在提交之前，请确认

我已经尝试搜索过 Issue ，但没有找到相关问题。
我正在使用最新的 mosdns 版本(或者最新的 commit)，问题依旧存在。
我仔细看过 wiki 后仍然无法自行解决该问题。
我非常确定这是 mosdns 核心的问题。(如果是通过第三方衍生软件使用 mosdns 核心，不确定问题源头时，请先向衍生软件开发者提交问题。)

mosdns 版本

v5.3.1

操作系统

hiboy汉化版padavan 2023_7-1

Bug 描述和复现步骤

监听 UDP 端口失败，进而启动失败。（mosdns报错，自动退出）
v5.3.0 同样报错
v5.2.1 报其它错
v5.1.3 一切正常

v5.2.1 日志打印有大量的
ERROR udp_server failed to get dst address from oob {"error": "control msg does not have dst address"}

去掉0.0.0.0呢？

Irine Sistiana · Answer 4 · Tue Nov 07 2023 08:29:23 GMT+0800 (China Standard Time)

去掉0.0.0.0呢？

不行。他这有两个问题。

failed to create socket, listen udp 0.0.0.0:5553: protocol not available

这个是内核太老了。mosdns 最近加了一些优化，需要 3.9+

Linux 3.9 was released on April 28, 2013

3.9 内核也已经十年了。

control msg does not have dst address

和 #750 相似。

去掉0.0.0.0呢？

去掉 "0.0.0.0" 、换成 "127.0.0.1" 都不行

这几天在刷机弄OPENWRT，刚好也出现过未运行的情况。MT7621平台，刷机包定制的带MOSDNS，设置后无法启动。一次是联网更新了一下MOSDNS后正常（刷机包3天前定制的，版本显示是5.3.1的最新，但是联网查库显示还能更新），今天上午重新定制刷机包，集成最新版MOSDNS后设置参数显示未运行，手动安装了Goip的两个包后仍未运行，把路由器重启后显示已运行。
不知道这些情况是不是有关连。

内核版本Linux OpenWrt 5.15.137 也存在同样的问题
