Get process list from kernel space in Linux

问题

How can I get list of all pairs process_name -> process_pid (user space and kernel space) from kernel module?

回答1:

In your kernel module, you can do something like this:

    rcu_read_lock();
    for_each_process(g) {
            printk("%s --> %d\n", g->comm, task_tgid_vnr(g));
    }
    rcu_read_unlock();
