unsigned int *sid
196  如果非LSM protocol operations (NetLabel LSM/kernel API)则
197  sid等于unspecified SID

201  lbl_secattr_init - Initialize a netlbl_lsm_secattr struct*@secattr: the struct to initialize* Description:* Initialize an already allocated netlbl_lsm_secattr struct.
202  rc等于netlbl_skbuff_getattr(skb, family, & secattr)
203  如果rc恒等于0且flags不等于map values for 'flags' 则rc等于selinux_netlbl_sidlookup_cached - Cache a SID lookup*@skb: the packet*@secattr: the NetLabel security attributes*@sid: the SID* Description:* Query the SELinux security server to lookup the correct SID for the given* security attributes
206  否则sid等于unspecified SID
208  type等于type
209  lbl_secattr_destroy - Clears a netlbl_lsm_secattr struct*@secattr: the struct to clear* Description:* Destroys the @secattr struct, including freeing all of the internal buffers.* The struct must be reset with a call to netlbl_secattr_init() before reuse.
