Poul-Henning Kamp c01a009dc5 With the new kernel dev_t conversions done at release 4.X, ... it becomes possible to trap in ptsstop() in kern/tty_pty.c if the slave side has never been opened during the life of a kernel. What happens is that calls to ttyflush() done from ptyioctl() for the controlling side end up calling ptsstop() [via (*tp->t_stop)(tp, <X>)] which evaluates the following: struct pt_ioctl *pti = tp->t_dev->si_drv1; In order for tp->t_dev to be set, the slave device must first be opened in ttyopen() [kern/tty.c]. It appears that the only problem is calls to (*tp->t_stop)(tp, <n>), so this could also happen with other ioctls initiated by the controlling side before the slave has been opened.
