函数名称：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

函数原型：static int selinux_netlbl_sidlookup_cached(struct sk_buff *skb, u16 family, struct netlbl_lsm_secattr *secattr, unsigned int *sid)

返回类型：int

参数：

类型参数名称
struct sk_buff *skb
u16family
struct netlbl_lsm_secattr *secattr
unsigned int *sid
48  rc等于security_netlbl_secattr_to_sid( & selinux_state, secattr, sid)
49  如果rc恒等于0且flags按位与NETLBL_SECATTR_CACHEABLE且flags按位与NETLBL_SECATTR_CACHE则netlbl_cache_add(skb, family, secattr)
54  返回:rc
