689  smk_netlabel_audit_set - fill a netlbl_audit struct*@nap: structure to fill
691  rc等于LSM configuration operations
692  如果rc不等于0则printk - print a kernel message*@fmt: format string* This is printk(). It can be called from any context. We want it to work.* We try to grab the console_lock. If we succeed, it's easy - we log the* output and call the console drivers
696  doip等于开辟内存
697  如果(doip == NULL)则panic - halt the system*@fmt: The text string to print* Display a message, then perform cleanups.* This function never returns.
699  std = NULL
700  doi等于smk_cipso_doi_value
701  type等于CIPSO_V4_MAP_PASS
702  tags[0]等于CIPSO_V4_TAG_RBITMAP
