Bug#110015: FS server crashs a subhurd

[Moritz Schulte]

Hi again,

the following change in init/init.c works:

--- init.c.orig Sat Aug 25 19:12:13 2001
+++ init.c      Sat Aug 25 19:12:26 2001
@@ -1182,7 +1182,8 @@ S_startup_essential_task (mach_port_t se
          startup_essential_task_reply (reply, replytype, 0);
 
          init_stdarrays ();
-         frob_kernel_process ();
+         if (! fakeboot)
+           frob_kernel_process ();
 
          launch_system ();
 

But i don't know wether that's the right fix. The problem is that
frob_kernel_process() tries to register the kernel task (pid 2) as an
essential task:

  err = proc_pid2task (procserver, 2, &task);
  if (err)
    {
      error (0, err, "cannot get kernel task port");
      return;
    }
  err = proc_task2proc (procserver, task, &proc);
  if (err)
    {
      error (0, err, "cannot get kernel task's proc server port");
      mach_port_deallocate (mach_task_self (), task);
      return;
    }

  /* Mark the kernel task as an essential task so that we never
     want to task_terminate it.  */
  err = record_essential_task ("kernel", task);
  assert_perror (err);


This doesn't work right in a subhurd.

Btw, I find the mixture of parent-Hurd-processes and
child-Hurd-processes quite confusing. Is it difficult to modify proc
so that you can _not_ see the processes from parent Hurds? IMHO, this
would be better.
