[PATCH v9 1/3] usb: add missing headers transitively included by <linux/phy/phy.h>

[Vladimir Oltean]

The chipidea ci_hdrc_imx driver uses regulator consumer API like
regulator_enable() but does not include <linux/regulator/consumer.h>.

The core USB HCD driver calls invalidate_kernel_vmap_range() and
flush_kernel_vmap_range(), but does not include <linux/highmem.h>.

The DWC3 gadget driver calls:
- device_property_present()
- device_property_count_u8()
- device_property_read_u8_array()
but does not include <linux/property.h>

Similarly, dwc3-imx uses device_property_read_bool() without including
<linux/property.h>.

The dwc3-generic-plat driver uses of_device_get_match_data() but does
not include <linux/of.h>.

In all these cases, the necessary includes were still provided somehow,
directly or indirectly, through <linux/phy/phy.h>. I found the following
command to be quite helpful in figuring out the include chain:

$ make KCFLAGS="-H" drivers/usb/dwc3/dwc3-imx.o

Since <linux/phy/phy.h> wants to drop the unnecessary includes, fill in
the required headers to avoid any breakage.

[PATCH v9 2/3] usb: host: tegra: avoid direct dereference of phy->dev.of_node

[Vladimir Oltean]

A piece of context which seems relevant here is that the USB subsystem
is transitioning from struct usb_phy to struct phy (belonging to the
Generic PHY subsystem). Commit 1a229d8690a0 ("Revert "usb: phy: add usb
phy notify port status API"") seems to confirm that this is the case.

In the transition process, some PHY provider drivers register themselves
as both Generic PHY and USB PHY in an attempt to bridge the API gap.
Such is the case with drivers/phy/tegra/xusb.c, accessed here by the
Tegra USB host driver. This USB host expects the PHY device behind the
Generic PHY to also be a USB PHY, and calls
devm_usb_get_phy_by_node(phy->dev.of_node).

The Generic PHY exposes no API to get the OF node from a PHY device, so
the Tegra USB host driver gets it directly. However, "struct phy" will
be made an opaque pointer, to avoid misuse, so this will no longer be
possible.

Considering the fact that the Generic PHY/USB PHY duality is a
transitional state, I am deliberately not planning to make the life of
this driver any easier by providing a helper to get to the OF node
somehow. Instead, implement a parallel lookup path through which the
Tegra USB host driver can continue to get to the OF node provided by the
padctl component, using the 'phys' phandle.

Secondly (minor issue) the driver uses the phy->dev.of_node again to
print using dev_dbg() that a "remote wake" was detected. Just print the
index at which the PHY appears inside the driver's tegra->phys[] array
instead.

[PATCH v9 3/3] usb: gadget: tegra-xudc: avoid direct dereference of phy->dev.of_node

[Vladimir Oltean]

In a somewhat similar situation as the Tegra USB host controller driver,
the Tegra XUDC driver for USB gadget mode needs to get to a struct
usb_phy that sits behind the same OF node as the Generic PHY. It does
that directly, which will no longer be possible. The PHY provider is
also the xusb padctl driver.

The rework here is also to implement a parallel OF node lookup path
based on the "phys" phandle and the #phy-cells of the padctl provider.

Some further notes:
- create a local "usbphy" variable to hold the devm_usb_get_phy_by_node()
  output. This makes the error checks more obvious (avoids keeping an
  error-encoded pointer in xudc->usbphy[i] even temporarily).
- the "if (IS_ERR(utmi_phy)) .. else if (utmi_phy) .. else if (!utmi_phy)"
  pattern can be simplified, considering that neither the IS_ERR() nor
  the NULL case continue execution in the current block. Therefore, we
  can move the case where the "utmi_phy" is a valid pointer outside the
  "if" checks, and this reduces the code indentation level.

[Severity: High]
If this fails, we jump to clean_up without updating the err variable. Since err
was initialized to 0, would this cause the driver probe to falsely report
success without having acquired the PHYs?

Could we assign err = index before the goto?

[Severity: Low]
This isn't a bug, but there is an extraneous newline before the colon in the
format string which will split the log message across two lines.

usb: host: tegra: avoid direct dereference of phy->dev.of_node

This commit removes direct access to phy->dev.of_node from the Tegra USB
host driver. It implements a parallel lookup path using the 'phys' phandle
to retrieve the OF node. The remote wake debug print is also updated to use
the PHY index instead.

[Severity: High]
This is a pre-existing issue, but does reusing a single struct notifier_block
(tegra->id_nb) across multiple independent USB PHYs corrupt their atomic
notifier chains?

Since tegra_xusb_init_usb_phy() loops over all available usb2 PHYs, it passes
the exact same &tegra->id_nb notifier block to devm_usb_get_phy_by_node().
usb_register_notifier() then links this same block into each PHY's independent
atomic_notifier_head, which overwrites its next pointer.

Could this lead to missed events or infinite loops when the lists are
traversed?

[Severity: High]
This isn't a bug introduced by this patch, but does the devres lifecycle
for this notifier create a use-after-free risk during driver removal?

In tegra_xusb_remove(), cancel_work_sync(&tegra->id_work) is called to
stop pending work, but the notifier remains registered until the devres
release phase via devm_usb_phy_release2().

If a USB PHY event fires in this window, tegra_xhci_id_notify() calls
schedule_work(). Devres then unregisters the notifier and frees the
tegra_xusb structure, causing the workqueue to dereference the freed
structure when it executes.
