[PATCH OLK-5.10 0/5] cpumask: cleanup nr_cpu_ids vs nr_cpumask_bits mess
by Lu Jialin 13 Dec '23

13 Dec '23

From: Zheng Zucheng <zhengzucheng(a)huawei.com> cpumask subsystem uses nr_cpu_ids and nr_cpumask_bits interchangeably despite that the variables have different meaning and purpose. It makes some cpumask functions broken. This series cleans that mess and adds new config FORCE_NR_CPUS that allows to optimize cpumask subsystem if the number of CPUs is known at compile-time. After some testing I found build broken when SMP is on and NR_CPUS == 1. This is addressed in a new patch #1, and in the following patch #2 that now declares set_nr_cpu_ids in cpumask.h (was in smp.h). Yury Norov (5): smp: don't declare nr_cpu_ids if NR_CPUS == 1 smp: add set_nr_cpu_ids() lib/cpumask: delete misleading comment lib/cpumask: deprecate nr_cpumask_bits lib/cpumask: add FORCE_NR_CPUS config option arch/loongarch/kernel/setup.c | 2 +- arch/mips/kernel/setup.c | 2 +- arch/x86/kernel/smpboot.c | 4 ++-- arch/x86/xen/smp_pv.c | 2 +- include/linux/cpumask.h | 22 +++++++++++----------- kernel/smp.c | 6 ++++-- lib/Kconfig | 9 +++++++++ 7 files changed, 29 insertions(+), 18 deletions(-) -- 2.34.1

[PATCH OLK-5.10] locking/osq_lock: Avoid false sharing in optimistic_spin_node
by Zeng Heng 12 Dec '23

12 Dec '23

hulk inclusion category: performance bugzilla: https://gitee.com/openeuler/kernel/issues/I8MV01 -------------------------------- In the prologue of osq_lock(), it set `cpu` member of percpu struct optimistic_spin_node with the local cpu id, after that the value is never changed any more. Consequently, we can regard the `cpu` member as a constant variable. In the meanwhile, other members like next, prev and locked are frequently modified by osq_lock() and osq_unlock() which come from rwsem, mutex and so on. So here we can place padding and split them into different cache lines, so that avoid cache misses when a cpu is spinning to check previous node's cpu field by vcpu_is_preempted() in the following. Here provide the UnixBench full-core test result as below: Machine Intel(R) Xeon(R) Gold 6248 CPU, 40 cores, 80 threads Run the command of "./Run -c 80 -i 3" 10 times and take the average.

[PATCH OLK-5.10] KVM: arm64: Translate logic cluster id to physical cluster id when updating lsudvmbm
by chenxiang 12 Dec '23

12 Dec '23

From: Xiang Chen <chenxiang66(a)hisilicon.com> driver inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8HY1B ---------------------------------------------------------------- For dvmbm feature, MN requires physical cluster id while it is filled with logic cluster id right now. In some situations which physical cluster id is not equal to logic cluster id such as in PG boards, it will cause issues when enabling dvmbm. To avoid the issue, translate logic cluster id to physical cluster id when updating lsudvmbm.

[PATCH OLK-6.6 v4 0/7] support userswap feature
by Peng Zhang 12 Dec '23

12 Dec '23

From: ZhangPeng <zhangpeng362(a)huawei.com> This patch series support userswap feature including registration, unregistration, swap-out and swap-in. Userswap feature depends on CONFIG_USERSWAP and can be enabled by cmdline enable_userswap. We tested the concurrent scenario of multi-threaded page fault and multi-threaded swap-in in the uswap demo;and the remapping in the swap-out phase and the copy-free function in the swap-in phase were ok. During the test, related debugging functions including CONFIG_DEBUG_VM, lockdep, slub debug, kasan and kmemleak are enabled. ChangeLog: v3->v4: - define UFFDIO_REGISTER_MODE_USWAP ((__u64)1<<10) rather than ((__u64)1<<3) v2->v3: - update patch 7 commit v1->v2: - enable CONFIG_USERSWAP for openeuler_defconfig ZhangPeng (7): mm/userswap: add VM_USWAP and SWP_USERSWAP_ENTRY mm/userswap: add enable_userswap boot option mm/userswap: introduce MREMAP_USWAP_SET_PTE mm/userswap: support userswap via userfaultfd mm/userswap: introduce UFFDIO_COPY_MODE_DIRECT_MAP mm/userswap: provide cpu info in userfault msg mm/userswap: openeuler_defconfig: enable userswap arch/arm64/configs/openeuler_defconfig | 1 + arch/x86/configs/openeuler_defconfig | 1 + fs/proc/task_mmu.c | 3 + fs/userfaultfd.c | 43 +- include/linux/mm.h | 8 + include/linux/swap.h | 14 +- include/linux/swapops.h | 16 + include/linux/userfaultfd_k.h | 5 + include/linux/userswap.h | 60 +++ include/trace/events/mmflags.h | 7 + include/uapi/linux/mman.h | 1 + include/uapi/linux/userfaultfd.h | 3 + mm/Kconfig | 10 + mm/Makefile | 1 + mm/memory.c | 8 + mm/mremap.c | 8 +- mm/userfaultfd.c | 12 + mm/userswap.c | 552 +++++++++++++++++++++++++ 18 files changed, 747 insertions(+), 6 deletions(-) create mode 100644 include/linux/userswap.h create mode 100644 mm/userswap.c -- 2.25.1

