The root cause of the issue is that the function drm_sched_fini is called before drm_sched_entity_kill. In drm_sched_fini, the drm_sched_rq structure is freed, but this structure is later accessed by each entity within the run queue, leading to invalid memory access. To resolve this, the order of cleanup calls is updated: Before: amdgpu_fence_driver_sw_fini amdgpu_device_ip_fini After: amdgpu_device_ip_fini amdgpu_fence_driver_sw_fini This updated order ensures that all entities in the IPs are cleaned up first, followed by proper cleanup of the schedulers. Additional Investigation: During debugging, another issue was identified in the amdgpu_vce_sw_fini function. The vce.vcpu_bo buffer must be freed only as the final step in the cleanup process to prevent any premature access during earlier cleanup stages. v2: Using Christian suggestion call drm_sched_entity_destroy before drm_sched_fini.

[PATCH OLK-5.10] iommu/arm-smmu: Defer probe of clients after smmu device bound
by Zhang Zekun 18 Feb '25

18 Feb '25

From: Pratyush Brahma <quic_pbrahma(a)quicinc.com> stable inclusion from stable-v5.10.231 commit c2527d07c7e9cda2c6165d5edccf74752baac1b0 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBEAME CVE: CVE-2024-56568 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 229e6ee43d2a160a1592b83aad620d6027084aad upstream. Null pointer dereference occurs due to a race between smmu driver probe and client driver probe, when of_dma_configure() for client is called after the iommu_device_register() for smmu driver probe has executed but before the driver_bound() for smmu driver has been called.

[PATCH OLK-5.10] usb: typec: altmode should keep reference to parent

18 Feb '25

From: Thadeu Lima de Souza Cascardo <cascardo(a)igalia.com> stable inclusion from stable-v5.10.229 commit 6af43ec3bf40f8b428d9134ffa7a291aecd60da8 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IB2SU4 CVE: CVE-2024-50150 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… ------------------------------------------------------------------ [ Upstream commit befab3a278c59db0cc88c8799638064f6d3fd6f8 ] The altmode device release refers to its parent device, but without keeping a reference to it. When registering the altmode, get a reference to the parent and put it in the release function. Before this fix, when using CONFIG_DEBUG_KOBJECT_RELEASE, we see issues like this: [ 43.572860] kobject: 'port0.0' (ffff8880057ba008): kobject_release, parent 0000000000000000 (delayed 3000) [ 43.573532] kobject: 'port0.1' (ffff8880057bd008): kobject_release, parent 0000000000000000 (delayed 1000) [ 43.574407] kobject: 'port0' (ffff8880057b9008): kobject_release, parent 0000000000000000 (delayed 3000) [ 43.575059] kobject: 'port1.0' (ffff8880057ca008): kobject_release, parent 0000000000000000 (delayed 4000) [ 43.575908] kobject: 'port1.1' (ffff8880057c9008): kobject_release, parent 0000000000000000 (delayed 4000) [ 43.576908] kobject: 'typec' (ffff8880062dbc00): kobject_release, parent 0000000000000000 (delayed 4000) [ 43.577769] kobject: 'port1' (ffff8880057bf008): kobject_release, parent 0000000000000000 (delayed 3000) [ 46.612867] ================================================================== [ 46.613402] BUG: KASAN: slab-use-after-free in typec_altmode_release+0x38/0x129 [ 46.614003] Read of size 8 at addr ffff8880057b9118 by task kworker/2:1/48 [ 46.614538] [ 46.614668] CPU: 2 UID: 0 PID: 48 Comm: kworker/2:1 Not tainted 6.12.0-rc1-00138-gedbae730ad31 #535 [ 46.615391] Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 1.15.0-1 04/01/2014 [ 46.616042] Workqueue: events kobject_delayed_cleanup [ 46.616446] Call Trace: [ 46.616648] <TASK> [ 46.616820] dump_stack_lvl+0x5b/0x7c [ 46.617112] ?

[PATCH openEuler-1.0-LTS] xsk: fix OOB map writes when deleting elements
by Wang Liang 18 Feb '25

