187bdc2562 Add epoll aarch64 maven config and Dockerfile (#9804)
Motivation:

`transport-native-epoll` doesn't have ARM release package. 

Modification:

This PR added cross compile profile for epoll. Then we can easily build aarch64 package on X86 machine. 

Result:
Fixes #8279

154e40bcea Fix the transport-native-unix-common build on FreeBSD (#9814)
Motivation:

Modern versions of FreeBSD define IP_RECVORIGDSTADDR, but don't define
SOL_IP.  This causes the build to fail.

Modifications:

The equivalent to SOL_IP on FreeBSD is IPPROTO_IP.  Define SOL_IP as that
if SOL_IP is not defined and IPPROTO_IP is.

Result:

This allows a successful build on FreeBSD

d4d81ac94c 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.

3fbec92221 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.

Add *ReceiveBufferSize / *SendBufferSize methods to DomainSocketChannelConfig interface (#9602)
Motivation:

aebe206 added support for using a ChannelOption to set / get Buffer sizes but did not add the methods to the DomainSocketChannelConfig interface itself (due not be able to break the API)

Modifications:

Add methods to interface (as this is a next major release)

Result:

Easier access to configure these buffer sizes

15eef2425a 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

19a12fba4c 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

d57a5f5d4f 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

b3e6e41384 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.

8910d62544 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

33d1a91083 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.

ed61e5f543 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.

135c33b478 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.

2689f28cb7 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://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.

5618229203 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.

fa8f967852 netty_unix_socket free nettyClassName after using it
Motivation:
netty_unix_socket attempts to use nettyClassName in an error message, but previously freed the memory. We should wait to free the memory until after we use it.

Modifications:
- Free nettyClassName after using it in snprintf

Result:
More useful error message.

Fix support for shading native libraries which was broken in b818852cdb. (#8091)
Motivation:

b818852cdb broke support for shading the native libraries in netty as it missed to respect the package prefix that is used when shading.

Modifications:

Correctly respect package prefix for constructor argument and include the used classname when logging that we could not find the constructor.

Result:

Be able to shade native libraries of netty again.

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.

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.

8189399e9d Ignore EINTR on close(...) as there is nothing sane we can do.
Motivation:

If close(...) reports EINTR there is nothing sane we can do so it makes no sense to even report it. See also:

https://github.com/apple/swift-nio/pull/217

Modifications:

Just ignore EINTR when calling close(...)

Result:

Less noise in the logs.

f6251c8256 IovArray.add(...) should check if buffer has memory address.
Motivation:

We currently not check if the buffer has a memory address and just assume this is the case if the nioBufferCount() == 1.

Modifications:

- Check hasMemoryAddress() before trying to access it.
- Add unit case.

Result:

More correct and robust code. Related to [#7752].
