commit 9d2231c5d74e13b2a0546fee6737ee4446017903
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I4WUKP?from=project-issue
CVE: CVE-2022-0847
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/l…
--------------------------------
The functions copy_page_to_iter_pipe() and push_pipe() can both
allocate a new pipe_buffer, but the "flags" member initializer is
missing.

category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I4SA9G
---------------------------
No need to give up the original sd minor even with this option,
and if we did we'd also need to fix the number of minors for
this configuration to actually work.

[PATCH openEuler-5.10] lib/iov_iter: initialize "flags" in new pipe_buffer
by Zheng Zengkai 08 Mar '22
by Zheng Zengkai 08 Mar '22
08 Mar '22
From: Max Kellermann <max.kellermann(a)ionos.com>
mainline inclusion
from mainline-v5.17-rc6
commit 9d2231c5d74e13b2a0546fee6737ee4446017903
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I4WUKP?from=project-issue
CVE: CVE-2022-0847
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/l…
--------------------------------
The functions copy_page_to_iter_pipe() and push_pipe() can both
allocate a new pipe_buffer, but the "flags" member initializer is
missing.

[PATCH openEuler-1.0-LTS] hugetlbfs: fix a truncation issue in hugepages parameter
by Yang Yingliang 08 Mar '22
by Yang Yingliang 08 Mar '22
08 Mar '22
From: Liu Yuntao <liuyuntao10(a)huawei.com>
mainline inclusion
from mainline-v5.17-rc6
commit e79ce9832316e09529b212a21278d68240ccbf1f
category: bugfix
bugzilla: 186043
CVE: NA
-------------------------------------------------
When we specify a large number for node in hugepages parameter, it may
be parsed to another number due to truncation in this statement:
node = tmp;
For example, add following parameter in command line:
hugepagesz=1G hugepages=4294967297:5
and kernel will allocate 5 hugepages for node 1 instead of ignoring it.
I move the validation check earlier to fix this issue, and slightly
simplifies the condition here.

各位好，
根据前期沟通，OSV、驱动兼容性SIG都对内核接口兼容性提出了诉求。根据前期
沟通的信息，以 openEuler-20.03-LTS 驱动列表、兼容性KABI 白名单为基础，
以如下几个方面为白名单移除或新增的输入，形成一份 openEuler-22.03-LTS
兼容性 KABI 白名单初稿，请大家评审。

KABI (Kernel Application Binary Interface) 兼容，即内核与驱动的二进制兼容。
就是驱动不用重新编译，就可以在新内核上安装使用。如果驱动用到的接口都
是兼容的，那么驱动就可以不用重新编译就可以在新版本安装使用。上游社区
考虑到便于开发、和防止架构腐化，不考虑 KABI 的兼容性。业界的 KABI 兼容
都是由 Linux 发行版来做的，而且兼容的接口越多、维护时间越长，维护成本
也越高。
openEuler 通过多次与下游OSV和驱动团队交流，根据下游反馈的诉求，
openEuler-22.03-LTS 版本，提供一定范围的 KABI 兼容能力，目的是
使常用的板卡驱动，在 openEuler-22.03-LTS 版本能兼容。
KABI 兼容列表白名单的主要输入是驱动（ko），我们根据下游的反馈，在
openEuler-20.03-LTS 驱动列表的基础上，新增nvidia.ko、nvidia_vgpu_vfio.ko，
作为兼容的目标，得到驱动列表如下。
ARM64 版本拟兼容的驱动（ko）列表：
amdgpu.ko
bnx2.ko
bnx2x.ko
bnxt_en.ko
bnxt_re.ko
hclge.ko
hclgevf.ko
hifc.ko
hinic.ko
hnae3.ko

nvidia_vgpu_vfio.ko
nouveau.ko
nvme.ko
qed.ko
qede.ko
qla2xxx.ko
smartpqi.ko
tg3.ko
txgbe.ko
X86 版本拟兼容的驱动（ko）列表：
amdgpu.ko
bnx2.ko
bnx2x.ko
bnxt_en.ko

hifc.ko

nouveau.ko
nvme.ko
qed.ko
qede.ko

smartpqi.ko
tg3.ko
txgbe.ko
重要的说明和提示：
1. 上述列表中多数驱动，还没有针对 openEuler-22.03-LTS 的正式二进制版本，因此我们
根据开源的版本或相近的版本收集了相关 KABI 列表，可能与板卡厂商的最终发布
的版本存在少量差异。下游OSV或驱动团队如果发现有接口没在给出的列表中的，
可以在评审过程中提出来。
2. 如果有新增 KABI 兼容性的诉求，需要给出需要兼容的 KABI 接口名称，以及使用
到的驱动名称，以方便评估。
3. 评审反馈，可以在 issue 中反馈，https://gitee.com/openeuler/kernel/issues/I4U6NZ
也可以通过回复邮件反馈。
4. 收集评审反馈信息的时间为1周，截止到下周五（3月11日）下午17:00.

[PATCH openEuler-1.0-LTS] mm: fix missing reclaim of low-reliable page cache
by Yang Yingliang 04 Mar '22
by Yang Yingliang 04 Mar '22
04 Mar '22
From: Chen Wandun <chenwandun(a)huawei.com>
hulk inclusion
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I4SK3S
CVE: NA
--------------------------------
Low-reliable memory is located in ZONE_MOVABLE, so gfp
should contain GFP_HIGHMEM and GFP_MOVABLE when reclaim
memory.
