commit fbba8b00bbe4e4f958a2b0654cc1219a7e6597f6
category: bugfix
bugzilla: https://atomgit.com/src-openeuler/kernel/issues/13373
CVE: CVE-2025-68821
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id…
--------------------------------
commit bd5603eaae0aabf527bfb3ce1bb07e979ce5bd50 upstream.
Commit e26ee4efbc79 ("fuse: allocate ff->release_args only if release is
needed") skips allocating ff->release_args if the server does not
implement open. However in doing so, fuse_prepare_release() now skips
grabbing the reference on the inode, which makes it possible for an
inode to be evicted from the dcache while there are inflight readahead
requests. This causes a deadlock if the server triggers reclaim while
servicing the readahead request and reclaim attempts to evict the inode
of the file being read ahead. Since the folio is locked during
readahead, when reclaim evicts the fuse inode and fuse_evict_inode()
attempts to remove all folios associated with the inode from the page
cache (truncate_inode_pages_range()), reclaim will block forever waiting
for the lock since readahead cannot relinquish the lock because it is
itself blocked in reclaim:

Fix this deadlock by allocating ff->release_args and grabbing the
reference on the inode when preparing the file for release even if the
server does not implement open. The inode reference will be dropped when
the last reference on the fuse file is dropped (see fuse_file_put() ->
fuse_release_end()).

--------------------------------
commit 95c39eef7c2b666026c69ab5b30471da94ea2874 upstream.
When a request is terminated before it has been committed, the request
is not removed from the queue's list. This leaves a dangling list entry
that leads to list corruption and use-after-free issues.
Remove the request from the queue's list for terminated non-committed
requests.

[PATCH OLK-6.6] fsnotify: do not generate ACCESS/MODIFY events on child for special files

bugzilla: https://atomgit.com/src-openeuler/kernel/issues/13341
CVE: CVE-2025-68788
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id…
--------------------------------
commit 635bc4def026a24e071436f4f356ea08c0eed6ff upstream.
inotify/fanotify do not allow users with no read access to a file to
subscribe to events (e.g. IN_ACCESS/IN_MODIFY), but they do allow the
same user to subscribe for watching events on children when the user
has access to the parent directory (e.g. /dev).
Users with no read access to a file but with read access to its parent
directory can still stat the file and see if it was accessed/modified
via atime/mtime change.
The same is not true for special files (e.g. /dev/null). Users will not
generally observe atime/mtime changes when other users read/write to
special files, only when someone sets atime/mtime via utimensat().
Align fsnotify events with this stat behavior and do not generate
ACCESS/MODIFY events to parent watchers on read/write of special files.
The events are still generated to parent watchers on utimensat(). This
closes some side-channels that could be possibly used for information
exfiltration [1].

[ Upstream commit 8b0e69763ef948fb872a7767df4be665d18f5fd4 ]
We sometimes observe use-after-free when dereferencing a neighbour [1].
The problem seems to be that the driver stores a pointer to the
neighbour, but without holding a reference on it. A reference is only
taken when the neighbour is used by a nexthop.
Fix by simplifying the reference counting scheme. Always take a
reference when storing a neighbour pointer in a neighbour entry. Avoid
taking a referencing when the neighbour is used by a nexthop as the
neighbour entry associated with the nexthop already holds a reference.
Tested by running the test that uncovered the problem over 300 times.
Without this patch the problem was reproduced after a handful of
iterations.

[PATCH OLK-6.6] mlxsw: spectrum_mr: Fix use-after-free when updating multicast route stats

category: bugfix
bugzilla: https://atomgit.com/src-openeuler/kernel/issues/13353
CVE: CVE-2025-68800
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id…
--------------------------------
[ Upstream commit 8ac1dacec458f55f871f7153242ed6ab60373b90 ]
Cited commit added a dedicated mutex (instead of RTNL) to protect the
multicast route list, so that it will not change while the driver
periodically traverses it in order to update the kernel about multicast
route stats that were queried from the device.
One instance of list entry deletion (during route replace) was missed
and it can result in a use-after-free [1].
Fix by acquiring the mutex before deleting the entry from the list and
releasing it afterwards.
[1]

[PATCH OLK-6.6] ptr_ring: do not block hard interrupts in ptr_ring_resize_multiple()

-------------------------------------------------
Jakub added a lockdep_assert_no_hardirq() check in __page_pool_put_page()
to increase test coverage.
syzbot found a splat caused by hard irq blocking in
ptr_ring_resize_multiple() [1]
As current users of ptr_ring_resize_multiple() do not require
hard irqs being masked, replace it to only block BH.
Rename helpers to better reflect they are safe against BH only.
- ptr_ring_resize_multiple() to ptr_ring_resize_multiple_bh()
- skb_array_resize_multiple() to skb_array_resize_multiple_bh()

[PATCH OLK-6.6] NFS: Automounted filesystems should inherit ro,noexec,nodev,sync flags
by Wang Zhaolong 19 Jan '26
by Wang Zhaolong 19 Jan '26
19 Jan '26
From: Trond Myklebust <trond.myklebust(a)hammerspace.com>
stable inclusion
from stable-v6.6.120
commit dce10c59211e5cd763a62ea01e79b82a629811e3
category: bugfix
bugzilla: https://atomgit.com/src-openeuler/kernel/issues/13299
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id…
--------------------------------
[ Upstream commit 8675c69816e4276b979ff475ee5fac4688f80125 ]
When a filesystem is being automounted, it needs to preserve the
user-set superblock mount options, such as the "ro" flag.

[PATCH OLK-5.10] [Backport] HID: usbhid: Eliminate recurrent out-of-bounds bug in usbhid_parse()
by Chen Jinghuang 19 Jan '26
by Chen Jinghuang 19 Jan '26
19 Jan '26
From: Terry Junge <linuxhid(a)cosmicgizmosystems.com>
stable inclusion
from stable-v5.10.239
commit 41827a2dbdd7880df9881506dee13bc88d4230bb
category: bugfix
bugzilla: 9660
CVE: CVE-2025-38103
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id…
--------------------------------
commit fe7f7ac8e0c708446ff017453add769ffc15deed upstream.
Update struct hid_descriptor to better reflect the mandatory and
optional parts of the HID Descriptor as per USB HID 1.11 specification.
Note: the kernel currently does not parse any optional HID class
descriptors, only the mandatory report descriptor.
Update all references to member element desc[0] to rpt_desc.
Add test to verify bLength and bNumDescriptors values are valid.
Replace the for loop with direct access to the mandatory HID class
descriptor member for the report descriptor. This eliminates the
possibility of getting an out-of-bounds fault.
Add a warning message if the HID descriptor contains any unsupported
optional HID class descriptors.
Reported-by: syzbot+c52569baf0c843f35495(a)syzkaller.appspotmail.com
Closes: https://syzkaller.appspot.com/bug?extid=c52569baf0c843f35495

[PATCH openEuler-1.0-LTS] KVM: x86: Fix VM hard lockup after prolonged inactivity with periodic HV timer
by Zhang Kunbo 16 Jan '26
by Zhang Kunbo 16 Jan '26
16 Jan '26
From: fuqiang wang <fuqiang.wng(a)gmail.com>
commit 18ab3fc8e880791aa9f7c000261320fc812b5465 upstream.
When advancing the target expiration for the guest's APIC timer in periodic
mode, set the expiration to "now" if the target expiration is in the past
(similar to what is done in update_target_expiration()). Blindly adding
the period to the previous target expiration can result in KVM generating
a practically unbounded number of hrtimer IRQs due to programming an
expired timer over and over. In extreme scenarios, e.g. if userspace
pauses/suspends a VM for an extended duration, this can even cause hard
lockups in the host.
Currently, the bug only affects Intel CPUs when using the hypervisor timer
(HV timer), a.k.a. the VMX preemption timer. Unlike the software timer,
a.k.a. hrtimer, which KVM keeps running even on exits to userspace, the
HV timer only runs while the guest is active. As a result, if the vCPU
does not run for an extended duration, there will be a huge gap between
the target expiration and the current time the vCPU resumes running.
Because the target expiration is incremented by only one period on each
timer expiration, this leads to a series of timer expirations occurring
rapidly after the vCPU/VM resumes.
More critically, when the vCPU first triggers a periodic HV timer
expiration after resuming, advancing the expiration by only one period
will result in a target expiration in the past. As a result, the delta
may be calculated as a negative value. When the delta is converted into
an absolute value (tscdeadline is an unsigned u64), the resulting value
can overflow what the HV timer is capable of programming. I.e. the large
value will exceed the VMX Preemption Timer's maximum bit width of
cpu_preemption_timer_multi + 32, and thus cause KVM to switch from the
HV timer to the software timer (hrtimers).
After switching to the software timer, periodic timer expiration callbacks
may be executed consecutively within a single clock interrupt handler,
because hrtimers honors KVM's request for an expiration in the past and
immediately re-invokes KVM's callback after reprogramming. And because
the interrupt handler runs with IRQs disabled, restarting KVM's hrtimer
over and over until the target expiration is advanced to "now" can result
in a hard lockup.
E.g. the following hard lockup was triggered in the host when running a
Windows VM (only relevant because it used the APIC timer in periodic mode)
after resuming the VM from a long suspend (in the host).

Moreover, if the suspend duration of the virtual machine is not long enough
to trigger a hard lockup in this scenario, since commit 98c25ead5eda
("KVM: VMX: Move preemption timer <=> hrtimer dance to common x86"), KVM
will continue using the software timer until the guest reprograms the APIC
timer in some way. Since the periodic timer does not require frequent APIC
timer register programming, the guest may continue to use the software
timer in perpetuity.

Moreover, if the suspend duration of the virtual machine is not long enough
to trigger a hard lockup in this scenario, since commit 98c25ead5eda
("KVM: VMX: Move preemption timer <=> hrtimer dance to common x86"), KVM
will continue using the software timer until the guest reprograms the APIC
timer in some way. Since the periodic timer does not require frequent APIC
timer register programming, the guest may continue to use the software
timer in perpetuity.

[PATCH openEuler-1.0-LTS] scsi: libsas: Fix use-after-free bug in smp_execute_task_sg()

commit a9e5176ead6de64f572ad5c87a72825d9d3c82ae
category: bugfix
bugzilla: https://atomgit.com/src-openeuler/kernel/issues/8336
CVE: CVE-2022-50422
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id…
--------------------------------
[ Upstream commit 46ba53c30666717cb06c2b3c5d896301cd00d0c0 ]
When executing SMP task failed, the smp_execute_task_sg() calls del_timer()
to delete "slow_task->timer". However, if the timer handler
sas_task_internal_timedout() is running, the del_timer() in
smp_execute_task_sg() will not stop it and a UAF will happen. The process
is shown below:
(thread 1) | (thread 2)
smp_execute_task_sg() | sas_task_internal_timedout()
... |
del_timer() |
... | ...
sas_free_task(task) |
kfree(task->slow_task) //FREE|
| task->slow_task->... //USE
Fix by calling del_timer_sync() in smp_execute_task_sg(), which makes sure
the timer handler have finished before the "task->slow_task" is
deallocated.

--------------------------------
[ Upstream commit e4e46fb61e3bb4628170810d3f2b996b709b90d9 ]
mmc_add_host() may return error, if we ignore its return value,
it will lead two issues:
1. The memory that allocated in mmc_alloc_host() is leaked.
2. In the remove() path, mmc_remove_host() will be called to
delete device, but it's not added yet, it will lead a kernel
crash because of null-ptr-deref in device_del().
Fix this by checking the return value and goto error path which
will call mmc_free_host().

This series fixes kmemleak false warnings when reserving
crash kernel memory.
Patch 1 moves kmemleak_ignore_phys() to reserve_crashkernel_high()
where memory is actually tracked by kmemleak.
Patch 2 ensures kmemleak_ignore_phys() is only called when new memory
is allocated, not when crash_base is pre-set via cmdline.

