2023-06-13md/raid5: don't allow replacement while reshape is in progressYu Kuai
If reshape is interrupted(for example, echo frozen to sync_action), then rdev replacement can be set. It's safe because reshape is always prior to resync in md_check_recovery(). However, if system reboots, then kernel will complain cannot handle concurrent replacement and reshape and this array is not able to assemble anymore. Fix this problem by don't allow replacement until reshape is done.

2023-06-13md/raid10: check slab-out-of-bounds in md_bitmap_get_counterLi Nan
If we write a large number to md/bitmap_set_bits, md_bitmap_checkpage() will return -EINVAL because 'page >= bitmap->pages', but the return value was not checked immediately in md_bitmap_get_counter() in order to set *blocks value and slab-out-of-bounds occurs.

2023-06-13nios2: Replace all non-returning strlcpy with strscpyAzeem Shaikh
strlcpy() reads the entire source buffer first. This read may exceed the destination size limit. This is both inefficient and can lead to linear read overflows if a source string is not NUL-terminated [1]. In an effort to remove strlcpy() completely [2], replace strlcpy() here with strscpy(). No return values were used, so direct replacement is safe.

2023-06-13Revert "drm/amdgpu: remove TOPDOWN flags when allocating VRAM in large bar ↵Arunpravin Paneer Selvam
system" This reverts commit c105518679b6e87232874ffc989ec403bee59664. This patch disables the TOPDOWN flag for APU and few dGPU cards which has the VRAM size equal to the BAR size. When we enable the TOPDOWN flag, we get the free blocks at the highest available memory region and we don't split the lower order blocks. This change is required to keep off the fragmentation related issues particularly in ASIC which has VRAM space <= 500MiB Hence, we are reverting this patch.

2023-06-13drm/amdgpu: Reset CP_VMID_PREEMPT after trailing fence signaledJiadong Zhu
When MEC executes unmap_queue for mid command buffer preemption, it will kick the write pointer of the gfx ring, set CP_VMID_PREEMPT to trigger the preemption and wait for CP_VMID_PREEMPT becomes zero after the preemption done. There is a race condition that PFP may excute the resetting command before MEC set CP_VMID_PREEMPT. As a result, hang happens as CP_VMID_PREEMPT is always 0xffff. To avoid this, we send resetting CP_VMID_PREEMPT command after the trailing fence is siganled and update gfx write pointer explicitly.

2023-06-13thermal: intel: int340x_thermal: New IOCTLs for Passive v2 tableSrinivas Pandruvada
Export Passive version 2 table similar to the way _TRT and _ART tables via IOCTLs. This removes need for binary utility to read ACPI Passive 2 table by providing open source support. This table already has open source implementation in the user space thermald, when the table is part of data vault exported by the int3400 sysfs. This table is supported in some older platforms before Ice Lake generation. Passive 2 tables contain multiple entries. Each entry has following fields: * Source: Named Reference (String). This is the source device for temperature. * Target: Named Reference (String). This is the target device to control. * Priority: Priority of this device compared to others. * SamplingPeriod: Time Period in 1/10 of seconds unit. * PassiveTemp: Passive Temperature in 1/10 of Kelvin. * SourceDomain: Domain for the source (00:Processor, others reserved). * ControlKnob: Type of control knob (00:Power Limit 1, others: reserved) * Limit: The target state to set on reaching passive temperature. This can be a string "max", "min" or a power limit value. * LimitStepSize: Step size during activation. * UnLimitStepSize: Step size during deactivation. * Reserved1: Reserved Three IOCTLs are added similar to IOCTLs for reading TRT: ACPI_THERMAL_GET_PSVT_COUNT: Number of passive 2 entries. ACPI_THERMAL_GET_PSVT_LEN: Total return data size (count x each passive 2 entry size). ACPI_THERMAL_GET_PSVT: Get the data as an array of objects with passive 2 entries.

2023-06-13regmap: regcache: Don't sync read-only registersTakashi Iwai
regcache_maple_sync() tries to sync all cached values no matter whether it's writable or not. OTOH, regache_sync_val() does care the wrtability and returns -EIO for a read-only register. This results in an error message like: snd_hda_codec_realtek hdaudioC0D0: Unable to sync register 0x2f0009. -5 and the sync loop is aborted incompletely. This patch adds the writable register check to regcache_sync_val() for addressing the bug above.

