RK3399 Android 添加开机启动shell脚本

按需求建了一个开机启动的脚本

1.建立myshell.sh脚本 ,放在device/rockchip/rk3399内

#!/system/bin/sh

//启动之后一直循环
while true;do 
        //对应操作
        sleep 1
   
done     
           

2.建立对应的myshell.te文件,放在device/rockchip/common/sepolicy内

device/rockchip/common/sepolicy/myshell.te 
type myshell, domain;
type myshell_exec, exec_type, file_type;


init_daemon_domain(myshell)

//添加对应功能的授权
allow myshell init_tmpfs:file create_file_perms;
allow myshell self:capability { dac_override net_admin net_raw setgid setuid };
allow myshell device:dir { open read };
allow myshell shell:lnk_file { read };
allow myshell rootfs:lnk_file { getattr };
allow myshell socket_device:sock_file { write };

allow myshell shell_exec:file { getattr read};
allow myshell fuse:dir { search write add_name getattr};
allow myshell fuse:file { create write open getattr};
allow myshell system_file:file { execute_no_trans};
           

avc权限添加 可参考：https://blog.csdn.net/tq501501/article/details/103556837

3. 添加到 system/core/rootdir/init.rc

service myshell /system/bin/myshell.sh
     user root
     group root
     disabled

#在init.rc中启动该服务
on property:sys.boot_completed=1
     start myshell

chown root shell /system/bin/myshell.sh
chmod 0550 /system/bin/myshell.sh
           

4.修改device/rockchip/common/sepolicy/file_contexts

#add for glgps
 /system/bin/glgps    u:object_r:gpsd_exec:s0
+/system/bin/myshell.sh u:object_r:myshell_exec:s0
           

5.修改device/rockchip/rk3399/rk3399.mk  //添加脚本到板子的system/bin内

PRODUCT_COPY_FILES += vendor/rockchip/common/phone/etc/apns-full-conf.xml:system/etc/apns-conf.xml
 PRODUCT_COPY_FILES += vendor/rockchip/common/phone/etc/spn-conf.xml:system/etc/spn-conf.xml
+PRODUCT_COPY_FILES += device/rockchip/rk3399/myshell.sh:system/bin/myshell.sh
           

6. 修改system/sepolicy/file_contexts

添加以下(注意此处不要加.sh)

/system/bin/myshell             u:object_r:myshell_exec:s0
