[PATCH 1/5] usb: gadget: lpc32xx_udc: fix clock imbalance in error path

by Johan Hovold

A recent change fixing a device reference leak introduced a clock imbalance by reusing an error path so that the clock may be disabled before having been enabled. Note that the clock framework allows for passing in NULL clocks so there is no risk for a NULL pointer dereference. Also drop the bogus I2C client NULL check added by the offending commit as the pointer has already been verified to be non-NULL.

Fix this by moving the system sleep suspend/resume callbacks to the NOIRQ phase, ensuring the adapter is fully quiesced after late suspend and properly resumed before the early resume phase. To support NOIRQ resume, the hardware initialization path must not invoke runtime PM APIs. Split the init code so that the low-level hardware setup can be executed without pm_runtime_get/put(). This avoids violating the constraint introduced by commit 1e2ef05bb8cf ("PM: Limit race conditions between runtime PM and system sleep (v2)"), which forbids runtime PM calls during early resume.

[PATCH] rust: task: restrict Task::group_leader() to current

by Alice Ryhl

The Task::group_leader() method currently allows you to access the group_leader() of any task, for example one you hold a refcount to. But this is not safe in general since the group leader could change when a task exits. See for example commit a15f37a40145c ("kernel/sys.c: fix the racy usage of task_lock(tsk->group_leader) in sys_prlimit64() paths"). All existing users of Task::group_leader() call this method on current, which is guaranteed running, so there's not an actual issue in Rust code today. But to prevent code in the future from making this mistake, restrict Task::group_leader() so that it can only be called on current. There are some other cases where accessing task->group_leader is okay. For example it can be safe if you hold tasklist_lock or rcu_read_lock(). However, only supporting current->group_leader is sufficient for all in-tree Rust users of group_leader right now. Safe Rust functionality for accessing it under rcu or while holding tasklist_lock may be added in the future if required by any future Rust module.

[PATCH] Revert "clk: qcom: cpu-8996: simplify the cpu_clk_notifier_cb"

by Christopher Obbard

This reverts commit b3b274bc9d3d7307308aeaf75f70731765ac999a. On the DragonBoard 820c (which uses APQ8096/MSM8996) this change causes the CPUs to downclock to roughly half speed under sustained load. The regression is visible both during boot and when running CPU stress workloads such as stress-ng: the CPUs initially ramp up to the expected frequency, then drop to a lower OPP even though the system is clearly CPU-bound. Bisecting points to this commit and reverting it restores the expected behaviour on the DragonBoard 820c - the CPUs track the cpufreq policy and run at full performance under load. The exact interaction with the ACD is not yet fully understood and we would like to keep ACD in use to avoid possible SoC reliability issues. Until we have a better fix that preserves ACD while avoiding this performance regression, revert the bisected patch to restore the previous behaviour. Fixes: b3b274bc9d3d ("clk: qcom: cpu-8996: simplify the cpu_clk_notifier_cb") Cc: stable(a)vger.kernel.org # v6.3+ Link: https://lore.kernel.org/linux-arm-msm/20230113120544.59320-8-dmitry.baryshk… Cc: Dmitry Baryshkov <dmitry.baryshkov(a)oss.qualcomm.com> Signed-off-by: Christopher Obbard <christopher.obbard(a)linaro.org> --- Hi all, This series contains a single revert for a regression affecting the APQ8096/MSM8996 (DragonBoard 820c). The commit being reverted, b3b274bc9d3d ("clk: qcom: cpu-8996: simplify the cpu_clk_notifier_cb"), introduces a significant performance issue where the CPUs downclock to ~50% of their expected frequency under sustained load. The problem is reproducible both at boot and when running CPU-bound workloads such as stress-ng. Bisecting the issue pointed directly to this commit and reverting it restores correct cpufreq behaviour. The root cause appears to be related to the interaction between the simplified notifier callback and ACD (Adaptive Clock Distribution). Since we would prefer to keep ACD enabled for SoC reliability reasons, a revert is the safest option until a proper fix is identified. Full details are included in the commit message. Feedback & suggestions welcome. Cheers!