[PATCH v2 OLK-5.10] iommu/arm-smmu-v3: Add a SYNC command to avoid broken page table prefetch
by Zhang Zekun 11 Dec '23

hulk inclusion category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I8MVBZ CVE: NA ----------------------------------------------- On Hisilicon LINXICORE9100 cores, SMMU pagetable prefetch features may prefetch and use a invalid PTE even the PTE is valid at that time. This will cause the device trigger fake pagefaults. If the SMMU works in terminate mode, transactions which occur fake pagefaults will be aborted, and could result in unexpected errors. To fix this problem, we need to add a SYNC command after smmu has map a iova, then smmu will always try to get the newest PTE.

[PATCH OLK-6.6 v3] config: Open CONFIG_AARCH32_EL0 and keep CONFIG_ARM64_ILP32 closed
by Jinjie Ruan 11 Dec '23

11 Dec '23

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8JVJ3 CVE: NA ------------------------------------------------------------------------- No one currently uses IPL32, keep it closed to simplify the code logic of TASK_SIZE_MAX, thereby improving benchmark performance. For example, all test items of libMicro can be improved by 4.89% on average. Since commit dbece8b041f3 ("arm64: rename COMPAT to AARCH32_EL0"), CONFIG_COMPAT has been renamed to CONFIG_AARCH32_EL0, so open CONFIG_AARCH32_EL0 as what CONFIG_COMPAT used to be. And as commit 880fd21c0a46 ("arm64: set 32-bit compatible TASK_SIZE_MAX to fix U32 libc_write_01 error") said, not set CONFIG_COMPAT_TASK_SIZE by default.

[PATCH V2 OLK-5.10 0/6] Make the rcache depot scale better
by Zhang Zekun 10 Dec '23

10 Dec '23

Recently we have meet a problem when running FIO test. In our kunpeng server with 320 cores, about 80% cpus comes to- 100% usage, and soft lockup appears in the kernel message, which shows it stuck in __alloc_and_insert_iova_range(). Both the call trace and high cpu occupy rate implys that the iova_rcache behaves poorly to alloc iovas. A similar problem has been addressed in early months this year, the solution is just to enlarge the MAX_GLOBAL_MAGS to 128, but it requires to growth with the cpu cores, and it is hard to set a accurate val for a specific machine. So, it is better to use solutions from the linux community, use a list to replace the array of iova_rcache->depot. It will push iova_magazine to depot list when the local cpu_rcache is full, and use schedul_delayed_work() to free it after 100ms. The minimum length of the depot list is the num of online_cpus(). The performance of this patch shows good. This patch set use a lot of timers to record the iova_magazine, and the delay of timers in system may increase when undering heavy work load, but it should not cause problem as timers itself allows a inaccurate delay for a range. v2: - change a comment in patch 5/6, no code change. We need to merge "iommu/iova: change IOVA_MAG_SIZE to 127 to save memory" first to resolve a compile error: error: static assertion failed: "!(sizeof(struct iova_magazine) & (sizeof(struct iova_magazine) - 1))" Feng Tang (1): iommu/iova: change IOVA_MAG_SIZE to 127 to save memory Zhang Zekun (5): Revert "iommu/iova: move IOVA_MAX_GLOBAL_MAGS outside of IOMMU_SUPPORT" Revert "config: enable set the max iova mag size to 128" Revert "iommu/iova: increase the iova_rcache depot max size to 128" iommu/iova: Make the rcache depot scale better iommu/iova: Manage the depot list size arch/arm64/configs/openeuler_defconfig | 1 - drivers/iommu/Kconfig | 10 ---- drivers/iommu/iova.c | 80 +++++++++++++++++++------- include/linux/iova.h | 7 ++- 4 files changed, 64 insertions(+), 34 deletions(-) -- 2.17.1

[PATCH OLK-5.10] iommu/arm-smmu-v3: Add a SYNC command to avoid broken page table prefetch
by Zhang Zekun 10 Dec '23

10 Dec '23

hulk inclusion category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I8MVBZ CVE: NA ----------------------------------------------- On Hisilicon LINXICORE9100 cores, SMMU pagetable prefetch features may prefetch and use a invalid PTE even the PTE is valid at that time. This will cause the device trigger fake pagefaults. If the SMMU works in terminate mode, transactions which occur fake pagefaults will be aborted, and could result in unexpected errors. To fix this problem, we need to add a SYNC command after smmu has map a iova, then smmu will always try to get the newest PTE.

