[PATCH v2 2/2] usb: dwc3: Force full reset on xhci removal

by Roy Luo

During an xhci host controller reset (via `USBCMD.HCRST`), reading DWC3 registers can return zero instead of their actual values. This applies not only to registers within the xhci memory space but also those in the broader DWC3 IP block. By default, the xhci driver doesn't wait for the reset handshake to complete during teardown. This can cause problems when the DWC3 controller is operating as a dual role device and is switching from host to device mode, the invalid register read caused by ongoing HCRST could lead to gadget mode startup failures and unintended register overwrites. To mitigate this, enable xhci-full-reset-on-remove-quirk to ensure that xhci_reset() completes its full reset handshake during xhci removal.

[PATCH] drm: radeon: ci_dpm: Add error handling for ci_send_msg_to_smc_with_parameter()

by Wentao Liang

The ci_enable_uvd_dpm() calls ci_send_msg_to_smc_with_parameter() but does not check the return value. This could lead to the execution with potentially invalid data. A proper implementation can be found in the ci_fan_ctrl_start_smc_fan_control(). Add a check after calling ci_send_msg_to_smc_with_parameter(), return -EINVAL if the sending fails.

[PATCH] arm64: Check pxd_leaf() instead of !pxd_table() while tearing down page tables

by Dev Jain

Commit 9c006972c3fe removes the pxd_present() checks because the caller checks pxd_present(). But, in case of vmap_try_huge_pud(), the caller only checks pud_present(); pud_free_pmd_page() recurses on each pmd through pmd_free_pte_page(), wherein the pmd may be none. Thus it is possible to hit a warning in the latter, since pmd_none => !pmd_table(). Thus, enforce these checks again through pxd_leaf(). This problem was found by code inspection. The patch is based on 6.15-rc6.

[PATCH v2 0/5] Fix onboard USB hub instability on RK3399 Puma SoM

by Lukasz Czechowski

The RK3399 Puma SoM contains the internal Cypress CYUSB3304 USB hub, that shows instability due to improper reset pin configuration. Currently reset pin is modeled as a vcc5v0_host regulator, that might result in too short reset pulse duration. Starting with the v6.6, the Onboard USB hub driver (later renamed to Onboard USB dev) contains support for Cypress HX3 hub family. It can be now used to correctly model the RK3399 Puma SoM hardware. The first commits in this series fix the onboard USB dev driver to support all HX3 hub variants, including the CYUSB3304 found in the RK3399 Puma SoM. This allows to introduce fix for internal USB hub instability on RK3399 Puma, by replacing the vcc5v0_host regulator with cy3304_reset, used inside the hub node. Please be aware that the patch that fixes USB hub instability in arch/arm64/boot/dts/rockchip/rk3399-puma.dtsi can me merged only after updating the Onboard USB dev driver, otherwise the hub will not work. Two last commits in the series disable unrouted USB controllers and PHYs on RK3399 Puma SOM and Haikou carrier board, with no intended functional changes.

[PATCH] platform/x86: dell-wmi-sysman: Avoid buffer overflow in current_password_store()

by Vladimir Moskovkin

If the 'buf' array received from the user contains an empty string, the 'length' variable will be zero. Accessing the 'buf' array element with index 'length - 1' will result in a buffer overflow. Add a check for an empty string. Found by Linux Verification Center (linuxtesting.org) with SVACE.

[PATCH net 0/5] hv_netvsc: Fix error "nvsp_rndis_pkt_complete error status: 2"

by mhkelley58＠gmail.com

From: Michael Kelley <mhklinux(a)outlook.com> Starting with commit dca5161f9bd0 in the 6.3 kernel, the Linux driver for Hyper-V synthetic networking (netvsc) occasionally reports "nvsp_rndis_pkt_complete error status: 2".[1] This error indicates that Hyper-V has rejected a network packet transmit request from the guest, and the outgoing network packet is dropped. Higher level network protocols presumably recover and resend the packet so there is no functional error, but performance is slightly impacted. Commit dca5161f9bd0 is not the cause of the error -- it only added reporting of an error that was already happening without any notice. The error has presumably been present since the netvsc driver was originally introduced into Linux. This patch set fixes the root cause of the problem, which is that the netvsc driver in Linux may send an incorrectly formatted VMBus message to Hyper-V when transmitting the network packet. The incorrect formatting occurs when the rndis header of the VMBus message crosses a page boundary due to how the Linux skb head memory is aligned. In such a case, two PFNs are required to describe the location of the rndis header, even though they are contiguous in guest physical address (GPA) space. Hyper-V requires that two PFNs be in a single "GPA range" data struture, but current netvsc code puts each PFN in its own GPA range, which Hyper-V rejects as an error in the case of the rndis header. The incorrect formatting occurs only for larger packets that netvsc must transmit via a VMBus "GPA Direct" message. There's no problem when netvsc transmits a smaller packet by copying it into a pre- allocated send buffer slot because the pre-allocated slots don't have page crossing issues. After commit 14ad6ed30a10 in the 6.14 kernel, the error occurs much more frequently in VMs with 16 or more vCPUs. It may occur every few seconds, or even more frequently, in a ssh session that outputs a lot of text. Commit 14ad6ed30a10 subtly changes how skb head memory is allocated, making it much more likely that the rndis header will cross a page boundary when the vCPU count is 16 or more. The changes in commit 14ad6ed30a10 are perfectly valid -- they just had the side effect of making the netvsc bug more prominent. One fix is to check for adjacent PFNs in vmbus_sendpacket_pagebuffer() and just combine them into a single GPA range. Such a fix is very contained. But conceptually it is fixing the problem at the wrong level. So this patch set takes the broader approach of maintaining the already known grouping of contiguous PFNs at a higher level in the netvsc driver code, and propagating that grouping down to the creation of the VMBus message to send to Hyper-V. Maintaining the grouping fixes this problem, and has the added benefit of allowing netvsc_dma_map() to make fewer calls to dma_map_single() to do bounce buffering in CoCo VMs. Patch 1 is a preparatory change to allow vmbus_sendpacket_mpb_desc() to specify multiple GPA ranges. In current code vmbus_sendpacket_mpb_desc() is used only by the storvsc synthetic SCSI driver, and it always creates a single GPA range. Patch 2 updates the netvsc driver to use vmbus_sendpacket_mpb_desc() instead of vmbus_sendpacket_pagebuffer(). Because the higher levels of netvsc still don't group contiguous PFNs, this patch is functionally neutral. The VMBus message to Hyper-V still has many GPA ranges, each with a single PFN. But it lays the groundwork for the next patch. Patch 3 changes the higher levels of netvsc to preserve the already known grouping of contiguous PFNs. When the contiguous groupings are passed to vmbus_sendpacket_mpb_desc(), GPA ranges containing multiple PFNs are produced, as expected by Hyper-V. This is point at which the core problem is fixed. Patches 4 and 5 remove code that is no longer necessary after the previous patches. These changes provide a net reduction of about 65 lines of code, which is an added benefit. These changes have been tested in normal VMs, in SEV-SNP and TDX CoCo VMs, and in Dv6-series VMs where the netvsp implementation is in the OpenHCL paravisor instead of the Hyper-V host. These changes are built against kernel version 6.15-rc6.

[PATCH] ALSA: usb-audio: Add sample rate quirk for Microdia JP001 USB Camera

Microdia JP001 does not support reading the sample rate which leads to many lines of "cannot get freq at ep 0x84".
