函数原型：static int selinux_socket_getpeersec_dgram(struct socket *sock, struct sk_buff *skb, unsigned int *secid)

返回类型：int

参数：

类型参数名称
struct socket *sock
struct sk_buff *skb
unsigned int *secid
5109  peer_secid等于unspecified SID
5113  如果skb且protocol恒等于htons(Internet Protocol packet )则family等于PF_INET
5115  否则如果skb且protocol恒等于htons(IPv6 over bluebook )则family等于PF_INET6
5117  否则如果sock则family等于sk_family
5119  否则转到:out
5122  如果sock且family恒等于PF_UNIX则
5123  isec等于inode_security_novalidate(SOCK_INODE(sock))
5124  peer_secid等于 SID of this object
5125  否则如果skb则selinux_skb_peerlbl_sid - Determine the peer label of a packet*@skb: the packet*@family: protocol family*@sid: the packet's peer label SID* Description:* Check the various different forms of network peer labeling and determine* the peer label/SID for the
