smatch flagged the following issue: drivers/net/wireless/ath/ath11k/qmi.c:2401 ath11k_qmi_load_file_target_mem() error: uninitialized symbol 'ret'. The reality is that 'ret' is initialized in every path through ath11k_qmi_load_file_target_mem() except one, the case where the input 'len' is 0, and hence the "while (remaining)" loop is never entered. But to make sure this case is also handled, add an initializer to the declaration of 'ret'. No functional changes, compile tested only. Signed-off-by:

In ath12k_mac_op_assign_vif_chanctx(), there is a logic to create peer using ar->mac_addr for a STA vdev. This is invalid because a STA vdev should have a peer created using AP's MAC address. Besides, if we run into that logic, it means a peer has already been created earlier, we should not create it again. So remove it.

ath12k_mac_op_unassign_vif_chanctx() will do vdev stop in ath12k_mac_monitor_stop(). This ath12k_mac_vdev_stop() will do vdev stop again, then might trigger firmware crash.

Currently memory allocation for multiple hardware rings done in host as these memory will be used by firmware/hardware. But in case of tcl_cmd_ring and tcl_status_ring neither firmware nor hardware uses host allocated memory and it uses memory allocated by firmware itself. So avoid tcl_cmd_ring and tcl_status_ring setup in host. Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1 Signed-off-by:

Embedding net_device into structures prohibits the usage of flexible arrays in the net_device structure. For more details, see the discussion at [1]. Un-embed the net_device from struct wil6210_priv by converting it into a pointer. Then use the leverage alloc_netdev_dummy() to allocate the net_device object at wil_if_add(). The free of the device occurs at wil_if_remove(). Link: https://lore.kernel.org/all/20240229225910.79e224cf@kernel.org/ [1] Signed-off-by:

If STATUS_BUFFER_DONE is not set for a monitor status ring entry, we don't process the status ring until STATUS_BUFFER_DONE set for that status ring entry. During LMAC reset it may happen that hardware will not write STATUS_BUFFER_DONE tlv in status buffer, in that case we end up waiting for STATUS_BUFFER_DONE leading to backpressure on monitor status ring. To fix the issue, when HP (Head Pointer) + 1 entry is peeked and if DMA is not done and if HP + 2 entry's DMA done is set, replenish HP + 1 entry and start processing in next interrupt. If HP + 2 entry's DMA done is not set, poll onto HP + 1 entry DMA done to be set. Also, during monitor attach HP points to the end of the ring and TP (Tail Pointer) points to the start of the ring. Using ath11k_hal_srng_src_peek() may result in processing invalid buffer for the very first interrupt. Since, HW starts writing buffer from TP. To avoid this issue call ath11k_hal_srng_src_next_peek() instead of calling ath11k_hal_srng_src_peek(). Tested-on: IPQ5018 hw1.0 AHB WLAN.HK.2.6.0.1-00861-QCAHKSWPL_SILICONZ-1 Signed-off-by:

In mesh node traffic, internal firmware-transmitted failures are reported as transmitted failures in mesh metric calculation, leading to the breakage of the mesh link. Fix the issue by dropping the internal firmware-transmitted failures before updating the TX completion status to mac80211, in order to prevent false failure averaging in mesh metric calculation.

When a station idles for a long time, hostapd will try to send a QoS Null frame to the station as "poll". NL80211_CMD_PROBE_CLIENT is used for this purpose. And the skb will be added to ack_status_frame - waiting for a completion via ieee80211_report_ack_skb(). But when the peer was already removed before the tx_complete arrives, the peer will be missing. And when using dev_kfree_skb_any (instead of going through mac80211), the entry will stay inside ack_status_frames thus not clean up related information in its internal data structures. This IDR will therefore run full after 8K request were generated for such clients. At this point, the access point will then just stall and not allow any new clients because idr_alloc() for ack_status_frame will fail. ieee80211_free_txskb() on the other hand will (when required) call ieee80211_report_ack_skb() and make sure that (when required) remove the entry from the ack_status_frame and clean up related information in its internal data structures.

