[PATCH OLK-6.6] perf/core: Order the PMU list to fix warning about unordered pmu_ctx_list
by Luo Gengkun 21 Mar '25

21 Mar '25

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

[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: 190517 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

[PATCH openEuler-1.0-LTS] scsi: lpfc: Fix null pointer dereference after failing to issue FLOGI and PLOGI
by Guo Mengqi 19 Mar '25

19 Mar '25

From: James Smart <jsmart2021(a)gmail.com> mainline inclusion from mainline-v5.19-rc1 commit 577a942df3de2666f6947bdd3a5c9e8d30073424 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBP6SH CVE: CVE-2022-49535 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- [ Upstream commit 577a942df3de2666f6947bdd3a5c9e8d30073424 ] If lpfc_issue_els_flogi() fails and returns non-zero status, the node reference count is decremented to trigger the release of the nodelist structure. However, if there is a prior registration or dev-loss-evt work pending, the node may be released prematurely. When dev-loss-evt completes, the released node is referenced causing a use-after-free null pointer dereference. Similarly, when processing non-zero ELS PLOGI completion status in lpfc_cmpl_els_plogi(), the ndlp flags are checked for a transport registration before triggering node removal. If dev-loss-evt work is pending, the node may be released prematurely and a subsequent call to lpfc_dev_loss_tmo_handler() results in a use after free ndlp dereference. Add test for pending dev-loss before decrementing the node reference count for FLOGI, PLOGI, PRLI, and ADISC handling.

From: Andrii Nakryiko <andrii(a)kernel.org> stable inclusion from stable-v6.6.80 commit fc01ba097319ae2033f118da3075bd783f4a08e9 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBSW0M CVE: CVE-2025-21853 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 98671a0fd1f14e4a518ee06b19037c20014900eb ] For all BPF maps we ensure that VM_MAYWRITE is cleared when memory-mapping BPF map contents as initially read-only VMA. This is because in some cases BPF verifier relies on the underlying data to not be modified afterwards by user space, so once something is mapped read-only, it shouldn't be re-mmap'ed as read-write. As such, it's not necessary to check VM_MAYWRITE in bpf_map_mmap() and map->ops->map_mmap() callbacks: VM_WRITE should be consistently set for read-write mappings, and if VM_WRITE is not set, there is no way for user space to upgrade read-only mapping to read-write one. This patch cleans up this VM_WRITE vs VM_MAYWRITE handling within bpf_map_mmap(), which is an entry point for any BPF map mmap()-ing logic. We also drop unnecessary sanitization of VM_MAYWRITE in BPF ringbuf's map_mmap() callback implementation, as it is already performed by common code in bpf_map_mmap(). Note, though, that in bpf_map_mmap_{open,close}() callbacks we can't drop VM_MAYWRITE use, because it's possible (and is outside of subsystem's control) to have initially read-write memory mapping, which is subsequently dropped to read-only by user space through mprotect(). In such case, from BPF verifier POV it's read-write data throughout the lifetime of BPF map, and is counted as "active writer". But its VMAs will start out as VM_WRITE|VM_MAYWRITE, then mprotect() can change it to just VM_MAYWRITE (and no VM_WRITE), so when its finally munmap()'ed and bpf_map_mmap_close() is called, vm_flags will be just VM_MAYWRITE, but we still need to decrement active writer count with bpf_map_write_active_dec() as it's still considered to be a read-write mapping by the rest of BPF subsystem. Similar reasoning applies to bpf_map_mmap_open(), which is called whenever mmap(), munmap(), and/or mprotect() forces mm subsystem to split original VMA into multiple discontiguous VMAs. Memory-mapping handling is a bit tricky, yes.

[PATCH OLK-6.6] media: uvcvideo: Fix crash during unbind if gpio unit is in use
by Zhang Kunbo 17 Mar '25

From: Ricardo Ribalda <ribalda(a)chromium.org> stable inclusion from stable-v6.6.78 commit 0b5e0445bc8384c18bd35cb9fe87f6258c6271d9 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBRED4 CVE: CVE-2024-58079 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit a9ea1a3d88b7947ce8cadb2afceee7a54872bbc5 upstream. We used the wrong device for the device managed functions. We used the usb device, when we should be using the interface device. If we unbind the driver from the usb interface, the cleanup functions are never called. In our case, the IRQ is never disabled. If an IRQ is triggered, it will try to access memory sections that are already free, causing an OOPS. We cannot use the function devm_request_threaded_irq here. The devm_* clean functions may be called after the main structure is released by uvc_delete. Luckily this bug has small impact, as it is only affected by devices with gpio units and the user has to unbind the device, a disconnect will not trigger this error.

[PATCH openEuler-1.0-LTS] ath9k_htc: fix uninit value bugs
by He Yujie 15 Mar '25

15 Mar '25

From: Pavel Skripkin <paskripkin(a)gmail.com> stable inclusion from stable-v4.19.238 commit ee4222052a76559c20e821bc3519cefb58b6d3e9 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBP2I0 CVE: CVE-2022-49235 Reference: https://web.git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit… -------------------------------- [ Upstream commit d1e0df1c57bd30871dd1c855742a7c346dbca853 ] Syzbot reported 2 KMSAN bugs in ath9k. All of them are caused by missing field initialization. In htc_connect_service() svc_meta_len and pad are not initialized. Based on code it looks like in current skb there is no service data, so simply initialize svc_meta_len to 0. htc_issue_send() does not initialize htc_frame_hdr::control array. Based on firmware code, it will initialize it by itself, so simply zero whole array to make KMSAN happy Fail logs: BUG: KMSAN: kernel-usb-infoleak in usb_submit_urb+0x6c1/0x2aa0 drivers/usb/core/urb.c:430 usb_submit_urb+0x6c1/0x2aa0 drivers/usb/core/urb.c:430 hif_usb_send_regout drivers/net/wireless/ath/ath9k/hif_usb.c:127 [inline] hif_usb_send+0x5f0/0x16f0 drivers/net/wireless/ath/ath9k/hif_usb.c:479 htc_issue_send drivers/net/wireless/ath/ath9k/htc_hst.c:34 [inline] htc_connect_service+0x143e/0x1960 drivers/net/wireless/ath/ath9k/htc_hst.c:275 ...

All of them are caused by missing field initialization. In htc_connect_service() svc_meta_len and pad are not initialized. Based on code it looks like in current skb there is no service data, so simply initialize svc_meta_len to 0. htc_issue_send() does not initialize htc_frame_hdr::control array.

