[PATCH OLK-6.6 0/2] infiniband/hw/hiroce3: Add Huawei Intelligent Network Card RDMA Driver
by Shuai Wu 26 Apr '24

26 Apr '24

driver inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I9EMOF CVE: NA --------------------------------- The RDMA driver supports the following features: Supports Huawei SP600 series NICs; Supports RoCEv2; Supports RoCE XRC, UD, UC, and RC modes; Supports RoCE UC, RC, and UD local switching; Supports RoCE MR, PD, CQ, QoS, QP, and SRQ management; Supports RoCE congestion control; Supports RoCE Bond; Supports RoCE FLR; Supports RoCE entry specifications; Supports RoCE error detection and reporting; Signed-off-by: Shuai Wu <wushuai51(a)huawei.com> Shuai Wu

[PATCH openEuler-1.0-LTS v3] x86/hyperv: Fix NULL deref in set_hv_tscchange_cb() if Hyper-V setup fails
by Yu Liao 26 Apr '24

26 Apr '24

From: Sean Christopherson <seanjc(a)google.com> stable inclusion from stable-v4.19.218 commit b20ec58f8a6f4fef32cc71480ddf824584e24743 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9FNFO CVE: CVE-2021-47217 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit daf972118c517b91f74ff1731417feb4270625a4 upstream. Check for a valid hv_vp_index array prior to derefencing hv_vp_index when setting Hyper-V's TSC change callback. If Hyper-V setup failed in hyperv_init(), the kernel will still report that it's running under Hyper-V, but will have silently disabled nearly all functionality.

[PATCH OLK-6.6 0/2] update oedefconfig for the minimum set
by Peng Zhang 26 Apr '24

26 Apr '24

From: ZhangPeng <zhangpeng362(a)huawei.com> Update oedefconfig for the minimum set. Changes as follows: For arm64: CONFIG_PVPANIC from not set to y CONFIG_NET_SCH_FQ_CODEL from m to y CONFIG_VIRTIO_MEM from y to m CONFIG_ARM_SPE_PMU from y to m CONFIG_ARM_SMMU_V3_PMU from y to m CONFIG_DRM from y to m CONFIG_RTC_SYSTOHC from not set to y CONFIG_NTB from not set to m For x86: CONFIG_VIRTIO_MMIO from not set to m CONFIG_PCIE_EDR from not set to y CONFIG_IO_STRICT_DEVMEM from not set to y The previous commit updated config without make update_oedefconfig, so now make update_oedefconfig will move some lines.
