We only need to send the CMD_SYNC in the granual of the level 3 pagetable block size, this can greatly reduce the amounts of CMD_SYNC times sent to avoiding the errata. Detecting the hardware ability by read the SMMU_USER_CONFIG1. Also, We don't have to send a tlbi before a CMD_SYNC, It will be OK for the hardware to merge the CMD_SYNC.

[PATCH OLK-5.10] cpu/SMT: Make SMT control more robust against enumeration failures
by Yang Yingliang 16 May '24

16 May '24

From: Thomas Gleixner <tglx(a)linutronix.de> mainline inclusion from mainline-v6.7-rc1 commit d91bdd96b55cc3ce98d883a60f133713821b80a6 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I9NZ3E Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- The SMT control mechanism got added as speculation attack vector mitigation. The implemented logic relies on the primary thread mask to be set up properly. This turns out to be an issue with XEN/PV guests because their CPU hotplug mechanics do not enumerate APICs and therefore the mask is never correctly populated. This went unnoticed so far because by chance XEN/PV ends up with smp_num_siblings == 2. So smt_hotplug_control stays at its default value CPU_SMT_ENABLED and the primary thread mask is never evaluated in the context of CPU hotplug. This stopped "working" with the upcoming overhaul of the topology evaluation which legitimately provides a fake topology for XEN/PV. That sets smp_num_siblings to 1, which causes the core CPU hot-plug core to refuse to bring up the APs. This happens because smt_hotplug_control is set to CPU_SMT_NOT_SUPPORTED which causes cpu_smt_allowed() to evaluate the unpopulated primary thread mask with the conclusion that all non-boot CPUs are not valid to be plugged. Make cpu_smt_allowed() more robust and take CPU_SMT_NOT_SUPPORTED and CPU_SMT_NOT_IMPLEMENTED into account. Rename it to cpu_bootable() while at it as that makes it more clear what the function is about. The primary mask issue on x86 XEN/PV needs to be addressed separately as there are users outside of the CPU hotplug code too.

The bnx2x_tx_timeout() schedules reset tasks via bnx2x_sp_rtnl_task(), which ultimately leads to bnx2x_nic_unload(). In bnx2x_nic_unload() SGEs are freed using bnx2x_free_rx_sge_range().

[PATCH openEuler-22.03-LTS 4/4] net/tg3: fix race condition in tg3_reset_task()
by Baogen Shang 15 May '24

15 May '24

From: Thinh Tran <thinhtr(a)linux.vnet.ibm.com> stable inclusion from stable-v5.10.209 commit 1059aa41c5a84abfab4cc7371d6b5ff2b30b6c2d category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I9J6AL CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=… ------------------------- [ Upstream commit 16b55b1f2269962fb6b5154b8bf43f37c9a96637 ] When an EEH error is encountered by a PCI adapter, the EEH driver modifies the PCI channel's state as shown below: enum { /* I/O channel is in normal state */ pci_channel_io_normal = (__force pci_channel_state_t) 1, /* I/O to channel is blocked */ pci_channel_io_frozen = (__force pci_channel_state_t) 2, /* PCI card is dead */ pci_channel_io_perm_failure = (__force pci_channel_state_t) 3, }; If the same EEH error then causes the tg3 driver's transmit timeout logic to execute, the tg3_tx_timeout() function schedules a reset task via tg3_reset_task_schedule(), which may cause a race condition between the tg3 and EEH driver as both attempt to recover the HW via a reset action. EEH driver gets error event --> eeh_set_channel_state() and set device to one of error state above scheduler: tg3_reset_task() get returned error from tg3_init_hw() --> dev_close() shuts down the interface tg3_io_slot_reset() and tg3_io_resume() fail to reset/resume the device To resolve this issue, we avoid the race condition by checking the PCI channel state in the tg3_reset_task() function and skip the tg3 driver initiated reset when the PCI channel is not in the normal state. (The driver has no access to tg3 device registers at this point and cannot even complete the reset task successfully without external assistance.)

