2018-05-25ath10k: add support to configure channel dwell timePradeep Kumar Chitrapu2-3/+21
Configure channel dwell time from duration of the scan request received from mac80211 when the duration is non-zero. When the scan request does not have duration value, use the default ones, the current implementation. Corresponding flag NL80211_EXT_FEATURE_SET_SCAN_DWELL is advertized.

2018-05-23mac80211: Support adding duration for prepare_tx() callbackIlan Peer1-1/+2
There are specific cases, such as SAE authentication exchange, that might require long duration to complete. For such cases, add support for indicating to the driver the required duration of the prepare_tx() operation, so the driver would still be able to complete the frame exchange. Currently, indicate the duration only for SAE authentication exchange, as SAE authentication can take up to 2000 msec (as defined in IEEE P802.11-REVmd D1.0 p. 3504). As the patch modified the prepare_tx() callback API, also modify the relevant code in iwlwifi.

2018-05-14ath10k: re-enable the firmware fallback mechanism for testmodeAndres Rodriguez1-1/+1
The ath10k testmode uses request_firmware_direct() in order to avoid producing firmware load warnings. Disabling the fallback mechanism was a side effect of disabling warnings. We now have a new API that allows us to avoid warnings while keeping the fallback mechanism enabled. So use that instead.

2018-05-12ath10k: fix return value check in wake_tx_q opErik Stromdahl1-1/+1
ath10k_mac_tx_push_txq returns either a postive integer (length) on success or a negative error code on error. The "if (ret) break;" statement will thus always break out of the loop immediately after ath10k_mac_tx_push_txq has returned (making the loop pointless). A side effect of this fix is that we will iterate the queue until ath10k_mac_tx_push_txq returns -ENOENT. This will make sure the queue is not added back to ar->txqs when it is empty. This could potentially improve performance somewhat (I have seen a small improvement with SDIO devices).

2018-04-24wcn36xx: pass information elements in scan requestsDaniel Mack3-7/+18
When the wifi driver core passes IE elements in the scan request, append them to the firmware message. The driver currently tells the core that it is capable of attaching up to WCN36XX_MAX_SCAN_IE_LEN octets, but doesn't actually pass them to the the hardware. Note that this patch doesn't fix a bug that was observed. The change is merely done for the sake of completeness as the hardware supports appending IEs in scans. Tests show that network scans work fine with this patch applied. Some defines were moved around to avoid cyclic include dependencies.

2018-04-24wcn36xx: send bss_type in scan requestsDaniel Mack2-1/+5
Pass the bss_type of the currently configured BSS in the message for the scan request. Therefore, that setting needs to be kept in struct wcn36xx_vif. This seems to be only interesting when scanning for a specific SSID and doesn't matter for regular wildcard scans.

2018-04-24wcn36xx: handle scan cancellation when firmware support is missingDaniel Mack1-3/+11
For firmwares that don't have the SCAN_OFFLOAD feature bit set, do not call into wcn36xx_smd_stop_hw_scan(). Instead, stop the asynchronous work and call into ieee80211_scan_completed() immediately. Signed-off-by: Daniel Mack <daniel@zonque.org> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2018-04-24wcn36xx: cancel pending scan request when interface goes downDaniel Mack1-0/+13
When the network interface goes down while a scan request is still pending that can't be stopped due to firmware hickups, wcn->scan_req remains set, even though the hardware is deinitialized. This results in -EBUSY for all scan requests after the interface was brought up again. Fix this by explicitly completing pending scan requests in wcn36xx_stop().

2018-04-24wcn36xx: abort scan request when 'dequeued' indicator is sentDaniel Mack1-2/+2
When the firmware sends a WCN36XX_HAL_SCAN_IND_DEQUEUED indication, the request is apparently no longer valid. Attempts to stop the hardware scan request subsequently will lead to the following error message, and the hardware is no longer able to communicate with any AP: [ 57.917186] wcn36xx: ERROR hal_stop_scan_offload response failed err=5 Interpreting this indicator message as scan abortion fixes this. While at it, add a newline to a debug print. Signed-off-by: Daniel Mack <daniel@zonque.org> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

2018-04-24ath10k: enable SRRI/DRRI support on ddr for WCN3990Govind Singh6-9/+142
SRRI/DRRI are not mapped in the HW Shadow block and can lead to un-clocked access if common subsystem in the target is powered down due to idle mode. To mitigate this problem SRRI/DRRI can be read from DDR instead of doing an actual hardware read. Host allocates non cached memory on ddr and configures the physical address of this memory to the CE hardware. The hardware updates the RRI on this particular location. Read SRRI/DRRI from DDR location instead of direct target read. Enable retention restore on ddr using hw params to enable in specific targets.

2018-04-24ath10k: enable hw checksum for wcn3990Rakesh Pillai2-2/+18
By default ath10k driver enables the support for HW_CHECKSUM (NETIF_F_HW_CSUM). Since the TCP/UDP checksum calculation is not enabled in the wcn3990 firmware the checksum is incorrect in the TCP/UDP packets and all patckets are dropped. But due note that wcn3990 support in ath10k is still incomplete so this isn't a critical fix (yet). Enable hw checksum calculations in wcn3990 hardware by setting the proper flags in msdu descriptor tso flags.

2018-04-24wcn36xx: pass correct BSS index when deleting BSS keysDaniel Mack3-5/+13
The firmware message to delete BSS keys expects a BSS index to be passed. This field is currently hard-coded to 0. Fix this by passing in the index we received from the firmware when the BSS was configured. The encryption type in that message also needs to be set to what was used when the key was set, so the assignment of vif_priv->encrypt_type is now done after the firmware command was sent. This reportedly fixes the following error in AP mode: wcn36xx: ERROR hal_remove_bsskey response failed err=6 Also, AFAIU, when a BSS is deleted, the firmware apparently drops all the keys associated with it. Trying to remove the key explicitly afterwards will hence lead to the following message: wcn36xx: ERROR hal_remove_bsskey response failed err=16 This is now suppressed with an extra check for the BSS index validity.

2018-04-24ath10k: convert wow pattern from 802.3 to 802.11Wen Gong2-5/+137
When trying to set wow wakeup patterns it fails with this command: iw phyxx wowlan enable patterns offset xx+ IP address xx.xx.xx.xx The reason is that the wow pattern from upper layer is in 802.3 format for this case, it need to convert it to 802.11 format. The input offset parameter is used for 802.3, but the actual offset firmware need depends on rx_decap_mode, so that it needs to be recalculated. Pattern of 802.3 packet is not same with 802.11 packet. If the rx_decap_mode is ATH10K_HW_TXRX_NATIVE_WIFI, then firmware will receive data packet with 802.11 format from hardware. Tested with QCA6174 hw3.0 with firmware WLAN.RM.4.4.1-00099-QCARMSWPZ-1, but this will also affect QCA9377. This has always failed, so it's not a regression with new firmware releases.

The ath10k reports the random_mac_addr capability to upper layer based on the service bit firmware reported. Driver sets the spoofed flag in scan_ctrl_flag to firmware if upper layer has enabled this feature in scan request.

2018-04-19wcn36xx: use READ_ONCE() to access desc->ctrlDaniel Mack1-4/+3
When accessing shared memory to check for the stat of submitted descriptors, make sure to use READ_ONCE(). This will guarantee the compiler treats these memory locations as volatile and doesn't apply any caching. While this doesn't fix any particular problem I ran into, it's best practice to do it this way. Note that this patch also removes the superflous extra condition check in the do-while loop in reap_tx_dxes(), as the loop will break instantly anyway in that case.
