by Peng Zhang 26 Apr '24

26 Apr '24

From: ZhangPeng <zhangpeng362(a)huawei.com> Update oedefconfig for the minimum set. Changes as follows: For arm64: CONFIG_PVPANIC from not set to y CONFIG_NET_SCH_FQ_CODEL from m to y CONFIG_VIRTIO_MEM from y to m CONFIG_ARM_SPE_PMU from y to m CONFIG_ARM_SMMU_V3_PMU from y to m CONFIG_DRM from y to m CONFIG_RTC_SYSTOHC from not set to y CONFIG_NTB from not set to m For x86: CONFIG_VIRTIO_MMIO from not set to m CONFIG_PCIE_EDR from not set to y CONFIG_IO_STRICT_DEVMEM from not set to y The previous commit updated config without make update_oedefconfig, so now make update_oedefconfig will move some lines.

[PATCH openEuler-1.0-LTS v2] x86/hyperv: Fix NULL deref in set_hv_tscchange_cb() if Hyper-V setup fails

From: Sean Christopherson <seanjc(a)google.com> stable inclusion from stable-v4.19.218 commit b20ec58f8a6f4fef32cc71480ddf824584e24743 bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9FNFO Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit daf972118c517b91f74ff1731417feb4270625a4 upstream.

[PATCH OLK-6.6 00/54] ext4: use iomap for regular file's buffered IO path and enable large foilo
by Zhang Yi 26 Apr '24

In min_key_size_set(): if (val > hdev->le_max_key_size || val < SMP_MIN_ENC_KEY_SIZE) return -EINVAL; hci_dev_lock(hdev); hdev->le_min_key_size = val; hci_dev_unlock(hdev); In max_key_size_set(): if (val > SMP_MAX_ENC_KEY_SIZE || val < hdev->le_min_key_size) return -EINVAL; hci_dev_lock(hdev); hdev->le_max_key_size = val; hci_dev_unlock(hdev); The atomicity violation occurs due to concurrent execution of set_min and set_max funcs.Consider a scenario where setmin writes a new, valid 'min' value, and concurrently, setmax writes a value that is greater than the old 'min' but smaller than the new 'min'. In this case, setmax might check against the old 'min' value (before acquiring the lock) but write its value after the 'min' has been updated by setmin. This leads to a situation where the 'max' value ends up being smaller than the 'min' value, which is an inconsistency. This possible bug is found by an experimental static analysis tool developed by our team, BassCheck[1]. This tool analyzes the locking APIs to extract function pairs that can be concurrently executed, and then analyzes the instructions in the paired functions to identify possible concurrency bugs including data races and atomicity violations. The above possible bug is reported when our tool analyzes the source code of Linux 5.17. To resolve this issue, it is suggested to encompass the validity checks within the locked sections in both set_min and set_max funcs. The modification ensures that the validation of 'val' against the current min/max values is atomic, thus maintaining the integrity of the settings. With this patch applied, our tool no longer reports the bug, with the kernel configuration allyesconfig for x86_64. Due to the lack of associated hardware, we cannot test the patch in runtime testing, and just verify it according to the code logic.

[PATCH OLK-6.6 0/4] A Solution to Re-enable hugetlb vmemmap optimize on ARM64
by Nanyong Sun 25 Apr '24

25 Apr '24

HVO was previously disabled on arm64 [1] due to the lack of necessary BBM(break-before-make) logic when changing page tables. This set of patches fix this by adding necessary BBM sequence when changing page table, and supporting vmemmap page fault handling to fixup kernel address translation fault if vmemmap is concurrently accessed. I have tested this patch set with concurrently accessing the vmemmap address when do BBM and can recover by vmemmap fault handler. Also tested under the config of 2/3/4 pgtable levels with 4K/64K page size and all works well. [1] commit 060a2c92d1b6 ("arm64: mm: hugetlb: Disable HUGETLB_PAGE_OPTIMIZE_VMEMMAP") Nanyong Sun (4): mm: HVO: introduce helper function to update and flush pgtable arm64: mm: HVO: support BBM of vmemmap pgtable safely arm64: mm: Re-enable OPTIMIZE_HUGETLB_VMEMMAP arm64: update openeuler_defconfig for HVO enable arch/arm64/Kconfig | 1 + arch/arm64/configs/openeuler_defconfig | 3 + arch/arm64/include/asm/esr.h | 4 ++ arch/arm64/include/asm/pgtable.h | 7 ++ arch/arm64/include/asm/tlbflush.h | 16 +++++ arch/arm64/mm/fault.c | 94 ++++++++++++++++++++++++-- arch/arm64/mm/mmu.c | 28 ++++++++ mm/hugetlb_vmemmap.c | 51 +++++++++++--- 8 files changed, 189 insertions(+), 15 deletions(-) -- 2.25.1

