[PATCH OLK-5.10] nilfs2: fix hang in nilfs_lookup_dirty_data_buffers()
by Yifan Qiao 08 Apr '24

08 Apr '24

From: Ryusuke Konishi <konishi.ryusuke(a)gmail.com> stable inclusion from stable-v5.10.210 commit 98a4026b22ff440c7f47056481bcbbe442f607d6 category: bugfix bugzilla: 189665 CVE: CVE-2024-26696 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 38296afe3c6ee07319e01bb249aa4bb47c07b534 upstream. Syzbot reported a hang issue in migrate_pages_batch() called by mbind() and nilfs_lookup_dirty_data_buffers() called in the log writer of nilfs2. While migrate_pages_batch() locks a folio and waits for the writeback to complete, the log writer thread that should bring the writeback to completion picks up the folio being written back in nilfs_lookup_dirty_data_buffers() that it calls for subsequent log creation and was trying to lock the folio. Thus causing a deadlock. In the first place, it is unexpected that folios/pages in the middle of writeback will be updated and become dirty. Nilfs2 adds a checksum to verify the validity of the log being written and uses it for recovery at mount, so data changes during writeback are suppressed. Since this is broken, an unclean shutdown could potentially cause recovery to fail. Investigation revealed that the root cause is that the wait for writeback completion in nilfs_page_mkwrite() is conditional, and if the backing device does not require stable writes, data may be modified without waiting. Fix these issues by making nilfs_page_mkwrite() wait for writeback to finish regardless of the stable write requirement of the backing device.

08 Apr '24

From: Jingxian He <hejingxian(a)huawei.com> hulk inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I9CC0X CVE: N/A ------------ Add bounce buffer feature for cvm guest os: 1) Cvm guest mapped memory is secure memory. 2) Qemu/kvm cannot access the secure memory. 3) Use bounce buffer as memory shared by cvm guest and qemu/kvm.

From: Johannes Berg <johannes.berg(a)intel.com> stable inclusion from stable-v5.15.149 commit 0c7478a2da3f5fe106b4658338873d50c86ac7ab category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9DNRR CVE: CVE-2023-52633 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit abe4eaa8618bb36c2b33e9cdde0499296a23448c ] In 'basic' time-travel mode (without =inf-cpu or =ext), we still get timer interrupts. These can happen at arbitrary points in time, i.e. while in timer_read(), which pushes time forward just a little bit. Then, if we happen to get the interrupt after calculating the new time to push to, but before actually finishing that, the interrupt will set the time to a value that's incompatible with the forward, and we'll crash because time goes backwards when we do the forwarding. Fix this by reading the time_travel_time, calculating the adjustment, and doing the adjustment all with interrupts disabled.

[PATCH OLK-5.10] perf/x86/lbr: Filter vsyscall addresses
by Luo Gengkun 08 Apr '24

08 Apr '24

From: JP Kobryn <inwardvessel(a)gmail.com> mainline inclusion from mainline-v6.6-rc6 commit e53899771a02f798d436655efbd9d4b46c0f9265 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I94P3R CVE: CVE-2023-52476 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- We found that a panic can occur when a vsyscall is made while LBR sampling is active. If the vsyscall is interrupted (NMI) for perf sampling, this call sequence can occur (most recent at top): __insn_get_emulate_prefix() insn_get_emulate_prefix() insn_get_prefixes() insn_get_opcode() decode_branch_type() get_branch_type() intel_pmu_lbr_filter() intel_pmu_handle_irq() perf_event_nmi_handler() Within __insn_get_emulate_prefix() at frame 0, a macro is called: peek_nbyte_next(insn_byte_t, insn, i) Within this macro, this dereference occurs: (insn)->next_byte Inspecting registers at this point, the value of the next_byte field is the address of the vsyscall made, for example the location of the vsyscall version of gettimeofday() at 0xffffffffff600000. The access to an address in the vsyscall region will trigger an oops due to an unhandled page fault. To fix the bug, filtering for vsyscalls can be done when determining the branch type. This patch will return a "none" branch if a kernel address if found to lie in the vsyscall region.

