by Peng Zhang 29 Mar '24

29 Mar '24

From: ZhangPeng <zhangpeng362(a)huawei.com> maillist inclusion category: performance bugzilla: https://gitee.com/openeuler/kernel/issues/I9CKXN CVE: NA Reference: https://lore.kernel.org/all/20240327090835.3232629-1-zhangpeng362@huawei.co… -------------------------------- When vma->vm_userfaultfd_ctx.ctx is NULL, vma->vm_flags should have cleared __VM_UFFD_FLAGS. Therefore, there is no need to down_write or clear the flag, which will affect fork performance. Fix this by returning early if octx is NULL in dup_userfaultfd(). By applying this patch we can get a 1.3% performance improvement for lmbench fork_prot. Results are as follows: base early return Process fork+exit: 419.1106 413.4804 Link: https://lkml.kernel.org/r/20240327090835.3232629-1-zhangpeng362@huawei.com Signed-off-by: ZhangPeng <zhangpeng362(a)huawei.com> Reviewed-by: Peter Xu <peterx(a)redhat.com> Cc: Axel Rasmussen <axelrasmussen(a)google.com> Cc: David Hildenbrand <david(a)redhat.com> Cc: Kefeng Wang <wangkefeng.wang(a)huawei.com> Cc: Liam R.

[PATCH OLK-6.6 v3 00/18] Mitigate a vmap lock contention
by Peng Zhang 29 Mar '24

29 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. Changelog: v2->v3: - Fix commit format warning v1->v2: - Remove 2 maillist inclusion patches - Merge patch 21 to resolve the conflict in patch 16 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 (2): mm/vmalloc: fix the unchecked dereference warning in vread_iter() mm/vmalloc: remove vmap_area_list 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 .../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 | 1156 +++++++++++++---- 14 files changed, 914 insertions(+), 292 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.

[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.

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.
