git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core Pull driver core updates from Greg KH: "Here is the big set of driver core changes for 6.11-rc1. Lots of stuff in here, with not a huge diffstat, but apis are evolving which required lots of files to be touched. Highlights of the changes in here are: - platform remove callback api final fixups (Uwe took many releases to get here, finally!) - Rust bindings for basic firmware apis and initial driver-core interactions. It's not all that useful for a "write a whole driver in rust" type of thing, but the firmware bindings do help out the phy rust drivers, and the driver core bindings give a solid base on which others can start their work. There is still a long way to go here before we have a multitude of rust drivers being added, but it's a great first step. - driver core const api changes. This reached across all bus types, and there are some fix-ups for some not-common bus types that linux-next and 0-day testing shook out. This work is being done to help make the rust bindings more safe, as well as the C code, moving toward the end-goal of allowing us to put driver structures into read-only memory. We aren't there yet, but are getting closer. - minor devres cleanups and fixes found by code inspection - arch_topology minor changes - other minor driver core cleanups All of these have been in linux-next for a very long time with no reported problems" * tag 'driver-core-6.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (55 commits) ARM: sa1100: make match function take a const pointer sysfs/cpu: Make crash_hotplug attribute world-readable dio: Have dio_bus_match() callback take a const * zorro: make match function take a const pointer driver core: module: make module_[add|remove]_driver take a const * driver core: make driver_find_device() take a const * driver core: make driver_[create|remove]_file take a const * firmware_loader: fix soundness issue in `request_internal` firmware_loader: annotate doctests as `no_run` devres: Correct code style for functions that return a pointer type devres: Initialize an uninitialized struct member devres: Fix memory leakage caused by driver API devm_free_percpu() devres: Fix devm_krealloc() wasting memory driver core: platform: Switch to use kmemdup_array() driver core: have match() callback in struct bus_type take a const * MAINTAINERS: add Rust device abstractions to DRIVER CORE device: rust: improve safety comments MAINTAINERS: add Danilo as FIRMWARE LOADER maintainer MAINTAINERS: add Rust FW abstractions to FIRMWARE LOADER firmware: rust: improve safety comments ...
2024-07-25of: remove internal arguments from of_property_for_each_u32()Luca Ceresoli
The of_property_for_each_u32() macro needs five parameters, two of which are primarily meant as internal variables for the macro itself (in the for() clause). Yet these two parameters are used by a few drivers, and this can be considered misuse or at least bad practice. Now that the kernel uses C11 to build, these two parameters can be avoided by declaring them internally, thus changing this pattern: struct property *prop; const __be32 *p; u32 val; of_property_for_each_u32(np, "xyz", prop, p, val) { ... } to this: u32 val; of_property_for_each_u32(np, "xyz", val) { ... } However two variables cannot be declared in the for clause even with C11, so declare one struct that contain the two variables we actually need. As the variables inside this struct are not meant to be used by users of this macro, give the struct instance the noticeable name "_it" so it is visible during code reviews, helping to avoid new code to use it directly. Most usages are trivially converted as they do not use those two parameters, as expected. The non-trivial cases are: - drivers/clk/clk.c, of_clk_get_parent_name(): easily doable anyway - drivers/clk/clk-si5351.c, si5351_dt_parse(): this is more complex as the checks had to be replicated in a different way, making code more verbose and somewhat uglier, but I refrained from a full rework to keep as much of the original code untouched having no hardware to test my changes All the changes have been build tested. The few for which I have the hardware have been runtime-tested too.

2024-07-10usb: gadget: f_uac2: fix non-newline-terminated function nameJohn Keeping
Most writes to configfs handle an optional newline, but do not require it. By using the number of bytes written as the limit for scnprintf() it is guaranteed that the final character in the buffer will be overwritten. This is expected if it is a newline but is undesirable when a string is written "as-is" (as libusbgx does, for example). Update the store function to strip an optional newline, matching the behaviour of usb_string_copy().

2024-07-10usb: dwc3: enable CCI support for AMD-xilinx DWC3 controllerRadhey Shyam Pandey
The GSBUSCFG0 register bits [31:16] are used to configure the cache type settings of the descriptor and data write/read transfers (Cacheable, Bufferable/Posted). When CCI is enabled in the design, DWC3 core GSBUSCFG0 cache bits must be updated to support CCI enabled transfers in USB. To program GSBUSCFG0 cache bits create a software node property in AMD-xilinx dwc3 glue driver and pass it to dwc3 core. The core then reads this property value and configures it in dwc3_core_init() sequence.

2024-07-09USB: serial: mos7840: fix crash on resumeDmitry Smirnov
Since commit c49cfa917025 ("USB: serial: use generic method if no alternative is provided in usb serial layer"), USB serial core calls the generic resume implementation when the driver has not provided one. This can trigger a crash on resume with mos7840 since support for multiple read URBs was added back in 2011. Specifically, both port read URBs are now submitted on resume for open ports, but the context pointer of the second URB is left set to the core rather than mos7840 port structure. Fix this by implementing dedicated suspend and resume functions for mos7840. Tested with Delock 87414 USB 2.0 to 4x serial adapter.

Userspace provided string 's' could trivially have the length zero. Left unchecked this will firstly result in an OOB read in the form `if (str[0 - 1] == '\n') followed closely by an OOB write in the form `str[0 - 1] = '\0'`. There is already a validating check to catch strings that are too long. Let's supply an additional check for invalid strings that are too short.