Patch #1 introduces the OBJECT_PHYS flag and create_object_phys()
for physical address-allocated kmemleak objects.
Patch #2 adds object_phys_tree_root to store physical address objects
and uses raw physical addresses instead of virtual addresses.
Patch #3 fixes false positives in KFENCE by using kmemleak_ignore_phys()
for early memblock-allocated pools.
Patch #4 fixes similar false positives in percpu by replacing
kmemleak_free() with kmemleak_ignore_phys().
Patrick Wang (3):
mm: kmemleak: add OBJECT_PHYS flag for objects allocated with physical
address
mm: kmemleak: add rbtree and store physical address for objects
allocated with PA
mm: percpu: use kmemleak_ignore_phys() instead of kmemleak_free()
Yee Lee (1):
mm: kfence: apply kmemleak_ignore_phys on early allocated pool

+# XSched 用户指南
+
+## 1 环境部署
+
+### 1.1 安装 NPU 原生软件栈
+
+本特性依赖 NPU 原生软件栈，需要安装 NPU driver、firmware、CANN
+
+### 1.2 安装XSched内核
+
+#### 1.2.1 获取内核源码
+
+```bash
+# 下载源码
+git clone https://atomgit.com/openeuler/kernel.git -b OLK-6.6 OLK-6.6
+
+# 进入内核目录
+cd OLK-6.6
+```
+
+#### 1.2.2 安装内核
+
+##### 1.2.2.1 修改内核配置
+
+```shell
+# 生成默认配置
+make openeuler_defconfig
+
+# 修改并保存配置
+vim .config
+
+CONFIG_XCU_SCHEDULER=y
+CONFIG_XCU_VSTREAM=y
+CONFIG_XSCHED_NR_CUS=8 # 根据 NPU 卡的数量配置
+CONFIG_XCU_SCHED_RT=y
+CONFIG_XCU_SCHED_CFS=y
+CONFIG_CGROUP_XCU=y
+```
+
+##### 1.2.2.2 编译安装
+
+以下方式**二选一**：
+
+* 源码编译安装
+
+ ```bash
+ make clean && make -j$(nproc)
+ make modules_install -j$(nproc) INSTALL_MOD_STRIP=1 && INSTALL_MOD_STRIP=1 make install
+ grub2-set-default 0
+ ```
+
+* RPM 包编译安装
+
+ ```bash
+ INSTALL_MOD_STRIP=1 make rpm-pkg -j `nproc`
+ # kernel 和 devel 包都要安装，否则会导致驱动无法重编
+ rpm -ivh <path_to_rpm> --force
+ grub2-set-default 0
+ ```
+
+##### 1.2.2.3 修改 cmdline
+
+```shell
+# 修改内核引导文件，根据实际情况编辑
+vim /etc/grub2-efi.cfg
+
+# 在XSched内核新增 cmdline 配置，关闭驱动签名校验、开启cgroup-v2
+module.sig_enforce=0 systemd.unified_cgroup_hierarchy=1 cgroup_no_v1=all
+```
+
+保存引导文件后，重启切换内核
+
+### 1.3 重编驱动
+
+**！！需先安装好原生驱动！！**，`npu-smi info` 检查驱动是否安装成功
+
+#### 1.3.1 修改驱动
+
+获取驱动源码
+
+```shell
+mkdir <new_driver_dir>
+
+./Ascend-hdk-910b-npu-driver_xx.x.x_linux-aarch64.run --tar -xvf -C <new_driver_dir>
+```
+
+下载驱动补丁 [XSched driver patch](https://gitee.com/openeuler/kernel/commit/8d50448f11b697a177b63d3ccb… 适配 NPU 驱动
+
+```shell
+cp 0001-Adapt-910b-npu-driver-for-xsched.patch <new_driver_dir>/driver/kernel/
+cd <new_driver_dir>/driver/kernel/
+
+# 初始化 git 仓库并应用补丁
+git init
+git add .
+git commit -m "npu init"
+# 如果有冲突则根据 .rej 文件适配冲突代码
+git am 0001-Adapt-910b-npu-driver-for-xsched.patch --reject
+```
+
+#### 1.3.2 替换驱动
+
+```shell
+# 返回驱动根目录
+cd ../../
+
+# 备份原生驱动 ko
+cp -r <new_driver_dir>/driver/host <new_driver_dir>/driver/host-bak
+rm -f <new_driver_dir>/driver/host/*
+
+cd <new_driver_dir>/driver/script
+# 如果强制重编则增加 --force 参数，驱动 ko 会生成到 <new_driver_dir>/driver/host/
+sh run_driver_ko_rebuild.sh [--force]
+
+# 替换驱动
+for line in `ls /lib/modules/$(uname -r)/updates`; do \cp ../host/$line /lib/modules/$(uname -r)/updates; done
+```
+
+#### 1.3.3 检查驱动
+
+重启后检查驱动是否替换成功
+
+```shell
+reboot
+npu-smi info
+```
+
+### 1.4 libXSched
+
+XSched 用户态拦截层，拦截 CANN API 并转发到 XSched 内核
+
+#### 1.4.1 编译
+
+获取源码
+
+```bash
+git clone https://atomgit.com/openeuler/libXSched.git
+```
+
+编译源码
+
+```bash
+# 准备头文件
+cp OLK-6.6/include/uapi/linux/xsched/xcu_vstream.h /usr/include/linux
+
+# 编译生成 libucc_engine.so
+make clean && make
+```
+
+#### 1.4.2 使用
+
+使用 `LD_PRELOAD` 加载 `libucc_engine.so`
+
+```bash
+LD_PRELOAD=<path_to_libucc> <run_model_script>
+```
+
+### 1.5 验证
+
+```shell
+# 开启 XSched 日志
+echo "file kernel/xsched/* +p" > /sys/kernel/debug/dynamic_debug/control
+
+# pytorch 框架
+LD_PRELOAD=<path_to_libucc> python3 -c "import torch;import torch_npu; a = torch.randn(3, 4).npu(); print(a + a);"
+
+# mindspore 框架
+LD_PRELOAD=<path_to_libucc> python3 -c "import mindspore;mindspore.set_device('Ascend');mindspore.run_check()"
+```
+
+`dmesg` 查看内核日志，检查是否有 XSCHED 日志，有日志则说明 XSched 环境部署成功，验证完后关闭 XSched 日志 `echo "file kernel/xsched/* -p" > /sys/kernel/debug/dynamic_debug/control`
+
+## 2 使用指南
+
+### 2.1 Cgroup 接口
+
+#### 2.1.1 配置 XSched 策略
+
+使能 XSched 控制器
+
+```bash
+echo "+xcu" > /sys/fs/cgroup/cgroup.subtree_control
+```
+
+##### 2.1.1.1 可配置接口
+
+* `xcu.sched_class`：配置调度类，cfs 或 rt
+
+* `xcu.period_ms`：配置获取算力资源时间片周期，默认 100ms（需先设置为 cfs 调度类）
+
+* `xcu.quota_ms`：配置周期内可分配的时间片，比如配置 50ms，则每 100ms 内可分配 50ms，-1 则是不管控算力资源（需先设置为 cfs 调度类）
+
+* `xcu.shares`：配置 cfs 任务的权重，权重越大，相比于其他任务的优先级越高，默认为 1024（需先设置为 cfs 调度类）
+
+* `xcu.stat`：查看统计信息，仅支持 cfs 调度类
+
+##### 2.1.1.2 Host 使用方法
+
+在主机侧使用 XSched 管控 ai 任务，需手动创建 cgroup 组
+
+```bash
+mkdir -p /sys/fs/cgroup/xsched_group
+
+# 按需配置 XSched 策略，例如 echo cfs > /sys/fs/cgroup/xsched_group/xcu.sched_class
+echo <config_value> > /sys/fs/cgroup/xsched_group/xcu.<config_item>
+```
+
+将 ai 任务加入到 cgroup 中管控算力资源
+
+```bash
+# 运行 ai 任务
+LD_PRELOAD=<path_to_libucc> <run_model_script>
+
+# 加入 ai 任务到 cgroup
+echo <pid> > /sys/fs/cgroup/xsched_group/cgroup.procs
+```
+
+##### 2.1.1.3 Docker 使用方法
+
+启动 docker 容器时会自动挂载到 cgroup 目录（`/sys/fs/cgroup/user.slice`）下，docker 内的任务的 pid 也会自动添加到 cgroup.procs 下，无需手动创建 cgroup 组和添加任务
+
+1. 修改 docker 配置，修改挂载的 cgroup 目录和 docker 的 cgroup 版本为 v2（**docker 需升级到支持 cgroup-v2 的版本**）
+
+ ```bash
+ vim /etc/docker/daemon.json
+
+ # 添加以下配置
+ # 挂载的 cgroup 目录，目录名任意，以 docker.slice 为例
+ "cgroup-parent": "docker.slice"
+ # 使用 cgroup-v2 管理 docker
+ "exec-opts": ["native.cgroupdriver=systemd"]
+
+ # 修改保存后重启 docker 服务
+ systemctl restart docker
+ ```
+
+ 因为 docker 默认的挂载目录是 `/sys/fs/cgroup/user.slice` ，`user.slice` 下还会有其他的用户任务在运行，可能会无法修改 `user.slice` 的 XSched 配置，所以需要修改 docker 的挂载目录为 `/sys/fs/cgroup/docker.slice` 方便配置和管理
+
+2. 配置 docker 的 xsched 调度策略
+
+ ```bash
+ # 修改调度类为 cfs
+ echo cfs > /sys/fs/cgroup/docker.slice/xcu.sched_class
+
+ # 启动容器
+ docker start <container_name>
+
+ # 配置对应容器的 xsched 策略
+ echo <config_value> > /sys/fs/cgroup/docker.slice/docker-<docker_id>/xcu.<config_item>
+
+ # 进入容器
+ docker exec -it <container_name> bash
+
+ # 运行 ai 任务（容器内也有 libucc_engine.so），pid 会自动添加到 /sys/fs/cgroup/docker.slice/docker-<docker_id>/cgroup.procs
+ LD_PRELOAD=<path_to_libucc> <run_model_script>
+ ```
+
+### 2.2 Syscall 接口
+
+提供两个 syscall 接口用于设置/获取 rt 调度类的任务优先级（`xsched_setattr/xsched_getattr`）
+
+* `pid`：ai 任务 pid，pid=0 表示当前进程
+
+* `struct xsched_attr`：XSched 可配置属性
+
+ ```c
+ struct xsched_attr {
+ __u32 xsched_class; // 调度类，当前仅支持 RT（xsched_class=0）
+ __u32 xsched_priority; // rt 优先级，可配置范围 [1,5]，数字越大，优先级越高
+ };
+ ```
+
+调用 syscall 接口示例程序：
+
+```c
+#include <stdio.h>
+#include <stdlib.h>
+#include <unistd.h>
+#include <string.h>
+#include <errno.h>
+#include <sys/syscall.h>
+#include <stdint.h>
+#include <sys/types.h>
+
+// Define xsched_attr structure
+struct xsched_attr {
+ uint32_t xsched_class; // Scheduling class: XSCHED_TYPE_RT, XSCHED_TYPE_CFS
+ uint32_t xsched_priority; // Priority level: 1~5
+};
+
+// Scheduling class constants (should match kernel header definitions)
+#define XSCHED_TYPE_RT 0 // Real-time scheduling class
+#define XSCHED_TYPE_CFS 1 // Completely Fair Scheduler class
+
+// System call numbers (update these with actual numbers)
+#define __NR_xsched_setattr 467
+#define __NR_xsched_getattr 468
+
+// Wrapper functions for system calls
+static inline long xsched_setattr(pid_t pid, const struct xsched_attr *attr)
+{
+ return syscall(__NR_xsched_setattr, pid, attr);
+}
+
+static inline long xsched_getattr(pid_t pid, struct xsched_attr *attr)
+{
+ return syscall(__NR_xsched_getattr, pid, attr);
+}
+
+void main(void)
+{
+ pid_t pid = getpid();
+ struct xsched_attr attr;
+ long ret;
+
+ // Get current configuration
+ ret = xsched_getattr(pid, &attr);
+ if (ret < 0) {
+ printf("Failed to get configuration!\n");
+ }
+
+ attr.xsched_class = XSCHED_TYPE_RT;
+ attr.xsched_priority = 3;
+
+ ret = xsched_setattr(pid, &attr);
+ if (ret < 0) {
+ printf("Failed to set configuration\n");
+ }
+
+ // Verify the configuration
+ memset(&attr, 0, sizeof(attr));
+ ret = xsched_getattr(pid, &attr);
+ if (ret < 0) {
+ printf("Failed to verify configuration!\n");
+ }
+}
+```
+
+### 2.3 调试日志
+
+开启/关闭 XSched 调试日志
+
+```shell
+echo "file kernel/xsched/* +p" > /sys/kernel/debug/dynamic_debug/control
+echo "file kernel/xsched/* -p" > /sys/kernel/debug/dynamic_debug/control
+```
+
+开启/关闭 NPU 驱动调试日志
+
+```shell
+echo "module ascend_trs_core +p" > /sys/kernel/debug/dynamic_debug/control
+echo "module ascend_trs_pm_adapt +p" > /sys/kernel/debug/dynamic_debug/control
+echo "module ascend_trs_core -p" > /sys/kernel/debug/dynamic_debug/control
+echo "module ascend_trs_pm_adapt -p" > /sys/kernel/debug/dynamic_debug/control