[PATCH OLK-5.10] locking/osq_lock: Avoid false sharing in optimistic_spin_node
by Zeng Heng 08 Dec '23

08 Dec '23

hulk inclusion category: performance bugzilla: https://gitee.com/openeuler/kernel/issues/I8MV01 -------------------------------- In the prologue of osq_lock(), it set `cpu` member of percpu struct optimistic_spin_node with the local cpu id, after that the value is never changed any more. Consequently, we can regard the `cpu` member as a constant variable. In the meanwhile, other members like next, prev and locked are frequently modified by osq_lock() and osq_unlock() which come from rwsem, mutex and so on. So here we can place padding and locate them at different cache lines, so that avoid cache misses when access optimistic_spin_node.cpu field by other CPUs from the node list. Here provide the UnixBench full-core test result as below: Machine Intel(R) Xeon(R) Gold 6248 CPU, 40 cores, 80 threads Run the command of "./Run -c 80 -i 3" 10 times and take the average.

[PATCH OLK-6.6 v3 00/19] Add sharepool support v3
by Wang Wensheng 08 Dec '23

08 Dec '23

This patch series migrates share pool features from OLK-5.10 to OLK-6.6. We don't want to do this work patch by patch since there are hundreds of patches in OLK-5.10 including bugfix and small features generation. Instead we just take the final version and split it into a few small patches, each of which contains one feature at the final version. The share pool features is a big feature, it is mainly used to share user virtual memory for different processes in the same group. It could be used by this steps: Process A create a new group which is owned by process A. Process A add process B to the group. Process A add process C to the same group. Process B alloc a new memory VA, and write something in it. The VA was send to the process C by IPC, then process C got it. The process C access the VA and got the data directly. The process A could add more processes in the group to share the memory. Fix the memory by use the free function or exit the group. The new features is enabled both by CONFIG_SHARE_POOL and the enable_ascend_share_pool bootarg, it would not affect anything if disabled. v1->v2: Delete some unused code. v2->v3: Rename several function.

[PATCH OLK-5.10] module: Expose module_init_layout_section()
by Zhao Wenhui 08 Dec '23

08 Dec '23

From: James Morse <james.morse(a)arm.com> stable inclusion from stable-v5.10.194 commit ecd62c85120dc74b07c5ccd1532de121e81a4dba category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I83LMD Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 2abcc4b5a64a65a2d2287ba0be5c2871c1552416 upstream. module_init_layout_section() choses whether the core module loader considers a section as init or not. This affects the placement of the exit section when module unloading is disabled. This code will never run, so it can be free()d once the module has been initialised. arm and arm64 need to count the number of PLTs they need before applying relocations based on the section name. The init PLTs are stored separately so they can be free()d. arm and arm64 both use within_module_init() to decide which list of PLTs to use when applying the relocation. Because within_module_init()'s behaviour changes when module unloading is disabled, both architecture would need to take this into account when counting the PLTs. Today neither architecture does this, meaning when module unloading is disabled there are insufficient PLTs in the init section to load some modules, resulting in warnings: | WARNING: CPU: 2 PID: 51 at arch/arm64/kernel/module-plts.c:99 module_emit_plt_entry+0x184/0x1cc | Modules linked in: crct10dif_common | CPU: 2 PID: 51 Comm: modprobe Not tainted 6.5.0-rc4-yocto-standard-dirty #15208 | Hardware name: QEMU KVM Virtual Machine, BIOS 0.0.0 02/06/2015 | pstate: 20400005 (nzCv daif +PAN -UAO -TCO -DIT -SSBS BTYPE=--) | pc : module_emit_plt_entry+0x184/0x1cc | lr : module_emit_plt_entry+0x94/0x1cc | sp : ffffffc0803bba60 [...] | Call trace: | module_emit_plt_entry+0x184/0x1cc | apply_relocate_add+0x2bc/0x8e4 | load_module+0xe34/0x1bd4 | init_module_from_file+0x84/0xc0 | __arm64_sys_finit_module+0x1b8/0x27c | invoke_syscall.constprop.0+0x5c/0x104 | do_el0_svc+0x58/0x160 | el0_svc+0x38/0x110 | el0t_64_sync_handler+0xc0/0xc4 | el0t_64_sync+0x190/0x194 Instead of duplicating module_init_layout_section()s logic, expose it.

