Permissive v4 Tweak for Xiaomi Devices

Permissive v4 Tweak for Xiaomi Devices 1

Android OS is a mobile operating system based on Unix. It uses similar kernel as Linux kernel. Therefore, you may find some of its settings are similar to Linux.

One of the features in term of security aspect is SELinux. Security-Enhanced Linux (SELinux) is a Linux kernel security module that provides a mechanism for supporting access control security policies, including mandatory access controls (MAC) – Wikipedia.

In another words, it is a security measure to add additional layer of security to a Linux-based machine/device. It is a set of kernel modifications and user-space tools essential to separate enforcement of security decisions from the security policy.

Such a technology can also be found in recent Android devices. Xiaomi phones are not exclusive to the feature, including all the variants in Mi, Redmi, and Redmi Note families.

Shortly, SELinux is there to help you preventing the potential of unauthorized malicious attacks on your device.

However, just like any other security mechanism, there is always the On-Off button to trigger the mechanism. The case of SELinux is similar.

SELinux runs in one of three modes by default:

  • Disabled , meaning not enabled in the kernel;
  • Permissive , meaning SELinux is running and logging but not controlling permissions;
  • Enforcing , meaning SELinux is running and enforcing policy.

Flashing maniacs may (or may not) find SELinux not as useful as expected. Some custom ROMs need to have it either disabled or set to Permissive so that flashing can happen.

Luckily, as long as the bootloader is unlocked, setting SELinux to Permissive mode is possible thanks to a small script flash-able through TWRP.

  1. Why don’t you just use setenforce command with su in a terminal?

    ~$ setenforce –help
    usage: setenforce [enforcing|permissive|1|0]

    Sets whether SELinux is enforcing (1) or permissive (0).
