函数名称：sel_netnode_sid - Lookup the SID of a network address*@addr: the IP address*@family: the address family*@sid: node SID* Description:* This function determines the SID of a network address using the fastest* method possible

函数原型：int sel_netnode_sid(void *addr, u16 family, unsigned int *sid)

返回类型：int

参数：

类型参数名称
void *addr
u16family
unsigned int *sid
254  _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
255  node等于sel_netnode_find - Search for a node record*@addr: IP address*@family: address family* Description:* Search the network node table and return the record matching @addr. If an* entry can not be found in the table return NULL.
256  如果(node != NULL)则
257  sid等于 SID for this node
258  _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()
259  返回:0
261  _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()
263  返回:sel_netnode_sid_slow - Lookup the SID of a network address using the policy*@addr: the IP address*@family: the address family*@sid: node SID* Description:* This function determines the SID of a network address by quering the* security policy
