[PATCH openEuler-1.0-LTS] scsi: hisi_sas: Update disk locked timeout to 7 seconds
by Xingui Yang 09 Apr '24

09 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.

[PATCH OLK-5.10] net/sched: act_mirred: use the backlog for mirred ingress
by Zhengchao Shao 09 Apr '24

09 Apr '24

From: Jakub Kicinski <kuba(a)kernel.org> mainline inclusion from mainline-v6.8-rc6 commit 52f671db18823089a02f07efc04efdb2272ddc17 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9E2LT CVE: CVE-2024-26740 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- The test Davide added in commit ca22da2fbd69 ("act_mirred: use the backlog for nested calls to mirred ingress") hangs our testing VMs every 10 or so runs, with the familiar tcp_v4_rcv -> tcp_v4_rcv deadlock reported by lockdep. The problem as previously described by Davide (see Link) is that if we reverse flow of traffic with the redirect (egress -> ingress) we may reach the same socket which generated the packet. And we may still be holding its socket lock. The common solution to such deadlocks is to put the packet in the Rx backlog, rather than run the Rx path inline. Do that for all egress -> ingress reversals, not just once we started to nest mirred calls. In the past there was a concern that the backlog indirection will lead to loss of error reporting / less accurate stats. But the current workaround does not seem to address the issue.

[PATCH OLK-6.6] irqdomain: Fix driver re-inserting failures when IRQs not being freed
by Jie Zhan 09 Apr '24

09 Apr '24

driver inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I9ERMB ------------------------------------------------------------------------ Since commit 4615fbc3788d ("genirq/irqdomain: Don't try to free an interrupt that has no mapping"), we have found failures when re-inserting some specific drivers: [root@localhost ~]# rmmod hisi_sas_v3_hw [root@localhost ~]# modprobe hisi_sas_v3_hw [ 1295.622525] hisi_sas_v3_hw: probe of 0000:30:04.0 failed with error -2 A relevant discussion can be found at: https://lore.kernel.org/lkml/3d3d0155e66429968cb4f6b4feeae4b3@kernel.org/ This is because IRQs from a low-level domain are not freed together, leaving some leaked. Thus, the next driver insertion fails to allocate the same number of IRQs. Free a contiguous group of IRQs in one go to fix this issue.

[PATCH OLK-5.10 1/4] kvm: add cvm host feature
by hejingxian 08 Apr '24

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 host support for Confidential VMs: 1. Add new kvm_type for cvm. 2. Init cvm related data while user create vm with cvm type. 3. Add cvm hypervisor while run in sel2 which named tmm. 4. Kvm call tmm interface to create cvm stage2 pagetable and run cvm.

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.

[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: https://gitee.com/src-openeuler/kernel/issues/I9E2EQ 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.

[PATCH openEuler-1.0-LTS] 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

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.
