Dear all, I would like to retrieve the information whether variables inside source files can be influenced from user land, e.g. to identify variables that store arguments to syscalls. Is there already a tool that offers this feature? I understand that the 'smatch_data/db/smdb.py $func' tool can be used to trace calls to a function $func. Furthermore, 'smatch_data/db/smdb.py trace_param $func' allows to trace how function parameters are traced. However, both commands do not present the information I am looking for. I also did not find such labels in the tables of the created data base file. I wondered whether I simply miss something.
