HID: logitech-hidpp: Prevent use-after-free on force feedback initialisation failure
Presently, if the force feedback initialisation fails when probing the Logitech G920 Driving Force Racing Wheel for Xbox One, an error number will be returned and propagated before the userspace infrastructure (sysfs and /dev/input) has been torn down. If userspace ignores the errors and continues to use its references to these dangling entities, a UAF will promptly follow. We have 2 options; continue to return the error, but ensure that all of the infrastructure is torn down accordingly or continue to treat this condition as a warning by emitting the message but returning success. It is thought that the original author's intention was to emit the warning but keep the device functional, less the force feedback feature, so let's go with that.

HID: bpf: prevent buffer overflow in hid_hw_request
right now the returned value is considered to be always valid. However,
when playing with HID-BPF, the return value can be arbitrary big,
because it's the return value of dispatch_hid_bpf_raw_requests(), which
calls the struct_ops and we have no guarantees that the value makes
sense.

selftests/hid: fix compilation when bpf_wq and hid_device are not exported
This can happen in situations when CONFIG_HID_SUPPORT is set to no, or
some complex situations where struct bpf_wq is not exported.
So do the usual dance of hiding them before including vmlinux.h, and
then redefining them and make use of CO-RE to have the correct offsets.

HID: core: Mitigate potential OOB by removing bogus memset()
The memset() in hid_report_raw_event() has the good intention of clearing out bogus data by zeroing the area from the end of the incoming data string to the assumed end of the buffer. However, as we have previously seen, doing so can easily result in OOB reads and writes in the subsequent thread of execution. The current suggestion from one of the HID maintainers is to remove the memset() and simply return if the incoming event buffer size is not large enough to fill the associated report.

HID: intel-thc-hid: Set HID_PHYS with PCI BDF
Currently HID_PHYS is empty, which means userspace tools (e.g. fwupd) that depend on it for distinguishing the devices, are unable to do so. Other drivers like i2c-hid, usbhid, surface-hid, all populate it. With this change it's set to, for example: HID_PHYS=0000:00:10.0 Each function has just a single HID device, as far as I can tell, so there is no need to add a suffix.

HID: input: Add HID_BATTERY_QUIRK_DYNAMIC for Elan touchscreens
Elan touchscreens have a HID-battery device for the stylus which is always there even if there is no stylus. This is causing upower to report an empty battery for the stylus and some desktop-environments will show a notification about this, which is quite annoying. Because of this the HID-battery is being ignored on all Elan I2c and USB touchscreens, but this causes there to be no battery reporting for the stylus at all. This adds a new HID_BATTERY_QUIRK_DYNAMIC and uses these for the Elan touchscreens. This new quirks causes the present value of the battery to start at 0, which will make userspace ignore it and only sets present to 1 after receiving a battery input report which only happens when the stylus gets in range.

HID: wacom: fix out-of-bounds read in wacom_intuos_bt_irq
The wacom_intuos_bt_irq() function processes Bluetooth HID reports without sufficient bounds checking. A maliciously crafted short report can trigger an out-of-bounds read when copying data into the wacom structure. Specifically, report 0x03 requires at least 22 bytes to safely read the processed data and battery status, while report 0x04 (which falls through to 0x03) requires 32 bytes. Add explicit length checks for these report IDs and log a warning if a short report is received.

HID: Document memory allocation properties of report_fixup()
The memory pointer returned by the report_fixup() hook does not get freed by the caller. Instead, report_fixup() must return (in return value and *rsize) a memory buffer with at least the same lifetime as the input buffer (defined by rdesc and original *rsize). This is usually achieved using one of the following techniques: * Returning a pointer and size to a sub-portion of the input buffer * Returning a pointer to a static buffer * Allocating a buffer with a devm_*() function, which will automatically get freed when the device is removed.

