SELinux Internals

I am studying how selinux is implemented in the kernel. This obiously enables me to know how lsm is also spread out in the kernel. I have not yet started out with LXR and ima because IMA is a patch and not source code! Well patch can be viewed as a text document but I did not find any source code. Does this mean I am stupid? Actually the patch has all the code layed in the open so I don’t know what to do.

I have also downloaded TrouSeRs which is source code. I can give it a try as well. I can try tpm emulator as well! For the time being I am concentrating on SELinux internal architecture implementation as lsm.

Mr. MMA have you gone through Leveraging of IPSEC for distributing of SElinux? I have a strong feeling that its going to be of good use. It is also part of the linux kernel since kernel 2.6.16.

  1. Hi Shaz,

    Patch the kernel with IMA and then use the find command with grep to see the difference. Plus while patching, IMA also gives a list of files that are modified or added. Keep it with you, This is the source code.

    LXR will help you in source code, even e.g. if you dont have the internet connection, once you setup it.

  2. Shahbaz, present me your whole idea, on some time. Let me know, when you will be available. I want to discuss with you about your idea.

    Best,
