Build kernel get error at security/selinux -- "please update secclass_map"

Hi,

I get errors like “please update secclass_map” when I am building kernel for dragonboard410c, this failure is reproducible 100%. I am surprized why there is no one report such an issue.

Code base is:
http://git.linaro.org/landing-teams/working/qualcomm/kernel.git
branch from:
origin/release/android/qcomlt-4.14

I followed instructions from -


and

I also have done a lot of searches through internet, but I really can’t find a clue… Any help is highly appreciated!

    qcom_defconfig: Disable CONFIG_ION_SYSTEM_HEAP

    Disable it because audioserver/codec2 won't start and it will
    bring down the whole system.

Here are my build steps:

export ARCH=arm64
export PATH=/work/tools/gcc-linaro-7.2.1-2017.11-x86_64_aarch64-linux-gnu/bin/:$PATH 
export CROSS_COMPILE=aarch64-linux-gnu-
make distclean
KERNEL_CONFIGS=KERNEL_CONFIGS_arm64 
make qcom_defconfig android-recommended.config android-recommended-arm64.config android-base.config
make -j16

I also tried with bellow steps, a little different in configurations:

make distclean
make qcom_defconfig android-base.config android-recommended.config
make -j16

Both will report error like “please update secclass_map”
