ath10k: Add peer param map for tlv and non-tlv

2019-09-23T07:27:56Z

The peer param id for PEER_PARAM_USE_FIXED_PWR is different for tlv and non-tlv firmware. This causes incorrect peer param to be set by the driver to the firmware(tlv/non-tlv). Create seperate peer param map for tlv and non-tlv firmware and attach the peer param id based on the firmware type during the init.

ath10k: Check tx_stats before use it

2019-05-07T14:03:47Z

tx_stats will be freed and set to NULL before debugfs_sta node is removed in station disconnetion process. So if read the debugfs_sta node there may be NULL pointer error. Add check for tx_stats before use it to resove this issue. Signed-off-by: Yingying Tang Signed-off-by: Kalle Valo

ath10k: Fix the wrong updation of BW in tx_stats debugfs entry

2019-02-28T08:46:06Z

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.

ath10k: switch to use SPDX license identifiers

2019-02-20T08:33:00Z

Use SPDX identifiers everywhere in ath10k. Makefile was incorrectly marked in commit b24413180f56 ("License cleanup: add SPDX GPL-2.0 license identifier to files with no license"), fix that as well. Signed-off-by: Kalle Valo

ath10k: change 'unsigned long int' to 'unsigned long'

ath10k: fix peer stats null pointer dereference

2018-12-20T17:08:35Z

There was a race condition in SMP that an ath10k_peer was created but its member sta was null. Following are procedures of ath10k_peer creation and member sta access in peer statistics path. 1. Peer creation: ath10k_peer_create() =>ath10k_wmi_peer_create() =>ath10k_wait_for_peer_created() ... # another kernel path, RX from firmware ath10k_htt_t2h_msg_handler() =>ath10k_peer_map_event() =>wake_up() # ar->peer_map[id] = peer //add peer to map #wake up original path from waiting ... # peer->sta = sta //sta assignment 2. RX path of statistics ath10k_htt_t2h_msg_handler() =>ath10k_update_per_peer_tx_stats() =>ath10k_htt_fetch_peer_stats() # peer->sta //sta accessing Any access of peer->sta after peer was added to peer_map but before sta was assigned could cause a null pointer issue. And because these two steps are asynchronous, no proper lock can protect them. So both peer and sta need to be checked before access.

ath10k: add debugfs support to get power save state change of STA

2018-10-01T14:02:08Z

This patch helps to get the power save state change of each peer connected to the AP. With WMI_10_4_PEER_STA_PS_STATECHG_EVENTID event, ps state of each peer is reported to user space via debugfs. Use the below command to get the ps state of each sta: cat /sys/kernel/debug/ieee80211/phyX/netdev::wlanX/stations/ XX:XX:XX:XX:XX:XX/peer_ps_state If STA is in power save state, we get the peer_ps_state value as 1. if STA is not in power save state, we get the peer_ps_state value as 0. If ps_state event is disabled, we get the peer_ps_state value as 2. We can enable/disable the ps_state events using the debugfs flag "ps_state_enable" echo Y > /sys/kernel/debug/ieee80211/phyX/ath10k/ps_state_enable Y = 1 to enable and Y = 0 to disable Tested in QCA4019 with firmware ver 10.4-3.2.1.1-00011 Signed-off-by: Maharaja Kennadyrajan Signed-off-by: Kalle Valo