----------------------------------------------------------------------
BPF supports creating high resolution timers using bpf_timer_* helper
functions. Currently, only the BPF_F_TIMER_ABS flag is supported, which
specifies that the timeout should be interpreted as absolute time. It
would also be useful to be able to pin that timer to a core. For
example, if you wanted to make a subset of cores run without timer
interrupts, and only have the timer be invoked on a single core.
This patch adds support for this with a new BPF_F_TIMER_CPU_PIN flag.
When specified, the HRTIMER_MODE_PINNED flag is passed to
hrtimer_start(). A subsequent patch will update selftests to validate.

--------------------------------
commit e8c73eb7db0a498cd4b22d2819e6ab1a6f506bd6 upstream.
The user calls fsconfig twice, but when the program exits, free() only
frees ctx->source for the second fsconfig, not the first.
Regarding fc->source, there is no code in the fs context related to its
memory reclamation.
To fix this memory leak, release the source memory corresponding to ctx
or fc before each parsing.

--------------------------------
commit 5c76f9961c170552c1d07c830b5e145475151600 upstream.
When smb2_query_info_compound() retries, a previously allocated cfid may
have been freed in the first attempt.
Because cfid wasn't reset on replay, later cleanup could act on a stale
pointer, leading to a potential use-after-free.
Reinitialize cfid to NULL under the replay label.
Example trace (trimmed):
refcount_t: underflow; use-after-free.

commit 868fc62811d3fabcf5685e14f36377a855d5412d
category: bugfix
bugzilla: https://atomgit.com/src-openeuler/kernel/issues/12582
CVE: CVE-2025-40268
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id…
--------------------------------
commit e8c73eb7db0a498cd4b22d2819e6ab1a6f506bd6 upstream.
The user calls fsconfig twice, but when the program exits, free() only
frees ctx->source for the second fsconfig, not the first.
Regarding fc->source, there is no code in the fs context related to its
memory reclamation.
To fix this memory leak, release the source memory corresponding to ctx
or fc before each parsing.

--------------------------------
Fix three refcount inconsistency issues related to `cifs_sb_tlink`.
Comments for `cifs_sb_tlink` state that `cifs_put_tlink()` needs to be
called after successful calls to `cifs_sb_tlink()`. Three calls fail to
update refcount accordingly, leading to possible resource leaks.

[PATCH OLK-6.6] ceph: fix race condition validating r_parent before applying state
by Wang Zhaolong 14 Jan '26
by Wang Zhaolong 14 Jan '26
14 Jan '26
From: Alex Markuze <amarkuze(a)redhat.com>
mainline inclusion
from mainline-v6.17-rc6
commit 15f519e9f883b316d86e2bb6b767a023aafd9d83
category: bugfix
bugzilla: https://atomgit.com/src-openeuler/kernel/issues/8352
CVE: CVE-2025-39927
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?…
--------------------------------
Add validation to ensure the cached parent directory inode matches the
directory info in MDS replies. This prevents client-side race conditions
where concurrent operations (e.g. rename) cause r_parent to become stale
between request initiation and reply processing, which could lead to
applying state changes to incorrect directory inodes.
[ idryomov: folded a kerneldoc fixup and a follow-up fix from Alex to
move CEPH_CAP_PIN reference when r_parent is updated:
When the parent directory lock is not held, req->r_parent can become
stale and is updated to point to the correct inode. However, the
associated CEPH_CAP_PIN reference was not being adjusted. The
CEPH_CAP_PIN is a reference on an inode that is tracked for
accounting purposes. Moving this pin is important to keep the
accounting balanced. When the pin was not moved from the old parent
to the new one, it created two problems: The reference on the old,
stale parent was never released, causing a reference leak.
A reference for the new parent was never acquired, creating the risk
of a reference underflow later in ceph_mdsc_release_request(). This
patch corrects the logic by releasing the pin from the old parent and
acquiring it for the new parent when r_parent is switched. This
ensures reference accounting stays balanced. ]

[PATCH OLK-6.6] ceph: fix race condition validating r_parent before applying state
by Wang Zhaolong 14 Jan '26
by Wang Zhaolong 14 Jan '26
14 Jan '26
From: Alex Markuze <amarkuze(a)redhat.com>
mainline inclusion
from mainline-v6.17-rc6
commit 15f519e9f883b316d86e2bb6b767a023aafd9d83
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/ID0R58
CVE: CVE-2025-39927
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?…
--------------------------------
Add validation to ensure the cached parent directory inode matches the
directory info in MDS replies. This prevents client-side race conditions
where concurrent operations (e.g. rename) cause r_parent to become stale
between request initiation and reply processing, which could lead to
applying state changes to incorrect directory inodes.
[ idryomov: folded a kerneldoc fixup and a follow-up fix from Alex to
move CEPH_CAP_PIN reference when r_parent is updated:
When the parent directory lock is not held, req->r_parent can become
stale and is updated to point to the correct inode. However, the
associated CEPH_CAP_PIN reference was not being adjusted. The
CEPH_CAP_PIN is a reference on an inode that is tracked for
accounting purposes. Moving this pin is important to keep the
accounting balanced. When the pin was not moved from the old parent
to the new one, it created two problems: The reference on the old,
stale parent was never released, causing a reference leak.
A reference for the new parent was never acquired, creating the risk
of a reference underflow later in ceph_mdsc_release_request(). This
patch corrects the logic by releasing the pin from the old parent and
acquiring it for the new parent when r_parent is switched. This
ensures reference accounting stays balanced. ]

In get_guest_rtc_ns(), "s->base_rtc" is uint64_t, which multiplied by
"NANOSECONDS_PER_SECOND" may overflow the uint64_t type, which will cause
the QEMU Linux Virtual Machine's time to jump and in turn triggers
a kernel Soft Lockup and ultimately leads to a crash.
Fix it by avoiding adding s->base_rtc in get_guest_rtc_ns_offset(),
because get_guest_rtc_ns() is used either take the remainder of
NANOSECONDS_PER_SECOND or take the quotient of NANOSECONDS_PER_SECOND.

category: bugfix
bugzilla: https://atomgit.com/src-openeuler/kernel/issues/9400
CVE: CVE-2025-38393
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id…
--------------------------------
We found a few different systems hung up in writeback waiting on the same
page lock, and one task waiting on the NFS_LAYOUT_DRAIN bit in
pnfs_update_layout(), however the pnfs_layout_hdr's plh_outstanding count
was zero.
It seems most likely that this is another race between the waiter and waker
similar to commit ed0172af5d6f ("SUNRPC: Fix a race to wake a sync task").
Fix it up by applying the advised barrier.
Fixes: 880265c77ac4 ("pNFS: Avoid a live lock condition in pnfs_update_layout()")

commit a7a8fe56e932a36f43e031b398aef92341bf5ea0 upstream.
There is a race condition in the readdir concurrency process, which may
access the rsp buffer after it has been released, triggering the
following KASAN warning.

--------------------------------
commit a7a8fe56e932a36f43e031b398aef92341bf5ea0 upstream.
There is a race condition in the readdir concurrency process, which may
access the rsp buffer after it has been released, triggering the
following KASAN warning.

[PATCH OLK-6.6] smb: client: Avoid race in open_cached_dir with lease breaks
by Wang Zhaolong 13 Jan '26

commit 3ca02e63edccb78ef3659bebc68579c7224a6ca2
category: bugfix
bugzilla: https://atomgit.com/src-openeuler/kernel/issues/10178
CVE: CVE-2025-37954
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?…
--------------------------------
A pre-existing valid cfid returned from find_or_create_cached_dir might
race with a lease break, meaning open_cached_dir doesn't consider it
valid, and thinks it's newly-constructed. This leaks a dentry reference
if the allocation occurs before the queued lease break work runs.
Avoid the race by extending holding the cfid_list_lock across
find_or_create_cached_dir and when the result is checked.

also involves closing any deferred close, waiting for outstanding I/O
to complete as well as marking all existing open handles as deleted to
prevent them from deferring closes, which increases the race window
for potential concurrent opens on the target file.
Fix this by unhashing the dentry in advance to prevent any concurrent
opens on the target.

[BUG]
A KASAN out-of-bounds issue was discovered during syzkaller testing:
BUG: unable to handle page fault for address: ffffed101c3f4de7 ...
......
Call Trace:
xfs_dir2_leaf_addname+0xc70/0x1060
xfs_dir_createname+0x3a6/0x4a0
xfs_create+0x6ff/0x8b0
......
[CAUSE]
The root cause is mounting a corrupted XFS image where the physical block
of a data block overlaps with the physical block of a leaf block. The
process is as follows:
1) User called getdents. Then xfs_readdir() is called to pre-read the
xfs_buf corresponding to the data block.
2) Then, when creating a file in the corresponding directory, the leaf
reuses the previous xfs_buf because of the same value of startblock and
blockcnt in record.
3) In xfs_dir2_leaf_addname(), "bestsp" is calculated by subtracting the
ltp->bestcount size from an address. At this point, bestcount is actually
xfs_dir2_data_unused->tag from the data block, which represents the offset
of the current unused space, making it easy to trigger an out-of-bounds
access on bestsp. Subsequent accesses to bestsp lead to this issue.
[FIX]
The xfs_dir3_leaf_read() function does not perform further validation on
the acquired xfs_buf. Following the logic in xfs_dir3_data_read() and
linux-mainline, apply the validation to leaf/leafn read to detect errors
early and prevent subsequent KASAN issues.

[ Upstream commit 0e629694126ca388916f059453a1c36adde219c4 ]
When using publicly available tools like 'mdio-tools' to read/write data
from/to network interface and its PHY via mdiobus, there is no verification of
parameters passed to the ioctl and it accepts any mdio address.
Currently there is support for 32 addresses in kernel via PHY_MAX_ADDR define,
but it is possible to pass higher value than that via ioctl.
While read/write operation should generally fail in this case,
mdiobus provides stats array, where wrong address may allow out-of-bounds
read/write.
Fix that by adding address verification before read/write operation.
While this excludes this access from any statistics, it improves security of
read/write operation.

--------------------------------
[ Upstream commit 0795b05a59b1371b18ffbf09d385296b12e9f5d5 ]
There is a potential crash issue when disabling and re-enabling the
network port. When disabling the network port, phy_detach() calls
device_link_del() to remove the device link, but it does not clear
phydev->devlink, so phydev->devlink is not a NULL pointer. Then the
network port is re-enabled, but if phy_attach_direct() fails before
calling device_link_add(), the code jumps to the "error" label and
calls phy_detach(). Since phydev->devlink retains the old value from
the previous attach/detach cycle, device_link_del() uses the old value,
which accesses a NULL pointer and causes a crash. The simplified crash
log is as follows.
[ 24.702421] Call trace:
[ 24.704856] device_link_put_kref+0x20/0x120
[ 24.709124] device_link_del+0x30/0x48

[ 24.725140] phylink_of_phy_connect+0x1c/0x34
Therefore, phydev->devlink needs to be cleared when the device link is
deleted.

