From: Shubham Panwar <shubiisp8(a)gmail.com> stable inclusion from stable-v4.19.323 commit 437885ab7c980a5ef0badcb4d7a5f36a20fd4bf5 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBBN6V Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… ------------------------------------------------------------- commit 8fa73ee44daefc884c53a25158c25a4107eb5a94 upstream. Add a DMI quirk for Samsung Galaxy Book2 to fix an initial lid state detection issue. The _LID device incorrectly returns the lid status as "closed" during boot, causing the system to enter a suspend loop right after booting. The quirk ensures that the correct lid state is reported initially, preventing the system from immediately suspending after startup. It only addresses the initial lid state detection and ensures proper system behavior upon boot.

[PATCH openEuler-1.0-LTS] x86/apic: Always explicitly disarm TSC-deadline timer
by Heyuan Wang 23 Dec '24

23 Dec '24

From: Zhang Rui <rui.zhang(a)intel.com> stable inclusion from stable-v4.19.323 commit e75562346cac53c7e933373a004b1829e861123a category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBBN6V Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… ------------------------------------------------------------- commit ffd95846c6ec6cf1f93da411ea10d504036cab42 upstream. New processors have become pickier about the local APIC timer state before entering low power modes. These low power modes are used (for example) when you close your laptop lid and suspend. If you put your laptop in a bag and it is not in this low power mode, it is likely to get quite toasty while it quickly sucks the battery dry. The problem boils down to some CPUs' inability to power down until the CPU recognizes that the local APIC timer is shut down. The current kernel code works in one-shot and periodic modes but does not work for deadline mode. Deadline mode has been the supported and preferred mode on Intel CPUs for over a decade and uses an MSR to drive the timer instead of an APIC register. Disable the TSC Deadline timer in lapic_timer_shutdown() by writing to MSR_IA32_TSC_DEADLINE when in TSC-deadline mode. Also avoid writing to the initial-count register (APIC_TMICT) which is ignored in TSC-deadline mode. Note: The APIC_LVTT|=APIC_LVT_MASKED operation should theoretically be enough to tell the hardware that the timer will not fire in any of the timer modes. But mitigating AMD erratum 411[1] also requires clearing out APIC_TMICT. Solely setting APIC_LVT_MASKED is also ineffective in practice on Intel Lunar Lake systems, which is the motivation for this change. 1. 411 Processor May Exit Message-Triggered C1E State Without an Interrupt if Local APIC Timer Reaches Zero - https://www.amd.com/content/dam/amd/en/documents/archived-tech-docs/revisio… Fixes: 279f1461432c ("x86: apic: Use tsc deadline for oneshot when available") Suggested-by: Dave Hansen <dave.hansen(a)intel.com> Signed-off-by: Zhang Rui <rui.zhang(a)intel.com> Signed-off-by: Dave Hansen <dave.hansen(a)linux.intel.com> Reviewed-by: Rafael J.

[PATCH openEuler-1.0-LTS] io_uring/io-wq: Use set_bit() and test_bit() at worker->flags
by Yifan Qiao 23 Dec '24

23 Dec '24

From: Breno Leitao <leitao(a)debian.org> mainline inclusion from mainline-v6.10-rc1 commit 8a565304927fbd28c9f028c492b5c1714002cbab category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IACR2Y CVE: CVE-2024-39508 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Utilize set_bit() and test_bit() on worker->flags within io_uring/io-wq to address potential data races. The structure io_worker->flags may be accessed through various data paths, leading to concurrency issues. When KCSAN is enabled, it reveals data races occurring in io_worker_handle_work and io_wq_activate_free_worker functions. BUG: KCSAN: data-race in io_worker_handle_work / io_wq_activate_free_worker write to 0xffff8885c4246404 of 4 bytes by task 49071 on cpu 28: io_worker_handle_work (io_uring/io-wq.c:434 io_uring/io-wq.c:569) io_wq_worker (io_uring/io-wq.c:?) <snip> read to 0xffff8885c4246404 of 4 bytes by task 49024 on cpu 5: io_wq_activate_free_worker (io_uring/io-wq.c:? io_uring/io-wq.c:285) io_wq_enqueue (io_uring/io-wq.c:947) io_queue_iowq (io_uring/io_uring.c:524) io_req_task_submit (io_uring/io_uring.c:1511) io_handle_tw_list (io_uring/io_uring.c:1198) <snip> Line numbers against commit 18daea77cca6 ("Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm"). These races involve writes and reads to the same memory location by different tasks running on different CPUs. To mitigate this, refactor the code to use atomic operations such as set_bit(), test_bit(), and clear_bit() instead of basic "and" and "or" operations. This ensures thread-safe manipulation of worker flags. Also, move `create_index` to avoid holes in the structure.
