openEuler-22.03-LTS 兼容性 KABI 白名单初稿预审

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。 ARM64 版本变更统计结果：

+--------------------------------+-----------+------------------------------------------------------------------------+ 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 hns3.ko i40e.ko ice.ko igb.ko ixgbe.ko ixgbevf.ko lpfc.ko megaraid_sas.ko mlx4_core.ko mlx4_ib.ko mlx5_core.ko mlx5_ib.ko mpt3sas.ko nvidia.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 bnxt_re.ko hifc.ko hinic.ko i40e.ko ice.ko igb.ko ixgbe.ko ixgbevf.ko lpfc.ko megaraid_sas.ko mlx4_core.ko mlx4_ib.ko

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. --- openEuler kernel SIG， 2022-3-4 --- 附1：ARM64 平台 KABI 白名单列表初稿（2814个） acpi_bus_get_device

[PATCH openEuler-5.10 1/4] rseq, ptrace: Add PTRACE_GET_RSEQ_CONFIGURATION request
by Zheng Zengkai 03 Mar '22

03 Mar '22

From: Piotr Figiel <figiel(a)google.com> mainline inclusion from mainline-5.13-rc1 commit 90f093fa8ea48e5d991332cee160b761423d55c1 category: feature feature: Userspace percpu bugzilla: https://gitee.com/openeuler/kernel/issues/I4W2BQ CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- For userspace checkpoint and restore (C/R) a way of getting process state containing RSEQ configuration is needed. There are two ways this information is going to be used: - to re-enable RSEQ for threads which had it enabled before C/R - to detect if a thread was in a critical section during C/R Since C/R preserves TLS memory and addresses RSEQ ABI will be restored using the address registered before C/R. Detection whether the thread is in a critical section during C/R is needed to enforce behavior of RSEQ abort during C/R. Attaching with ptrace() before registers are dumped itself doesn't cause RSEQ abort. Restoring the instruction pointer within the critical section is problematic because rseq_cs may get cleared before the control is passed to the migrated application code leading to RSEQ invariants not being preserved. C/R code will use RSEQ ABI address to find the abort handler to which the instruction pointer needs to be set. To achieve above goals expose the RSEQ ABI address and the signature value with the new ptrace request PTRACE_GET_RSEQ_CONFIGURATION. This new ptrace request can also be used by debuggers so they are aware of stops within restartable sequences in progress.

[PATCH openEuler-5.10 1/9] kfence: Add a module parameter to adjust kfence objects
by Zheng Zengkai 02 Mar '22

02 Mar '22

From: Peng Liu <liupeng256(a)huawei.com> hulk inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I4V388 CVE: NA -------------------------------- KFENCE is designed to be enabled in production kernels, but it can be also useful in some debug situations. For machines with limited memory and CPU resources, KASAN is really hard to run. Fortunately, KFENCE can be a suitable candidate. For KFENCE running on a single machine, the possibility of discovering existed bugs will increase as the increasing of KFENCE objects, but this will cost more memory. In order to balance the possibility of discovering existed bugs and memory cost, KFENCE objects need to be adjusted according to memory resources for a compiled kernel Image. Add a module parameter to adjust KFENCE objects will make kfence to use in different machines with the same kernel Image. In short, the following reasons motivate us to add this parameter. 1) In some debug situations, this will make kfence flexible. 2) For some production machines with different memory and CPU size, this will reduce the kernel-Image-version burden. The main change is just using kfence_num_objects to replace config CONFIG_KFENCE_NUM_OBJECTS for dynamic configuration convenient. To make compatible, kfence_metadata and alloc_covered are alloced by memblock_alloc. Considering "cat /sys/kernel/debug/kfence/objects" will read kfence_metadata, the initialization of this fs should check whether kfence_metadata is successfully allocated. Unfortunately, dynamic allocation require the KFENCE pool size to be a configurable variable, which lead to additional instructions (eg, load) added to the fast path of the memory allocation. As a result, the performance will degrade. To avoid bad performance in production machine, an ugly macro is used to isolate the changes.