[PATCH OLK-5.10] bpf: fix check for attempt to corrupt spilled pointer
by Pu Lehui 08 Apr '24

08 Apr '24

From: Andrii Nakryiko <andrii(a)kernel.org> stable inclusion from stable-v5.10.209 commit 2757f17972d87773b3677777f5682510f13c66ef category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I93ED4 CVE: CVE-2023-52462 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit ab125ed3ec1c10ccc36bc98c7a4256ad114a3dae ] When register is spilled onto a stack as a 1/2/4-byte register, we set slot_type[BPF_REG_SIZE - 1] (plus potentially few more below it, depending on actual spill size).

[PATCH OLK-5.10] firmware: arm_scmi: Check mailbox/SMT channel for consistency
by Xiongfeng Wang 08 Apr '24

08 Apr '24

From: Cristian Marussi <cristian.marussi(a)arm.com> mainline inclusion from mainline-v6.8-rc2 commit 437a310b22244d4e0b78665c3042e5d1c0f45306 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I98BNA CVE: CVE-2023-52608 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit?i… -------------------------------- On reception of a completion interrupt the shared memory area is accessed to retrieve the message header at first and then, if the message sequence number identifies a transaction which is still pending, the related payload is fetched too. When an SCMI command times out the channel ownership remains with the platform until eventually a late reply is received and, as a consequence, any further transmission attempt remains pending, waiting for the channel to be relinquished by the platform. Once that late reply is received the channel ownership is given back to the agent and any pending request is then allowed to proceed and overwrite the SMT area of the just delivered late reply; then the wait for the reply to the new request starts. It has been observed that the spurious IRQ related to the late reply can be wrongly associated with the freshly enqueued request: when that happens the SCMI stack in-flight lookup procedure is fooled by the fact that the message header now present in the SMT area is related to the new pending transaction, even though the real reply has still to arrive. This race-condition on the A2P channel can be detected by looking at the channel status bits: a genuine reply from the platform will have set the channel free bit before triggering the completion IRQ. Add a consistency check to validate such condition in the A2P ISR.

[PATCH OLK-5.10] PCI: switchtec: Fix stdev_release() crash after surprise hot remove
by Xiongfeng Wang 08 Apr '24

08 Apr '24

From: Daniel Stodden <dns(a)arista.com> mainline inclusion from mainline-v6.8-rc1 commit df25461119d987b8c81d232cfe4411e91dcabe66 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I99JXH CVE: CVE-2023-52617 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit?i… -------------------------------- A PCI device hot removal may occur while stdev->cdev is held open. The call to stdev_release() then happens during close or exit, at a point way past switchtec_pci_remove(). Otherwise the last ref would vanish with the trailing put_device(), just before return. At that later point in time, the devm cleanup has already removed the stdev->mmio_mrpc mapping. Also, the stdev->pdev reference was not a counted one. Therefore, in DMA mode, the iowrite32() in stdev_release() will cause a fatal page fault, and the subsequent dma_free_coherent(), if reached, would pass a stale &stdev->pdev->dev pointer. Fix by moving MRPC DMA shutdown into switchtec_pci_remove(), after stdev_kill(). Counting the stdev->pdev ref is now optional, but may prevent future accidents.

[PATCH openEuler-1.0-LTS] sh: push-switch: Reorder cleanup operations to avoid use-after-free bug

07 Apr '24

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.")

[PATCH OLK-6.6] mm, fs: Add BPF_READAHEAD_OPTIMIZATION option for bpf readhead
by ZhaoLong Wang 07 Apr '24

07 Apr '24

hulk inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I7Y9JD CVE: NA --------------------------- This patch introduces a new configuration option called BPF_READAHEAD_OPTIMIZATION, which is designed to optimize the read performance in Spark SQL scenarios using eBPF to implement a programmable kernel. The changes include: - Add CONFIG_BPF_READAHEAD_OPTIMIZATION to mm/Kconfig, which depends on CONFIG_TRACEPOINTS. - Add conditional compilation directives to fs/ext4/file.c, fs/read_write.c, fs/xfs/xfs_file.c, and include/linux/fs.h to include tracepoint-related headers and functions only when BPF_READAHEAD_OPTIMIZATION is enabled. - Miodify page_cache_sync_ra() in mm/readahead.c to disable forced readahead when BPF_READAHEAD_OPTIMIZATION is not enabled.

