2023-10-25hwmon: (nct6775) Fix incorrect variable reuse in fan_div calculationZev Weiss
In the regmap conversion in commit 4ef2774511dc ("hwmon: (nct6775) Convert register access to regmap API") I reused the 'reg' variable for all three register reads in the fan speed calculation loop in nct6775_update_device(), but failed to notice that the value from the first one (data->REG_FAN[i]) is actually used in the call to nct6775_select_fan_div() at the end of the loop body. Since that patch the register value passed to nct6775_select_fan_div() has been (conditionally) incorrectly clobbered with the value of a different register than intended, which has in at least some cases resulted in fan speeds being adjusted down to zero. Fix this by using dedicated temporaries for the two intermediate register reads instead of 'reg'.

2023-10-25irqchip/gic-v3-its: Don't override quirk settings with default valuesMarc Zyngier
When splitting the allocation of the ITS node from its configuration, some of the default settings were kept in the latter instead of being moved to the former. This has the side effect of negating some of the quirk detections that have happened in between, amongst which the dreaded Synquacer hack (that also affect Dominic's TI platform). Move the initialisation of these fields early, so that they can again be overriden by the Synquacer quirk.

2023-10-25Merge branch 'mptcp-features-and-fixes-for-v6-7'Jakub Kicinski
Mat Martineau says: ==================== mptcp: Features and fixes for v6.7 Patch 1 adds a configurable timeout for the MPTCP connection when all subflows are closed, to support break-before-make use cases. Patch 2 is a fix for a 1-byte error in rx data counters with MPTCP fastopen connections. Patch 3 is a minor code cleanup. Patches 4 & 5 add handling of rcvlowat for MPTCP sockets, with a prerequisite patch to use a common scaling ratio between TCP and MPTCP. Patch 6 improves efficiency of memory copying in MPTCP transmit code. Patch 7 refactors syncing of socket options from the MPTCP socket to its subflows. Patches 8 & 9 help the MPTCP packet scheduler perform well by changing the handling of notsent_lowat in subflows and how available buffer space is calculated for MPTCP-level sends. ==================== Link: https://lore.kernel.org/r/20231023-send-net-next-20231023-2-v1-0-9dc60939d371@kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2023-10-25mptcp: refactor sndbuf auto-tuningPaolo Abeni
The MPTCP protocol account for the data enqueued on all the subflows to the main socket send buffer, while the send buffer auto-tuning algorithm set the main socket send buffer size as the max size among the subflows. That causes bad performances when at least one subflow is sndbuf limited, e.g. due to very high latency, as the MPTCP scheduler can't even fill such buffer. Change the send-buffer auto-tuning algorithm to compute the main socket send buffer size as the sum of all the subflows buffer size.

2023-10-25mptcp: ignore notsent_lowat setting at the subflow levelPaolo Abeni
Any latency related tuning taking action at the subflow level does not really affect the user-space, as only the main MPTCP socket is relevant. Anyway any limiting setting may foul the MPTCP scheduler, not being able to fully use the subflow-level cwin, leading to very poor b/w usage. Enforce notsent_lowat to be a no-op on every subflow. Note that TCP_NOTSENT_LOWAT is currently not supported, and properly dealing with that will require more invasive changes.

2023-10-25mptcp: use copy_from_iter helpers on transmitPaolo Abeni
The perf traces show an high cost for the MPTCP transmit path memcpy. It turn out that the helper currently in use carries quite a bit of unneeded overhead, e.g. to map/unmap the memory pages. Moving to the 'copy_from_iter' variant removes such overhead and additionally gains the no-cache support.

2023-10-25mptcp: give rcvlowat some lovePaolo Abeni
The MPTCP protocol allow setting sk_rcvlowat, but the value there is currently ignored. Additionally, the default subflows sk_rcvlowat basically disables per subflow delayed ack: the MPTCP protocol move the incoming data from the subflows into the msk socket as soon as the TCP stacks invokes the subflow data_ready callback. Later, when __tcp_ack_snd_check() takes action, the subflow-level copied_seq matches rcv_nxt, and that mandate for an immediate ack. Let the mptcp receive path be aware of such threshold, explicitly tracking the amount of data available to be ready and checking vs sk_rcvlowat in mptcp_poll() and before waking-up readers. Additionally implement the set_rcvlowat() callback, to properly handle the rcvbuf auto-tuning on sk_rcvlowat changes. Finally to properly handle delayed ack, force the subflow level threshold to 0 and instead explicitly ask for an immediate ack when the msk level th is not reached.

