2024-09-12mmc: dw_mmc: Fix IDMAC operation with pages bigger than 4KSam Protsenko1-2/+2
commit 8396c793ffdf28bb8aee7cfe0891080f8cab7890 upstream. Commit 616f87661792 ("mmc: pass queue_limits to blk_mq_alloc_disk") [1] revealed the long living issue in dw_mmc.c driver, existing since the time when it was first introduced in commit f95f3850f7a9 ("mmc: dw_mmc: Add Synopsys DesignWare mmc host driver."), also making kernel boot broken on platforms using dw_mmc driver with 16K or 64K pages enabled, with this message in dmesg: mmcblk: probe of mmc0:0001 failed with error -22 That's happening because mmc_blk_probe() fails when it calls blk_validate_limits() consequently, which returns the error due to failed max_segment_size check in this code: /* * The maximum segment size has an odd historic 64k default that * drivers probably should override. Just like the I/O size we * require drivers to at least handle a full page per segment. */ ... if (WARN_ON_ONCE(lim->max_segment_size < PAGE_SIZE)) return -EINVAL; In case when IDMAC (Internal DMA Controller) is used, dw_mmc.c always sets .max_seg_size to 4 KiB: mmc->max_seg_size = 0x1000; The comment in the code above explains why it's incorrect. Arnd suggested setting .max_seg_size to .max_req_size to fix it, which is also what some other drivers are doing: $ grep -rl 'max_seg_size.*=.*max_req_size' drivers/mmc/host/ | \ wc -l 18 This change is not only fixing the boot with 16K/64K pages, but also leads to a better MMC performance. The linear write performance was tested on E850-96 board (eMMC only), before commit [1] (where it's possible to boot with 16K/64K pages without this fix, to be able to do a comparison). It was tested with this command: # dd if=/dev/zero of=somefile bs=1M count=500 oflag=sync Test results are as follows: - 4K pages, .max_seg_size = 4 KiB: 94.2 MB/s - 4K pages, .max_seg_size = .max_req_size = 512 KiB: 96.9 MB/s - 16K pages, .max_seg_size = 4 KiB: 126 MB/s - 16K pages, .max_seg_size = .max_req_size = 2 MiB: 128 MB/s - 64K pages, .max_seg_size = 4 KiB: 138 MB/s - 64K pages, .max_seg_size = .max_req_size = 8 MiB: 138 MB/s Unfortunately, SD card controller is not enabled in E850-96 yet, so it wasn't possible for me to run the test on some cheap SD cards to check this patch's impact on those. But it's possible that this change might also reduce the writes count, thus improving SD/eMMC longevity. All credit for the analysis and the suggested solution goes to Arnd.

commit c5af2c90ba5629f0424a8d315f75fb8d91713c3c upstream. gicv2m_of_init() fails to perform an of_node_put() when of_address_to_resource() fails, leading to a refcount leak.

commit 284b75a3d83c7631586d98f6dede1d90f128f0db upstream. In ata_host_alloc(), if devres_alloc() fails to allocate the device host resource data pointer, the already allocated ata_host structure is not freed before returning from the function. This results in a potential memory leak. Call kfree(host) before jumping to the error handling path to ensure that the ata_host structure is properly freed if devres_alloc() fails.

2024-09-12media: uvcvideo: Enforce alignment of frame and intervalRicardo Ribalda1-4/+14
[ Upstream commit c8931ef55bd325052ec496f242aea7f6de47dc9c ] Struct uvc_frame and interval (u32*) are packaged together on streaming->formats on a single contiguous allocation. Right now they are allocated right after uvc_format, without taking into consideration their required alignment. This is working fine because both structures have a field with a pointer, but it will stop working when the sizeof() of any of those structs is not a multiple of the sizeof(void*). Enforce that alignment during the allocation.

