Driver core changes for 6.4-rc1
Here is the large set of driver core changes for 6.4-rc1. Once again, a busy development cycle, with lots of changes happening in the driver core in the quest to be able to move "struct bus" and "struct class" into read-only memory, a task now complete with these changes. This will make the future rust interactions with the driver core more "provably correct" as well as providing more obvious lifetime rules for all busses and classes in the kernel. The changes required for this did touch many individual classes and busses as many callbacks were changed to take const * parameters instead. All of these changes have been submitted to the various subsystem maintainers, giving them plenty of time to review, and most of them actually did so. Other than those changes, included in here are a small set of other things: - kobject logging improvements - cacheinfo improvements and updates - obligatory fw_devlink updates and fixes - documentation updates - device property cleanups and const * changes - firwmare loader dependency fixes. All of these have been in linux-next for a while with no reported problems.

USB: core: Add routines for endpoint checks in old drivers
Many of the older USB drivers in the Linux USB stack were written based simply on a vendor's device specification. They use the endpoint information in the spec and assume these endpoints will always be present, with the properties listed, in any device matching the given vendor and product IDs. While that may have been true back then, with spoofing and fuzzing it is not true any more. More and more we are finding that those old drivers need to perform at least a minimum of checking before they try to use any endpoint other than ep0. To make this checking as simple as possible, we now add a couple of utility routines to the USB core. usb_check_bulk_endpoints() and usb_check_int_endpoints() take an interface pointer together with a list of endpoint addresses (numbers and directions). They check that the interface's current alternate setting includes endpoints with those addresses and that each of these endpoints has the right type: bulk or interrupt, respectively. Although we already have usb_find_common_endpoints() and related routines meant for a similar purpose, they are not well suited for this kind of checking. Those routines find endpoints of various kinds, but only one (either the first or the last) of each kind, and they don't verify that the endpoints' addresses agree with what the caller expects. In theory the new routines could be more general: They could take a particular altsetting as their argument instead of always using the interface's current altsetting. In practice I think this won't matter too much; multiple altsettings tend to be used for transferring media (audio or visual) over isochronous endpoints, not bulk or interrupt. Drivers for such devices will generally require more sophisticated checking than these simplistic routines provide.

USB: core: Add API to change the wireless_status

USB: core: Add wireless_status sysfs attribute
Add a wireless_status sysfs attribute to USB devices to keep track of whether a USB device that's comprised of a receiver dongle and an emitter device over a, most of the time proprietary, wireless link has its emitter connected or disconnected. This will be used by user-space OS components to determine whether the battery-powered part of the device is wirelessly connected or not, allowing, for example: - upower to hide the battery for devices where the device is turned off but the receiver plugged in, rather than showing 0%, or other values that could be confusing to users - Pipewire to hide a headset from the list of possible inputs or outputs or route audio appropriately if the headset is suddenly turned off, or turned on - libinput to determine whether a keyboard or mouse is present when its receiver is plugged in. This is done at the USB interface level as: - the interface on which the wireless status is detected is sometimes not the same as where it could be consumed (eg. the audio interface on a headset dongle will still appear even if the headset is turned off), and we cannot have synchronisation of status across subsystems. - this behaviour is not specific to HID devices, even if the protocols used to determine whether or not the remote device is connected can be HID. This is not an attribute that is meant to replace protocol specific APIs, such as the ones available for WWAN, WLAN/Wi-Fi, or Bluetooth or any other sort of networking, but solely for wireless devices with an ad-hoc “lose it and your device is e-waste” receiver dongle. The USB interface will only be exporting the wireless_status sysfs attribute if it gets set through the API exported in the next commit.

