2021-09-28ath10k: high latency fixes for beacon bufferAlagu Sankar
Beacon buffer for high latency devices does not use DMA. other similar buffer allocation methods in the driver have already been modified for high latency path. Fix the beacon buffer allocation left out in the earlier high latency changes.

2021-03-06ath10k: Detect conf_mutex held ath10k_drain_tx() callsShuah Khan
ath10k_drain_tx() must not be called with conf_mutex held as workers can use that also. Add call to lockdep_assert_not_held() on conf_mutex to detect if conf_mutex is held by the caller. The idea for this patch stemmed from coming across the comment block above the ath10k_drain_tx() while reviewing the conf_mutex holds during to debug the conf_mutex lock assert in ath10k_debug_fw_stats_request(). Adding detection to assert on conf_mutex hold will help detect incorrect usages that could lead to locking problems when async worker routines try to call this routine.

2021-01-28ath10k: fix wmi mgmt tx queue full due to race conditionMiaoqing Pan
Failed to transmit wmi management frames: [84977.840894] ath10k_snoc a000000.wifi: wmi mgmt tx queue is full [84977.840913] ath10k_snoc a000000.wifi: failed to transmit packet, dropping: -28 [84977.840924] ath10k_snoc a000000.wifi: failed to submit frame: -28 [84977.840932] ath10k_snoc a000000.wifi: failed to transmit frame: -28 This issue is caused by race condition between skb_dequeue and __skb_queue_tail. The queue of ‘wmi_mgmt_tx_queue’ is protected by a different lock: ar->data_lock vs list->lock, the result is no protection. So when ath10k_mgmt_over_wmi_tx_work() and ath10k_mac_tx_wmi_mgmt() running concurrently on different CPUs, there appear to be a rare corner cases when the queue length is 1, CPUx (skb_deuque) CPUy (__skb_queue_tail) next=list prev=list struct sk_buff *skb = skb_peek(list); WRITE_ONCE(newsk->next, next); WRITE_ONCE(list->qlen, list->qlen - 1);WRITE_ONCE(newsk->prev, prev); next = skb->next; WRITE_ONCE(next->prev, newsk); prev = skb->prev; WRITE_ONCE(prev->next, newsk); skb->next = skb->prev = NULL; list->qlen++; WRITE_ONCE(next->prev, prev); WRITE_ONCE(prev->next, next); If the instruction ‘next = skb->next’ is executed before ‘WRITE_ONCE(prev->next, newsk)’, newsk will be lost, as CPUx get the old ‘next’ pointer, but the length is still added by one. The final result is the length of the queue will reach the maximum value but the queue is empty. So remove ar->data_lock, and use 'skb_queue_tail' instead of '__skb_queue_tail' to prevent the potential race condition. Also switch to use skb_queue_len_lockless, in case we queue a few SKBs simultaneously.

2021-01-28ath10k: pass the ssid info to get the correct bss entityWen Gong
When connect to an AP with WPA mode, ath10k need to set need_ptk_4_way to firmware in WMI_PEER_ASSOC_CMD, then the data path is disallow in firmware, it will be allowed untill firmware finish the 4 way handshake. It failed with a test case with below steps: 1. configure AP with WPA mode with ssid1 SimpleConnect_a_orbvt_ch1, bssid1 and channel 1. 2. connect to ssid1 and ping success. 3. wait 10 seconds which is less than IEEE80211_SCAN_RESULT_EXPIRE(30 seconds). 4. configure AP with OPEN mode with ssid2 SimpleConnect_b_z3a00_ch1, but use same bssid1 and channel 1 of step 1. 5. disconnect ssid1. 6. connect to ssid2 and ping fail. Fail reason: When run step 6, ath10k_peer_assoc_h_crypto() called cfg80211_get_bss() with bssid and chan info, but ssid1 and ssid2 have the same bssid and channel, then there have 2 entry for ssid1 and ssid2 in cfg80211. The ssid1's order is before ssid2 in bss_list, and ssid1's age is less than the expire time which is IEEE80211_SCAN_RESULT_EXPIRE(30 seconds). Then ssid1's entry is selected and ath10k_peer_assoc_h_crypto() parsed it and get the rsnie and then need_ptk_4_way is set to firmware, so data path is disallowed and it will not receive 4 way handshake for OPEN mode, so ping fail in step 6. This patch is to pass the ssid info to cfg80211_get_bss() as same as cfg80211_mlme_assoc() and cfg80211_mlme_auth(), then it will find the correct bss entry in above test case, then case success. For AP mode, the ssid info is filled in ieee80211_start_ap(), for STATION mode, it is filled in ieee80211_mgd_assoc(). Tested for both AP/STATION mode with QCA6174 hw3.2 PCI, it is success start/connect/ping for WPA/OPEN mode.

