      MR: https://gitlab.com/redhat/centos-stream/src/kernel/centos-stream-10/-/merge_requests/648

```
    PCI updates from upstream v6.14:
     "Enumeration:

       - Make pci_stop_dev() and pci_destroy_dev() safe so concurrent
         callers can't stop a device multiple times, even as we migrate from
         the global pci_rescan_remove_lock to finer-grained locking (Keith
         Busch)

       - Improve pci_walk_bus() implementation by making it recursive and
         moving locking up to avoid need for a 'locked' parameter (Keith
         Busch)

       - Unexport pci_walk_bus_locked(), which is only used internally by
         the PCI core (Keith Busch)

       - Detect some Thunderbolt chips that are built-in and hence
         'trustworthy' by a heuristic since the 'ExternalFacingPort' and
         'usb4-host-interface' ACPI properties are not quite enough (Esther
         Shimanovich)

      Resource management:

       - Use PCI bus addresses (not CPU addresses) in 'ranges' properties
         when building dynamic DT nodes so systems where PCI and CPU
         addresses differ work correctly (Andrea della Porta)

       - Tidy resource sizing and assignment with helpers to reduce
         redundancy (Ilpo Järvinen)

       - Improve pdev_sort_resources() 'bogus alignment' warning to be more
         specific (Ilpo Järvinen)

      Driver binding:

       - Convert driver .remove_new() callbacks to .remove() again to finish
         the conversion from returning 'int' to being 'void' (Sergio
         Paracuellos)

       - Export pcim_request_all_regions(), a managed interface to request
         all BARs (Philipp Stanner)

       - Replace pcim_iomap_regions_request_all() with
         pcim_request_all_regions(), and pcim_iomap_table()[n] with
         pcim_iomap(n), in the following drivers: ahci, crypto qat, crypto
         octeontx2, intel_th, iwlwifi, ntb idt, serial rp2, ALSA korg1212
         (Philipp Stanner)

       - Remove the now unused pcim_iomap_regions_request_all() (Philipp
         Stanner)

       - Export pcim_iounmap_region(), a managed interface to unmap and
         release a PCI BAR (Philipp Stanner)

       - Replace pcim_iomap_regions(mask) with pcim_iomap_region(n), and
         pcim_iounmap_regions(mask) with pcim_iounmap_region(n), in the
         following drivers: fpga dfl-pci, block mtip32xx, gpio-merrifield,
         cavium (Philipp Stanner)

      Error handling:

       - Add sysfs 'reset_subordinate' to reset the entire hierarchy below a
         bridge; previously Secondary Bus Reset could only be used when
         there was a single device below a bridge (Keith Busch)

       - Warn if we reset a running device where the driver didn't register
         pci_error_handlers notification callbacks (Keith Busch)

      ASPM:

       - Disable ASPM L1 before touching L1 PM Substates to follow the spec
         closer and avoid a CPU load timeout on some platforms (Ajay
         Agarwal)

       - Set devices below Intel VMD to D0 before enabling ASPM L1 Substates
         as required per spec for all L1 Substates changes (Jian-Hong Pan)

      Power management:

       - Enable starfive controller runtime PM before probing host bridge
         (Mayank Rana)

       - Enable runtime power management for host bridges (Krishna chaitanya
         chundru)

      Power control:

       - Use of_platform_device_create() instead of of_platform_populate()
         to create pwrctl platform devices so we can control it based on the
         child nodes (Manivannan Sadhasivam)

       - Create pwrctrl platform devices only if there's a relevant power
         supply property (Manivannan Sadhasivam)

       - Add device link from the pwrctl supplier to the PCI dev to ensure
         pwrctl drivers are probed before the PCI dev driver; this avoids a
         race where pwrctl could change device power state while the PCI
         driver was active (Manivannan Sadhasivam)

       - Find pwrctl device for removal with of_find_device_by_node()
         instead of searching all children of the parent (Manivannan
         Sadhasivam)

       - Rename 'pwrctl' to 'pwrctrl' to match new bandwidth controller
         ('bwctrl') and hotplug files (Bjorn Helgaas)

      Bandwidth control:

       - Add read/modify/write locking for Link Control 2, which is used to
         manage Link speed (Ilpo Järvinen)

       - Extract Link Bandwidth Management Status check into
         pcie_lbms_seen(), where it can be shared between the bandwidth
         controller and quirks that use it to help retrain failed links
         (Ilpo Järvinen)

       - Re-add Link Bandwidth notification support with updates to address
         the reasons it was previously reverted (Alexandru Gagniuc, Ilpo
