2025-06-24usb: typec: altmodes/displayport: do not index invalid pin_assignmentsRD Babiera
A poorly implemented DisplayPort Alt Mode port partner can indicate that its pin assignment capabilities are greater than the maximum value, DP_PIN_ASSIGN_F. In this case, calls to pin_assignment_show will cause a BRK exception due to an out of bounds array access. Prevent for loop in pin_assignment_show from accessing invalid values in pin_assignments by adding DP_PIN_ASSIGN_MAX value in typec_dp.h and using i < DP_PIN_ASSIGN_MAX as a loop condition.

In the case of handling a USB bus reset, the xhci_discover_or_reset_device can run without first notifying the xHCI sideband client driver to stop or prevent the use of the transfer ring.

Introduce XHCI sideband, which manages the USB endpoints being requested by a client driver. This is used for when client drivers are attempting to offload USB endpoints to another entity for handling USB transfers. XHCI sec intr will allow for drivers to fetch the required information about the transfer ring, so the user can submit transfers independently. Expose the required APIs for drivers to register and request for a USB endpoint and to manage XHCI secondary interrupters.

2025-01-17usb: typec: tcpci: Prevent Sink disconnection before vPpsShutdown in SPR PPSKyle Tso
The Source can drop its output voltage to the minimum of the requested PPS APDO voltage range when it is in Current Limit Mode. If this voltage falls within the range of vPpsShutdown, the Source initiates a Hard Reset and discharges Vbus. However, currently the Sink may disconnect before the voltage reaches vPpsShutdown, leading to unexpected behavior. Prevent premature disconnection by setting the Sink's disconnect threshold to the minimum vPpsShutdown value. Additionally, consider the voltage drop due to IR drop when calculating the appropriate threshold. This ensures a robust and reliable interaction between the Source and Sink during SPR PPS Current Limit Mode operation.

2024-10-04usb: chipidea: add CI_HDRC_HAS_SHORT_PKT_LIMIT flagXu Yang
Currently, the imx deivice controller has below limitations: 1. can't generate short packet interrupt if IOC not set in dTD. So if one request span more than one dTDs and only the last dTD set IOC, the usb request will pending there if no more data comes. 2. the controller can't accurately deliver data to differtent usb requests in some cases due to short packet. For example: one usb request span 3 dTDs, then if the controller received a short packet the next packet will go to 2nd dTD of current request rather than the first dTD of next request. 3. can't build a bus packet use multiple dTDs. For example: controller needs to send one packet of 512 bytes use dTD1 (200 bytes) + dTD2 (312 bytes), actually the host side will see 200 bytes short packet. Based on these limits, add CI_HDRC_HAS_SHORT_PKT_LIMIT flag and use it on imx platforms.

2024-08-26USB: serial: set driver owner when registering driversKrzysztof Kozlowski
Modules registering drivers with usb_serial_register_drivers() might forget to set .owner field. The field is used by some of other kernel parts for reference counting (try_module_get()), so it is expected that drivers will set it. Solve the problem by moving this task away from the drivers to the core USB serial code, just like we did for platform_driver in commit 9447057eaff8 ("platform_device: use a macro instead of platform_driver_register").

'struct config_item_type' is not modified in this file. Apparently, these structures are only used with config_group_init_type_name() which takes a const struct config_item_type* as a 3rd argument. Constifying this structure moves some data to a read-only section, so increase overall security, especially when the structure holds some function pointers.

2024-07-10usb: gadget: Use u16 types for 16-bit fieldsKees Cook
Since the beginning of time, struct usb_ep::maxpacket was a bitfield, and when new 16-bit members were added, the convention was followed: 1da177e4c3f41 (Linus Torvalds 2005-04-16 236) unsigned maxpacket:16; e117e742d3106 (Robert Baldyga 2013-12-13 237) unsigned maxpacket_limit:16; a59d6b91cbca5 (Tatyana Brokhman 2011-06-28 238) unsigned max_streams:16; However, there is no need for this as a simple u16 can be used instead, simplifying the struct and the resulting compiler binary output. Switch to u16 for all three, and rearrange struct slightly to minimize holes. No change in the final size of the struct results; the 2 byte gap is just moved to the end, as seen with pahole: - /* XXX 2 bytes hole, try to pack */ ... /* size: 72, cachelines: 2, members: 15 */ ... + /* padding: 2 */ Changing this simplifies future introspection[1] of maxpacket's type during allocations: drivers/usb/gadget/function/f_tcm.c:330:24: error: 'typeof' applied to a bit-field 330 | fu->cmd.buf = kmalloc(fu->ep_out->maxpacket, GFP_KERNEL); Link: https://lore.kernel.org/all/202407090928.6UaOAZAJ-lkp@intel.com [1] Signed-off-by: Kees Cook <kees@kernel.org> Link: https://lore.kernel.org/r/20240709154953.work.953-kees@kernel.org Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

This patch prepares onboad_hub to support non-hub devices by renaming the driver files and their content, the headers and their references. The comments and descriptions have been slightly modified to keep coherence and account for the specific cases that only affect onboard hubs (e.g. peer-hub). The "hub" variables in functions where "dev" (and similar names) variables already exist have been renamed to onboard_dev for clarity, which adds a few lines in cases where more than 80 characters are used. No new functionality has been added.
