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.

Only use jboss-marshalling when using Java 10 (#7929)
Motivation:

cff87de44c updated jboss-marshalling to 2.0.5.Final but this broke the ability to run tests with Java 7.

Modifications:

Only use 2.0.5.Final if compiled against Java 10 (as before 1.4.x works fine).

Result:

Be able to run tests with Java 7 on the CI.

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

5256d17363 Make osgi testing work with java>=9 by updating to felix framework 5.6.10 (#7923)
Motivation:

Currently, the testing-osgi is set to skip if run with java>=9. That is not necessary when using a newer version of Felix.

Modification:

Update to Felix framework 5.6.10 (which has better jpms support), add some more --add-opens to not have WARN messages, and remove the skipOsgiTestsuite setting from the parent pom.

Result:

OSGi tests run and pass on java>=9.

Always follow cnames even if a matching A or AAAA record was found. (#7919)
Motivation:

At the moment if you do a resolveAll and at least one A / AAAA record is present we will not follow any CNAMEs that are also present. This is different to how the JDK behaves.

Modifications:

- Allows follow CNAMEs.
- Add unit test.

Result:

Fixes https://github.com/netty/netty/issues/7915.

a0ed6ec06c Fix the error message in ReferenceCounted.release (#7921)
Motivation:

When a buffer is over-released, the current error message of `IllegalReferenceCountException` is `refCnt: XXX, increment: XXX`, which is confusing. The correct message should be `refCnt: XXX, decrement: XXX`.

Modifications:

Pass `-decrement` to create `IllegalReferenceCountException`.

Result:

The error message will be `refCnt: XXX, decrement: XXX` when a buffer is over-released.

437849bd93 Fix tiny typo in FixedChannelPool error message (#7918)
Motivation:

Closed `FixedChannelPool` fails acquire and release operations with
`IllegalStateException`s. These exceptions had message
"FixedChannelPooled was closed". Here "FixedChannelPooled" looks like
a typo and should probably be "FixedChannelPool".

Modifications:

Changed exception message to "FixedChannelPool was closed".

Result:

A tiny bit cleaner exception message.

Allow to disable native transport and native ssl support via system property. (#7903)
Motivation:

Sometimes it's useful to disable native transports / native ssl to debug a problem. We should allow to do so with a system property so people not need to adjust code for this.

Modifications:

Add system properties which allow to disable native transport and native ssl.

Result:

Easier to disable native code usage without code changes.

DefaultDnsCache should store more then one Entry per hostname. (#7906)
Motivation:

Due a bug we did never store more then one address per hostname in DefaultDnsCache.

Modifications:

- Correctly store multiple entries per hostname
- Add tests

Result:

DefaultDnsCache correctly stores more then one entry. Also fixes https://github.com/netty/netty/issues/7882 .

Enforce sane upper limit for TTL in DefaultDnsCache. (#7907)
Motivation:

In b47fb81799 we limited the max supported delay to match what our internal implementat can support. Because of this it was possible that DefaultDnsCache produced an IllegalArgumentException when it tried to schedule a expiration > 3 years.

Modifications:

Limit the max supported TTL to 2 years which is safe for all our EventLoop implementations.

Result:

No more exceptions when adding records to the cache with a huge TTL.

Fix race in ChannelReadHandler used during LocalChannel testing. (#7904)
Motivation:

ChannelReadHandler is used in tests added via f4d7e8de14. In the handler we verify the number of messages we receive per read() call but missed to sometimes reset the counter which resulted in exceptions.

Modifications:

Correctly reset read counter in all cases.

Result:

No more unexpected exceptions when running LocalChannel tests.

Correctly handle responses with status 205 and payload. (#7891)
Motivation:

HTTP responses with status of 205 should not contain a payload. We should enforce this.

Modifications:

Correctly handle responses with status 205 and payload by set Content-Length: 0 header and stripping out the content.

Result:

Allow to call AbstractDiskHttpData.setContent(Unpooled.EMPTY_BUFFER) multiple times. (#7890)
Motivation:

It should be possible to call setContent(Unpooled.EMPTY_BUFFER) multiple times just like its possible to do the same with a non empty buffer.