2021-01-28ath10k: allow dynamic SAR power limits via common APICarl Huang
ath10k assigns ath10k_mac_set_sar_specs to ath10k_ops, and this function is called when user space application calls NL80211_CMD_SET_SAR_SPECS. ath10k also registers SAR type, and supported frequency ranges to wiphy so user space can query SAR capabilities. This SAR power limitation is compared to regulatory txpower and selects the minimal one to set when station is connected. Otherwise, it delays until the station is connected. If the station is disconnected, it returns to regulatory txpower. This feature is controlled by hw parameter: dynamic_sar_support.

2020-12-12ath10k: add atomic protection for device recoveryWen Gong
When it has more than one restart_work queued meanwhile, the 2nd restart_work is very easy to break the 1st restart work and lead recovery fail. Add a flag to allow only one restart work running untill device successfully recovered. It already has flag ATH10K_FLAG_CRASH_FLUSH, but it can not use this flag again, because it is clear in ath10k_core_start. The function ieee80211_reconfig(called by ieee80211_restart_work) of mac80211 do many things and drv_start(call to ath10k_core_start) is 1st thing, when drv_start complete, it does not mean restart complete. So it add new flag and clear it in ath10k_reconfig_complete, because it is the last thing called from drv_reconfig_complete of function ieee80211_reconfig, after it, the restart process finished.

2020-08-26ath10k: Add new api to support TID specific configurationTamizh Chelvam
This patch add ops for set_tid_config to support TID specific configuration. Station specific TID configuration will have more priority than vif specific TID configuration. WMI_SERVICE_PEER_TID_CONFIGS_SUPPORT service flag introduced to notify host for TID config support. And RTS_CTS extended tid configuration support advertised through the service flag WMI_10_4_SERVICE_EXT_PEER_TID_CONFIGS_SUPPORT. TID specific noack configuration requires aggregation should be disabled and rate for the data TID packets should be basic rates. So, if the TID already configured with noack policy then driver will ignore the aggregation or TX rate related configuration for the same data TID. In TX rate configuration should be applied with highest preamble configuration(HT rates should not be applied for the station which supports vht rates).

2020-08-15ath10k: correct the array index from mcs index for HT mode for QCA6174Wen Gong
The mcs index of HT mode is 0 to 31, please refer http://mcsindex.com/. Its spatial stream(Nss) number is from 1 to 4, mcs index is 0~7 for Nss=1, 8~15 for Nss=2, 16~23 for Nss=3 and 24~31 is for Nss=4. The mcs is reported from firmware in wmi_tlv_peer_stats_info of event WMI_TLV_PEER_STATS_INFO_EVENTID, its range is from 0~15 for QCA6174 SDIO and PCIe. It is for both Nss=1 and Nss=2, and it has 2 rate table supported_ht_mcs_rate_nss1 and supported_ht_mcs_rate_nss2 in ath10k, they are for Nss=1 and Nss=2, each table has 8 rates. It need to find the matched row number with the mcs index, for example, mcs index is 2, it is <=7, so it is Nss=1, and match row 2 in table of Nss=1. If mcs index is 12, it is >= 8 and <= 15, so it is Nss=2, it match row 4(12-8) in table of Nss=2. If mcs index is >=16, it is for Nss=3/4, it need to add rate table, so it is not support in current ath10k. This patch is to find the row number in rate table of Nss=1 or Nss=2 with the mcs index reported from firmware. This patch only effect the chips which supports_peer_stats_info of its hw_params is true, it is true only for QCA6174 currently.

2020-08-15ath10k: remove return for NL80211_STA_INFO_TX_BITRATEWen Gong
ath10k_sta_statistics is used to report many info to iw wlan0 link, if it return for empty legacy and nss of arsta->txrate, then the other stats after it will not be set. It has 4 bit to set after the return: NL80211_STA_INFO_TX_FAILED NL80211_STA_INFO_RX_BITRATE NL80211_STA_INFO_TX_BITRATE NL80211_STA_INFO_TX_RETRIES This patch not effect the info of above 4 bit for all hardware, reason as below: NL80211_STA_INFO_TX_FAILED is only for htt.disable_tx_comp is true, it is for QCA6174 SDIO. NL80211_STA_INFO_RX_BITRATE and NL80211_STA_INFO_TX_BITRATE are both set in ath10k_mac_sta_get_peer_stats_info, it is only enabled for chips which supports_peer_stats_info is true in hw_params, recently only for QCA6174 SDIO, NL80211_STA_INFO_TX_BITRATE is set again in function ath10k_mac_sta_get_peer_stats_info because the value which parsed from arsta->tx_rate_code and arsta->tx_bitrate_kbps is correct for QCA6174 SDIO and PCIe, and the value arsta->txrate is not correct for QCA6174 SDIO and PCIe, so it need to set again with the correct value. NL80211_STA_INFO_TX_RETRIES is use value of arsta->tx_retries, it is set in ath10k_update_per_peer_tx_stats, which accumulate the retry_pkts in HTT message from firmware, if the chips not support this feature, then it is always 0 after accumulate, then iw wlan0 station dump always show 0 for retry count. If not set NL80211_STA_INFO_TX_RETRIES here, then it is still 0, so the result is same, then set NL80211_STA_INFO_TX_RETRIES has no effect.