[PATCH OLK-6.6 v2 00/19] Add sharepool support
by Wang Wensheng 08 Dec '23

08 Dec '23

This patch series migrates share pool features from OLK-5.10 to OLK-6.6. We don't want to do this work patch by patch since there are hundreds of patches in OLK-5.10 including bugfix and small features generation. Instead we just take the final version and split it into a few small patches, each of which contains one feature at the final version. The share pool features is a big feature, it is mainly used to share user virtual memory for different processes in the same group. It could be used by this steps: Process A create a new group which is owned by process A. Process A add process B to the group. Process A add process C to the same group. Process B alloc a new memory VA, and write something in it. The VA was send to the process C by IPC, then process C got it. The process C access the VA and got the data directly. The process A could add more processes in the group to share the memory. Fix the memory by use the free function or exit the group. The new features is enabled both by CONFIG_SHARE_POOL and the enable_ascend_share_pool bootarg, it would not affect anything if disabled. v1->v2: Delete some unused code. Wang Wensheng (19): mm/hugetlb: Introduce hugetlb_insert_hugepage_pte[_by_pa] mm/vmalloc: Extend vmalloc usage about hugepage mm: Extend mmap assocated functions to accept mm_struct mm/sharepool: Add base framework for share_pool mm/sharepool: Add sp_area management code mm/sharepool: Reserve the va space for share_pool mm/sharepool: Implement mg_sp_make_share_u2k() mm/sharepool: Implement mg_sp_unshare_kva mm/sharepool: Implement mg_sp_walk_page_range() mm/sharepool: Implement mg_sp_free() mm/sharepool: Implement mg_sp_alloc() mm/sharepool: Implement mg_sp_make_share_k2u() mm/sharepool: Implement mg_sp_group_add_task() mm/sharepool: Implement mg_sp_group_id_by_pid() mm/sharepool: Implement mg_sp_id_of_current() mm/sharepool: Implement mg_sp_config_dvpp_range() mm/sharepool: Add proc interfaces to show sp info mm/sharepool: support fork() and exit() to handle the mm mm/sharepool: Protect the va reserved for sharepool include/linux/hugetlb.h | 32 + include/linux/mempolicy.h | 11 + include/linux/mm.h | 17 + include/linux/mm_types.h | 6 + include/linux/share_pool.h | 267 +++ include/linux/vmalloc.h | 18 + kernel/fork.c | 3 + mm/Kconfig | 34 + mm/Makefile | 1 + mm/gup.c | 23 +- mm/hugetlb.c | 78 + mm/mempolicy.c | 12 +- mm/mmap.c | 50 +- mm/mremap.c | 4 + mm/share_pool.c | 3448 ++++++++++++++++++++++++++++++++++++ mm/util.c | 4 + mm/vmalloc.c | 205 ++- 17 files changed, 4192 insertions(+), 21 deletions(-) create mode 100644 include/linux/share_pool.h create mode 100644 mm/share_pool.c -- 2.17.1

[PATCH OLK-6.6 0/2] arm64: errata: add option to disable cache readunique prefetch on HIP08
by Yang Yingliang 08 Dec '23

08 Dec '23

Random performance decreases appear on cases of Hackbench which test pipe or socket communication among multi-threads on Hisi HIP08 SoC. Cache sharing which caused by the change of the data layout and the cache readunique prefetch mechanism both lead to this problem. Readunique mechanism which may caused by store operation will invalid cachelines on other cores during data fetching stage which can cause cacheline invalidation happens frequently in a sharing data access situation. Disable cache readunique prefetch can trackle this problem. Test cases are like: for i in 20;do echo "--------pipe thread num=$i----------" for j in $(seq 1 10);do ./hackbench -pipe $i thread 1000 done done We disable readunique prefetch only in el2 for in el1 disabling readunique prefetch may cause panic due to lack of related priority which often be set in BIOS. Introduce CONFIG_HISILICON_ERRATUM_HIP08_RU_PREFETCH and disable RU prefetch using boot cmdline 'readunique_prefetch=off'.

[PATCH OLK-6.6 0/7]arm64: add machine check safe support
by Tong Tiangen 08 Dec '23

