描述

DNS规则中若存在多个地址筛选规则，则会出现死循环产生大量日志，最终可能导致崩溃。

重现方式

使用以下配置可复现：

            "store_rdrc": true,
            "rdrc_timeout": "1h"
        }
    }
}

使用Termux通过命令dig +noedns a www.baidu.com查询dns，预期结果应该是返回fakeip，但实际进入死循环，无法返回结果。在1.11.0-beta.19也可复现，但1.10.6稳定版无法复现，暂不知道问题引入版本，经测试在windows平台命令行工具和安卓图形客户端均有此问题。

支持我们

完整性要求

  • 我保证阅读了文档，了解所有我编写的配置文件项的含义，而不是大量堆砌看似有用的选项或默认值。
  • 我保证提供了可以在本地重现该问题的服务器、客户端配置文件与流程，而不是一个脱敏的复杂客户端配置文件。
  • 我保证提供了可用于重现我报告的错误的最简配置，而不是依赖远程服务器、TUN、图形界面客户端或者其他闭源软件。
  • 我保证提供了完整的配置文件与日志，而不是出于对自身智力的自信而仅提供了部分认为有用的部分。
