Ejemplo n.º 2

Archivo: aegis.cpp Proyecto: cxl000/timed

credentials_t Aegis::credentials_from_dbus_connection(const QDBusMessage &message)
{
  // We are doing this in a kinda insecure way. Two steps:
  // 1. Ask dbus daemon, what is the pid of the client.
  // --- race race race --- (please someone file a bug about it) --- race race race ---
  // 2. Ask aegis kernel extension, what are the credentials of given pid.

  QString sender = message.service() ;
  /* "returns "sender" on inbound messages
      and "service" on outbound messages
      which saves one QString object and
      confuses at least me ..." -- so true ! */

  // 1. Ask DBus daemon, what is the PID of the 'sender':

  uint32_t owner_id = get_name_owner_from_dbus_sync(Maemo::Timed::bus(), sender) ;

  if (owner_id == ~0u)
  {
    log_warning("can't get owner (pid) of the caller, already terminated?") ;
    return credentials_t() ;
  }

  pid_t pid = owner_id ;

  // 2. Getting aegis credentials from the kernel, by pid

  creds_t aegis_creds = creds_gettask(pid) ;

  // Don't check result, as NULL is a valid set of aegis credentials

  credentials_t creds = Aegis::credentials_from_creds_t(aegis_creds) ;

  creds_free(aegis_creds) ;

  return creds ;
