在安卓中进行root。程序执行错误“权限被拒绝”
我程序的可执行文件和库已安装在目录中 bindir =/data/app/ru.testapp/lib/x86_64/，此目录已在SELINUX中执行权限。 该程序的其余部分（附加文件）安装在EnviroMent = /data/user/0/ru.testapp/files/files/enviroment Directory中： bin dev et et lib proc root rut sys系统USR var。 Enviroment目录在Selinux中没有执行权利。 我正在尝试使用proot运行该应用程序：
proot\
--link2symlink\
-w /root\
-r $Environment \
-b $BinDir:/bin\
-b $BinDir:/lib \
-b /sys\
-b /system/ \
-b /apex\
-b /proc/ \
-b /dev\
/bin/test
正如您可以看到我“ bind” $ bindir到$ enviroment/lib和$ enviroment/bin。在这种情况下，执行SELinux的权利在这些目录中丢失了，我遇到了“允许拒绝”错误。绝对没有其他错误，因为在SU下，整个机制起作用。
在这种情况下可以做什么？
The executables and libraries of my program are installed in the directory
BinDir=/data/app/ru.testapp/lib/x86_64/, this directory has execute permission in SELinux.
The rest of the program (additional files) is installed in the Enviroment= /data/user/0/ru.testapp/files/enviroment directory:
bin dev etc lib proc root run sys system usr var.
The Enviroment directory does not have execute rights in SELinux.
I am trying to run the application using proot:
proot\
--link2symlink\
-w /root\
-r $Environment \
-b $BinDir:/bin\
-b $BinDir:/lib \
-b /sys\
-b /system/ \
-b /apex\
-b /proc/ \
-b /dev\
/bin/test
As you can see I "bind" $BinDir to $Enviroment/lib and $Enviroment/bin. In this case, the right to execute SELinux is lost in these directories and I get a "permisiion denied" error. There are definitely no other errors, since under su this whole mechanism works.
What can be done in this situation?

我的问题是通过使用 PROOT_UNBUNDLE_LOADER 环境变量集构建 proot 来解决的，以便加载程序位于 SELinux 允许执行的 $BinDir 位置。一般来说，错误出在原始加载程序上。

My problem was solved by building proot with the PROOT_UNBUNDLE_LOADER environment variable set so that the loader is in the $BinDir location where SELinux allows execution. In general, the error was with the proot loader.
