2024-05-06wifi: iwlwifi: mvm: trigger link selection after exiting EMLSRMiri Korenblit
If the reason for exiting EMLSR was a blocking reason, wait for the corresponding unblocking event: - if there is an ongoing scan - do nothing. Link selection will be triggered at the end of it. - If more than 30 seconds passed since the exit, trigger MLO scan, which will trigger link selection - If less then 30 seconds passed since exit, reuse the latest link selection result If the reason for exiting EMLSR was an exit reason (IWL_MVM_EXIT_*), schedule MLO scan in 30 seconds.

2024-05-06wifi: iwlwifi: cleanup EMLSR when BT is active handlingMiri Korenblit
BT Coex disables EMLSR only for a 2.4 GHz link, but doesn't block the vif from using EMLSR with a different link pair. In addition, storing it in mvmvif:disable_esr_reason requires extracting the BT Coex bit before checking if EMLSR is blocked or not for a specific vif. Therefore, change the BT Coex bit to be an exit reason and not a blocker. On link selection, EMLSR mode will be re-calculated for the 2.4 GHz link instead of checking that bit. While at it, move the relevant function declarations to the EMLSR functions area in mvm.h Signed-off-by: Miri Korenblit <miriam.rachel.korenblit@intel.com> Link: https://msgid.link/20240505091420.a2e93b67c895.I183a0039ef076613144648cc46fbe9ab3d47c574@changeid Signed-off-by: Johannes Berg <johannes.berg@intel.com>

To fix these issues, We removed the rtw89_hci_disable_intr() and rtw89_hci_enable_intr() during rtw89_wow_swap_fw() to prevent add packet offload can't receive c2h back due to interrupt disable. Only 8852C and 8922A needs to disable interrupt before downloading fw. Furthermore, we avoid using low power HCI mode on WoWLAN mode, to prevent interrupt enabled, then get interrupt and calculate RXBD mismatched due to software RXBD index already reset but hardware RXBD index not yet.

2024-05-03wifi: ath12k: Don't drop tx_status in failure caseSven Eckelmann
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.

2024-05-03wifi: ath12k: add multi device support for WBM idle ring buffer setupKarthikeyan Periyasamy
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).

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.

2024-05-03wifi: ath12k: Refactor the hardware recovery procedureKarthikeyan Periyasamy
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.

2024-05-03wifi: iwlwifi: pcie: allocate dummy net_device dynamicallyBreno Leitao
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.

This appears to work around a deadlock regression that came in with the LED merge in 6.9.