18 Feb '25

From: Maciej Fijalkowski <maciej.fijalkowski(a)intel.com> mainline inclusion from mainline-v6.13-rc2 commit 32cd3db7de97c0c7a018756ce66244342fd583f0 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBEAPK CVE: CVE-2024-56614 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Jordy says: " In the xsk_map_delete_elem function an unsigned integer (map->max_entries) is compared with a user-controlled signed integer (k). Due to implicit type conversion, a large unsigned value for map->max_entries can bypass the intended bounds check: if (k >= map->max_entries) return -EINVAL; This allows k to hold a negative value (between -2147483648 and -2), which is then used as an array index in m->xsk_map[k], which results in an out-of-bounds access. spin_lock_bh(&m->lock); map_entry = &m->xsk_map[k]; // Out-of-bounds map_entry old_xs = unrcu_pointer(xchg(map_entry, NULL)); // Oob write if (old_xs) xsk_map_sock_delete(old_xs, map_entry); spin_unlock_bh(&m->lock); The xchg operation can then be used to cause an out-of-bounds write. Moreover, the invalid map_entry passed to xsk_map_sock_delete can lead to further memory corruption. " It indeed results in following splat: [76612.897343] BUG: unable to handle page fault for address: ffffc8fc2e461108 [76612.904330] #PF: supervisor write access in kernel mode [76612.909639] #PF: error_code(0x0002) - not-present page [76612.914855] PGD 0 P4D 0 [76612.917431] Oops: Oops: 0002 [#1] PREEMPT SMP [76612.921859] CPU: 11 UID: 0 PID: 10318 Comm: a.out Not tainted 6.12.0-rc1+ #470 [76612.929189] Hardware name: Intel Corporation S2600WFT/S2600WFT, BIOS SE5C620.86B.02.01.0008.031920191559 03/19/2019 [76612.939781] RIP: 0010:xsk_map_delete_elem+0x2d/0x60 [76612.944738] Code: 00 00 41 54 55 53 48 63 2e 3b 6f 24 73 38 4c 8d a7 f8 00 00 00 48 89 fb 4c 89 e7 e8 2d bf 05 00 48 8d b4 eb 00 01 00 00 31 ff <48> 87 3e 48 85 ff 74 05 e8 16 ff ff ff 4c 89 e7 e8 3e bc 05 00 31 [76612.963774] RSP: 0018:ffffc9002e407df8 EFLAGS: 00010246 [76612.969079] RAX: 0000000000000000 RBX: ffffc9002e461000 RCX: 0000000000000000 [76612.976323] RDX: 0000000000000001 RSI: ffffc8fc2e461108 RDI: 0000000000000000 [76612.983569] RBP: ffffffff80000001 R08: 0000000000000000 R09: 0000000000000007 [76612.990812] R10: ffffc9002e407e18 R11: ffff888108a38858 R12: ffffc9002e4610f8 [76612.998060] R13: ffff888108a38858 R14: 00007ffd1ae0ac78 R15: ffffc9002e4610c0 [76613.005303] FS: 00007f80b6f59740(0000) GS:ffff8897e0ec0000(0000) knlGS:0000000000000000 [76613.013517] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [76613.019349] CR2: ffffc8fc2e461108 CR3: 000000011e3ef001 CR4: 00000000007726f0 [76613.026595] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 [76613.033841] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 [76613.041086] PKRU: 55555554 [76613.043842] Call Trace: [76613.046331] <TASK> [76613.048468] ? __die+0x20/0x60 [76613.051581] ? page_fault_oops+0x15a/0x450 [76613.055747] ? search_extable+0x22/0x30 [76613.059649] ? search_bpf_extables+0x5f/0x80 [76613.063988] ? exc_page_fault+0xa9/0x140 [76613.067975] ? asm_exc_page_fault+0x22/0x30 [76613.072229] ? xsk_map_delete_elem+0x2d/0x60 [76613.076573] ? xsk_map_delete_elem+0x23/0x60 [76613.080914] __sys_bpf+0x19b7/0x23c0 [76613.084555] __x64_sys_bpf+0x1a/0x20 [76613.088194] do_syscall_64+0x37/0xb0 [76613.091832] entry_SYSCALL_64_after_hwframe+0x4b/0x53 [76613.096962] RIP: 0033:0x7f80b6d1e88d [76613.100592] Code: 5b 41 5c c3 66 0f 1f 84 00 00 00 00 00 f3 0f 1e fa 48 89 f8 48 89 f7 48 89 d6 48 89 ca 4d 89 c2 4d 89 c8 4c 8b 4c 24 08 0f 05 <48> 3d 01 f0 ff ff 73 01 c3 48 8b 0d 73 b5 0f 00 f7 d8 64 89 01 48 [76613.119631] RSP: 002b:00007ffd1ae0ac68 EFLAGS: 00000206 ORIG_RAX: 0000000000000141 [76613.131330] RAX: ffffffffffffffda RBX: 0000000000000000 RCX: 00007f80b6d1e88d [76613.142632] RDX: 0000000000000098 RSI: 00007ffd1ae0ad20 RDI: 0000000000000003 [76613.153967] RBP: 00007ffd1ae0adc0 R08: 0000000000000000 R09: 0000000000000000 [76613.166030] R10: 00007f80b6f77040 R11: 0000000000000206 R12: 00007ffd1ae0aed8 [76613.177130] R13: 000055ddf42ce1e9 R14: 000055ddf42d0d98 R15: 00007f80b6fab040 [76613.188129] </TASK> Fix this by simply changing key type from int to u32.

[PATCH OLK-5.10] comedi: Flush partial mappings in error case
by Chen Ridong 17 Feb '25

17 Feb '25

From: Jann Horn <jannh(a)google.com> stable inclusion from stable-v5.10.231 commit b9322408d83accc8b96322bc7356593206288c56 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBDHGS CVE: CVE-2024-53148 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit ce8f9fb651fac95dd41f69afe54d935420b945bd upstream. If some remap_pfn_range() calls succeeded before one failed, we still have buffer pages mapped into the userspace page tables when we drop the buffer reference with comedi_buf_map_put(bm). The userspace mappings are only cleaned up later in the mmap error path. Fix it by explicitly flushing all mappings in our VMA on the error path. See commit 79a61cc3fc04 ("mm: avoid leaving partial pfn mappings around in error case").

[PATCH OLK-6.6] ALSA: seq: oss: Fix races at processing SysEx messages
by Gu Bowen 17 Feb '25

17 Feb '25

From: Takashi Iwai <tiwai(a)suse.de> stable inclusion from stable-v6.6.70 commit d2392b79d8af3714ea8878b71c66dc49d3110f44 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBID2T CVE: CVE-2024-57893 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 0179488ca992d79908b8e26b9213f1554fc5bacc upstream. OSS sequencer handles the SysEx messages split in 6 bytes packets, and ALSA sequencer OSS layer tries to combine those. It stores the data in the internal buffer and this access is racy as of now, which may lead to the out-of-bounds access. As a temporary band-aid fix, introduce a mutex for serializing the process of the SysEx message packets.

[PATCH OLK-5.10] iomap: avoid avoid truncating 64-bit offset to 32 bits
by Long Li 17 Feb '25

From: Marco Nelissen <marco.nelissen(a)gmail.com> mainline inclusion from mainline-v6.10-rc2 commit c13094b894de289514d84b8db56d1f2931a0bade category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBJXF0 CVE: CVE-2025-21667 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- on 32-bit kernels, iomap_write_delalloc_scan() was inadvertently using a 32-bit position due to folio_next_index() returning an unsigned long.

[PATCH OLK-6.6] KVM: arm64: Get rid of userspace_irqchip_in_use
by Zhao Yipeng 17 Feb '25