[PATCH] [Huawei] iommu/arm-smmu-v3: fix using uninitialized or unchecked symbol
by Zhang Zekun 07 Apr '24

07 Apr '24

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I9EEIG -------------------------------------- This commit fix the following errors in the code: 1. The arm_smmu_aux_attach_dev function returns an uncertain return value ret when all conditions are not met. In this case, the cd table is not initialized. Therefore, a new default exception value is added. 2. In arm_smmu_ecmdq_probe(), the parameter pre_addr is used in the loop but it is not initialed yet. Also, the parameter "ecmdq" is used before check if it is NULL.

[PATCH OLK-6.6] mm, fs: Add BPF_READAHEAD_OPTIMIZATION option for bpf readhead
by ZhaoLong Wang 03 Apr '24

03 Apr '24

This patch introduces a new configuration option called BPF_READAHEAD_OPTIMIZATION, which is designed to optimize the read performance in Spark SQL scenarios using eBPF to implement a programmable kernel. The changes include: - Add CONFIG_BPF_READAHEAD_OPTIMIZATION to mm/Kconfig, which depends on CONFIG_TRACEPOINTS. - Add conditional compilation directives to fs/ext4/file.c, fs/read_write.c, fs/xfs/xfs_file.c, and include/linux/fs.h to include tracepoint-related headers and functions only when BPF_READAHEAD_OPTIMIZATION is enabled. - Miodify page_cache_sync_ra() in mm/readahead.c to disable forced readahead when BPF_READAHEAD_OPTIMIZATION is not enabled.

[PATCH OLK-6.6] ALSA: sh: aica: reorder cleanup operations to avoid UAF bugs
by liwei 03 Apr '24

03 Apr '24

From: Duoming Zhou <duoming(a)zju.edu.cn> mainline inclusion from mainline-v6.9-rc2 commit 051e0840ffa8ab25554d6b14b62c9ab9e4901457 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9DD86 CVE: CVE-2024-26654 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- The dreamcastcard->timer could schedule the spu_dma_work and the spu_dma_work could also arm the dreamcastcard->timer. When the snd_pcm_substream is closing, the aica_channel will be deallocated. But it could still be dereferenced in the worker thread. The reason is that del_timer() will return directly regardless of whether the timer handler is running or not and the worker could be rescheduled in the timer handler. As a result, the UAF bug will happen.

[PATCH OLK-5.10] ALSA: sh: aica: reorder cleanup operations to avoid UAF bugs
by liwei 03 Apr '24

03 Apr '24

From: Duoming Zhou <duoming(a)zju.edu.cn> mainline inclusion from mainline-v6.9-rc2 commit 051e0840ffa8ab25554d6b14b62c9ab9e4901457 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9DD86 CVE: CVE-2024-26654 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- The dreamcastcard->timer could schedule the spu_dma_work and the spu_dma_work could also arm the dreamcastcard->timer. When the snd_pcm_substream is closing, the aica_channel will be deallocated. But it could still be dereferenced in the worker thread. The reason is that del_timer() will return directly regardless of whether the timer handler is running or not and the worker could be rescheduled in the timer handler. As a result, the UAF bug will happen. The racy situation is shown below: (Thread 1) | (Thread 2) snd_aicapcm_pcm_close() | ... | run_spu_dma() //worker | mod_timer() flush_work() | del_timer() | aica_period_elapsed() //timer kfree(dreamcastcard->channel) | schedule_work() | run_spu_dma() //worker ... | dreamcastcard->channel-> //USE In order to mitigate this bug and other possible corner cases, call mod_timer() conditionally in run_spu_dma(), then implement PCM sync_stop op to cancel both the timer and worker.

