Failing tests: * testFDPassSeparateMinSpace (test.test_socket.RecvmsgSCMRightsStreamTest) * testFDPassSeparate (test.test_socket.RecvmsgIntoSCMRightsStreamTest) * testFDPassSeparateMinSpace (test.test_socket.RecvmsgIntoSCMRightsStreamTest) * testFDPassSeparate (test.test_socket.RecvmsgSCMRightsStreamTest) * testFDPassSeparateMinSpace (test.test_socket.RecvmsgSCMRightsStreamTest) * testFDPassSeparate (test.test_socket.RecvmsgIntoSCMRightsStreamTest) * testFDPassSeparateMinSpace (test.test_socket.RecvmsgIntoSCMRightsStreamTest) It looks like the failure come from code like: self.sendmsgToServer([MSG], [(socket.SOL_SOCKET, socket.SCM_RIGHTS, array.array("i", [fd0])), and self.doRecvmsg(self.serv_sock, len(MSG), socket.CMSG_SPACE(SIZEOF_INT) + socket.CMSG_LEN(SIZEOF_INT)), In clear, there are errors on tests sending file descriptors through UNIX sockets. So this issue is a duplicate of #20718, but we may keep this one for AIX, and #20718 for OpenBSD. It looks possible to send a file descriptor between processes but using a pipe with I_SENDFD and I_RECVFD ioctl.

Failing tests:

It looks like the failure come from code like:

    self.sendmsgToServer([MSG], [(socket.SOL_SOCKET,
                                  socket.SCM_RIGHTS,
                                  array.array("i", [fd0])),

and

    self.doRecvmsg(self.serv_sock, len(MSG),
                   socket.CMSG_SPACE(SIZEOF_INT) + socket.CMSG_LEN(SIZEOF_INT)),

In clear, there are errors on tests sending file descriptors through UNIX sockets. So this issue is a duplicate of #20718, but we may keep this one for AIX, and #20718 for OpenBSD.