17 Feb '25

From: Raghavendra Rao Ananta <rananta(a)google.com> stable inclusion from stable-v6.6.64 commit dd2f9861f27571d47998d71e7516bf7216db0b52 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBEADT CVE: CVE-2024-53195 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- KVM: arm64: Get rid of userspace_irqchip_in_use commit 38d7aacca09230fdb98a34194fec2af597e8e20d upstream. Improper use of userspace_irqchip_in_use led to syzbot hitting the following WARN_ON() in kvm_timer_update_irq(): WARNING: CPU: 0 PID: 3281 at arch/arm64/kvm/arch_timer.c:459 kvm_timer_update_irq+0x21c/0x394 Call trace: kvm_timer_update_irq+0x21c/0x394 arch/arm64/kvm/arch_timer.c:459 kvm_timer_vcpu_reset+0x158/0x684 arch/arm64/kvm/arch_timer.c:968 kvm_reset_vcpu+0x3b4/0x560 arch/arm64/kvm/reset.c:264 kvm_vcpu_set_target arch/arm64/kvm/arm.c:1553 [inline] kvm_arch_vcpu_ioctl_vcpu_init arch/arm64/kvm/arm.c:1573 [inline] kvm_arch_vcpu_ioctl+0x112c/0x1b3c arch/arm64/kvm/arm.c:1695 kvm_vcpu_ioctl+0x4ec/0xf74 virt/kvm/kvm_main.c:4658 vfs_ioctl fs/ioctl.c:51 [inline] __do_sys_ioctl fs/ioctl.c:907 [inline] __se_sys_ioctl fs/ioctl.c:893 [inline] __arm64_sys_ioctl+0x108/0x184 fs/ioctl.c:893 __invoke_syscall arch/arm64/kernel/syscall.c:35 [inline] invoke_syscall+0x78/0x1b8 arch/arm64/kernel/syscall.c:49 el0_svc_common+0xe8/0x1b0 arch/arm64/kernel/syscall.c:132 do_el0_svc+0x40/0x50 arch/arm64/kernel/syscall.c:151 el0_svc+0x54/0x14c arch/arm64/kernel/entry-common.c:712 el0t_64_sync_handler+0x84/0xfc arch/arm64/kernel/entry-common.c:730 el0t_64_sync+0x190/0x194 arch/arm64/kernel/entry.S:598 The following sequence led to the scenario: - Userspace creates a VM and a vCPU. - The vCPU is initialized with KVM_ARM_VCPU_PMU_V3 during KVM_ARM_VCPU_INIT. - Without any other setup, such as vGIC or vPMU, userspace issues KVM_RUN on the vCPU. Since the vPMU is requested, but not setup, kvm_arm_pmu_v3_enable() fails in kvm_arch_vcpu_run_pid_change(). As a result, KVM_RUN returns after enabling the timer, but before incrementing 'userspace_irqchip_in_use': kvm_arch_vcpu_run_pid_change() ret = kvm_arm_pmu_v3_enable() if (!vcpu->arch.pmu.created) return -EINVAL; if (ret) return ret; [...] if (!irqchip_in_kernel(kvm)) static_branch_inc(&userspace_irqchip_in_use); - Userspace ignores the error and issues KVM_ARM_VCPU_INIT again. Since the timer is already enabled, control moves through the following flow, ultimately hitting the WARN_ON(): kvm_timer_vcpu_reset() if (timer->enabled) kvm_timer_update_irq() if (!userspace_irqchip()) ret = kvm_vgic_inject_irq() ret = vgic_lazy_init() if (unlikely(!vgic_initialized(kvm))) if (kvm->arch.vgic.vgic_model != KVM_DEV_TYPE_ARM_VGIC_V2) return -EBUSY; WARN_ON(ret); Theoretically, since userspace_irqchip_in_use's functionality can be simply replaced by '!irqchip_in_kernel()', get rid of the static key to avoid the mismanagement, which also helps with the syzbot issue.

[PATCH OLK-6.6] mm: resolve faulty mmap_region() error path behaviour
by Wupeng Ma 17 Feb '25

17 Feb '25

From: Lorenzo Stoakes <lorenzo.stoakes(a)oracle.com> stable inclusion from stable-v6.6.63 commit bdc136e2b05fabcd780fe5f165d154eb779dfcb0 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IB7051 CVE: CVE-2024-53096 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 5de195060b2e251a835f622759550e6202167641 ] The mmap_region() function is somewhat terrifying, with spaghetti-like control flow and numerous means by which issues can arise and incomplete state, memory leaks and other unpleasantness can occur. A large amount of the complexity arises from trying to handle errors late in the process of mapping a VMA, which forms the basis of recently observed issues with resource leaks and observable inconsistent state. Taking advantage of previous patches in this series we move a number of checks earlier in the code, simplifying things by moving the core of the logic into a static internal function __mmap_region(). Doing this allows us to perform a number of checks up front before we do any real work, and allows us to unwind the writable unmap check unconditionally as required and to perform a CONFIG_DEBUG_VM_MAPLE_TREE validation unconditionally also. We move a number of things here: 1. We preallocate memory for the iterator before we call the file-backed memory hook, allowing us to exit early and avoid having to perform complicated and error-prone close/free logic. We carefully free iterator state on both success and error paths. 2. The enclosing mmap_region() function handles the mapping_map_writable() logic early. Previously the logic had the mapping_map_writable() at the point of mapping a newly allocated file-backed VMA, and a matching mapping_unmap_writable() on success and error paths. We now do this unconditionally if this is a file-backed, shared writable mapping. If a driver changes the flags to eliminate VM_MAYWRITE, however doing so does not invalidate the seal check we just performed, and we in any case always decrement the counter in the wrapper. We perform a debug assert to ensure a driver does not attempt to do the opposite. 3. We also move arch_validate_flags() up into the mmap_region() function. This is only relevant on arm64 and sparc64, and the check is only meaningful for SPARC with ADI enabled. We explicitly add a warning for this arch if a driver invalidates this check, though the code ought eventually to be fixed to eliminate the need for this. With all of these measures in place, we no longer need to explicitly close the VMA on error paths, as we place all checks which might fail prior to a call to any driver mmap hook. This eliminates an entire class of errors, makes the code easier to reason about and more robust.

[PATCH OLK-6.6] iio: adc: at91: call input_free_device() on allocated iio_dev
by Wupeng Ma 17 Feb '25

17 Feb '25

From: Joe Hattori <joe(a)pf.is.s.u-tokyo.ac.jp> stable inclusion from stable-v6.6.72 commit 09e067e3c83e0695d338e8a26916e3c2bc44be02 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBIQWA CVE: CVE-2024-57904 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit de6a73bad1743e9e81ea5a24c178c67429ff510b upstream. Current implementation of at91_ts_register() calls input_free_deivce() on st->ts_input, however, the err label can be reached before the allocated iio_dev is stored to st->ts_input. Thus call input_free_device() on input instead of st->ts_input.

[PATCH OLK-6.6] sched: sch_cake: add bounds checks to host bulk flow fairness counts
by Dong Chenchen 15 Feb '25

15 Feb '25

From: Toke Høiland-Jørgensen <toke(a)redhat.com> stable inclusion from stable-v6.6.72 commit 27202e2e8721c3b23831563c36ed5ac7818641ba category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBIQOT CVE: CVE-2025-21647 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 737d4d91d35b5f7fa5bb442651472277318b0bfd ] Even though we fixed a logic error in the commit cited below, syzbot still managed to trigger an underflow of the per-host bulk flow counters, leading to an out of bounds memory access. To avoid any such logic errors causing out of bounds memory accesses, this commit factors out all accesses to the per-host bulk flow counters to a series of helpers that perform bounds-checking before any increments and decrements. This also has the benefit of improving readability by moving the conditional checks for the flow mode into these helpers, instead of having them spread out throughout the code (which was the cause of the original logic error). As part of this change, the flow quantum calculation is consolidated into a helper function, which means that the dithering applied to the ost load scaling is now applied both in the DRR rotation and when a sparse flow's quantum is first initiated. The only user-visible effect of this is that the maximum packet size that can be sent while a flow stays sparse will now vary with +/- one byte in some cases.

