[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 openEuler-1.0-LTS] net: bridge: clear bridge's private skb space on xmit

From: Nikolay Aleksandrov <nikolay(a)cumulusnetworks.com> mainline inclusion from mainline-v5.9-rc1 commit fd65e5a95d08389444e8591a20538b3edece0e15 category: bugfix bugzilla: 186114 CVE: NA -------------------------------- We need to clear all of the bridge private skb variables as they can be stale due to the packet being recirculated through the stack and then transmitted through the bridge device. Similar memset is already done on bridge's input. We've seen cases where proxyarp_replied was 1 on routed multicast packets transmitted through the bridge to ports with neigh suppress which were getting dropped. Same thing can in theory happen with the port isolation bit as well.

[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.
