我正在尝试使用新守护程序构建 AOSP 9，但 SELinux 不允许。
我的 sierra_config_ip.te 有这个文件的开头:
type sierra_config_ip, domain;
permissive sierra_config_ip;
type sierra_config_ip_exec, exec_type, file_type;
init_daemon_domain(sierra_config_ip)
我的 file_contexts 是:
/(vendor|system/vendor)/bin/init.config.ip u:object_r:sierra_config_ip_exec:s0
我的 init.rc 是:
service sierra_config_ip /vendor/bin/init.config.ip
class main
user root
group radio cache inet misc dhcp
capabilities BLOCK_SUSPEND NET_ADMIN NET_RAW
disabled
oneshot
但我总是收到以下错误:

Error while expanding policy
我不知道为什么不起作用，我按照此处其他主题中描述的步骤操作，例如 this one 。有人可以帮我弄这个吗？
除此之外，我尝试禁用 SELinux 以最终能够构建 Android。为了做到这一点，我把它
enforcing=0 androidboot.selinux=disabled
在 BoardConfig.mk 中的 BOARD_KERNEL_CMDLINE 中，但之前已构建策略并且错误再次发生!
我还尝试将 -sierra_config_ip 放在 domain.te 中:
full_treble_only(`
# Do not allow vendor components to execute files from system
# except for the ones whitelist here.
neverallow {
domain
-coredomain
-appdomain
-vendor_executes_system_violators
-vendor_init
-evs_domain
-sierra_config_ip
} {
exec_type
-vendor_file_type
-crash_dump_exec
-netutils_wrapper_exec
}:file { entrypoint execute execute_no_trans };
')
但我收到以下错误:
system/sepolicy/public/domain.te:1005:ERROR 'unknown type sierra_config_ip' at token ';' on line 11251:
#line 1005
}:file { entrypoint execute execute_no_trans };
最佳答案
需要在device/fsl/XXX/XXX/BoardConfig.mk中添加以下“BOARD_KERNEL_CMDLINE += androidboot.selinux=permissive”
更完整的例子:
# Kernel
BOARD_KERNEL_BASE := 0x80000000
BOARD_KERNEL_CMDLINE := console=null androidboot.hardware=qcom msm_rtb.filter=0x237 ehci-hcd.park=3
BOARD_KERNEL_CMDLINE += lpm_levels.sleep_disabled=1 androidboot.bootdevice=7824900.sdhci loop.max_part=7
BOARD_KERNEL_CMDLINE += firmware_class.path=/vendor/firmware_mnt/image
BOARD_KERNEL_CMDLINE += androidboot.selinux=permissive
BOARD_KERNEL_IMAGE_NAME := Image.gz-dtb
BOARD_KERNEL_OFFSET = 0x00008000
BOARD_KERNEL_PAGESIZE := 2048
BOARD_KERNEL_TAGS_OFFSET := 0x00000100
BOARD_RAMDISK_OFFSET := 0x01000000
TARGET_KERNEL_ARCH := arm64
TARGET_KERNEL_SOURCE := kernel/lenovo/msm8953