Driver core changes for 6.3-rc1
Here is the large set of driver core changes for 6.3-rc1.
There's a lot of changes this development cycle, most of the work falls
into two different categories:
- fw_devlink fixes and updates. This has gone through numerous review
cycles and lots of review and testing by lots of different devices.
Hopefully all should be good now, and Saravana will be keeping a
watch for any potential regression on odd embedded systems.
- driver core changes to work to make struct bus_type able to be moved
into read-only memory (i.e. const) The recent work with Rust has
pointed out a number of areas in the driver core where we are
passing around and working with structures that really do not have
to be dynamic at all, and they should be able to be read-only making
things safer overall. This is the contuation of that work (started
last release with kobject changes) in moving struct bus_type to be
constant. We didn't quite make it for this release, but the
remaining patches will be finished up for the release after this
one, but the groundwork has been laid for this effort.
Other than that we have in here:
- debugfs memory leak fixes in some subsystems
- error path cleanups and fixes for some never-able-to-be-hit
codepaths.
- cacheinfo rework and fixes
- Other tiny fixes, full details are in the shortlog
All of these have been in linux-next for a while with no reported
problems.

usb: core: hub: disable autosuspend for TI TUSB8041
The Texas Instruments TUSB8041 has an autosuspend problem at high temperature. If there is not USB traffic, after a couple of ms, the device enters in autosuspend mode. In this condition the external clock stops working, to save energy. When the USB activity turns on, ther hub exits the autosuspend state, the clock starts running again and all works fine. At ambient temperature all works correctly, but at high temperature, when the USB activity turns on, the external clock doesn't restart and the hub disappears from the USB bus. Disabling the autosuspend mode for this hub solves the issue.

Driver Core changes for 6.2-rc1
Here is the set of driver core and kernfs changes for 6.2-rc1. The "big" change in here is the addition of a new macro, container_of_const() that will preserve the "const-ness" of a pointer passed into it. The "problem" of the current container_of() macro is that if you pass in a "const *", out of it can comes a non-const pointer unless you specifically ask for it. For many usages, we want to preserve the "const" attribute by using the same call. For a specific example, this series changes the kobj_to_dev() macro to use it, allowing it to be used no matter what the const value is. This prevents every subsystem from having to declare 2 different individual macros (i.e. kobj_const_to_dev() and kobj_to_dev()) and having the compiler enforce the const value at build time, which having 2 macros would not do either. The driver for all of this have been discussions with the Rust kernel developers as to how to properly mark driver core, and kobject, objects as being "non-mutable". The changes to the kobject and driver core in this pull request are the result of that, as there are lots of paths where kobjects and device pointers are not modified at all, so marking them as "const" allows the compiler to enforce this. So, a nice side affect of the Rust development effort has been already to clean up the driver core code to be more obvious about object rules. All of this has been bike-shedded in quite a lot of detail on lkml with different names and implementations resulting in the tiny version we have in here, much better than my original proposal. Lots of subsystem maintainers have acked the changes as well. Other than this change, included in here are smaller stuff like: - kernfs fixes and updates to handle lock contention better - vmlinux.lds.h fixes and updates - sysfs and debugfs documentation updates - device property updates All of these have been in the linux-next tree for quite a while with no problems, OTHER than some merge issues with other trees that should be obvious when you hit them (block tree deletes a driver that this tree modifies, iommufd tree modifies code that this tree also touches).

- removal of the sisusbvga driver that was not used by anyone anymore
- minor thunderbolt driver changes and tweaks
- chipidea driver updates
- usual set of typec driver features and hardware support added
- musb minor driver fixes
- fotg210 driver fixes, bringing that hardware back from the "dead"
- minor dwc3 driver updates
- addition, and then removal, of a list.h helper function for many USB
and other subsystem drivers, that ended up breaking the build. That
will come back for 6.3-rc1, it missed this merge window.
- usual xhci updates and enhancements
- usb-serial driver updates and support for new devices
- other minor USB driver updates
All of these have been in linux-next for a while with no reported

xhci: disable U3 suspended ports in S4 hibernate poweroff_late stage
Disable U3 suspended ports in hibernate S4 poweroff_late for systems with XHCI_RESET_TO_DEFAULT quirk, if wakeup is not enabled. This reduces the number of self-powered usb devices from surviving in U3 suspended state into next reboot. Bootloader/firmware on these systems can't handle usb ports in U3, and will timeout, causing extra delay during reboot/restore from S4. Add pci_poweroff_late() callback to struct usb_hcd to get this done at the correct stage in hibernate.

