函数名称：sel_netif_sid - Lookup the SID of a network interface*@ns: the network namespace*@ifindex: the network interface*@sid: interface SID* Description:* This function determines the SID of a network interface using the fastest* method possible

函数原型：int sel_netif_sid(struct net *ns, int ifindex, unsigned int *sid)

返回类型：int

参数：

类型参数名称
struct net *ns
intifindex
unsigned int *sid
196  _read_lock() - mark the beginning of an RCU read-side critical section* When synchronize_rcu() is invoked on one CPU while other CPUs* are within RCU read-side critical sections, then the* synchronize_rcu() is guaranteed to block until after all the other
197  netif等于sel_netif_find - Search for an interface record*@ns: the network namespace*@ifindex: the network interface* Description:* Search the network interface table and return the record matching @ifindex.* If an entry can not be found in the table return NULL.
198  如果此条件成立可能性大(为编译器优化)(netif != NULL)则
199  sid等于 SID for this interface
200  _read_unlock() - marks the end of an RCU read-side critical section.* In most situations, rcu_read_unlock() is immune from deadlock.* However, in kernels built with CONFIG_RCU_BOOST, rcu_read_unlock()
201  返回:0
203  _read_unlock() - marks the end of an RCU read-side critical section.* In most situations, rcu_read_unlock() is immune from deadlock.* However, in kernels built with CONFIG_RCU_BOOST, rcu_read_unlock()
205  返回:sel_netif_sid_slow - Lookup the SID of a network interface using the policy*@ns: the network namespace*@ifindex: the network interface*@sid: interface SID* Description:* This function determines the SID of a network interface by quering the
