[PATCH OLK-6.6] fix: fix version showed in ethtool

Fix the version in the output of ethtool commands from empty to the kernel version. Use the macro HINIC3_NIC_DRV_VERSION to record driver changes for developers. The last number 1.0.X grow as minor changes, like this revision which does not affect the main functions. The middle number 1.X.1 iterates with changes to drivers functionality and fixing of serious bugs, and the first one X.0.1 means the number of releases of the driver. --- drivers/net/ethernet/huawei/hinic3/hinic3_ethtool.c | 1 - drivers/net/ethernet/huawei/hinic3/hinic3_nic_dev.h | 2 +- 2 files changed, 1 insertion(+), 2 deletions(-) diff --git a/drivers/net/ethernet/huawei/hinic3/hinic3_ethtool.c b/drivers/net/ethernet/huawei/hinic3/hinic3_ethtool.c index 5a1995956a555..4ea526329d155 100644 --- a/drivers/net/ethernet/huawei/hinic3/hinic3_ethtool.c +++ b/drivers/net/ethernet/huawei/hinic3/hinic3_ethtool.c @@ -45,7 +45,6 @@ static void hinic3_get_drvinfo(struct net_device *netdev, int err; strscpy(info->driver, HINIC3_NIC_DRV_NAME, sizeof(info->driver)); - strscpy(info->version, HINIC3_NIC_DRV_VERSION, sizeof(info->version)); strscpy(info->bus_info, pci_name(pdev), sizeof(info->bus_info)); err = hinic3_get_mgmt_version(nic_dev->hwdev, mgmt_ver, diff --git a/drivers/net/ethernet/huawei/hinic3/hinic3_nic_dev.h b/drivers/net/ethernet/huawei/hinic3/hinic3_nic_dev.h index 2967311aab76c..5868187eafa99 100644 --- a/drivers/net/ethernet/huawei/hinic3/hinic3_nic_dev.h +++ b/drivers/net/ethernet/huawei/hinic3/hinic3_nic_dev.h @@ -17,7 +17,7 @@ #include "hinic3_dcb.h" #define HINIC3_NIC_DRV_NAME "hinic3" -#define HINIC3_NIC_DRV_VERSION "" +#define HINIC3_NIC_DRV_VERSION "1.0.1" #define HINIC3_FUNC_IS_VF(hwdev) (hinic3_func_type(hwdev) == TYPE_VF) -- 2.28.0.windows.1

[PATCH OLK-6.6] powerpc/qspinlock: Fix deadlock in MCS queue
by Yongqiang Liu 25 Sep '24

25 Sep '24

From: "Nysal Jan K.A" <nysal(a)linux.ibm.com> stable inclusion from stable-v6.6.51 commit d84ab6661e8d09092de9b034b016515ef9b66085 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IARYD6 CVE: CVE-2024-46797 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 734ad0af3609464f8f93e00b6c0de1e112f44559 upstream. If an interrupt occurs in queued_spin_lock_slowpath() after we increment qnodesp->count and before node->lock is initialized, another CPU might see stale lock values in get_tail_qnode(). If the stale lock value happens to match the lock on that CPU, then we write to the "next" pointer of the wrong qnode. This causes a deadlock as the former CPU, once it becomes the head of the MCS queue, will spin indefinitely until it's "next" pointer is set by its successor in the queue. Running stress-ng on a 16 core (16EC/16VP) shared LPAR, results in occasional lockups similar to the following: $ stress-ng --all 128 --vm-bytes 80% --aggressive \ --maximize --oomable --verify --syslog \ --metrics --times --timeout 5m watchdog: CPU 15 Hard LOCKUP ......