When calculating the lookup table size, ensure the following

- NFT_PIPAPO_BUCKETS(f->bb) is 2^8, worst case.
- sizeof(unsigned long), from sizeof(*f->lt), lt in
struct nft_pipapo_field.
Then, use check_mul_overflow() to multiply by bucket size and then use
check_add_overflow() to the alignment for avx2 (if needed). Finally, add
lt_size_check_overflow() helper and use it to consolidate this.
While at it, replace leftover allocation using the GFP_KERNEL to
GFP_KERNEL_ACCOUNT for consistency, in pipapo_resize().

Digging into the source, context->notify_page may init by get_user_pages_fast
and can be seen in vmci_ctx_unset_notify which will try to put_page. However
get_user_pages_fast is not finished here and lead to following
try_grab_folio warning. The race condition is shown as follow:
cpu0 cpu1
vmci_host_do_set_notify
vmci_host_setup_notify
get_user_pages_fast(uva, 1, FOLL_WRITE, &context->notify_page);
lockless_pages_from_mm
gup_pgd_range
gup_huge_pmd // update &context->notify_page
vmci_host_do_set_notify
vmci_ctx_unset_notify
notify_page = context->notify_page;
if (notify_page)
put_page(notify_page); // page is freed
__gup_longterm_locked
__get_user_pages
follow_trans_huge_pmd
try_grab_folio // warn here
To slove this, use local variable page to make notify_page can be seen
after finish get_user_pages_fast.

If an error causes af_alg_sendmsg to abort, ctx->merge may contain
a garbage value from the previous loop. This may then trigger a
crash on the next entry into af_alg_sendmsg when it attempts to do
a merge that can't be done.
Fix this by setting ctx->merge to zero near the start of the loop.

[PATCH OLK-6.6] binfmt_misc: restore write access before closing files opened by open_exec()

--------------------------------
bm_register_write() opens an executable file using open_exec(), which
internally calls do_open_execat() and denies write access on the file to
avoid modification while it is being executed.
However, when an error occurs, bm_register_write() closes the file using
filp_close() directly. This does not restore the write permission, which
may cause subsequent write operations on the same file to fail.
Fix this by calling exe_file_allow_write_access() before filp_close() to
restore the write permission properly.

CVE: CVE-2025-68379
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id…
--------------------------------
A NULL pointer dereference can occur in rxe_srq_chk_attr() when
ibv_modify_srq() is invoked twice in succession under certain error
conditions. The first call may fail in rxe_queue_resize(), which leads
rxe_srq_from_attr() to set srq->rq.queue = NULL. The second call then
triggers a crash (null deref) when accessing
srq->rq.queue->buf->index_mask.

--------------------------------
[ Upstream commit 89bb613511cc21ed5ba6bddc1c9b9ae9c0dad392 ]
There is a potential race condition between sock bind and socket write
iter. bind may free the same cmd via mgmt_pending before write iter sends
the cmd, just as syzbot reported in UAF[1].
Here we use hci_dev_lock to synchronize the two, thereby avoiding the
UAF mentioned in [1].

[PATCH openEuler-1.0-LTS] tpm: tpm_tis: Add the missed acpi_put_table() to fix memory leak
by Gu Bowen 12 Jan '26

from stable-v4.19.270
commit de667a2704ae799f697fd45cf4317623d8c79fb7
category: bugfix
bugzilla: https://atomgit.com/src-openeuler/kernel/issues/13141
CVE: CVE-2022-50824
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id…
------------------
commit db9622f762104459ff87ecdf885cc42c18053fd9 upstream.
In check_acpi_tpm2(), we get the TPM2 table just to make
sure the table is there, not used after the init, so the
acpi_put_table() should be added to release the ACPI memory.
Fixes: 4cb586a188d4 ("tpm_tis: Consolidate the platform and acpi probe flow")

commit 5a3f3e39b18705bc578fae58abacc8ef93c15194
category: bugfix
bugzilla: https://atomgit.com/src-openeuler/kernel/issues/12614
CVE: CVE-2025-68297
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id…
--------------------------------
commit 43962db4a6f593903340c85591056a0cef812dfd upstream.
The crash in process_v2_sparse_read() for fscrypt-encrypted directories
has been reported. Issue takes place for Ceph msgr2 protocol in secure
mode. It can be reproduced by the steps:
sudo mount -t ceph :/ /mnt/cephfs/ -o name=admin,fs=cephfs,ms_mode=secure
(1) mkdir /mnt/cephfs/fscrypt-test-3
(2) cp area_decrypted.tar /mnt/cephfs/fscrypt-test-3
(3) fscrypt encrypt --source=raw_key --key=./my.key /mnt/cephfs/fscrypt-test-3
(4) fscrypt lock /mnt/cephfs/fscrypt-test-3
(5) fscrypt unlock --key=my.key /mnt/cephfs/fscrypt-test-3
(6) cat /mnt/cephfs/fscrypt-test-3/area_decrypted.tar
(7) Issue has been triggered

==================================================================
First of all, we have warning in get_bvec_at() because
cursor->total_resid contains zero value. And, finally,
we have crash in ceph_msg_data_advance() because
cursor->data is NULL. It means that get_bvec_at()
receives not initialized ceph_msg_data_cursor structure
because data is NULL and total_resid contains zero.
Moreover, we don't have likewise issue for the case of
Ceph msgr1 protocol because ceph_msg_data_cursor_init()
has been called before reading sparse data.
This patch adds calling of ceph_msg_data_cursor_init()
in the beginning of process_v2_sparse_read() with
the goal to guarantee that logic of reading sparse data
works correctly for the case of Ceph msgr2 protocol.

[ Upstream commit 5ffcb7b890f61541201461580bb6622ace405aec ]
The atlantic driver can receive packets with more than MAX_SKB_FRAGS (17)
fragments when handling large multi-descriptor packets. This causes an
out-of-bounds write in skb_add_rx_frag_netmem() leading to kernel panic.
The issue occurs because the driver doesn't check the total number of
fragments before calling skb_add_rx_frag(). When a packet requires more
than MAX_SKB_FRAGS fragments, the fragment index exceeds the array bounds.
Fix by assuming there will be an extra frag if buff->len > AQ_CFG_RX_HDR_SIZE,
then all fragments are accounted for. And reusing the existing check to
prevent the overflow earlier in the code path.
This crash occurred in production with an Aquantia AQC113 10G NIC.

[ Upstream commit 09b0cd1297b4dbfe736aeaa0ceeab2265f47f772 ]
hci_cmd_sync_dequeue_once() does lookup and then cancel
the entry under two separate lock sections. Meanwhile,
hci_cmd_sync_work() can also delete the same entry,
leading to double list_del() and "UAF".
Fix this by holding cmd_sync_work_lock across both
lookup and cancel, so that the entry cannot be removed
concurrently.

--------------------------------
The sit driver's packet transmission path calls: sit_tunnel_xmit() ->
update_or_create_fnhe(), which lead to fnhe_remove_oldest() being called
to delete entries exceeding FNHE_RECLAIM_DEPTH+random.
The race window is between fnhe_remove_oldest() selecting fnheX for
deletion and the subsequent kfree_rcu(). During this time, the
concurrent path's __mkroute_output() -> find_exception() can fetch the
soon-to-be-deleted fnheX, and rt_bind_exception() then binds it with a
new dst using a dst_hold(). When the original fnheX is freed via RCU,
the dst reference remains permanently leaked.
CPU 0 CPU 1
__mkroute_output()
find_exception() [fnheX]
update_or_create_fnhe()
fnhe_remove_oldest() [fnheX]
rt_bind_exception() [bind dst]
RCU callback [fnheX freed, dst leak]
This issue manifests as a device reference count leak and a warning in
dmesg when unregistering the net device:
unregister_netdevice: waiting for sitX to become free. Usage count = N
Ido Schimmel provided the simple test validation method [1].
The fix clears 'oldest->fnhe_daddr' before calling fnhe_flush_routes().
Since rt_bind_exception() checks this field, setting it to zero prevents
the stale fnhe from being reused and bound to a new dst just before it
is freed.

put_bh
--> trigger stack-out-of-bounds
In the mpage_read_folio() function, the stack variable 'map_bh' is
passed to ntfs_get_block_vbo(). Once unlock_buffer() unlocks and
wait_on_buffer() returns to continue processing, the stack variable
is likely to be reclaimed. Consequently, during the end_buffer_read_sync()
process, calling put_bh() may result in stack overrun.
If the bh is not allocated on the stack, it belongs to a folio. Freeing
a buffer head which belongs to a folio is done by drop_buffers() which
will fail to free buffers which are still locked. So it is safe to call
put_bh() before __end_buffer_read_notouch().

[PATCH openEuler-1.0-LTS] [Huawei] sched/rt: Skip currently executing CPU in rto_next_cpu()

--------------------------------
CPU0 becomes overloaded when hosting a CPU-bound RT task, a non-CPU-bound
RT task, and a CFS task stuck in kernel space. When other CPUs switch from
RT to non-RT tasks, RT load balancing (LB) is triggered; with
HAVE_RT_PUSH_IPI enabled, they send IPIs to CPU0 to drive the execution
of rto_push_irq_work_func. During push_rt_task on CPU0,
if next_task->prio < rq->donor->prio, resched_curr() sets NEED_RESCHED
and after the push operation completes, CPU0 calls rto_next_cpu().
Since only CPU0 is overloaded in this scenario, rto_next_cpu() should
ideally return -1 (no further IPI needed).
However, multiple CPUs invoking tell_cpu_to_push() during LB increments
rd->rto_loop_next. Even when rd->rto_cpu is set to -1, the mismatch between
rd->rto_loop and rd->rto_loop_next forces rto_next_cpu() to restart its
search from -1. With CPU0 remaining overloaded (satisfying rt_nr_migratory
&& rt_nr_total > 1), it gets reselected, causing CPU0 to queue irq_work to
itself and send self-IPIs repeatedly. As long as CPU0 stays overloaded and
other CPUs run pull_rt_tasks(), it falls into an infinite self-IPI loop,
which triggers a CPU hardlockup due to continuous self-interrupts.
The trigging scenario is as follows:
cpu0 cpu1 cpu2
pull_rt_task
tell_cpu_to_push
<------------irq_work_queue_on
rto_push_irq_work_func
push_rt_task
resched_curr(rq) pull_rt_task
rto_next_cpu tell_cpu_to_push
<-------------------------- atomic_inc(rto_loop_next)
rd->rto_loop != next
rto_next_cpu
irq_work_queue_on
rto_push_irq_work_func
Fix redundant self-IPI by filtering the initiating CPU in rto_next_cpu().
This solution has been verified to effectively eliminate spurious self-IPIs
and prevent CPU hardlockup scenarios.