[PATCH OLK-6.6] net/sched: netem: account for backlog updates from child qdisc
by Dong Chenchen 15 Feb '25

15 Feb '25

From: Martin Ottens <martin.ottens(a)fau.de> stable inclusion from stable-v6.6.67 commit 3824c5fad18eeb7abe0c4fc966f29959552dca3e category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBJCV9 CVE: CVE-2024-56770 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit f8d4bc455047cf3903cd6f85f49978987dbb3027 ] In general, 'qlen' of any classful qdisc should keep track of the number of packets that the qdisc itself and all of its children holds. In case of netem, 'qlen' only accounts for the packets in its internal tfifo. When netem is used with a child qdisc, the child qdisc can use 'qdisc_tree_reduce_backlog' to inform its parent, netem, about created or dropped SKBs. This function updates 'qlen' and the backlog statistics of netem, but netem does not account for changes made by a child qdisc. 'qlen' then indicates the wrong number of packets in the tfifo. If a child qdisc creates new SKBs during enqueue and informs its parent about this, netem's 'qlen' value is increased. When netem dequeues the newly created SKBs from the child, the 'qlen' in netem is not updated. If 'qlen' reaches the configured sch->limit, the enqueue function stops working, even though the tfifo is not full. Reproduce the bug: Ensure that the sender machine has GSO enabled. Configure netem as root qdisc and tbf as its child on the outgoing interface of the machine as follows: $ tc qdisc add dev <oif> root handle 1: netem delay 100ms limit 100 $ tc qdisc add dev <oif> parent 1:0 tbf rate 50Mbit burst 1542 latency 50ms Send bulk TCP traffic out via this interface, e.g., by running an iPerf3 client on the machine. Check the qdisc statistics: $ tc -s qdisc show dev <oif> Statistics after 10s of iPerf3 TCP test before the fix (note that netem's backlog > limit, netem stopped accepting packets): qdisc netem 1: root refcnt 2 limit 1000 delay 100ms Sent 2767766 bytes 1848 pkt (dropped 652, overlimits 0 requeues 0) backlog 4294528236b 1155p requeues 0 qdisc tbf 10: parent 1:1 rate 50Mbit burst 1537b lat 50ms Sent 2767766 bytes 1848 pkt (dropped 327, overlimits 7601 requeues 0) backlog 0b 0p requeues 0 Statistics after the fix: qdisc netem 1: root refcnt 2 limit 1000 delay 100ms Sent 37766372 bytes 24974 pkt (dropped 9, overlimits 0 requeues 0) backlog 0b 0p requeues 0 qdisc tbf 10: parent 1:1 rate 50Mbit burst 1537b lat 50ms Sent 37766372 bytes 24974 pkt (dropped 327, overlimits 96017 requeues 0) backlog 0b 0p requeues 0 tbf segments the GSO SKBs (tbf_segment) and updates the netem's 'qlen'. The interface fully stops transferring packets and "locks". In this case, the child qdisc and tfifo are empty, but 'qlen' indicates the tfifo is at its limit and no more packets are accepted. This patch adds a counter for the entries in the tfifo. Netem's 'qlen' is only decreased when a packet is returned by its dequeue function, and not during enqueuing into the child qdisc. External updates to 'qlen' are thus accounted for and only the behavior of the backlog statistics changes. As in other qdiscs, 'qlen' then keeps track of how many packets are held in netem and all of its children. As before, sch->limit remains as the maximum number of packets in the tfifo. The same applies to netem's backlog statistics.

[PATCH OLK-6.6] ipv6: Fix soft lockups in fib6_select_path under high next hop churn
by Dong Chenchen 15 Feb '25

15 Feb '25

From: Omid Ehtemam-Haghighi <omid.ehtemamhaghighi(a)menlosecurity.com> mainline inclusion from mainline-v6.13-rc1 commit d9ccb18f83ea2bb654289b6ecf014fd267cc988b category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBEDOT CVE: CVE-2024-56703 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Soft lockups have been observed on a cluster of Linux-based edge routers located in a highly dynamic environment. Using the `bird` service, these routers continuously update BGP-advertised routes due to frequently changing nexthop destinations, while also managing significant IPv6 traffic. The lockups occur during the traversal of the multipath circular linked-list in the `fib6_select_path` function, particularly while iterating through the siblings in the list. The issue typically arises when the nodes of the linked list are unexpectedly deleted concurrently on a different core—indicated by their 'next' and 'previous' elements pointing back to the node itself and their reference count dropping to zero. This results in an infinite loop, leading to a soft lockup that triggers a system panic via the watchdog timer. Apply RCU primitives in the problematic code sections to resolve the issue. Where necessary, update the references to fib6_siblings to annotate or use the RCU APIs. Include a test script that reproduces the issue. The script periodically updates the routing table while generating a heavy load of outgoing IPv6 traffic through multiple iperf3 clients. It consistently induces infinite soft lockups within a couple of minutes.

[PATCH OLK-6.6] net/mlx5e: Don't call cleanup on profile rollback failure
by Dong Chenchen 15 Feb '25

15 Feb '25

From: Cosmin Ratiu <cratiu(a)nvidia.com> mainline inclusion from mainline-v6.12-rc4 commit 4dbc1d1a9f39c3711ad2a40addca04d07d9ab5d0 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IB2SU8 CVE: CVE-2024-50146 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- When profile rollback fails in mlx5e_netdev_change_profile, the netdev profile var is left set to NULL. Avoid a crash when unloading the driver by not calling profile->cleanup in such a case. This was encountered while testing, with the original trigger that the wq rescuer thread creation got interrupted (presumably due to Ctrl+C-ing modprobe), which gets converted to ENOMEM (-12) by mlx5e_priv_init, the profile rollback also fails for the same reason (signal still active) so the profile is left as NULL, leading to a crash later in _mlx5e_remove.

[PATCH OLK-6.6] ethtool: fail closed if we can't get max channel used in indirection tables

From: Jakub Kicinski <kuba(a)kernel.org> mainline inclusion from mainline-v6.11-rc1 commit 2899d58462ba868287d6ff3acad3675e7adf934f category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAUATO CVE: CVE-2024-46834 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Commit 0d1b7d6c9274 ("bnxt: fix crashes when reducing ring count with active RSS contexts") proves that allowing indirection table to contain channels with out of bounds IDs may lead to crashes. Currently the max channel check in the core gets skipped if driver can't fetch the indirection table or when we can't allocate memory. Both of those conditions should be extremely rare but if they do happen we should try to be safe and fail the channel change.

