2021-11-17ath11k: clear the keys properly via DISABLE_KEYKarthikeyan Kathirvel
DISABLE_KEY sets the key_len to 0, firmware will not delete the keys if key_len is 0. Changing from security mode to open mode will cause mcast to be still encrypted without vdev restart. Set the proper key_len for DISABLE_KEY cmd to clear the keys in firmware.

2021-11-17ath11k: add support for BSS color changeJohn Crispin
Whenever the MAC detects a color collision, or any of its associated stations detects one, the firmware will send out an event. Add the code to parse and handle this event and pass the data up to mac80211. The firmware does not provide an offload feature such as the one used for CSA. The color change process is hence triggered via the beacon offload tx completion events sent out by firmware. BSS color feature is enabled depending on service flag advertised by firmware, based on which color change functionality is invoked.

2021-11-17ath11k: Disabling credit flow for WMI pathP Praneesh
Firmware credit flow control is enabled for WMI control services, which expects available tokens should be acquired before sending a command to the target. Also the token gets released when firmware receives the command. This credit-based flow limits driver to send WMI command only when the token available which is causing WMI commands to timeout and return -EAGAIN, whereas firmware has enough capability to process the WMI command. To fix this Tx starvation issue, introduce the ability to disable the credit flow for the WMI path. The driver sends WMI configuration for disabling credit flow to firmware by two ways. 1. By using a global flag (HTC_MSG_SETUP_COMPLETE_EX_ID msg type flags) 2. By using a local flag (ATH11K_HTC_CONN_FLAGS_DISABLE_CREDIT_FLOW_CTRL = 1 << 3) Ath11k uses both these configurations to disable credit flow for the WMI path completely. Also added a hw_param member for credit flow control by which we can enable or disable it based on per-target basis. Currently we are disabling credit flow for IPQ8074, IPQ6018, and QCN9074 as recommended by firmware.

2021-11-15ath11k: avoid unnecessary BH disable lock in STA kickout eventKarthikeyan Periyasamy
In STA kickout event processing, the peer object is protected under spin lock BH. Release this lock after picking up the vdev_id from the peer object instead after ieee80211_report_low_ack(). This will minimize the lock hold period which will improve performance since base_lock is used across the data path. This was found in code review.

AUTH flag is needed when peer assoc command is sent from host in security mode for non-assoc cases. Firmware will handle AUTH flag when client is associating as AUTH flag will be set after key exchange. For internally provided peer assoc commands from host, there won't be any key exchange, so AUTH flag is expected to be set in host.

2021-09-28ath11k: add handler for scan event WMI_SCAN_EVENT_DEQUEUEDWen Gong
When wlan interface is up, 11d scan is sent to the firmware, and the firmware needs to spend couple of seconds to complete the 11d scan. If immediately a normal scan from user space arrives to ath11k, then the normal scan request is also sent to the firmware, but the scan started event will be reported to ath11k until the 11d scan complete. When timed out for the scan started in ath11k, ath11k stops the normal scan and the firmware reports WMI_SCAN_EVENT_DEQUEUED to ath11k for the normal scan. ath11k has no handler for the event and then timed out for the scan completed in ath11k_scan_stop(), and ath11k prints the following error message.

2021-09-28ath11k: Add vdev start flag to disable hardware encryptionSeevalamuthu Mariappan
Firmware blocks all data traffic until the key is plumbed. But, with software encryption mode, key is never plumbed to firmware. Due to this, a traffic failure in software encryption mode has been observed. Hence, firmware has introduced a flag to differentiate software encryption mode. This flag can be passed during vdev_start command. Enable WMI_VDEV_START_HW_ENCRYPTION_DISABLED flag in vdev_start command to notify firmware to disable hardware encryption for a vdev. This is set if raw mode software encryption is enabled.

2021-09-28ath11k: Avoid race during regd updatesSriram R
Whenever ath11k is bootup with a user country already set, cfg80211 notifies this country info to ath11k soon after registration, where the notification is sent to the firmware for fetching the rules of this user country input. Multiple race conditions could be seen in this scenario where a new request is either lost as pointed in [1] or a new regd overwrites the default regd provided by the firmware during bootup. Note that, the default regd is used for intersection purpose and hence it should not be overwritten. The main reason as pointed by [1] is the usage of ATH11K_FLAG_REGISTERED flag which is updated after completion of core registration, whereas the reg notification from cfg80211 and wmi events for the corresponding request can happen much before that. Since the ATH11K_FLAG_REGISTERED is currently used to determine if the event containing reg rules belong to default regd or for user request, there is a possibility of the default regd getting overwritten. Since the default reg rules will be received only once per pdev on firmware load, the above flag based check can be replaced with a check to see if default_regd is already set, so that we can now always update the new_regd. Also if the new_regd is set, this will be always used to update the reg rules for the registered phy.

