binflow v0.0.1 This software is a re-design of ftrace (https://github.com/elfmaster/ftrace) which was somewhat popular but has some naive implementation qualities that make it slow, and not suitable for some applications. binflow is much faster, and has better argument resolution and will be able to handle multi-threaded applications/processes. Currently it is only 30% complete and does not yet handle return values. Stay tuned. Here is an example of binflow tracing a binary that was compiled from the following source code: int f(int a, int b, int c) { printf("%d, %d, %d\n", a, b, c); } int main(void) { int j = 0; int i; char *ptr = strdup("Hello"); char buf[255]; strncpy(buf, "hello", 8); printf("%s\n", buf); printf("%s\n", ptr); f(3, 2, 1); for (i = 0; i < 3; i++) f(1 + i, 2, 3 + i); } $ ./binflow -s -b ./test PLT_call@0x4005b4: __libc_start_main() LOCAL_call@0x4007ae: _init() LOCAL_call@0x4006d3: strdup("Hello") PLT_call@0x4006f3: strncpy((stack_t *)7fffef7a1c90, "hello", 0x8) PLT_call@0x400702: puts("hello") hello PLT_call@0x400711: puts("Hello") Hello LOCAL_call@0x400725: f(0x3, 0x2, 0x1) PLT_call@0x4006a3: printf("%d, %d, %d\n", 0x3, 0x2, 0x2) 3, 2, 1 LOCAL_call@0x40074f: f(0x1, 0x2, 0x3) PLT_call@0x4006a3: printf("%d, %d, %d\n", 0x1, 0x2, 0x2) 1, 2, 3 LOCAL_call@0x40074f: f(0x2, 0x2, 0x4) PLT_call@0x4006a3: printf("%d, %d, %d\n", 0x2, 0x2, 0x2) 2, 2, 4 LOCAL_call@0x40074f: f(0x3, 0x2, 0x5) PLT_call@0x4006a3: printf("%d, %d, %d\n", 0x3, 0x2, 0x2) 3, 2, 5 $
