问如何获取套接字的拥有者进程？

struct task_struct *task;
struct list_head *t, *t1;
...
list_for_each(t, t1) {
#ifdef CONFIG_UIDGID_STRICT_TYPE_CHECKS
    if ((task_uid(task)).val == 0) /* no root processes, only userspace*/
#else
    if ((task_uid(task)) == 0)
#endif
    continue;
    task = list_entry(t, struct task_struct, tasks);
    /*Now you have task_struct of userspace program*/
    /*and may do whatever you want ))) */
    /*E.g. to figure out opened file descriptors*/
}