BTRFS: error (device vdc: state EA) in cleanup_transaction:2055: errno=-2 No such entry This happens because create_pending_snapshot() initializes the new root item as a copy of the source root item. This includes the refs field, which is 0 for a deleted subvolume. The call to btrfs_insert_root() therefore inserts a root with refs == 0. btrfs_get_new_fs_root() then finds the root and returns -ENOENT if refs == 0, which causes create_pending_snapshot() to abort. Fix it by checking the source root's refs before attempting the snapshot, but after locking subvol_sem to avoid racing with deletion.

[PATCH openEuler-1.0-LTS] scsi: hisi_sas: Update disk locked timeout to 7 seconds
by Xingui Yang 03 Apr '24

03 Apr '24

driver inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I9DOVK CVE: NA --------------------------------------------------------------------------- The sata disk will be locked after the disk sends the DMA Setup frame until all data frame transmission is completed. The CFG_ICT_TIMER_STEP_TRSH register is used for sata disk to configure the step size of the timer which records the time when the disk is locked. The unit is 1us and the default step size is 150ms. If the disk is locked for more than 7 timer steps, the io to be sent to the disk will end abnormally. The current timeout is only about 1 second, it is easy to trigger IO abnormal end when the SATA hard disk returns data slowly. Adjust the timeout to 7 seconds based on ERC time of most disks.

If the work queue is schedule to run after the TIPC module is removed, kernel will crash as the work queue function cleanup_beareri() code no longer exists when trying to invoke it. To fix it, this patch introduce a member wq_count in tipc_net to track the numbers of work queues in schedule, and wait and exit until all work queues are done in tipc_exit_net().

[PATCH openEuler-1.0-LTS] tipc: skb_linearize the head skb when reassembling msgs
by Ziyang Xuan 01 Apr '24

01 Apr '24

From: Xin Long <lucien.xin(a)gmail.com> stable inclusion from stable-v4.19.193 commit 4b1761898861117c97066aea6c58f68a7787f0bf category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9BHF9 CVE: CVE-2021-47162 -------------------------------- commit b7df21cf1b79ab7026f545e7bf837bd5750ac026 upstream. It's not a good idea to append the frag skb to a skb's frag_list if the frag_list already has skbs from elsewhere, such as this skb was created by pskb_copy() where the frag_list was cloned (all the skbs in it were skb_get'ed) and shared by multiple skbs. However, the new appended frag skb should have been only seen by the current skb. Otherwise, it will cause use after free crashes as this appended frag skb are seen by multiple skbs but it only got skb_get called once. The same thing happens with a skb updated by pskb_may_pull() with a skb_cloned skb. Li Shuang has reported quite a few crashes caused by this when doing testing over macvlan devices: [] kernel BUG at net/core/skbuff.c:1970! [] Call Trace: [] skb_clone+0x4d/0xb0 [] macvlan_broadcast+0xd8/0x160 [macvlan] [] macvlan_process_broadcast+0x148/0x150 [macvlan] [] process_one_work+0x1a7/0x360 [] worker_thread+0x30/0x390 [] kernel BUG at mm/usercopy.c:102!

This patch is to fix it by linearizing the head skb if it has frag_list set in tipc_buf_append(). Note that we choose to do this before calling skb_unshare(), as __skb_linearize() will avoid skb_copy(). Also, we can not just drop the frag_list either as the early time.

[PATCH openEuler-1.0-LTS] USB: usbfs: Don't WARN about excessively large memory allocations
by Yu Liao 01 Apr '24

From: Alan Stern <stern(a)rowland.harvard.edu> stable inclusion from stable-v4.19.193 commit 2ab21d6e1411999b5fb43434f421f00bf50002eb category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9BHQL CVE: CVE-2021-47170 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 4f2629ea67e7225c3fd292c7fe4f5b3c9d6392de upstream. Syzbot found that the kernel generates a WARNing if the user tries to submit a bulk transfer through usbfs with a buffer that is way too large. This isn't a bug in the kernel; it's merely an invalid request from the user and the usbfs code does handle it correctly. In theory the same thing can happen with async transfers, or with the packet descriptor table for isochronous transfers. To prevent the MM subsystem from complaining about these bad allocation requests, add the __GFP_NOWARN flag to the kmalloc calls for these buffers.