Therefore, the two locks can be concurrent. ctrl_cdev_ioctl contains two operations: ubi_attach and ubi_detach. ubi_detach is bug-free because it uses reference counting to prevent concurrency. However, uif_init and uif_close in ubi_attach may race with ubi_cdev_ioctl. uif_init will race with ubi_cdev_ioctl as in the following stack. cpu1 cpu2 cpu3 _______________________|________________________|______________________ ctrl_cdev_ioctl ubi_attach_mtd_dev uif_init ubi_cdev_ioctl ubi_create_volume cdev_device_add ubi_add_volume // sysfs exist kill_volumes ubi_cdev_ioctl ubi_remove_volume cdev_device_del // first free ubi_free_volume cdev_del // double free cdev_device_del And uif_close will race with ubi_cdev_ioctl as in the following stack. cpu1 cpu2 cpu3 _______________________|________________________|______________________ ctrl_cdev_ioctl ubi_attach_mtd_dev uif_init ubi_cdev_ioctl ubi_create_volume cdev_device_add ubi_debugfs_init_dev //error goto out_uif; uif_close kill_volumes ubi_cdev_ioctl ubi_remove_volume cdev_device_del // first free ubi_free_volume // double free The cause of this problem is that commit 714fb87e8bc0 make device "available" before it becomes accessible via sysfs. Therefore, we roll back the modification. We will fix the race condition between ubi device creation and udev by removing ubi_get_device in vol_attribute_show and dev_attribute_show.This avoids accessing uninitialized ubi_devices[ubi_num]. ubi_get_device is used to prevent devices from being deleted during sysfs execution. However, now kernfs ensures that devices will not be deleted before all reference counting are released. The key process is shown in the following stack. device_del device_remove_attrs device_remove_groups sysfs_remove_groups sysfs_remove_group remove_files kernfs_remove_by_name kernfs_remove_by_name_ns __kernfs_remove kernfs_drain Fixes: 714fb87e8bc0 ("ubi: Fix race condition between ubi device creation and udev") Reported-by: Hulk Robot <hulkci(a)huawei.com> Signed-off-by: Baokun Li <libaokun1(a)huawei.com> Signed-off-by: Richard Weinberger <richard(a)nod.at> Conflicts: drivers/mtd/ubi/build.c [Not merged: fc55dacf7fea and its prerequisite patches.] Signed-off-by: Wang Zhaolong <wangzhaolong1(a)huawei.com> --- drivers/mtd/ubi/build.c | 9 +-------- drivers/mtd/ubi/vmt.c | 8 +------- 2 files changed, 2 insertions(+), 15 deletions(-) diff --git a/drivers/mtd/ubi/build.c b/drivers/mtd/ubi/build.c index 93cce95287ba..d15c6a64f7cd 100644 --- a/drivers/mtd/ubi/build.c +++ b/drivers/mtd/ubi/build.c @@ -361,13 +361,10 @@ static ssize_t dev_attribute_show(struct device *dev, * * Remember, 'struct ubi_device' is freed in the release function, so * we still can use 'ubi->ubi_num'. */ ubi = container_of(dev, struct ubi_device, dev); - ubi = ubi_get_device(ubi->ubi_num); - if (!ubi) - return -ENODEV; if (attr == &dev_eraseblock_size) ret = sprintf(buf, "%d\n", ubi->leb_size); else if (attr == &dev_avail_eraseblocks) ret = sprintf(buf, "%d\n", ubi->avail_pebs); @@ -392,11 +389,10 @@ static ssize_t dev_attribute_show(struct device *dev, else if (attr == &dev_ro_mode) ret = sprintf(buf, "%d\n", ubi->ro_mode); else ret = -EINVAL; - ubi_put_device(ubi); return ret; } static struct attribute *ubi_dev_attrs[] = { &dev_eraseblock_size.attr, @@ -974,13 +970,10 @@ int ubi_attach_mtd_dev(struct mtd_info *mtd, int ubi_num, err = autoresize(ubi, ubi->autoresize_vol_id); if (err) goto out_detach; } - /* Make device "available" before it becomes accessible via sysfs */ - ubi_devices[ubi_num] = ubi; - err = uif_init(ubi); if (err) goto out_detach; err = ubi_debugfs_init_dev(ubi); @@ -1021,19 +1014,19 @@ int ubi_attach_mtd_dev(struct mtd_info *mtd, int ubi_num, spin_lock(&ubi->wl_lock); ubi->thread_enabled = 1; wake_up_process(ubi->bgt_thread); spin_unlock(&ubi->wl_lock); + ubi_devices[ubi_num] = ubi; ubi_notify_all(ubi, UBI_VOLUME_ADDED, NULL); return ubi_num; out_debugfs: ubi_debugfs_exit_dev(ubi); out_uif: uif_close(ubi); out_detach: - ubi_devices[ubi_num] = NULL; ubi_wl_close(ubi); ubi_free_internal_volumes(ubi); vfree(ubi->vtbl); out_free: vfree(ubi->peb_buf); diff --git a/drivers/mtd/ubi/vmt.c b/drivers/mtd/ubi/vmt.c index 729588b94e41..d0c6b66b7450 100644 --- a/drivers/mtd/ubi/vmt.c +++ b/drivers/mtd/ubi/vmt.c @@ -67,20 +67,15 @@ static struct device_attribute attr_vol_upd_marker = static ssize_t vol_attribute_show(struct device *dev, struct device_attribute *attr, char *buf) { int ret; struct ubi_volume *vol = container_of(dev, struct ubi_volume, dev); - struct ubi_device *ubi; - - ubi = ubi_get_device(vol->ubi->ubi_num); - if (!ubi) - return -ENODEV; + struct ubi_device *ubi = vol->ubi; spin_lock(&ubi->volumes_lock); if (!ubi->volumes[vol->vol_id]) { spin_unlock(&ubi->volumes_lock); - ubi_put_device(ubi); return -ENODEV; } /* Take a reference to prevent volume removal */ vol->ref_count += 1; spin_unlock(&ubi->volumes_lock); @@ -114,11 +109,10 @@ static ssize_t vol_attribute_show(struct device *dev, /* We've done the operation, drop volume and UBI device references */ spin_lock(&ubi->volumes_lock); vol->ref_count -= 1; ubi_assert(vol->ref_count >= 0); spin_unlock(&ubi->volumes_lock); - ubi_put_device(ubi); return ret; } static struct attribute *volume_dev_attrs[] = { &attr_vol_reserved_ebs.attr, -- 2.34.3

[PATCH openEuler-1.0-LTS] wifi: mac80211: fix use-after-free in chanctx code

From: Johannes Berg <johannes.berg(a)intel.com> stable inclusion from stable-v4.19.247 commit 9f1e5cc85ad77e52f54049a94db0407445ae2a34 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBP3RV CVE: CVE-2022-49416 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 2965c4cdf7ad9ce0796fac5e57debb9519ea721e upstream. In ieee80211_vif_use_reserved_context(), when we have an old context and the new context's replace_state is set to IEEE80211_CHANCTX_REPLACE_NONE, we free the old context in ieee80211_vif_use_reserved_reassign(). Therefore, we cannot check the old_ctx anymore, so we should set it to NULL after this point. However, since the new_ctx replace state is clearly not IEEE80211_CHANCTX_REPLACES_OTHER, we're not going to do anything else in this function and can just return to avoid accessing the freed old_ctx.

