参数：

类型参数名称
struct inode *inode
const char *name
const void *value
size_tsize
intflags
2687  nsp等于smack_inode(inode)
2690  rc等于0
2692  如果value恒等于NULL或size大于SMK_LONGLABEL或size恒等于0则返回:负EINVAL
2695  skp等于smk_import_entry(value, size)
2696  如果是错误则返回:错误
2699  如果字符串比较恒等于0则
2700  label of the fso 等于skp
2701  smack inode flags 或等于de is instantiated
2702  返回:0
2707  如果s_magic不等于SOCKFS_MAGIC则返回:负EOPNOTSUPP
2710  sock等于SOCKET_I(inode)
2711  如果(sock == NULL || sk == NULL)则返回:负EOPNOTSUPP
2714  ssp等于sk_security
2716  如果字符串比较恒等于0则 inbound label 等于skp
2718  否则如果字符串比较恒等于0则
2719  outbound label 等于skp
2720  如果sk_family恒等于PF_INET则
2721  rc等于smack_netlabel - Set the secattr on a socket*@sk: the socket*@labeled: socket label scheme* Convert the outbound smack value (smk_out) to a* secattr and attach it to the socket.* Returns 0 on success or an error code
2722  如果rc不等于0则printk - print a kernel message*@fmt: format string* This is printk(). It can be called from any context. We want it to work.* We try to grab the console_lock. If we succeed, it's easy - we log the* output and call the console drivers
2727  否则返回:负EOPNOTSUPP
2731  如果sk_family恒等于PF_INET6则smk_ipv6_port_label - Smack port access table management*@sock: socket*@address: address* Create or update the port list entry
2735  返回:0

名称描述
smack_inode_notifysecctxThere used to be a smack_release_secctx hook* that did nothing back when hooks were in a vector.* Now that there's a list such a hook adds cost.
