Hi Anton,
Thanks your help and support.
I’ve followed your suggestion to enable selinux kernel configuration and have seen kernel message “[ 0.002268] SELinux: Initializing.” during boot time, but still returns “Disabled”
after executing getenforce command.
The selinux mode and type I set in /etc/selinux/config file is permissive and minimum. Could you help to advise me whether there’s some settings need to set to avoid this problem.
Thanks,
Ivan

Hello, Ivan.
Perhaps, you should enable selinux kernel configuration as well. The openbmc kernels, if I'm not mistaken, have different recipes.
The default configuration relies on linux-yocto package:
You should include this selinux.cfg in on of the openbmc kernel layers:
SRC_URI += "file://selinux.cfg"
and copy selinux.cfg to one of the local files location.

Hi Andrew and Artem,
Per your suggestion, I try to enable SELinux with Yocto SELinux layer(http://git.yoctoproject.org/cgit/cgit.cgi/meta-selinux) and 64MiB flash part.
But encountered one problem which is when I use command "getenforce" to check SELinux mode, it always returns "Disabled" even if SELinux mode in config file '/etc/selinux/config' is permissive or enforcing by default.
Please help to advise it.