Modifications:

- Correctly reset underlying storage if called multiple times.
- Add tests

Add #ifdef statements so the compilation of the native code not fails on MacOS (#7895)
Motivation:

b818852cdb added support for IP_RECVORIGDSTADDR but did not include any #ifdef statements to ensure its usable at all (which is not the case on MacOS).

Modifications:

Add #ifdef statements to check for IP_RECVORIGDSTADDR.

Result:

Compilation works again on MacOS.

Fix IllegalReferenceCountException when using Http2MultiplexCodec and a DefaultHttp2GoAwayFrame with a non empty ByteBuffer is received. (#7894)
Motivation:

We incorrectly called frame.release() in onHttp2GoAwayFrame which could lead to IllegalReferenceCountExceptions.  The call of release() is inappropriate because the fireChannelRead() in onHttp2Frame() will handle it.

Modifications:

- Not call frame.release()
- Add a unit test

Result:

Fxies https://github.com/netty/netty/issues/7892.

c0ae5e697c DnsAddressResolverGroup to use pluggable DnsNameResolverBuilder (#7793)
Motivation:

Right now to customize DNS name resolver when using DnsAddressResolverGroup
one should subclass implementation and override newNameResolver method when
in fact it's possible to collect all settings in a DnsNameResolverBuilder
instance. Described in #7749.

Modifications:

- Added new constructor for DnsNameResolverBuilder in order to delay
  EventLoop specification

- Added copy() method to DnsNameResolverBuilder to provide an immutable
  copy of the builder

- Added new single-argument constructor for DnsAddressResolverGroup and
  RoundRobinDnsAddressResolverGroup accepting DnsNameResolverBuilder
  instance

- DnsAddressResolverGroup to build a new resolver using DnsNameResolverBuilder
  given instead of creating a new one

- Test cases to check that changing channelFactory after the builder was passed
  to create a DnsNameResolverGroup would not propagate to the name resolver

Result:

Much easier to customize DNS settings w/o subclassing DnsAddressResolverGroup

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.

Don't use VM.maxDirectMemory() on z/OS to retrieve direct memory limit. (#7886)
Motivation:

On z/OS netty initializes this value with 64M, even the direct accessible memory is actually unbounded.

Modifications:

Skip usage of VM.maxDirectMemory() on z/OS.

Result:

More correct direct memory limit detection. Fixes https://github.com/netty/netty/issues/7654.

EventLoop.schedule with big delay fails (#7402)
Motivation:

Using a very huge delay when calling schedule(...) may cause an Selector error when calling select(...) later on. We should gaurd against such a big value.

Modifications:

- Add guard against a very huge value.
- Added tests.

Result:

010dbe3c73 Optimize space usage of FastThreadLocal (#7861)
Motivation:
A FastThreadLocal instance currently occupies 2 slots of InternalThreadLocalMap of every thread. Actually for a FastThreadLocalThread, it does not need to store cleaner flags of FastThreadLocal instances. Besides, using BitSet to store cleaner flags is also better for space usage.

Modification:
Use BitSet to optimize space usage of FastThreadLocal.

Result:
Avoid unnecessary slot occupancy. Cleaner flags are now stored into a BitSet.

1b1f7677ac Implement isWritable and ensureWritable on ReadOnlyByteBufferBuf (#7883)
Motivation:

It should be possible to write a ReadOnlyByteBufferBuf to a channel without errors. However, ReadOnlyByteBufferBuf does not override isWritable and ensureWritable, which can cause some handlers to mistakenly assume they can write to the ReadOnlyByteBufferBuf, resulting in ReadOnlyBufferException.

Modification:

Added isWritable and ensureWritable method overrides on ReadOnlyByteBufferBuf to indicate that it is never writable. Added tests for these methods.

Result:

Can successfully write ReadOnlyByteBufferBuf to a channel with an SslHandler (or any other handler which may attempt to write to the ByteBuf it receives).

f9604eeff5 Motivation: (#7848)
It is possible to create streams in the half-closed state where the
stream state doesn't reflect that the request headers have been sent by
the client or the server hasn't received the request headers. This
state isn't possible in the H2 spec as a half closed stream must have
either received a full request or have received the headers from a
pushed stream. In the current implementation, this can cause the stream
created as part of an h2c upgrade request to be in this invalid state
and result in the omission of RST frames as the client doesn't believe
it has sent the request to begin with.

