PATCH 1/1 acpi: pci_root: fix NULL pointer deref after resume from suspend

commit 275582 introduces acpi_get_pci_dev(), but pdev->subordinate can be NULL, then a NULL was passed to pci_get_slot, this results the kernel oops when resume from suspend.

This patch resolves following kernel oops:

I'm a little confused by this. If we start from the PCI root bridge and walk back down the hierarchy, shouldn't everything between the root and the device be a P2P bridge?

What is special about suspend/resume that causes the subordinate bus to become NULL?

Can you send the full stacktrace?

Thanks.

Well, if my reading of the code is correct, there's no guarantee that pci_get_slot() will always return either the right device or a bridge. If it returns anything that's not a bridge or the device we're looking for, we'll hit the NULL pointer deref.

In fact it looks like we should also clear pdev if no device was found.

Thanks,

I should have been more precise.

If devfn of node happens to be the same as devfn of a non-bridge device on pbus, the pci_get_slot() will return a valid pointer to it, but pdev->subordinate will be NULL. Is it impossible for some reason?

Hm, that's a good thought, but I'm still confused. Here's the first part of the full function (acpi_get_pci_dev):

        phandle = handle;
        while (!acpi_is_root_bridge(phandle)) {
                node = kzalloc(sizeof(struct acpi_handle_node), GFP_KERNEL);
                if (!node)
                        goto out;

                INIT_LIST_HEAD(&node->node);
                node->handle = phandle;
                list_add(&node->node, &device_list);

                status = acpi_get_parent(phandle, &phandle);
                if (ACPI_FAILURE(status))
                        goto out;
        }

phandle starts off as the input parameter, and we make successive calls to acpi_get_parent() to walk up the ACPI device tree until we get to a root bridge.

My assumption here is that all those ACPI devices must be P2P bridges.

        root = acpi_pci_find_root(phandle);
        if (!root)
                goto out;

        pbus = root->bus;

Now we've got an acpi_pci_root() which has a struct pci_bus, and we can start walking back down the PCI tree. Except what we're really doing is iterating across the device_list which we created above.

device_list should only contain P2P bridges, based on my assumption above.

        list_for_each_entry(node, &device_list, node) {
                acpi_handle hnd = node->handle;
                status = acpi_evaluate_integer(hnd, "_ADR", NULL, &adr);
                if (ACPI_FAILURE(status))
                        goto out;
                dev = (adr >> 16) & 0xffff;
                fn  = adr & 0xffff;

                pdev = pci_get_slot(pbus, PCI_DEVFN(dev, fn));
                if (!pdev || hnd == handle)
                        break;

                pbus = pdev->subordinate;
                pci_dev_put(pdev);
        }

The point you raise about collision between the devfn of 'node' and some non-bridge device returned by pci_get_slot() seems like it really shouldn't happen, because we evaluate _ADR for each node on device_list, in the reverse order that we found them, and based on my assumption, all those nodes should be bridges.

I'm not saying that Xiaotian's patch is wrong. I'm saying I'd like to be educated as to why my basic assumption was wrong, because now you're making me think that this code is pretty fragile. :-/

Thanks.

Is there any cases that pdev->subordinate is NULL while pdev is bridge device? From pci_slot.c::walk_p2p_bridge, there's code like following:

        dev = pci_get_slot(pci_bus, PCI_DEVFN(device, function));
        if (!dev || !dev->subordinate)
                goto out;

It looks like dev->subordinate can be NULL even if in p2p bridge, right?