Currently, inter device MLO is not supported. Therefore, the WBM idle ring buffers choose the implicit return buffer manager (DEV0_IDLE_DESC_LIST). However, this implicit return buffer manager design is not meeting the requirements to support inter device MLO. In inter device MLO, multiple devices participate. The device specific WBM idle ring buffers transmit to multiple device REO rings. To distinguish between device specific WBM idle buffers, the setup configuration need to choose a different return buffer manager based on the unique identifier (device index).

Introduce a device index parameter in the ath12k_base structure. This value is used as unique identifier for devices involved in Inter-device MLO. It is also used to configure the MLO parameter within the QMI host capability send request. While currently set to zero, future logic will be added for inter device support to populate this parameter with non-zero values.

Currently, the WBM idle ring descriptor setup uses implicit value HAL_RX_BUF_RBM_WBM_DEV0_IDLE_DESC_LIST for the return buffer manager parameter. To support inter-device MLO (Multi-link operation), this parameter needs to be configure dynamically based on the device identifier within the MLO group. Therefore, introduce a new argument to the helper function ath12k_hal_set_link_desc_addr(). Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1 Signed-off-by:

Currently, in ath11k_ahb_probe(), if a failure occurs after ath11k_ahb_ce_remap() is called, and if hw_params->ce_remap is enabled, the CE register memory is not unmapped. So add a call to ath11k_ahb_ce_unmap() in the error path. This issue was identified by smatch/smatch_scripts/kchecker: drivers/net/wireless/ath/ath11k/ahb.c:1218 ath11k_ahb_probe() warn: 'ab->mem_ce' from ioremap() not released on lines: 1218. Since this is a rare error path with no simple way to test, and since the change is trivial to review, compile tested only. Signed-off-by:

Currently the logic that handles hw_params->ce_remap is inline code, both for doing the remap and the unmap. An upcoming change needs to do the unmap in a second place, so refactor the unmap logic into a separate function. And although it is only called from one place, refactor the remap logic as well to have functional symmetry. No functional changes, compile tested only. Signed-off-by:

Currently, hardware state is not protected across the reconfigure operations. However, in single wiphy models, multiple radio/links is exposed as a MAC hardware (ieee80211_hw) through the driver hardware abstraction (ath12k_hw) layer. In such scenario, we need to protect hardware state across the multiple radio/link at the driver hardware abstraction (ath12k_hw) layer. Therefore, introduce a new mutex in the ath12k_hw layer.

Currently, in multi wiphy models, the mac80211 hardware state is maintained within the radio/link structure. However, in single wiphy models, the mac80211 hardware state is needed at the hardware abstraction layer (ath12k_hw). Therefore, move the hardware state from the radio/link structure to the hardware abstraction layer (ath12k_hw). Additionally, update the naming convention of the state enums to enhance clarity and consistency. Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1 Signed-off-by:

Currently, in multi-wiphy models, the recovery handler access mac80211 HW from the radio/link structure. This will be incorrect for single wiphy model, as they will hold multiple link/radio structures. To fix this, access mac80211 HW based on the number of hardware in the SoC/chip. This approach makes the recovery handler compatible with both multi wiphy and single wiphy models. Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1 Signed-off-by:

struct net_device shouldn't be embedded into any structure, instead, the owner should use the priv space to embed their state into net_device. Embedding net_device into structures prohibits the usage of flexible arrays in the net_device structure. For more details, see the discussion at [1]. Un-embed the net_device from struct iwl_trans_pcie by converting it into a pointer. Then use the leverage alloc_netdev() to allocate the net_device object at iwl_trans_pcie_alloc. The private data of net_device becomes a pointer for the struct iwl_trans_pcie, so, it is easy to get back to the iwl_trans_pcie parent given the net_device object.