08 Dec '23

With the increase of memory capacity and density, the probability of memory error also increases. The increasing size and density of server RAM in data centers and clouds have shown increased uncorrectable memory errors. Currently, the kernel has mechanism to recover from hardware memory errors. This patchset provides a new recovery mechanism. For arm64, the hardware memory error handling in do_sea(), which is divided into two cases: 1. If the user state consumed the memory errors, the solution is to kill the user process and isolate the error page. 2. If the kernel state consumed the memory errors, the solution is to panic. For case 2, Undifferentiated panic may not be the optimal choice, as it can be handled better. In some scenarios, we can avoid panic, such as uaccess, if the uaccess fails due to memory error, only the user process will be affected, killing the user process and isolating the user page with hardware memory errors is a better choice. Tong Tiangen (7): uaccess: add generic fallback version of copy_mc_to_user() arm64: add support for machine check error safe arm64: add uaccess to machine check safe mm/hwpoison: return -EFAULT when copy fail in copy_mc_[user]_highpage() arm64: support copy_mc_[user]_highpage() arm64: introduce copy_mc_to_kernel() implementation arm64: add machine check safe sysctl interface Documentation/admin-guide/sysctl/kernel.rst | 14 ++ arch/arm64/Kconfig | 1 + arch/arm64/include/asm/asm-extable.h | 15 ++ arch/arm64/include/asm/assembler.h | 4 + arch/arm64/include/asm/extable.h | 1 + arch/arm64/include/asm/mte.h | 5 + arch/arm64/include/asm/page.h | 10 + arch/arm64/include/asm/string.h | 5 + arch/arm64/include/asm/uaccess.h | 21 ++ arch/arm64/lib/Makefile | 4 +- arch/arm64/lib/copy_from_user.S | 10 +- arch/arm64/lib/copy_mc_page.S | 89 +++++++ arch/arm64/lib/copy_to_user.S | 10 +- arch/arm64/lib/memcpy_mc.S | 257 ++++++++++++++++++++ arch/arm64/lib/mte.S | 27 ++ arch/arm64/mm/copypage.c | 66 ++++- arch/arm64/mm/extable.c | 21 +- arch/arm64/mm/fault.c | 58 ++++- arch/powerpc/include/asm/uaccess.h | 1 + arch/x86/include/asm/uaccess.h | 1 + include/linux/highmem.h | 16 +- include/linux/uaccess.h | 9 + mm/kasan/shadow.c | 12 + mm/khugepaged.c | 4 +- 24 files changed, 635 insertions(+), 26 deletions(-) create mode 100644 arch/arm64/lib/copy_mc_page.S create mode 100644 arch/arm64/lib/memcpy_mc.S -- 2.25.1

[PATCH OLK-6.6 v2 00/19] Add sharepool support
by Wang Wensheng 07 Dec '23

07 Dec '23

This patch series migrates share pool features from OLK-5.10 to OLK-6.6. We don't want to do this work patch by patch since there are hundreds of patches in OLK-5.10 including bugfix and small features generation. Instead we just take the final version and split it into a few small patches, each of which contains one feature at the final version. The share pool features is a big feature, it is mainly used to share user virtual memory for different processes in the same group. It could be used by this steps: Process A create a new group which is owned by process A. Process A add process B to the group. Process A add process C to the same group. Process B alloc a new memory VA, and write something in it. The VA was send to the process C by IPC, then process C got it. The process C access the VA and got the data directly. The process A could add more processes in the group to share the memory. Fix the memory by use the free function or exit the group. The new features is enabled both by CONFIG_SHARE_POOL and the enable_ascend_share_pool bootarg, it would not affect anything if disabled. v1->v2: Delete some unused code. Wang Wensheng (19): mm/hugetlb: Introduce hugetlb_insert_hugepage_pte[_by_pa] mm/vmalloc: Extend vmalloc usage about hugepage mm: Extend mmap assocated functions to accept mm_struct mm/sharepool: Add base framework for share_pool mm/sharepool: Add sp_area management code mm/sharepool: Reserve the va space for share_pool mm/sharepool: Implement mg_sp_make_share_u2k() mm/sharepool: Implement mg_sp_unshare_kva mm/sharepool: Implement mg_sp_walk_page_range() mm/sharepool: Implement mg_sp_free() mm/sharepool: Implement mg_sp_alloc() mm/sharepool: Implement mg_sp_make_share_k2u() mm/sharepool: Implement mg_sp_group_add_task() mm/sharepool: Implement mg_sp_group_id_by_pid() mm/sharepool: Implement mg_sp_id_of_current() mm/sharepool: Implement mg_sp_config_dvpp_range() mm/sharepool: Add proc interfaces to show sp info mm/sharepool: support fork() and exit() to handle the mm mm/sharepool: Protect the va reserved for sharepool include/linux/hugetlb.h | 32 + include/linux/mempolicy.h | 11 + include/linux/mm.h | 17 + include/linux/mm_types.h | 6 + include/linux/share_pool.h | 267 +++ include/linux/vmalloc.h | 18 + kernel/fork.c | 3 + mm/Kconfig | 34 + mm/Makefile | 1 + mm/gup.c | 23 +- mm/hugetlb.c | 78 + mm/mempolicy.c | 12 +- mm/mmap.c | 50 +- mm/mremap.c | 4 + mm/share_pool.c | 3448 ++++++++++++++++++++++++++++++++++++ mm/util.c | 4 + mm/vmalloc.c | 205 ++- 17 files changed, 4192 insertions(+), 21 deletions(-) create mode 100644 include/linux/share_pool.h create mode 100644 mm/share_pool.c -- 2.17.1

If we set a hardware breakpoint on a memory address, and at the same time there is a kprobe event that also goes to get the memory of that address, then when kprobe triggers, it will go to read the memory and trigger hardware breakpoint monitoring, at this time, because kprobe handles debug exceptions earlier than hardware breakpoints, it will cause kprobe to incorrectly consider this exception as a kprobe trigger. Kprobe will change the status from KPROBE_HIT_ACTIVE to KPROBE_HIT_SS or KPROBE_REENTER before single-step execution, so if the current status is KPROBE_HIT_ACTIVE, its not a debug exception triggered by kprobe.