The devnode() in struct class should not be modifying the device that is passed into it, so mark it as a const * and propagate the function signature changes out into all relevant subsystems that use this callback.

usb: add NO_LPM quirk for Realforce 87U Keyboard
Before adding this quirk, this (mechanical keyboard) device would not be recognized, logging: new full-speed USB device number 56 using xhci_hcd unable to read config index 0 descriptor/start: -32 chopping to 0 config(s) It would take dozens of plugging/unpuggling cycles for the keyboard to be recognized. Keyboard seems to simply work after applying this quirk. This issue had been reported by users in two places already ([1], [2]) but nobody tried upstreaming a patch yet. After testing I believe their suggested fix (DELAY_INIT + NO_LPM + DEVICE_QUALIFIER) was probably a little overkill. I assume this particular combination was tested because it had been previously suggested in [3], but only NO_LPM seems sufficient for this device.

usb: core: stop USB enumeration if too many retries
When a broken USB accessory connects to a USB host, usbcore might keep doing enumeration retries. If the host has a watchdog mechanism, the kernel panic will happen on the host. This patch provides an attribute early_stop to limit the numbers of retries for each port of a hub. If a port was marked with early_stop attribute, unsuccessful connection attempts will fail quickly. In addition, if an early_stop port has failed to initialize, it will ignore all future connection events until early_stop attribute is clear.

USB: core: Change configuration warnings to notices
It has been pointed out that the kernel log messages warning about problems in USB configuration and related descriptors are vexing for users. The warning log level has a fairly high priority, but the user can do nothing to fix the underlying errors in the device's firmware. To reduce the amount of useless information produced by tools that filter high-priority log messages, we can change these warnings to notices, i.e., change dev_warn() to dev_notice(). The same holds for a few messages that currently use dev_err(): Unless they indicate a failure that might make a device unusable (such as inability to transfer a config descriptor), change them to dev_notice() also.

