8207404: MulticastSocket tests failing on Aix

Hi Goetz,
I disabled IPv6 on my xLinux box and the MulticastSocket tests pass, as
they detected that IPv6 is not enabled and then didnt try and set the IPv6
options.
I am currently unable to disable IPv6 on my AIX box to test this but would
assume it would also work as the code checks to see whether IPv6 is
enabled and doesnt try and set the IPV6 options.
It seems the issue with the tests failing seems to be, if IPv6 is enabled
but the interface doesn't have an IPv6 address associated with it, as in
your case here:
bash-4.3$ ifconfig -a
en0:
flags=1e084863,480<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST,GROUPRT,64BIT,CHECKSUM_OFFLOAD(ACTIVE),CHAIN>
inet 10.xx.xxx.xxx netmask 0xfffffe00 broadcast 10.xx.xxx.xxx
tcp_sendspace 262144 tcp_recvspace 262144 rfc1323 1
lo0:
flags=e08084b,c0<UP,BROADCAST,LOOPBACK,RUNNING,SIMPLEX,MULTICAST,GROUPRT,64BIT,LARGESEND,CHAIN>
inet 127.x.x.x netmask 0xff000000 broadcast 127.xxx.xxx.xxx
inet6 ::1%1/0
tcp_sendspace 131072 tcp_recvspace 131072 rfc1323 1
where you can see that the en0 interface has an inet address associated
but doesnt have an inet6 address associated.
I can see that IPv6 is enabled as the lo0 interface has an inet6 address
(pointing to localhost)
As I stated below, my AIX system was configured in a similar way to yours
and the tests failed. When I was able to add an inet6 address to en0,
everything works correctly.
NOTE: Not sure this was correct but I ran 'sudo autoconf6' which seemed to
add the inet6 address to my en0 interface. After that all tests worked.
So I think the tests are working as expected, but the AIX system is not
configured correctly, but I would like someone else to confirm this.
Thanks

i Steve,
thanks for looking at this issue.
> Should these tests work without having IPV6 configured on the interface?
In general, tests should not show errors if a system does not meet
the requirements for the test. In such cases the test should
be skipped somehow. Maybe only a test fix is needed.
Can you check on a non-aix machine without ipv6 whether the test
passes?

This is our test machine:
bash-4.3$ ifconfig -a
en0:
flags=1e084863,480<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST,GROUPRT,64BIT,CHECKSUM_OFFLOAD(ACTIVE),CHAIN>
inet 10.xx.xxx.xxx netmask 0xfffffe00 broadcast 10.xx.xxx.xxx
tcp_sendspace 262144 tcp_recvspace 262144 rfc1323 1
lo0:
flags=e08084b,c0<UP,BROADCAST,LOOPBACK,RUNNING,SIMPLEX,MULTICAST,GROUPRT,64BIT,LARGESEND,CHAIN>
inet 127.x.x.x netmask 0xff000000 broadcast 127.xxx.xxx.xxx
inet6 ::1%1/0
tcp_sendspace 131072 tcp_recvspace 131072 rfc1323 1
I think this message should be posted to core-libs-dev, too. That's also
the list where a potential fix needs to be reviewed.
Best regards,
Goetz.
