[PATCH OLK-6.6 00/10] IPIV-BUGFIX for HIP12
by Jinqian Yang 13 May '25

13 May '25

Compared with the previous IPIV, the IPIV-BUGFIX has the following changes: 1. Use Kconfig to Control whether to enable IPIV. 2. Users use ioctl to control whether to enable IPIV. 3. Use the SMCCC interface for Guest OS to control whether to enable IPIV. 4. make sure vcpu_id == vcpu_idx. 5. the MPIDR cannot be changed When IPIV is enabled. 6. fix bug that ipiv enable is displayed on the host when "kvm-arm.vgic_v4_enable=0 kvm-arm.ipiv_enabled=1" is configured. 7. Add Exception Printing Patch#1 arm64/config: add config to control whether enable IPIV feature Patch#2 KVM: arm64: Introduce ipiv enable ioctl Patch#3 KVM: arm64: Document PV-sgi interface Patch#4 KVM: arm64: Implement PV_SGI related calls Patch#5 irqchip/gic: Add HiSilicon PV SGI support Patch#6 kvm: hisi: make sure vcpu_id and vcpu_idx have same value in IPIv Patch#7 kvm: hisi: Don't allow to change mpidr in IPIv Patch#8 KVM: arm64: using kvm_vgic_global_state for ipiv Patch#9 kvm: hisi: print error for IPIV Patch#10 arm64/kabi: use KABI_EXTEND to skip KABI check Jinqian Yang (4): arm64/config: add config to control whether enable IPIV feature KVM: arm64: using kvm_vgic_global_state for ipiv kvm: hisi: print error for IPIV arm64/kabi: use KABI_EXTEND to skip KABI check Zhou Wang (6): KVM: arm64: Introduce ipiv enable ioctl KVM: arm64: Document PV-sgi interface KVM: arm64: Implement PV_SGI related calls irqchip/gic: Add HiSilicon PV SGI support kvm: hisi: make sure vcpu_id and vcpu_idx have same value in IPIv kvm: hisi: Don't allow to change mpidr in IPIv Documentation/virt/kvm/arm/pvsgi.rst | 33 ++++++++++++++++ arch/arm64/Kconfig | 13 ++++++ arch/arm64/configs/openeuler_defconfig | 1 + arch/arm64/include/asm/kvm_host.h | 3 ++ arch/arm64/kvm/arm.c | 34 ++++++++++++---- arch/arm64/kvm/hisilicon/hisi_virt.c | 25 +++++++++++- arch/arm64/kvm/hisilicon/hisi_virt.h | 20 ++++++++-- arch/arm64/kvm/hypercalls.c | 24 +++++++++++ arch/arm64/kvm/sys_regs.c | 34 +++++++++++----- arch/arm64/kvm/vgic/vgic-init.c | 42 +++++++++++++++++--- arch/arm64/kvm/vgic/vgic-mmio-v3.c | 2 + drivers/irqchip/irq-gic-v3-its.c | 50 ++++++++++++++++------- drivers/irqchip/irq-gic-v3.c | 55 ++++++++++++++++++++------ include/linux/arm-smccc.h | 15 +++++++ include/linux/irqchip/arm-gic-v3.h | 10 +++++ include/linux/irqchip/arm-gic-v4.h | 4 ++ 16 files changed, 311 insertions(+), 54 deletions(-) create mode 100644 Documentation/virt/kvm/arm/pvsgi.rst -- 2.33.0

From: Hongye Lin <linhongye(a)h-partners.com> driver inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/IC76OZ ---------------------------------------------------------------------- Armv8.7 introduces single-copy atomic 64-byte loads and stores instructions and its variants named under FEAT_{LS64, LS64_V}. These features are identified by ID_AA64ISAR1_EL1.LS64 and the use of such instructions in userspace (EL0) can be trapped. In order to support the use of corresponding instructions in userspace: Make ID_AA64ISAR1_EL1.LS64 visbile to userspace Add identifying and enabling in the cpufeature list Expose these support of these features to userspace through HWCAP3 and cpuinfo Mark Brown (2): arm64: Support AT_HWCAP3 binfmt_elf: Wire up AT_HWCAP3 at AT_HWCAP4 Peter Bergner (1): uapi/auxvec: Define AT_HWCAP3 and AT_HWCAP4 aux vector, entries Yicong Yang (4): arm64: Provide basic EL2 setup for FEAT_{LS64, LS64_V} usage at EL0/1 arm64: Add support for FEAT_{LS64, LS64_V} Workaround the issue when compile with CONFIG_FUNCTION_ALIGNMENT_64B KVM: arm64: Enable FEAT_{LS64, LS64_V} in the supported guest Documentation/arch/arm64/booting.rst | 12 +++++ Documentation/arch/arm64/elf_hwcaps.rst | 12 +++-- arch/arm64/Kconfig | 4 ++ arch/arm64/include/asm/cpufeature.h | 3 +- arch/arm64/include/asm/el2_setup.h | 13 ++++++ arch/arm64/include/asm/hwcap.h | 7 ++- arch/arm64/include/uapi/asm/hwcap.h | 6 +++ arch/arm64/kernel/cpufeature.c | 61 +++++++++++++++++++++++++ arch/arm64/kernel/cpuinfo.c | 2 + arch/arm64/kvm/hyp/include/hyp/switch.h | 6 +++ arch/arm64/tools/cpucaps | 4 +- fs/binfmt_elf.c | 6 +++ fs/binfmt_elf_fdpic.c | 6 +++ fs/compat_binfmt_elf.c | 10 ++++ include/uapi/linux/auxvec.h | 2 + 15 files changed, 147 insertions(+), 7 deletions(-) -- 2.33.0