[PATCH openEuler-1.0-LTS] dlm: fix plock invalid read
by Xia Fukun 14 Mar '25

14 Mar '25

From: Alexander Aring <aahringo(a)redhat.com> stable inclusion from stable-v4.19.247 commit 5a1765adf9855cf0f6d3f7e0eb4b78ca66f70dee category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBP3TG CVE: CVE-2022-49407 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 42252d0d2aa9b94d168241710a761588b3959019 upstream. This patch fixes an invalid read showed by KASAN. A unlock will allocate a "struct plock_op" and a followed send_op() will append it to a global send_list data structure. In some cases a followed dev_read() moves it to recv_list and dev_write() will cast it to "struct plock_xop" and access fields which are only available in those structures. At this point an invalid read happens by accessing those fields. To fix this issue the "callback" field is moved to "struct plock_op" to indicate that a cast to "plock_xop" is allowed and does the additional "plock_xop" handling if set. Example of the KASAN output which showed the invalid read: [ 2064.296453] ================================================================== [ 2064.304852] BUG: KASAN: slab-out-of-bounds in

[PATCH openEuler-1.0-LTS] mm: fix unexpected zeroed page mapping with zram swap
by Liu Shixin 14 Mar '25

14 Mar '25

From: Minchan Kim <minchan(a)kernel.org> stable inclusion from stable-v4.19.242 commit f86d55cf616199404c05f5b0c5c41b17351baa02 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBP28G CVE: CVE-2022-49052 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit e914d8f00391520ecc4495dd0ca0124538ab7119 upstream. Two processes under CLONE_VM cloning, user process can be corrupted by seeing zeroed page unexpectedly. CPU A CPU B do_swap_page do_swap_page SWP_SYNCHRONOUS_IO path SWP_SYNCHRONOUS_IO path swap_readpage valid data swap_slot_free_notify delete zram entry swap_readpage zeroed(invalid) data pte_lock map the *zero data* to userspace pte_unlock pte_lock if (!pte_same) goto out_nomap; pte_unlock return and next refault will read zeroed data The swap_slot_free_notify is bogus for CLONE_VM case since it doesn't increase the refcount of swap slot at copy_mm so it couldn't catch up whether it's safe or not to discard data from backing device. In the case, only the lock it could rely on to synchronize swap slot freeing is page table lock. Thus, this patch gets rid of the swap_slot_free_notify function. With this patch, CPU A will see correct data. CPU A CPU B do_swap_page do_swap_page SWP_SYNCHRONOUS_IO path SWP_SYNCHRONOUS_IO path swap_readpage original data pte_lock map the original data swap_free swap_range_free bd_disk->fops->swap_slot_free_notify swap_readpage read zeroed data pte_unlock pte_lock if (!pte_same) goto out_nomap; pte_unlock return on next refault will see mapped data by CPU B The concern of the patch would increase memory consumption since it could keep wasted memory with compressed form in zram as well as uncompressed form in address space. However, most of cases of zram uses no readahead and do_swap_page is followed by swap_free so it will free the compressed form from in zram quickly.

[PATCH OLK-5.10] PCI: rcar-ep: Fix incorrect variable used when calling devm_request_mem_region()

From: King Dix <kingdix10(a)qq.com> mainline inclusion from mainline-v6.14-rc1 commit 2d2da5a4c1b4509f6f7e5a8db015cd420144beb4 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBPLK2 CVE: CVE-2025-21804 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- The rcar_pcie_parse_outbound_ranges() uses the devm_request_mem_region() macro to request a needed resource. A string variable that lives on the stack is then used to store a dynamically computed resource name, which is then passed on as one of the macro arguments. This can lead to undefined behavior. Depending on the current contents of the memory, the manifestations of errors may vary. One possible output may be as follows: $ cat /proc/iomem 30000000-37ffffff : 38000000-3fffffff : Sometimes, garbage may appear after the colon. In very rare cases, if no NULL-terminator is found in memory, the system might crash because the string iterator will overrun which can lead to access of unmapped memory above the stack. Thus, fix this by replacing outbound_name with the name of the previously requested resource.

[PATCH OLK-6.6] hrtimers: Force migrate away hrtimers queued after CPUHP_AP_HRTIMERS_DYING
by Xiongfeng Wang 13 Mar '25

13 Mar '25

From: Frederic Weisbecker <frederic(a)kernel.org> mainline inclusion from mainline-v6.14-rc2 commit 53dac345395c0d2493cbc2f4c85fe38aef5b63f5 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBPLI0 CVE: CVE-2025-21816 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- hrtimers are migrated away from the dying CPU to any online target at the CPUHP_AP_HRTIMERS_DYING stage in order not to delay bandwidth timers handling tasks involved in the CPU hotplug forward progress. However wakeups can still be performed by the outgoing CPU after CPUHP_AP_HRTIMERS_DYING. Those can result again in bandwidth timers being armed. Depending on several considerations (crystal ball power management based election, earliest timer already enqueued, timer migration enabled or not), the target may eventually be the current CPU even if offline. If that happens, the timer is eventually ignored. The most notable example is RCU which had to deal with each and every of those wake-ups by deferring them to an online CPU, along with related workarounds: _ e787644caf76 (rcu: Defer RCU kthreads wakeup when CPU is dying) _ 9139f93209d1 (rcu/nocb: Fix RT throttling hrtimer armed from offline CPU) _ f7345ccc62a4 (rcu/nocb: Fix rcuog wake-up from offline softirq) The problem isn't confined to RCU though as the stop machine kthread (which runs CPUHP_AP_HRTIMERS_DYING) reports its completion at the end of its work through cpu_stop_signal_done() and performs a wake up that eventually arms the deadline server timer: WARNING: CPU: 94 PID: 588 at kernel/time/hrtimer.c:1086 hrtimer_start_range_ns+0x289/0x2d0 CPU: 94 UID: 0 PID: 588 Comm: migration/94 Not tainted Stopper: multi_cpu_stop+0x0/0x120 <- stop_machine_cpuslocked+0x66/0xc0 RIP: 0010:hrtimer_start_range_ns+0x289/0x2d0 Call Trace: <TASK> start_dl_timer enqueue_dl_entity dl_server_start enqueue_task_fair enqueue_task ttwu_do_activate try_to_wake_up complete cpu_stopper_thread Instead of providing yet another bandaid to work around the situation, fix it in the hrtimers infrastructure instead: always migrate away a timer to an online target whenever it is enqueued from an offline CPU. This will also allow to revert all the above RCU disgraceful hacks.

[PATCH OLK-6.6] iommufd/iova_bitmap: Fix shift-out-of-bounds in iova_bitmap_offset_to_index()

The constant "1" defaults to a 32-bit "int", and when "pgshift" exceeds 31 (e.g., pgshift = 63) the shift operation overflows, as the result cannot be represented in a 32-bit type. To resolve this, the constant is updated to "1UL", promoting it to an unsigned long type to match the operand's type.

