排查 logcat read failure 问题
排查 logcat read failure 问题
问题表现
通过 Android Studio 只能安装不能 debug 程序，安装上后会提示 lost connect 错误，盒子这边由等待 debugger 变成闪退。在分析问题时尝试通过 adb logcat 获取日志，发现 logcat 读取失败：logcat read failure。下面是分析这个问题的记录，最终没能解决这个问题。
排查过程
- 查看 logd 日志守护进程
1
2
p291_iptv:/ # ps -A | grep logd
1|p291_iptv:/ #
发现 logd 进程压根没有启动。
- 在系统内核日志中查找与 “logd” 相关的信息

1|p291_iptv:/ # dmesg | grep -i logd
[ 1.843887] init: Parsing file /system/etc/init/logd.rc...
[ 4.312622] logd: failed to set CAP_SETGID, CAP_SYSLOG or CAP_AUDIT_CONTROL (1)
[ 4.678944] logd: logd.daemon: failed to set AID_SYSTEM AID_PACKAGE_INFO groups
启动失败了：failed to set AID_SYSTEM AID_PACKAGE_INFO groups，这个错误通常是用户权限问题
- 查看 logd 的权限，所有者，所属组，SELinux上下文等信息

ls -lZ /system/bin/logd
-r-xr-x--- 1 logd logd u:object_r:logd_exec:s0 131800 2025-05-17 15:09 /system/bin/logd
- 查看日志目录，发现没有，及时创建也无济于事

可以看到 setuid32(1036) = -1 EPERM (Operation not permitted) 这个错误，切换uid时权限不够，因为我这个系统是三方定制的，经过阉割的，并且开启了 root 权限。
- 修改 /system/etc/init/logd.rc 为 root用户

没有用，还是报 setuid32(1036) 的错误，重启系统也没用。
结论
网上搜了下，把问题指向了 rom 和 root，我这个盒子也是网上定制的系统，懒得折腾了：https://blog.k-res.net/archives/2829.html
