相关的issue是[CRITICAL] Don't trust GCD to give accurate UDP packet sizes.#222。作者认为dispatch_source_get_data()返回的数据是不可靠的,如果数据过大它会默不作声的对你的数据做一个截断,大小是9216。所以他pr上去我发现的maxSize那一段的代码。我去Apple那里查了一下dispatch_source_get_data()的文档...

默认情况下,Windows Server 2008 和 Windows Vista 将首先尝试使用 TCP 进行 Kerberos,因为 MaxPacketSize 默认值现在为 0。 你仍然可以使用 MaxPacketSize 注册表值来替代该行为。UDP 数据包大小的限制可能会导致域登录时出现以下错误消息:事件日志错误 5719 源NETLOGON 没有适用于域 域的Windows NT 或 Windows ...
