2025-02-11wifi: iwlwifi: properly set the names for SC devicesEmmanuel Grumbach3-15/+37
Sc devices can come with several CRFs. Use the CRF to determine the name of the device.

2025-02-11wifi: iwlwifi: make no_160 more genericEmmanuel Grumbach5-112/+123
We'll have devices that are EHT capable but don't support 320 MHz and those devices look like the 320 MHz capable devices, but have distinct subsystem ID. We already had the same type of differentiation for HE devices that support 160 MHz or not. Enhance that mechanism and now the _IWL_DEV_INFO macro gets an indication whether the bandwidth should be limited for that specific device. The subsystem ID gives a binary answer about the bandwidth limitation and iwl_pci_find_dev_info() compares this to the list of _IWL_DEV_INFO entries.

2025-02-11wifi: iwlwifi: be less aggressive with re-probeEmmanuel Grumbach1-1/+1
Re-probing if we had 2 firmware crash within 3 minutes is really too aggressive. Drastically reduce the threshold to 7 seconds. After 7 seconds, a new firmware crash will be considered "new" and not cause a PCI re-probe. This allows to pass tests that cause a firmware crash every 10 seconds and expect to see no impact on the traffic.

During reprobe, the sw state is being destroyd, and so is the connection. When the peer STA is being removed, the opmode sends a command to flush the TXQs of the STA and uses iwl_trans_wait_txq_empty. This one warns if the FW is not alive, but it really shouldn't if there is a FW error - and return silently instead, just like we do when sending a hcmd.

2025-02-11wifi: qtnfmac: Avoid multiple -Wflex-array-member-not-at-end warningsGustavo A. R. Silva1-8/+13
-Wflex-array-member-not-at-end was introduced in GCC-14, and we are getting ready to enable it, globally. So, in order to avoid ending up with a flexible-array member in the middle of other structs, we use the `__struct_group()` helper to create a new tagged `struct qlink_tlv_hdr_fixed`. This structure groups together all the members of the flexible `struct qlink_tlv_hdr` except the flexible array. As a result, the array is effectively separated from the rest of the members without modifying the memory layout of the flexible structure. We then change the type of the middle struct member currently causing trouble from `struct qlink_tlv_hdr` to `struct qlink_tlv_hdr_fixed`. We also want to ensure that when new members need to be added to the flexible structure, they are always included within the newly created tagged struct. For this, we use `static_assert()`. This ensures that the memory layout for both the flexible structure and the new tagged struct is the same after any changes. This approach avoids having to implement `struct qlink_tlv_hdr_fixed` as a completely separate structure, thus preventing having to maintain two independent but basically identical structures, closing the door to potential bugs in the future. So, with this changes, fix 66 of the following warnings: drivers/net/wireless/quantenna/qtnfmac/qlink.h:1681:30: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] drivers/net/wireless/quantenna/qtnfmac/qlink.h:1660:30: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] drivers/net/wireless/quantenna/qtnfmac/qlink.h:1646:30: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] drivers/net/wireless/quantenna/qtnfmac/qlink.h:1621:30: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] drivers/net/wireless/quantenna/qtnfmac/qlink.h:1609:30: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] drivers/net/wireless/quantenna/qtnfmac/qlink.h:1570:30: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] Signed-off-by: Gustavo A.

Driver selects firmware by hardware version, which normally can be read from registers before selecting firmware.

With previous patch "wifi: ath11k: move update channel list from update reg worker to reg notifier", ath11k_reg_update_chan_list() will be called during reg_process_self_managed_hint(). reg_process_self_managed_hint() will hold rtnl_lock all the time. But ath11k_reg_update_chan_list() may increase the occupation time of rtnl_lock, because when wait flag is set, wait_for_completion_timeout() will be called during 11d/hw scan. Should minimize the occupation time of rtnl_lock as much as possible to avoid interfering with rest of the system. So move the update channel list operation to a new worker, so that wait_for_completion_timeout() won't be called and will not increase the occupation time of rtnl_lock.

2025-02-06wifi: ath11k: update channel list in reg notifier instead reg workerWen Gong1-7/+15
Currently when ath11k gets a new channel list, it will be processed according to the following steps: 1. update new channel list to cfg80211 and queue reg_work. 2. cfg80211 handles new channel list during reg_work. 3. update cfg80211's handled channel list to firmware by ath11k_reg_update_chan_list(). But ath11k will immediately execute step 3 after reg_work is just queued. Since step 2 is asynchronous, cfg80211 may not have completed handling the new channel list, which may leading to an out-of-bounds write error: BUG: KASAN: slab-out-of-bounds in ath11k_reg_update_chan_list Call Trace: ath11k_reg_update_chan_list+0xbfe/0xfe0 [ath11k] kfree+0x109/0x3a0 ath11k_regd_update+0x1cf/0x350 [ath11k] ath11k_regd_update_work+0x14/0x20 [ath11k] process_one_work+0xe35/0x14c0 Should ensure step 2 is completely done before executing step 3. Thus Wen raised patch[1]. When flag NL80211_REGDOM_SET_BY_DRIVER is set, cfg80211 will notify ath11k after step 2 is done. So enable the flag NL80211_REGDOM_SET_BY_DRIVER then cfg80211 will notify ath11k after step 2 is done. At this time, there will be no KASAN bug during the execution of the step 3.

Host receives four Transmit Power Control(TPC) events from firmware on sending TPC request. Fixed param TLV is present as part of all event to indicate the event count and end of event. TPC config parameters along with regulatory power array comes as first event. Rates array comes as second and third event as it cannot be packed in single event. Conformance Test Limit (CTL) power array comes as the fourth event. Firmware packs different sets of array params which includes array length and type inside master TLV as different subtlvs. And the actual content of array is packed one after the other inside a separate TLV as single buffer. Parse various events and save it in local structures. Create tpc_stats file using debugfs to store these local structures. Create function to handle TPC stats read to relay the information to the user.