         Järvinen)

       - Add pcie_set_target_speed() and related functionality so drivers
         can manage PCIe Link speed based on thermal or other constraints
         (Ilpo Järvinen)

       - Add a thermal cooling driver to throttle PCIe Links via the
         existing thermal management framework (Ilpo Järvinen)

       - Add a userspace selftest for the PCIe bandwidth controller (Ilpo
         Järvinen)

      PCI device hotplug:

       - Add hotplug controller driver for Marvell OCTEON multi-function
         device where function 0 has a management console interface to
         enable/disable and provision various personalities for the other
         functions (Shijith Thotton)

       - Retain a reference to the pci_bus for the lifetime of a pci_slot to
         avoid a use-after-free when the thunderbolt driver resets USB4 host
         routers on boot, causing hotplug remove/add of downstream docks or
         other devices (Lukas Wunner)

       - Remove unused cpcihp struct cpci_hp_controller_ops.hardware_test
         (Guilherme Giacomo Simoes)

       - Remove unused cpqphp struct ctrl_dbg.ctrl (Christophe JAILLET)

       - Use pci_bus_read_dev_vendor_id() instead of hand-coded presence
         detection in cpqphp (Ilpo Järvinen)

       - Simplify cpqphp enumeration, which is already simple-minded and
         doesn't handle devices below hot-added bridges (Ilpo Järvinen)

      Virtualization:

       - Add ACS quirk for Wangxun FF5xxx NICs, which don't advertise an ACS
         capability but do isolate functions as though PCI_ACS_RR and
         PCI_ACS_CR were set, so the functions can be in independent IOMMU
         groups (Mengyuan Lou)

      TLP Processing Hints (TPH):

       - Add and document TLP Processing Hints (TPH) support so drivers can
         enable and disable TPH and the kernel can save/restore TPH
         configuration (Wei Huang)

       - Add TPH Steering Tag support so drivers can retrieve Steering Tag
         values associated with specific CPUs via an ACPI _DSM to improve
         performance by directing DMA writes closer to their consumers (Wei
         Huang)

      Data Object Exchange (DOE):

       - Wait up to 1 second for DOE Busy bit to clear before writing a
         request to the mailbox to avoid failures if the mailbox is still
         busy from a previous transfer (Gregory Price)

      Endpoint framework:

       - Skip attempts to allocate from endpoint controller memory window if
         the requested size is larger than the window (Damien Le Moal)

       - Add and document pci_epc_mem_map() and pci_epc_mem_unmap() to
         handle controller-specific size and alignment constraints, and add
         test cases to the endpoint test driver (Damien Le Moal)

       - Implement dwc pci_epc_ops.align_addr() so pci_epc_mem_map() can
         observe DWC-specific alignment requirements (Damien Le Moal)

       - Synchronously cancel command handler work in endpoint test before
         cleaning up DMA and BARs (Damien Le Moal)

       - Respect endpoint page size in dw_pcie_ep_align_addr() (Niklas
         Cassel)

       - Use dw_pcie_ep_align_addr() in dw_pcie_ep_raise_msi_irq() and
         dw_pcie_ep_raise_msix_irq() instead of open coding the equivalent
         (Niklas Cassel)

       - Avoid NULL dereference if Modem Host Interface Endpoint lacks
         'mmio' DT property (Zhongqiu Han)

       - Release PCI domain ID of Endpoint controller parent (not controller
         itself) and before unregistering the controller, to avoid
         use-after-free (Zijun Hu)

       - Clear secondary (not primary) EPC in pci_epc_remove_epf() when
         removing the secondary controller associated with an NTB (Zijun Hu)

      Cadence PCIe controller driver:

       - Lower severity of 'phy-names' message (Bartosz Wawrzyniak)

      Freescale i.MX6 PCIe controller driver:

       - Fix suspend/resume support on i.MX6QDL, which has a hardware
         erratum that prevents use of L2 (Stefan Eichenberger)

      Intel VMD host bridge driver:

       - Add 0xb60b and 0xb06f Device IDs for client SKUs (Nirmal Patel)

      MediaTek PCIe Gen3 controller driver:

       - Update mediatek-gen3 DT binding to require the exact number of
         clocks for each SoC (Fei Shao)

       - Add support for DT 'max-link-speed' and 'num-lanes' properties to
         restrict the link speed and width (AngeloGioacchino Del Regno)

      Microchip PolarFlare PCIe controller driver:

       - Add DT and driver support for using either of the two PolarFire
         Root Ports (Conor Dooley)

      NVIDIA Tegra194 PCIe controller driver:

       - Move endpoint controller cleanups that depend on refclk from the
