Add a null check to method TestUtils.compressHeapDumps (#10053)
Motivation:

java.io.File.listFiles() may return null and cause a unexpected NPE.

Modification:

Add a null check for variable files. And if variable files is null, the compressHeapDumps method will just return after logging a error message.

Result:

Fix the potential NPE.

Use @SuppressJava6Requirement for animal sniffer plugin to ensure we always guard correctly (#9655)
Motivation:

We can use the `@SuppressJava6Requirement` annotation to be more precise about when we use Java6+ APIs. This helps us to ensure we always protect these places.

Modifications:

Make use of `@SuppressJava6Requirement` explicit

Result:

Fixes https://github.com/netty/netty/issues/2509.

99a4cecec6 Fix NioEventLoopTest#testChannelsRegistered flakiness (#9650)
Motivation

NioEventLoopTest#testChannelsRegistered() fails intermittently due to
use of SingleThreadEventLoop#channelsRegistered() which is not
threadsafe and unreliable when called from outside the event loop.

Modifications

Add static registeredChannels method to NioEventLoopTest and
AbstractSingleThreadEventLoopTest to call from the tests via event loop
instead of directly.

Result

Hopefully fewer test failures

170e4deee6 Fix event loop shutdown timing fragility (#9616)
Motivation

The current event loop shutdown logic is quite fragile and in the
epoll/NIO cases relies on the default 1 second wait/select timeout that
applies when there are no scheduled tasks. Without this default timeout
the shutdown would hang indefinitely.

The timeout only takes effect in this case because queued scheduled
tasks are first cancelled in
SingleThreadEventExecutor#confirmShutdown(), but I _think_ even this
isn't robust, since the main task queue is subsequently serviced which
could result in some new scheduled task being queued with much later
deadline.

It also means shutdowns are unnecessarily delayed by up to 1 second.

Modifications

- Add/extend unit tests to expose the issue
- Adjust SingleThreadEventExecutor shutdown and confirmShutdown methods
to explicitly add no-op tasks to the taskQueue so that the subsequent
event loop iteration doesn't enter blocking wait (as looks like was
originally intended)

Results

Faster and more robust shutdown of event loops, allows removal of the
default wait timeout

Correctly reset cached local and remote address when disconnect() is called (#9545)
Motivation:

We should correctly reset the cached local and remote address when a Channel.disconnect() is called and the channel has a notion of disconnect vs close (for example DatagramChannel implementations).

Modifications:

- Correctly reset cached kicak abd remote address
- Update testcase to cover it and so ensure all transports work in a consistent way

Result:

Correctly handle disconnect()

21720e4a78 Allow to build on powerpc
Motivation:

At the moment it is not possible to build netty on a power 8 systems.

Modifications:

- Improve detection of the possibility of using Conscrypt
- Skip testsuite-shading when not on x86_64 as this is the only platform for which we build tcnative atm
- Only include classifier if on x86_64 for tcnative as dependency as this is the only platform for which we build tcnative atm
- Better detect if UDT test can be run

Result:

Correctly handle IPV6-mapped-IPV4 addresses in native code when receiving datagrams (#9560)
Motivation:

291f80733a introduced a change to use a byte[] to construct the InetAddress when receiving datagram messages to reduce the overhead. Unfortunally it introduced a regression when handling IPv6-mapped-IPv4 addresses and so produced an IndexOutOfBoundsException when trying to fill the byte[] in native code.

Modifications:

- Correctly use the offset on the pointer of the address.
- Add testcase
- Make tests more robust and include more details when the test fails

Result:

No more IndexOutOfBoundsException

Also support sendmmsg(...) on connected UDP channels when using native epoll transport (#9536)
Motivation:

We should also use sendmmsg on connected channels whenever possible to reduce the overhead of syscalls.

Modifications:

No matter if the channel is connected or not try to use sendmmsg when supported to reduce the overhead of syscalls

Result:

Better performance on connected UDP channels due less syscalls

Correctly handle ipv6 mapped ipv4 addresses when using recvmmsg (#9541)
Motivation:

394a1b3485 introduced the possibility to use recvmmsg(...) but did not correctly handle ipv6 mapped ip4 addresses to make it consistent with other transports.

Modifications:

- Correctly handle ipv6 mapped ipv4 addresses by only copy over the relevant bytes
- Small improvement on how to detect ipv6 mapped ipv4 addresses by using memcmp and not byte by byte compare
- Adjust test to cover this bug

Result:

Correctly handle ipv6 mapped ipv4 addresses

Add support for recvmmsg when using epoll transport (#9509)
Motivation:

When using datagram sockets which need to handle a lot of packets it makes sense to use recvmmsg to be able to read multiple datagram packets with one syscall.