[PATCH OLK-6.6] PCI: dwc: ep: Prevent changing BAR size/flags in pci_epc_set_bar()
by Xiongfeng Wang 13 Mar '25

13 Mar '25

From: Niklas Cassel <cassel(a)kernel.org> mainline inclusion from mainline-v6.14-rc1 commit 3708acbd5f169ebafe1faa519cb28adc56295546 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBPC3J CVE: CVE-2024-58006 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- In commit 4284c88fff0e ("PCI: designware-ep: Allow pci_epc_set_bar() update inbound map address") set_bar() was modified to support dynamically changing the backing physical address of a BAR that was already configured. This means that set_bar() can be called twice, without ever calling clear_bar() (as calling clear_bar() would clear the BAR's PCI address assigned by the host). This can only be done if the new BAR size/flags does not differ from the existing BAR configuration. Add these missing checks. If we allow set_bar() to set e.g. a new BAR size that differs from the existing BAR size, the new address translation range will be smaller than the BAR size already determined by the host, which would mean that a read past the new BAR size would pass the iATU untranslated, which could allow the host to read memory not belonging to the new struct pci_epf_bar. While at it, add comments which clarifies the support for dynamically changing the physical address of a BAR. (Which was also missing.)

[PATCH OLK-6.6] afs: Fix the maximum cell name length

From: David Howells <dhowells(a)redhat.com> mainline inclusion from mainline-v6.13-rc7 commit 8fd56ad6e7c90ac2bddb0741c6b248c8c5d56ac8 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBIQQL CVE: CVE-2025-21646 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- The kafs filesystem limits the maximum length of a cell to 256 bytes, but a problem occurs if someone actually does that: kafs tries to create a directory under /proc/net/afs/ with the name of the cell, but that fails with a warning: WARNING: CPU: 0 PID: 9 at fs/proc/generic.c:405 because procfs limits the maximum filename length to 255. However, the DNS limits the maximum lookup length and, by extension, the maximum cell name, to 255 less two (length count and trailing NUL). Fix this by limiting the maximum acceptable cellname length to 253. This also allows us to be sure we can create the "/afs/.<cell>/" mountpoint too. Further, split the YFS VL record cell name maximum to be the 256 allowed by the protocol and ignore the record retrieved by YFSVL.GetCellName if it exceeds 253.

[PATCH openEuler-1.0-LTS] powerpc/pseries: Fix use after free in remove_phb_dynamic()
by Qi Xi 13 Mar '25

13 Mar '25

From: Michael Ellerman <mpe(a)ellerman.id.au> mainline inclusion from mainline-v5.18-rc1 commit fe2640bd7a62f1f7c3f55fbda31084085075bc30 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBP1SK CVE: CVE-2022-49196 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- In remove_phb_dynamic() we use &phb->io_resource, after we've called device_unregister(&host_bridge->dev). But the unregister may have freed phb, because pcibios_free_controller_deferred() is the release function for the host_bridge. If there are no outstanding references when we call device_unregister() then phb will be freed out from under us. This has gone mainly unnoticed, but with slub_debug and page_poison enabled it can lead to a crash: PID: 7574 TASK: c0000000d492cb80 CPU: 13 COMMAND: "drmgr" #0 [c0000000e4f075a0] crash_kexec at c00000000027d7dc #1 [c0000000e4f075d0] oops_end at c000000000029608 #2 [c0000000e4f07650] __bad_page_fault at c0000000000904b4 #3 [c0000000e4f076c0] do_bad_slb_fault at c00000000009a5a8 #4 [c0000000e4f076f0] data_access_slb_common_virt at c000000000008b30 Data SLB Access [380] exception frame: R0: c000000000167250 R1: c0000000e4f07a00 R2: c000000002a46100 R3: c000000002b39ce8 R4: 00000000000000c0 R5: 00000000000000a9 R6: 3894674d000000c0 R7: 0000000000000000 R8: 00000000000000ff R9: 0000000000000100 R10: 6b6b6b6b6b6b6b6b R11: 0000000000008000 R12: c00000000023da80 R13: c0000009ffd38b00 R14: 0000000000000000 R15: 000000011c87f0f0 R16: 0000000000000006 R17: 0000000000000003 R18: 0000000000000002 R19: 0000000000000004 R20: 0000000000000005 R21: 000000011c87ede8 R22: 000000011c87c5a8 R23: 000000011c87d3a0 R24: 0000000000000000 R25: 0000000000000001 R26: c0000000e4f07cc8 R27: c00000004d1cc400 R28: c0080000031d00e8 R29: c00000004d23d800 R30: c00000004d1d2400 R31: c00000004d1d2540 NIP: c000000000167258 MSR: 8000000000009033 OR3: c000000000e9f474 CTR: 0000000000000000 LR: c000000000167250 XER: 0000000020040003 CCR: 0000000024088420 MQ: 0000000000000000 DAR: 6b6b6b6b6b6b6ba3 DSISR: c0000000e4f07920 Syscall Result: fffffffffffffff2 [NIP : release_resource+56] [LR : release_resource+48] #5 [c0000000e4f07a00] release_resource at c000000000167258 (unreliable) #6 [c0000000e4f07a30] remove_phb_dynamic at c000000000105648 #7 [c0000000e4f07ab0] dlpar_remove_slot at c0080000031a09e8 [rpadlpar_io] #8 [c0000000e4f07b50] remove_slot_store at c0080000031a0b9c [rpadlpar_io] #9 [c0000000e4f07be0] kobj_attr_store at c000000000817d8c #10 [c0000000e4f07c00] sysfs_kf_write at c00000000063e504 #11 [c0000000e4f07c20] kernfs_fop_write_iter at c00000000063d868 #12 [c0000000e4f07c70] new_sync_write at c00000000054339c #13 [c0000000e4f07d10] vfs_write at c000000000546624 #14 [c0000000e4f07d60] ksys_write at c0000000005469f4 #15 [c0000000e4f07db0] system_call_exception at c000000000030840 #16 [c0000000e4f07e10] system_call_vectored_common at c00000000000c168 To avoid it, we can take a reference to the host_bridge->dev until we're done using phb.

[PATCH OLK-6.6 v2 1/2] fuse: cleanup request queuing towards virtiofs
by Yang Erkun 13 Mar '25

13 Mar '25

From: Miklos Szeredi <mszeredi(a)redhat.com> mainline inclusion from mainline-v6.12-rc1 commit 5de8acb41c86f1d335d165e0a350441ea3a1f480 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBT4CQ Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- Virtiofs has its own queuing mechanism, but still requests are first queued on fiq->pending to be immediately dequeued and queued onto the virtio queue. The queuing on fiq->pending is unnecessary and might even have some performance impact due to being a contention point. Forget requests are handled similarly. Move the queuing of requests and forgets into the fiq->ops->*. fuse_iqueue_ops are renamed to reflect the new semantics.

