[PATCH OLK-6.6 00/21] Mitigate a vmap lock contention
by Peng Zhang 28 Mar '24

28 Mar '24

From: ZhangPeng <zhangpeng362(a)huawei.com> This patch set includes two patch sets: Mitigate a vmap lock contention and mm/vmalloc: lock contention optimization under multi-threading. In high-concurrency scenarios such as the "/test_vmalloc.sh run_test_mask=7 nr_threads=64" scenario, the performance is improved by more than 10x. The run time was reduced from 18m45.268s to 1m45.066s. Alexei Starovoitov (3): mm: Enforce VM_IOREMAP flag and range in ioremap_page_range. mm: Introduce VM_SPARSE kind and vm_area_[un]map_pages(). mm: Introduce vmap_page_range() to map pages in PCI address space Baoquan He (3): mm/vmalloc: fix the unchecked dereference warning in vread_iter() mm/vmalloc: remove vmap_area_list mm/vmalloc.c: optimize to reduce arguments of alloc_vmap_area() Kefeng Wang (1): mm: vmalloc: use old shrinker register Uladzislau Rezki (Sony) (13): mm: vmalloc: add va_alloc() helper mm: vmalloc: rename adjust_va_to_fit_type() function mm: vmalloc: move vmap_init_free_space() down in vmalloc.c mm: vmalloc: remove global vmap_area_root rb-tree mm: vmalloc: remove global purge_vmap_area_root rb-tree mm: vmalloc: offload free_vmap_area_lock lock mm: vmalloc: add a scan area of VA only once mm: vmalloc: support multiple nodes in vread_iter mm: vmalloc: support multiple nodes in vmallocinfo mm: vmalloc: set nr_nodes based on CPUs in a system mm: vmalloc: add a shrinker to drain vmap pools mm: vmalloc: improve description of vmap node layer mm: vmalloc: refactor vmalloc_dump_obj() function rulinhuang (1): mm/vmalloc: eliminated the lock contention from twice to once .../admin-guide/kdump/vmcoreinfo.rst | 8 +- arch/arm/mm/ioremap.c | 8 +- arch/arm64/kernel/crash_core.c | 1 - arch/loongarch/kernel/setup.c | 2 +- arch/mips/loongson64/init.c | 2 +- arch/powerpc/kernel/isa-bridge.c | 4 +- arch/riscv/kernel/crash_core.c | 1 - drivers/pci/pci.c | 4 +- include/linux/io.h | 7 + include/linux/vmalloc.h | 6 +- kernel/crash_core.c | 4 +- kernel/kallsyms_selftest.c | 1 - mm/nommu.c | 2 - mm/vmalloc.c | 1202 +++++++++++++---- 14 files changed, 936 insertions(+), 316 deletions(-) -- 2.25.1

[PATCH openEuler-1.0-LTS] i2c: i801: Don't generate an interrupt on bus reset
by Li Huafei 28 Mar '24

28 Mar '24

From: Jean Delvare <jdelvare(a)suse.de> stable inclusion from stable-v4.19.193 commit c70e1ba2e7e65255a0ce004f531dd90dada97a8c category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9BGWP CVE: CVE-2021-47153 --------------------------- commit e4d8716c3dcec47f1557024add24e1f3c09eb24b upstream. Now that the i2c-i801 driver supports interrupts, setting the KILL bit in a attempt to recover from a timed out transaction triggers an interrupt. Unfortunately, the interrupt handler (i801_isr) is not prepared for this situation and will try to process the interrupt as if it was signaling the end of a successful transaction. In the case of a block transaction, this can result in an out-of-range memory access. This condition was reproduced several times by syzbot: https://syzkaller.appspot.com/bug?extid=ed71512d469895b5b34e https://syzkaller.appspot.com/bug?extid=8c8dedc0ba9e03f6c79e https://syzkaller.appspot.com/bug?extid=c8ff0b6d6c73d81b610e https://syzkaller.appspot.com/bug?extid=33f6c360821c399d69eb https://syzkaller.appspot.com/bug?extid=be15dc0b1933f04b043a https://syzkaller.appspot.com/bug?extid=b4d3fd1dfd53e90afd79 So disable interrupts while trying to reset the bus. Interrupts will be enabled again for the following transaction.

[PATCH OLK-6.6] irqchip/gic-v3: Fix a system stall when using pseudo NMI with CONFIG_ARM64_NMI closed
by Jinjie Ruan 28 Mar '24

28 Mar '24

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I9CHAE -------------------------------- A system stall occurrs when using pseudo NMI with CONFIG_ARM64_NMI closed. If the hardware supports FEAT_NMI, the ALLINT bit in pstate may set or clear on exception trap whether the software enables it or not, so it is not safe to use it to check interrupts_enabled() or fast_interrupts_enabled() when FEAT_NMI not enabled in kernel, so recover it. After applying this patch, the system stall not happen again on hardware with FEAT_NMI feature.

[PATCH OLK-5.10 v4 0/2] Fix I/O high when memory almost met memcg limit
by Liu Shixin 28 Mar '24

28 Mar '24

Recently, when install package in a docker which almost reached its memory limit, the installer has no respond severely for more than 15 minutes. During this period, I/O stays high(~1G/s) and influence the whole machine. I've constructed a use case as follows: 1. create a docker: $ cat test.sh #!/bin/bash docker rm centos7 --force docker create --name centos7 --memory 4G --memory-swap 6G centos:7 /usr/sbin/init docker start centos7 sleep 1 docker cp ./alloc_page centos7:/ docker cp ./reproduce.sh centos7:/ docker exec -it centos7 /bin/bash 2. try reproduce the problem in docker: $ cat reproduce.sh #!/bin/bash while true; do flag=$(ps -ef | grep -v grep | grep alloc_page| wc -l) if [ "$flag" -eq 0 ]; then /alloc_page & fi sleep 30 start_time=$(date +%s) yum install -y expect > /dev/null 2>&1 end_time=$(date +%s) elapsed_time=$((end_time - start_time)) echo "$elapsed_time seconds" yum remove -y expect > /dev/null 2>&1 done $ cat alloc_page.c: #include <stdio.h> #include <stdlib.h> #include <unistd.h> #include <string.h> #define SIZE 1*1024*1024 //1M int main() { void *addr = NULL; int i; for (i = 0; i < 1024 * 6 - 50;i++) { addr = (void *)malloc(SIZE); if (!addr) return -1; memset(addr, 0, SIZE); } sleep(99999); return 0; } We found that this problem is caused by a lot ot meaningless read-ahead. Since the docker is almost met memory limit, the page will be reclaimed immediately after read-ahead and will read-ahead again immediately. The program is executed slowly and waste a lot of I/O resource. These patches aim to break the read-ahead in above scenario.

[PATCH OLK-6.6 0/6] Adding Huawei BMA driver
by Zheng Zengkai 28 Mar '24

28 Mar '24

From: Huajingjing <huajingjing1(a)huawei.com> This patch set contains 5 communication drivers for Huawei BMA software. The BMA software is a system management software. It supports the status monitoring, performance monitoring, and event monitoring of various components, including server CPUs, memory, hard disks, NICs, IB cards, PCIe cards, RAID controller cards, and optical modules. These 5 drivers are used to send/receive message through PCIe channel in different ways by BMA software.
