How to set SELinux to 0 or permissive mode in android 4.4.4 and above?

Question

I want to set the SELinux (Security Enhanced Linux) mode to Permissive or (0) on android 4.4.4 (and above if possible). I use the following command: setenforce 0

Answer 1

MUST BE ROOTED! Not sure if this works on KitKat (it should) but I use this on my Nexus 6. Run following in terminal or ADB Shell:

su
mount -o remount,rw /system
mkdir /system/su.d
echo "#!/system/bin/sh" > /system/su.d/permissive.sh
echo "echo 0 > /sys/fs/selinux/enforce" >> /system/su.d/permissive.sh
chmod 755 /system/su.d/permissive.sh

And check it after reboot by this:

su
/system/bin/getenforce
