[PATCH openEuler-1.0-LTS 0/2] loop: fix UAF in mutex_spin_on_owner()
by Zheng Qixing 19 Apr '25

19 Apr '25

The error path in loop_set_status() fails to release the loop_ctl_mutex lock, causing a UAF issue in mutex_spin_on_owner() when other processes attempt to access the same loop device.

[PATCH v2 OLK-5.10 0/2] mm: arm64: Add NUMA kernel and user replication feature
by Nikita Panov 18 Apr '25

18 Apr '25

Initial support for NUMA RO-data replication. You can enable replication for a specific process or for a whole memory cgroup. Processes: /proc/$PID/numa_table_replication 0 - table replication disabled. 1 - tables for RO-data are replicated. 2 - all tables are replicated. /proc/$PID/numa_data_replication 0 - data is not replicated. 1 - hot RO-data is replicated. 2 - all RO-data is replicated. (May not work properly now, avoid if possible) Cgroups: /sys/fs/cgroup/memeory/$CGNAME/memory.numa_table_replication same as for processes. /sys/fs/cgroup/memeory/$CGNAME/memory.numa_data_replication 0 - data is not replicated. 1 - hot RO-data is replicated. 2 - hot RO-data is replicated and on adding to cgroup all existing RO-data of a process is replicated. 3 - all RO-data is replicated. (May not work properly now, avoid if possible) Entry numa_replication_stats shows the amount of replicated data in a process or a cgroup.

[PATCH OLK-6.6 0/8] iommu/arm-smmu-v3: Use KVM VMID for s2 stage
by lishusen 18 Apr '25

18 Apr '25

On an ARM64 system with a SMMUv3 implementation that fully supports Broadcast TLB Maintenance(BTM) feature as part of the Distributed Virtual Memory(DVM) protocol, the CPU TLB invalidate instructions are received by SMMUv3. This is very useful when the SMMUv3 shares the page tables with the CPU(eg: Guest SVA use case). For this to work, the SMMUv3 must use the same VMID that is allocated by KVM to configure the nested stage 2(S2) translations. Jean-Philippe Brucker (1): iommu/arm-smmu-v3: Enable broadcast TLB maintenance Kunkun Jiang (1): vfio: Fix kabi breakage due to closing VFIO_CONTAINER Shameer Kolothum (6): KVM: Add generic infrastructure to support pinned VMIDs KVM: arm64: Introduce support to pin VMIDs KVM: arm64: Add interfaces for pinned VMID support iommufd: Associate kvm pointer to iommufd ctx iommu: Pass in kvm pointer to domain_alloc_user iommu/arm-smmu-v3: Use KVM VMID for s2 stage arch/arm64/include/asm/kvm_host.h | 3 + arch/arm64/kvm/Kconfig | 1 + arch/arm64/kvm/arm.c | 14 ++++ arch/arm64/kvm/vmid.c | 84 ++++++++++++++++++++- drivers/iommu/amd/iommu.c | 1 + drivers/iommu/arm/arm-smmu-v3/arm-smmu-v3.c | 46 +++++++++-- drivers/iommu/arm/arm-smmu-v3/arm-smmu-v3.h | 1 + drivers/iommu/intel/iommu.c | 1 + drivers/iommu/iommufd/hw_pagetable.c | 5 +- drivers/iommu/iommufd/iommufd_private.h | 3 + drivers/iommu/iommufd/main.c | 14 ++++ drivers/iommu/iommufd/selftest.c | 1 + drivers/vfio/device_cdev.c | 3 + drivers/vfio/vfio.h | 2 + include/linux/iommu.h | 9 ++- include/linux/iommufd.h | 7 ++ include/linux/kvm_host.h | 18 +++++ virt/kvm/Kconfig | 3 + virt/kvm/kvm_main.c | 23 ++++++ 19 files changed, 225 insertions(+), 14 deletions(-) -- 2.33.0

Due to this appleir_input_configured() is never called, hidinput_connect() fails which results in the HID_CLAIMED_INPUT flag is not being set. However, it does not make appleir_probe() fail and lets the event callback to be called without the associated input device. Thus, add a check for the HID_CLAIMED_INPUT flag and leave the event hook early if the driver didn't claim any input_dev for some reason. Moreover, some other hid drivers accessing input_dev in their event callbacks do have similar checks, too. Found by Linux Verification Center (linuxtesting.org) with Syzkaller.

[PATCH OLK-6.6] LoongArch: Increase ARCH_DMA_MINALIGN up to 16
by Tengda Wu 18 Apr '25

18 Apr '25

From: Huacai Chen <chenhuacai(a)loongson.cn> stable inclusion from stable-6.6.87 commit 279ec25c2df49fba1cd9488f2ddd045d9cb2112e category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IC1QQA CVE: CVE-2025-22049 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 4103cfe9dcb88010ae4911d3ff417457d1b6a720 upstream. ARCH_DMA_MINALIGN is 1 by default, but some LoongArch-specific devices (such as APBDMA) require 16 bytes alignment. When the data buffer length is too small, the hardware may make an error writing cacheline. Thus, it is dangerous to allocate a small memory buffer for DMA. It's always safe to define ARCH_DMA_MINALIGN as L1_CACHE_BYTES but unnecessary (kmalloc() need small memory objects). Therefore, just increase it to 16.