[PATCH OLK-5.10] scsi: lpfc: Fix null pointer dereference after failing to issue FLOGI and PLOGI
by Guo Mengqi 13 Mar '25

13 Mar '25

From: James Smart <jsmart2021(a)gmail.com> mainline inclusion from mainline-v5.19-rc1 commit 577a942df3de2666f6947bdd3a5c9e8d30073424 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBP6SH CVE: CVE-2022-49535 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- [ Upstream commit 577a942df3de2666f6947bdd3a5c9e8d30073424 ] If lpfc_issue_els_flogi() fails and returns non-zero status, the node reference count is decremented to trigger the release of the nodelist structure. However, if there is a prior registration or dev-loss-evt work pending, the node may be released prematurely. When dev-loss-evt completes, the released node is referenced causing a use-after-free null pointer dereference. Similarly, when processing non-zero ELS PLOGI completion status in lpfc_cmpl_els_plogi(), the ndlp flags are checked for a transport registration before triggering node removal. If dev-loss-evt work is pending, the node may be released prematurely and a subsequent call to lpfc_dev_loss_tmo_handler() results in a use after free ndlp dereference. Add test for pending dev-loss before decrementing the node reference count for FLOGI, PLOGI, PRLI, and ADISC handling.

[PATCH openEuler-1.0-LTS] net: mdio: unexport __init-annotated mdio_bus_init()

From: Masahiro Yamada <masahiroy(a)kernel.org> stable inclusion from stable-v4.19.247 commit 5534bcd7c40299862237c4a8fd9c5031b3db1538 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBPK8Q CVE: CVE-2022-49350 Reference: https://web.git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit… -------------------------------- [ Upstream commit 35b42dce619701f1300fb8498dae82c9bb1f0263 ] EXPORT_SYMBOL and __init is a bad combination because the .init.text section is freed up after the initialization. Hence, modules cannot use symbols annotated __init. The access to a freed symbol may end up with kernel panic. modpost used to detect it, but it has been broken for a decade. Recently, I fixed modpost so it started to warn it again, then this showed up in linux-next builds. There are two ways to fix it: - Remove __init - Remove EXPORT_SYMBOL I chose the latter for this case because the only in-tree call-site, drivers/net/phy/phy_device.c is never compiled as modular. (CONFIG_PHYLIB is boolean) Fixes: 90eff9096c01 ("net: phy: Allow splitting MDIO bus/device support from PHYs") Reported-by: Stephen Rothwell <sfr(a)canb.auug.org.au> Signed-off-by: Masahiro Yamada <masahiroy(a)kernel.org> Reviewed-by: Florian Fainelli <f.fainelli(a)gmail.com> Reviewed-by: Russell King (Oracle) <rmk+kernel(a)armlinux.org.uk> Signed-off-by: Jakub Kicinski <kuba(a)kernel.org> Signed-off-by: Sasha Levin <sashal(a)kernel.org> Signed-off-by: Wenyu Huang <huangwenyu5(a)huawei.com> --- drivers/net/phy/mdio_bus.c | 1 - 1 file changed, 1 deletion(-) diff --git a/drivers/net/phy/mdio_bus.c b/drivers/net/phy/mdio_bus.c index 82cc1983c09a..35937175c4e8 100644 --- a/drivers/net/phy/mdio_bus.c +++ b/drivers/net/phy/mdio_bus.c @@ -745,7 +745,6 @@ int __init mdio_bus_init(void) return ret; } -EXPORT_SYMBOL_GPL(mdio_bus_init); #if IS_ENABLED(CONFIG_PHYLIB) void mdio_bus_exit(void) -- 2.34.1

From: Jessica Zhang <quic_jesszhan(a)quicinc.com> stable inclusion from stable-v4.19.247 commit 776f5c58bfe16cf322d71eeed3c5dda1eeac7e6b category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBP1O4 CVE: CVE-2022-49490 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit d59be579fa932c46b908f37509f319cbd4ca9a68 ] mdp5_get_global_state runs the risk of hitting a -EDEADLK when acquiring the modeset lock, but currently mdp5_pipe_release doesn't check for if an error is returned. Because of this, there is a possibility of mdp5_pipe_release hitting a NULL dereference error. To avoid this, let's have mdp5_pipe_release check if mdp5_get_global_state returns an error and propogate that error. Changes since v1: - Separated declaration and initialization of *new_state to avoid compiler warning - Fixed some spelling mistakes in commit message Changes since v2: - Return 0 in case where hwpipe is NULL as this is considered normal behavior - Added 2nd patch in series to fix a similar NULL dereference issue in mdp5_mixer_release Reported-by: Tomeu Vizoso <tomeu.vizoso(a)collabora.com> Signed-off-by: Jessica Zhang <quic_jesszhan(a)quicinc.com> Fixes: 7907a0d77cb4 ("drm/msm/mdp5: Use the new private_obj state") Reviewed-by: Rob Clark <robdclark(a)gmail.com> Reviewed-by: Dmitry Baryshkov <dmitry.baryshkov(a)linaro.org> Patchwork: https://patchwork.freedesktop.org/patch/485179/ Link: https://lore.kernel.org/r/20220505214051.155-1-quic_jesszhan@quicinc.com Signed-off-by: Dmitry Baryshkov <dmitry.baryshkov(a)linaro.org> Signed-off-by: Sasha Levin <sashal(a)kernel.org> Signed-off-by: Zeng Heng <zengheng4(a)huawei.com> --- drivers/gpu/drm/msm/disp/mdp5/mdp5_pipe.c | 15 +++++++++++---- drivers/gpu/drm/msm/disp/mdp5/mdp5_pipe.h | 2 +- drivers/gpu/drm/msm/disp/mdp5/mdp5_plane.c | 20 ++++++++++++++++---- 3 files changed, 28 insertions(+), 9 deletions(-) diff --git a/drivers/gpu/drm/msm/disp/mdp5/mdp5_pipe.c b/drivers/gpu/drm/msm/disp/mdp5/mdp5_pipe.c index 1ef26bc63163..88de12225582 100644 --- a/drivers/gpu/drm/msm/disp/mdp5/mdp5_pipe.c +++ b/drivers/gpu/drm/msm/disp/mdp5/mdp5_pipe.c @@ -130,18 +130,23 @@ int mdp5_pipe_assign(struct drm_atomic_state *s, struct drm_plane *plane, return 0; } -void mdp5_pipe_release(struct drm_atomic_state *s, struct mdp5_hw_pipe *hwpipe) +int mdp5_pipe_release(struct drm_atomic_state *s, struct mdp5_hw_pipe *hwpipe) { struct msm_drm_private *priv = s->dev->dev_private; struct mdp5_kms *mdp5_kms = to_mdp5_kms(to_mdp_kms(priv->kms)); struct mdp5_global_state *state = mdp5_get_global_state(s); - struct mdp5_hw_pipe_state *new_state = &state->hwpipe; + struct mdp5_hw_pipe_state *new_state; if (!hwpipe) - return; + return 0; + + if (IS_ERR(state)) + return PTR_ERR(state); + + new_state = &state->hwpipe; if (WARN_ON(!new_state->hwpipe_to_plane[hwpipe->idx])) - return; + return -EINVAL; DBG("%s: release from plane %s", hwpipe->name, new_state->hwpipe_to_plane[hwpipe->idx]->name); @@ -152,6 +157,8 @@ void mdp5_pipe_release(struct drm_atomic_state *s, struct mdp5_hw_pipe *hwpipe) } new_state->hwpipe_to_plane[hwpipe->idx] = NULL; + + return 0; } void mdp5_pipe_destroy(struct mdp5_hw_pipe *hwpipe) diff --git a/drivers/gpu/drm/msm/disp/mdp5/mdp5_pipe.h b/drivers/gpu/drm/msm/disp/mdp5/mdp5_pipe.h index bb2b0ac7aa2b..072db6a99b85 100644 --- a/drivers/gpu/drm/msm/disp/mdp5/mdp5_pipe.h +++ b/drivers/gpu/drm/msm/disp/mdp5/mdp5_pipe.h @@ -48,7 +48,7 @@ int mdp5_pipe_assign(struct drm_atomic_state *s, struct drm_plane *plane, uint32_t caps, uint32_t blkcfg, struct mdp5_hw_pipe **hwpipe, struct mdp5_hw_pipe **r_hwpipe); -void mdp5_pipe_release(struct drm_atomic_state *s, struct mdp5_hw_pipe *hwpipe); +int mdp5_pipe_release(struct drm_atomic_state *s, struct mdp5_hw_pipe *hwpipe); struct mdp5_hw_pipe *mdp5_pipe_init(enum mdp5_pipe pipe, uint32_t reg_offset, uint32_t caps); diff --git a/drivers/gpu/drm/msm/disp/mdp5/mdp5_plane.c b/drivers/gpu/drm/msm/disp/mdp5/mdp5_plane.c index 1ddf07514de6..85bbae26b17e 100644 --- a/drivers/gpu/drm/msm/disp/mdp5/mdp5_plane.c +++ b/drivers/gpu/drm/msm/disp/mdp5/mdp5_plane.c @@ -399,12 +399,24 @@ static int mdp5_plane_atomic_check_with_state(struct drm_crtc_state *crtc_state, mdp5_state->r_hwpipe = NULL; - mdp5_pipe_release(state->state, old_hwpipe); - mdp5_pipe_release(state->state, old_right_hwpipe); + ret = mdp5_pipe_release(state->state, old_hwpipe); + if (ret) + return ret; + + ret = mdp5_pipe_release(state->state, old_right_hwpipe); + if (ret) + return ret; + } } else { - mdp5_pipe_release(state->state, mdp5_state->hwpipe); - mdp5_pipe_release(state->state, mdp5_state->r_hwpipe); + ret = mdp5_pipe_release(state->state, mdp5_state->hwpipe); + if (ret) + return ret; + + ret = mdp5_pipe_release(state->state, mdp5_state->r_hwpipe); + if (ret) + return ret; + mdp5_state->hwpipe = mdp5_state->r_hwpipe = NULL; } -- 2.25.1

