[c++ Unix] Diverses questions

Salut et merci.

Je viens d'essayer 2 faire / adapter 2 codes ...

Code:

1
2
3
4
5
6
7
8
9
10
11
12
13
14

  cap_t caps;
  cap_value_t cap_list[1];
  caps = cap_get_proc();
  if (caps == NULL)
    {
      std::cout << "error1" << std::endl;
      return ;
    }
  cap_list[0] = CAP_SYS_BOOT;
  if (cap_set_flag(caps, CAP_EFFECTIVE, 1, cap_list, CAP_SET) == -1)
    {
      std::cout << "error2" << std::endl;
      return ;
    }
  if (cap_set_proc(caps) == -1)
    {
      std::cout << "error3" << std::endl;
      return ;
    }
  if (cap_free(caps) == -1)
    {
      std::cout << "error4" << std::endl;
      return ;
    }

=> l'exécution du prog m'affiche "Error3"

Code:

1

cap_t cur;
    int uid = getuid();
    if (prctl(PR_SET_KEEPCAPS, 1))
    {
    std::cout << "Error1" << std::endl;
    return ;
    }
    if (setresuid(uid, uid, uid))
    {
    std::cout << "Error2" << std::endl;
    return ;
    }
    cur = cap_from_text("cap_sys_boot=eip");
    if (cur == NULL)
    {
    std::cout << "Error3" << std::endl;
    return ;
    }
    if (cap_set_proc(cur) == -1)
    {
    std::cout << "Error4" << std::endl;
    cap_free(cur);
    return ;
    }
    cap_free(cur);

=> Celui-ci "Error4"

Dans tout les cas le cap_set_proc ne passe pas !
