByteBuf before write to channel
3. uninitalized struct msghdr will raise error

Modifications:
1. isBufferCopyNeededForWrite(like isSingleDirectBuffer in NioDatgramChannel) checks wether a new direct buffer is needed
2. special handling of ByteBuf with multi nioBuffer in EpollDatagramChannel, AbstractEpollStreamChannel, KQueueDatagramChannel, AbstractKQueueStreamChannel and IovArray
3. initalize struct msghdr

Result:
handle of ByteBuf with multi nioBuffer in EpollDatagramChannel and KQueueDatagramChannel are ok

2f8fe2af01 Only try to deregister from EventLoop when the native Channel was registered before.
Motivation:

We only can call eventLoop() if we are registered on an EventLoop yet. As we just did this without checking we spammed the log with an error that was harmless.

Modifications:

Check if registered on eventLoop before try to deregister on close.

Result:

Fixes [#6770]

3cc4052963 New native transport for kqueue
Motivation:
We currently don't have a native transport which supports kqueue https://www.freebsd.org/cgi/man.cgi?query=kqueue&sektion=2. This can be useful for BSD systems such as MacOS to take advantage of native features, and provide feature parity with the Linux native transport.

Modifications:
- Make a new transport-native-unix-common module with all the java classes and JNI code for generic unix items. This module will build a static library for each unix platform, and included in the dynamic libraries used for JNI (e.g. transport-native-epoll, and eventually kqueue).
- Make a new transport-native-unix-common-tests module where the tests for the transport-native-unix-common module will live. This is so each unix platform can inherit from these test and ensure they pass.
- Add a new transport-native-kqueue module which uses JNI to directly interact with kqueue

Result:
JNI support for kqueue.

- skip the autobahntestsuite as jython not works with java9
- skip the osgi testsuite as the maven plugin not works with java9

Result:

Build finally passed on java9

f3dd410142 EPOLLRDHUP prematurely marking input as shutdown
Motivation:
When the EPOLLRDHUP event is received we assume that the read side of the FD is no longer functional and force the input state to be shutdown. However if the channel is still active we should rely upon EPOLLIN and read to indicate there is no more data before we update the shutdown state. If we do not do this we may not read all pending data in the FD if the RecvByteBufAllocator doesn't want to consume it all in a single read operation.

Modifications:
- AbstractEpollChannel#epollRdHupReady() shouldn't force shutdown the input if the channel is active

Result:
All data can be read even if the RecvByteBufAllocator doesn't read it all in the current read loop.

a1b5b5dcca EpollRecvByteAllocatorHandle doesn't inform delegate of more data
Motivation:
EpollRecvByteAllocatorHandle intends to override the meaning of "maybe more data to read" which is a concept also used in all existing implementations of RecvByteBufAllocator$Handle but the interface doesn't support overriding. Because the interfaces lack the ability to propagate this computation EpollRecvByteAllocatorHandle attempts to implement a heuristic on top of the delegate which may lead to reading when we shouldn't or not reading data.

Modifications:
- Create a new interface ExtendedRecvByteBufAllocator and ExtendedHandle which allows the "maybe more data to read" between interfaces
- Deprecate RecvByteBufAllocator and change all existing implementations to extend ExtendedRecvByteBufAllocator
- transport-native-epoll should require ExtendedRecvByteBufAllocator so the "maybe more data to read" can be propagated to the ExtendedHandle

Result:
Fixes https://github.com/netty/netty/issues/6303.

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.