Thanks
Xiaotian

The point you raise about collision between the devfn of 'node' and some non-bridge device returned by pci_get_slot() seems like it really shouldn't happen, because we evaluate _ADR for each node on device_list, in the reverse order that we found them, and based on my assumption, all those nodes should be bridges.
You seem to be right, but if the Xiaotian's patch actually fixes the NULL pointer deref, one of the assumptions is clearly wrong.
Quoted 4 lines
I'm not saying that Xiaotian's patch is wrong. I'm saying I'd like to be educated as to why my basic assumption was wrong, because now you're making me think that this code is pretty fragile. :-/
Quoted 6 lines
Perhaps Xiaotian can add some printk()s on top of his patch that will show us exactly in what conditions pbus becomes NULL.
Thanks,
Rafael
Is there any cases that pdev->subordinate is NULL while pdev is bridge device?
From pci_slot.c::walk_p2p_bridge, there's code like following:

Quoted 5 lines

         dev = pci_get_slot(pci_bus, PCI_DEVFN(device, function));
         if (!dev || !dev->subordinate)
                 goto out;
It looks like dev->subordinate can be NULL even if in p2p bridge, right?

Right, in general, but in this particular case each device we inspect is supposed to be a parent of another device, which implies that there's a bus below it (given that it's a PCI device).

Thanks,
Rafael

In the code you post above, that results from doing an ACPI namespace walk, which will definitely find non-bridge devices.

Right, that's why I'm surprised that my assumption broke. But now that I see that a dock device is involved, maybe that's not so surprising.

Yeah. Still, I'd like to know the root cause.

commit 275582 introduces acpi_get_pci_dev(), but pdev->subordinate can be NULL, then a NULL was passed to pci_get_slot, this results the kernel oops when resume from suspend.

I'm a little confused by this. If we start from the PCI root bridge and walk back down the hierarchy, shouldn't everything between the root and the device be a P2P bridge?

What is special about suspend/resume that causes the subordinate bus to become NULL?

Have you checked (using gdb) which source code line this corresponds to?

Yep, the code line corresponds to
pdev = pci_get_slot(pbus, PCI_DEVFN(dev, fn));

Also gdb shows pci_bus->devices has offset of 0x28.

I've put some check in acpi_get_pci_dev, it shows that pbus is NULL when the panic happens.

Hi Xiaotian,
Thanks for the bug report.

commit 275582 introduces acpi_get_pci_dev(), but pdev->subordinate can be NULL, then a NULL was passed to pci_get_slot, this results the kernel oops when resume from suspend.
This patch resolves following kernel oops:

I'm a little confused by this. If we start from the PCI root bridge and walk back down the hierarchy, shouldn't everything between the root and the device be a P2P bridge?

Well, that's what I'd like to find out.

Can you please build the kernel with CONFIG_PM_VERBOSE set and with the $subject patch applied and post a dmesg output from it containing at least one suspend-resume cycle?

Can you please reproduce with this debug patch? I'm guessing that we're dying because we have a NULL parent device, but I'm curious as to what causes this situation to occur.

If we had a NULL parent, acpi_get_parent() would return an error. Also, if we one of the devices is NULL at the PCI level, pci_get_slot() will return NULL. The only possibility left is that one of the buses we find in the ACPI tables doesn't have a secondary PCI bus.

I think what happens is that on resume we get a dock notification (via dock_acpi_notifier registered in dock_init()) for a dock station device that is present in the ACPI tables, but not physically accessible at the moment (I guess that falls into the "BIOS bug" category, but we can fix this easily in the kernel).

So, IMO, the appended patch is the right fix.

Danny, please test it and report back (in particular, please tell us if you see the "Secondary bus not present" message in dmesg).

Thanks,
Rafael

Can you please reproduce with this debug patch? I'm guessing that we're dying because we have a NULL parent device, but I'm curious as to what causes this situation to occur.
If we had a NULL parent, acpi_get_parent() would return an error. Also, if we one of the devices is NULL at the PCI level, pci_get_slot() will return NULL. The only possibility left is that one of the buses we find in the ACPI tables doesn't have a secondary PCI bus.
I think what happens is that on resume we get a dock notification (via dock_acpi_notifier registered in dock_init()) for a dock station device that is present in the ACPI tables, but not physically accessible at the moment (I guess that falls into the "BIOS bug" category, but we can fix this easily in the kernel).
So, IMO, the appended patch is the right fix.
Danny, please test it and report back (in particular, please tell us if you see the "Secondary bus not present" message in dmesg).
Thanks,
Rafael

Sorry for the late response, just back from holidays. Will test it soon, thanks.