[PATCH OLK-6.6 0/3] A Solution to Re-enable hugetlb vmemmap optimize
by Nanyong Sun 24 Apr '24

24 Apr '24

HVO was previously disabled on arm64 [1] due to the lack of necessary BBM(break-before-make) logic when changing page tables. This set of patches fix this by adding necessary BBM sequence when changing page table, and supporting vmemmap page fault handling to fixup kernel address translation fault if vmemmap is concurrently accessed. I have tested this patch set with concurrently accessing the vmemmap address when do BBM and can recover by vmemmap fault handler. Also tested under the config of 2/3/4 pgtable levels with 4K/64K page size and all works well. [1] commit 060a2c92d1b6 ("arm64: mm: hugetlb: Disable HUGETLB_PAGE_OPTIMIZE_VMEMMAP") Nanyong Sun (3): mm: HVO: introduce helper function to update and flush pgtable arm64: mm: HVO: support BBM of vmemmap pgtable safely arm64: mm: Re-enable OPTIMIZE_HUGETLB_VMEMMAP arch/arm64/Kconfig | 1 + arch/arm64/include/asm/esr.h | 4 ++ arch/arm64/include/asm/pgtable.h | 7 +++ arch/arm64/include/asm/tlbflush.h | 16 ++++++ arch/arm64/mm/fault.c | 94 +++++++++++++++++++++++++++++-- arch/arm64/mm/mmu.c | 28 +++++++++ mm/hugetlb_vmemmap.c | 51 +++++++++++++---- 7 files changed, 186 insertions(+), 15 deletions(-) -- 2.25.1

[PATCH V6 OLK-6.6 0/2] Introduce BPF_READAHEAD option for optimizing read performance
by ZhaoLong Wang 24 Apr '24

24 Apr '24

This patch series introduces a new configuration option called BPF_READAHEAD, which is designed to optimize the read performance in Spark SQL scenarios using eBPF to implement a programmable kernel. The first patch adds the BPF_READAHEAD option to the kernel configuration, along with the necessary changes to the filesystem and memory management code to support this feature. The option is disabled by default and depends on CONFIG_TRACEPOINTS. The second patch enables the BPF_READAHEAD option in the openeuler_defconfig files for arm64, powerpc, riscv, and x86 architectures. This ensures that the feature is available on the supported architectures when needed. The BPF_READAHEAD option allows for fine-tuning the kernel's readahead behavior based on the application's read patterns, leading to improved read performance in specific scenarios like Spark SQL.

[PATCH OLK-5.10 0/4] Add hugetlb MADV_DONTNEED support
by Ze Zuo 24 Apr '24

24 Apr '24

MADV_DONTNEED is currently disabled for hugetlb mappings. This certainly makes sense in shared file mappings as the pagecache maintains a reference to the page and it will never be freed. However, it could be useful to unmap and free pages in private mappings.

[PATCH OLK-5.10] drm/mediatek: Fix a null pointer crash in mtk_drm_crtc_finish_page_flip

[PATCH V5 OLK-6.6] mm, fs: Add BPF_READAHEAD build option for bpf readhead
by ZhaoLong Wang 24 Apr '24