[PATCH OLK-5.10] sched: sch_cake: add bounds checks to host bulk flow fairness counts
by Dong Chenchen 15 Feb '25

15 Feb '25

From: Toke Høiland-Jørgensen <toke(a)redhat.com> mainline inclusion from mainline-v6.13-rc7 commit 737d4d91d35b5f7fa5bb442651472277318b0bfd category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBIQOT CVE: CVE-2025-21647 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Even though we fixed a logic error in the commit cited below, syzbot still managed to trigger an underflow of the per-host bulk flow counters, leading to an out of bounds memory access. To avoid any such logic errors causing out of bounds memory accesses, this commit factors out all accesses to the per-host bulk flow counters to a series of helpers that perform bounds-checking before any increments and decrements. This also has the benefit of improving readability by moving the conditional checks for the flow mode into these helpers, instead of having them spread out throughout the code (which was the cause of the original logic error). As part of this change, the flow quantum calculation is consolidated into a helper function, which means that the dithering applied to the ost load scaling is now applied both in the DRR rotation and when a sparse flow's quantum is first initiated. The only user-visible effect of this is that the maximum packet size that can be sent while a flow stays sparse will now vary with +/- one byte in some cases. This should not make a noticeable difference in practice, and thus it's not worth complicating the code to preserve the old behaviour.

This assumption is bogus since it's valid to create egress qdiscs with major handle ffff: Budimir Markovic found that for qdiscs like DRR that maintain an active class list, it will cause a UAF with a dangling class pointer. In 066a3b5b2346, the concern was to avoid iterating over the ingress qdisc since its parent is itself. The proper fix is to stop when parent TC_H_ROOT is reached because the only way to retrieve ingress is when a hierarchy which does not contain a ffff: major handle call into qdisc_lookup with TC_H_MAJ(TC_H_ROOT). In the scenario where major ffff: is an egress qdisc in any of the tree levels, the updates will also propagate to TC_H_ROOT, which then the iteration must stop.

[PATCH OLK-5.10] ila: call nf_unregister_net_hooks() sooner

From: Eric Dumazet <edumazet(a)google.com> stable inclusion from stable-v5.10.226 commit 93ee345ba349922834e6a9d1dadabaedcc12dce6 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IARWHA CVE: CVE-2024-46782 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 031ae72825cef43e4650140b800ad58bf7a6a466 upstream. syzbot found an use-after-free Read in ila_nf_input [1] Issue here is that ila_xlat_exit_net() frees the rhashtable, then call nf_unregister_net_hooks(). It should be done in the reverse way, with a synchronize_rcu(). This is a good match for a pre_exit() method.

15 Feb '25

From: Adrian Huang <ahuang12(a)lenovo.com> mainline inclusion from mainline-v6.13-rc1 commit 9e9e085effe9b7e342138fde3cf8577d22509932 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBEAMT CVE: CVE-2024-56559 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… ------------------------------------------- When compiling kernel source 'make -j $(nproc)' with the up-and-running KASAN-enabled kernel on a 256-core machine, the following soft lockup is shown: watchdog: BUG: soft lockup - CPU#28 stuck for 22s!

The following ftrace log shows that the lockup CPU spends too much time iterating vmap_nodes and flushing TLB when purging vm_area structures. (Some info is trimmed). kworker: funcgraph_entry: | drain_vmap_area_work() { kworker: funcgraph_entry: | mutex_lock() { kworker: funcgraph_entry: 1.092 us | __cond_resched(); kworker: funcgraph_exit: 3.306 us | } ... ... kworker: funcgraph_entry: | flush_tlb_kernel_range() { ... ... kworker: funcgraph_exit: # 7533.649 us | } ... ... kworker: funcgraph_entry: 2.344 us | mutex_unlock(); kworker: funcgraph_exit: $ 23871554 us | } The drain_vmap_area_work() spends over 23 seconds. There are 2805 flush_tlb_kernel_range() calls in the ftrace log. * One is called in __purge_vmap_area_lazy(). * Others are called by purge_vmap_node->kasan_release_vmalloc. purge_vmap_node() iteratively releases kasan vmalloc allocations and flushes TLB for each vmap_area. - [Rough calculation] Each flush_tlb_kernel_range() runs about 7.5ms. -- 2804 * 7.5ms = 21.03 seconds. -- That's why a soft lock is triggered. 2. Extending the soft lockup time can work around the issue (For example, # echo 60 > /proc/sys/kernel/watchdog_thresh). This confirms the above-mentioned speculation: drain_vmap_area_work() spends too much time. If we combine all TLB flush operations of the KASAN shadow virtual address into one operation in the call path 'purge_vmap_node()->kasan_release_vmalloc()', the running time of drain_vmap_area_work() can be saved greatly. The idea is from the flush_tlb_kernel_range() call in __purge_vmap_area_lazy(). And, the soft lockup won't be triggered. Here is the test result based on 6.10: [6.10 wo/ the patch] 1. ftrace latency profiling (record a trace if the latency > 20s). echo 20000000 > /sys/kernel/debug/tracing/tracing_thresh echo drain_vmap_area_work > /sys/kernel/debug/tracing/set_graph_function echo function_graph > /sys/kernel/debug/tracing/current_tracer echo 1 > /sys/kernel/debug/tracing/tracing_on 2. Run `make -j $(nproc)` to compile the kernel source 3. Once the soft lockup is reproduced, check the ftrace log: cat /sys/kernel/debug/tracing/trace # tracer: function_graph # # CPU DURATION FUNCTION CALLS # | | | | | | | 76) $ 50412985 us | } /* __purge_vmap_area_lazy */ 76) $ 50412997 us | } /* drain_vmap_area_work */ 76) $ 29165911 us | } /* __purge_vmap_area_lazy */ 76) $ 29165926 us | } /* drain_vmap_area_work */ 91) $ 53629423 us | } /* __purge_vmap_area_lazy */ 91) $ 53629434 us | } /* drain_vmap_area_work */ 91) $ 28121014 us | } /* __purge_vmap_area_lazy */ 91) $ 28121026 us | } /* drain_vmap_area_work */ [6.10 w/ the patch] 1. Repeat step 1-2 in "[6.10 wo/ the patch]" 2. The soft lockup is not triggered and ftrace log is empty. cat /sys/kernel/debug/tracing/trace # tracer: function_graph # # CPU DURATION FUNCTION CALLS # | | | | | | | 3. Setting 'tracing_thresh' to 10/5 seconds does not get any ftrace log. 4. Setting 'tracing_thresh' to 1 second gets ftrace log. cat /sys/kernel/debug/tracing/trace # tracer: function_graph # # CPU DURATION FUNCTION CALLS # | | | | | | | 23) $ 1074942 us | } /* __purge_vmap_area_lazy */ 23) $ 1074950 us | } /* drain_vmap_area_work */ The worst execution time of drain_vmap_area_work() is about 1 second.

