Hi, I have the impression that you are leaking the accepted and
connector socket from previous tests, can you please check?

I believe the comment should be "family set\n", right? But actually
your change suggests that the whole structure should be left
unmodified so I believe it's better to test the whole structure to
ensure the change is fully tested. You could add ss_empty variable,
memset it to zero and memcmp both.

Please fix the subject ;-)

Best wishes,
Bruno