2020-06-16ath10k: provide survey info as accumulated dataVenkateswara Naralasetty
It is expected that the returned counters by .get_survey are monotonic increasing. But the data from ath10k gets reset to zero regularly. Channel active/busy time are then showing incorrect values (less than previous or sometimes zero) for the currently active channel during successive survey dump commands. example: $ iw dev wlan0 survey dump Survey data from wlan0 frequency: 5180 MHz [in use] channel active time: 54995 ms channel busy time: 432 ms channel receive time: 0 ms channel transmit time: 59 ms ... $ iw dev wlan0 survey dump Survey data from wlan0 frequency: 5180 MHz [in use] channel active time: 32592 ms channel busy time: 254 ms channel receive time: 0 ms channel transmit time: 0 ms ... The correct way to handle this is to use the non-clearing WMI_BSS_SURVEY_REQ_TYPE_READ wmi_bss_survey_req_type. The firmware will then accumulate the survey data and handle wrap arounds.

2020-06-16ath10k: fix retry packets update in station dumpVenkateswara Naralasetty
When tx status enabled, retry count is updated from tx completion status. which is not working as expected due to firmware limitation where firmware can not provide per MSDU rate statistics from tx completion status. Due to this tx retry count is always 0 in station dump. Fix this issue by updating the retry packet count from per peer statistics. This patch will not break on SDIO devices since, this retry count is already updating from peer statistics for SDIO devices.

2020-05-11ath10k: Remove msdu from idr when management pkt send failsRakesh Pillai
Currently when the sending of any management pkt via wmi command fails, the packet is being unmapped freed in the error handling. But the idr entry added, which is used to track these packet is not getting removed. Hence, during unload, in wmi cleanup, all the entries in IDR are removed and the corresponding buffer is attempted to be freed. This can cause a situation where one packet is attempted to be freed twice. Fix this error by rmeoving the msdu from the idr list when the sending of a management packet over wmi fails.

2020-05-05ath10k: remove the max_sched_scan_reqs valueWen Gong
The struct cfg80211_wowlan of NET_DETECT WoWLAN feature share the same struct cfg80211_sched_scan_request together with scheduled scan request feature, and max_sched_scan_reqs of wiphy is only used for sched scan, and ath10k does not support scheduled scan request feature, so ath10k does not set flag NL80211_FEATURE_SCHED_SCAN_RANDOM_MAC_ADDR, but ath10k set max_sched_scan_reqs of wiphy to a non zero value 1, then function nl80211_add_commands_unsplit of cfg80211 will set it support command NL80211_CMD_START_SCHED_SCAN because max_sched_scan_reqs is a non zero value, but actually ath10k not support it, then it leads a mismatch result for sched scan of cfg80211, then application shill found the mismatch and stop running case of MAC random address scan and then the case fail. After remove max_sched_scan_reqs value, it keeps match for sched scan and case of MAC random address scan pass. Tested with QCA6174 SDIO with firmware WLAN.RMH.4.4.1-00029.

2020-04-28ath10k: add bitrate parse for peer stats infoWen Gong
The rate code and rate kbps report by WMI_TLV_PEER_STATS_INFO_EVENTID from firmware contains all the bitrate info which include OFDM, CCK, HT/VHT, and mac80211 need the struct rate_info which include below parameters: flags: bitflag of flags from &enum rate_info_flags mcs: mcs index if struct describes an HT/VHT/HE rate legacy: bitrate in 100kbit/s for 802.11abg nss: number of streams (VHT & HE only) bw: bandwidth (from &enum rate_info_bw) For OFDM/CCK, its rate kbps indicate the bitrate, for HT/VHT, mac80211 need the above 5 parameters to cacluate the bitrate and show by iw. After parse the bitrate info, iw show the correct rx bitrate: localhost ~ # iw wlan0 link rx bitrate: 234.0 MBit/s VHT-MCS 3 80MHz VHT-NSS 2 rx bitrate: 40.5 MBit/s MCS 2 40MHz rx bitrate: 72.2 MBit/s MCS 7 short GI rx bitrate: 54.0 MBit/s rx bitrate: 48.0 MBit/s Tested with QCA6174 SDIO with firmware WLAN.RMH.4.4.1-00042.

