[PATCH openEuler-1.0-LTS 1/3] etmem: add original kernel swap enabled options

26 Jan '22

From: liubo <liubo254(a)huawei.com> euleros inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I4QVXW CVE: NA ------------------------------------------------- etmem, the memory vertical expansion technology, uses DRAM and high-performance storage new media to form multi-level memory storage. By grading the stored data, etmem migrates the classified cold storage data from the storage medium to the high-performance storage medium, so as to achieve the purpose of memory capacity expansion and memory cost reduction. When the memory expansion function etmem is running, the native swap function of the kernel needs to be disabled in certain scenarios to avoid the impact of kernel swap. This feature provides the preceding functions. The /sys/kernel/mm/swap/ directory provides the kernel_swap_enable sys interface to enable or disable the native swap function of the kernel. The default value of /sys/kernel/mm/swap/kernel_swap_enable is true, that is, kernel swap is enabled by default.

[PATCH OLK-5.10 v6 1/3] x86: pmem: move persistent memory(legacy) code into nvdimm
by Zhuling 21 Jan '22

21 Jan '22

hulk inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I4O31I Move x86's pmem.c into nvdimm, and rename X86_PMEM_LEGACY_DEVICE to PMEM_LEGACY_DEVICE, also add PMEM_LEGACY to control the built of nd_e820.o, then the code could be reused by other architectures. Note��this patch fixs the nd_e820.c build introduced by commit 2499317e408e ("arm64: Revert feature: Add memmap parameter and register pmem").

[PATCH openEuler-1.0-LTS] audit: bugfix for infinite loop when flush the hold queue
by Yang Yingliang 20 Jan '22

20 Jan '22

From: Cui GaoSheng <cuigaosheng1(a)huawei.com> hulk inclusion category: bugfix bugzilla: 186105, https://gitee.com/openeuler/kernel/issues/I4RGWS?from=project-issue CVE: NA ----------------------------------------------------------------- When we add "audit=1" to the cmdline, if we keep the audit_hold_queue non-empty, flush the hold queue will fall into an infinite loop. So we need to fix it by stoping flush the hold queue when netlink abnormal.

19 Jan '22

hulk inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I4O31I?from=project-issue CVE: NA ------------------------------ Register pmem in arm64: Use memmap(memmap=nn[KMG]!ss[KMG]) reserve memory for pmem to register persistent memory in arm64. when the kernel restart or update, the data in PMEM will not be lost and can be loaded faster. this is a general features. Currently, only one pmem can be registered and use. If you want use this features, you need do as follows: 1.Reserve memory: add memmap to reserve memory in grub.cfg memmap=nn[KMG]!ss[KMG] exp:memmap=100K!0x1a0000000. 2.Insmod nd_e820.ko: modprobe nd_e820. 3.Check pmem device in /dev exp: /dev/pmem0 driver/nvdimm/e820.c: The function of this file is scan "iomem_resource" and take advantage of nvdimm resource discovery mechanism by registering a resource named "Persistent Memory (legacy)", this function doesn't depend on architecture. We will push the feature to linux kernel community and discuss to modify the file name. because people have a mistaken notion that the e820.c is depend on x86.

[PATCH OLK-5.10] reboot: allow to specify reboot mode via sysfs
by Hongyu Li 18 Jan '22

18 Jan '22

From: Matteo Croce <mcroce(a)microsoft.com> mainline inclusion category: feature from mainline-v5.11 commit 2c622ed0eaa38b68d7440bedb8c6cdd138b5a860 bugzilla: https://gitee.com/openeuler/kernel/issues/I4BULZ CVE: NA -------------------------------- The kernel cmdline reboot= option offers some sort of control on how the reboot is issued. We don't always know in advance what type of reboot to perform. Sometimes a warm reboot is preferred to persist certain memory regions across the reboot. Others a cold one is needed to apply a future system update that makes a memory memory model change, like changing the base page size or resizing a persistent memory region. Or simply we want to enable reboot_force because we noticed that something bad happened. Add handles in sysfs to allow setting these reboot options, so they can be changed when the system is booted, other than at boot time. The handlers are under <sysfs>/kernel/reboot, can be read to get the current configuration and written to alter it. # cd /sys/kernel/reboot/ # grep . * cpu:0 force:0 mode:cold type:acpi # echo 2 >cpu # echo yes >force # echo soft >mode # echo bios >type # grep . * cpu:2 force:1 mode:soft type:bios Before setting anything, check for CAP_SYS_BOOT capability, so it's possible to allow an unpriviledged process to change these settings simply by relaxing the handles permissions, without opening them to the world.

[PATCH OLK-5.10] mm: introduce process_mrelease system call
by Wen Zhiwei 18 Jan '22

18 Jan '22

mainline inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I4FHN2?from=project-issue CVE: NA --------------------------- In modern systems it's not unusual to have a system component monitoring memory conditions of the system and tasked with keeping system memory pressure under control. One way to accomplish that is to kill non-essential processes to free up memory for more important ones. Examples of this are Facebook's OOM killer daemon called oomd and Android's low memory killer daemon called lmkd. For such system component it's important to be able to free memory quickly and efficiently. Unfortunately the time process takes to free up its memory after receiving a SIGKILL might vary based on the state of the process (uninterruptible sleep), size and OPP level of the core the process is running. A mechanism to free resources of the target process in a more predictable way would improve system's ability to control its memory pressure. Introduce process_mrelease system call that releases memory of a dying process from the context of the caller. This way the memory is freed in a more controllable way with CPU affinity and priority of the caller. The workload of freeing the memory will also be charged to the caller. The operation is allowed only on a dying process.
