2025-07-22genirq: Prevent migration live lock in handle_edge_irq()Thomas Gleixner
Yicon reported and Liangyan debugged a live lock in handle_edge_irq() related to interrupt migration. If the interrupt affinity is moved to a new target CPU and the interrupt is currently handled on the previous target CPU for edge type interrupts the handler might get stuck on the previous target: CPU 0 (previous target) CPU 1 (new target) handle_edge_irq() repeat: handle_event() handle_edge_irq() if (INPROGESS) { set(PENDING); mask(); return; } if (PENDING) { clear(PENDING); unmask(); goto repeat; } The migration in software never completes and CPU0 continues to handle the pending events forever. This happens when the device raises interrupts with a high rate and always before handle_event() completes and before the CPU0 handler can clear INPROGRESS so that CPU1 sets the PENDING flag over and over. This has been observed in virtual machines. Prevent this by checking whether the CPU which observes the INPROGRESS flag is the new affinity target. If that's the case, do not set the PENDING flag and wait for the INPROGRESS flag to be cleared instead, so that the new interrupt is handled on the new target CPU and the previous CPU is released from the action. This is restricted to the edge type handler and only utilized on systems, which use single CPU targets for interrupt affinity.

2025-07-22timekeeping: Zero initialize system_counterval when querying time from phc ↵Markus Blöchl
drivers Most drivers only populate the fields cycles and cs_id of system_counterval in their get_time_fn() callback for get_device_system_crosststamp(), unless they explicitly provide nanosecond values. When the use_nsecs field was added to struct system_counterval, most drivers did not care. Clock sources other than CSID_GENERIC could then get converted in convert_base_to_cs() based on an uninitialized use_nsecs field, which usually results in -EINVAL during the following range check. Pass in a fully zero initialized system_counterval_t to cure that.

2025-07-22Revert "drm/nouveau: check ioctl command codes better"Arnd Bergmann
My previous patch ended up causing a regression for the DRM_IOCTL_NOUVEAU_NVIF ioctl. The intention of my patch was to only pass ioctl commands that have the correct dir/type/nr bits into the nouveau_abi16_ioctl() function. This turned out to be too strict, as userspace does use at least write-only and write-read direction settings. Checking for both of these still did not fix the issue, so the best we can do for the 6.16 release is to revert back to what we've had since linux-3.16. This version is still fragile, but at least it is known to work with existing userspace. Fixing this properly requires a better understanding of what commands are being passed from userspace in practice, and how that relies on the undocumented (miss)behavior in nouveau_drm_ioctl().

can_priv::do_set_mode Andrei Lalaev reported a NULL pointer deref when a CAN device is restarted from Bus Off and the driver does not implement the struct can_priv::do_set_mode callback. There are 2 code path that call struct can_priv::do_set_mode: - directly by a manual restart from the user space, via can_changelink() - delayed automatic restart after bus off (deactivated by default) To prevent the NULL pointer deference, refuse a manual restart or configure the automatic restart delay in can_changelink() and report the error via extack to user space. As an additional safety measure let can_restart() return an error if can_priv::do_set_mode is not set instead of dereferencing it unchecked.

2025-07-22cpufreq: CPPC: Mark driver with NEED_UPDATE_LIMITS flagPrashant Malani
AMU counters on certain CPPC-based platforms tend to yield inaccurate delivered performance measurements on systems that are idle/mostly idle. This results in an inaccurate frequency being stored by cpufreq in its policy structure when the CPU is brought online. [1] Consequently, if the userspace governor tries to set the frequency to a new value, there is a possibility that it would be the erroneous value stored earlier. In such a scenario, cpufreq would assume that the requested frequency has already been set and return early, resulting in the correct/new frequency request never making it to the hardware. Since the operating frequency is liable to this sort of inconsistency, mark the CPPC driver with CPUFREQ_NEED_UPDATE_LIMITS so that it is always invoked when a target frequency update is requested.

qfq_delete_class might_sleep could be trigger in the atomic context in qfq_delete_class. qfq_destroy_class was moved into atomic context locked by sch_tree_lock to avoid a race condition bug on qfq_aggregate. However, might_sleep could be triggered by qfq_destroy_class, which introduced sleeping in atomic context (path: qfq_destroy_class->qdisc_put->__qdisc_destroy->lockdep_unregister_key ->might_sleep). Considering the race is on the qfq_aggregate objects, keeping qfq_rm_from_agg in the lock but moving the left part out can solve this issue.