2024-07-03USB: core: Fix duplicate endpoint bug by clearing reserved bits in the ↵Alan Stern
descriptor Syzbot has identified a bug in usbcore (see the Closes: tag below) caused by our assumption that the reserved bits in an endpoint descriptor's bEndpointAddress field will always be 0. As a result of the bug, the endpoint_is_duplicate() routine in config.c (and possibly other routines as well) may believe that two descriptors are for distinct endpoints, even though they have the same direction and endpoint number. This can lead to confusion, including the bug identified by syzbot (two descriptors with matching endpoint numbers and directions, where one was interrupt and the other was bulk). To fix the bug, we will clear the reserved bits in bEndpointAddress when we parse the descriptor. (Note that both the USB-2.0 and USB-3.1 specs say these bits are "Reserved, reset to zero".) This requires us to make a copy of the descriptor earlier in usb_parse_endpoint() and use the copy instead of the original when checking for duplicates.

2024-07-03xhci: always resume roothubs if xHC was reset during resumeMathias Nyman
Usb device connect may not be detected after runtime resume if xHC is reset during resume. In runtime resume cases xhci_resume() will only resume roothubs if there are pending port events. If the xHC host is reset during runtime resume due to a Save/Restore Error (SRE) then these pending port events won't be detected as PORTSC change bits are not immediately set by host after reset. Unconditionally resume roothubs if xHC is reset during resume to ensure device connections are detected. Also return early with error code if starting xHC fails after reset. Issue was debugged and a similar solution suggested by Remi Pommarel. Using this instead as it simplifies future refactoring.

2024-07-03driver core: have match() callback in struct bus_type take a const *Greg Kroah-Hartman
In the match() callback, the struct device_driver * should not be changed, so change the function callback to be a const *. This is one step of many towards making the driver core safe to have struct device_driver in read-only memory. Because the match() callback is in all busses, all busses are modified to handle this properly. This does entail switching some container_of() calls to container_of_const() to properly handle the constant *. For some busses, like PCI and USB and HV, the const * is cast away in the match callback as those busses do want to modify those structures at this point in time (they have a local lock in the driver structure.) That will have to be changed in the future if they wish to have their struct device * in read-only-memory. Cc: Rafael J.

2024-06-27usb: dwc3: core: Workaround for CSR read timeoutJos Wang
This is a workaround for STAR 4846132, which only affects DWC_usb31 version2.00a operating in host mode. There is a problem in DWC_usb31 version 2.00a operating in host mode that would cause a CSR read timeout When CSR read coincides with RAM Clock Gating Entry. By disable Clock Gating, sacrificing power consumption for normal operation.

2024-06-27Revert "usb: gadget: u_ether: Replace netif_stop_queue with netif_device_detach"Ferry Toth
This reverts commit f49449fbc21e7e9550a5203902d69c8ae7dfd918. This commit breaks u_ether on some setups (at least Merrifield). The fix "usb: gadget: u_ether: Re-attach netif device to mirror detachment" party restores u-ether. However the netif usb: remains up even usb is switched from device to host mode. This creates problems for user space as the interface remains in the routing table while not realy present and network managers (connman) not detecting a network change. Various attempts to find the root cause were unsuccesful up to now. Therefore revert until a solution is found.

2024-06-27xhci: sort out TRB Endpoint ID bitfield macrosMathias Nyman
xhci macros that read and write endpoint ID bitfields of TRBs are mixing the 1-based Endpoint ID as described in the xHCI specification, and 0-based endpoint index used by driver as an array index. Sort this out by naming macros that deal with 1 based Endpoint ID fields to *_EP_ID_*, and 0 based endpoint index values to *_EP_INDEX_*.

2024-06-27xhci: Apply XHCI_RESET_TO_DEFAULT quirk to TGLReka Norman
TGL systems have the same issue as ADL, where a large boot firmware delay is seen if USB ports are left in U3 at shutdown. So apply the XHCI_RESET_TO_DEFAULT quirk to TGL as well. The issue it fixes is a ~20s boot time delay when booting from S5. It affects TGL devices, and TGL support was added starting from v5.3.

2024-06-27usb: xhci: remove infinite loop preventionNiklas Neronin
If a buggy HW reports some unpredicted event (for example, an overrun event following a MSE event while the EP ring is actually not empty), the driver will never find the TD, and it will loop until the TD list is empty. Before commits [1][2], the spin lock was released when giving back a URB in the do-while loop. This could cause more TD to be added to TD list, causing an infinite loop. Because of commits [1][2] the spin lock is not released any more, thus the infinite loop prevention is unnecessary and is removed. [1], commit 0c03d89d0c71 ("xhci: Giveback urb in finish_td directly") [2], commit 36dc01657b49 ("usb: host: xhci: Support running urb giveback in tasklet context") Signed-off-by: Niklas Neronin <niklas.neronin@linux.intel.com> Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> Link: https://lore.kernel.org/r/20240626124835.1023046-18-mathias.nyman@linux.intel.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2024-06-27usb: xhci: ensure skipped isoc TDs are returned when isoc ring is stoppedNiklas Neronin
Missed service event tells the driver that the hardware wasn't able to process some queued isoc TDs in their right time slots, and some TDs will be skipped. The driver sets a 'skip' flag to indicate that the next transfer event after this event will point to some future TD instead of the next queued TD. Once the driver receives the next event, it will skip and give back all those hardware skipped TDs. However, should this subsequent event be a stop endpoint which does not point to the next pending TD, the driver fails to return the skipped TDs. Instead, it loops for a period before outputting an erroneous message. Fix this by repositioning the 'stop endpoint' check to follow the isoc skip check, ensuring the skipped TDs are properly returned.