[PATCH OLK-6.6 0/7] iommu/arm-smmu-v3: Use KVM VMID for s2 stage
by lishusen 18 Apr '25

18 Apr '25

On an ARM64 system with a SMMUv3 implementation that fully supports Broadcast TLB Maintenance(BTM) feature as part of the Distributed Virtual Memory(DVM) protocol, the CPU TLB invalidate instructions are received by SMMUv3. This is very useful when the SMMUv3 shares the page tables with the CPU(eg: Guest SVA use case). For this to work, the SMMUv3 must use the same VMID that is allocated by KVM to configure the nested stage 2(S2) translations.

[PATCH v2 OLK-6.6 0/3] soc cache: Add support for HiSilicon L3 cache
by Yushan Wang 17 Apr '25

17 Apr '25

driver inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/IC15TR ---------------------------------------------------------------------- This series adds support for HiSilicon SoC cache lockdown and cache maintenance operations. Cache lockdown feature prevents cache entries from being evicted from L3 cache. It can be enabled by calling mmap function to the file (`/dev/hisi_soc_cache_mgmt`). This feature is implemented in the driver hisi_soc_l3c. Cache maintenance feature, following Arm64's CHI spec[1], enables users to raise certain transactions to the memory residing in the cache. This can be achieved by calling ioctl function to the same file as above. This feature is implemented in the driver hisi_soc_hha. L3 cache and L3 cache PMU share the same memory resource, which makes one fails to probe while another is on board. Since both devices rely on distinct information exported by ACPI, their probing functions should be unrelated. Workaround the resource conflict check by replacing devm_ioremap_resource() to devm_ioremap() instead.

From: Saranya R <quic_sarar(a)quicinc.com> mainline inclusion from mainline-v6.14 commit 2eeb03ad9f42dfece63051be2400af487ddb96d2 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBZH8C CVE: CVE-2025-22014 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- When some client process A call pdr_add_lookup() to add the look up for the service and does schedule locator work, later a process B got a new server packet indicating locator is up and call pdr_locator_new_server() which eventually sets pdr->locator_init_complete to true which process A sees and takes list lock and queries domain list but it will timeout due to deadlock as the response will queued to the same qmi->wq and it is ordered workqueue and process B is not able to complete new server request work due to deadlock on list lock. Fix it by removing the unnecessary list iteration as the list iteration is already being done inside locator work, so avoid it here and just call schedule_work() here.

[PATCH OLK-6.6 v2] PCI: AER: fix deadlock in do_recovery

This patch does a pci_bus_walk and adds all the devices to a list. After unlocking (up_read) &pci_bus_sem, we go through the list and call err_handler of the devices with devic_lock() held. This way, we dont try to hold both locks at same time. v2: * Drop patch 1, 2 & 4. * Instead of locking 50+ devices, do get_device() and add them to a list.

[PATCH OLK-6.6 0/3] soc cache: Add support for HiSilicon L3 cache
by Yushan Wang 17 Apr '25

17 Apr '25

driver inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/IC15TR ---------------------------------------------------------------------- This series adds support for HiSilicon SoC cache lockdown and cache maintenance operations. Cache lockdown feature prevents cache entries from being evicted from L3 cache. It can be enabled by calling mmap function to the file (`/dev/hisi_soc_cache_mgmt`). This feature is implemented in the driver hisi_soc_l3c. Cache maintenance feature, following Arm64's CHI spec[1], enables users to raise certain transactions to the memory residing in the cache. This can be achieved by calling ioctl function to the same file as above. This feature is implemented in the driver hisi_soc_hha. L3 cache and L3 cache PMU share the same memory resource, which makes one fails to probe while another is on board. Since both devices rely on distinct information exported by ACPI, their probing functions should be unrelated. Workaround the resource conflict check by replacing devm_ioremap_resource() to devm_ioremap() instead.

[PATCH OLK-5.10] ftrace: Avoid potential division by zero in function_stat_show()
by Liu Chuang 17 Apr '25

17 Apr '25

From: Nikolay Kuratov <kniv(a)yandex-team.ru> stable inclusion from stable-v5.10.235 commit ca381f60a3bb7cfaa618d73ca411610bd7fc3149 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBY43C Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit a1a7eb89ca0b89dc1c326eeee2596f263291aca3 upstream.

[PATCH OLK-6.6 0/2] soc cache: Add support for HiSilicon L3 cache
by Yushan Wang 17 Apr '25

17 Apr '25

driver inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/IC15TR ---------------------------------------------------------------------- This series adds support for HiSilicon SoC cache lockdown and cache maintenance operations. Cache lockdown feature prevents cache entries from being evicted from L3 cache. It can be enabled by calling mmap function to the file (`/dev/hisi_soc_cache_mgmt`). This feature is implemented in the driver hisi_soc_l3c. Cache maintenance feature, following Arm64's CHI spec[1], enables users to raise certain transactions to the memory residing in the cache. This can be achieved by calling ioctl function to the same file as above. This feature is implemented in the driver hisi_soc_hha. L3 cache and L3 cache PMU share the same memory resource, which makes one fails to probe while another is on board. Since both devices rely on distinct information exported by ACPI, their probing functions should be unrelated. Workaround the resource conflict check by replacing devm_ioremap_resource() to devm_ioremap() instead.