From: Junlin Li <make24(a)iscas.ac.cn> mainline inclusion from mainline-v6.12-rc5 commit 46d7ebfe6a75a454a5fa28604f0ef1491f9d8d14 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAYPJG CVE: CVE-2024-47697 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Ensure index in rtl2830_pid_filter does not exceed 31 to prevent out-of-bounds access. dev->filters is a 32-bit value, so set_bit and clear_bit functions should only operate on indices from 0 to 31. If index is 32, it will attempt to access a non-existent 33rd bit, leading to out-of-bounds access. Change the boundary check from index > 32 to index >= 32 to resolve this issue.

[PATCH OLK-6.6] fs/proc: fix softlockup in __read_vmcore (part 2)
by Li Huafei 13 Feb '25

13 Feb '25

From: Rik van Riel <riel(a)surriel.com> stable inclusion from stable-v6.6.74 commit a5a2ee8144c3897d37403a69118c3e3dc5713958 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBLWTG CVE: CVE-2025-21694 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit cbc5dde0a461240046e8a41c43d7c3b76d5db952 upstream. Since commit 5cbcb62dddf5 ("fs/proc: fix softlockup in __read_vmcore") the number of softlockups in __read_vmcore at kdump time have gone down, but they still happen sometimes. In a memory constrained environment like the kdump image, a softlockup is not just a harmless message, but it can interfere with things like RCU freeing memory, causing the crashdump to get stuck. The second loop in __read_vmcore has a lot more opportunities for natural sleep points, like scheduling out while waiting for a data write to happen, but apparently that is not always enough. Add a cond_resched() to the second loop in __read_vmcore to (hopefully) get rid of the softlockups.

[PATCH OLK-6.6] irqchip/gic-v3-its: Don't enable interrupts in its_irq_set_vcpu_affinity()
by Yuntao Liu 12 Feb '25

From: Tomas Krcka <krckatom(a)amazon.de> stable inclusion from stable-v6.6.74 commit 6c84ff2e788fce0099ee3e71a3ed258b1ca1a223 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBL2TI CVE: CVE-2024-57949 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 35cb2c6ce7da545f3b5cb1e6473ad7c3a6f08310 upstream. The following call-chain leads to enabling interrupts in a nested interrupt disabled section: irq_set_vcpu_affinity() irq_get_desc_lock() raw_spin_lock_irqsave() <--- Disable interrupts its_irq_set_vcpu_affinity() guard(raw_spinlock_irq) <--- Enables interrupts when leaving the guard() irq_put_desc_unlock() <--- Warns because interrupts are enabled This was broken in commit b97e8a2f7130, which replaced the original raw_spin_[un]lock() pair with guard(raw_spinlock_irq). Fix the issue by using guard(raw_spinlock).

[PATCH OLK-6.6] ALSA: caiaq: Use snd_card_free_when_closed() at disconnection
by Yu Kuai 11 Feb '25

11 Feb '25

From: Takashi Iwai <tiwai(a)suse.de> stable inclusion from stable-v6.6.64 commit 4507a8b9b30344c5ddd8219945f446d47e966a6d category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBEAFS CVE: CVE-2024-56531 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit b04dcbb7f7b1908806b7dc22671cdbe78ff2b82c ] The USB disconnect callback is supposed to be short and not too-long waiting. OTOH, the current code uses snd_card_free() at disconnection, but this waits for the close of all used fds, hence it can take long. It eventually blocks the upper layer USB ioctls, which may trigger a soft lockup. An easy workaround is to replace snd_card_free() with snd_card_free_when_closed(). This variant returns immediately while the release of resources is done asynchronously by the card device release at the last close. This patch also splits the code to the disconnect and the free phases; the former is called immediately at the USB disconnect callback while the latter is called from the card destructor.

[PATCH OLK-6.6] gpio: xilinx: Convert gpio_lock to raw spinlock
by Liu Chuang 11 Feb '25

11 Feb '25

From: Sean Anderson <sean.anderson(a)linux.dev> stable inclusion from stable-v6.6.74 commit b0111650ee596219bb5defa0ce1a1308e6e77ccf category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBL2TF CVE: CVE-2025-21684 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 9860370c2172704b6b4f0075a0c2a29fd84af96a upstream. irq_chip functions may be called in raw spinlock context. Therefore, we must also use a raw spinlock for our own internal locking. This fixes the following lockdep splat: [ 5.349336] ============================= [ 5.353349] [ BUG: Invalid wait context ] [ 5.357361] 6.13.0-rc5+ #69 Tainted: G W [ 5.363031] ----------------------------- [ 5.367045] kworker/u17:1/44 is trying to lock: [ 5.371587] ffffff88018b02c0 (&chip->gpio_lock){....}-{3:3}, at: xgpio_irq_unmask (drivers/gpio/gpio-xilinx.c:433 (discriminator 8)) [ 5.380079] other info that might help us debug this: [ 5.385138] context-{5:5} [ 5.387762] 5 locks held by kworker/u17:1/44: [ 5.392123] #0: ffffff8800014958 ((wq_completion)events_unbound){+.+.}-{0:0}, at: process_one_work (kernel/workqueue.c:3204) [ 5.402260] #1: ffffffc082fcbdd8 (deferred_probe_work){+.+.}-{0:0}, at: process_one_work (kernel/workqueue.c:3205) [ 5.411528] #2: ffffff880172c900 (&dev->mutex){....}-{4:4}, at: __device_attach (drivers/base/dd.c:1006) [ 5.419929] #3: ffffff88039c8268 (request_class#2){+.+.}-{4:4}, at: __setup_irq (kernel/irq/internals.h:156 kernel/irq/manage.c:1596) [ 5.428331] #4: ffffff88039c80c8 (lock_class#2){....}-{2:2}, at: __setup_irq (kernel/irq/manage.c:1614) [ 5.436472] stack backtrace: [ 5.439359] CPU: 2 UID: 0 PID: 44 Comm: kworker/u17:1 Tainted: G W 6.13.0-rc5+ #69 [ 5.448690] Tainted: [W]=WARN [ 5.451656] Hardware name: xlnx,zynqmp (DT) [ 5.455845] Workqueue: events_unbound deferred_probe_work_func [ 5.461699] Call trace: [ 5.464147] show_stack+0x18/0x24 C [ 5.467821] dump_stack_lvl (lib/dump_stack.c:123) [ 5.471501] dump_stack (lib/dump_stack.c:130) [ 5.474824] __lock_acquire (kernel/locking/lockdep.c:4828 kernel/locking/lockdep.c:4898 kernel/locking/lockdep.c:5176) [ 5.478758] lock_acquire (arch/arm64/include/asm/percpu.h:40 kernel/locking/lockdep.c:467 kernel/locking/lockdep.c:5851 kernel/locking/lockdep.c:5814) [ 5.482429] _raw_spin_lock_irqsave (include/linux/spinlock_api_smp.h:111 kernel/locking/spinlock.c:162) [ 5.486797] xgpio_irq_unmask (drivers/gpio/gpio-xilinx.c:433 (discriminator 8)) [ 5.490737] irq_enable (kernel/irq/internals.h:236 kernel/irq/chip.c:170 kernel/irq/chip.c:439 kernel/irq/chip.c:432 kernel/irq/chip.c:345) [ 5.494060] __irq_startup (kernel/irq/internals.h:241 kernel/irq/chip.c:180 kernel/irq/chip.c:250) [ 5.497645] irq_startup (kernel/irq/chip.c:270) [ 5.501143] __setup_irq (kernel/irq/manage.c:1807) [ 5.504728] request_threaded_irq (kernel/irq/manage.c:2208) Fixes: a32c7caea292 ("gpio: gpio-xilinx: Add interrupt support") Signed-off-by: Sean Anderson <sean.anderson(a)linux.dev> Cc: stable(a)vger.kernel.org Link: https://lore.kernel.org/r/20250110163354.2012654-1-sean.anderson@linux.dev Signed-off-by: Bartosz Golaszewski <bartosz.golaszewski(a)linaro.org> Signed-off-by: Greg Kroah-Hartman <gregkh(a)linuxfoundation.org> Signed-off-by: Liu Chuang <liuchuang40(a)huawei.com> --- drivers/gpio/gpio-xilinx.c | 32 ++++++++++++++++---------------- 1 file changed, 16 insertions(+), 16 deletions(-) diff --git a/drivers/gpio/gpio-xilinx.c b/drivers/gpio/gpio-xilinx.c index a16945e8319e..956ea2957833 100644 --- a/drivers/gpio/gpio-xilinx.c +++ b/drivers/gpio/gpio-xilinx.c @@ -66,7 +66,7 @@ struct xgpio_instance { DECLARE_BITMAP(state, 64);

