Zero-length arrays are deprecated and we are moving towards adopting C99 flexible-array members, instead. So, replace zero-length arrays declarations in anonymous union with the new DECLARE_FLEX_ARRAY() helper macro. This helper allows for flexible-array members in unions.

In preparation for reducing the use of ksize(), explicitly track the size of scan_cmd allocations. This also allows for noticing if the scan size changes unexpectedly. Note that using ksize() was already incorrect here, in the sense that ksize() would not match the actual allocation size, which would trigger future run-time allocation bounds checking. (In other words, memset() may know how large scan_cmd was allocated for, but ksize() will return the upper bounds of the actually allocated memory, causing a run-time warning about an overflow.)

When STA roams from one AP to another, after roam is complete, host driver tries to get TIM information from firmware. This is no longer supported in the firmware & hence, this call will always fail. This failure results in the below message being displayed on the console all the time when roam is done. ieee80211 phy0: brcmf_update_bss_info: wl dtim_assoc failed (-52) Changes ensure that the host driver will no longer try to get TIM information from firmware.

The bug is here: "} else if (item) {". The list iterator value will *always* be set and non-NULL by list_for_each_entry(), so it is incorrect to assume that the iterator value will be NULL if the list is empty or no element is found in list. Use a new value 'iter' as the list iterator, while use the old value 'item' as a dedicated pointer to point to the found element, which 1. can fix this bug, due to now 'item' is NULL only if it's not found. 2. do not need to change all the uses of 'item' after the loop. 3. can also limit the scope of the list iterator 'iter' *only inside* the traversal loop by simply declaring 'iter' inside the loop in the future, as usage of the iterator outside of the list_for_each_entry is considered harmful. https://lkml.org/lkml/2022/2/17/1032 Fixes: a910e4a9 ("cw1200: add driver for the ST-E CW1100 & CW1200 WLAN chipsets") Signed-off-by:Xiaomeng Tong <xiam0nd.tong@gmail.com> Signed-off-by:

We are seeing system hangs during WoWLAN suspend, and get below two stacks: Stack1: [ffffb02cc1557b20] __schedule at ffffffff8bb10860 [ffffb02cc1557ba8] schedule at ffffffff8bb10f24 [ffffb02cc1557bb8] schedule_timeout at ffffffff8bb16d88 [ffffb02cc1557c30] wait_for_completion at ffffffff8bb11778 [ffffb02cc1557c78] __flush_work at ffffffff8b0b30cd [ffffb02cc1557cf0] __cancel_work_timer at ffffffff8b0b33ad [ffffb02cc1557d60] ath11k_mac_drain_tx at ffffffffc0c1f0ca [ath11k] [ffffb02cc1557d70] ath11k_wow_op_suspend at ffffffffc0c5201e [ath11k] [ffffb02cc1557da8] __ieee80211_suspend at ffffffffc11e2bd3 [mac80211] [ffffb02cc1557dd8] wiphy_suspend at ffffffffc0f901ac [cfg80211] [ffffb02cc1557e08] dpm_run_callback at ffffffff8b75118a [ffffb02cc1557e38] __device_suspend at ffffffff8b751630 [ffffb02cc1557e70] async_suspend at ffffffff8b7519ea [ffffb02cc1557e88] async_run_entry_fn at ffffffff8b0bf4ce [ffffb02cc1557ea8] process_one_work at ffffffff8b0b1a24 [ffffb02cc1557ee0] worker_thread at ffffffff8b0b1c4a [ffffb02cc1557f18] kthread at ffffffff8b0b9cb8 [ffffb02cc1557f50] ret_from_fork at ffffffff8b001d32 Stack2: [ffffb02cc00b7d18] __schedule at ffffffff8bb10860 [ffffb02cc00b7da0] schedule at ffffffff8bb10f24 [ffffb02cc00b7db0] schedule_preempt_disabled at ffffffff8bb112b4 [ffffb02cc00b7db8] __mutex_lock at ffffffff8bb127ea [ffffb02cc00b7e38] ath11k_mgmt_over_wmi_tx_work at ffffffffc0c1aa44 [ath11k] [ffffb02cc00b7ea8] process_one_work at ffffffff8b0b1a24 [ffffb02cc00b7ee0] worker_thread at ffffffff8b0b1c4a [ffffb02cc00b7f18] kthread at ffffffff8b0b9cb8 [ffffb02cc00b7f50] ret_from_fork at ffffffff8b001d32 From the first stack, ath11k_mac_drain_tx calls cancel_work_sync(&ar->wmi_mgmt_tx_work) and waits all packets to be sent out or dropped. However, we find from Stack2 that this work item is blocked because ar->conf_mutex is already held by ath11k_wow_op_suspend. Fix this issue by moving ath11k_mac_wait_tx_complete to the start of ath11k_wow_op_suspend where ar->conf_mutex has not been acquired. And this change also makes the logic in ath11k_wow_op_suspend match the logic in ath11k_mac_op_start and ath11k_mac_op_stop.

There are two types of 160 MHz spectral scan support mentioned below 1. Fragmented approach 2. Single event approach In this fragmented approach, single 160 MHz will be split as two 80 MHz buffer. First fft sample buffer will contain spectral scan result of primary 80 MHz and the second fft sample buffer will contain secondary 80 MHz and here cfreq1 and cfreq2 will be mentioned. In case of 160 MHz on 36th channel will contain cfreq1 as 5210 and cfreq2 as 5290. Chipsets which support this approach are IPQ8074/IPQ6018. Replacing freq1 with freq2 in every secondary sepctral scan event to distinguish between two different 80 MHz spectral event data. In the 2nd approach each fft sample buffer will contain spectral scan result for whole 160 MHz by mentioning cfreq1 as 5250 which is center frequency of whole 160 MHz. Chipset which support this approach is QCN9074. Host will receive spectral event from target for every 5 fft samples.

The cause of this error has been investigated and we found that this is related to the WiFi Fast Transaction feature. We observed that this is triggered when the router tells the device to change band. In this case the device first auth to the other band and then the disconnect path from the prev band is triggered. This is problematic with the current rhash implementation since the addrs is used as key and the logic of "adding first, delete later" conflicts with the rhash logic. In fact peer addition will fail since the peer is already added and with that fixed a peer deletion will cause unitended effect by removing the peer just added. Current solution to this is to add additional logic to the peer delete, make sure we are deleting the correct peer taken from the rhash table (and fallback to the peer list) and for the peer add logic delete the peer entry for the rhash list before adding the new one (counting as an error only when a peer with the same vlan_id is asked to be added). With this change, a sta can correctly transition from 2.4GHz and 5GHZ with no drop and no error are printed.

Check IEEE80211_TX_CTL_NO_CCK_RATE flag to avoid sending frames with CCK rates in 2GHz band. In TX flow, add IEEE80211_TX_CTL_NO_CCK_RATE flag to check and get its lowest rate without CCK rates if the TX type is mgmt frames or data frames. Besides, the decision of phy rate and retry rate in P2P mode are also be handled. In P2P GO mode, it should send beacon of no CCK rates in its frame rate. Therefore, We add a condition to decide which rate is added to beacon content. Moreover, we avoid setting a mask of rates to be used for rate control selection before and after connection in P2P mode. Signed-off-by:
