    can you expand on why this might be a problem, as far I can tell the
    syscall is in fs/open.c

    it seems very simple to me

    asmlinkage long sys_vhangup(void)
    if (capable(CAP_SYS_TTY_CONFIG)) {
    return 0;
    return -EPERM;

    basically, we call tty_vhangup on the process's tty.

    if tty_vhangup was the syscall, I could see this being a problem, but as
    sys_vhangup can only operate on the what the task_struct has, how is it
    a problem?