From: Hristo Venev <hristo(a)venev.name> stable inclusion from stable-v4.19.254 commit 8ff4f9df73e5c551a72ee6034886c17e8de6596d category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBP6VF CVE: CVE-2022-49581 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit d7241f679a59cfe27f92cb5c6272cb429fb1f7ec ] be_cmd_read_port_transceiver_data assumes that it is given a buffer that is at least PAGE_DATA_LEN long, or twice that if the module supports SFF 8472. However, this is not always the case. Fix this by passing the desired offset and length to be_cmd_read_port_transceiver_data so that we only copy the bytes once.

[PATCH OLK-6.6] perf: Configure BRBE correctly on VHE host
by Yushan Wang 12 Mar '25

12 Mar '25

From: Yicong Yang <yangyicong(a)hisilicon.com> driver inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBSI0M CVE: NA ---------------------------------------------------------------------- The BRBE support backported of v18 didn't configure the BRBCR_EL1 correctly which will miss some key functions like FZP during sampling. In VHE mode with MDCR_EL2.HPMN set to PMCR_EL0.N, the counters are controlled by BRBCR_EL1 rather than BRBCR_EL2 (which writes to BRBCR_EL1 are redirected to). Use the same value for both register except keep EL1 and EL0 recording disabled in guests. The fix is backported from the v19 version [1].

[PATCH openEuler-1.0-LTS] sfc: fix kernel panic when creating VF

From: Íñigo Huguet <ihuguet(a)redhat.com> stable inclusion from stable-v4.19.253 commit 82bcb730f856086f033e6c04082eb4503d4c2fa4 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBP5WM CVE: CVE-2022-49625 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit ada74c5539eba06cf8b47d068f92e0b3963a9a6e ] When creating VFs a kernel panic can happen when calling to efx_ef10_try_update_nic_stats_vf. When releasing a DMA coherent buffer, sometimes, I don't know in what specific circumstances, it has to unmap memory with vunmap. It is disallowed to do that in IRQ context or with BH disabled. Otherwise, we hit this line in vunmap, causing the crash: BUG_ON(in_interrupt()); This patch reenables BH to release the buffer.

[PATCH OLK-5.10] RDMA/hns: Fix mbox timing out by adding retry mechanism
by Junxian Huang 12 Mar '25

12 Mar '25

maillist inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBSLDS CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma.git/commit/?h=wip… ---------------------------------------------------------------------- If a QP is modified to error state and a flush CQE process is triggered, the subsequent QP destruction mbox can still be successfully posted but will be blocked in HW until the flush CQE process finishes. This causes further mbox posting timeouts in driver. The blocking time is related to QP depth. Considering an extreme case where SQ depth and RQ depth are both 32K, the blocking time can reach about 135ms. This patch adds a retry mechanism for mbox posting. For each try, FW waits 15ms for HW to complete the previous mbox, otherwise return a timeout error code to driver. Counting other time consumption in FW, set 8 tries for mbox posting and a 5ms time gap before each retry to increase to a sufficient timeout limit.

[PATCH OLK-6.6] perf: Configure BRBE correctly on VHE host
by Yushan Wang 12 Mar '25

12 Mar '25

From: Yicong Yang <yangyicong(a)hisilicon.com> driver inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBSI0M CVE: NA ---------------------------------------------------------------------- The BRBE support backported of v18 didn't configure the BRBCR_EL1 correctly which will miss some key functions like FZP during sampling. In VHE mode with MDCR_EL2.HPMN set to PMCR_EL0.N, the counters are controlled by BRBCR_EL1 rather than BRBCR_EL2 (which writes to BRBCR_EL1 are redirected to). Use the same value for both register except keep EL1 and EL0 recording disabled in guests. The fix is backported from the v19 version [1].

