Currently, rx_duration for each peer is not getting populated in fw_stats debugfs entry for WCN3990. WCN3990 firmware sends rx duration for each peer as part of peer_extd_stats in WMI_UPDATE_STATS_EVENT. To enable peer_extd_stats, firmware expects host to send fw_stats_req_mask with flag WMI_TLV_PEER_STATS_EXTD set in WMI_REQUEST_STATS_CMD. Send fw_stats_req_mask with flag WMI_TLV_PEER_STATS_EXTD set in WMI_REQUEST_STATS_CMD and parse the peer_extd_stats in WMI_UPDATE_STATS_EVENT to populate the rx_duration of each peer in fw_stats debugfs entry. Currently the driver handles 32-bit rx_duration, but the rx_duration for WCN3990 can be upto 63 bit. The firmware sends rx_duration split into two 32-bit fields, with the upper 32-bits being valid only if its MSB is set. This change handles the 63-bit rx_duration obtained from WCN3990 and maintain the backward compatibility.

ht_idx (ht rate index) and idx (rate table index) are calculated based on mcs index. This mcs index used in the above calculation should be 0-9 for getting the correct ht_idx and idx. Currently the mcs index used for the above calculations is mcs index which can be 0-31 (in case of HT), leading to incorrect rate index and ht index values. Fix the issue by obtaining mcs value from the ratecode reported by firmware and use it for calculating ht_idx and idx (rate-table index).

Currently, the bandwidth is updated wrongly in BW table in tx_stats debugfs per sta as there is difference in number of bandwidth type in mac80211 and driver stats table. This leads to bandwidth getting updated at wrong index in bandwidth table in tx_stats. Fix this index mismatch between mac80211 and driver stats table (BW table) by making the number of bandwidth type in driver compatible with mac80211.

Since ath9k reports airtime usage directly using the ieee80211_report_airtime() callback, it shouldn't also report it using the tx_time in status. Make sure the field is zeroed before TX status is reported to avoid spurious airtime being accounted by bits being left over from earlier uses of the cb.

The length of wmi tlv command for management tx send is calculated incorrectly in case of protected management frames as there is addition of IEEE80211_CCMP_MIC_LEN twice. This leads to improper behaviour of firmware as the wmi tlv mgmt tx send command for protected mgmt frames is formed wrongly. Fix the length calculation of wmi tlv command for mgmt tx send in case of protected management frames by adding the IEEE80211_CCMP_MIC_LEN only once.

The SDIO firmware does not provide RSSI value to the host, it's only set to zero. In that case don't report the value to mac80211. One risk here is that value zero might be a valid value with other firmware, currently there's no way to detect that. Without the fix, the rssi value indicated by iw changes between the actual value and -95. Tested with QCA6174 SDIO with firmware WLAN.RMH.4.4.1-00005-QCARMSWP-1. Co-developed-by:

This is a theoretical fix, the issue is found in code review. When adding the host memory chunks into wmi-tlv init command, there is no separate tlv header for each host memory chunk in the struct array, which breaches the convention between host and firmware, will result in mismatch between the two. To fix this issue, add separate tlv headers for the host memory chunks in wmi-tlv init command. Signed-off-by:

When the driver receives the tx completion of the descriptor over ce, it clears the nbytes configured for that particular descriptor. WCN3990 uses ce descriptors with 64-bit address. Currently during handling the tx completion of the descriptors, the nbytes are accessed from the descriptors using ce_desc for 32-bit targets. This will lead to clearing of memory at incorrect offset if DMA MASK is set to greater than 32 bits. Attach different ce tx copy completed handler for targets using address above 32-bit address.

The patch enables returning 'type' in msghdr for records that are retrieved with MSG_PEEK in recvmsg. Further it prevents records peeked from socket from getting clubbed with any other record of different type when records are subsequently dequeued from strparser. For each record, we now retain its type in sk_buff's control buffer cb[]. Inside control buffer, record's full length and offset are already stored by strparser in 'struct strp_msg'. We store record type after 'struct strp_msg' inside 'struct tls_msg'. For tls1.2, the type is stored just after record dequeue. For tls1.3, the type is stored after record has been decrypted. Inside process_rx_list(), before processing a non-data record, we check that we must be able to return back the record type to the user application. If not, the decrypted records in tls context's rx_list is left there without consuming any data. Fixes: 692d7b5d ("tls: Fix recvmsg() to be able to peek across multiple records") Signed-off-by:

Presently the hns reset_type for the roce errors is set in the hclge_log_and_clear_rocee_ras_error function. This function is also called to detect and clear roce errors while enabling the rdma error interrupts. However there is no hns reset requested for this case. This can cause issue of wrong reset_type used with subsequent hns reset as the reset_type set in the above case was not cleared.