[PATCH OLK-5.10] ALSA: seq: oss: Fix races at processing SysEx messages
by Gu Bowen 11 Feb '25

11 Feb '25

From: Takashi Iwai <tiwai(a)suse.de> stable inclusion from stable-v6.6.70 commit d2392b79d8af3714ea8878b71c66dc49d3110f44 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBID2T CVE: CVE-2024-57893 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 0179488ca992d79908b8e26b9213f1554fc5bacc upstream. OSS sequencer handles the SysEx messages split in 6 bytes packets, and ALSA sequencer OSS layer tries to combine those. It stores the data in the internal buffer and this access is racy as of now, which may lead to the out-of-bounds access. As a temporary band-aid fix, introduce a mutex for serializing the process of the SysEx message packets.

[PATCH OLK-5.10] RDMA/hns: Fix free_mr_qp not assigning qp->device in error flow
by Chengchang Tang 10 Feb '25

10 Feb '25

From: Junxian Huang <huangjunxian6(a)hisilicon.com> driver inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBLA1C --------------------------------------------------------------- For HIP08, the driver creates 8 free_mr_qp in free_mr_alloc_res(), and then assigns qp->device for them in free_mr_modify_rsv_qp().

Since the NAPI_STATE_SCHED bit has been cleared, napi_schedule_rps() can be retriggered in enqueue_to_backlog(), causing this issue. Making the napi's weight always non-zero solves this problem. Triggering this issue requires system-wide admin (setting is not namespaced).

[PATCH OLK-5.10] pinmux: Use sequential access to access desc->pinmux data
by Zhang Kunbo 08 Feb '25

08 Feb '25

From: Mukesh Ojha <quic_mojha(a)quicinc.com> stable inclusion from stable-v6.6.66 commit 2da32aed4a97ca1d70fb8b77926f72f30ce5fb4b category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBIFR8 CVE: CVE-2024-47141 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 5a3e85c3c397c781393ea5fb2f45b1f60f8a4e6e ] When two client of the same gpio call pinctrl_select_state() for the same functionality, we are seeing NULL pointer issue while accessing desc->mux_owner. Let's say two processes A, B executing in pin_request() for the same pin and process A updates the desc->mux_usecount but not yet updated the desc->mux_owner while process B see the desc->mux_usecount which got updated by A path and further executes strcmp and while accessing desc->mux_owner it crashes with NULL pointer. Serialize the access to mux related setting with a mutex lock. cpu0 (process A) cpu1(process B) pinctrl_select_state() { pinctrl_select_state() { pin_request() { pin_request() { ... .... } else { desc->mux_usecount++; desc->mux_usecount && strcmp(desc->mux_owner, owner)) { if (desc->mux_usecount > 1) return 0; desc->mux_owner = owner; } } Signed-off-by: Mukesh Ojha <quic_mojha(a)quicinc.com> Link: https://lore.kernel.org/20241014192930.1539673-1-quic_mojha@quicinc.com Signed-off-by: Linus Walleij <linus.walleij(a)linaro.org> Signed-off-by: Sasha Levin <sashal(a)kernel.org> Conflicts: drivers/pinctrl/pinmux.c [ Scope-based resource management is not merged yet (54da6a092431), so we lock the data-race region by hand ] Signed-off-by: Zhang Kunbo <zhangkunbo(a)huawei.com> --- drivers/pinctrl/core.c | 3 +++ drivers/pinctrl/core.h | 1 + drivers/pinctrl/pinmux.c | 49 ++++++++++++++++++++++++++++++++++------ 3 files changed, 46 insertions(+), 7 deletions(-) diff --git a/drivers/pinctrl/core.c b/drivers/pinctrl/core.c index b7a6bab4ac01..118c4975c777 100644 --- a/drivers/pinctrl/core.c +++ b/drivers/pinctrl/core.c @@ -220,6 +220,9 @@ static int pinctrl_register_one_pin(struct pinctrl_dev *pctldev, /* Set owner */ pindesc->pctldev = pctldev;

