Hi Justus,

System: Linux:4.9.11-1-ARCH:#1 SMP PREEMPT Sun Feb 19 13:45:52 UTC 2017
sizeof addr.sun_path: 108
Running test with strlen (cwd): 22, name: '/tmp/test-unix-sockets/socket'
  getsockname returned '/tmp/test-unix-sockets/socket', addrlen: 32
Running test with strlen (cwd): 22, name: 'socket'
  getsockname returned 'socket', addrlen: 9
Running test with strlen (cwd): 130, name: 'socket'
  getsockname returned 'socket', addrlen: 9
Running test with strlen (cwd): 1102, name: 'socket'
  getsockname returned 'socket', addrlen: 9

Cheers,
Jochen