[PATCH openEuler-1.0-LTS] hrtimers: Handle CPU state correctly on hotplug
by Zeng Heng 11 Mar '25

11 Mar '25

From: Koichiro Den <koichiro.den(a)canonical.com> stable inclusion from stable-v6.6.74 commit a5cbbea145b400e40540c34816d16d36e0374fbc category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBLWTN CVE: CVE-2024-57951 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 2f8dea1692eef2b7ba6a256246ed82c365fdc686 upstream. Consider a scenario where a CPU transitions from CPUHP_ONLINE to halfway through a CPU hotunplug down to CPUHP_HRTIMERS_PREPARE, and then back to CPUHP_ONLINE: Since hrtimers_prepare_cpu() does not run, cpu_base.hres_active remains set to 1 throughout. However, during a CPU unplug operation, the tick and the clockevents are shut down at CPUHP_AP_TICK_DYING. On return to the online state, for instance CFS incorrectly assumes that the hrtick is already active, and the chance of the clockevent device to transition to oneshot mode is also lost forever for the CPU, unless it goes back to a lower state than CPUHP_HRTIMERS_PREPARE once. This round-trip reveals another issue; cpu_base.online is not set to 1 after the transition, which appears as a WARN_ON_ONCE in enqueue_hrtimer(). Aside of that, the bulk of the per CPU state is not reset either, which means there are dangling pointers in the worst case. Address this by adding a corresponding startup() callback, which resets the stale per CPU state and sets the online flag.

[PATCH] RDMA/hns: Fix mbox timing out by adding retry mechanism
by Junxian Huang 11 Mar '25

11 Mar '25

maillist inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBSLDS CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma.git/commit/?h=wip… ---------------------------------------------------------------------- If a QP is modified to error state and a flush CQE process is triggered, the subsequent QP destruction mbox can still be successfully posted but will be blocked in HW until the flush CQE process finishes. This causes further mbox posting timeouts in driver. The blocking time is related to QP depth. Considering an extreme case where SQ depth and RQ depth are both 32K, the blocking time can reach about 135ms. This patch adds a retry mechanism for mbox posting. For each try, FW waits 15ms for HW to complete the previous mbox, otherwise return a timeout error code to driver. Counting other time consumption in FW, set 8 tries for mbox posting and a 5ms time gap before each retry to increase to a sufficient timeout limit.

From: Aleksandr Loktionov <aleksandr.loktionov(a)intel.com> stable inclusion from stable-v4.19.24 commit 15950157e2c24865b696db1c9ccc72743ae0e967 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBP4HT CVE: CVE-2022-49725 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… ---------------------------------------------------------------------- [ Upstream commit fd5855e6b1358e816710afee68a1d2bc685176ca ] After PF reset and ethtool -t there was call trace in dmesg sometimes leading to panic. When there was some time, around 5 seconds, between reset and test there were no errors. Problem was that pf reset calls i40e_vsi_close in prep_for_reset and ethtool -t calls i40e_vsi_close in diag_test. If there was not enough time between those commands the second i40e_vsi_close starts before previous i40e_vsi_close was done which leads to crash. Add check to diag_test if pf is in reset and don't start offline tests if it is true. Add netif_info("testing failed") into unhappy path of i40e_diag_test() Fixes: e17bc411aea8 ("i40e: Disable offline diagnostics if VFs are enabled") Fixes: 510efb2682b3 ("i40e: Fix ethtool offline diagnostic with netqueues") Signed-off-by: Michal Jaron <michalx.jaron(a)intel.com> Signed-off-by: Aleksandr Loktionov <aleksandr.loktionov(a)intel.com> Tested-by: Gurucharan <gurucharanx.g(a)intel.com> (A Contingent worker at Intel) Signed-off-by: Tony Nguyen <anthony.l.nguyen(a)intel.com> Signed-off-by: Sasha Levin <sashal(a)kernel.org> Signed-off-by: Chen Ridong <chenridong(a)huawei.com> Reviewed-by: Xiu Jianfeng <xiujianfeng(a)huawei.com> --- .../net/ethernet/intel/i40e/i40e_ethtool.c | 25 +++++++++++++------ 1 file changed, 17 insertions(+), 8 deletions(-) diff --git a/drivers/net/ethernet/intel/i40e/i40e_ethtool.c b/drivers/net/ethernet/intel/i40e/i40e_ethtool.c index a6b0f605a7d8..50f56a51bbc7 100644 --- a/drivers/net/ethernet/intel/i40e/i40e_ethtool.c +++ b/drivers/net/ethernet/intel/i40e/i40e_ethtool.c @@ -2195,15 +2195,16 @@ static void i40e_diag_test(struct net_device *netdev, set_bit(__I40E_TESTING, pf->state); + if (test_bit(__I40E_RESET_RECOVERY_PENDING, pf->state) || + test_bit(__I40E_RESET_INTR_RECEIVED, pf->state)) { + dev_warn(&pf->pdev->dev, + "Cannot start offline testing when PF is in reset state.\n"); + goto skip_ol_tests; + } + if (i40e_active_vfs(pf) || i40e_active_vmdqs(pf)) { dev_warn(&pf->pdev->dev, "Please take active VFs and Netqueues offline and restart the adapter before running NIC diagnostics\n"); - data[I40E_ETH_TEST_REG] = 1; - data[I40E_ETH_TEST_EEPROM] = 1; - data[I40E_ETH_TEST_INTR] = 1; - data[I40E_ETH_TEST_LINK] = 1; - eth_test->flags |= ETH_TEST_FL_FAILED; - clear_bit(__I40E_TESTING, pf->state); goto skip_ol_tests; } @@ -2250,9 +2251,17 @@ static void i40e_diag_test(struct net_device *netdev, data[I40E_ETH_TEST_INTR] = 0; } -skip_ol_tests: - netif_info(pf, drv, netdev, "testing finished\n"); + return; + +skip_ol_tests: + data[I40E_ETH_TEST_REG] = 1; + data[I40E_ETH_TEST_EEPROM] = 1; + data[I40E_ETH_TEST_INTR] = 1; + data[I40E_ETH_TEST_LINK] = 1; + eth_test->flags |= ETH_TEST_FL_FAILED; + clear_bit(__I40E_TESTING, pf->state); + netif_info(pf, drv, netdev, "testing failed\n"); } static void i40e_get_wol(struct net_device *netdev, -- 2.34.1

[PATCH OLK-5.10] ubi: fastmap: wl: Schedule fm_work if wear-leveling pool is empty
by Wang Zhaolong 10 Mar '25

10 Mar '25

From: Zhihao Cheng <chengzhihao1(a)huawei.com> mainline inclusion from mainline-v6.13-rc1 commit c4595fe394a289927077e3da561db27811919ee0 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBS8G5 CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Since commit 14072ee33d5a ("ubi: fastmap: Check wl_pool for free peb before wear leveling"), wear_leveling_worker() won't schedule fm_work if wear-leveling pool is empty, which could temporarily disable the wear-leveling until the fastmap is updated(eg. pool becomes empty). Fix it by scheduling fm_work if wl_pool is empty during wear-leveing.

