The user space calls mmap() to map VAS window paste address and the kernel returns the complete mapped page for each window. So return -EINVAL if non-zero is passed for offset parameter to mmap().

2025-06-10wifi: rtw88: Rename the RTW_WCPU_11{AC,N} enumsBitterblue Smith
The RTW_WCPU_11AC and RTW_WCPU_11N enums are used to identify two types of microcontrollers used in Realtek chips, but these names are misleading. The "11AC" type was also used in 11n devices (e.g. RTL8733BU, not supported by rtw88), and the "11N" type was also used in 11ac devices (RTL8821AU, RTL8812AU). Rename RTW_WCPU_11AC to RTW_WCPU_3081 and RTW_WCPU_11N to RTW_WCPU_8051. (8051 is well known. It's less clear what 3081 is, but the out of tree drivers use this name.)

2025-06-09scsi: error: alua: I/O errors for ALUA state transitionsRajashekhar M A
When a host is configured with a few LUNs and I/O is running, injecting FC faults repeatedly leads to path recovery problems. The LUNs have 4 paths each and 3 of them come back active after say an FC fault which makes 2 of the paths go down, instead of all 4. This happens after several iterations of continuous FC faults. Reason here is that we're returning an I/O error whenever we're encountering sense code 06/04/0a (LOGICAL UNIT NOT ACCESSIBLE, ASYMMETRIC ACCESS STATE TRANSITION) instead of retrying.

Currently storvsc_timeout is only used in storvsc_sdev_configure(), and 5s and 10s are used elsewhere. It turns out that rarely the 5s is not enough on Azure, so let's use storvsc_timeout everywhere. In case a timeout happens and storvsc_channel_init() returns an error, close the VMBus channel so that any host-to-guest messages in the channel's ringbuffer, which might come late, can be safely ignored.

Calling this packet is necessary when we switch contexts because there are various pieces of state used by userspace to synchronize between BR and BV that are persistent across submits and we need to make sure that they are in a "safe" state when switching contexts. Otherwise a userspace submission in one context could cause another context to function incorrectly and hang, effectively a denial of service (although without leaking data).

2025-06-09scsi: s390: zfcp: Ensure synchronous unit_addPeter Oberparleiter
Improve the usability of the unit_add sysfs attribute by ensuring that the associated FCP LUN scan processing is completed synchronously. This enables configuration tooling to consistently determine the end of the scan process to allow for serialization of follow-on actions. While the scan process associated with unit_add typically completes synchronously, it is deferred to an asynchronous background process if unit_add is used before initial remote port scanning has completed. This occurs when unit_add is used immediately after setting the associated FCP device online. To ensure synchronous unit_add processing, wait for remote port scanning to complete before initiating the FCP LUN scan.

2025-06-09scsi: iscsi: Fix incorrect error path labels for flashnode operationsAlok Tiwari
Correct the error handling goto labels used when host lookup fails in various flashnode-related event handlers: - iscsi_new_flashnode() - iscsi_del_flashnode() - iscsi_login_flashnode() - iscsi_logout_flashnode() - iscsi_logout_flashnode_sid() scsi_host_put() is not required when shost is NULL, so jumping to the correct label avoids unnecessary operations. These functions previously jumped to the wrong goto label (put_host), which did not match the intended cleanup logic. Use the correct exit labels (exit_new_fnode, exit_del_fnode, etc.) to ensure proper error handling. Also remove the unused put_host label under iscsi_new_flashnode() as it is no longer needed.