[PATCH OLK-5.10] iommu/arm-smmu-v3: disable stall for quiet_cd

From: Wenkai Lin <linwenkai6(a)hisilicon.com> hulk inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I8MCHF CVE: NA Reference: https://lore.kernel.org/all/20231206005517.46005-1-zhangfei.gao@linaro.org/… -------------------------------- In the stall model, invalid transactions were expected to be stalled and aborted by the IOPF handler. However, when killing a test case with a huge amount of data, the accelerator streamline can not stop until all data is consumed even if the page fault handler reports errors. As a result, the kill may take a long time, about 10 seconds with numerous iopf interrupts. So disable stall for quiet_cd in the non-force stall model, since force stall model (STALL_MODEL==0b10) requires CD.S must be 1.

[PATCH OLK-6.6 0/2] arm64: errata: add option to disable cache readunique prefetch on HIP08
by Yang Yingliang 07 Dec '23

07 Dec '23

Random performance decreases appear on cases of Hackbench which test pipe or socket communication among multi-threads on Hisi HIP08 SoC. Cache sharing which caused by the change of the data layout and the cache readunique prefetch mechanism both lead to this problem. Readunique mechanism which may caused by store operation will invalid cachelines on other cores during data fetching stage which can cause cacheline invalidation happens frequently in a sharing data access situation. Disable cache readunique prefetch can trackle this problem. Test cases are like: for i in 20;do echo "--------pipe thread num=$i----------" for j in $(seq 1 10);do ./hackbench -pipe $i thread 1000 done done We disable readunique prefetch only in el2 for in el1 disabling readunique prefetch may cause panic due to lack of related priority which often be set in BIOS. Introduce CONFIG_HISILICON_ERRATUM_HIP08_RU_PREFETCH and disable RU prefetch using boot cmdline 'readunique_prefetch=off'.

[PATCH OLK-5.10 0/6] Make the rcache depot scale better
by Zhang Zekun 07 Dec '23

07 Dec '23

Recently we have meet a problem when running FIO test. In our kunpeng server with 320 cores, about 80% cpus comes to- 100% usage, and soft lockup appears in the kernel message, which shows it stuck in __alloc_and_insert_iova_range(). Both the call trace and high cpu occupy rate implys that the iova_rcache behaves poorly to alloc iovas. A similar problem has been addressed in early months this year, the solution is just to enlarge the MAX_GLOBAL_MAGS to 128, but it requires to growth with the cpu cores, and it is hard to set a accurate val for a specific machine. So, it is better to use solutions from the linux community, use a list to replace the array of iova_rcache->depot. It will push iova_magazine to depot list when the local cpu_rcache is full, and use schedul_delayed_work() to free it after 100ms. The minimum length of the depot list is the num of online_cpus(). The performance of this patch shows good. This patch set use a lot of timers to record the iova_magazine, and the delay of timers in system may increase when undering heavy work load, but it should not cause problem as timers itself allows a inaccurate delay for a range. We need to merge "iommu/iova: change IOVA_MAG_SIZE to 127 to save memory" first to resolve a compile error: error: static assertion failed: "!(sizeof(struct iova_magazine) & (sizeof(struct iova_magazine) - 1))" Feng Tang (1): iommu/iova: change IOVA_MAG_SIZE to 127 to save memory Zhang Zekun (5): Revert "iommu/iova: move IOVA_MAX_GLOBAL_MAGS outside of IOMMU_SUPPORT" Revert "config: enable set the max iova mag size to 128" Revert "iommu/iova: increase the iova_rcache depot max size to 128" iommu/iova: Make the rcache depot scale better iommu/iova: Manage the depot list size arch/arm64/configs/openeuler_defconfig | 1 - drivers/iommu/Kconfig | 10 ---- drivers/iommu/iova.c | 79 +++++++++++++++++++------- include/linux/iova.h | 7 ++- 4 files changed, 63 insertions(+), 34 deletions(-) -- 2.17.1

[PATCH openEuler-1.0-LTS] workqueue: Override implicit ordered attribute in workqueue_apply_unbound_cpumask()
by Yu Liao 07 Dec '23

From: Waiman Long <longman(a)redhat.com> stable inclusion from stable-v4.19.299 commit 55d1e6231a0b98ffcc5eacdae995fa7bd74bf6a0 bugzilla: https://gitee.com/openeuler/kernel/issues/I8MCB5 CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit ca10d851b9ad0338c19e8e3089e24d565ebfffd7 ] Commit 5c0338c68706 ("workqueue: restore WQ_UNBOUND/max_active==1 to be ordered") enabled implicit ordered attribute to be added to WQ_UNBOUND workqueues with max_active of 1. This prevented the changing of attributes to these workqueues leading to fix commit 0a94efb5acbb ("workqueue: implicit ordered attribute should be overridable"). However, workqueue_apply_unbound_cpumask() was not updated at that time. So sysfs changes to wq_unbound_cpumask has no effect on WQ_UNBOUND workqueues with implicit ordered attribute. Since not all WQ_UNBOUND workqueues are visible on sysfs, we are not able to make all the necessary cpumask changes even if we iterates all the workqueue cpumasks in sysfs and changing them one by one. Fix this problem by applying the corresponding change made to apply_workqueue_attrs_locked() in the fix commit to workqueue_apply_unbound_cpumask().