2023-06-13drm/nouveau: don't detect DSM for non-NVIDIA deviceRatchanan Srirattanamet
The call site of nouveau_dsm_pci_probe() uses single set of output variables for all invocations. So, we must not write anything to them unless it's an NVIDIA device. Otherwise, if we are called with another device after the NVIDIA device, we'll clober the result of the NVIDIA device. For example, if the other device doesn't have _PR3 resources, the detection later would miss the presence of power resource support, and the rest of the code will keep using Optimus DSM, breaking power management for that machine. Also, because we're detecting NVIDIA's DSM, it doesn't make sense to run this detection on a non-NVIDIA device anyway. Thus, check at the beginning of the detection code if this is an NVIDIA card, and just return if it isn't. This, together with commit d22915d22ded ("drm/nouveau/devinit/tu102-: wait for GFW_BOOT_PROGRESS == COMPLETED") developed independently and landed earlier, fixes runtime power management of the NVIDIA card in Lenovo Legion 5-15ARH05. Without this patch, the GPU resumption code will "timeout", sometimes hanging userspace. As a bonus, we'll also stop preventing _PR3 usage from the bridge for unrelated devices, which is always nice, I guess.

2023-06-13usb: gadget: udc: core: Prevent soft_connect_store() raceBadhri Jagan Sridharan
usb_udc_connect_control(), soft_connect_store() and usb_gadget_deactivate() can potentially race against each other to invoke usb_gadget_connect()/usb_gadget_disconnect(). To prevent this, guard udc->started, gadget->allow_connect, gadget->deactivate and gadget->connect with connect_lock so that ->pullup() is only invoked when the gadget is bound, started and not deactivated. The routines usb_gadget_connect_locked(), usb_gadget_disconnect_locked(), usb_udc_connect_control_locked(), usb_gadget_udc_start_locked(), usb_gadget_udc_stop_locked() are called with this lock held. An earlier version of this commit was reverted due to the crash reported in https://lore.kernel.org/all/ZF4BvgsOyoKxdPFF@francesco-nb.int.toradex.com/. commit 16737e78d190 ("usb: gadget: udc: core: Offload usb_udc_vbus_handler processing") addresses the crash reported.

2023-06-13usb: gadget: udc: core: Offload usb_udc_vbus_handler processingBadhri Jagan Sridharan
usb_udc_vbus_handler() can be invoked from interrupt context by irq handlers of the gadget drivers, however, usb_udc_connect_control() has to run in non-atomic context due to the following: a. Some of the gadget driver implementations expect the ->pullup callback to be invoked in non-atomic context. b. usb_gadget_disconnect() acquires udc_lock which is a mutex. Hence offload invocation of usb_udc_connect_control() to workqueue. UDC should not be pulled up unless gadget driver is bound. The new flag "allow_connect" is now set by gadget_bind_driver() and cleared by gadget_unbind_driver(). This prevents work item to pull up the gadget even if queued when the gadget driver is already unbound.

Some dwc3 glue drivers are currently accessing the driver data of the child core device directly, which is clearly a bad idea as the child may not have probed yet or may have been unbound from its driver. As a workaround until the glue drivers have been fixed, clear the driver data pointer before allowing the glue parent device to runtime suspend to prevent its driver from accessing data that has been freed during unbind.

2023-06-13USB: dwc3: qcom: fix NULL-deref on suspendJohan Hovold
The Qualcomm dwc3 glue driver is currently accessing the driver data of the child core device during suspend and on wakeup interrupts. This is clearly a bad idea as the child may not have probed yet or could have been unbound from its driver. The first such layering violation was part of the initial version of the driver, but this was later made worse when the hack that accesses the driver data of the grand child xhci device to configure the wakeup interrupts was added. Fixing this properly is not that easily done, so add a sanity check to make sure that the child driver data is non-NULL before dereferencing it for now. Note that this relies on subtleties like the fact that driver core is making sure that the parent is not suspended while the child is probing.

2023-06-13usb: dwc3: gadget: Reset num TRBs before giving back the requestElson Roy Serrao
Consider a scenario where cable disconnect happens when there is an active usb reqest queued to the UDC. As part of the disconnect we would issue an end transfer with no interrupt-on-completion before giving back this request. Since we are giving back the request without skipping TRBs the num_trbs field of dwc3_request still holds the stale value previously used. Function drivers re-use same request for a given bind-unbind session and hence their dwc3_request context gets preserved across cable disconnect/connect. When such a request gets re-queued after cable connect, we would increase the num_trbs field on top of the previous stale value thus incorrectly representing the number of TRBs used. Fix this by resetting num_trbs field before giving back the request.