* MTD
The ofpart parsing in physmap-core has been prioritized.
There has been a series of conversion to scoped for each OF child
loops.
* Bindings
The bulk of the changes consists in binding fixes/updates to restrict
the use of undefined properties, which was almost inefficient in the
current form because of the nesting of partition nodes and the lack of
compatible strings sometimes.
These changes are accompanied by YAML conversions and the addition of a
dma-coherent property in the cdns,hp-nfc driver.
* SPI NAND
The major feature this release is the support for octal DTR
modes (8D-8D-8D).
Support for Foresee F35SQB002G chips has been added.
Other changes are small misc fixes.

Loongarch:
- Add more CPUCFG mask bits. - Improve feature detection. - Add lazy load support for FPU and binary translation (LBT) register state. - Fix return value for memory reads from and writes to in-kernel devices. - Add support for detecting preemption from within a guest. - Add KVM steal time test case to tools/selftests. ARM: - Add support for FEAT_IDST, allowing ID registers that are not implemented to be reported as a normal trap rather than as an UNDEF exception. - Add sanitisation of the VTCR_EL2 register, fixing a number of UXN/PXN/XN bugs in the process. - Full handling of RESx bits, instead of only RES0, and resulting in SCTLR_EL2 being added to the list of sanitised registers. - More pKVM fixes for features that are not supposed to be exposed to guests. - Make sure that MTE being disabled on the pKVM host doesn't give it the ability to attack the hypervisor. - Allow pKVM's host stage-2 mappings to use the Force Write Back version of the memory attributes by using the "pass-through' encoding. - Fix trapping of ICC_DIR_EL1 on GICv5 hosts emulating GICv3 for the guest. - Preliminary work for guest GICv5 support. - A bunch of debugfs fixes, removing pointless custom iterators stored in guest data structures. - A small set of FPSIMD cleanups. - Selftest fixes addressing the incorrect alignment of page allocation. - Other assorted low-impact fixes and spelling fixes. RISC-V: - Fixes for issues discoverd by KVM API fuzzing in kvm_riscv_aia_imsic_has_attr(), kvm_riscv_aia_imsic_rw_attr(), and kvm_riscv_vcpu_aia_imsic_update() - Allow Zalasr, Zilsd and Zclsd extensions for Guest/VM - Transparent huge page support for hypervisor page tables - Adjust the number of available guest irq files based on MMIO register sizes found in the device tree or the ACPI tables - Add RISC-V specific paging modes to KVM selftests - Detect paging mode at runtime for selftests s390: - Performance improvement for vSIE (aka nested virtualization) - Completely new memory management. s390 was a special snowflake that enlisted help from the architecture's page table management to build hypervisor page tables, in particular enabling sharing the last level of page tables. This however was a lot of code (~3K lines) in order to support KVM, and also blocked several features. The biggest advantages is that the page size of userspace is completely independent of the page size used by the guest: userspace can mix normal pages, THPs and hugetlbfs as it sees fit, and in fact transparent hugepages were not possible before. It's also now possible to have nested guests and guests with huge pages running on the same host. - Maintainership change for s390 vfio-pci - Small quality of life improvement for protected guests x86: - Add support for giving the guest full ownership of PMU hardware (contexted switched around the fastpath run loop) and allowing direct access to data MSRs and PMCs (restricted by the vPMU model). KVM still intercepts access to control registers, e.g. to enforce event filtering and to prevent the guest from profiling sensitive host state. This is more accurate, since it has no risk of contention and thus dropped events, and also has significantly less overhead. For more information, see the commit message for merge commit |

ARM: clean up the memset64() C wrapper
The current logic to split the 64-bit argument into its 32-bit halves is byte-order specific and a bit clunky. Use a union instead which is easier to read and works in all cases. GCC still generates the same machine code. While at it, rename the arguments of the __memset64() prototype to actually reflect their semantics.