----------------------------------------------------------------------
A bitmap inconsistency issue was observed during stress tests under
mixed huge-page workloads. Ext4 reported multiple e4b bitmap check
failures like:
ext4_mb_complex_scan_group:2508: group 350, 8179 free clusters as
per group info. But got 8192 blocks
Analysis and experimentation confirmed that the issue is caused by a
race condition between page migration and bitmap modification. Although
this timing window is extremely narrow, it is still hit in practice:
folio_lock ext4_mb_load_buddy
__migrate_folio
check ref count
folio_mc_copy __filemap_get_folio
folio_try_get(folio)
......
mb_mark_used
ext4_mb_unload_buddy
__folio_migrate_mapping
folio_ref_freeze
folio_unlock
The root cause of this issue is that the fast path of load_buddy only
increments the folio's reference count, which is insufficient to prevent
concurrent folio migration. We observed that the folio migration process
acquires the folio lock. Therefore, we can determine whether to take the
fast path in load_buddy by checking the lock status. If the folio is
locked, we opt for the slow path (which acquires the lock) to close this
concurrency window.
Additionally, this change addresses the following issues:
When the DOUBLE_CHECK macro is enabled to inspect bitmap-related
issues, the following error may be triggered:
corruption in group 324 at byte 784(6272): f in copy != ff on
disk/prealloc
Analysis reveals that this is a false positive. There is a specific race
window where the bitmap and the group descriptor become momentarily
inconsistent, leading to this error report:
ext4_mb_load_buddy ext4_mb_load_buddy
__filemap_get_folio(create|lock)
folio_lock
ext4_mb_init_cache
folio_mark_uptodate
__filemap_get_folio(no lock)
......
mb_mark_used
mb_mark_used_double
mb_cmp_bitmaps
mb_set_bits(e4b->bd_bitmap)
folio_unlock
The original logic assumed that since mb_cmp_bitmaps is called when the
bitmap is newly loaded from disk, the folio lock would be sufficient to
prevent concurrent access. However, this overlooks a specific race
condition: if another process attempts to load buddy and finds the folio
is already in an uptodate state, it will immediately begin using it without
holding folio lock.

[PATCH OLK-6.6] kernfs: Don't re-lock kernfs_root::kernfs_rwsem in kernfs_fop_readdir().

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?…
--------------------------------
The readdir operation iterates over all entries and invokes dir_emit()
for every entry passing kernfs_node::name as argument.
Since the name argument can change, and become invalid, the
kernfs_root::kernfs_rwsem lock should not be dropped to prevent renames
during the operation.
The lock drop around dir_emit() has been initially introduced in commit
1e5289c97bba2 ("sysfs: Cache the last sysfs_dirent to improve readdir scalability v2")
to avoid holding a global lock during a page fault. The lock drop is
wrong since the support of renames and not a big burden since the lock
is no longer global.
Don't re-acquire kernfs_root::kernfs_rwsem while copying the name to the
userpace buffer.

--------------------------------
commit ae668cd567a6a7622bc813ee0bb61c42bed61ba7 upstream.
ENODATA (aka ENOATTR) has a very specific meaning in the xfs xattr code;
namely, that the requested attribute name could not be found.
However, a medium error from disk may also return ENODATA. At best,
this medium error may escape to userspace as "attribute not found"
when in fact it's an IO (disk) error.
At worst, we may oops in xfs_attr_leaf_get() when we do:
error = xfs_attr_leaf_hasname(args, &bp);
if (error == -ENOATTR) {
xfs_trans_brelse(args->trans, bp);
return error;
}
because an ENODATA/ENOATTR error from disk leaves us with a null bp,
and the xfs_trans_brelse will then null-deref it.
As discussed on the list, we really need to modify the lower level
IO functions to trap all disk errors and ensure that we don't let
unique errors like this leak up into higher xfs functions - many
like this should be remapped to EIO.
However, this patch directly addresses a reported bug in the xattr
code, and should be safe to backport to stable kernels. A larger-scope
patch to handle more unique errors at lower levels can follow later.
(Note, prior to 07120f1abdff we did not oops, but we did return the
wrong error code to userspace.)

LeapIO inclusion
category: feature
bugzilla: https://atomgit.com/openeuler/kernel/issues/8340
------------------------------------------
The LeapRAID driver provides support for LeapRAID PCIe RAID controllers,
enabling communication between the host operating system, firmware, and
hardware for efficient storage management.
The main source files are organized as follows:
leapraid_os.c:
Implements the scsi_host_template functions, PCIe device probing, and
initialization routines, integrating the driver with the Linux SCSI
subsystem.
leapraid_func.c:
Provides the core functional routines that handle low-level interactions
with the controller firmware and hardware, including interrupt handling,
topology management, and reset sequence processing, and other related
operations.
leapraid_app.c:
Implements the ioctl interface, providing user-space tools access to device
management and diagnostic operations.
leapraid_transport.c:
Interacts with the Linux SCSI transport layer to add SAS phys and ports.
leapraid_func.h:
Declares common data structures, constants, and function prototypes shared
across the driver.
leapraid.h:
Provides global constants, register mappings, and interface definitions
that facilitate communication between the driver and the controller
firmware.
The leapraid_probe function is called when the driver detects a supported
LeapRAID PCIe device. It allocates and initializes the Scsi_Host structure,
configures hardware and firmware interfaces, and registers the host adapter
with the Linux SCSI mid-layer.
After registration, the driver invokes scsi_scan_host() to initiate device
discovery. The firmware then reports discovered logical and physical
devices to the host through interrupt-driven events and synchronizes their
operational states.
leapraid_adapter is the core data structure that encapsulates all resources
and runtime state information maintained during driver operation, described
as follows:
/**
* struct leapraid_adapter - Main LeapRaid adapter structure
* @list: List head for adapter management
* @shost: SCSI host structure
* @pdev: PCI device structure
* @iomem_base: I/O memory mapped base address
* @rep_msg_host_idx: Host index for reply messages
* @mask_int: Interrupt masking flag
* @timestamp_sync_cnt: Timestamp synchronization counter
* @adapter_attr: Adapter attributes
* @mem_desc: Memory descriptor
* @driver_cmds: Driver commands
* @dynamic_task_desc: Dynamic task descriptor
* @fw_evt_s: Firmware event structure
* @notification_desc: Notification descriptor
* @reset_desc: Reset descriptor
* @scan_dev_desc: Device scan descriptor
* @access_ctrl: Access control
* @fw_log_desc: Firmware log descriptor
* @dev_topo: Device topology
* @boot_devs: Boot devices
* @smart_poll_desc: SMART polling descriptor
*/

------------------------------------------
The LeapRAID driver provides support for LeapRAID PCIe RAID controllers,
enabling communication between the host operating system, firmware, and
hardware for efficient storage management.
The main source files are organized as follows:
leapraid_os.c:
Implements the scsi_host_template functions, PCIe device probing, and
initialization routines, integrating the driver with the Linux SCSI
subsystem.
leapraid_func.c:
Provides the core functional routines that handle low-level interactions
with the controller firmware and hardware, including interrupt handling,
topology management, and reset sequence processing, and other related
operations.
leapraid_app.c:
Implements the ioctl interface, providing user-space tools access to device
management and diagnostic operations.
leapraid_transport.c:
Interacts with the Linux SCSI transport layer to add SAS phys and ports.
leapraid_func.h:
Declares common data structures, constants, and function prototypes shared
across the driver.
leapraid.h:
Provides global constants, register mappings, and interface definitions
that facilitate communication between the driver and the controller
firmware.
The leapraid_probe function is called when the driver detects a supported
LeapRAID PCIe device. It allocates and initializes the Scsi_Host structure,
configures hardware and firmware interfaces, and registers the host adapter
with the Linux SCSI mid-layer.
After registration, the driver invokes scsi_scan_host() to initiate device
discovery. The firmware then reports discovered logical and physical
devices to the host through interrupt-driven events and synchronizes their
operational states.
leapraid_adapter is the core data structure that encapsulates all resources
and runtime state information maintained during driver operation, described
as follows:
/**
* struct leapraid_adapter - Main LeapRaid adapter structure
* @list: List head for adapter management

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id…
--------------------------------
[ Upstream commit 56b3c85e153b84f27e6cff39623ba40a1ad299d3 ]
When livepatch is attached to the same function as bpf trampoline with
a fexit program, bpf trampoline code calls register_ftrace_direct()
twice. The first time will fail with -EAGAIN, and the second time it
will succeed. This requires register_ftrace_direct() to unregister
the address on the first attempt. Otherwise, the bpf trampoline cannot
attach. Here is an easy way to reproduce this issue:
insmod samples/livepatch/livepatch-sample.ko
bpftrace -e 'fexit:cmdline_proc_show {}'
ERROR: Unable to attach probe: fexit:vmlinux:cmdline_proc_show...
Fix this by cleaning up the hash when register_ftrace_function_nolock hits
errors.
Also, move the code that resets ops->func and ops->trampoline to the error
path of register_ftrace_direct(); and add a helper function reset_direct()
in register_ftrace_direct() and unregister_ftrace_direct().

--------------------------------
[ Upstream commit c15859bfd326c10230f09cb48a17f8a35f190342 ]
It willl cause null-ptr-deref in the following case:
uif_init()
ubi_add_volume()
cdev_add() -> if it fails, call kill_volumes()
device_register()
kill_volumes() -> if ubi_add_volume() fails call this function
ubi_free_volume()
cdev_del()
device_unregister() -> trying to delete a not added device,
it causes null-ptr-deref
So in ubi_free_volume(), it delete devices whether they are added
or not, it will causes null-ptr-deref.
Handle the error case whlie calling ubi_add_volume() to fix this
problem. If add volume fails, set the corresponding vol to null,
so it can not be accessed in kill_volumes() and release the
resource in ubi_add_volume() error path.

bugzilla: https://atomgit.com/openeuler/kernel/issues/8333
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id…
--------------------------------
[ Upstream commit 781802aa5a5950f99899f13ff9d760f5db81d36d ]
Function ip_rfc1001_connect() which establish NetBIOS session for SMB
connections, currently uses smb_send() function for sending NetBIOS Session
Request packet. This function expects that the passed buffer is SMB packet
and for SMB2+ connections it mangles packet header, which breaks prepared
NetBIOS Session Request packet. Result is that this function send garbage
packet for SMB2+ connection, which SMB2+ server cannot parse. That function
is not mangling packets for SMB1 connections, so it somehow works for SMB1.
Fix this problem and instead of smb_send(), use smb_send_kvec() function
which does not mangle prepared packet, this function send them as is. Just
API of this function takes struct msghdr (kvec) instead of packet buffer.
[MS-SMB2] specification allows SMB2 protocol to use NetBIOS as a transport
protocol. NetBIOS can be used over TCP via port 139. So this is a valid
configuration, just not so common. And even recent Windows versions (e.g.
Windows Server 2022) still supports this configuration: SMB over TCP port
139, including for modern SMB2 and SMB3 dialects.
This change fixes SMB2 and SMB3 connections over TCP port 139 which
requires establishing of NetBIOS session. Tested that this change fixes
establishing of SMB2 and SMB3 connections with Windows Server 2022.

Backport the following patches for OLK-5.10:
- e14f9d96acb7 mm/memory-failure: support disabling soft offline for HugeTLB pages
- 2f0c01a690d1 mm/memory-failure: userspace controls soft-offlining pages
- 9bb3fd60f91e arm64: mm: Add copy mc support for all migrate_page
- 45dbef4c04f6 mm: page_eject: Add mc support during offline page
- b7f5b9ef641a mm: Update PF_COREDUMP_MCS to PF_MCS
- 17d08829674a mm/hwpoison: add migrate_page_mc_extra()
- c10a520c4102 mm/hwpoison: introduce copy_mc_highpages
- d689cd1c1479 mm/hwpoison: arm64: introduce copy_mc_highpage
Add mcs support for migrate page & support disabling soft offline for
HugeTLB pages.
Since UCE kernel recovery is needed by this. This should be enable
with the following step:
- echo 1 > /proc/sys/kernel/uce_kernel_recovery
Disable soft offline support for hugetlb with the following step:
- echo 3 > /proc/sys/vm/enable_soft_offline
Since ARCH_ENABLE_HUGEPAGE_MIGRATION is not enabled in openeuler_defconfig
in arm64. There is no need to merge soft-offining related patches.

