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
by Chen Jun 07 Dec '23

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()

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.
