Hi,

I have compiled Linux v5.5-rc1 and thought all was good until I 
hot-removed a Gigabyte Aorus eGPU from Thunderbolt. The driver for the 
GPU was not loaded (blacklisted) so the crash is nothing to do with the 
GPU driver.

We had:
- kernel NULL pointer dereference
- refcount_t: underflow; use-after-free.

Attaching dmesg for now; will bisect and come back with results.

I am not sure why only this eGPU causes the issue - all my other devices 
do not trigger the bug.

I will shortly re-post my 4-patch series with some trivial alterations for v5.5.

Kind regards,
Nicholas

Obvious question is: does it work on in v5.4?

Always a good question to ask. The answer is "yes".

I would have noticed had it happened in v5.4 - I am constantly playing 
with Thunderbolt and the kernel. But I tried on v5.4 just now, just to 
be sure, and it works fine. I probably should have double checked, just 
in case, though.

Bisect to come.

Kind regards,
Nicholas

Looks like something related to iommu. Does it work if you disable it?
(intel_iommu=off in the command line).

I thought it could be that, too.

The attachment "dmesg-4" from the original email is with iommu parameters.
The attachment "dmesg-5" from the original email is with no iommu parameters.
Attaching here "dmesg-6" with the iommu explicitly set off like you said.

No difference, still broken. Although, with iommu off, there are less stack traces.

Could it be sysfs-related?

Kind regards,
Nicholas

Bisect would probably be the best option to find the culprit commit.
There are couple of commits done for pciehp so reverting them one by one
may help as well:

  87d0f2a5536f PCI: pciehp: Prevent deadlock on disconnect
  75fcc0ce72e5 PCI: pciehp: Do not disable interrupt twice on suspend
  b94ec12dfaee PCI: pciehp: Refactor infinite loop in pcie_poll_cmd()
  157c1062fcd8 PCI: pciehp: Avoid returning prematurely from sysfs requests

You are not going to believe this. The offending commit is in the SOUND 
subsystem. I thought I had messed up the bisect when only sound commits 
were showing near the end.

And yes, I double checked.

Reverted, compiled, tested that it started working.
Reapplied, compiled, tested that it stopped working.
Twice.

The following is the culprit responsible for the issues:

commit 586bc4aab878efcf672536f0cdec3d04b6990c94
Author: Alex Deucher <alexander.deucher@amd.com>
Date:   Fri Nov 22 16:43:50 2019 -0500

    ALSA: hda/hdmi - fix vgaswitcheroo detection for AMD

It is playing with PCI devices. Clearly they did not consider 
hot-removal. I am guessing it is seeing the audio PCI func of the AMD 
card in that Thunderbolt eGPU enclosure.

I will collect information, make a bugzilla report and contact the AMD 
team. If anybody wants to be cc'd in then let me know. Sorry for 
bothering you and Bjorn with something which actually has nothing 
directly to do with the PCI subsystem or Thunderbolt.

I strongly hope that the upcoming Intel Xe GPU driver allows for 
surprise-removal in Linux without any crashing of kernel or userspace. 
The amdgpu and nouveau drivers do not take to surprise removal kindly, 
even without the above sound bug applying to AMD.

Kind regards,
Nicholas

No problem. Thanks for taking time to bisect the issue.

Oh this looks really like a bug, even if this isn't the root cause.

Care to submit a proper patch?

Yes, removing the pci_dev_put() as above solves the issue.

Thanks.

Kind regards,

* [PATCH] ALSA: hda/hdmi - Fix duplicate unref of pci_dev

Nicholas Johnson reports a null pointer deref as well as a refcount
underflow upon hot-removal of a Thunderbolt-attached AMD eGPU.
He's bisected the issue down to commit 586bc4aab878 ("ALSA: hda/hdmi -
fix vgaswitcheroo detection for AMD").

The commit iterates over PCI devices using pci_get_class() and
unreferences each device found, even though pci_get_class()
subsequently unreferences the device as well.  Fix it.

Extremely fast turnaround from bisect to patch.

If you want the bugzilla.kernel.org report then I can do that ASAP, but 
I feel that it is redundant now.

Thank you for handling my bug report.

Nicholas

We have now Link tag to track the ML archive, so it should suffice, I
suppose.

And thank you for your quick testing.

The pci_dev_put() a few lines above should probably be dropped as well.

That one looks fine to me.  The refcount is already increased in the
caller get_bound_vga() via pci_get_domain_bus_and_slot() and it's
increased again in atpx_present() via pci_get_class().  It needs to
be decremented in atpx_present() to avoid leaking a ref.

Thanks,

I'm not following.  This is part of the same loop as the one you removed.  All we are doing is checking whether the ATPX method exists or not om the platform.  The pdev may not be the same one as the one in pci_get_domain_bus_and_slot().  The APTX method in the APU's ACPI namespace, not the dGPUs.

Well, the tricky part is that pci_get_class() itself does
unrefeference the old object and reference the new object (if found).
At the end of the loop, nothing is referenced, so it's fine.
OTOH, if you go out of the loop in the middle, you're still keeping
the pdev object reference, so you need to manually unreference it.

Okay.  Still, atpx_present() doesn't pass the found pci_dev back to the
caller, so it would be leaked if the ref isn't returned.

The situation is different for the pci_dev_put() I removed:  The ref is
returned by pci_get_class() on the next loop iteration.

Thanks,

decremented to zero. Hotplug service dereferences NULL pointer when 
remove the device from the device lists.