--------------------------------
When having a multiuser mount with domain= specified and using
cifscreds, cifs_set_cifscreds() will end up setting @ctx->domainname,
so it needs to be freed before leaving cifs_construct_tcon().
This fixes the following memory leak reported by kmemleak:
mount.cifs //srv/share /mnt -o domain=ZELDA,multiuser,...
su - testuser
cifscreds add -d ZELDA -u testuser

[PATCH OLK-6.6] cifs: fix memory leak in smb3_fs_context_parse_param error path

commit 7627864dc3121f39e220f5253a227edf472de59e
category: bugfix
bugzilla: https://atomgit.com/src-openeuler/kernel/issues/11561
CVE: CVE-2025-68219
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id…
--------------------------------
[ Upstream commit 7e4d9120cfa413dd34f4f434befc5dbe6c38b2e5 ]
Add proper cleanup of ctx->source and fc->source to the
cifs_parse_mount_err error handler. This ensures that memory allocated
for the source strings is correctly freed on all error paths, matching
the cleanup already performed in the success path by
smb3_cleanup_fs_context_contents().
Pointers are also set to NULL after freeing to prevent potential
double-free issues.
This change fixes a memory leak originally detected by syzbot. The
leak occurred when processing Opt_source mount options if an error
happened after ctx->source and fc->source were successfully
allocated but before the function completed.
The specific leak sequence was:
1. ctx->source = smb3_fs_context_fullpath(ctx, '/') allocates memory
2. fc->source = kstrdup(ctx->source, GFP_KERNEL) allocates more memory
3. A subsequent error jumps to cifs_parse_mount_err
4. The old error handler freed passwords but not the source strings,
causing the memory to leak.
This issue was not addressed by commit e8c73eb7db0a ("cifs: client:
fix memory leak in smb3_fs_context_parse_param"), which only fixed
leaks from repeated fsconfig() calls but not this error path.
Patch updated with minor change suggested by kernel test robot

--------------------------------
commit 5c76f9961c170552c1d07c830b5e145475151600 upstream.
When smb2_query_info_compound() retries, a previously allocated cfid may
have been freed in the first attempt.
Because cfid wasn't reset on replay, later cleanup could act on a stale
pointer, leading to a potential use-after-free.
Reinitialize cfid to NULL under the replay label.
Example trace (trimmed):
refcount_t: underflow; use-after-free.

--------------------------------
commit e8c73eb7db0a498cd4b22d2819e6ab1a6f506bd6 upstream.
The user calls fsconfig twice, but when the program exits, free() only
frees ctx->source for the second fsconfig, not the first.
Regarding fc->source, there is no code in the fs context related to its
memory reclamation.
To fix this memory leak, release the source memory corresponding to ctx
or fc before each parsing.

--------------------------------
[ Upstream commit 49c8d2c1f94cc2f4d1a108530d7ba52614b874c2 ]
commit efa95b01da18 ("netpoll: fix use after free") incorrectly
ignored the refcount and prematurely set dev->npinfo to NULL during
netpoll cleanup, leading to improper behavior and memory leaks.
Scenario causing lack of proper cleanup:
1) A netpoll is associated with a NIC (e.g., eth0) and netdev->npinfo is
allocated, and refcnt = 1
- Keep in mind that npinfo is shared among all netpoll instances. In
this case, there is just one.
2) Another netpoll is also associated with the same NIC and
npinfo->refcnt += 1.
- Now dev->npinfo->refcnt = 2;
- There is just one npinfo associated to the netdev.
3) When the first netpolls goes to clean up:
- The first cleanup succeeds and clears np->dev->npinfo, ignoring
refcnt.
- It basically calls `RCU_INIT_POINTER(np->dev->npinfo, NULL);`
- Set dev->npinfo = NULL, without proper cleanup
- No ->ndo_netpoll_cleanup() is either called
4) Now the second target tries to clean up
- The second cleanup fails because np->dev->npinfo is already NULL.
* In this case, ops->ndo_netpoll_cleanup() was never called, and
the skb pool is not cleaned as well (for the second netpoll
instance)
- This leaks npinfo and skbpool skbs, which is clearly reported by
kmemleak.
Revert commit efa95b01da18 ("netpoll: fix use after free") and adds
clarifying comments emphasizing that npinfo cleanup should only happen
once the refcount reaches zero, ensuring stable and correct netpoll
behavior.

[PATCH OLK-6.6] net: netpoll: fix incorrect refcount handling causing incorrect cleanup

category: bugfix
bugzilla: https://atomgit.com/src-openeuler/kernel/issues/11539
CVE: CVE-2025-68245
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id…
--------------------------------
[ Upstream commit 49c8d2c1f94cc2f4d1a108530d7ba52614b874c2 ]
commit efa95b01da18 ("netpoll: fix use after free") incorrectly
ignored the refcount and prematurely set dev->npinfo to NULL during
netpoll cleanup, leading to improper behavior and memory leaks.
Scenario causing lack of proper cleanup:
1) A netpoll is associated with a NIC (e.g., eth0) and netdev->npinfo is
allocated, and refcnt = 1
- Keep in mind that npinfo is shared among all netpoll instances. In
this case, there is just one.
2) Another netpoll is also associated with the same NIC and
npinfo->refcnt += 1.
- Now dev->npinfo->refcnt = 2;
- There is just one npinfo associated to the netdev.
3) When the first netpolls goes to clean up:
- The first cleanup succeeds and clears np->dev->npinfo, ignoring
refcnt.
- It basically calls `RCU_INIT_POINTER(np->dev->npinfo, NULL);`
- Set dev->npinfo = NULL, without proper cleanup
- No ->ndo_netpoll_cleanup() is either called
4) Now the second target tries to clean up
- The second cleanup fails because np->dev->npinfo is already NULL.
* In this case, ops->ndo_netpoll_cleanup() was never called, and
the skb pool is not cleaned as well (for the second netpoll
instance)
- This leaks npinfo and skbpool skbs, which is clearly reported by
kmemleak.
Revert commit efa95b01da18 ("netpoll: fix use after free") and adds
clarifying comments emphasizing that npinfo cleanup should only happen
once the refcount reaches zero, ensuring stable and correct netpoll
behavior.

--------------------------------
commit ac1499fcd40fe06479e9b933347b837ccabc2a40 upstream.
The sit driver's packet transmission path calls: sit_tunnel_xmit() ->
update_or_create_fnhe(), which lead to fnhe_remove_oldest() being called
to delete entries exceeding FNHE_RECLAIM_DEPTH+random.
The race window is between fnhe_remove_oldest() selecting fnheX for
deletion and the subsequent kfree_rcu(). During this time, the
concurrent path's __mkroute_output() -> find_exception() can fetch the
soon-to-be-deleted fnheX, and rt_bind_exception() then binds it with a
new dst using a dst_hold(). When the original fnheX is freed via RCU,
the dst reference remains permanently leaked.
CPU 0 CPU 1
__mkroute_output()
find_exception() [fnheX]
update_or_create_fnhe()
fnhe_remove_oldest() [fnheX]
rt_bind_exception() [bind dst]
RCU callback [fnheX freed, dst leak]
This issue manifests as a device reference count leak and a warning in
dmesg when unregistering the net device:
unregister_netdevice: waiting for sitX to become free. Usage count = N
Ido Schimmel provided the simple test validation method [1].
The fix clears 'oldest->fnhe_daddr' before calling fnhe_flush_routes().
Since rt_bind_exception() checks this field, setting it to zero prevents
the stale fnhe from being reused and bound to a new dst just before it
is freed.

[ Upstream commit 2327a3d6f65ce2fe2634546dde4a25ef52296fec ]
Fix field-spanning memcpy warnings in ah6_output() and
ah6_output_done() where extension headers are copied to/from IPv6
address fields, triggering fortify-string warnings about writes beyond
the 16-byte address fields.
memcpy: detected field-spanning write (size 40) of single field "&top_iph->saddr" at net/ipv6/ah6.c:439 (size 16)
WARNING: CPU: 0 PID: 8838 at net/ipv6/ah6.c:439 ah6_output+0xe7e/0x14e0 net/ipv6/ah6.c:439
The warnings are false positives as the extension headers are
intentionally placed after the IPv6 header in memory. Fix by properly
copying addresses and extension headers separately, and introduce
helper functions to avoid code duplication.

[PATCH OLK-6.6] Revert "NFS: fix up nfs_release_folio() to try to release the page"

------------------
This reverts commit 96780ca55e3cbf4f150fd5a833a61492c9947b5b.
Under the following scenario, using NFSv4.1 may lead to deadlock caused
by circular waiting.
The scenario is:
- NFSv4.1 client running heavy multi-threaded buffered I/O (fio-style
workload)
- server outage (restart/power-off) and/or network blackhole
- client under significant memory pressure / reclaim activity (observed in
the traces below)
The observed behavior is a deadlock cycle involving:
- v4.1 session slot table “draining” (NFS4_SLOT_TBL_DRAINING)
- state manager thread creation via kthread_run()
- kthreadd entering direct reclaim and getting stuck in NFS
commit/writeback paths
- non-privileged RPC tasks sleeping on slot table waitq due to draining
This issue has already been discussed within the upstream. Before a formal
fix is developed, it is suggested to revert back the patch that introduced
the problem to prevent it from occurring.[1]
In addition, this revert patch conflicts with 98ab188dbab3 ("[Backport]
NFS: fix nfs release_folio() to not deadlock via kcompactd writeback");
please be aware of this when performing subsequent rollbacks.

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id…
--------------------------------
[ Upstream commit dc2f650f7e6857bf384069c1a56b2937a1ee370d ]
netdev_WARN() uses WARN/WARN_ON to print a backtrace along with
file and line information. In this case, udp_tunnel_nic_register()
returning an error is just a failed operation, not a kernel bug.
udp_tunnel_nic_register() can fail due to a memory allocation
failure (kzalloc() or udp_tunnel_nic_alloc()).
This is a normal runtime error and not a kernel bug.
Replace netdev_WARN() with netdev_warn() accordingly.

[PATCH OLK-6.6] Bluetooth: hci_core: lookup hci_conn on RX path on protocol side

commit 79a2d4678ba90bdba577dc3af88cc900d6dcd5ee
category: bugfix
bugzilla: https://atomgit.com/src-openeuler/kernel/issues/13304
CVE: CVE-2025-68304
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?…
--------------------------------
The hdev lock/lookup/unlock/use pattern in the packet RX path doesn't
ensure hci_conn* is not concurrently modified/deleted. This locking
appears to be leftover from before conn_hash started using RCU
commit bf4c63252490b ("Bluetooth: convert conn hash to RCU")
and not clear if it had purpose since then.
Currently, there are code paths that delete hci_conn* from elsewhere
than the ordered hdev->workqueue where the RX work runs in. E.g.
commit 5af1f84ed13a ("Bluetooth: hci_sync: Fix UAF on hci_abort_conn_sync")
introduced some of these, and there probably were a few others before
it. It's better to do the locking so that even if these run
concurrently no UAF is possible.
Move the lookup of hci_conn and associated socket-specific conn to
protocol recv handlers, and do them within a single critical section
to cover hci_conn* usage and lookup.
syzkaller has reported a crash that appears to be this issue:
[Task hdev->workqueue] [Task 2]
hci_disconnect_all_sync
l2cap_recv_acldata(hcon)
hci_conn_get(hcon)
hci_abort_conn_sync(hcon)
hci_dev_lock
hci_dev_lock
hci_conn_del(hcon)
v-------------------------------- hci_dev_unlock
hci_conn_put(hcon)
conn = hcon->l2cap_data (UAF)

[PATCH openEuler-1.0-LTS] acct: fix potential integer overflow in encode_comp_t()

stable inclusion

commit 1750a0983c455a9b3badd848471fc8d58cb61f67
category: bugfix
bugzilla: https://atomgit.com/src-openeuler/kernel/issues/12905
CVE: CVE-2022-50749
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id…
--------------------------------
[ Upstream commit c5f31c655bcc01b6da53b836ac951c1556245305 ]
The integer overflow is descripted with following codes:
> 317 static comp_t encode_comp_t(u64 value)
> 318 {
> 319 int exp, rnd;
......
> 341 exp <<= MANTSIZE;
> 342 exp += value;
> 343 return exp;
> 344 }
Currently comp_t is defined as type of '__u16', but the variable 'exp' is
type of 'int', so overflow would happen when variable 'exp' in line 343 is
greater than 65535.

