Release 37 无法在openwrt master X64下自动启动
问题现象
Release 37 无法在openwrt master X64下自动启动
需要手动启动才能正常启动
运行环境
-
固件型号
openwrt master X64 kernel 5.10.135 -
运营商
-
smartdns来源以及版本 官方github编译 Release 37
-
涉及的配置(注意去除个人相关信息)
重现步骤
-
上游DNS配置。
-
访问的域名。
信息收集
- 将/var/log/smrtdns.log日志作为附件上传(注意去除个人相关信息)。
- 如进程异常，请将coredump功能开启，上传coredump信息文件，同时上传配套的smartdns进程文件。
在自定义界面，开启设置->自定义设置->生成coredump配置，重现问题后提交coredump文件 coredump文件在/tmp目录下
特地去下载了个
固件版本 | OpenWrt SNAPSHOT r20256-23c77384f3 / LuCI Master git-22.213.35850-abd9125 内核版本 | 5.10.135
试了一下自动启动一切正常。 然后突然想起来一件事：
2022.07.29-2755310930 Pre-release !重要 增加参数 response-mode: first-ping, fastest-ip, fastest-response 注意：与之前参数配置 response-mode whole-response 不兼容
如果你是从7月26日及更早版本升级过来且有配置 response-mode whole-response，则升级后程序不启动

我配置了 speed-check-mode tcp:443,tcp:80 force-AAAA-SOA yes max-reply-ip-num 1 force-qtype-SOA 65 response-mode fastest-ip
试试看是不是还可以启动
重启一下系统 发现系统日志有三处异常 不知道有用没

我是将smartdns编译到固件里面的 对比了一下固件里面的/etc/init.d/smartdns和源码中的不一样
