[android-developers] Re: Android 4.2 introduced SELinux enabled by default on kernel. am I right?

First of all, DroidMaster, this looks like you copied it verbatim from another website forum. Such crossposting is not always welcomed.

Secondly, ignore the lmgtfy.com links, since he did not even give you the right set of keywords for useful Google queries.

Thirdly, there seems to be some confusion on the part of the original poster (presumably you, but who knows?): SELinux is NOT a version of Linux, nor a competitor to Linux. It is a security component included with some distributions of Linux. I have had it in Fedora for quite some time now, I usually turn it off, since the default policies delivered with Fedora updates are such crap.

You can also set a mode where SELinux only advises when a process does an access forbidden by policy instead of actually blocking it. http://www.revsys.com/writings/quicktips/turn-off-selinux.html gives examples of how to do this in Fedora, but it is not exactly clear how to translate that info to the Android Linux environment.

Then again, the third of Lew's lmgtfy.com links is the only one with a good set of keywords. If you do more reading at the sites that turns up, I think you will find the answer for the Android Linux environment.

Dear Expert, 

1. As I have understood correctly, Android 4.2 introduced SELinux enabled by default on kernel. am I right. 
2. There are some of the apps might not work correctly. Do you know what kind of app is not working?
3. Is there anyway to disable it ? I check on VZW Galaxy Nexus - build JDQ39 - I am not sure what is the Linux version - Either SELinux or Linux.
4. What is the benefit of using SELinux vs Linux?

Regards,