--------------------------------
regulator_supply_alias_list was accessed without any locking in
regulator_supply_alias(), regulator_register_supply_alias(), and
regulator_unregister_supply_alias(). Concurrent registration,
unregistration and lookups can race, leading to:
1 use-after-free if an alias entry is removed while being read,
2 duplicate entries when two threads register the same alias,
3 inconsistent alias mappings observed by consumers.
Protect all traversals, insertions and deletions on
regulator_supply_alias_list with the existing regulator_list_mutex.
Fixes: a06ccd9c3785f ("regulator: core: Add ability to create a lookup alias for supply")

commit a89d14410ea0352420f03cddc67e0002dcc8f9a5
category: bugfix
bugzilla: https://atomgit.com/src-openeuler/kernel/issues/13126
CVE: CVE-2023-54283
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id…
--------------------------------
[ Upstream commit ee9fd0ac3017c4313be91a220a9ac4c99dde7ad4 ]
KCSAN reported a data-race when accessing node->ref.
Although node->ref does not have to be accurate,
take this chance to use a more common READ_ONCE() and WRITE_ONCE()
pattern instead of data_race().
There is an existing bpf_lru_node_is_ref() and bpf_lru_node_set_ref().
This patch also adds bpf_lru_node_clear_ref() to do the
WRITE_ONCE(node->ref, 0) also.

CVE: CVE-2025-68354
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?…
--------------------------------
regulator_supply_alias_list was accessed without any locking in
regulator_supply_alias(), regulator_register_supply_alias(), and
regulator_unregister_supply_alias(). Concurrent registration,
unregistration and lookups can race, leading to:
1 use-after-free if an alias entry is removed while being read,
2 duplicate entries when two threads register the same alias,
3 inconsistent alias mappings observed by consumers.
Protect all traversals, insertions and deletions on
regulator_supply_alias_list with the existing regulator_list_mutex.

--------------------------------
[ Upstream commit e120f46768d98151ece8756ebd688b0e43dc8b29 ]
Raw IP packets have no MAC header, leaving skb->mac_header uninitialized.
This can trigger kernel panics on ARM64 when xfrm or other subsystems
access the offset due to strict alignment checks.
Initialize the MAC header to prevent such crashes.
This can trigger kernel panics on ARM when running IPsec over the
qmimux0 interface.

--------------------------------
[ Upstream commit 55fb52ffdd62850d667ebed842815e072d3c9961 ]
mesh_send_done timer is not canceled when hdev is removed, which causes
crash if the timer triggers after hdev is gone.
Cancel the timer when MGMT removes the hdev, like other MGMT timers.
Should fix the BUG: sporadically seen by BlueZ test bot
(in "Mesh - Send cancel - 1" test).

[PATCH] net: usb: qmi_wwan: initialize MAC header offset in qmimux_rx_fixup
by Jiacheng Yu 06 Jan '26
by Jiacheng Yu 06 Jan '26
06 Jan '26
From: Qendrim Maxhuni <qendrim.maxhuni(a)garderos.com>
[ Upstream commit e120f46768d98151ece8756ebd688b0e43dc8b29 ]
Raw IP packets have no MAC header, leaving skb->mac_header uninitialized.
This can trigger kernel panics on ARM64 when xfrm or other subsystems
access the offset due to strict alignment checks.
Initialize the MAC header to prevent such crashes.
This can trigger kernel panics on ARM when running IPsec over the
qmimux0 interface.

--------------------------------
[ Upstream commit b5bbc6551297447d3cca55cf907079e206e9cd82 ]
HW may generate completions that indicates QP is destroyed.
Driver should not be scheduling any more completion handlers
for this QP, after the QP is destroyed. Since CQs are active
during the QP destroy, driver may still schedule completion
handlers. This can cause a race where the destroy_cq and poll_cq
running simultaneously.
Snippet of kernel panic while doing bnxt_re driver load unload in loop.
This indicates a poll after the CQ is freed.

To avoid this, complete all completion handlers before returning the
destroy QP. If free_cq is called soon after destroy_qp, IB stack
will cancel the CQ work before invoking the destroy_cq verb and
this will prevent any race mentioned.

[ Upstream commit e120f46768d98151ece8756ebd688b0e43dc8b29 ]
Raw IP packets have no MAC header, leaving skb->mac_header uninitialized.
This can trigger kernel panics on ARM64 when xfrm or other subsystems
access the offset due to strict alignment checks.
Initialize the MAC header to prevent such crashes.
This can trigger kernel panics on ARM when running IPsec over the
qmimux0 interface.

commit 08469f5393a1a39f26a6e2eb2e8c33187665c1f4
category: bugfix
bugzilla: https://atomgit.com/src-openeuler/kernel/issues/11579
CVE: CVE-2025-68209
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id…
--------------------------------
[ Upstream commit e5eba42f01340f73888dfe560be2806057c25913 ]
Currently, CQs without a completion function are assigned the
mlx5_add_cq_to_tasklet function by default. This is problematic since
only user CQs created through the mlx5_ib driver are intended to use
this function.
Additionally, all CQs that will use doorbells instead of polling for
completions must call mlx5_cq_arm. However, the default CQ creation flow
leaves a valid value in the CQ's arm_db field, allowing FW to send
interrupts to polling-only CQs in certain corner cases.
These two factors would allow a polling-only kernel CQ to be triggered
by an EQ interrupt and call a completion function intended only for user
CQs, causing a null pointer exception.
Some areas in the driver have prevented this issue with one-off fixes
but did not address the root cause.
This patch fixes the described issue by adding defaults to the create CQ
flow. It adds a default dummy completion function to protect against
null pointer exceptions, and it sets an invalid command sequence number
by default in kernel CQs to prevent the FW from sending an interrupt to
the CQ until it is armed. User CQs are responsible for their own
initialization values.
Callers of mlx5_core_create_cq are responsible for changing the
completion function and arming the CQ per their needs.

Backport the following patches for OLK-5.10:
- e14f9d96acb7 mm/memory-failure: support disabling soft offline for HugeTLB pages
- 2f0c01a690d1 mm/memory-failure: userspace controls soft-offlining pages
- 9bb3fd60f91e arm64: mm: Add copy mc support for all migrate_page
- 45dbef4c04f6 mm: page_eject: Add mc support during offline page
- b7f5b9ef641a mm: Update PF_COREDUMP_MCS to PF_MCS
- 17d08829674a mm/hwpoison: add migrate_page_mc_extra()
- c10a520c4102 mm/hwpoison: introduce copy_mc_highpages
- d689cd1c1479 mm/hwpoison: arm64: introduce copy_mc_highpage
Add mcs support for migrate page & support disabling soft offline for
HugeTLB pages.
Since UCE kernel recovery is needed by this. This should be enable
with the following step:
- echo 1 > /proc/sys/kernel/uce_kernel_recovery
Disable soft offline support for hugetlb with the following step:
- echo 3 > /proc/sys/vm/enable_soft_offline
Since ARCH_ENABLE_HUGEPAGE_MIGRATION is not enabled in openeuler_defconfig
in arm64. There is no need to merge soft-offining related patches.
Change log since v1:
- add patch list from OLK-5.10
- add ARCH_ENABLE_HUGEPAGE_MIGRATION related comment
- bugfix for __copy_huge_page

commit c2a88e8bdf5f6239948d75283d0ae7e0c7945b03 upstream.
dmt_mode is allocated and never freed in this function.
It was found with the ast driver, but most drivers using generic fbdev
setup are probably affected.
This fixes the following kmemleak report:

[PATCH OLK-6.6] wifi: rtl818x: rtl8187: Fix potential buffer underflow in rtl8187_rx_cb()

commit b647d2574e4583c2e3b0ab35568f60c88e910840
category: bugfix
bugzilla: https://atomgit.com/src-openeuler/kernel/issues/12718
CVE: CVE-2025-68362
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id…
--------------------------------
The rtl8187_rx_cb() calculates the rx descriptor header address
by subtracting its size from the skb tail pointer.
However, it does not validate if the received packet
(skb->len from urb->actual_length) is large enough to contain this
header.
If a truncated packet is received, this will lead to a buffer
underflow, reading memory before the start of the skb data area,
and causing a kernel panic.
Add length checks for both rtl8187 and rtl8187b descriptor headers
before attempting to access them, dropping the packet cleanly if the
check fails.

In get_guest_rtc_ns(), "s->base_rtc" is uint64_t, which multiplied by
"NANOSECONDS_PER_SECOND" may overflow the uint64_t type.
Fix it by avoiding adding s->base_rtc in get_guest_rtc_ns_offset(),
because get_guest_rtc_ns() is used either take the remainder of
NANOSECONDS_PER_SECOND or take the quotient of NANOSECONDS_PER_SECOND.

commit 84250da1c63cb7d421a3b4812b5c2ce2e47d31a1
category: bugfix
bugzilla: https://atomgit.com/src-openeuler/kernel/issues/11452
CVE: CVE-2023-53826
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id…
--------------------------------
[ Upstream commit a240bc5c43130c6aa50831d7caaa02a1d84e1bce ]
Wear-leveling entry could be freed in error path, which may be accessed
again in eraseblk_count_seq_show(), for example:
__erase_worker eraseblk_count_seq_show
wl = ubi->lookuptbl[*block_number]
if (wl)
wl_entry_destroy
ubi->lookuptbl[e->pnum] = NULL
kmem_cache_free(ubi_wl_entry_slab, e)
erase_count = wl->ec // UAF!
Wear-leveling entry updating/accessing in ubi->lookuptbl should be
protected by ubi->wl_lock, fix it by adding ubi->wl_lock to serialize
wl entry accessing between wl_entry_destroy() and
eraseblk_count_seq_show().
Fetch a reproducer in [Link].

CVE: CVE-2025-40304
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=…
--------------------------------
[ Upstream commit 3637d34b35b287ab830e66048841ace404382b67 ]
Add bounds checking to prevent writes past framebuffer boundaries when
rendering text near screen edges. Return early if the Y position is off-screen
and clip image height to screen boundary. Break from the rendering loop if the
X position is off-screen. When clipping image width to fit the screen, update
the character count to match the clipped width to prevent buffer size
mismatches.
Without the character count update, bit_putcs_aligned and bit_putcs_unaligned
receive mismatched parameters where the buffer is allocated for the clipped
width but cnt reflects the original larger count, causing out-of-bounds writes.

[PATCH OLK-5.10] wifi: rtl818x: rtl8187: Fix potential buffer underflow in rtl8187_rx_cb()

CVE: CVE-2025-68362
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id…
--------------------------------
The rtl8187_rx_cb() calculates the rx descriptor header address
by subtracting its size from the skb tail pointer.
However, it does not validate if the received packet
(skb->len from urb->actual_length) is large enough to contain this
header.
If a truncated packet is received, this will lead to a buffer
underflow, reading memory before the start of the skb data area,
and causing a kernel panic.
Add length checks for both rtl8187 and rtl8187b descriptor headers
before attempting to access them, dropping the packet cleanly if the
check fails.

[ Upstream commit f6ee30407e883042482ad4ad30da5eaba47872ee ]
There are some struct drm_driver fields that are required by drivers since
drm_copy_field() attempts to copy them to user-space via DRM_IOCTL_VERSION.
But it can be possible that a driver has a bug and did not set some of the
fields, which leads to drm_copy_field() attempting to copy a NULL pointer:

commit c2a88e8bdf5f6239948d75283d0ae7e0c7945b03 upstream.
dmt_mode is allocated and never freed in this function.
It was found with the ast driver, but most drivers using generic fbdev
setup are probably affected.
This fixes the following kmemleak report:

------------------
[ Upstream commit bce2b0539933e485d22d6f6f076c0fcd6f185c4c ]
In idmouse_create_image, if any ftip_command fails, it will
go to the reset label. However, this leads to the data in
bulk_in_buffer[HEADER..IMGSIZE] uninitialized. And the check
for valid image incurs an uninitialized dereference.
Fix this by moving the check before reset label since this
check only be valid if the data after bulk_in_buffer[HEADER]
has concrete data.
Note that this is found by KMSAN, so only kernel compilation
is tested.