commands (Niklas).
- Improve the handling of Thunderbolt attached devices to speed up
device removal (Henry).
- Several patches to generalize the existing max_sec quirks to
facilitates quirking the maximum command size of buggy drives, many
of which have recently showed up with the recent increase of the
default max_sectors block limit (Niklas).
- Cleanup the ahci-platform and sata dt-bindings schema (Rob,
Manivannan).
- Improve device node scan in the ahci-dwc driver (Krzysztof).
- Remove clang W=1 warnings with the ahci-imx and ahci-xgene drivers
(Krzysztof).
- Fix a long standing potential command starvation situation with
non-NCQ commands issued when NCQ commands are on-going (me).
- Limit max_sectors to 8191 on the INTEL SSDSC2KG480G8 SSD (Niklas).
- Remove Vesa Local Bus (VLB) support in the pata_legacy driver
(Ethan).
- Simple fixes in the pata_cypress (typo) and pata_ftide010 (timing)
drivers (Ethan, Linus W.)

cxl changes for v7.0
- A set of commits that introduces cxl_memdev_attach and pave way for soft reserved handling, type2 accelerator enabling, and LSA 2.0 enabling. All these series require the endpoint driver to settle before continuing the memdev driver probe. dax/hmem, e820, resource: Defer Soft Reserved insertion until hmem is ready cxl/mem: Introduce cxl_memdev_attach for CXL-dependent operation cxl/mem: Drop @host argument to devm_cxl_add_memdev() cxl/mem: Convert devm_cxl_add_memdev() to scope-based-cleanup cxl/port: Arrange for always synchronous endpoint attach cxl/mem: Arrange for always-synchronous memdev attach cxl/mem: Fix devm_cxl_memdev_edac_release() confusion - A set to address CXL port error protocol handling and reporting. The large patch series was split into 3 parts. Part 1 and 2 are included here with part 3 coming later. Part 1 consists of a series of code refactoring to PCI AER sub-system that addresses CXL and also CXL RAS code to prepare for port error handling. Part 2 refactors the CXL code to move management of component registers to cxl_port objects to allow all CXL AER errors to be handled through the cxl_port hierarchy.

procfs: fix possible double mmput() in do_procmap_query()
When user provides incorrectly sized buffer for build ID for PROCMAP_QUERY
we return with -ENAMETOOLONG error. After recent changes this condition
happens later, after we unlocked mmap_lock/per-VMA lock and did mmput(),
so original goto out is now wrong and will double-mmput() mm_struct. Fix
by jumping further to clean up only vm_file and name_buf.

RTLA patches for v7.0
- Remove unused function declarations Some functions were removed in recent code consolidation 6.18, but their prototypes were not removed from headers. Remove them. - Set stop threshold after enabling instances Prefer recording samples without stopping on them on the start of tracing to stopping on samples that are never recorded. This fixes flakiness of some RTLA tests and unifies behavior of sample collection between tracefs mode and BPF mode. - Consolidate usage help message implementation RTLA tools (osnoise-top, osnoise-hist, timerlat-top, timerlat-hist) each implement usage help individually. Move common logic between them into a new function to reduce code duplication. - Add BPF actions feature Add option --bpf-action to attach a BPF program (passed as filename of its ELF representation) to be executed via BPF tail call at latency threshold. - Consolidate command line option parsing Each RTLA tool implements the parsing of command line options individually. Now that we have a common structure for parameters, unify the parsing of those options common among all four tools into one function. - De-duplicate cgroup common code Two functions in utils.c, setting cgroup for comm and setting cgroup for pid, duplicate code for constructing the cgroup path. Extract it to a new helper function. - String and error handling fixes and cleanups There were several instances of unsafe string and error handling that could cause invalid memory access; fix them. Also, remove a few unused headers, update .gitignore, and deduplicate code. -----BEGIN PGP SIGNATURE----- iIoEABYKADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCaY3l2RQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qrWcAP4lsfIbNhfvmc9htDON/GlCu9FK8PTT hmAsO7MeHh29OwD+OS7RZzRza+3G+B4aTcqUXQVfAvx9qenS591LcktQSAo= =VUW2 -----END PGP SIGNATURE----- Merge tag 'trace-rtla-v7.0' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull RTLA updates from Steven Rostedt: - Remove unused function declarations Some functions were removed in recent code consolidation 6.18, but their prototypes were not removed from headers.
