在init.AAA.rc里面添加了一个脚本启动的服务:
service AAA /vendor/bin/sh /vendor/etc/AAA_spec.sh
user root
group root
disabled
oneshot
on post-fs-data
start AAA
在系统启动时通过dmesg | grep init查看发现出现:Service AAA does not have a SELinux domain defined
解决方法:
1.在devices/vendorxxx/sepolicy/common/目录下新增AAA.te文件,内容如下:
type AAA, domain;
type AAA_exec, exec_type, vendor_file_type,file_type;
init_daemon_domain(AAA)
allow AAA vendor_shell_exec:file { entrypoint };
2.在devices/vendorxxx/sepolicy/Android.mk文件中添加:
BOARD_SEPOLICY_DIRS += devices/vendorxxx/sepolicy/common/
3.在devices/vendorxxx/sepolicy/common/file_contexts中添加:
##add for AAA file permission##
/(vendor|system/vendor)/etc/AAA_spec\.sh u:object_r:AAA_exec:s0
4.在init.AAA.rc里面对应的service里面添加:
service AAA /vendor/bin/sh /vendor/etc/AAA_spec.sh
user root
group root
disabled
oneshot
seclabel u:r:carrier_switcher:s0
5.编译并烧录bootimage,若编译报错注意解决neverallow冲突
6.系统起来时如发现avc则逐一添加allow策略语句