driver inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/IC7CQP ---------------------------------------------------------------------- watchdog perf needs architecture to provide method for converting the watchdog thresh to counter period. For arm64 we're using the max CPU frequency for doing the conversion which is from cpufreq driver. But some cpufreq driver are registered lately, for example cppc_cpufreq will be registered at late initcall which is after the initialization of watchdog perf (initialized in armv8_pmuv3 of device initcall). In such case the period of watchdog will not be accurate enough. Fix this by registering a cpufreq notifier and update the watchdog period once the cpufreq driver is initialized.

In such case the period of watchdog will not be accurate enough. Fix this by registering a cpufreq notifier and update the watchdog period once the cpufreq driver is initialized.

[PATCH openEuler-1.0-LTS] dm ioctl: fix misbehavior if list_versions races with module loading
by Zheng Qixing 13 May '25

13 May '25

From: Mikulas Patocka <mpatocka(a)redhat.com> stable inclusion from stable-v4.19.267 commit 3a1c35d72dc0b34d1e746ed705790c0f630aa427 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IC5BWC CVE: CVE-2022-49771 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… ------------------ commit 4fe1ec995483737f3d2a14c3fe1d8fe634972979 upstream. __list_versions will first estimate the required space using the "dm_target_iterate(list_version_get_needed, &needed)" call and then will fill the space using the "dm_target_iterate(list_version_get_info, &iter_info)" call. Each of these calls locks the targets using the "down_read(&_lock)" and "up_read(&_lock)" calls, however between the first and second "dm_target_iterate" there is no lock held and the target modules can be loaded at this point, so the second "dm_target_iterate" call may need more space than what was the first "dm_target_iterate" returned. The code tries to handle this overflow (see the beginning of list_version_get_info), however this handling is incorrect. The code sets "param->data_size = param->data_start + needed" and "iter_info.end = (char *)vers+len" - "needed" is the size returned by the first dm_target_iterate call; "len" is the size of the buffer allocated by userspace. "len" may be greater than "needed"; in this case, the code will write up to "len" bytes into the buffer, however param->data_size is set to "needed", so it may write data past the param->data_size value. The ioctl interface copies only up to param->data_size into userspace, thus part of the result will be truncated. Fix this bug by setting "iter_info.end = (char *)vers + needed;" - this guarantees that the second "dm_target_iterate" call will write only up to the "needed" buffer and it will exit with "DM_BUFFER_FULL_FLAG" if it overflows the "needed" space - in this case, userspace will allocate a larger buffer and retry. Note that there is also a bug in list_version_get_needed - we need to add "strlen(tt->name) + 1" to the needed size, not "strlen(tt->name)".

[PATCH OLK-6.6] pds_core: handle unsupported PDS_CORE_CMD_FW_CONTROL result
by Yifan Qiao 13 May '25

13 May '25

From: Brett Creeley <brett.creeley(a)amd.com> stable inclusion from stable-v6.6.89 commit cdd784c96fe2e5edbf0ed9b3e96fe776e8092385 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IC6LWK CVE: CVE-2025-37887 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 2567daad69cd1107fc0ec29b1615f110d7cf7385 ] If the FW doesn't support the PDS_CORE_CMD_FW_CONTROL command the driver might at the least print garbage and at the worst crash when the user runs the "devlink dev info" devlink command. This happens because the stack variable fw_list is not 0 initialized which results in fw_list.num_fw_slots being a garbage value from the stack. Then the driver tries to access fw_list.fw_names[i] with i >= ARRAY_SIZE and runs off the end of the array. Fix this by initializing the fw_list and by not failing completely if the devcmd fails because other useful information is printed via devlink dev info even if the devcmd fails.

[PATCH OLK-6.6] usb: chipidea: ci_hdrc_imx: fix usbmisc handling
by Tengda Wu 12 May '25

12 May '25

From: Fedor Pchelkin <pchelkin(a)ispras.ru> stable inclusion from stable-6.6.90 commit 121e9f80ea5478bca3a8f3f26593fd66f87da649 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IC6BLK CVE: CVE-2025-37811 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 4e28f79e3dffa52d327b46d1a78dac16efb5810b upstream. usbmisc is an optional device property so it is totally valid for the corresponding data->usbmisc_data to have a NULL value. Check that before dereferencing the pointer. Found by Linux Verification Center (linuxtesting.org) with Svace static analysis tool.
