/system/bin/su: No such file or directory about kernelsu

[tiann]

你装的是不是 32 位的应用

[shandongtlb]

貌似是system挂载只读导致的，可是刷了读写模块还不行

[shandongtlb]

你装的是不是 32 位的应用

你指的是ksu的APP32位吗，貌似只有64一个版本
其他终端类都是64的

[shandongtlb]

你装的是不是 32 位的应用

我专门看了一下，就算模块已经挂载读写，/system/bin/里面也没有su

[tiann]

su 文件本来就不存在。你直接运行 /system/bin/su 是什么结果？

not found

[shandongtlb]

换了几个APP，都一样的结果

[shandongtlb]

juicessh和termux 都不行

[fsxitutu]

juicessh和termux 都不行

如果你是使用termux的google play版本，请换回f-droid版本。实测google play版本在termux环境内无法识别kernelsu的su命令(failsafe环境可使用su)。

可是我得用nethunter的终端，不行，现在换回magisk了，先将就着

如果还想在用 ksu 的情况下正常使用 play 版 termux ，可以把你的 su 脚本 ($PREFIX/bin/su) 换成下面的代码

if [ -n "$LD_PRELOAD" ]; then
 unset LD_PRELOAD LD_LIBRARY_PATH
 exec /system/bin/sh $0 "$@"
fi
exec /system/bin/su "$@"

[bgaojin]

我遇到的问题 设置shell root以后，linux(5.15.0-107-generic)下打开终端 adb shell 输入su 提示/system/bin/su: 没有那个文件或目录
用的0.9.5版本，手机内核4.4 自己编译，其他app root正常。之前使用的是0.7.6版本 功能正常，升级0.9.5以后遇到这个问题,代码申请su一切正常

[kongle233]

我也遇见了同样的问题，经过我的测试,内核ksu版本大于等于9.4就会出现这个问题，目前尚未解决

JuiceSSH(com.sonelli.juicessh) version 3.2.2(Google Play Store) 看上去不会直接execve
edit: commit 815f4d0 可能漏hook了fstatat64？
edit2: hook点newfstatat 换成vfs_fstat(at)看上去会更好？这两个函数都在linux/fs.h里面且不是static。
