2025-08-15crypto: sun8i-ce - fix nents passed to dma_unmap_sg()Ovidiu Panait1-2/+2
[ Upstream commit b6cd3cfb5afe49952f8f6be947aeeca9ba0faebb ] In sun8i_ce_cipher_unprepare(), dma_unmap_sg() is incorrectly called with the number of entries returned by dma_map_sg(), rather than using the original number of entries passed when mapping the scatterlist. To fix this, stash the original number of entries passed to dma_map_sg() in the request context.

[ Upstream commit 715676d8418062f54d746451294ccce9786c1734 ] Commit bc4d25fdfadf ("clk: renesas: rzv2h: Add support for dynamic switching divider clocks") missed setting the `CLK_SET_RATE_PARENT` flag when registering ddiv clocks.

2025-08-15staging: media: atomisp: Fix stack buffer overflow in gmin_get_var_int()Kees Cook1-4/+5
[ Upstream commit ee4cf798202d285dcbe85e4467a094c44f5ed8e6 ] When gmin_get_config_var() calls efi.get_variable() and the EFI variable is larger than the expected buffer size, two behaviors combine to create a stack buffer overflow: 1. gmin_get_config_var() does not return the proper error code when efi.get_variable() fails. It returns the stale 'ret' value from earlier operations instead of indicating the EFI failure. 2. When efi.get_variable() returns EFI_BUFFER_TOO_SMALL, it updates *out_len to the required buffer size but writes no data to the output buffer. However, due to bug #1, gmin_get_var_int() believes the call succeeded. The caller gmin_get_var_int() then performs: - Allocates val[CFG_VAR_NAME_MAX + 1] (65 bytes) on stack - Calls gmin_get_config_var(dev, is_gmin, var, val, &len) with len=64 - If EFI variable is >64 bytes, efi.get_variable() sets len=required_size - Due to bug #1, thinks call succeeded with len=required_size - Executes val[len] = 0, writing past end of 65-byte stack buffer This creates a stack buffer overflow when EFI variables are larger than 64 bytes. Since EFI variables can be controlled by firmware or system configuration, this could potentially be exploited for code execution. Fix the bug by returning proper error codes from gmin_get_config_var() based on EFI status instead of stale 'ret' value. The gmin_get_var_int() function is called during device initialization for camera sensor configuration on Intel Bay Trail and Cherry Trail platforms using the atomisp camera stack.

2025-08-15stmmac: xsk: fix negative overflow of budget in zerocopy modeJason Xing1-1/+1
[ Upstream commit 2764ab51d5f0e8c7d3b7043af426b1883e3bde1d ] A negative overflow can happen when the budget number of descs are consumed. as long as the budget is decreased to zero, it will again go into while (budget-- > 0) statement and get decreased by one, so the overflow issue can happen. It will lead to returning true whereas the expected value should be false. In this case where all the budget is used up, it means zc function should return false to let the poll run again because normally we might have more data to process. Without this patch, zc function would return true instead.

2025-08-15net/mlx5e: Remove skb secpath if xfrm state is not foundJianbo Liu1-0/+4
[ Upstream commit 6d19c44b5c6dd72f9a357d0399604ec16a77de3c ] Hardware returns a unique identifier for a decrypted packet's xfrm state, this state is looked up in an xarray. However, the state might have been freed by the time of this lookup. Currently, if the state is not found, only a counter is incremented. The secpath (sp) extension on the skb is not removed, resulting in sp->len becoming 0. Subsequently, functions like __xfrm_policy_check() attempt to access fields such as xfrm_input_state(skb)->xso.type (which dereferences sp->xvec[sp->len - 1]) without first validating sp->len. This leads to a crash when dereferencing an invalid state pointer. This patch prevents the crash by explicitly removing the secpath extension from the skb if the xfrm state is not found after hardware decryption. This ensures downstream functions do not operate on a zero-length secpath.

Because of this, as part of the scan request handler for the P2P Discovery, vif struct used for adding the Probe Request P2P IE in firmware got changed from the P2PAPI_BSSCFG_DEVICE vif to P2PAPI_BSSCFG_PRIMARY vif incorrectly. So the firmware stopped adding P2P IE to the outgoing P2P Discovery probe requests frames and the other P2P peers were unable to discover this device causing a regression on the P2P feature. To fix this, while setting the P2P IE in firmware, properly use the vif of the P2P discovery wdev on which the driver received the P2P scan request. This is done by not changing the vif pointer, until brcmf_vif_set_mgmt_ie() is completed.

2025-08-15iommu/amd: Fix geometry.aperture_end for V2 tablesJason Gunthorpe1-2/+15
[ Upstream commit 8637afa79cfa6123f602408cfafe8c9a73620ff1 ] The AMD IOMMU documentation seems pretty clear that the V2 table follows the normal CPU expectation of sign extension. This is shown in Figure 25: AMD64 Long Mode 4-Kbyte Page Address Translation Where bits Sign-Extend [63:57] == [56]. This is typical for x86 which would have three regions in the page table: lower, non-canonical, upper. The manual describes that the V1 table does not sign extend in section 2.2.4 Sharing AMD64 Processor and IOMMU Page Tables GPA-to-SPA Further, Vasant has checked this and indicates the HW has an addtional behavior that the manual does not yet describe. The AMDv2 table does not have the sign extended behavior when attached to PASID 0, which may explain why this has gone unnoticed. The iommu domain geometry does not directly support sign extended page tables. The driver should report only one of the lower/upper spaces. Solve this by removing the top VA bit from the geometry to use only the lower space. This will also make the iommu_domain work consistently on all PASID 0 and PASID != 1. Adjust dma_max_address() to remove the top VA bit.

That's fine for the case when all we are doing is returning that descriptor to userland (it's a race, but it's a userland race and there's nothing the kernel can do about it). However, if we follow fd_install() with any kind of access to objects that would be destroyed on close (be it the struct file itself or anything destroyed by its ->release()), we have a UAF. dma_buf_fd() is a combination of reserving a descriptor and fd_install(). gntdev dmabuf_exp_from_pages() calls it and then proceeds to access the objects destroyed on close - starting with gntdev_dmabuf itself. Fix that by doing reserving descriptor before anything else and do fd_install() only when everything had been set up.

[ Upstream commit c4f96972c3c206ac8f6770b5ecd5320b561d0058 ] When changing the page size on an mkey, the driver needs to set the appropriate bits in the mkey mask to indicate which fields are being modified. The 6th bit of a page size in mlx5 driver is considered an extension, and this bit has a dedicated capability and mask bits. Previously, the driver was not setting this mask in the mkey mask when performing page size changes, regardless of its hardware support, potentially leading to an incorrect page size updates. This fixes the issue by setting the relevant bit in the mkey mask when performing page size changes on an mkey and the 6th bit of this field is supported by the hardware.

2025-08-15cpufreq: intel_pstate: Always use HWP_DESIRED_PERF in passive modeRafael J. Wysocki1-2/+2
[ Upstream commit 1cefe495cacba5fb0417da3a75a1a76e3546d176 ] In the passive mode, intel_cpufreq_update_pstate() sets HWP_MIN_PERF in accordance with the target frequency to ensure delivering adequate performance, but it sets HWP_DESIRED_PERF to 0, so the processor has no indication that the desired performance level is actually equal to the floor one. This may cause it to choose a performance point way above the desired level. Moreover, this is inconsistent with intel_cpufreq_adjust_perf() which actually sets HWP_DESIRED_PERF in accordance with the target performance value. Address this by adjusting intel_cpufreq_update_pstate() to pass target_pstate as both the minimum and the desired performance levels to intel_cpufreq_hwp_update().