2024-09-12usbip: Don't submit special requests twiceSimon Holesch1-27/+50
[ Upstream commit 8b6b386f9aa936ed0c190446c71cf59d4a507690 ] Skip submitting URBs, when identical requests were already sent in tweak_special_requests(). Instead call the completion handler directly to return the result of the URB. Even though submitting those requests twice should be harmless, there are USB devices that react poorly to some duplicated requests. One example is the ChipIdea controller implementation in U-Boot: The second SET_CONFIGURATION request makes U-Boot disable and re-enable all endpoints. Re-enabling an endpoint in the ChipIdea controller, however, was broken until U-Boot commit b272c8792502 ("usb: ci: Fix gadget reinit").

commit ddfcfeba891064b88bb844208b43bef2ef970f0c upstream. The probe function never performs any paltform device allocation, thus error path "undo_platform_dev_alloc" is entirely bogus. It drops the reference count from the platform device being probed. If error path is triggered, this will lead to unbalanced device reference counts and premature release of device resources, thus possible use-after-free when releasing remaining devm-managed resources.

2024-09-04usb: dwc3: core: Prevent USB core invalid event buffer address accessSelvarasu Ganesan1-0/+8
commit 14e497183df28c006603cc67fd3797a537eef7b9 upstream. This commit addresses an issue where the USB core could access an invalid event buffer address during runtime suspend, potentially causing SMMU faults and other memory issues in Exynos platforms. The problem arises from the following sequence. 1. In dwc3_gadget_suspend, there is a chance of a timeout when moving the USB core to the halt state after clearing the run/stop bit by software. 2. In dwc3_core_exit, the event buffer is cleared regardless of the USB core's status, which may lead to an SMMU faults and other memory issues. if the USB core tries to access the event buffer address. To prevent this hardware quirk on Exynos platforms, this commit ensures that the event buffer address is not cleared by software when the USB core is active during runtime suspend by checking its status before clearing the buffer address.

2024-09-04soc: qcom: cmd-db: Map shared memory as WC, not WBVolodymyr Babchuk1-1/+1
commit f9bb896eab221618927ae6a2f1d566567999839d upstream. Linux does not write into cmd-db region. This region of memory is write protected by XPU. XPU may sometime falsely detect clean cache eviction as "write" into the write protected region leading to secure interrupt which causes an endless loop somewhere in Trust Zone. The only reason it is working right now is because Qualcomm Hypervisor maps the same region as Non-Cacheable memory in Stage 2 translation tables. The issue manifests if we want to use another hypervisor (like Xen or KVM), which does not know anything about those specific mappings. Changing the mapping of cmd-db memory from MEMREMAP_WB to MEMREMAP_WT/WC removes dependency on correct mappings in Stage 2 tables. This patch fixes the issue by updating the mapping to MEMREMAP_WC. I tested this on SA8155P with Xen.

2024-09-04nfc: pn533: Add poll mod list filling checkAleksandr Mishin1-0/+5
[ Upstream commit febccb39255f9df35527b88c953b2e0deae50e53 ] In case of im_protocols value is 1 and tm_protocols value is 0 this combination successfully passes the check 'if (!im_protocols && !tm_protocols)' in the nfc_start_poll(). But then after pn533_poll_create_mod_list() call in pn533_start_poll() poll mod list will remain empty and dev->poll_mod_count will remain 0 which lead to division by zero. Normally no im protocol has value 1 in the mask, so this combination is not expected by driver. But these protocol values actually come from userspace via Netlink interface (NFC_CMD_START_POLL operation). So a broken or malicious program may pass a message containing a "bad" combination of protocol parameter values so that dev->poll_mod_count is not incremented inside pn533_poll_create_mod_list(), thus leading to division by zero. Call trace looks like: nfc_genl_start_poll() nfc_start_poll() ->start_poll() pn533_start_poll() Add poll mod list filling check. Found by Linux Verification Center (linuxtesting.org) with SVACE.

