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
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.
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.

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
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
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
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.
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
Motivation:
We should not only include the java source files but also the c source file in our source jars.
Modifications:
Add files from src/main/c as well
Result:
Fixes https://github.com/netty/netty/issues/9494
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.

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.
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.
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.
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
