I want to trace the mutex variables in my rust program(e.g. which mutex called lock() and unlock() methods). And I think there're static methods.

  • Why not instrument every call instruction and see if the call target is your function of choice?

In instruction instrumentation function, you can check if the instruction is indeed a call instruction. Something like -

if (INS_IsCall(ins))
        if (INS_IsDirectCall(ins))

Then get the name of the routine:

if (RTN_FindNameByAddress(INS_DirectBranchOrCallTargetAddress(ins)) 
== "yourfavouritefun")
do something;

And you can obviously log the caller.

VOID Instruction(INS ins, VOID *v) {
ADDRINT insaddress = INS_Address(ins);
if (RTN_FindNameByAddress(insaddress))
  do something more;
  • So how to find the callers of instruction (i.e., how to distinguish different callers of the same instruction)?
