From: Luo Gengkun <luogengkun(a)huaweicloud.com> stable inclusion from stable-v6.6.81 commit f0c3971405cef6892844016aa710121a02da3a23 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBUX7R Reference: https://git.kernel.org/stable/c/f0c3971405cef6892844016aa710121a02da3a23 -------------------------------- [ Upstream commit 2016066c66192a99d9e0ebf433789c490a6785a2 ] Syskaller triggers a warning due to prev_epc->pmu != next_epc->pmu in perf_event_swap_task_ctx_data(). vmcore shows that two lists have the same perf_event_pmu_context, but not in the same order. The problem is that the order of pmu_ctx_list for the parent is impacted by the time when an event/PMU is added. While the order for a child is impacted by the event order in the pinned_groups and flexible_groups. So the order of pmu_ctx_list in the parent and child may be different. To fix this problem, insert the perf_event_pmu_context to its proper place after iteration of the pmu_ctx_list. The follow testcase can trigger above warning: # perf record -e cycles --call-graph lbr -- taskset -c 3 ./a.out & # perf stat -e cpu-clock,cs -p xxx // xxx is the pid of a.out test.c void main() { int count = 0; pid_t pid; printf("%d running\n", getpid()); sleep(30); printf("running\n"); pid = fork(); if (pid == -1) { printf("fork error\n"); return; } if (pid == 0) { while (1) { count++; } } else { while (1) { count++; } } } The testcase first opens an LBR event, so it will allocate task_ctx_data, and then open tracepoint and software events, so the parent context will have 3 different perf_event_pmu_contexts. On inheritance, child ctx will insert the perf_event_pmu_context in another order and the warning will trigger.

[PATCH openEuler-1.0-LTS] mm/hugetlb: fix surplus pages in dissolve_free_huge_page()
by Jinjiang Tu 21 Mar '25

21 Mar '25

mainline inclusion from mainline-v6.14-rc6 commit cb402bbdabcaa5a765068c5b8673bbfc1c264242 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBV73U CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… ------------------------------------------- In dissolve_free_huge_page(), free huge pages are dissolved without adjusting surplus count. However, free huge pages may be accounted as surplus pages, and will lead to wrong surplus count. I reproduce this issue on qemu. The steps are: 1) Node1 is memory-less at first. Hot-add memory to node1 by executing the two commands in qemu monitor: object_add memory-backend-ram,id=mem1,size=1G device_add pc-dimm,id=dimm1,memdev=mem1,node=1 2) online one memory block of Node1 with： echo online_movable > /sys/devices/system/node/node1/memoryX/state 3) create 64 huge pages for node1 4) run a program to reserve (don't consume) all the huge pages 5) echo 0 > nr_huge_pages for node1. After this step, free huge pages in Node1 are surplus. 6) create 80 huge pages for node0 7) offline memory of node1, The memory range to offline contains the free surplus huge pages created in step3) ~ step5) echo offline > /sys/devices/system/node/node1/memoryX/state 8) kill the program in step 4) The result: Node0 Node1 total 80 0 free 80 0 surplus 0 61 To fix it, adjust surplus when destroying huge pages if the node has surplus pages in dissolve_free_hugetlb_folio(). The result with this patch: Node0 Node1 total 80 0 free 80 0 surplus 0 0 Link: https://lkml.kernel.org/r/20250304132106.2872754-1-tujinjiang@huawei.com Fixes: c8721bbbdd36 ("mm: memory-hotplug: enable memory hotplug to handle hugepage") Signed-off-by: Jinjiang Tu <tujinjiang(a)huawei.com> Acked-by: David Hildenbrand <david(a)redhat.com> Acked-by: Oscar Salvador <osalvador(a)suse.de> Cc: Jinjiang Tu <tujinjiang(a)huawei.com> Cc: Kefeng Wang <wangkefeng.wang(a)huawei.com> Cc: Muchun Song <muchun.song(a)linux.dev> Cc: Nanyong Sun <sunnanyong(a)huawei.com> Signed-off-by: Andrew Morton <akpm(a)linux-foundation.org> Conflicts: mm/hugetlb.c [Context conflicts, and HVO isn't introduced, so don't need to handle HVO err case.] Signed-off-by: Jinjiang Tu <tujinjiang(a)huawei.com> --- mm/hugetlb.c | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) diff --git a/mm/hugetlb.c b/mm/hugetlb.c index 69dd1e096a48..ac6f18afdf76 100644 --- a/mm/hugetlb.c +++ b/mm/hugetlb.c @@ -1823,6 +1823,7 @@ int dissolve_free_huge_page(struct page *page) if (!page_count(page)) { struct page *head = compound_head(page); struct hstate *h = page_hstate(head); + bool adjust_surplus = false; if (h->free_huge_pages - h->resv_huge_pages == 0) goto out; @@ -1853,7 +1854,9 @@ int dissolve_free_huge_page(struct page *page) SetPageHWPoison(page); ClearPageHWPoison(head); } - remove_hugetlb_page(h, head, false); + if (h->surplus_huge_pages_node[page_to_nid(head)]) + adjust_surplus = true; + remove_hugetlb_page(h, head, adjust_surplus); h->max_huge_pages--; spin_unlock_irq(&hugetlb_lock); update_and_free_page(h, head); -- 2.43.0