24 Apr '24

hulk inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I7Y9JD CVE: NA --------------------------- This patch introduces a new configuration option called BPF_READAHEAD, which is designed to optimize the read performance in Spark SQL scenarios using eBPF to implement a programmable kernel. The changes include: - Add CONFIG_BPF_READAHEAD to mm/Kconfig, which depends on CONFIG_TRACEPOINTS. - Add conditional compilation directives to fs/ext4/file.c, fs/read_write.c, fs/xfs/xfs_file.c, and include/linux/fs.h to include tracepoint-related headers and functions only when BPF_READAHEAD is enabled. - Miodify page_cache_sync_ra() in mm/readahead.c to disable forced readahead when BPF_READAHEAD is not enabled. V2: Explicitly set CONFIG_ in openeuler_defconfig. Do not add redundant macros to mm/readahead. V3: Place all macro isolation switches in the .h header file. V4: Change the macro name BPF_READAHEAD_OPTIMIZATION to BPF_READAHEAD V5: Correcting macro name replacement mistakes Signed-off-by: ZhaoLong Wang <wangzhaolong1(a)huawei.com> --- arch/arm64/configs/openeuler_defconfig | 1 + arch/powerpc/configs/openeuler_defconfig | 1 + arch/riscv/configs/openeuler_defconfig | 1 + arch/x86/configs/openeuler_defconfig | 1 + fs/read_write.c | 4 ++-- include/linux/fs.h | 18 +++++++++++++----- include/trace/events/fs.h | 6 ++++++ mm/Kconfig | 9 +++++++++ 8 files changed, 34 insertions(+), 7 deletions(-) diff --git a/arch/arm64/configs/openeuler_defconfig b/arch/arm64/configs/openeuler_defconfig index 9a6ef6175717..f3ab196f00ab 100644 --- a/arch/arm64/configs/openeuler_defconfig +++ b/arch/arm64/configs/openeuler_defconfig @@ -1192,6 +1192,7 @@ CONFIG_DYNAMIC_POOL=y CONFIG_ETMEM_SCAN=m CONFIG_ETMEM_SWAP=m CONFIG_ETMEM=y +# CONFIG_BPF_READAHEAD is not set # # Data Access Monitoring diff --git a/arch/powerpc/configs/openeuler_defconfig b/arch/powerpc/configs/openeuler_defconfig index 152b941da1d5..19754209e3c8 100644 --- a/arch/powerpc/configs/openeuler_defconfig +++ b/arch/powerpc/configs/openeuler_defconfig @@ -860,6 +860,7 @@ CONFIG_ARCH_HAS_HUGEPD=y CONFIG_USERFAULTFD=y # CONFIG_LRU_GEN is not set CONFIG_LOCK_MM_AND_FIND_VMA=y +# CONFIG_BPF_READAHEAD is not set # # Data Access Monitoring diff --git a/arch/riscv/configs/openeuler_defconfig b/arch/riscv/configs/openeuler_defconfig index cb132f4576da..90642dc106e2 100644 --- a/arch/riscv/configs/openeuler_defconfig +++ b/arch/riscv/configs/openeuler_defconfig @@ -825,6 +825,7 @@ CONFIG_ARCH_SUPPORTS_PER_VMA_LOCK=y CONFIG_PER_VMA_LOCK=y CONFIG_LOCK_MM_AND_FIND_VMA=y # CONFIG_PAGE_CACHE_LIMIT is not set +# CONFIG_BPF_READAHEAD is not set # # Data Access Monitoring diff --git a/arch/x86/configs/openeuler_defconfig b/arch/x86/configs/openeuler_defconfig index 1d20beb4bb6d..f49fc3ae7713 100644 --- a/arch/x86/configs/openeuler_defconfig +++ b/arch/x86/configs/openeuler_defconfig @@ -1179,6 +1179,7 @@ CONFIG_DYNAMIC_POOL=y CONFIG_ETMEM_SCAN=m CONFIG_ETMEM_SWAP=m CONFIG_ETMEM=y +# CONFIG_BPF_READAHEAD is not set # # Data Access Monitoring diff --git a/fs/read_write.c b/fs/read_write.c index 3d69fb284d10..dd5c90675f51 100644 --- a/fs/read_write.c +++ b/fs/read_write.c @@ -1721,7 +1721,7 @@ int generic_file_rw_checks(struct file *file_in, struct file *file_out) return 0; } -#ifdef CONFIG_TRACEPOINTS +#ifdef CONFIG_BPF_READAHEAD static void fs_file_read_ctx_init(struct fs_file_read_ctx *ctx, struct file *filp, loff_t pos) { @@ -1752,7 +1752,7 @@ void fs_file_read_update_args_by_trace(struct kiocb *iocb) filp->f_ctl_mode &= ~(ctx.clr_f_mode & FS_FILE_READ_MODE_MASK); } EXPORT_SYMBOL_GPL(fs_file_read_update_args_by_trace); -#endif EXPORT_TRACEPOINT_SYMBOL_GPL(fs_file_read); EXPORT_TRACEPOINT_SYMBOL_GPL(fs_file_release); +#endif diff --git a/include/linux/fs.h b/include/linux/fs.h index d74314a8fa94..55d2844f7fc6 100644 --- a/include/linux/fs.h +++ b/include/linux/fs.h @@ -43,7 +43,9 @@ #include <linux/cred.h> #include <linux/mnt_idmapping.h> #include <linux/slab.h> +#ifdef CONFIG_BPF_READAHEAD #include <linux/tracepoint-defs.h> +#endif #include <linux/kabi.h> #include <asm/byteorder.h> @@ -190,11 +192,16 @@ typedef int (dio_iodone_t)(struct kiocb *iocb, loff_t offset, /* File supports async nowait buffered writes */ #define FMODE_BUF_WASYNC ((__force fmode_t)0x80000000) +#ifdef CONFIG_BPF_READAHEAD /* File mode control flag, expect random access pattern */ #define FMODE_CTL_RANDOM ((__force fmode_t)0x1000) /* File mode control flag, will try to read head of the file into pagecache */ #define FMODE_CTL_WILLNEED ((__force fmode_t)0x400000) +#else +#define FMODE_CTL_RANDOM 0 +#define FMODE_CTL_WILLNEED 0 +#endif /* * Attribute flags.