[PATCH OLK-5.10] cpufreq: CPPC: Eliminate the impact of cpc_read() latency error
by Zeng Heng 30 Mar '24

30 Mar '24

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I9COT9 ----------------------------- We have found significant differences in the latency of cpc_read() between regular scenarios and scenarios with high memory access pressure. Ignoring this error can result in getting rate interface occasionally returning absurd values. Here provides a high memory access sample test by stress-ng. My local testing platform includes 160 CPUs, the CPC registers is accessed by mmio method, and the cpuidle feature is disabled (the AMU always works online): ~~~ ./stress-ng --memrate 160 --timeout 180 ~~~ The following data is sourced from ftrace statistics towards cppc_get_perf_ctrs(): Regular scenarios || High memory access pressure scenarios 104) | cppc_get_perf_ctrs() { || 133) | cppc_get_perf_ctrs() { 104) 0.800 us | cpc_read.isra.0(); || 133) 4.580 us | cpc_read.isra.0(); 104) 0.640 us | cpc_read.isra.0(); || 133) 7.780 us | cpc_read.isra.0(); 104) 0.450 us | cpc_read.isra.0(); || 133) 2.550 us | cpc_read.isra.0(); 104) 0.430 us | cpc_read.isra.0(); || 133) 0.570 us | cpc_read.isra.0(); 104) 4.610 us | } || 133) ! 157.610 us | } 104) | cppc_get_perf_ctrs() { || 133) | cppc_get_perf_ctrs() { 104) 0.720 us | cpc_read.isra.0(); || 133) 0.760 us | cpc_read.isra.0(); 104) 0.720 us | cpc_read.isra.0(); || 133) 4.480 us | cpc_read.isra.0(); 104) 0.510 us | cpc_read.isra.0(); || 133) 0.520 us | cpc_read.isra.0(); 104) 0.500 us | cpc_read.isra.0(); || 133) + 10.100 us | cpc_read.isra.0(); 104) 3.460 us | } || 133) ! 120.850 us | } 108) | cppc_get_perf_ctrs() { || 87) | cppc_get_perf_ctrs() { 108) 0.820 us | cpc_read.isra.0(); || 87) ! 255.200 us | cpc_read.isra.0(); 108) 0.850 us | cpc_read.isra.0(); || 87) 2.910 us | cpc_read.isra.0(); 108) 0.590 us | cpc_read.isra.0(); || 87) 5.160 us | cpc_read.isra.0(); 108) 0.610 us | cpc_read.isra.0(); || 87) 4.340 us | cpc_read.isra.0(); 108) 5.080 us | } || 87) ! 315.790 us | } 108) | cppc_get_perf_ctrs() { || 87) | cppc_get_perf_ctrs() { 108) 0.630 us | cpc_read.isra.0(); || 87) 0.800 us | cpc_read.isra.0(); 108) 0.630 us | cpc_read.isra.0(); || 87) 6.310 us | cpc_read.isra.0(); 108) 0.420 us | cpc_read.isra.0(); || 87) 1.190 us | cpc_read.isra.0(); 108) 0.430 us | cpc_read.isra.0(); || 87) + 11.620 us | cpc_read.isra.0(); 108) 3.780 us | } || 87) ! 207.010 us | } My local testing platform works under 3000000hz, but the cpuinfo_cur_freq interface returns values that are not even close to the actual frequency: [root@localhost ~]# cd /sys/devices/system/cpu [root@localhost cpu]# for i in {0..159}; do cat cpu$i/cpufreq/cpuinfo_cur_freq; done 5127812 2952127 3069001 3496183 922989768 2419194 3427042 2331869 3594611 8238499 ... The reason is when under heavy memory access pressure, the execution of cpc_read() delay has increased from sub-microsecond to several hundred microseconds. Moving the cpc_read function into a critical section by irq disable/enable has minimal impact on the result. cppc_get_perf_ctrs()[0] cppc_get_perf_ctrs()[1] / \ / \ cpc_read cpc_read cpc_read cpc_read ref[0] delivered[0] ref[1] delivered[1] | | | | v v v v -----------------------------------------------------------------------> time <--delta[0]--> <------sample_period------> <-----delta[1]-----> Since that, freq = ref_freq * (delivered[1] - delivered[0]) / (ref[1] - ref[0]) and delivered[1] - delivered[0] = freq * (delta[1] + sample_period), ref[1] - ref[0] = ref_freq * (delta[0] + sample_period) To eliminate the impact of system memory access latency, setting a sampling period of 2us is far from sufficient. Consequently, we suggest cppc_cpufreq_get_rate() only can be called in the process context, and adopt a longer sampling period to neutralize the impact of random latency. Here we call the cond_resched() function instead of sleep-like functions to ensure that `taskset -c $i cat cpu$i/cpufreq/cpuinfo_cur_freq` could work when cpuidle feature is enabled.

