Now, I’m trying to build the dependency graph of System Call according
to information flow.
For example, SystemCallA( para 1, para 2) , SystemCallB(para3, para4).
If para1 and its propagation were used by SystemCallB, we see
SystemCallB depends on SystemCallA because the data flows from
SystemCallA to SystemCallB. I know TEMU can track information flow.
But I’m not sure if it can track the information flow of System calls.
So, Could you tell me if TEMU can do this or some tips to implement
it ? Thank you very much.