However, when killing a test case with a huge amount of data, the accelerator streamline can not stop until all data is consumed even if the page fault handler reports errors. As a result, the kill may take a long time, about 10 seconds with numerous iopf interrupts. So disable stall for quiet_cd in the non-force stall model, since force stall model (STALL_MODEL==0b10) requires CD.S must be 1.

From: Ma Wupeng <mawupeng1(a)huawei.com> During page eject, machine check safe is enhanced as follow: During soft offline page, page is copied to new page in kernel. If the origin page has UCE, there will lead to kernel panic. In order to solve this problem, use machine check safe to catch this error which can be achieved by using copy_mc_to_kernel to replace copy_page. Signal SIGBUS will be send to user task if this UCE is consumed by this situation to avoid kernel panic.

This has been confirmed to break NFS mounts running in UDP mode and has the potential to break other systems. This patch: 1) Creates a new function called __sock_sendmsg() with same logic as the old sock_sendmsg() function. 2) Replaces calls to sock_sendmsg() made by __sys_sendto() and __sys_sendmsg() with __sock_sendmsg() to avoid an unnecessary copy, as these system calls are already protected. 3) Modifies sock_sendmsg() so that it makes a copy of msg_name if present before passing it down the stack to insulate callers from changes to the send address.

[PATCH openEuler-1.0-LTS] fs: don't audit the capability check in simple_xattr_list()
by Zizhi Wo 04 Dec '23

04 Dec '23

From: Ondrej Mosnacek <omosnace(a)redhat.com> mainline inclusion from mainline-v6.2-rc1 commit e7eda157c4071cd1e69f4b1687b0fbe1ae5e6f46 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8LQI5?from=project-issue CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- The check being unconditional may lead to unwanted denials reported by LSMs when a process has the capability granted by DAC, but denied by an LSM. In the case of SELinux such denials are a problem, since they can't be effectively filtered out via the policy and when not silenced, they produce noise that may hide a true problem or an attack. Checking for the capability only if any trusted xattr is actually present wouldn't really address the issue, since calling listxattr(2) on such node on its own doesn't indicate an explicit attempt to see the trusted xattrs. Additionally, it could potentially leak the presence of trusted xattrs to an unprivileged user if they can check for the denials (e.g. through dmesg). Therefore, it's best (and simplest) to keep the check unconditional and instead use ns_capable_noaudit() that will silence any associated LSM denials.

[PATCH OLK-6.6 00/19] Add sharepool support
by Wang Wensheng 04 Dec '23

04 Dec '23

This patch series migrates share pool features from OLK-5.10 to OLK-6.6. We don't want to do this work patch by patch since there are hundreds of patches in OLK-5.10 including bugfix and small features generation. Instead we just take the final version and split it into a few small patches, each of which contains one feature at the final version. The share pool features is a big feature, it is mainly used to share user virtual memory for different processes in the same group. It could be used by this steps: Process A create a new group which is owned by process A. Process A add process B to the group. Process A add process C to the same group. Process B alloc a new memory VA, and write something in it. The VA was send to the process C by IPC, then process C got it. The process C access the VA and got the data directly. The process A could add more processes in the group to share the memory. Fix the memory by use the free function or exit the group. The new features is enabled both by CONFIG_SHARE_POOL and the enable_ascend_share_pool bootarg, it would not affect anything if disabled.

This has been confirmed to break NFS mounts running in UDP mode and has the potential to break other systems. This patch: 1) Creates a new function called __sock_sendmsg() with same logic as the old sock_sendmsg() function. 2) Replaces calls to sock_sendmsg() made by __sys_sendto() and __sys_sendmsg() with __sock_sendmsg() to avoid an unnecessary copy, as these system calls are already protected. 3) Modifies sock_sendmsg() so that it makes a copy of msg_name if present before passing it down the stack to insulate callers from changes to the send address.

