Introduce MacOSDnsServerAddressStreamProvider which correctly detect all nameserver configuration on MacOS (#9161)
Motivation:

On MacOS it is not really good enough to check /etc/resolv.conf to determine the nameservers to use. We should retrieve the nameservers using the same way as mDNSResponser and chromium does by doing a JNI call.

Modifications:

Add MacOSDnsServerAddressStreamProvider and testcase

Result:

Use correct nameservers by default on MacOS.

ed142442a4 Enable Netty on a big endian platform
Motivation:

We would like to enable Netty also on a big endian platform such as
s390_64. We need to fix a function which assumes that the target
platform is little endian.

Modifications:

Modify netty_unix_socket_accept() to write an address length as jbyte
instead of jsize.

Result:

Netty can be enabled on a big endian platform.

Cleanup JNI code to always correctly free memory when loading fails and also correctly respect out of memory in all cases (#9596)
Motivation:

At the moment we not consistently (and also not correctly) free allocated native memory in all cases during loading the JNI library. This can lead to native memory leaks in the unlikely case of failure while trying to load the library.

Beside this we also not always correctly handle the case when a new java object can not be created in native code because of out of memory.

Modification:

- Copy some macros from netty-tcnative to be able to handle errors in a more easy fashion
- Correctly account for New* functions to return NULL
- Share code

Result:

More robust and clean JNI code

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

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.

Use byte[] to create DatagramSocketAddress and so reduce overhead (#9516)
Motivation:

At the moment we use the String representation of the IP to create the DatagramSocketAddress. This is not for free and we should better use the byte[] directly to reduce the overhead of parsing the String (and creating it in the first place)

Modifications:

Directly use byte[] as input for the DatagramSocketAddress

Result:

Less overhead when using Datagrams with native transports

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.

Only use static Exception instances when we can ensure addSuppressed … (#9152)
Motivation:

OOME is occurred by increasing suppressedExceptions because other libraries call Throwable#addSuppressed. As we have no control over what other libraries do we need to ensure this can not lead to OOME.

Modifications:

Only use static instances of the Exceptions if we can either dissable addSuppressed or we run on java6.

Result:

Not possible to OOME because of addSuppressed. Fixes https://github.com/netty/netty/issues/9151.

ac023da16d Correctly handle overflow in Native.kevent(...) when EINTR is detected (#9024)
Motivation:
When kevent(...) returns with EINTR we do not correctly decrement the timespec
structure contents to account for the time duration. This may lead to negative
values for tv_nsec which will result in an EINVAL and raise an IOException to
the event loop selection loop.

Modifications:
Correctly calculate new timeoutTs when EINTR is detected

Result:
Fixes #9013.

Do not use GetPrimitiveArrayCritical(...) due multiple not-fixed bugs… (#8921)
* Do not use GetPrimitiveArrayCritical(...) due multiple not-fixed bugs related to GCLocker

Motivation:

GetPrimitiveArrayCritical(...) may cause multiple not-fixed bugs related to the GCLocker while there is little gain for our use-case. We should just use GetByteArrayRegion(...) and copy into a small on-stack buffer.

See also:

- https://shipilev.net/jvm/anatomy-quarks/9-jni-critical-gclocker/#_g1
- https://bugs.openjdk.java.net/browse/JDK-8048556
- https://bugs.openjdk.java.net/browse/JDK-8057573
- https://bugs.openjdk.java.net/browse/JDK-8057586

Special thanks to @jayv @shipilev @apangin for the pointers.

Modifications:

Replace GetPrimitiveArrayCritical(...) with GetByteArrayRegion(...)

Result:

Less risks hitting GCLocker related bugs.

a33200ca38 use checkPositive/checkPositiveOrZero (#8803)
Motivation:

We have a utility method to check for > 0 and >0 arguments. We should use it.

Modification:

use checkPositive/checkPositiveOrZero instead of if statement.

Result:

Re-use utility method.

5df235c083 Correcting Maven Dependencies (#8622)
Motivation:

Most of the maven modules do not explicitly declare their
dependencies and rely on transitivity, which is not always correct.

Modifications:

For all maven modules, add all of their dependencies to pom.xml

Result:

All of the (essentially non-transitive) depepdencies of the modules are explicitly declared in pom.xml

Allow to use native transports when sun.misc.Unsafe is not present on… (#8231)
* Allow to use native transports when sun.misc.Unsafe is not present on the system

Motivation:

We should be able to use the native transports (epoll / kqueue) even when sun.misc.Unsafe is not present on the system. This is especially important as Java11 will be released soon and does not allow access to it by default.

Modifications:

- Correctly disable usage of sun.misc.Unsafe when -PnoUnsafe is used while running the build
- Correctly increment metric when UnpooledDirectByteBuf is allocated. This was uncovered once -PnoUnsafe usage was fixed.
- Implement fallbacks in all our native transport code for when sun.misc.Unsafe is not present.

Result:

Fixes https://github.com/netty/netty/issues/8229.

Ensure multiple shaded version of the same netty artifact can be loaded as long as the shaded prefix is different (#8207)
Motivation:

We should support to load multiple shaded versions of the same netty artifact as netty is often used in multiple dependencies.

This is related to https://github.com/netty/netty/issues/7272.

Modifications:

- Use -fvisibility=hidden when compiling and use JNIEXPORT for things we really want to have exported
- Ensure fields are declared as static so these are not exported
- Adjust testsuite-shading to use install_name_tool on MacOS to change the id of the lib. Otherwise the wrong may be used.

Result:

Be able to use multiple shaded versions of the same netty artifact.
