[PATCH] EDAC: altera: Delete an inappropriate dma_free_coherent() call in altr_sdr_mc_err_inject_write()

by Salah Triki

`dma_free_coherent()` must only be called if the corresponding `dma_alloc_coherent()` call has succeeded. Calling it when the allocation fails leads to undefined behavior. Add a check to ensure that the memory is only freed when the allocation was successful.

[PATCH V2] drm/amdgpu: check return value of xa_store()

by Salah Triki

The `xa_store()` function can fail due to memory allocation issues or other internal errors. Currently, the return value of `xa_store()` is not checked, which can lead to a memory leak if it fails to store `numa_info`. This patch checks the return value of `xa_store()`. If an error is detected, the allocated `numa_info` is freed, and NULL is returned to indicate the failure, preventing a memory leak and ensuring proper error handling.

[PATCH 0/6] rockchip: puma-rk3399: anticipate breakage with v6.16 DT

by Quentin Schulz

Due to updates to the Device Tree (migrating to onboard USB hub nodes instead of (badly) hacking things with a gpio regulator that doesn't actually work properly), we now need to enable the onboard USB hub driver in U-Boot. This anticipates upcoming breakage when 6.16 DT will be merged into U-Boot's dts/upstream. The series can be applied as is before v6.16 DT is merged or only the defconfig changes after 6.16 DT has been merged. The last two patches are simply to avoid probing devices that aren't actually routed on RK3399 Puma, which is nice to have but doesn't fix anything. Note that this depends on the following series: https://lore.kernel.org/u-boot/20250722-usb_onboard_hub_cypress_hx3-v4-0-91… Signed-off-by: Quentin Schulz <quentin.schulz(a)cherry.de> --- Lukasz Czechowski (2): dt-bindings: usb: cypress,hx3: Add support for all variants arm64: dts: rockchip: fix internal USB hub instability on RK3399 Puma Quentin Schulz (4): configs: puma-rk3399: enable onboard USB hub support dt-bindings: usb: usb-device: relax compatible pattern to a contains arm64: dts: rockchip: disable unrouted USB controllers and PHY on RK3399 Puma arm64: dts: rockchip: disable unrouted USB controllers and PHY on RK3399 Puma with Haikou configs/puma-rk3399_defconfig | 1 + dts/upstream/Bindings/usb/cypress,hx3.yaml | 19 +++++++-- dts/upstream/Bindings/usb/usb-device.yaml | 3 +- .../src/arm64/rockchip/rk3399-puma-haikou.dts | 8 ---- dts/upstream/src/arm64/rockchip/rk3399-puma.dtsi | 48 +++++++++++----------- 5 files changed, 43 insertions(+), 36 deletions(-) --- base-commit: 5a8dd2e0c848135b5c96af291aa96e79acc923ec change-id: 20250730-puma-usb-cypress-2d2957024424 prerequisite-change-id: 20250425-usb_onboard_hub_cypress_hx3-2831983f1ede:v4 prerequisite-patch-id: 515a13b22600d40716e9c36d16b084086ce7d474 prerequisite-patch-id: 9f8a11bd6c66e976c51dc0f0bc3292183f9403f3 prerequisite-patch-id: 45ef5b9422333db5fcd23d95b6570b320635c49b prerequisite-patch-id: 19092f1c3db746292401b8513807439c87ea9589 prerequisite-patch-id: fced7578d40069c5fe83d97aa42476015cf9cbda Best regards, -- Quentin Schulz <quentin.schulz(a)cherry.de>

[PATCH 5.15.y 0/4] Backport series: "permit write-sealed memfd read-only shared mappings"

by Isaac J. Manjarres

Hello, Until kernel version 6.7, a write-sealed memfd could not be mapped as shared and read-only. This was clearly a bug, and was not inline with the description of F_SEAL_WRITE in the man page for fcntl()[1]. Lorenzo's series [2] fixed that issue and was merged in kernel version 6.7, but was not backported to older kernels. So, this issue is still present on kernels 5.4, 5.10, 5.15, 6.1, and 6.6. This series consists of backports of two of Lorenzo's series [2] and [3]. Note: for [2], I dropped the last patch in that series, since it wouldn't make sense to apply it due to [4] being part of this tree. In lieu of that, I backported [3] to ultimately allow write-sealed memfds to be mapped as read-only.

[PATCH v2 6.6.y] mm: khugepaged: fix call hpage_collapse_scan_file() for anonymous vma

by Jakub Acs

From: Liu Shixin <liushixin2(a)huawei.com> commit f1897f2f08b28ae59476d8b73374b08f856973af upstream. syzkaller reported such a BUG_ON(): ------------[ cut here ]------------ kernel BUG at mm/khugepaged.c:1835!

After analysis, I confirm the vma is mapped to /dev/zero. Such a vma certainly has vm_file, but it is set to anonymous by mmap_zero(). So even if it's mmapped by 2m-unaligned, it can pass the check in thp_vma_allowable_order() as it is an anonymous-mmap, but then be collapsed as a file-mmap. It seems the problem has existed for a long time, but actually, since we have khugepaged_max_ptes_none check before, we will skip collapse it as it is /dev/zero and so has no present page. But commit d8ea7cc8547c limit the check for only khugepaged, so the BUG_ON() can be triggered by madvise_collapse(). Add vma_is_anonymous() check to make such vma be processed by hpage_collapse_scan_pmd().