[PATCH OLK-6.6 0/2] arm64: errata: add option to disable cache readunique prefetch on HIP08
by Yang Yingliang 04 Dec '23

04 Dec '23

Random performance decreases appear on cases of Hackbench which test pipe or socket communication among multi-threads on Hisi HIP08 SoC. Cache sharing which caused by the change of the data layout and the cache readunique prefetch mechanism both lead to this problem. Readunique mechanism which may caused by store operation will invalid cachelines on other cores during data fetching stage which can cause cacheline invalidation happens frequently in a sharing data access situation. Disable cache readunique prefetch can trackle this problem. Test cases are like: for i in 20;do echo "--------pipe thread num=$i----------" for j in $(seq 1 10);do ./hackbench -pipe $i thread 1000 done done We disable readunique prefetch only in el2 for in el1 disabling readunique prefetch may cause panic due to lack of related priority which often be set in BIOS. Introduce CONFIG_HISILICON_ERRATUM_HIP08_RU_PREFETCH and disable RU prefetch using boot cmdline 'readunique_prefetch=off'.

[PATCH openEuler-1.0-LTS] mm: don't let userspace spam allocations warnings

From: Daniel Vetter <daniel.vetter(a)ffwll.ch> mainline inclusion from mainline-v5.0-rc8 commit 6c8fcc096be9d02f478c508052a41a4430506ab3 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8LMVO CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- memdump_user usually gets fed unchecked userspace input. Blasting a full backtrace into dmesg every time is a bit excessive - I'm not sure on the kernel rule in general, but at least in drm we're trying not to let unpriviledge userspace spam the logs freely. Definitely not entire warning backtraces. It also means more filtering for our CI, because our testsuite exercises these corner cases and so hits these a lot.

[PATCH OLK-6.6] mm: Add sysctl to clear free list pages
by Yu Liao 04 Dec '23

04 Dec '23

hulk inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I4SK3S CVE: NA -------------------------------- This patch add sysctl to clear pages in free lists of each NUMA node. For each NUMA node, clear each page in the free list, these work is scheduled on a random CPU of the NUMA node. When kasan is enabled and the pages are free, the shadow memory will be filled with 0xFF, writing these free pages will cause UAF, so just disable KASAN for clear freelist. In the case of large memory, the clear freelist will hold zone lock for a long time. As a result, the process may be blocked unless clear freelist thread exit, and causing the system to be reset by the watchdog. Provide a mechanism to stop clear freelist threads when elapsed time exceeds cfp_timeout, which can be set by module_param().

[PATCH OLK-6.6] arm64: errata: add option to disable cache readunique prefetch on HIP08

04 Dec '23

From: Kai Shen <shenkai8(a)huawei.com> hulk inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I3ZFV2 CVE: NA ----------------------------------------------------------- Random performance decreases appear on cases of Hackbench which test pipe or socket communication among multi-threads on Hisi HIP08 SoC. Cache sharing which caused by the change of the data layout and the cache readunique prefetch mechanism both lead to this problem. Readunique mechanism which may caused by store operation will invalid cachelines on other cores during data fetching stage which can cause cacheline invalidation happens frequently in a sharing data access situation. Disable cache readunique prefetch can trackle this problem. Test cases are like: for i in 20;do echo "--------pipe thread num=$i----------" for j in $(seq 1 10);do ./hackbench -pipe $i thread 1000 done done We disable readunique prefetch only in el2 for in el1 disabling readunique prefetch may cause panic due to lack of related priority which often be set in BIOS.

[openEuler-1.0-LTS] net: prevent rewrite of msg_name in sock_sendmsg()
by Lu Wei 04 Dec '23

04 Dec '23

From: Jordan Rife <jrife(a)google.com> stable inclusion from stable-v4.19.297 commit 3d62f2577c7414e5b94e4baad6eb621165960f30 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I8EZY4 CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 86a7e0b69bd5b812e48a20c66c2161744f3caa16 ] Callers of sock_sendmsg(), and similarly kernel_sendmsg(), in kernel space may observe their value of msg_name change in cases where BPF sendmsg hooks rewrite the send address. This has been confirmed to break NFS mounts running in UDP mode and has the potential to break other systems. This patch: 1) Creates a new function called __sock_sendmsg() with same logic as the old sock_sendmsg() function. 2) Replaces calls to sock_sendmsg() made by __sys_sendto() and __sys_sendmsg() with __sock_sendmsg() to avoid an unnecessary copy, as these system calls are already protected. 3) Modifies sock_sendmsg() so that it makes a copy of msg_name if present before passing it down the stack to insulate callers from changes to the send address.

[PATCH V4 OLK-5.10] vhost-vdpa: add reset state params to indicate reset level
by Jiang Dongxu 04 Dec '23

04 Dec '23

From: jiangdongxu <jiangdongxu1(a)huawei.com> virt inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I86ITO ---------------------------------------------------------------------- When vdpa hardware is used, some hardware initialization may be required. Currently, qemu connects to vdpa devices through the vhost framework. Since qemu opens the vhost device, the vdpa device cannot sense the action of qemu opening, which may cause the hardware status to be incorrect. Add the interface parameter state to the vdpa reset interface, which respectively identifies the reset when the device is turned on/off and the virtio reset issued by the virtual machine.
