函数名称：apparmor_socket_post_create - setup the per-socket security struct* Note:* - kernel sockets currently labeled unconfined but we may want to* move to a special kernel label* - socket may not have sk here if created with sock_create_lite or* sock_alloc

函数原型：static int apparmor_socket_post_create(struct socket *sock, int family, int type, int protocol, int kern)

返回类型：int

参数：

847  如果kern则
848  ns等于aa_get_current_ns()
850  label等于aa_get_label(ns_unconfined(ns))
851  aa_put_ns - decrement refcount on @ns*@ns: namespace to put reference of* Decrement reference count of @ns and if no longer in use free it
852  否则label等于aa_get_current_label - get the newest version of the current tasks label* Returns: newest version of confining label (NOT NULL)* This fn will not update the tasks cred, so it is safe inside of locks* The returned reference must be put with aa_put_label()
855  如果sk则
856  ctx等于SK_CTX(sk)
858  aa_put_label(label)
859  label等于aa_get_label(label)
861  aa_put_label(label)
863  返回:0
