After some failures in AMD64 FreeBSD CURRENT Debug 3.x buildbots regarding tests in test_multiprocessing_spawn and after examining similar failures in test_socket, some errors in the calculation of ancillary data buffers were found in multiprocessing.reduction. CMSG_LEN() can often be used as the buffer size for recvmsg() to receive a single item of ancillary data, but RFC 3542 requires portable applications to use CMSG_SPACE() and thus include space for padding, even when the item will be the last in the buffer. The failures we experience are due to the usage of CMSG_LEN() instead of CMSG_SPACE(). (cherry picked from commit 077061a7b24917aaf31057885c69919c5a553c88) Co-authored-by: Pablo Galindo <Pablogsal@gmail.com>
