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.

661bd86829 Fix flacky test introduced by af2f343648
Motivation:

af2f343648 introduced a test-case which was flacky due of multiple problems:

- we called writeAndFlush(...) in channelRead(...) and assumed it will only be called once. This is true most of the times but it may be called multile times if the data is fragemented.
- we didnt guard against the possibility that channelRead(...) is called with an empty buffer

Modifications:

- Call writeAndFlush(...) in channelActive(...) so we are sure its only called once and close the channel once we wrote the data
- only compare the data after we received a close so we are sure there isnt anything extra received
- check for exception and if we catched one fail the test.

Result:

No flacky test anymore and easier to debug issues that accour because of a catched exception.

FileDescriptor writev core dump
Motivation:
FileDescriptor#writev calls JNI code, and that JNI code dereferences a NULL pointer which crashes the application. This occurs when writing a single CompositeByteBuf object with more than one component.

Modifications:
- Initialize the iovec iterator properly to avoid the core dump
- Fix the array length calculation if we aren't able to fit all the ByteBuffer objects in the iovec array

Result:
No more core dump.

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].

Modifications:

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

Result:

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.

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

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:

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.

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:

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.

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:

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.

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.

58dc7f7902 Do not bother closing SSL enging inbound if the outbound has already been closed.
Motivation:

Invoking the javax.net.ssl.SSLEngine.closeInbound() method will send a
fatal alert and invalidate the SSL session if a close_notify alert has
not been received.
From the javadoc:
If the application initiated the closing process by calling
closeOutbound(), under some circumstances it is not required that the
initiator wait for the peer's corresponding close message. (See section
7.2.1 of the TLS specification (RFC 2246) for more information on
waiting for closure alerts.) In such cases, this method need not be
called.
Always invoking the closeInbound() method without regard to whether or
not the closeOutbound() method has been invoked could lead to
invalidating perfectly valid SSL sessions.

Modifications:

Added an instance variable to track whether the
SSLEngine.closeOutbound() method has been invoked. When the instance
variable is true, the SSLEngine.closeInbound() method doesn't need to be
invoked.

Result:

SSL sessions will not be invalidated if the outbound side has been
closed but a close_notify alert hasn't been received.

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.

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.

563bf24424 Do not use SLF4J/Logback API directly
Motivation:

TrafficShapingHandlerTest uses Logback API directly, which is
discouraged.  Also, it overrides the global default log level, which
silences the DEBUG messages from other tests.

Modifications:

Remove the direct use of Logback API

Result:

The tests executed after TrafficShapingHandlerTest logs their DEBUG
messages correctly.

98a2bb62f5 Log detailed information about renegotiation and traffic
Motivation:

We need more information to understand why SocketSslEchoTest fails
sporadically in the CI machine.

Modifications:

- Refactor SocketSslEchoTest so that it is easier to retrieve the
  information about renegotiation and the current progress

Result:

We will get more information when the test fails.

c7b407e288 Compress the heap dump after tests are finished
Motivation:

Tests sometimes time out because it took too long to compress the
generated heap dump.

Modifications:

- Move the compression logic to a new method 'compressHeapDumps()'
- Call TestUtils.compressHeapDumps() at the end of the tests, so that
  the tests do not fail because of timeout

Result:

JUnit reports the real cause of the test failure instead of timeout
exception.

8d4a97e05b Generate non-test JAR for netty-testsuite
Motivation:

So far, we generated and deployed test JARs to Maven repositories. The
deployed JAR had the classifier 'test-jar'.  The test JAR is consumed by
transport-native-epoll as a test dependency.

The problem is, when netty-transport-native-epoll pulls the test JAR as
a dependency, that Maven resolves its transitive dependencies at
'compile' and 'runtime' scope only, which is incorrect.

I was bitten by this problem recently while trying to add a new
dependency to netty-testsuite.  Because I added a new dependency at the
'test' scope, the new dependency was not pulled transitively by
transport-native-epoll and caused an unexpected build failure.

- d6160208c3
- bf77bb4c3a

Modifications:

- Move all classes in netty-testsuite from src/test to src/main
- Update the 'compile' scope dependencies of netty-testsuite
- Override the test directory configuration properties of the surefire
  plugin
- Do not generate the test JAR anymore
- Update the dependency of netty-transport-native-epoll

Result:

It is less error-prone to add a new dependency to netty-testsuite.

cbbf5eb96b Compress the heap dump generated by TestUtils.dump()
Motivation:

It takes too long to download the heap dump from the CI server.

Modifications:

Compress the heap dump as much as possible.

Result:

When heap dump is generated by certain test failure, the generated heap
dump file is about 3 times smaller than before, although the compression
time will increase the build time when the test fails.

e7cf1dcb98 Test TLS renegotiation with explicit cipher suite change
Motivation:

So far, our TLS renegotiation test did not test changing cipher suite
during renegotiation explicitly.

Modifications:

- Switch the cipher suite during renegotiation

Result:

We are now sure the cipher suite change works.
