[PATCH OLK-5.10 00/10] Implementation of the uncore frequency modulation feature
by Xiangwei Li 17 Feb '25

17 Feb '25

Devfreq is a general DVFS framework for non-CPU devices in the kernel. It is generally used for bus devices. Implementation of uncore dynamic frequency modulation based on this framework. Jie Zhan (1): PM / devfreq: Add HiSilicon uncore frequency scaling driver Xiangwei Li (9): PM / devfreq: Adjust default HiSilicon uncore devfreq polling interval and workqueue PM / devfreq: event: Add devfreq_event_get_edev_by_dev interface PM / devfreq: event: Supplement the name content of the event in devfreq-event PM / devfreq: Add related-package parameter in HiSilicon uncore devfreq PM / devfreq: Add associated events configuration in HiSilicon uncore frequency PM / devfreq: event: Add L3C event for HiSilicon uncore devfreq PM / devfreq: Add until governor PM / devfreq: Add bandwidth verification mechanism PM / devfreq: event: Add DDRC event for HiSilicon uncore devfreq drivers/devfreq/Kconfig | 12 + drivers/devfreq/Makefile | 2 + drivers/devfreq/devfreq-event.c | 34 +- drivers/devfreq/event/Kconfig | 7 + drivers/devfreq/event/Makefile | 2 + drivers/devfreq/event/hisi-uncore-ddrc.c | 167 ++++++ drivers/devfreq/event/hisi-uncore-l3c.c | 166 ++++++ drivers/devfreq/event/hisi-uncore.c | 249 +++++++++ drivers/devfreq/event/hisi-uncore.h | 88 +++ drivers/devfreq/governor_util.c | 124 +++++ drivers/devfreq/hisi_uncore_freq.c | 681 +++++++++++++++++++++++ include/linux/devfreq-event.h | 8 + include/linux/devfreq.h | 15 + 13 files changed, 1554 insertions(+), 1 deletion(-) create mode 100644 drivers/devfreq/event/hisi-uncore-ddrc.c create mode 100644 drivers/devfreq/event/hisi-uncore-l3c.c create mode 100644 drivers/devfreq/event/hisi-uncore.c create mode 100644 drivers/devfreq/event/hisi-uncore.h create mode 100644 drivers/devfreq/governor_util.c create mode 100644 drivers/devfreq/hisi_uncore_freq.c -- 2.25.1

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.
