2026-07-07staging: octeon: add missing napi_disable in cvm_oct_rx_shutdownAyush Mukkanwar
cvm_oct_rx_shutdown calls free_irq and netif_napi_del without disabling the napi instance first. As the free_irq only waits for completion of hard interrupt handlers, the napi poll function could still be active. If cvm_oct_remove proceeds to free the plat structure (which holds the NAPI instances), the active poll function will access freed memory, resulting in a use-after-free crash.

2026-07-07staging: octeon: add missing tasklet_kill in cvm_oct_tx_shutdownAyush Mukkanwar
The TX cleanup tasklet can be scheduled by the watchdog IRQ handler to execute cvm_oct_tx_do_cleanup. There can be a pending tasklet in the queue which might run after the cvm_oct_remove() frees net_device structures, causing a use-after-free in cvm_oct_tx_do_cleanup() as it iterates cvm_oct_device[] which is an array of netdevice pointers. Add tasklet_kill() after free_irq() to ensure the tasklet is no longer scheduled or running before teardown proceeds.

__gb_hid_output_raw_report() stores the result of gb_hid_set_report() in ret and even adjusts it to account for the report ID byte, but then always returns 0. This hides Greybus transport errors from HID_REQ_SET_REPORT callers, and makes hidraw report zero bytes written to user space on success, although hid_hw_raw_request() is expected to return the number of bytes transferred or a negative errno.

2026-07-07greybus: audio: bound the topology section sizes against the fetched sizeBryam Vargas
gb_audio_gb_get_topology() fetches a topology blob of a module-supplied size, and gbaudio_tplg_parse_data() then walks it by adding the module-supplied size_dais, size_controls and size_widgets fields to form the control, widget and route section offsets. Those le32 sizes are never checked against the fetched blob, so a module reporting a small topology size but large section sizes makes the offsets point past the allocation, and parsing reads out of bounds.

2026-07-07staging: sm750fb: gate dualview dataflow using g_dualviewAhmet Sezgin Duran
In sm750fb_setup and sm750fb_set_drv functions, the dualview related code is guarded by `sm750_dev->fb_count > 1` condition. That value is updated only after each framebuffer is registered, while both guards are used before any increment. Current flow: lynxfb_pci_probe() sm750fb_setup() // fb_count is 0 for each fb: sm750fb_framebuffer_alloc() lynxfb_set_fbinfo() sm750fb_set_drv() // fb_count is 0 or 1 register_framebuffer() sm750_dev->fb_count++; // fb_count is incremented Thus even if `dualview=1` parameter is passed down to the driver, fb_count is never > 1 at either check, so dualview dataflows are not selected and crtc->vidmem_size is never halved. Use `g_dualview` global variable instead of fb_count > 1 to correctly enable dualview capabilities.

2026-07-07net/liquidio: drop cached VF pci_dev LUTYuho Choi
The PF SR-IOV enable path caches VF pci_dev pointers in dpiring_to_vfpcidev_lut[] by iterating with pci_get_device(). Those entries do not own a reference, because the iterator drops the previous device reference on each step. The cached pointer is then dereferenced later when handling OCTEON_VF_FLR_REQUEST. Replace the cached VF mapping with runtime lookup on the mailbox DPI ring: derive the VF index from q_no, resolve the VF via exported PCI IOV helpers, validate it with the PF pointer and VF ID, then issue pcie_flr() and drop the reference with pci_dev_put(). Remove the unused VF lookup table initialization and cleanup.

2026-07-07net: rnpgbe: fix mailbox endianness and remove pointer castsDong Yibo
The rnpgbe mailbox exchanges data through 32-bit MMIO registers in little-endian wire format. The original code had two problems: 1. FW structs (with __le16/__le32 fields) were cast to (u32 *) before reaching the mailbox transport, hiding the endian annotations from sparse. 2. No cpu_to_le32()/le32_to_cpu() conversion was done between CPU-endian MMIO values and the little-endian payload, causing data corruption on big-endian systems. Fix by adding the missing byte-order conversions in the transport layer and introducing union wrappers (mbx_fw_cmd_req_u, mbx_fw_cmd_reply_u) that overlay each FW struct with a __le32 dwords[] array. Callers fill named fields using cpu_to_le16/32(), then pass dwords[] to the transport, which now takes explicit __le32 * instead of u32 *. This eliminates all pointer casts on the mailbox data path and lets sparse verify the conversions.

