setsockopt IPV6_V6ONLY does not work

[anders]

# python
>>> import socket
>>> s = socket.socket(socket.AF_INET6, socket.SOCK_STREAM, 0)
>>> s.setsockopt(socket.IPPROTO_IPV6, socket.IPV6_V6ONLY, 1)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.7/socket.py", line 224, in meth
    return getattr(self._sock,name)(*args)
socket.error: [Errno 22] Invalid argument

Seems the same issue as #68

@anders Can confirm from our side that the socket option IPPROTO_IPV6\IPV6_V6ONLY is not yet implemented. We have opened a bug on our side to track this. No ETA at this time.

Looks to be fixed in 14361:

do this
int flag = 1;
int ret = setsockopt(sock_fd, IPPROTO_IPV6, IPV6_V6ONLY, &flag, sizeof(flag));
