Description: When binding a unix socket to an empty address on Linux, the socket is automatically bound to an available address in the abstract namespace. >>> s = socket.socket(socket.AF_UNIX, socket.SOCK_STREAM) >>> s.bind("") >>> s.getsockname() b'\x0075499' Since python 3.9, the socket is bound to the one address: >>> s.getsockname() b'\x00' And trying to bind multiple sockets will fail with: Traceback (most recent call last): File "/home/nsoffer/src/cpython/Lib/test/test_socket.py", line 5553, in testAutobind s2.bind("") OSError: [Errno 98] Address already in use Added 2 tests: Auto binding empty address on Linux Failing to bind an empty address on other platforms Fixes f6b3a07 (bpo-44493: Add missing terminated NUL in sockaddr_un's length (GH-26866) (cherry picked from commit c22f134) Co-authored-by: Nir Soffer nsoffer@redhat.com Issue: gh-94821
