2025-10-02ASoC: SOF: ipc3-topology: Fix multi-core and static pipelines tear downRanjani Sridharan
In the case of static pipelines, freeing the widgets in the pipelines that were not suspended after freeing the scheduler widgets results in errors because the secondary cores are powered off when the scheduler widgets are freed. Fix this by tearing down the leftover pipelines before powering off the secondary cores.

While the helper currently returns -EINVAL in most cases, passing through the real error code is more future-proof. While at it, drop the stray 'intel:' prefix from the error message.

2025-10-02drm/gpusvm, drm/xe: Fix userptr to not allow device private pagesThomas Hellström
When userptr is used on SVM-enabled VMs, a non-NULL hmm_range::dev_private_owner value might mean that hmm_range_fault() attempts to return device private pages. Either that will fail, or the userptr code will not know how to handle those. Use NULL for hmm_range::dev_private_owner to migrate such pages to system. In order to do that, move the struct drm_gpusvm::device_private_page_owner field to struct drm_gpusvm_ctx::device_private_page_owner so that it doesn't remain immutable over the drm_gpusvm lifetime. v2: - Don't conditionally compile xe_svm_devm_owner(). - Kerneldoc xe_svm_devm_owner().

2025-10-01cifs: client: force multichannel=off when max_channels=1Rajasi Mandal
Previously, specifying both multichannel and max_channels=1 as mount options would leave multichannel enabled, even though it is not meaningful when only one channel is allowed. This led to confusion and inconsistent behavior, as the client would advertise multichannel capability but never establish secondary channels. Fix this by forcing multichannel to false whenever max_channels=1, ensuring the mount configuration is consistent and matches user intent. This prevents the client from advertising or attempting multichannel support when it is not possible.

2025-10-01smb: client: transport: avoid reconnects triggered by pending task workFiona Ebner
When io_uring is used in the same task as CIFS, there might be unnecessary reconnects, causing issues in user-space applications like QEMU with a log like: > CIFS: VFS: \\10.10.100.81 Error -512 sending data on socket to server Certain io_uring completions might be added to task_work with notify_method being TWA_SIGNAL and thus TIF_NOTIFY_SIGNAL is set for the task. In __smb_send_rqst(), signals are masked before calling smb_send_kvec(), but the masking does not apply to TIF_NOTIFY_SIGNAL. If sk_stream_wait_memory() is reached via sock_sendmsg() while TIF_NOTIFY_SIGNAL is set, signal_pending(current) will evaluate to true there, and -EINTR will be propagated all the way from sk_stream_wait_memory() to sock_sendmsg() in smb_send_kvec().

2025-10-01smb: client: remove unused fid_lockHenrique Carvalho
The fid_lock in struct cached_fid does not currently provide any real synchronization. Previously, it had the intention to prevent a double release of the dentry, but every change to cfid->dentry is already protected either by cfid_list_lock (while the entry is in the list) or happens after the cfid has been removed (so no other thread should find it). Since there is no scenario in which fid_lock prevents any race, it is vestigial and can be removed along with its associated spin_lock()/spin_unlock() calls.

Pull SoC dt updates from Arnd Bergmann: "There are five sets of new SoCs that get added in existing families, all of them being either upgrades or cut-down versions of the older chips: - Apple M2 Pro, M2 Max and M2 Ultra, used in the 2022/2023 generation of high-end workstations and laptops from Apple. Linux has been working on these for a while but stil requires patches. - Axis Artpec8 is an Armv8 chip based on Samsung Exynos design, unlike the earlier Armv7 Artpec6 from the same company that was part of a separate family of chips. - NXP i.MX91 is a cut-down version of i.MX93, using only a single Cortex-A55 core. - Qualcomm Lemans Auto is a variant of the Lemans SoC that was originally merged under the sa8775p name, the differences being mostly the firmware configuration of the platform. - Four new Renesas SoCs RZ/T2H (r9a09g077m44), RZ/N2H (r9a09g087m44), RZ/T2H (r9a09g077), and RZ/N2H (r9a09g087) are all industrial bedded SoCs based on Cortex-A55 cores In total, there are 65 new machines, including: - Industrial embedded system and single-board computers based on NXP, Allwinner, TI, Rockchips, Marvell, Xilinx Spacemit, Starfive chips. - Reference boards for the newly added Renesas, Qualcomm, NXP and Axis ARMv8 chips as well as Microchip's MPFS RISC-V SoC - Laptops and Workstations using Apple M2 and Qualcomm Snapdragon X1 chips. - Several Samsung phones using Qualcomm Snapdragon chips - Set-top boxes based on Allwinner H313 - Five BMC boards using 32-bit ASpeed SoCs - Three network routers using IXP4xx (ARMv5!) and Broadcom bcm4708 (ARMv7) SoCs Two machines get phased out because they were available only in small quantities but never made it into products: one STi407 based reference board, and a Snapdragon 845 based Chromebook.

2025-10-01bpf: Reject negative offsets for ALU opsYazhou Tang
When verifying BPF programs, the check_alu_op() function validates instructions with ALU operations. The 'offset' field in these instructions is a signed 16-bit integer. The existing check 'insn->off > 1' was intended to ensure the offset is either 0, or 1 for BPF_MOD/BPF_DIV. However, because 'insn->off' is signed, this check incorrectly accepts all negative values (e.g., -1). This commit tightens the validation by changing the condition to '(insn->off != 0 && insn->off != 1)'. This ensures that any value other than the explicitly permitted 0 and 1 is rejected, hardening the verifier against malformed BPF programs.

2025-10-01Merge branch 'libbpf-fix-libbpf_sha256-for-github-compatibility'Alexei Starovoitov
Andrii Nakryiko says: ==================== libbpf: fix libbpf_sha256() for Github compatibility Recent reimplementation of libbpf_sha256() introduced issues for libbpf's Github mirror due to reliance on linux/unaligned.h header. This patch set fixes those issues to make libbpf source code compatible with Github mirror setup. This patch set starts with a bit of organization: we introduce libbpf_utils.c as a place for generic internal helpers like libbpf_errstr() and libbpf_sha256(), and move a few existing helpers there. We also clean up libbpf_strerror_r(), which seems to be a leftover of some previous refactorings. And finally, we move libbpf_sha256() from huge libbpf.c into libbpf_utils.c, following up with fix ups to make its code more Github-friendly. v1->v2: - add missed cpu_to_be32() and be32_to_cpu() conversions inside {get/put}_unaligned_be32() macros; - target bpf tree (Alexei); - applied Eric's libbpf_sha256 selftest locally and verified it works; v1: https://lore.kernel.org/bpf/20250930212619.1645410-1-andrii@kernel.org/ ==================== Link: https://patch.msgid.link/20251001171326.3883055-1-andrii@kernel.org Signed-off-by: Alexei Starovoitov <ast@kernel.org>
2025-10-01libbpf: remove linux/unaligned.h dependency for libbpf_sha256()Andrii Nakryiko
linux/unaligned.h include dependency is causing issues for libbpf's Github mirror due to {get,put}_unaligned_be32() usage. So get rid of it by implementing custom variants of those macros that will work both in kernel and Github mirror repos. Also switch round_up() to roundup(), as the former is not available in Github mirror (and is just a subtly more specific variant of roundup() anyways).