2026-07-07wifi: brcmfmac: cyw: fix heap overflow on a short auth frameMaoyi Xie
brcmf_notify_auth_frame_rx() takes the frame length from the firmware event and copies the frame body with the management header offset subtracted: u32 mgmt_frame_len = e->datalen - sizeof(struct brcmf_rx_mgmt_data); ... memcpy(&mgmt_frame->u, frame, mgmt_frame_len - offsetof(struct ieee80211_mgmt, u)); The only length check is e->datalen >= sizeof(*rxframe), so mgmt_frame_len can be anything from 0 up. offsetof(struct ieee80211_mgmt, u) is 24. When mgmt_frame_len is below that, the subtraction wraps as an unsigned value to a huge length. The memcpy then runs far past the kzalloc'd buffer. A malicious or malfunctioning AP can make the frame short during the external SAE auth exchange, so this is a remotely triggered heap overflow. Reject frames shorter than the management header offset before the copy.

mac80211_hwsim_stop() drops any frames left in data->pending. The loop currently checks skb_queue_empty() and then dequeues separately. That split is racy with TX status handling, which can remove a pending frame under the queue lock. If the last entry is removed after the empty check, skb_dequeue() returns NULL and the stop path passes that NULL skb to ieee80211_free_txskb(). Use skb_dequeue() as the loop condition instead.

2026-07-07wifi: brcmfmac: initialize SDIO data work before cleanupRunyu Xiao
brcmf_sdio_probe() stores the newly allocated bus in sdiodev->bus before allocating the ordered workqueue. If that allocation fails, the function jumps to fail and calls brcmf_sdio_remove(). brcmf_sdio_remove() unconditionally cancels bus->datawork. Initialize the work item before the first failure path that can reach brcmf_sdio_remove(), so the cleanup path always observes a valid work object. This issue was found by our static analysis tool and then confirmed by manual review of the probe error path and the remove-time work drain. The problem pattern is an early setup failure that reaches a cleanup helper which cancels an embedded work item before its initializer has run. A QEMU PoC forced alloc_ordered_workqueue() to fail at the same point in brcmf_sdio_probe(), before INIT_WORK(&bus->datawork) is reached. The resulting fail path calls brcmf_sdio_remove(), and DEBUG_OBJECTS reports the invalid work drain with brcmf_sdio_probe() and brcmf_sdio_remove() in the stack.

2026-07-06accel/amdxdna: Prevent PM resume deadlock in hwctx_sync_debug_bo()Lizhi Hou
amdxdna_hwctx_sync_debug_bo() invokes the hardware hwctx_sync_debug_bo() callback while holding xdna->dev_lock. The callback may call amdxdna_cmd_submit(), which in turn calls amdxdna_pm_resume_get(). If the device is suspended, amdxdna_pm_resume_get() may synchronously execute amdxdna_pm_resume(), which also acquires xdna->dev_lock, resulting in a deadlock. Avoid the deadlock by calling amdxdna_pm_resume_get() before holding xdna->dev_lock in both amdxdna_hwctx_sync_debug_bo() and amdxdna_drm_config_hwctx_ioctl() Fixes: 7ea046838021 ("accel/amdxdna: Support firmware debug buffer") Reviewed-by: Max Zhen <max.zhen@amd.com> Signed-off-by: Lizhi Hou <lizhi.hou@amd.com> Link: https://patch.msgid.link/20260616212429.3620645-1-lizhi.hou@amd.com
2026-07-07PCI: qcom: Skip PERST# GPIOs provided by downstream PCIe devicesManivannan Sadhasivam
Currently, the pcie-qcom driver recursively parses the PERST# GPIO from all child nodes defined in DT and acquires them. But this creates issues with PERST# GPIO provided by one of the child devices like the PCIe switch port. In this case, the RC driver cannot acquire the PERST# GPIO since it will be provided by the child PCIe device which was not yet enumerated during RC driver probe. Fix this by checking if the GPIO provider is a child of the RC's DT node (i.e., sits behind this PCIe controller). If so, skip it, as PERST# should be controlled by the respective PCIe client driver implementation. GPIOs provided by external GPIO controllers (e.g., TLMM in Qcom SoCs) continue to be handled normally.

2026-07-07fpga: xilinx-pr-decoupler: Use devm_clk_get_prepared()Michal Simek
The driver keeps the "aclk" clock prepared but disabled in its idle state, toggling only the atomic clk_enable()/clk_disable() around register accesses in the bridge enable_set/enable_show callbacks. At probe time this was open-coded as clk_prepare_enable() immediately followed by clk_disable(), leaving the clock prepared, with a matching clk_unprepare() in the error path and in remove(). devm_clk_get_prepared() expresses exactly this: it gets and prepares the clock and unprepares it automatically on driver detach. Use it to drop the manual prepare/disable dance, the error-path unprepare, and the now-empty clock teardown in remove().

The gcc_eva_ahb_clk and gcc_eva_xo_clk branch clocks should not be registered as standalone GCC branch clocks. Drop these clocks from the GCC clock list and instead add their CBCR registers to the GCC critical clocks list to ensure they remain enabled during early boot. If these clocks are registered as normal branch clocks, they may be gated, which breaks access to the EVA clock controller during clock controller probe, thus leave them as critical clocks similar to other subsystem AHB and XO clocks.
