3add35fe82
Motivation:
394a1b3485 introduced a hard dependency on GLIBC 2.12 which was not the case before. This had the effect of not be able to use the native epoll transports on platforms which ship with earlier versions of GLIBC.
To make things a backward compatible as possible we should not introduce such changes in a bugfix release.
Special thanks to @weissi with all the help to fix this.
Modifications:
- Use syscalls directly to remove dependency on GLIBC 2.12
- Make code consistent that needs newer GLIBC versions
- Adjust scattering read test to only run if recvmmsg syscall is supported
- Cleanup pom.xml as some stuff is not needed anymore after using syscalls.
Result:
Fixes https://github.com/netty/netty/issues/9758.

Netty must be released from RHEL 6.8 x86_64 or compatible so that:
|
|
|
|
1) we ship x86_64 version of epoll transport officially, and
|
|
2) we ensure the ABI compatibility with older GLIBC versions.
|
|
|
|
The shared library built on a distribution with newer GLIBC
|

will not run on older distributions.