From: Martin KaFai Lau <martin.lau(a)kernel.org> stable inclusion from stable-v6.6.76 commit 3392fa605d7c5708c5fbe02e4fbdac547c3b7352 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBREBI CVE: CVE-2024-58070 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 8eef6ac4d70eb1f0099fff93321d90ce8fa49ee1 ] In PREEMPT_RT, kmalloc(GFP_ATOMIC) is still not safe in non preemptible context. bpf_mem_alloc must be used in PREEMPT_RT. This patch is to enforce bpf_mem_alloc in the bpf_local_storage when CONFIG_PREEMPT_RT is enabled.

It has been an old issue since the first introduction of the bpf_local_storage ~5 years ago, so this patch targets the bpf-next. bpf_mem_alloc is needed to solve it, so the Fixes tag is set to the commit when bpf_mem_alloc was first used in the bpf_local_storage.

[PATCH OLK-5.10] ocfs2: handle a symlink read error correctly

From: "Matthew Wilcox (Oracle)" <willy(a)infradead.org> mainline inclusion from mainline-v6.14-rc1 commit 2b4c2094da6d84e69b843dd3317902e977bf64bd category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBPC8H CVE: CVE-2024-58001 Reference: https://git.kernel.org/stable/c/2b4c2094da6d84e69b843dd3317902e977bf64bd -------------------------------- Patch series "Convert ocfs2 to use folios". Mark did a conversion of ocfs2 to use folios and sent it to me as a giant patch for review ;-) So I've redone it as individual patches, and credited Mark for the patches where his code is substantially the same. It's not a bad way to do it; his patch had some bugs and my patches had some bugs. Hopefully all our bugs were different from each other. And hopefully Mark likes all the changes I made to his code! This patch (of 23): If we can't read the buffer, be sure to unlock the page before returning.

Mark did a conversion of ocfs2 to use folios and sent it to me as a giant patch for review ;-) So I've redone it as individual patches, and credited Mark for the patches where his code is substantially the same. It's not a bad way to do it; his patch had some bugs and my patches had some bugs. Hopefully all our bugs were different from each other. And hopefully Mark likes all the changes I made to his code!

[PATCH openEuler-1.0-LTS] tracing/histograms: Fix memory leak problem
by Li Huafei 10 Mar '25

10 Mar '25

From: Zheng Yejian <zhengyejian1(a)huawei.com> stable inclusion from stable-v4.19.253 commit eb622d5580b9e2ff694f62da6410618bd73853cb category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBP6IV CVE: CVE-2022-49648 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 7edc3945bdce9c39198a10d6129377a5c53559c2 upstream. This reverts commit 46bbe5c671e06f070428b9be142cc4ee5cedebac. As commit 46bbe5c671e0 ("tracing: fix double free") said, the "double free" problem reported by clang static analyzer is: > In parse_var_defs() if there is a problem allocating > var_defs.expr, the earlier var_defs.name is freed. > This free is duplicated by free_var_defs() which frees > the rest of the list. However, if there is a problem allocating N-th var_defs.expr: + in parse_var_defs(), the freed 'earlier var_defs.name' is actually the N-th var_defs.name; + then in free_var_defs(), the names from 0th to (N-1)-th are freed; IF ALLOCATING PROBLEM HAPPENED HERE!!! -+ \ | 0th 1th (N-1)-th N-th V +-------------+-------------+-----+-------------+----------- var_defs: | name | expr | name | expr | ... | name | expr | name | /// +-------------+-------------+-----+-------------+----------- These two frees don't act on same name, so there was no "double free" problem before. Conversely, after that commit, we get a "memory leak" problem because the above "N-th var_defs.name" is not freed. If enable CONFIG_DEBUG_KMEMLEAK and inject a fault at where the N-th var_defs.expr allocated, then execute on shell like: $ echo 'hist:key=call_site:val=$v1,$v2:v1=bytes_req,v2=bytes_alloc' > \ /sys/kernel/debug/tracing/events/kmem/kmalloc/trigger Then kmemleak reports: unreferenced object 0xffff8fb100ef3518 (size 8): comm "bash", pid 196, jiffies 4295681690 (age 28.538s) hex dump (first 8 bytes): 76 31 00 00 b1 8f ff ff v1...... backtrace: [<0000000038fe4895>] kstrdup+0x2d/0x60 [<00000000c99c049a>] event_hist_trigger_parse+0x206f/0x20e0 [<00000000ae70d2cc>] trigger_process_regex+0xc0/0x110 [<0000000066737a4c>] event_trigger_write+0x75/0xd0 [<000000007341e40c>] vfs_write+0xbb/0x2a0 [<0000000087fde4c2>] ksys_write+0x59/0xd0 [<00000000581e9cdf>] do_syscall_64+0x3a/0x80 [<00000000cf3b065c>] entry_SYSCALL_64_after_hwframe+0x46/0xb0 Link: https://lkml.kernel.org/r/20220711014731.69520-1-zhengyejian1@huawei.com Cc: stable(a)vger.kernel.org Fixes: 46bbe5c671e0 ("tracing: fix double free") Reported-by: Hulk Robot <hulkci(a)huawei.com> Suggested-by: Steven Rostedt <rostedt(a)goodmis.org> Reviewed-by: Tom Zanussi <tom.zanussi(a)linux.intel.com> Signed-off-by: Zheng Yejian <zhengyejian1(a)huawei.com> Signed-off-by: Steven Rostedt (Google) <rostedt(a)goodmis.org> Signed-off-by: Greg Kroah-Hartman <gregkh(a)linuxfoundation.org> Signed-off-by: Li Huafei <lihuafei1(a)huawei.com> --- kernel/trace/trace_events_hist.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/kernel/trace/trace_events_hist.c b/kernel/trace/trace_events_hist.c index 638566ea7839..2f57eb241ac9 100644 --- a/kernel/trace/trace_events_hist.c +++ b/kernel/trace/trace_events_hist.c @@ -4155,6 +4155,8 @@ static int parse_var_defs(struct hist_trigger_data *hist_data) s = kstrdup(field_str, GFP_KERNEL); if (!s) { + kfree(hist_data->attrs->var_defs.name[n_vars]); + hist_data->attrs->var_defs.name[n_vars] = NULL; ret = -ENOMEM; goto free; } -- 2.25.1

[PATCH openEuler-1.0-LTS v2 0/2] Ignore SB_RDONLY when mounting and remounting nfs
by Li Lingfeng 08 Mar '25

08 Mar '25

When NFS_MOUNT_UNSHARED is not set, NFS forces the sharing of a superblock among each filesystem that mounts sub-directories elonging to a single exported root path. To prevent interference between different filesystems, ignore SB_RDONLY when mounting and remounting nfs. Li Lingfeng (2): nfs: clear SB_RDONLY before getting superblock nfs: ignore SB_RDONLY when remounting nfs --- Changes in v2: - Change the bugzilla tag to the gitee link. --- fs/nfs/super.c | 19 +++++++++++++++++++ 1 file changed, 19 insertions(+) -- 2.31.1
