multip register_uprobe

[Wenji Huang <wenji dot huang at oracle dot com>]

Hi,

  I am creating some test scripts based on sarikar's framework.
 
  There is one problem about register multiple times.
      .................
       probes->vaddr = vaddr;
       probes->pid = pid;
       probes->handler = handler;
       for (i=0; i < 3; i++) {
            ret = register_uprobe(probes);
            if (ret!=0)  //of course, the first time should succeed and 
will failed in second time, ret = -16
              {
I tried several possibilities:
                * return ret; //RESULT: the module can't be removed, 
the probed process will hang, can't be killed/continued
                * return 0; //RESULT: same as above
                * unregister_uprobe(probes);kfree(probes);break; 
//RESULT: same as above
                * kfree(probes);break; //RESULT: the module can be 
removed, the probed process will hang, can't be killed/continued
              }
        }
       return 0;
       .................

 But, no problem in "register once and unregister multiple times".  

 Environment:
   kernel: 2.6.21
   utrace: http://people.redhat.com/roland/utrace/2.6.21/
   uprobe: mail by Jim, on 2007/05/26
   All the tests in srikar's testsuite passed in the box.

   Any analysis? or need to update utrace/uprobe? Is there any website 
or cvs to get the resource?

Regards,
