The __convert_scm_timestamps only updates the control message last pointer for SOL_SOCKET type, so if the message control buffer contains multiple ancillary message types the converted timestamp one might overwrite a valid message. The test checks if the extra ancillary space is correctly handled by recvmsg/recvmmsg, where if there is no extra space for the 64-bit time_t converted message the control buffer should be marked with MSG_TRUNC. It also check if recvmsg/recvmmsg handle correctly multiple ancillary data. Checked on x86_64-linux and on i686-linux-gnu on both 5.11 and 4.15 kernel.
