TDA4VM: how to enable selinux?

Ni Hua

Part Number: TDA4VM

Dear TI,

I have a problem with DeviceTree Source.

I add selinux in kernel.
Bootargs are set in the dts/ti/k3-j7200-common-proc-board.dts file, "security=selinux" is added.

After startup, there is no "security=selinux" in the Kernel command line. selinux is not enabled.

Hello,

We do not support selinux option by default. Is adding only the bootargs sufficient? don't we need to enable additional configs to enable in kernel?

Best Regards,

Keerthy

We have configured selinux in the kernel.

How to add bootargs to take effect in Kernel command line?

Thank you.

Hi,

Can you add in the following file:

File: $PSDK_Linux/board-support/u-boot-2023.04*/include/environment/ti/mmc.env

Original Variable: args_mmc=run finduuid;setenv bootargs console=${console}
        ${optargs}
        root=PARTUUID=${uuid} rw
        rootfstype=${mmcrootfstype}
Once you add: args_mmc=run finduuid;setenv bootargs console=${console}
        ${optargs}
        root=PARTUUID=${uuid} rw
        rootfstype=${mmcrootfstype}security=selinux

Try and let me know if this helps.

Best Regards,
Keerthy