2025-06-09drm/msm: Temporarily disable stall-on-fault after a page faultConnor Abbott
When things go wrong, the GPU is capable of quickly generating millions of faulting translation requests per second. When that happens, in the stall-on-fault model each access will stall until it wins the race to signal the fault and then the RESUME register is written. This slows processing page faults to a crawl as the GPU can generate faults much faster than the CPU can acknowledge them. It also means that all available resources in the SMMU are saturated waiting for the stalled transactions, so that other transactions such as transactions generated by the GMU, which shares translation resources with the GPU, cannot proceed. This causes a GMU watchdog timeout, which leads to a failed reset because GX cannot collapse when there is a transaction pending and a permanently hung GPU. On older platforms with qcom,smmu-v2, it seems that when one transaction is stalled subsequent faulting transactions are terminated, which avoids this problem, but the MMU-500 follows the spec here. To work around these problems, disable stall-on-fault as soon as we get a page fault until a cooldown period after pagefaults stop. This allows the GMU some guaranteed time to continue working. We only use stall-on-fault to halt the GPU while we collect a devcoredump and we always terminate the transaction afterward, so it's fine to miss some subsequent page faults. We also keep it disabled so long as the current devcoredump hasn't been deleted, because in that case we likely won't capture another one if there's a fault. After this commit HFI messages still occasionally time out, because the crashdump handler doesn't run fast enough to let the GMU resume, but the driver seems to recover from it. This will probably go away after the HFI timeout is increased.

2025-06-09SPI: omap2-mcspi: Fix SPI CS behaviour aroundMark Brown
Merge series from Félix Piédallu <felix.piedallu@non.se.com>: These patches fix the behaviour of the SPI Chip Select of the OMAP2 MCSPI driver used on TI SoCs. The omap2-mcspi driver supports the use of multi mode (multichannel in TI documentation). In this mode, the CS is asserted and deasserted by the hardware. The multi mode is disabled for messages when cs_change=0 for all transfers (e.g when CS is kept asserted between transfers of a same message). The multi mode also needs to be disabled for messages when cs_change=1 on the last transfer (e.g when CS is kept asserted after the WHOLE message), and the message right after. Currently, that is not the case and it CS is deasserted by hardware when it shouldn't. This breaks peripheral drivers that send multiple messages with the CS asserted in between. Patch 1 ensures that multi mode is disabled when cs_change=1 on the last transfer of the message. Patch 2 ensures that multi mode is disable on a message following one with cs_change=1 on the last transfer. This is the case for the TPM TIS SPI driver that uses this logic for flow control purposes. Tested on an AM6442 platform with a TPM ST33HTPH2X32AHE4.

2025-06-09ice: add a separate Rx handler for flow director commandsMichal Kubiak
The "ice" driver implementation uses the control VSI to handle the flow director configuration for PFs and VFs. Unfortunately, although a separate VSI type was created to handle flow director queues, the Rx queue handler was shared between the flow director and a standard NAPI Rx handler. Such a design approach was not very flexible. First, it mixed hotpath and slowpath code, blocking their further optimization. It also created a huge overkill for the flow director command processing, which is descriptor-based only, so there is no need to allocate Rx data buffers. For the above reasons, implement a separate Rx handler for the control VSI. Also, remove from the NAPI handler the code dedicated to configuring the flow director rules on VFs. Do not allocate Rx data buffers to the flow director queues because their processing is descriptor-based only. Finally, allow Rx data queues to be allocated only for VSIs that have netdev assigned to them. This handler splitting approach is the first step in converting the driver to use the Page Pool (which can only be used for data queues). Test hints: 1. Create a VF for any PF managed by the ice driver. 2. In a loop, add and delete flow director rules for the VF, e.g.: for i in {1..128}; do q=$(( i % 16 )) ethtool -N ens802f0v0 flow-type tcp4 dst-port "$i" action "$q" done for i in {0..127}; do ethtool -N ens802f0v0 delete "$i" done Suggested-by: Maciej Fijalkowski <maciej.fijalkowski@intel.com> Suggested-by: Michal Swiatkowski <michal.swiatkowski@intel.com> Acked-by: Maciej Fijalkowski <maciej.fijalkowski@intel.com> Reviewed-by: Jacob Keller <jacob.e.keller@intel.com> Reviewed-by: Przemek Kitszel <przemyslaw.kitszel@intel.com> Reviewed-by: Simon Horman <horms@kernel.org> Signed-off-by: Michal Kubiak <michal.kubiak@intel.com> Tested-by: Rafal Romanowski <rafal.romanowski@intel.com> Signed-off-by: Tony Nguyen <anthony.l.nguyen@intel.com>
