Utilize i.n.u.internal.ObjectUtil to assert Preconditions (transport*) (#11170) (#11181)
Motivation:

NullChecks resulting in a NullPointerException or IllegalArgumentException, numeric ranges (>0, >=0) checks, not empty strings/arrays checks must never be anonymous but with the parameter or variable name which is checked. They must be specific and should not be done with an "OR-Logic" (if a == null || b == null) throw new NullPointerEx.

Modifications:

* import static relevant checks
* Replace manual checks with ObjectUtil methods

Result:

All checks needed are done with ObjectUtil, some exception texts are improved.

Fixes #11170

Continue reading when the number of bytes is less then the configured… (#11089)
... number of bytes when using DatagramChannels

Motivation:

In our FixedRecvByteBufAllocator we dont continue to read if the number of bytes is less then what was configured. This is correct when using it for TCP but not when using it for UDP. When using UDP the number of bytes is the maximum of what we want to support but we often end up processing smaller datagrams in general. Because of this we should use contineReading(UncheckedBooleanSupplier) to determite if we should continue reading

Modifications:

- use contineReading(UncheckedBooleanSupplier) for DatagramChannels

Result:

Read more then once in the general case for DatagramChannels with the default config

Allow to configure the maximum number of message to write per eventloop (#11086)
Motivation:

Allow to configure the maximum number of messages to write per eventloop run. This can be useful to ensure we read data in a timely manner and not let writes dominate the CPU time. This is especially useful in protocols like QUIC where you need to read "fast enough" as otherwise you may not read the ACKs fast enough.

Modifications:

- Add new ChannelOption / config that allows to limit the number of messages to write per eventloop run.
- Respect this setting for DatagramChannels

Result:

Reduce the risk of having WRITES block the processing of other events in a timely manner

SslHandler flushing with TCP Fast Open fix (#11077)
Motivation:
SslHandler owns the responsibility to flush non-application data
(e.g. handshake, renegotiation, etc.) to the socket. However when
TCP Fast Open is supported but the client_hello cannot be written
in the SYN the client_hello may not always be flushed. SslHandler
may not wrap/flush previously written/flushed data in the event
it was not able to be wrapped due to NEED_UNWRAP state being
encountered in wrap (e.g. peer initiated renegotiation).

Modifications:
- SslHandler to flush in channelActive() if TFO is enabled and
  the client_hello cannot be written in the SYN.
- SslHandler to wrap application data after non-application data
  wrap and handshake status is FINISHED.
- SocketSslEchoTest only flushes when writes are done, and waits
  for the handshake to complete before writing.

Result:
SslHandler flushes handshake data for TFO, and previously flushed
application data after peer initiated renegotiation finishes.

Add tests verifying channel configure/initialisation order (#11050)
Motivation:
Channels need to have their configurations applied before we can call out to user-code via handlerAdded and initChannel.

Modification:
This adds tests for this behaviour, which already works correctly.

Result:
Better test coverage.

Add support for UDP_SEGMENT (GSO) when using sendmmsg (#11038)
Motivation:

For protocols like QUIC using UDP_SEGMENT (GSO) can help to reduce the
overhead quite a bit. We should support it.

Modifications:

- Add a SegmentedDatagramPacket which can be used to use UDP_SEGMENT
- Add unit test

Result:

Be able to make use of UDP_SEGMENT

TCP Fast Open for clients (#11006)
Support TCP Fast Open for clients and make SslHandler take advantage

Motivation:
- TCP Fast Open allow us to send a small amount of data along side the initial SYN packet when establishing a TCP connection.
- The TLS Client Hello packet is small enough to fit in there, and is also idempotent (another requirement for using TCP Fast Open), so if we can save a round-trip when establishing TLS connections when using TFO.

Modification:
- Add support for client-side TCP Fast Open for Epoll, and also lowers the Linux kernel version requirements to 3.6.
- When adding the SslHandler to a pipeline, if TCP Fast Open is enabled for the channel (and the channel is not already active) then start the handshake early by writing it to the outbound buffer.
- An important detail to note here, is that the outbound buffer is not flushed at this point, like it would for normal handshakes. The flushing happens later as part of establishing the TCP connection.