usb: add quirks for Lenovo OneLink+ Dock
The Lenovo OneLink+ Dock contains two VL812 USB3.0 controllers:
17ef:1018 upstream
17ef:1019 downstream
These hubs suffer from two separate problems:
1) After the host system was suspended and woken up, the hubs appear to
be in a random state. Some downstream ports (both internal to the
built-in audio and network controllers, and external to USB sockets)
may no longer be functional. The exact list of disabled ports (if
any) changes from wakeup to wakeup. Ports remain in that state until
the dock is power-cycled, or until the laptop is rebooted.
Wakeup sources connected to the hubs (keyboard, WoL on the integrated
gigabit controller) will wake the system up from suspend, but they
may no longer work after wakeup (and in that case will no longer work
as wakeup source in a subsequent suspend-wakeup cycle).
This issue appears in the logs with messages such as:
usb 1-6.1-port4: cannot disable (err = -71)
usb 1-6-port2: cannot disable (err = -71)
usb 1-6.1: clear tt 1 (80c0) error -71
usb 1-6-port4: cannot disable (err = -71)
usb 1-6.4: PM: dpm_run_callback(): usb_dev_resume+0x0/0x10 [usbcore] returns -71
usb 1-6.4: PM: failed to resume async: error -71
usb 1-7: reset full-speed USB device number 5 using xhci_hcd
usb 1-6.1-port1: cannot reset (err = -71)
usb 1-6.1-port1: cannot reset (err = -71)
usb 1-6.1-port1: cannot reset (err = -71)
usb 1-6.1-port1: cannot reset (err = -71)
usb 1-6.1-port1: cannot reset (err = -71)
usb 1-6.1-port1: Cannot enable. Maybe the USB cable is bad?
usb 1-6.1-port1: cannot disable (err = -71)
usb 1-6.1-port1: cannot reset (err = -71)
usb 1-6.1-port1: cannot reset (err = -71)
usb 1-6.1-port1: cannot reset (err = -71)
usb 1-6.1-port1: cannot reset (err = -71)
usb 1-6.1-port1: cannot reset (err = -71)
usb 1-6.1-port1: Cannot enable. Maybe the USB cable is bad?
usb 1-6.1-port1: cannot disable (err = -71)
2) Some USB devices cannot be enumerated properly. So far I have only
seen the issue with USB 3.0 devices. The same devices work without
problem directly connected to the host system, to other systems or to
other hubs (even when those hubs are connected to the OneLink+ dock).
One very reliable reproducer is this USB 3.0 HDD enclosure:
152d:9561 JMicron Technology Corp. / JMicron USA Technology Corp. Mobius
I have seen it happen sporadically with other USB 3.0 enclosures,
with controllers from different manufacturers, all self-powered.
Typical messages in the logs:
xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command
xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command
usb 2-1.4: device not accepting address 6, error -62
xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command
xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command
usb 2-1.4: device not accepting address 7, error -62
usb 2-1-port4: attempt power cycle
xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command
xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command
usb 2-1.4: device not accepting address 8, error -62
xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command
xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command
usb 2-1.4: device not accepting address 9, error -62
usb 2-1-port4: unable to enumerate USB device
Through trial and error, I found that the USB_QUIRK_RESET_RESUME solved
the second issue. Further testing then uncovered the first issue. Test
results are summarized in this table:
=======================================================================================
Settings USB2 hotplug USB3 hotplug State after waking up
---------------------------------------------------------------------------------------
power/control=auto works fails broken
usbcore.autosuspend=-1 works works broken
OR power/control=on
power/control=auto works (1) works (1) works
and USB_QUIRK_RESET_RESUME
power/control=on works works works
and USB_QUIRK_RESET_RESUME
HUB_QUIRK_DISABLE_AUTOSUSPEND works works works
and USB_QUIRK_RESET_RESUME
=======================================================================================
In those results, the power/control settings are applied to both hubs,
both on the USB2 and USB3 side, before each test.
From those results, USB_QUIRK_RESET_RESUME is required to reset the hubs
properly after a suspend-wakeup cycle, and the hubs must not autosuspend
to work around the USB3 issue.
A secondary effect of USB_QUIRK_RESET_RESUME is to prevent the hubs'
upstream links from suspending (the downstream ports can still suspend).
This secondary effect is used in results (1). It is enough to solve the
USB3 problem.
Setting USB_QUIRK_RESET_RESUME on those hubs is the smallest patch that
solves both issues.
Prior to creating this patch, I have used the USB_QUIRK_RESET_RESUME via
the kernel command line for over a year without noticing any side
effect.
Thanks to Oliver Neukum @Suse for explanations of the operations of
USB_QUIRK_RESET_RESUME, and requesting more testing.

That is, as the rtl8712 driver was being unbound from a composite device in preparation for an unrelated USB reset (that driver does not have pre_reset or post_reset callbacks), its ->remove routine called usb_reset_device() -- thus nesting one reset call within another. Performing a reset as part of disconnect processing is a questionable practice at best. However, the bug report points out that the USB core does not have any protection against nested resets. Adding a reset_in_progress flag and testing it will prevent such errors in the future.

usb: add quirks for Lenovo OneLink+ Dock
The Lenovo OneLink+ Dock contains two VL812 USB3.0 controllers: 17ef:1018 upstream 17ef:1019 downstream Those two controllers both have problems with some USB3.0 devices, particularly self-powered ones. Typical error messages include: Timeout while waiting for setup device command device not accepting address X, error -62 unable to enumerate USB device By process of elimination the controllers themselves were identified as the cause of the problem. Through trial and error the issue was solved by using USB_QUIRK_RESET_RESUME for both chips.

USB / Thunderbolt changes for 6.0-rc1
Here is the big set of Thunderbolt and USB changes for 6.0-rc1.
Lots of little things here, nothing major, just constant development on
some new hardware support and cleanups of older drivers. Highlights of
this pull request are:
- lots of typec changes and improvements for new hardware
- new gadget controller driver
- thunderbolt support for new hardware
- the normal set of new usb-serial device ids and cleanups
- loads of dwc3 controller fixes and improvements
- mtu3 driver updates
- testusb fixes for longtime issues (not many people use this
tool it seems.)
- minor driver fixes and improvements over the USB tree
- chromeos platform driver changes were added and then reverted
as they depened on some typec changes, but the cross-tree
merges caused problems so they will come back later through
the platform tree.
All of these have been in linux-next for a while now with no reported
issues.
