From: Dinghao Liu <dinghao.liu(a)zju.edu.cn> stable inclusion from stable-v5.10.204 commit 49809af89c07c51eecba64abb013c78ff6812156 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 d007caaaf052f82ca2340d4c7b32d04a3f5dbf3f ] When flow_indr_dev_register() fails, bnxt_init_tc will free bp->tc_info through kfree(). However, the caller function bnxt_init_one() will ignore this failure and call bnxt_shutdown_tc() on failure of bnxt_dl_register(), where a use-after-free happens. Fix this issue by setting bp->tc_info to NULL after kfree().

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(). However, this could overlap with the EEH driver's attempt to reset the device using bnx2x_io_slot_reset(), which also tries to free SGEs. This race condition can result in system crashes due to accessing freed memory locations in bnx2x_free_rx_sge() 799 static inline void bnx2x_free_rx_sge(struct bnx2x *bp, 800 struct bnx2x_fastpath *fp, u16 index) 801 { 802 struct sw_rx_page *sw_buf = &fp->rx_page_ring[index]; 803 struct page *page = sw_buf->page; .... where sw_buf was set to NULL after the call to dma_unmap_page() by the preceding thread.

[PATCH openEuler-22.03-LTS] nvme-fc: do not wait in vain when unloading module

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.

[PATCH OLK-5.10] net/tg3: fix race condition in tg3_reset_task()

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.) 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.

[PATCH OLK-6.6] mm: prepare to support weighted interleaving mempolicy
by Ze Zuo 15 May '24

15 May '24

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.

[PATCH] iommu/iova: Make depot list more efficient
by Zhang Zekun 15 May '24

15 May '24

In some scenarios in which is sensitive to the efficiency of allocating iova from iova_rcache. The commit 911aa1245da8 ("iommu/iova: Make the rcache depot scale better") change the format of depot from the fix length array to a list to make depot scale better for machines which has much cores. But the list operation is not as efficiency as the array operation, for some test case, such as IP tansfering, in which allocating iova from iova_rcache can become a bottle neck, this list operation can be reflected by a performance decrease. We can see the higher occupation of queue_iova() and __iova_rcache_get() in perf top. Operating iova_rache->depot on a list: 14.47% [kernel] [k] queue_iova 12.99% [kernel] [k] __iova_rcache_get 8.22% [kernel] [k] __arm_lpae_unmap 6.98% [kernel] [k] arm_lpae_map 6.20% [kernel] [k] native_queued_spin_unlock 4.63% [kernel] [k] __arm_lpae_map 2.56% [kernel] [k] __dev_queue_xmit Operating iova_rache->depot on a array: 10.50% [kernel] [k] __arm_lpae_unmap 7.80% [kernel] [k] native_queued_spin_unlock 7.23% [kernel] [k] queue_iova 7.16% [kernel] [k] arm_lpae_map 5.90% [kernel] [k] __arm_lpae_map 3.67% [kernel] [k] __iova_rcache_get 3.20% [kernel] [k] __dev_queue_xmit To make the depot operation more efficient, we can introduce a array buffer before using the depot list, the length of the array will be set to NR_CPUS, which should be enough for most workloads. iova_rcache will first try to use magazines in the array part of the depot. If we have too much magazines which need to be put in the depot, then the depot list will be used.

[PATCH OLK-5.10] sh: push-switch: Reorder cleanup operations to avoid use-after-free bug
by Guo Mengqi 15 May '24

15 May '24

From: Guan Jing <guanjing6(a)huawei.com> mainline inclusion from mainline-v6.5-rc2 commit 246f80a0b17f8f582b2c0996db02998239057c65 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9CTGE CVE: CVE-2023-52629 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- The original code puts flush_work() before timer_shutdown_sync() in switch_drv_remove(). Although we use flush_work() to stop the worker, it could be rescheduled in switch_timer(). As a result, a use-after-free bug can occur. The details are shown below: (cpu 0) | (cpu 1) switch_drv_remove() | flush_work() | ... | switch_timer // timer | schedule_work(&psw->work) timer_shutdown_sync() | ... | switch_work_handler // worker kfree(psw) // free | | psw->state = 0 // use This patch puts timer_shutdown_sync() before flush_work() to mitigate the bugs. As a result, the worker and timer will be stopped safely before the deallocate operations. Fixes: 9f5e8eee5cfe ("sh: generic push-switch framework.")

From: Mukesh Ojha <quic_mojha(a)quicinc.com> stable inclusion from stable-v5.10.210 commit 3399cc7013e761fee9d6eec795e9b31ab0cbe475 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9DNGK Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit aed5ed595960c6d301dcd4ed31aeaa7a8054c0c6 ] There is a chance if a frequent switch of the governor done in a loop result in timer list corruption where timer cancel being done from two place one from cancel_delayed_work_sync() and followed by expire_timers() can be seen from the traces[1]. while true do echo "simple_ondemand" > /sys/class/devfreq/1d84000.ufshc/governor echo "performance" > /sys/class/devfreq/1d84000.ufshc/governor done It looks to be issue with devfreq driver where device_monitor_[start/stop] need to synchronized so that delayed work should get corrupted while it is either being queued or running or being cancelled. Let's use polling flag and devfreq lock to synchronize the queueing the timer instance twice and work data being corrupted.
