Hi net-devs,
I've got a problem on AIX operating system when IPv6 is enabled,which
can be easily reproduced by attached test case NetworkInterfaceTest.java.
On AIX paltform, the /proc file system behaves differently from Linux,
so we cannot just read required lines from /proc/net/if_inet6 but to
call ioctl to get needed information. A patch is available for OpenJDK8
code base, see attachment patch.diff.
Is anybody interested in this topic?
I'm quite aware of the fact that so far there's no publicly available
building scripts for OpenJDK8 on AIX operating system, but before
everything settles down, is anybody willing to review the patch? any
ideas about how to integrate it?
Best regards!
Hi Jonathan - can you add a copyright header to the testcase and see if
you can make the testcase fit into a jtreg test format?
Hi Steve,
Thanks for your suggestion.
I've updated the test case to fit into a jtreg format, see the
attachment NetworkInterfaceTest.java.
Cool - at a quick glance it looks fine - except your're missing the IBM
attribution comment. I'll send you the details.
- Jonathan
Thanks Steve, I've updated the test case and patch, see the attachments.
I've added IBM portions copyright comment to both headers.