Result:
- It is now possible for clients (on epoll) to open connections with TCP Fast Open.
- The SslHandler automatically detects when this is the case, and now send its Client Hello message as part of the initial data in the TCP Fast Open flow when available, saving a round-trip when establishing TLS connections.

c735357bf2 Use Files.createTempFile(...) to ensure the file is created with proper permissions
Motivation:

File.createTempFile(String, String)` will create a temporary file in the system temporary directory if the 'java.io.tmpdir'. The permissions on that file utilize the umask. In a majority of cases, this means that the file that java creates has the permissions: `-rw-r--r--`, thus, any other local user on that system can read the contents of that file.
This can be a security concern if any sensitive data is stored in this file.

This was reported by Jonathan Leitschuh <jonathan.leitschuh@gmail.com> as a security problem.

Modifications:

Use Files.createTempFile(...) which will use safe-defaults when running on java 7 and later. If running on java 6 there isnt much we can do, which is fair enough as java 6 shouldnt be considered "safe" anyway.

Result:

Create temporary files with sane permissions by default.

Ensure we create a copy of the attributes and options when bootstrap a channel (#10965)
Motivation:

We need to ensure we copy the attributes and options when bootstrap the channel as otherwise we may change the underlying Entry.
This is similar to what was reported in https://github.com/netty/netty-incubator-codec-quic/issues/152.

Modifications:

- Do a copy and re-use methods
- Add unit tests

Result:

Don't affect attributes / options of channels that are already bootstrapped

Allow and skip null handlers when adding a vararg list of handlers (#10751)
Motivation:

Allowing null handlers allows for more convenient idioms in
conditionally adding handlers, e.g.,

ch.pipeline().addLast(
        new FooHandler(),
        condition ? new BarHandler() : null,
        new BazHandler()
);

Modifications:

* Change addFirst(..) and addLast(..) to skip null handlers, rather than
break or short-circuit.
* Add new unit tests.

Result:

* Makes addFirst(..) and addLast(..) behavior more consistent
* Resolves https://github.com/netty/netty/issues/10728

Make changes to prepare for io_uring incubator repository (#10741)
Motivation:

During the last few month we did develop an io_uring based transport which shows very promising performance numbers. To give it more time to bake we will develop it outside of netty in an "incubator" module which will make it clear to users what to expect and also allow us to seperate its release cycle. While the implementation of it is very self contained there are few small adjustments that need to be made in netty itself to allow us to reuse code.

Modifications:

- AbstractChannel: Add method which can be used when a write fails and remove final from one method
- IovArray: Allow to create an IovArray from a ByteBuf instance
- FileDescriptor: Allow to reuse mark close logic via sub-class

Result:

Be able to reuse netty core classes in io_uring incubator repository

Release message before notify promise (#10726)
Motivation:

We should preferable always release the message before we notify the promise. Thhis has a few advantages:

 - Release memory as soon as possible
 - Listeners observe the "more correct" reference count

Modifications:

Release message before fail the promises

Result:

Faster releasing of resources. This came up in https://github.com/netty/netty/issues/10723

Fix native image build on modern GraalVM versions for the cases when the program uses netty-dns (#10630)
Motivation:

Since GraalVM version 19.3.0, instances of java.net.InetAddress (and its subclasses Inet4Address and Inet6Address) are not allowed in native image heap (that is, they cannot be stored in static fields of classes initialized at build time or be reachable through static fields of such classes). When building a native image, it makes sense to initialize at build time as many classes as possible.
But some fields of some classes in Netty (for example, NetUtil.LOCALHOST4) contain InetAddress instances. If a program is using code path that makes it possible to reach such fields at build time initialization, it becomes impossible to build a native image initializing core Netty classes initialized at runtime. An example of such a program is a client that uses netty-dns.

Modifications:

- Add netty-testsuite-native-image-client Maven module to test that such an example program can be built after the corresponding fixes
- Add native-image.properties to resolver-dns module to move initialization of some classes to runtime (some of them are parsing configuration during initialization, so it makes no sense to initialize them at build time; for others, it's needed to avoid InetAddress reachability at build time)
- Add substitutions for NetUtil.LOCALHOST4, NetUtil.LOCALHOST6 and NetUtil.LOCALHOST to overcome the InetAddress-related prohibition
- Extract some initialization code from NetUtil to NetUtilInitializations to allow it to be used by the substitutions

Result:

A client program using netty-dns with --initialize-at-build-time=io.netty builds successfully