2023-10-25genirq/matrix: Exclude managed interrupts in irq_matrix_allocated()Chen Yu
When a CPU is about to be offlined, x86 validates that all active interrupts which are targeted to this CPU can be migrated to the remaining online CPUs. If not, the offline operation is aborted. The validation uses irq_matrix_allocated() to retrieve the number of vectors which are allocated on the outgoing CPU. The returned number of allocated vectors includes also vectors which are associated to managed interrupts. That's overaccounting because managed interrupts are: - not migrated when the affinity mask of the interrupt targets only the outgoing CPU - migrated to another CPU, but in that case the vector is already pre-allocated on the potential target CPUs and must not be taken into account. As a consequence the check whether the remaining online CPUs have enough capacity for migrating the allocated vectors from the outgoing CPU might fail incorrectly. Let irq_matrix_allocated() return only the number of allocated non-managed interrupts to make this validation check correct.

When allocating a new pool at runtime, reduce the number of slabs so that the allocation order is at most MAX_ORDER. This avoids a kernel warning in __alloc_pages(). The warning is relatively benign, because the pool size is subsequently reduced when allocation fails, but it is silly to start with a request that is known to fail, especially since this is the default behavior if the kernel is built with CONFIG_SWIOTLB_DYNAMIC=y and booted without any swiotlb= parameter.

2023-10-25io_uring/rw: disable IOCB_DIO_CALLER_COMPJens Axboe
If an application does O_DIRECT writes with io_uring and the file system supports IOCB_DIO_CALLER_COMP, then completions of the dio write side is done from the task_work that will post the completion event for said write as well. Whenever a dio write is done against a file, the inode i_dio_count is elevated. This enables other callers to use inode_dio_wait() to wait for previous writes to complete. If we defer the full dio completion to task_work, we are dependent on that task_work being run before the inode i_dio_count can be decremented. If the same task that issues io_uring dio writes with IOCB_DIO_CALLER_COMP performs a synchronous system call that calls inode_dio_wait(), then we can deadlock as we're blocked sleeping on the event to become true, but not processing the completions that will result in the inode i_dio_count being decremented. Until we can guarantee that this is the case, then disable the deferred caller completions.

2023-10-25drm/i915/pmu: Check if pmu is closed before stopping eventUmesh Nerlige Ramappa
When the driver unbinds, pmu is unregistered and i915->uabi_engines is set to RB_ROOT. Due to this, when i915 PMU tries to stop the engine events, it issues a warn_on because engine lookup fails. All perf hooks are taking care of this using a pmu->closed flag that is set when PMU unregisters. The stop event seems to have been left out. Check for pmu->closed in pmu_event_stop as well.

2023-10-25drm/i915/mcr: Hold GT forcewake during steering operationsMatt Roper
The steering control and semaphore registers are inside an "always on" power domain with respect to RC6. However there are some issues if higher-level platform sleep states are entering/exiting at the same time these registers are accessed. Grabbing GT forcewake and holding it over the entire lock/steer/unlock cycle ensures that those sleep states have been fully exited before we access these registers. This is expected to become a formally documented/numbered workaround soon. Note that this patch alone isn't expected to have an immediately noticeable impact on MCR (mis)behavior; an upcoming pcode firmware update will also be necessary to provide the other half of this workaround. v2: - Move the forcewake inside the Xe_LPG-specific IP version check. This should only be necessary on platforms that have a steering semaphore.

2023-10-25wifi: ath12k: Introduce and use ath12k_sta_to_arsta()Jeff Johnson
Currently, the logic to return an ath12k_sta pointer, given a ieee80211_sta pointer, uses typecasting throughout the driver. In general, conversion functions are preferable to typecasting since using a conversion function allows the compiler to validate the types of both the input and output parameters. ath12k already defines a conversion function ath12k_vif_to_arvif() for a similar conversion. So introduce ath12k_sta_to_arsta() for this use case, and convert all of the existing typecasting to use this function.