Modifications:

- Add support for recvmmsg on linux
- Add new EpollChannelOption.MAX_DATAGRAM_PACKET_SIZE
- Add tests

Result:

Fixes https://github.com/netty/netty/issues/8446.

Add support for loopbackmode and accessing the configured interface when using epoll native transport with multicast (#9218)
Motivation:

We did not have support for enable / disable loopback mode in our native epoll transport and also missed the implemention to access the configured interface.

Modifications:

Add implementation and adjust test to cover it

Result:

70731bfa7e Added UDP multicast (with caveats: getInterface, getNetworkInterface, block or loopback-mode-disabled operations).
Motivation:

Provide epoll/native multicast to support high load multicast users (we are using it for a high load telecomm app at my day job).

Modification:

Added support for source specific and any source multicast for epoll transport. Some caveats: no support for disabling loop back mode, retrieval of interface and block operation, all of which tend to be less frequently used.

Result:

Provides epoll transport multicast for common use cases.

e348bd9217 KQueueEventLoop | EpollEventLoop may incorrectly update registration when FD is reused.
Motivation:

The current KQueueEventLoop implementation does not process concurrent domain socket channel registration/unregistration in the order they actual
happen since unregistration are delated by an event loop task scheduling. When a domain socket is closed, it's file descriptor might be reused
quickly and therefore trigger a new channel registration using the same descriptor.

Consequently the KQueueEventLoop#add(AbstractKQueueChannel) method will overwrite the current inactive channels having the same descriptor
and the delayed KQueueEventLoop#remove(AbstractKQueueChannel) will remove the active channel that replaced the inactive one.

As active channels are registered, events for this file descriptor won't be processed anymore and the channels will never be closed.

The same problem can also happen in EpollEventLoop. Beside this we also may never remove the AbstractEpollChannel from the internal map
when it is unregistered which will prevent it from be GC'ed

Modifications:

- Change logic of native KQueue and Epoll implementations to ensure we correctly handle the case of FD reuse
- Only try to update kevent / epoll if the Channel is still open (as otherwise it will be handled by kqueue / epoll itself)
- Correctly remove AbstractEpollChannel from internal map in all cases
- Make implementation of closeAll() consistent for Epoll and KQueueEventLoop

Result:

KQueue and Epoll native transports correctly handle FD reuse

Make Multicast tests more robust (#9053)
Motivation:

86dd388637 reverted the usage of IPv6 Multicast test. This commit makes the whole multicast testing a lot more robust by selecting the correct interface in any case and also reverts the `@Ignore`

Modifications:

- More robust multicast testing by selecting the right NetworkInterface
- Remove the `@Ignore` again for the IPv6 test

Result:

Add IPv6 multicast test to testsuite (#9037)
Motivation:

We currently only cover ipv4 multicast in the testsuite but we should also have tests for ipv6.

Modifications:

e7b3195570 Support ALLOW_HALF_CLOSURE channel option on Unix domain socket. (#8932)
Motivation:

Since DomainSocketChannel is a DuplexChannel,  which be able to shutdown input or output individually on demands, but ALLOW_HALF_CLOSURE channel option has not been supported yet.

I thought this could be a missing feature of Unix domain socket, so here the PR for it.

Modifications:

1. Added allHalfClosure property both in  EpollDomainSocketChannelConfig and KQueueDomainSocketChannelConfig,
2. Enabled isAllowHalfClosure method of native channel to support domain channel config,
3. Created EpollDomainSocketShutdownOutputByPeerTest and KQueueDomainSocketShutdownOutputByPeerTest to verify the change.

Result:

ALLOW_HALF_CLOSURE channel option can be set with DomainSocketChannel, and no more warning of Unknown channel option 'ALLOW_HALF_CLOSURE'.

Use maven plugin to prevent API/ABI breakage as part of build process (#8904)
Motivation:

Netty is very widely used which can lead to a lot of pain when we break API / ABI. We should make use japicmp-maven-plugin during the build to verify we do not introduce breakage by mistake.

Modifications:

- Add japicmp-maven-plugin to the build process
- Fix a method signature change in HttpProxyHandler that was flagged as a possible problem.

Result:

Ensure no API/ABI breakage accour between releases.

Adjust tests to be able to build / test when using IBM J9 / OpenJ9 (#8900)
Motivation:

We should run a CI job using J9 to ensure netty also works when using different JVMs.

Modifications:

- Adjust PooledByteBufAllocatorTest to be able to complete faster when using a JVM which takes longer when joining Threads (this seems to be the case with J9).
- Skip UDT tests on J9 as UDT is not supported there.

