2024-05-03wifi: cfg80211: Clear mlo_links info when STA disconnectsXin Deng1-0/+1
wdev->valid_links is not cleared when upper layer disconnect from a wdev->AP MLD. It has been observed that this would prevent offchannel operations like remain-on-channel which would be needed for user space operations with Public Action frame. Clear the wdev->valid_links when STA disconnects. Signed-off-by: Xin Deng <[email protected]> Link: https://msgid.link/[email protected] Signed-off-by: Johannes Berg <[email protected]>
2024-05-03wifi: iwlwifi: pcie: allocate dummy net_device dynamicallyBreno Leitao3-13/+27
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.

2024-05-03wifi: nl80211: Avoid address calculations via out of bounds array indexingKees Cook1-7/+7
Before request->channels[] can be used, request->n_channels must be set. Additionally, address calculations for memory after the "channels" array need to be calculated from the allocation base ("request") rather than via the first "out of bounds" index of "channels", otherwise run-time bounds checking will throw a warning.

2024-05-02wifi: ath12k: fix the problem that down grade phy mode operationLingbo Kong1-3/+13
Currently, when using WCN7850 or QCN9274 as AP, ath12k always performs down grade phy mode operation regardless of whether the firmware supports EHT capability or not and then vdev will start in HE mode. When stations that support EHT capability try to connect to the AP, the AP will set phy mode to EHT after receiving the association request packet, and then send WMI_PEER_ASSOC_CMDID command to firmware, AP’s firmware will crash. This is because when the ath12k_mac_copy_sband_iftype_data() function handles EHT capability, it does not copy the EHT capability into the iftype[band][type] array according to the interface type. So, interface type should not be used as an index to get eht_cap in ath12k_mac_check_down_grade_phy_mode() function. To address this issue, use types_mask to select the eht_cap in ath12k_mac_check_down_grade_phy_mode() function. This patch affects QCN9274 and WCN7850 because they have the same issue.