[PATCH OLK-6.6] userfaultfd: early return in dup_userfaultfd()

29 Mar '24

From: ZhangPeng <zhangpeng362(a)huawei.com> maillist inclusion category: performance bugzilla: https://gitee.com/openeuler/kernel/issues/I9CKXN CVE: NA Reference: https://lore.kernel.org/all/20240327090835.3232629-1-zhangpeng362@huawei.co… -------------------------------- When vma->vm_userfaultfd_ctx.ctx is NULL, vma->vm_flags should have cleared __VM_UFFD_FLAGS. Therefore, there is no need to down_write or clear the flag, which will affect fork performance. Fix this by returning early if octx is NULL in dup_userfaultfd().

[PATCH OLK-6.6 v3 00/18] Mitigate a vmap lock contention
by Peng Zhang 29 Mar '24

29 Mar '24

From: ZhangPeng <zhangpeng362(a)huawei.com> This patch set includes two patch sets: Mitigate a vmap lock contention and mm/vmalloc: lock contention optimization under multi-threading. In high-concurrency scenarios such as the "/test_vmalloc.sh run_test_mask=7 nr_threads=64" scenario, the performance is improved by more than 10x. The run time was reduced from 18m45.268s to 1m45.066s. Changelog: v2->v3: - Fix commit format warning v1->v2: - Remove 2 maillist inclusion patches - Merge patch 21 to resolve the conflict in patch 16 Alexei Starovoitov (3): mm: Enforce VM_IOREMAP flag and range in ioremap_page_range. mm: Introduce VM_SPARSE kind and vm_area_[un]map_pages(). mm: Introduce vmap_page_range() to map pages in PCI address space Baoquan He (2): mm/vmalloc: fix the unchecked dereference warning in vread_iter() mm/vmalloc: remove vmap_area_list Uladzislau Rezki (Sony) (13): mm: vmalloc: add va_alloc() helper mm: vmalloc: rename adjust_va_to_fit_type() function mm: vmalloc: move vmap_init_free_space() down in vmalloc.c mm: vmalloc: remove global vmap_area_root rb-tree mm: vmalloc: remove global purge_vmap_area_root rb-tree mm: vmalloc: offload free_vmap_area_lock lock mm: vmalloc: add a scan area of VA only once mm: vmalloc: support multiple nodes in vread_iter mm: vmalloc: support multiple nodes in vmallocinfo mm: vmalloc: set nr_nodes based on CPUs in a system mm: vmalloc: add a shrinker to drain vmap pools mm: vmalloc: improve description of vmap node layer mm: vmalloc: refactor vmalloc_dump_obj() function .../admin-guide/kdump/vmcoreinfo.rst | 8 +- arch/arm/mm/ioremap.c | 8 +- arch/arm64/kernel/crash_core.c | 1 - arch/loongarch/kernel/setup.c | 2 +- arch/mips/loongson64/init.c | 2 +- arch/powerpc/kernel/isa-bridge.c | 4 +- arch/riscv/kernel/crash_core.c | 1 - drivers/pci/pci.c | 4 +- include/linux/io.h | 7 + include/linux/vmalloc.h | 6 +- kernel/crash_core.c | 4 +- kernel/kallsyms_selftest.c | 1 - mm/nommu.c | 2 - mm/vmalloc.c | 1156 +++++++++++++---- 14 files changed, 914 insertions(+), 292 deletions(-) -- 2.25.1

