Hi SEAndroid,

I am trying to capture all operations (mainly system calls) of a specific
domain type, such as platform_app. I do want to keep all duplicated denials
of a specific domain type along with every related system calls in the
audit log for my analysis.

I am reading the code in selinux/avc.c. I think the functions "avc_audit,
slow_avc_audit" should be related to this. Suppose the domain type I want
is "platform_app", is it possible to first check the ssid/tsid of
platform_app and then bypass the audited checking, which can force it to
call slow_avc_audit?

Furthermore, if later on I want to focus on another domain, such as
media_app, it is possible to pass the domain type as an argument from user
space to the selinux avc module to do the above job? I notice the "auditd"
daemon has some ways to send some info to the kernel. Can I use that?

Thanks in advance.

Best Regards!