[PATCH OLK-5.10] pinmux: Use sequential access to access desc->pinmux data

From: Mukesh Ojha <quic_mojha(a)quicinc.com> stable inclusion from stable-v6.6.66 commit 2da32aed4a97ca1d70fb8b77926f72f30ce5fb4b category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBIFR8 CVE: CVE-2024-47141 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 5a3e85c3c397c781393ea5fb2f45b1f60f8a4e6e ] When two client of the same gpio call pinctrl_select_state() for the same functionality, we are seeing NULL pointer issue while accessing desc->mux_owner. Let's say two processes A, B executing in pin_request() for the same pin and process A updates the desc->mux_usecount but not yet updated the desc->mux_owner while process B see the desc->mux_usecount which got updated by A path and further executes strcmp and while accessing desc->mux_owner it crashes with NULL pointer. Serialize the access to mux related setting with a mutex lock. cpu0 (process A) cpu1(process B) pinctrl_select_state() { pinctrl_select_state() { pin_request() { pin_request() { ... .... } else { desc->mux_usecount++;

[PATCH OLK-6.6] wifi: mac80211: fix mbss changed flags corruption on 32 bit systems
by Wang Wensheng 07 Feb '25

07 Feb '25

From: Issam Hamdi <ih(a)simonwunderlich.de> stable inclusion from stable-v6.6.70 commit 86772872f9f5097cd03d0e1c6813238bd38c250b category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBID2X CVE: CVE-2024-57899 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 49dba1ded8dd5a6a12748631403240b2ab245c34 ] On 32-bit systems, the size of an unsigned long is 4 bytes, while a u64 is 8 bytes. Therefore, when using or_each_set_bit(bit, &bits, sizeof(changed) * BITS_PER_BYTE), the code is incorrectly searching for a bit in a 32-bit variable that is expected to be 64 bits in size, leading to incorrect bit finding. Solution: Ensure that the size of the bits variable is correctly adjusted for each architecture.

[PATCH OLK-6.6] gve: guard XDP xmit NDO on existence of xdp queues
by Wang Liang 07 Feb '25

07 Feb '25

From: Joshua Washington <joshwash(a)google.com> stable inclusion from stable-v6.6.70 commit cbe9eb2c39d09f3c8574febcfa39d8c09d0c7cb5 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBJ6O9 CVE: CVE-2024-57932 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit ff7c2dea9dd1a436fc79d6273adffdcc4a7ffea3 upstream. In GVE, dedicated XDP queues only exist when an XDP program is installed and the interface is up. As such, the NDO XDP XMIT callback should return early if either of these conditions are false. In the case of no loaded XDP program, priv->num_xdp_queues=0 which can cause a divide-by-zero error, and in the case of interface down, num_xdp_queues remains untouched to persist XDP queue count for the next interface up, but the TX pointer itself would be NULL. The XDP xmit callback also needs to synchronize with a device transitioning from open to close. This synchronization will happen via the GVE_PRIV_FLAGS_NAPI_ENABLED bit along with a synchronize_net() call, which waits for any RCU critical sections at call-time to complete.

[PATCH OLK-6.6] gve: guard XSK operations on the existence of queues
by Wang Liang 07 Feb '25

07 Feb '25

From: Joshua Washington <joshwash(a)google.com> stable inclusion from stable-v6.6.70 commit 771d66f2bd8c4dba1286a9163ab982cecd825718 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBJ6P5 CVE: CVE-2024-57933 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 40338d7987d810fcaa95c500b1068a52b08eec9b upstream. This patch predicates the enabling and disabling of XSK pools on the existence of queues. As it stands, if the interface is down, disabling or enabling XSK pools would result in a crash, as the RX queue pointer would be NULL. XSK pool registration will occur as part of the next interface up. Similarly, xsk_wakeup needs be guarded against queues disappearing while the function is executing, so a check against the GVE_PRIV_FLAGS_NAPI_ENABLED flag is added to synchronize with the disabling of the bit and the synchronize_net() in gve_turndown.

The root cause is a buggy MPTCP option len computation in some circumstances: the ADD_ADDR option should be mutually exclusive with DSS since the blamed commit. Still, mptcp_established_options_add_addr() tries to set the relevant info in mptcp_out_options, if the remaining space is large enough even when DSS is present. Since the ADD_ADDR infos and the DSS share the same union fields, adding first corrupts the latter. In the worst-case scenario, such corruption increases the DSS binary layout, exceeding the computed length and possibly overwriting the skb shared info. Address the issue by enforcing mutual exclusion in mptcp_established_options_add_addr(), too.

[PATCH OLK-5.10] pinmux: Use sequential access to access desc->pinmux data
by Zhang Kunbo 06 Feb '25

06 Feb '25

From: Mukesh Ojha <quic_mojha(a)quicinc.com> stable inclusion from stable-v6.6.66 commit 2da32aed4a97ca1d70fb8b77926f72f30ce5fb4b category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBIFR8 CVE: CVE-2024-47141 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 5a3e85c3c397c781393ea5fb2f45b1f60f8a4e6e ] When two client of the same gpio call pinctrl_select_state() for the same functionality, we are seeing NULL pointer issue while accessing desc->mux_owner. Let's say two processes A, B executing in pin_request() for the same pin and process A updates the desc->mux_usecount but not yet updated the desc->mux_owner while process B see the desc->mux_usecount which got updated by A path and further executes strcmp and while accessing desc->mux_owner it crashes with NULL pointer. Serialize the access to mux related setting with a mutex lock. cpu0 (process A) cpu1(process B) pinctrl_select_state() { pinctrl_select_state() { pin_request() { pin_request() { ... .... } else { desc->mux_usecount++;

From: Issam Hamdi <ih(a)simonwunderlich.de> stable inclusion from stable-v6.6.70 commit 86772872f9f5097cd03d0e1c6813238bd38c250b category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBID2X CVE: CVE-2024-57899 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 49dba1ded8dd5a6a12748631403240b2ab245c34 ] On 32-bit systems, the size of an unsigned long is 4 bytes, while a u64 is 8 bytes. Therefore, when using or_each_set_bit(bit, &bits, sizeof(changed) * BITS_PER_BYTE), the code is incorrectly searching for a bit in a 32-bit variable that is expected to be 64 bits in size, leading to incorrect bit finding. Solution: Ensure that the size of the bits variable is correctly adjusted for each architecture.

[PATCH OLK-6.6] iio: adc: at91: call input_free_device() on allocated iio_dev
by Wupeng Ma 06 Feb '25

06 Feb '25

From: Joe Hattori <joe(a)pf.is.s.u-tokyo.ac.jp> stable inclusion from stable-v6.6.72 commit 09e067e3c83e0695d338e8a26916e3c2bc44be02 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBIQWA CVE: CVE-2024-57904 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit de6a73bad1743e9e81ea5a24c178c67429ff510b upstream. Current implementation of at91_ts_register() calls input_free_deivce() on st->ts_input, however, the err label can be reached before the allocated iio_dev is stored to st->ts_input. Thus call input_free_device() on input instead of st->ts_input.