2021-09-28ath11k: Avoid reg rules update during firmware recoverySriram R
During firmware recovery, the default reg rules which are received via WMI_REG_CHAN_LIST_CC_EVENT can overwrite the currently configured user regd. See below snap for example, root@OpenWrt:/# iw reg get | grep country country FR: DFS-ETSI country FR: DFS-ETSI country FR: DFS-ETSI country FR: DFS-ETSI root@OpenWrt:/# echo assert > /sys/kernel/debug/ath11k/ipq8074\ hw2.0/simulate_f w_crash <snip> [ 5290.471696] ath11k c000000.wifi1: pdev 1 successfully recovered root@OpenWrt:/# iw reg get | grep country country FR: DFS-ETSI country US: DFS-FCC country US: DFS-FCC country US: DFS-FCC In the above, the user configured country 'FR' is overwritten when the rules of default country 'US' are received and updated during recovery. Hence avoid processing of these rules in general during firmware recovery as they have been already applied during driver registration or after last set user country is configured. This scenario applies for both AP and STA devices basically because cfg80211 is not aware of the recovery and only the driver recovers, but changing or resetting of the reg domain during recovery is not needed so as to continue with the configured regdomain currently in use.

2021-09-28ath11k: Replace one-element array with flexible-array memberGustavo A. R. Silva
There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure. Kernel code should always use "flexible array members"[1] for these cases. The older style of one-element or zero-length arrays should no longer be used[2]. Refactor the code a bit according to the use of a flexible-array member in struct scan_chan_list_params instead of a one-element array, and use the struct_size() helper. Also, save 25 (too many) bytes that were being allocated: $ pahole -C channel_param drivers/net/wireless/ath/ath11k/reg.o struct channel_param { u8 chan_id; /* 0 1 */ u8 pwr; /* 1 1 */ u32 mhz; /* 2 4 */ /* Bitfield combined with next fields */ u32 half_rate:1; /* 4:16 4 */ u32 quarter_rate:1; /* 4:17 4 */ u32 dfs_set:1; /* 4:18 4 */ u32 dfs_set_cfreq2:1; /* 4:19 4 */ u32 is_chan_passive:1; /* 4:20 4 */ u32 allow_ht:1; /* 4:21 4 */ u32 allow_vht:1; /* 4:22 4 */ u32 allow_he:1; /* 4:23 4 */ u32 set_agile:1; /* 4:24 4 */ u32 psc_channel:1; /* 4:25 4 */ /* XXX 6 bits hole, try to pack */ u32 phy_mode; /* 8 4 */ u32 cfreq1; /* 12 4 */ u32 cfreq2; /* 16 4 */ char maxpower; /* 20 1 */ char minpower; /* 21 1 */ char maxregpower; /* 22 1 */ u8 antennamax; /* 23 1 */ u8 reg_class_id; /* 24 1 */ /* size: 25, cachelines: 1, members: 21 */ /* sum members: 23 */ /* sum bitfield members: 10 bits, bit holes: 1, sum bit holes: 6 bits */ /* last cacheline: 25 bytes */ } __attribute__((__packed__)); as previously, sizeof(struct scan_chan_list_params) was 32 bytes: $ pahole -C scan_chan_list_params drivers/net/wireless/ath/ath11k/reg.o struct scan_chan_list_params { u32 pdev_id; /* 0 4 */ u16 nallchans; /* 4 2 */ struct channel_param ch_param[1]; /* 6 25 */ /* size: 32, cachelines: 1, members: 3 */ /* padding: 1 */ /* last cacheline: 32 bytes */ }; and now with the flexible array transformation it is just 8 bytes: $ pahole -C scan_chan_list_params drivers/net/wireless/ath/ath11k/reg.o struct scan_chan_list_params { u32 pdev_id; /* 0 4 */ u16 nallchans; /* 4 2 */ struct channel_param ch_param[]; /* 6 0 */ /* size: 8, cachelines: 1, members: 3 */ /* padding: 2 */ /* last cacheline: 8 bytes */ }; This helps with the ongoing efforts to globally enable -Warray-bounds and get us closer to being able to tighten the FORTIFY_SOURCE routines on memcpy().