2020-04-28ath10k: add rx bitrate report for SDIOWen Gong
For SDIO chip, its rx indication is struct htt_rx_indication_hl, which does not include the bitrate info as well as PCIe, for PCIe, it use function ath10k_htt_rx_h_rates to parse the bitrate info in struct rx_ppdu_start and then report it to mac80211 via ieee80211_rx_status. SDIO does not have the same info as PCIe, then iw command can not get the rx bitrate by "iw wlan0 station dump". for example, it always show 6.0 MBit/s localhost ~ # iw wlan0 link Connected to 3c:28:6d:96:fd:69 (on wlan0) SSID: kukui_test freq: 5180 RX: 111800 bytes (595 packets) TX: 35419 bytes (202 packets) signal: -41 dBm rx bitrate: 6.0 MBit/s This patch is to send WMI_TLV_REQUEST_PEER_STATS_INFO_CMDID to firmware for ath10k_sta_statistics and save the rx bitrate for WMI event WMI_TLV_PEER_STATS_INFO_EVENTID.

2020-04-27ath10k: add statistics of tx retries and tx failed when tx complete disableWen Gong
When tx complete is disabled, all tx status will be set with status HTT_TX_COMPL_STATE_ACK and indicate to mac80211 by ieee80211_tx_status, then it does not have the statistics for retries and failed packets. count of tx retries and tx failed of command "iw wlan0 station dump" are both 0. If tx complete is not disabled, then firmware report the tx status and ath10k indicate the status to mac80211, then mac80211 save the statistics and command "iw wlan0 station dump" show them. for example: localhost ~ # iw dev wlan0 station dump Station 3c:28:6d:96:fd:69 (on wlan0) inactive time: 5 ms rx bytes: 1325012 rx packets: 6477 tx bytes: 85264 tx packets: 518 tx retries: 0 tx failed: 0 This patch only effect chips with tx complete disabled, e.g. SDIO. with this patch, output of command "iw dev wlan0 station dump": Station c4:04:15:5d:97:22 (on wlan0) inactive time: 608 ms rx bytes: 180366 rx packets: 991 tx bytes: 98765577 tx packets: 64624 tx retries: 14682 tx failed: 47086 Tested with QCA6174 SDIO with firmware WLAN.RMH.4.4.1-00042.

2020-04-27ath10k: enable rx duration report default for wmi tlvWen Gong
When run command "iw dev wlan0 station dump", the rx duration is 0. When firmware indicate WMI_UPDATE_STATS_EVENTID, extended flag of statsis not set by default, so firmware do not report rx duration. one sample: localhost # iw wlan0 station dump Station c4:04:15:5d:97:22 (on wlan0) inactive time: 48 ms rx bytes: 21670 rx packets: 147 tx bytes: 11529 tx packets: 100 tx retries: 88 tx failed: 36 beacon loss: 1 beacon rx: 31 rx drop misc: 47 signal: -72 [-74, -75] dBm signal avg: -71 [-74, -75] dBm beacon signal avg: -71 dBm tx bitrate: 54.0 MBit/s MCS 3 40MHz rx bitrate: 1.0 MBit/s rx duration: 0 us This patch enable firmware's extened flag of stats by setting flag WMI_TLV_STAT_PEER_EXTD of ar->fw_stats_req_mask which is set in ath10k_core_init_firmware_features via WMI_REQUEST_STATS_CMDID. After apply this patch, rx duration show value with the command: Station c4:04:15:5d:97:22 (on wlan0) inactive time: 883 ms rx bytes: 44289 rx packets: 265 tx bytes: 10838 tx packets: 93 tx retries: 899 tx failed: 103 beacon loss: 0 beacon rx: 78 rx drop misc: 46 signal: -71 [-74, -76] dBm signal avg: -70 [-74, -76] dBm beacon signal avg: -70 dBm tx bitrate: 54.0 MBit/s MCS 3 40MHz rx bitrate: 1.0 MBit/s rx duration: 358004 us This patch do not have side effect for all chips, because function ath10k_debug_fw_stats_request is already exported to debugfs "fw_stats" and WMI_REQUEST_STATS_CMDID is safely sent after condition checked by ath10k_peer_stats_enabled in ath10k_sta_statistics.