[PATCH openEuler-1.0-LTS] i2c: i801: Don't generate an interrupt on bus reset
by Li Huafei 28 Mar '24

28 Mar '24

From: Jean Delvare <jdelvare(a)suse.de> stable inclusion from stable-v4.19.193 commit c70e1ba2e7e65255a0ce004f531dd90dada97a8c category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9BGWP CVE: CVE-2021-47153 --------------------------- commit e4d8716c3dcec47f1557024add24e1f3c09eb24b upstream. Now that the i2c-i801 driver supports interrupts, setting the KILL bit in a attempt to recover from a timed out transaction triggers an interrupt. Unfortunately, the interrupt handler (i801_isr) is not prepared for this situation and will try to process the interrupt as if it was signaling the end of a successful transaction. In the case of a block transaction, this can result in an out-of-range memory access. This condition was reproduced several times by syzbot: https://syzkaller.appspot.com/bug?extid=ed71512d469895b5b34e https://syzkaller.appspot.com/bug?extid=8c8dedc0ba9e03f6c79e https://syzkaller.appspot.com/bug?extid=c8ff0b6d6c73d81b610e https://syzkaller.appspot.com/bug?extid=33f6c360821c399d69eb https://syzkaller.appspot.com/bug?extid=be15dc0b1933f04b043a https://syzkaller.appspot.com/bug?extid=b4d3fd1dfd53e90afd79 So disable interrupts while trying to reset the bus.

[PATCH OLK-6.6] irqchip/gic-v3: Fix a system stall when using pseudo NMI with CONFIG_ARM64_NMI closed
by Jinjie Ruan 28 Mar '24

28 Mar '24

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I9CHAE -------------------------------- A system stall occurrs when using pseudo NMI with CONFIG_ARM64_NMI closed. If the hardware supports FEAT_NMI, the ALLINT bit in pstate may set or clear on exception trap whether the software enables it or not, so it is not safe to use it to check interrupts_enabled() or fast_interrupts_enabled() when FEAT_NMI not enabled in kernel, so recover it. After applying this patch, the system stall not happen again on hardware with FEAT_NMI feature.

[PATCH OLK-5.10 v4 0/2] Fix I/O high when memory almost met memcg limit
by Liu Shixin 28 Mar '24

28 Mar '24

Recently, when install package in a docker which almost reached its memory limit, the installer has no respond severely for more than 15 minutes. During this period, I/O stays high(~1G/s) and influence the whole machine. I've constructed a use case as follows: 1. create a docker: $ cat test.sh #!/bin/bash docker rm centos7 --force docker create --name centos7 --memory 4G --memory-swap 6G centos:7 /usr/sbin/init docker start centos7 sleep 1 docker cp ./alloc_page centos7:/ docker cp ./reproduce.sh centos7:/ docker exec -it centos7 /bin/bash 2. try reproduce the problem in docker: $ cat reproduce.sh #!/bin/bash while true; do flag=$(ps -ef | grep -v grep | grep alloc_page| wc -l) if [ "$flag" -eq 0 ]; then /alloc_page & fi sleep 30 start_time=$(date +%s) yum install -y expect > /dev/null 2>&1 end_time=$(date +%s) elapsed_time=$((end_time - start_time)) echo "$elapsed_time seconds" yum remove -y expect > /dev/null 2>&1 done $ cat alloc_page.c: #include <stdio.h> #include <stdlib.h> #include <unistd.h> #include <string.h> #define SIZE 1*1024*1024 //1M int main() { void *addr = NULL; int i; for (i = 0; i < 1024 * 6 - 50;i++) { addr = (void *)malloc(SIZE); if (!addr) return -1; memset(addr, 0, SIZE); } sleep(99999); return 0; } We found that this problem is caused by a lot ot meaningless read-ahead. Since the docker is almost met memory limit, the page will be reclaimed immediately after read-ahead and will read-ahead again immediately. The program is executed slowly and waste a lot of I/O resource. These patches aim to break the read-ahead in above scenario.