Result:

Be able to run CI against J9.

DefaultFileRegion.transferTo with invalid count may cause busy-spin (#8885)
Motivation:

`DefaultFileRegion.transferTo` will return 0 all the time when we request more data then the actual file size. This may result in a busy spin while processing the fileregion during writes.

Modifications:

- If we wrote 0 bytes check if the underlying file size is smaller then the requested count and if so throw an IOException
- Add DefaultFileRegionTest
- Add a test to the testsuite

Result:

Support using an Executor to offload blocking / long-running tasks wh… (#8847)
Motivation:

The SSLEngine does provide a way to signal to the caller that it may need to execute a blocking / long-running task which then can be offloaded to an Executor to ensure the I/O thread is not blocked. Currently how we handle this in SslHandler is not really optimal as while we offload to the Executor we still block the I/O Thread.

Modifications:

- Correctly support offloading the task to the Executor while suspending processing of SSL in the I/O Thread
- Add new methods to SslContext to specify the Executor when creating a SslHandler
- Remove @deprecated annotations from SslHandler constructor that takes an Executor
- Adjust tests to also run with the Executor to ensure all works as expected.

Result:

Be able to offload long running tasks to an Executor when using SslHandler. Partly fixes https://github.com/netty/netty/issues/7862 and https://github.com/netty/netty/issues/7020.

Reduce GC produced by native DatagramChannel implementations when in connected mode. (#8806)
Motivation:

In the native code EpollDatagramChannel / KQueueDatagramChannel creates a DatagramSocketAddress object for each received UDP datagram even when in connected mode as it uses the recvfrom(...) / recvmsg(...)  method. Creating these is quite heavy in terms of allocations as internally, char[], String, Inet4Address, InetAddressHolder, InetSocketAddressHolder, InetAddress[], byte[] objects are getting generated when constructing the object. When in connected mode we can just use regular read(...) calls which do not need to allocate all of these.

Modifications:

- When in connected mode use read(...) and NOT recvfrom(..) / readmsg(...) to reduce allocations when possible.
- Adjust tests to ensure read works as expected when in connected mode.

Result:

Less allocations and GC when using native datagram channels in connected mode. Fixes https://github.com/netty/netty/issues/8770.

- Adjust unit tests for semantics provided by TLSv1.3
- Correctly handle custom Provider implementations that not support TLSv1.3

Adjust SSL related tests to be more correct and so pass in the next EA release of java11. (#8162)
Motivation:

In some of our tests we not correctly init the SSLEngine before trying to perform a handshake which can cause an IllegalStateException. While this not happened in previous java releases it does now on Java11 (which is "ok" as its even mentioned in the api docs). Beside this how we selected the ciphersuite to test renegotation was not 100 % safe.

Modifications:

- Correctly init SSLEngine before using it
- Correctly select ciphersuite before testing for renegotation.

Result:

More correct tests and also pass on next java11 EA release.

12f6500a4f Epoll and Kqueue shouldn't read by default (#8024)
Motivation:
Epoll and Kqueue channels have internal state which forces
a single read operation after channel construction. This
violates the Channel#read() interface which indicates that
data shouldn't be delivered until this method is called.
The behavior is also inconsistent with the NIO transport.

Modifications:
- Epoll and Kqueue shouldn't unconditionally read upon
initialization, and instead should rely upon Channel#read()
or auto_read.

Result:
Epoll and Kqueue are more consistent with NIO.

Java11 disallow draining any remaining bytes from the socket if a write causes a connection reset. This should be completely safe to do. At the moment if a write is causing a connection-reset you basically loose all the pending bytes that are sitting on the socket and are waiting to be read.

This happens because SocketOutputStream.write(…) may call AbstractPlainSocketImpl.setConnectionReset(…). Once this method is called any read(…) call will just throw a SocketException without even attempt to read any remaining data.

 - http://mail.openjdk.java.net/pipermail/net-dev/2018-May/011511.html

Modifications:

Tolarate if remaining bytes could not be read when using OIO.

Result:

Be able to build Netty and run testsuite while using Java11

Revert workaround in test for Java 11 as it produces a connection-reset as expected now. (#7951)
Motivation:

We added a workaround for Java 11 as it not produced a connect-reset when SO_LINGER with 0 was set and NIO was used. This was fixed in the latest ea release of Java 11:

 - http://hg.openjdk.java.net/jdk/jdk/rev/ea54197f4fe4
 - https://bugs.openjdk.java.net/browse/JDK-8203059

Modifications:

Revert workaround.

Result:

Test that Java 11 behave the same way as earlier Java versions again.