To prevent double free a synchronization between nvme_delete_ctrl and ida_destroy has been added by the initial commit. There is some logic around trying to prevent from hanging forever in wait_for_completion, though it does not handling all cases. E.g. blktests is able to reproduce the situation where the module unload hangs forever. If we completely rely on the cleanup code executed from the nvme_delete_ctrl path, all IDs will be freed eventually. This makes calling ida_destroy unnecessary. We only have to ensure that all nvme_delete_ctrl code has been executed before we leave nvme_fc_exit_module. This is done by flushing the nvme_delete_wq workqueue. While at it, remove the unused nvme_fc_wq workqueue too.

hulk inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I9PD4G ---------------------------------------------------------------------- To support weighted interleaving mempolicy, we need to round up two series of patch sets, patch set one is "mempolicy: cleanups leading to NUMA mpol without vma" and patch set two is "mm/mempolicy: weighted interleave mempolicy and sysfs extension", however, where commit ddc1a5cbc05d ("mempolicy: alloc_pages_mpol() for NUMA policy without vma") for patch set one and commit fa3bea4e1f82 ("mm/mempolicy: introduce MPOL_ WEIGHTED_INTERLEAVE for weighted interleaving") will see kabi changes for whitelisted structures, for which the KABI field needs to be reserved in advance for the mempolicy's relevant data structures. v1->v2: -- fix commit bug.

EEH driver gets error event --> eeh_set_channel_state() and set device to one of error state above scheduler: tg3_reset_task() get returned error from tg3_init_hw() --> dev_close() shuts down the interface tg3_io_slot_reset() and tg3_io_resume() fail to reset/resume the device To resolve this issue, we avoid the race condition by checking the PCI channel state in the tg3_reset_task() function and skip the tg3 driver initiated reset when the PCI channel is not in the normal state. (The driver has no access to tg3 device registers at this point and cannot even complete the reset task successfully without external assistance.) We'll leave the reset procedure to be managed by the EEH driver which calls the tg3_io_error_detected(), tg3_io_slot_reset() and tg3_io_resume() functions as appropriate. Adding the same checking in tg3_dump_state() to avoid dumping all device registers when the PCI channel is not in the normal state.

[PATCH OLK-5.10] smart_grid: introducing rebuild_affinity_domain
by Yipeng Zou 15 May '24

15 May '24

hulk inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I9OJK9 CVE: NA ---------------------------------------- Here are many scenarios we tested with smart_grid, we found that the first domain level is key to the benchmark. The reason is that there are many things such as interrupt affinity, memory affinity factor that can have a big impact on the test. Before this patch, the first domain level is unchangeable after creation. This patch introduce the 'cpu.rebuild_affinity_domain' to dynamically reconfigure all domain levels. Typical use cases: echo $cpu_id > cpu.rebuild_affinity_domain The cpu_id means which cpu we want to set first level. If we set cpu_id = 34, we can see some change like: ---------------- ----------------- | level 0 (0-31) | | level 0 (32-63) | ---------------- ----------------- v v ------------------- ------------------ | level 1 (0-63) | | level 1 (0-63) | ------------------- ------------------ v --> v --------------------- -------------------- | level 2 (0-95) | | level 2 (0-95) | --------------------- -------------------- v v ------------------------ ---------------------- | level 3 (0-127) | | level 3 (0-127) | ------------------------ ---------------------- There are number of constraints on the rebuild feature: 1. Only rebuild domain while auto mode disabled. (cpu.dynamic_affinity_mode == 1) 2. Only rebuild on active and housekeeping cpu. (Offline and isolate CPUs are forbidden) 3. This file is write only.

hulk inclusion category: feature https://gitee.com/openeuler/kernel/issues/I9PD4G ---------------------------------------------------------------------- To support weighted interleaving mempolicy, we need to round up two series of patch sets, patch set one is "mempolicy: cleanups leading to NUMA mpol without vma" and patch set two is "mm/mempolicy: weighted interleave mempolicy and sysfs extension", however, where commit ddc1a5cbc05d ("mempolicy: alloc_pages_mpol() for NUMA policy without vma") for patch set one and commit fa3bea4e1f82 ("mm/mempolicy: introduce MPOL_ WEIGHTED_INTERLEAVE for weighted interleaving") will see kabi changes for whitelisted structures, for which the KABI field needs to be reserved in advance for the mempolicy's relevant data structures.