         host to the notifier that tells us the host has deasserted PERST#,
         when refclk should be valid (Manivannan Sadhasivam)

      Qualcomm PCIe controller driver:

       - Add qcom SAR2130P DT binding with an additional clock (Dmitry
         Baryshkov)

       - Enable MSI interrupts if 'global' IRQ is supported, since a
         previous commit unintentionally masked them (Manivannan Sadhasivam)

       - Move endpoint controller cleanups that depend on refclk from the
         host to the notifier that tells us the host has deasserted PERST#,
         when refclk should be valid (Manivannan Sadhasivam)

       - Add DT binding and driver support for IPQ9574, with Synopsys IP
         v5.80a and Qcom IP 1.27.0 (devi priya)

       - Move the OPP "operating-points-v2" table from the
         qcom,pcie-sm8450.yaml DT binding to qcom,pcie-common.yaml, where it
         can be used by other Qcom platforms (Qiang Yu)

       - Add 'global' SPI interrupt for events like link-up, link-down to
         qcom,pcie-x1e80100 DT binding so we can start enumeration when the
         link comes up (Qiang Yu)

       - Disable ASPM L0s for qcom,pcie-x1e80100 since the PHY is not tuned
         to support this (Qiang Yu)

       - Add ops_1_21_0 for SC8280X family SoC, which doesn't use the
         'iommu-map' DT property and doesn't need BDF-to-SID translation
         (Qiang Yu)

      Rockchip PCIe controller driver:

       - Define ROCKCHIP_PCIE_AT_SIZE_ALIGN to replace magic 256 endpoint
         .align value (Damien Le Moal)

       - When unmapping an endpoint window, compute the region index instead
         of searching for it, and verify that the address was mapped (Damien
         Le Moal)

       - When mapping an endpoint window, verify that the address hasn't
         been mapped already (Damien Le Moal)

       - Implement pci_epc_ops.align_addr() for rockchip-ep (Damien Le Moal)

       - Fix MSI IRQ data mapping to observe the alignment constraint, which
         fixes intermittent page faults in memcpy_toio() and memcpy_fromio()
         (Damien Le Moal)

       - Rename rockchip_pcie_parse_ep_dt() to
         rockchip_pcie_ep_get_resources() for consistency with similar DT
         interfaces (Damien Le Moal)

       - Skip the unnecessary link train in rockchip_pcie_ep_probe() and do
         it only in the endpoint start operation (Damien Le Moal)

       - Implement pci_epc_ops.stop_link() to disable link training and
         controller configuration (Damien Le Moal)

       - Attempt link training at 5 GT/s when both partners support it
         (Damien Le Moal)

       - Add a handler for PERST# signal so we can detect host-initiated
         resets and start link training after PERST# is deasserted (Damien
         Le Moal)

      Synopsys DesignWare PCIe controller driver:

       - Clear outbound address on unmap so dw_pcie_find_index() won't match
         an ATU index that was already unmapped (Damien Le Moal)

       - Use of_property_present() instead of of_property_read_bool() when
         testing for presence of non-boolean DT properties (Rob Herring)

       - Advertise 1MB size if endpoint supports Resizable BARs, which was
         inadvertently lost in v6.11 (Niklas Cassel)

      TI J721E PCIe driver:

       - Add PCIe support for J722S SoC (Siddharth Vadapalli)

       - Delay PCIE_T_PVPERL_MS (100 ms), not just PCIE_T_PERST_CLK_US (100
         us), before deasserting PERST# to ensure power and refclk are
         stable (Siddharth Vadapalli)

      TI Keystone PCIe controller driver:

       - Set the 'ti,keystone-pcie' mode so v3.65a devices work in Root
         Complex mode (Kishon Vijay Abraham I)

       - Try to avoid unrecoverable SError for attempts to issue config
         transactions when the link is down; this is racy but the best we
         can do (Kishon Vijay Abraham I)

      Miscellaneous:

       - Reorganize kerneldoc parameter names to match order in function
         signature (Julia Lawall)

CVE: CVE-2025-21857

```
commit 071ed42cff4fcdd89025d966d48eabef59913bf2
Author: Pierre Riteau <pierre@stackhpc.com>
Date:   Thu Feb 13 23:36:10 2025 +0100

    net/sched: cls_api: fix error handling causing NULL dereference

    tcf_exts_miss_cookie_base_alloc() calls xa_alloc_cyclic() which can
    return 1 if the allocation succeeded after wrapping. This was treated as
    an error, with value 1 returned to caller tcf_exts_init_ex() which sets
    exts->actions to NULL and returns 1 to caller fl_change().

    fl_change() treats err == 1 as success, calling tcf_exts_validate_ex()
    which calls tcf_action_init() with exts->actions as argument, where it
    is dereferenced.

    Example trace:

    BUG: kernel NULL pointer dereference, address: 0000000000000000