Ensure Netty can be build with Java 11 (#7926)
Motivation:

Java 11 will be out soon, so we should be able to build (and run tests) netty.

Modifications:

- Add dependency that is needed till Java 11
- Adjust tests so these also pass on Java 11 (SocketChannelImpl.close() behavious a bit differently now).

Result:

Build also works (and tests pass) on Java 11.

Make build pass on Java 10 (#7922)
Motivation:

Java 10 is out so we should be able to build netty with it (and run the tests).

Modifications:

- Update Mockito and JBoss Marshalling to support Java 10
- Fix unit test to not depend on specific cipher which is not present in Java 10 anymore

Result:

Netty builds (and runs all tests) when using Java 10

b818852cdb Update DatagramPacket.recipient() to return the actual destination IP (#7879)
Motivation:

DatagramPacket.recipient() doesn't return the actual destination IP, but the IP the app is bound to.

Modification:

- IP_RECVORIGDSTADDR option is enabled for UDP sockets, which allows retrieval of ancillary information containing the original recipient.
- _recvFrom(...) function from transport-native-unix-common/src/main/c/netty_unix_socket.c is modified such that if IP_RECVORIGDSTADDR is set, recvmsg is used instead of recvfrom; enabling the retrieval of the original recipient.
- DatagramSocketAddress also contains a 'local' address, representing the recipient.
- EpollDatagramChannel is updated to return the retrieved recipient address instead of the address the channel is bound to.

Result:

Fixes #4950.

ed0668384b NIO read spin event loop spin when half closed (#7801)
Motivation:
AbstractNioByteChannel will detect that the remote end of the socket has
been closed and propagate a user event through the pipeline. However if
the user has auto read on, or calls read again, we may propagate the
same user events again. If the underlying transport continuously
notifies us that there is read activity this will happen in a spin loop
which consumes unnecessary CPU.

Modifications:
- AbstractNioByteChannel's unsafe read() should check if the input side
of the socket has been shutdown before processing the event. This is
consistent with EPOLL and KQUEUE transports.
- add unit test with @normanmaurer's help, and make transports consistent with respect to user events

Result:
No more read spin loop in NIO when the channel is half closed.

a53f716ca1 Call correct super methods in test.
Motivation:

We called the wrong super method in the test and also had a few unused imports.

Modifications:

Fix super method call and cleanup.

Result:

More correct test and cleanup.

ce241bd11e Epoll flush/writabilityChange deadlock
Motivation:
b215794de3 recently introduced a change in behavior where writeSpinCount provided a limit for how many write operations were attempted per flush operation. However when the write quantum was meet the selector write flag was not cleared, and the channel unsafe flush0 method has an optimization which prematurely exits if the write flag is set. This may lead to no write progress being made under the following scenario:
- flush is called, but the socket can't accept all data, we set the write flag
- the selector wakes us up because the socket is writable, we write data and use the writeSpinCount quantum
- we then schedule a flush() on the EventLoop to execute later, however it the flush0 optimization prematurely exits because the write flag is still set

In this scenario the socket is still writable so the EventLoop may never notify us that the socket is writable, and therefore we may never attempt to flush data to the OS.

Modifications:
- When the writeSpinCount quantum is exceeded we should clear the selector write flag

Result:
Fixes https://github.com/netty/netty/issues/7729

062d926912 Remove remote initiated renegotiation support
Motivation:
We recently removed support for renegotiation, but there are still some hooks to attempt to allow remote initiated renegotiation to succeed. The remote initated renegotiation can be even more problematic from a security stand point and should also be removed.

Modifications:
- Remove state related to remote iniated renegotiation from OpenSslEngine

Result:
More renegotiation code removed from the OpenSslEngine code path.

IovArray#add return value resulted in more ByteBufs being added during iteration
Motivation:
IovArray implements MessageProcessor, and the processMessage method will continue to be called during iteration until it returns true. A recent commit b215794de3 changed the return value to only return true if any component of a CompositeByteBuf was added as a result of the method call. However this results in the iteration continuing, and potentially subsequent smaller buffers maybe added, which will result in out of order writes and generally corrupts data.

Modifications:
- IovArray#add should return false so that the MessageProcessor#processMessage will stop iterating.

Result:
Native transports which use IovArray will not corrupt data during gathering writes of CompositeByteBuf objects.

b6c42f6547 Use 198.51.100.254 as BAD_HOST for tests.
Motivation:

At the moment we use netty.io as BAD_HOST with an port that we know is timing out. This may change in the future so we should better use 198.51.100.254 which is specified as "for documentation only".

Modifications:

Replace netty.io with 198.51.100.254 in tests that depend on BAD_HOST.

Result:

More future proof code.