Modification:

The `DefaultHttp2Connection.activate` method checks the state and
modifies the status of the request headers as appropriate.

Result:

Fixes #7847.

4cd39cc4b3 Filter DNS results so they only contain the expected type when multiple types are present. (#7875)
Motivation:

Currently, if a DNS server returns a non-preferred address type before the preferred one, then both will be returned as the result, and when only taking a single one, this usually ends up being the non-preferred type. However, the JDK requires lookups to only return the preferred type when possible to allow for backwards compatibility.

To allow a client to be able to resolve the appropriate address when running on a machine that does not support IPv6 but the DNS server returns IPv6 addresses before IPv4 addresses when querying.

Modification:

Filter the returned records to the expected type when both types are present.

Result:

Allows a client to run on a machine with IPv6 disabled even when a server returns both IPv4 and IPv6 results. Netty-based code can be a drop-in replacement for JDK-based code in such circumstances.

This PR filters results before returning them to respect JDK expectations.

Only reset readIsPending if outboundBuffer is not empty. (#7874)
Motivation:

Also check if the outboundBuffer is not empty before setting readInProgress to false again

0b690a991f Added IP_TRANSPARENT option for UDP (#7872)
Motivation:

This allows netty to operate in 'transparent proxy' mode for UDP, intercepting connections
to other addresses by means of Linux firewalling rules, as per

https://www.kernel.org/doc/Documentation/networking/tproxy.txt


Modification:

Add IP_TRANSPARENT option.

Result:

Allows setting and getting of the IP_TRANSPARENT option, which allows retrieval of the ultimate socket address originally requested.

a4146b706c Do not enforce arbitrary max header list size in HpackEncoder (#7853)
Motivation:

When connecting to an HTTP/2 server that did not set any value for the
SETTINGS_MAX_HEADER_LIST_SIZE in the settings frame, the netty client was
imposing an arbitrary maximum header list size of 8kB. There should be no need
for the client to enforce such a limit if the server has not specified any
limit. This caused an issue for a grpc-java client that needed to send a large
header to a server via an Envoy proxy server. The error condition is
demonstrated here: https://github.com/JLofgren/demo-grpc-java-bug-4284

Fixes grpc-java issue #4284 - https://github.com/grpc/grpc-java/issues/4284
and netty issue #7825 - https://github.com/netty/netty/issues/7825

Modifications:

In HpackEncoder use MAX_HEADER_LIST_SIZE as default maxHeader list size.

Result:

HpackEncoder will only enforce a max header list size if the server has
specified a limit in its settings frame.

81a7d1413b Makes EmptyByteBuf#hashCode and AbstractByteBuf#hashCode consistent (#7870)
Motivation:
The `AbstractByteBuf#equals` method doesn't take into account the
class of buffer instance. So the two buffers with different classes
must have the same `hashCode` values if `equals` method returns `true`.
But `EmptyByteBuf#hashCode` is not consistent with `#hashCode`
of the empty `AbstractByteBuf`, that is violates the contract and
can lead to errors.

Modifications:
Return `1` in `EmptyByteBuf#hashCode`.

Result:
Consistent behavior of `EmptyByteBuf#hashCode` and `AbstractByteBuf#hashCode`.

Motivation:
NPE in `CorsHandler` if a pre-flight request is done using an Origin header which is not allowed by any `CorsConfig` passed to the handler on creation.

Modifications:
During the pre-flight, check the `CorsConfig` for `null` and handle it correctly by not returning any access-control header

c58069f284 Better handling of streaming JSON data in JsonObjectDecoder (#7821)
Motivation:

When the JsonObjectDecoder determines that the incoming buffer had some data discarded, it resets the internal index to readerIndex and attempts to adjust the state which does not correctly work for streams of JSON objects.

Modifications:

Reset the internal index to the value considering the previous reads.

Result:

JsonObjectDecoder correctly handles streams of both JSON objects and arrays with no state adjustments or repeatable reads.
