OpenBSD 6.7 crashes on APU2C4 with LTE modem Huawei E3372s-153 HiLink

emigrant-2
Hi everyone,

After a few hours OpenBSD 6.7 crashes to ddb> . Without a LTE modem OpenBSD 6.7 works stable. Huawei E3372s-153 HiLink on OpenBSD 6.6 works perfectly, stable. Something wrong with USB, xHCI or cdce on OpenBSD 6.7 imho.

Re: OpenBSD 6.7 crashes on APU2C4 with LTE modem Huawei E3372s-153 HiLink

emigrant-2
Probably power supply 12 V is broken. Showing 16,87 V(Fluke 179) - too high. Should be 12,25-12,50 V. I replaced to the new one.

That might be why the device stops responding.  The fact that cleaning
up from a failed USB transaction leads to this panic is a bug though.

And somebody just posted a very similar panic with ure(4).  Something
in the network stack is holding a mutex when it shouldn't.

I think that holding the mutex is ok. The bug is calling the stop
routine in case of errors.

This is what common foo_start() does:

        m_head = ifq_deq_begin(&ifp->if_snd);
        if (foo_encap(sc, m_head, 0)) {
                ifq_deq_rollback(&ifp->if_snd, m_head);
                ...
                return;
        }
        ifq_deq_commit(&ifp->if_snd, m_head);

Here, ifq_deq_begin() grabs a mutex and it is held while
calling foo_encap().

For USB network interfaces foo_encap() mostly does this:

        err = usbd_transfer(sc->sc_xfer);
        if (err != USBD_IN_PROGRESS) {
                foo_stop(sc);
                return EIO;
        }

And foo_stop() calls usbd_abort_pipe() -> xhci_command_submit(),
which might sleep.

How to fix? We could do the foo_encap() after the ifq_deq_commit(),
possibly dropping the current mbuf if encap fails (who cares
for the packets after foo_stop() anyway).

Or change all the drivers to follow the path that if_aue.c takes:

        err = usbd_transfer(c->aue_xfer);
        if (err != USBD_IN_PROGRESS) {
                ...
                /* Stop the interface from process context. */
                usb_add_task(sc->aue_udev, &sc->aue_stop_task);
                return (EIO);
        }

Any ideas, what's better? Or alternative proposals?

That's the approach taken by drivers using ifq_dequeue(9) instead of
ifq_deq_begin/commit().

That's just trading the current problem for another one with higher
complexity.

Using ifq_dequeue(9) would have the advantage of unifying the code base.
It introduces a behavior change.  A simpler fix would be to call
foo_stop() in the error path after ifq_deq_rollback().

Right now LTE modem working on internal USB 2.0(EHCI). External is USB 3.0(xHCI). We will see… :)

LTE modem works correctly under usb 2.0(EHCI), no panics. Uptime almost 2 days. Something is broken in xHCI (xhci.c?).
Any patch for 6.7 soon, or is it more complicated?
