2024-03-07PCI/AER: Block runtime suspend when handling errorsStanislaw Gruszka
PM runtime can be done simultaneously with AER error handling. Avoid that by using pm_runtime_get_sync() before and pm_runtime_put() after reset in pcie_do_recovery() for all recovering devices. pm_runtime_get_sync() will increase dev->power.usage_count counter to prevent any possible future request to runtime suspend a device. It will also resume a device, if it was previously in D3hot state. I tested with igc device by doing simultaneous aer_inject and rpm suspend/resume via /sys/bus/pci/devices/PCI_ID/power/control and can reproduce: igc 0000:02:00.0: not ready 65535ms after bus reset; giving up pcieport 0000:00:1c.2: AER: Root Port link has been reset (-25) pcieport 0000:00:1c.2: AER: subordinate device reset failed pcieport 0000:00:1c.2: AER: device recovery failed igc 0000:02:00.0: Unable to change power state from D3hot to D0, device inaccessible The problem disappears when this patch is applied.

2024-03-07Input: synaptics-rmi4 - fix UAF of IRQ domain on driver removalMathias Krause
Calling irq_domain_remove() will lead to freeing the IRQ domain prematurely. The domain is still referenced and will be attempted to get used via rmi_free_function_list() -> rmi_unregister_function() -> irq_dispose_mapping() -> irq_get_irq_data()'s ->domain pointer. With PaX's MEMORY_SANITIZE this will lead to an access fault when attempting to dereference embedded pointers, as in Torsten's report that was faulting on the 'domain->ops->unmap' test. Fix this by releasing the IRQ domain only after all related IRQs have been deactivated.

2024-03-07driver core: Add FWLINK_FLAG_IGNORE to completely ignore a fwnode linkSaravana Kannan
A fwnode link between specific supplier-consumer fwnodes can be added multiple times for multiple reasons. If that dependency doesn't exist, deleting the fwnode link once doesn't guarantee that it won't get created again. So, add FWLINK_FLAG_IGNORE flag to mark a fwnode link as one that needs to be completely ignored. Since a fwnode link's flags is an OR of all the flags passed to all the fwnode_link_add() calls to create that specific fwnode link, the FWLINK_FLAG_IGNORE flag is preserved and can be used to mark a fwnode link as on that need to be completely ignored until it is deleted.

2024-03-07cnic,bnx2,bnx2x: use UIO_MEM_DMA_COHERENTChris Leech
Use the UIO_MEM_DMA_COHERENT type to properly handle mmap for dma_alloc_coherent buffers. The cnic l2_ring and l2_buf mmaps have caused page refcount issues as the dma_alloc_coherent no longer provide __GFP_COMP allocation as per commit "dma-mapping: reject __GFP_COMP in dma_alloc_attrs". Fix this by having the uio device use dma_mmap_coherent. The bnx2 and bnx2x status block allocations are also dma_alloc_coherent, and should use dma_mmap_coherent. They don't allocate multiple pages, but this interface does not work correctly with an iommu enabled unless dma_mmap_coherent is used.

2024-03-07cdx: add MSI support for CDX busNipun Gupta
Add CDX-MSI domain per CDX controller with gic-its domain as a parent, to support MSI for CDX devices. CDX devices allocate MSIs from the CDX domain. Also, introduce APIs to alloc and free IRQs for CDX domain. In CDX subsystem firmware is a controller for all devices and their configuration. CDX bus controller sends all the write_msi_msg commands to firmware running on RPU and the firmware interfaces with actual devices to pass this information to devices Since, CDX controller is the only way to communicate with the Firmware for MSI write info, CDX domain per controller required in contrast to having a CDX domain per device.

When userland echoes 8bit characters to /dev/synth with e.g. echo -e '\xe9' > /dev/synth synth_write would get characters beyond 0x7f, and thus negative when char is signed. When given to synth_buffer_add which takes a u16, this would sign-extend and produce a U+ffxy character rather than U+xy. Users thus get garbled text instead of accents in their output. Let's fix this by making sure that we read unsigned characters.

2024-03-07platform: goldfish: move the separate 'default' propery for CONFIG_GOLDFISHMasahiro Yamada
Currently, there are two entries for CONFIG_GOLDFISH. In arch/x86/Kconfig: config GOLDFISH def_bool y depends on X86_GOLDFISH In drivers/platform/goldfish/Kconfig: menuconfig GOLDFISH bool "Platform support for Goldfish virtual devices" depends on HAS_IOMEM && HAS_DMA While Kconfig allows multiple entries, it generally leads to tricky code. Prior to commit bd2f348db503 ("goldfish: refactor goldfish platform configs"), CONFIG_GOLDFISH was an alias of CONFIG_X86_GOLDFISH. After the mentioned commit added the second entry with a user prompt, the former provides the 'default' property that is effective only when X86_GOLDFISH=y. Merge them tegether to clarify how it has worked in the past 8 years.

2024-03-07greybus: Remove usage of the deprecated ida_simple_xx() APIChristophe JAILLET
ida_alloc() and ida_free() should be preferred to the deprecated ida_simple_get() and ida_simple_remove(). Note that the upper limit of ida_simple_get() is exclusive, but the one of ida_alloc_range()/ida_alloc_max() is inclusive. So a -1 has been added when needed.

2024-03-07usb: gadget: tegra-xudc: Fix USB3 PHY retrieval logicWayne Chang
This commit resolves an issue in the tegra-xudc USB gadget driver that incorrectly fetched USB3 PHY instances. The problem stemmed from the assumption of a one-to-one correspondence between USB2 and USB3 PHY names and their association with physical USB ports in the device tree. Previously, the driver associated USB3 PHY names directly with the USB3 instance number, leading to mismatches when mapping the physical USB ports. For instance, if using USB3-1 PHY, the driver expect the corresponding PHY name as 'usb3-1'. However, the physical USB ports in the device tree were designated as USB2-0 and USB3-0 as we only have one device controller, causing a misalignment. This commit rectifies the issue by adjusting the PHY naming logic. Now, the driver correctly correlates the USB2 and USB3 PHY instances, allowing the USB2-0 and USB3-1 PHYs to form a physical USB port pair while accurately reflecting their configuration in the device tree by naming them USB2-0 and USB3-0, respectively. The change ensures that the PHY and PHY names align appropriately, resolving the mismatch between physical USB ports and their associated names in the device tree.

This patch introduces a new API, tegra_xusb_padctl_get_port_number, to the Tegra XUSB Pad Controller driver. This API is used to identify the USB port that is associated with a given PHY. The function takes a PHY pointer for either a USB2 PHY or USB3 PHY as input and returns the corresponding port number. If the PHY pointer is invalid, it returns -ENODEV.