2024-09-04soundwire: stream: fix programming slave ports for non-continous port mapsKrzysztof Kozlowski1-4/+4
commit ab8d66d132bc8f1992d3eb6cab8d32dda6733c84 upstream. Two bitmasks in 'struct sdw_slave_prop' - 'source_ports' and 'sink_ports' - define which ports to program in sdw_program_slave_port_params(). The masks are used to get the appropriate data port properties ('struct sdw_get_slave_dpn_prop') from an array. Bitmasks can be non-continuous or can start from index different than 0, thus when looking for matching port property for given port, we must iterate over mask bits, not from 0 up to number of ports. This fixes allocation and programming slave ports, when a source or sink masks start from further index.

commit be4a2a81b6b90d1a47eaeaace4cc8e2cb57b96c7 upstream. We don't get the right offset in that case. The GPU has an unused 4K area of the register BAR space into which you can remap registers. We remap the HDP flush registers into this space to allow userspace (CPU or GPU) to flush the HDP when it updates VRAM. However, on systems with >4K pages, we end up exposing PAGE_SIZE of MMIO space.

2024-09-04HID: microsoft: Add rumble support to latest xbox controllersSiarhei Vishniakou2-2/+19
commit f5554725f30475b05b5178b998366f11ecb50c7f upstream. Currently, rumble is only supported via bluetooth on a single xbox controller, called 'model 1708'. On the back of the device, it's named 'wireless controller for xbox one'. However, in 2021, Microsoft released a firmware update for this controller. As part of this update, the HID descriptor of the device changed. The product ID was also changed from 0x02fd to 0x0b20. On this controller, rumble was supported via hid-microsoft, which matched against the old product id (0x02fd). As a result, the firmware update broke rumble support on this controller. See: https://news.xbox.com/en-us/2021/09/08/xbox-controller-firmware-update-rolling-out-to-insiders-starting-today/ The hid-microsoft driver actually supports rumble on the new firmware, as well. So simply adding new product id is sufficient to bring back this support. After discussing further with the xbox team, it was pointed out that another xbox controller, xbox elite series 2, can be supported in a similar way. Add rumble support for all of these devices in this patch. Two of the devices have received firmware updates that caused their product id's to change. Both old and new firmware versions of these devices were tested. The tested controllers are: 1. 'wireless controller for xbox one', model 1708 2. 'xbox wireless controller', model 1914. This is also sometimes referred to as 'xbox series S|X'. 3. 'elite series 2', model 1797. The tested configurations are: 1. model 1708, pid 0x02fd (old firmware) 2. model 1708, pid 0x0b20 (new firmware) 3. model 1914, pid 0x0b13 4. model 1797, pid 0x0b05 (old firmware) 5. model 1797, pid 0x0b22 (new firmware) I verified rumble support on both bluetooth and usb.

2024-09-04HID: wacom: Defer calculation of resolution until resolution_code is knownJason Gerecke1-1/+3
commit 1b8f9c1fb464968a5b18d3acc1da8c00bad24fad upstream. The Wacom driver maps the HID_DG_TWIST usage to ABS_Z (rather than ABS_RZ) for historic reasons. When the code to support twist was introduced in commit 50066a042da5 ("HID: wacom: generic: Add support for height, tilt, and twist usages"), we were careful to write it in such a way that it had HID calculate the resolution of the twist axis assuming ABS_RZ instead (so that we would get correct angular behavior). This was broken with the introduction of commit 08a46b4190d3 ("HID: wacom: Set a default resolution for older tablets"), which moved the resolution calculation to occur *before* the adjustment from ABS_Z to ABS_RZ occurred. This commit moves the calculation of resolution after the point that we are finished setting things up for its proper use.

[ Upstream commit df24373435f5899a2a98b7d377479c8d4376613b ] DPU debugging macros need to be converted to a proper drm_debug_* macros, however this is a going an intrusive patch, not suitable for a fix. Wire DPU_DEBUG and DPU_DEBUG_DRIVER to always use DRM_DEBUG_DRIVER to make sure that DPU debugging messages always end up in the drm debug messages and are controlled via the usual drm.debug mask. I don't think that it is a good idea for a generic DPU_DEBUG macro to be tied to DRM_UT_KMS. It is used to report a debug message from driver, so by default it should go to the DRM_UT_DRIVER channel. While refactoring debug macros later on we might end up with particular messages going to ATOMIC or KMS, but DRIVER should be the default.