[PATCH OLK-6.6] usb: uas: fix urb unmapping issue when the uas device is remove during ongoing data transfer

commit e3a55221f4de080cb7a91ba10f01c4f708603f8d
category: bugfix
bugzilla: https://atomgit.com/src-openeuler/kernel/issues/12692
CVE: CVE-2025-68331
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id…
--------------------------------
commit 26d56a9fcb2014b99e654127960aa0a48a391e3c upstream.
When a UAS device is unplugged during data transfer, there is
a probability of a system panic occurring. The root cause is
an access to an invalid memory address during URB callback handling.
Specifically, this happens when the dma_direct_unmap_sg() function
is called within the usb_hcd_unmap_urb_for_dma() interface, but the
sg->dma_address field is 0 and the sg data structure has already been
freed.
The SCSI driver sends transfer commands by invoking uas_queuecommand_lck()
in uas.c, using the uas_submit_urbs() function to submit requests to USB.
Within the uas_submit_urbs() implementation, three URBs (sense_urb,
data_urb, and cmd_urb) are sequentially submitted. Device removal may
occur at any point during uas_submit_urbs execution, which may result
in URB submission failure. However, some URBs might have been successfully
submitted before the failure, and uas_submit_urbs will return the -ENODEV
error code in this case. The current error handling directly calls
scsi_done(). In the SCSI driver, this eventually triggers scsi_complete()
to invoke scsi_end_request() for releasing the sgtable. The successfully
submitted URBs, when being unlinked to giveback, call
usb_hcd_unmap_urb_for_dma() in hcd.c, leading to exceptions during sg
unmapping operations since the sg data structure has already been freed.
This patch modifies the error condition check in the uas_submit_urbs()
function. When a UAS device is removed but one or more URBs have already
been successfully submitted to USB, it avoids immediately invoking
scsi_done() and save the cmnd to devinfo->cmnd array. If the successfully
submitted URBs is completed before devinfo->resetting being set, then
the scsi_done() function will be called within uas_try_complete() after
all pending URB operations are finalized. Otherwise, the scsi_done()
function will be called within uas_zap_pending(), which is executed after
usb_kill_anchored_urbs().
The error handling only takes effect when uas_queuecommand_lck() calls
uas_submit_urbs() and returns the error value -ENODEV . In this case,
the device is disconnected, and the flow proceeds to uas_disconnect(),
where uas_zap_pending() is invoked to call uas_try_complete().
Fixes: eb2a86ae8c54 ("USB: UAS: fix disconnect by unplugging a hub")

As [lru_,]percpu_hash maps support BPF_KPTR_{REF,PERCPU}, missing
calls to 'bpf_obj_free_fields()' in 'pcpu_copy_value()' could cause the
memory referenced by BPF_KPTR_{REF,PERCPU} fields to be held until the
map gets freed.
Fix this by calling 'bpf_obj_free_fields()' after
'copy_map_value[,_long]()' in 'pcpu_copy_value()'.

OPDESC() simply indexes into nfsd4_ops[] by the op's operation
number, without range checking that value. It assumes callers are
careful to avoid calling it with an out-of-bounds opnum value.
nfsd4_decode_compound() is not so careful, and can invoke OPDESC()
with opnum set to OP_ILLEGAL, which is 10044 -- well beyond the end
of nfsd4_ops[].

--------------------------------
[ Upstream commit d35acc1be3480505b5931f17e4ea9b7617fea4d3 ]
Gerrard Tai reported a race condition in PRIO, whenever SFQ perturb timer
fires at the wrong time.
The race is as follows:
CPU 0 CPU 1
[1]: lock root
[2]: qdisc_tree_flush_backlog()
[3]: unlock root
|
| [5]: lock root
| [6]: rehash
| [7]: qdisc_tree_reduce_backlog()
|
[4]: qdisc_put()
This can be abused to underflow a parent's qlen.
Calling qdisc_purge_queue() instead of qdisc_tree_flush_backlog()
should fix the race, because all packets will be purged from the qdisc
before releasing the lock.

Fix the incorrect dirty range tracking in iomap_folio_mkwrite_iter()
which could lead to blocks being missed during writeback. Previously,
iomap_set_range_dirty() was called with a wrong offset (0), which may
cause some modified blocks not being marked as dirty and thus skip
writeback.
Calculate the correct offset within the folio from the iterator position
to ensure all modified blocks are properly marked dirty and written back.
Fixes: 0b4d2d8fba90 ("iomap: correct the dirty length in page mkwrite")

------------------------------------------
In our testing, under memory pressure, it becomes difficult totrigger an
OOM(out-of-memory) kill when regular memory allocation competes
concurrently with driver GFP_ATOMIC allocations.
This occurs because GFP_ATOMIC allocations can succeed from as low as 3/8
of the min watermark. In such a situation, even if direct reclaim can free
a small number of pages, regular memory requests may still fail because the
current watermark remains too high for them.
In the following scenario:
restart:
__alloc_pages_direct_reclaim // reclaims a small number of pages
should_reclaim_retry // watermark too high for user
// resets no_progress_loops to zero and
// goes to restart
goto restart;
In our production environment, we encountered a case where memory
allocation performed __alloc_pages_direct_reclaim 257 times without
either succeeding or triggering OOM, causing service freezes.
To avoid meaningless continuous direct reclaim loops, skip watermark
check for non mirrored zone if memory reliable enabled.

--------------------------------
If the fallback for memory reliable is enabled, direct reclaim will be
used if the task's reliable memory limit is reached and pages need to
be released. However, percpu_counter_read_positive() provides a fast
but imprecise counter reading. During limit enforcement, this inaccuracy
may cause the observed usage to appear significantly larger than the
actual value. As a result, even repeated constrained reclaim attempts
may fail to bring memory usage below the limit, eventually leading to
OOM.
To avoid this issue, use an accurate counter check when determining
whether the reliable memory limit has been exceeded.

On kvm qemu with cmos rtc and mc146818 chip, when the read time jump to
a future time after set the uie timer expire with a current RTC time,
rtc_timer_do_work() will loop for a while util softlockup because
the expiration of the uie timer was way before the current
RTC time and a new timer will be enqueued until the current rtc time
is reached, as below:
Fix it by voluntarily yield the CPU in the loop in rtc_timer_do_work().
RTC_UIE_ON:
read now: 2019:04:08:12:32:27, add timer0 (expire: 2019:04:08:12:32:28)

The cause of the issue is that brelse() is called on both ofibh.sbh
and ofibh.ebh by udf_find_entry() when it returns NULL. However,
brelse() is called by udf_rename(), too. So, b_count on buffer_head
becomes unbalanced.
This patch fixes the issue by not calling brelse() by udf_rename()
when udf_find_entry() returns NULL.

[ Upstream commit c505feba4c0d76084e56ec498ce819f02a7043ae ]
syzkaller reported a KASAN use-after-free:
https://syzkaller.appspot.com/bug?extid=2ae90e873e97f1faf6f2
The referenced fuzzed image actually has two issues:
- m_pa == 0 as a non-inlined pcluster;
- The logical length is longer than its physical length.
The first issue has already been addressed. This patch addresses
the second issue by checking the extent length validity.

CVE: CVE-2025-68372
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?…
------------------
There is one uaf issue in recv_work when running NBD_CLEAR_SOCK and
NBD_CMD_RECONFIGURE:
nbd_genl_connect // conf_ref=2 (connect and recv_work A)
nbd_open // conf_ref=3
recv_work A done // conf_ref=2
NBD_CLEAR_SOCK // conf_ref=1
nbd_genl_reconfigure // conf_ref=2 (trigger recv_work B)
close nbd // conf_ref=1
recv_work B
config_put // conf_ref=0
atomic_dec(&config->recv_threads); -> UAF
Or only running NBD_CLEAR_SOCK:
nbd_genl_connect // conf_ref=2
nbd_open // conf_ref=3
NBD_CLEAR_SOCK // conf_ref=2
close nbd
nbd_release
config_put // conf_ref=1
recv_work
config_put // conf_ref=0
atomic_dec(&config->recv_threads); -> UAF
Commit 87aac3a80af5 ("nbd: call nbd_config_put() before notifying the
waiter") moved nbd_config_put() to run before waking up the waiter in
recv_work, in order to ensure that nbd_start_device_ioctl() would not
be woken up while nbd->task_recv was still uncleared.
However, in nbd_start_device_ioctl(), after being woken up it explicitly
calls flush_workqueue() to make sure all current works are finished.
Therefore, there is no need to move the config put ahead of the wakeup.
Move nbd_config_put() to the end of recv_work, so that the reference is
held for the whole lifetime of the worker thread. This makes sure the
config cannot be freed while recv_work is still running, even if clear
+ reconfigure interleave.
In addition, we don't need to worry about recv_work dropping the last
nbd_put (which causes deadlock):
path A (netlink with NBD_CFLAG_DESTROY_ON_DISCONNECT):
connect // nbd_refs=1 (trigger recv_work)
open nbd // nbd_refs=2
NBD_CLEAR_SOCK
close nbd
nbd_release
nbd_disconnect_and_put
flush_workqueue // recv_work done
nbd_config_put
nbd_put // nbd_refs=1
nbd_put // nbd_refs=0
queue_work
path B (netlink without NBD_CFLAG_DESTROY_ON_DISCONNECT):
connect // nbd_refs=2 (trigger recv_work)
open nbd // nbd_refs=3
NBD_CLEAR_SOCK // conf_refs=2
close nbd
nbd_release
nbd_config_put // conf_refs=1
nbd_put // nbd_refs=2
recv_work done // conf_refs=0, nbd_refs=1
rmmod // nbd_refs=0

In the error path of raid10_run(), 'conf' need be freed, however,
'conf->bio_split' is missed and memory will be leaked.
Since there are 3 places to free 'conf', factor out a helper to fix the
problem.

We attempted to use RCU to protect the pointer 'thread', but directly
passed the value when calling md_wakeup_thread(). This means that the
RCU pointer has been acquired before rcu_read_lock(), which renders
rcu_read_lock() ineffective and could lead to a use-after-free.

[ Upstream commit 6d87cd5335784351280f82c47cc8a657271929c3 ]
Blktests test cases nvme/014, 057 and 058 fail occasionally due to a
lockdep WARN. As reported in the Closes tag URL, the WARN indicates that
a deadlock can happen due to the dependency among disk->open_mutex,
kblockd workqueue completion and partition_scan_work completion.
To avoid the lockdep WARN and the potential deadlock, cut the dependency
by running the partition_scan_work not by kblockd workqueue but by
nvme_wq.

commit d46c69a087aa3d1513f7a78f871b80251ea0c1ae
category: bugfix
bugzilla: https://atomgit.com/src-openeuler/kernel/issues/12897
CVE: CVE-2025-68745
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?…
--------------------------------
Commit aefed3e5548f ("scsi: qla2xxx: target: Fix offline port handling
and host reset handling") caused two problems:
1. Commands sent to FW, after chip reset got stuck and never freed as FW
is not going to respond to them anymore.
2. BUG_ON(cmd->sg_mapped) in qlt_free_cmd(). Commit 26f9ce53817a
("scsi: qla2xxx: Fix missed DMA unmap for aborted commands")
attempted to fix this, but introduced another bug under different
circumstances when two different CPUs were racing to call
qlt_unmap_sg() at the same time: BUG_ON(!valid_dma_direction(dir)) in
dma_unmap_sg_attrs().
So revert "scsi: qla2xxx: Fix missed DMA unmap for aborted commands" and
partially revert "scsi: qla2xxx: target: Fix offline port handling and
host reset handling" at __qla2x00_abort_all_cmds.

commit adb7577e23a431fc53aa1b6107733c0d751015fb
category: bugfix
bugzilla: https://atomgit.com/src-openeuler/kernel/issues/12813
CVE: CVE-2025-68734
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id…
--------------------------------
commit 3f978e3f1570155a1327ffa25f60968bc7b9398f upstream.
In hfcsusb_probe(), the memory allocated for ctrl_urb gets leaked when
setup_instance() fails with an error code. Fix that by freeing the urb
before freeing the hw structure. Also change the error paths to use the
goto ladder style.
Compile tested only. Issue found using a prototype static analysis tool.