2020-04-22ath10k: add flush tx packets for SDIO chipWen Gong
When station connected to AP, and run TX traffic such as TCP/UDP, and system enter suspend state, then mac80211 call ath10k_flush with set drop flag, recently it only send wmi peer flush to firmware and firmware will flush all pending TX packets, for PCIe, firmware will indicate the TX packets status to ath10k, and then ath10k indicate to mac80211 TX complete with the status, then all the packets has been flushed at this moment. For SDIO chip, it is different, its TX complete indication is disabled by default, and it has a tx queue in ath10k, and its tx credit control is enabled, total tx credit is 96, when its credit is not sufficient, then the packets will buffered in the tx queue of ath10k, max packets is TARGET_TLV_NUM_MSDU_DESC_HL which is 1024, for SDIO, when mac80211 call ath10k_flush with set drop flag, maybe it have pending packets in tx queue of ath10k, and if it does not have sufficient tx credit, the packets will stay in queue untill tx credit report from firmware, if it is a noisy environment, tx speed is low and the tx credit report from firmware will delay more time, then the num_pending_tx will remain > 0 untill all packets send to firmware. After the 1st ath10k_flush, mac80211 will call the 2nd ath10k_flush without set drop flag immediately, then it will call to ath10k_mac_wait_tx_complete, and it wait untill num_pending_tx become to 0, in noisy environment, it is esay to wait about near 5 seconds, then it cause the suspend take long time. 1st and 2nd callstack of ath10k_flush [ 303.740427] ath10k_sdio mmc1:0001:1: ath10k_flush

2020-02-14mac80211: Fix setting txpower to zeroBen Greear
With multiple VIFS ath10k, and probably others, tries to find the minimum txpower for all vifs and uses that when setting txpower in the firmware. If a second vif is added and starts to scan, it's txpower is not initialized yet and it set to zero. ath10k had a patch to ignore zero values, but then it is impossible to actually set txpower to zero. So, instead initialize the txpower to INT_MIN in mac80211, and let drivers know that means the power has not been set and so should be ignored. This should fix regression in: commit 88407beb1b1462f706a1950a355fd086e1c450b6 Author: Ryan Hsu <ryanhsu@qca.qualcomm.com> Date: Tue Dec 13 14:55:19 2016 -0800 ath10k: fix incorrect txpower set by P2P_DEVICE interface Tested on ath10k 9984 with ath10k-ct firmware.

BTCOEX feature is not supported by all QCA4019 chipsets. Since btcoex enabled by default in firmware, host needs to enable COEX support depends on the hardware. Enabling it by default in unsupported hardware will cause some feature disabled in hardware. This patch will read btcoex_support flag and wlan priority gpio pin number from DT. Depends on the btcoex_support flag value host will expose BTCOEX support and wlan priority gpio pin number to target.

2019-12-13mac80211: Turn AQL into an NL80211_EXT_FEATUREToke Høiland-Jørgensen
Instead of just having an airtime flag in debugfs, turn AQL into a proper NL80211_EXT_FEATURE, so drivers can turn it on when they are ready, and so we also expose the presence of the feature to userspace. This also has the effect of flipping the default, so drivers have to opt in to using AQL instead of getting it by default with TXQs. To keep functionality the same as pre-patch, we set this feature for ath10k (which is where it is needed the most). While we're at it, split out the debugfs interface so AQL gets its own per-station debugfs file instead of using the 'airtime' file. [Johannes:] This effectively disables AQL for iwlwifi, where it fixes a number of issues: * TSO in iwlwifi is causing underflows and associated warnings in AQL * HE (802.11ax) rates aren't reported properly so at HE rates, AQL could never have a valid estimate (it'd use 6 Mbps instead of up to 2400!)

2019-11-29ath10k: set WMI_PEER_AUTHORIZE after a firmware crashWen Gong
After the firmware crashes ath10k recovers via ieee80211_reconfig(), which eventually leads to firmware configuration and including the encryption keys. However, because there is no new auth/assoc and 4-way-handshake, and firmware set the authorize flag after 4-way-handshake, so the authorize flag in firmware is not set in firmware without 4-way-handshake. This will lead to a failure of data transmission after recovery done when using encrypted connections like WPA-PSK. Set authorize flag after installing keys to firmware will fix the issue. This was noticed by testing firmware crashing using simulate_fw_crash debugfs file. Tested with QCA6174 SDIO with firmware WLAN.RMH.4.4.1-00007-QCARMSWP-1.
