This adds new dt entry ext-fem-name, it is used by ath10k driver to select correct timing parameters and configure it in target wifi hardware. The Front End Module(FEM) normally includes tx power amplifier(PA) and rx low noise amplifier(LNA). The default timing parameters like tx end to PA off timing values were fine tuned for internal FEM used in reference design. And these timing values can not be same if ODM modifies hardware design with different external FEM. This DT entry helps to choose correct timing values in driver if different external FEM hardware used.

In qcom,ath10k documentation, ath10k is used as node name in the example of pci based device. Normally, node name should be class of device and not the model name, so fix it to node name "wifi". And remove the property device_type pci since only pci bridges should have this property.

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.

Some hardwares variants (QCA99x0) are limiting msdu deaggregation with some threshold value(default limit in QCA99x0 is 64 msdus), it was introduced to avoid excessive MSDU-deaggregation in error cases. When number of sub frames exceeds the limit, target hardware will send all msdus starting from present msdu in RAW format as a single msdu packet and it will be indicated with error status bit "RX_MSDU_END_INFO0_MSDU_LIMIT_ERR" set in rx descriptor. This msdu frame is a partial raw MSDU and does't have first msdu and ieee80211 header. It caused below warning message. [ 320.151332] ------------[ cut here ]------------ [ 320.155006] WARNING: CPU: 0 PID: 3 at drivers/net/wireless/ath/ath10k/htt_rx.c:1188 In our issue case, MSDU limit error happened due to FCS error and generated this warning message. This fixes the warning by handling the MSDU limit error. If msdu limit error happens, driver adds first MSDU's ieee80211 header and sets A-MSDU present bit in QOS header so that upper layer processes this frame if it is valid or drop it if FCS error set. And removed the warning message, hence partial msdus without first msdu is expected in msdu limit error cases.

Currently in 10.4 FW, all the received 4addr frames are processed for source port learning which is enabled by default. This learning can't be disabled by default in FW since it breaks backward compatibility. Since ath10k uses mac80211 based 4addr mode, source port learning done in 10.4 FW is redundant and also causes issues when 3addr frames are transmitted/received for a 4addr station. One such visible functional impact is when GTK rekey frame from hostapd based AP to 4addr STA is dropped in AP's 10.4 FW. This is since GTK rekey EAPOL frame is 3addr frame on AP interface and STA enabled with 4addr is already allowed for receiving 3addr EAPOL frames. Source port learning implementation in 10.4 FW drops this 3addr GTK rekey frame in AP destinated for 4addr STA causing disassociation and re-association for every GTK rekey session. GTK rekey issue is not seen when learning is disabled in FW. To prevent such issues without breaking backward compatibility, FW advertises new service bit making the source port learning configurable and this learning is being currently disabled during ath10k vdev creation. * Tested HW: QCA9984 * Tested FW: 10.4-3.6.0.1-00004 Signed-off-by: Sathishkumar Muruganandam <murugana@codeaurora.org> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

Mesh path metric needs tx rate information from ieee80211_tx_status() call but in ath10k there is no mechanism to report tx rate information via ieee80211_tx_status(), the tx rate is only accessible via sta_statiscs() op. Per peer tx stats has tx rate info available, Tx rate is available to ath10k driver after every 4 PPDU sent in the air. For each PPDU, ath10k driver updates rate informattion to mac80211 using ieee80211_tx_rate_update(). Per peer txrate information is updated through per peer statistics and is available for QCA9888/QCA9984/QCA4019/QCA998X only Tested on QCA9984 with firmware-5.bin_10.4-3.5.3-00053 Tested on QCA998X with firmware-5.bin_10.2.4-1.0-00036 Signed-off-by: Anilkumar Kolli <akolli@codeaurora.org> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

When processing HTT_T2H_MSG_TYPE_RX_IN_ORD_PADDR_IND, if the length of a msdu is larger than the tailroom of the rx skb, skb_over_panic issue will happen when calling skb_put. In monitor mode, amsdu will be handled in this path, and msdu_len of the first msdu_desc is the length of the entire amsdu, which might be larger than the maximum length of a skb, in such case, it will hit the issue upon. To fix this issue, process msdu list separately for monitor mode. Successfully tested with: QCA6174 (FW version: RM.4.4.1.c2-00057-QCARMSWP-1).

This issue arise in a race condition between ath10k_sta_state() and ath10k_htt_fetch_peer_stats(), explained in below scenario Steps: 1. In ath10k_sta_state(), arsta->tx_stats get deallocated before peer deletion when the station moves from IEEE80211_STA_NONE to IEEE80211_STA_NOTEXIST state. 2. Meanwhile ath10k receive HTT_T2H_MSG_TYPE_PEER_STATS message. In ath10k_htt_fetch_peer_stats(), arsta->tx_stats get accessed after the peer validation check. Since arsta->tx_stats get freed before the peer deletion [1]. ath10k_htt_fetch_peer_stats() ended up in "use after free" situation. Fixed this issue by moving the arsta->tx_stats free handling after the peer deletion. so that ath10k_htt_fetch_peer_stats() will not end up in "use after free" situation.

The following set of NPC registers allow the driver to configure NPC to generate different key value schemes to compare against packet payload in MCAM search. NPC_AF_INTF(0..1)_KEX_CFG NPC_AF_KEX_LDATA(0..1)_FLAGS_CFG NPC_AF_INTF(0..1)_LID(0..7)_LT(0..15)_LD(0..1)_CFG NPC_AF_INTF(0..1)_LDATA(0..1)_FLAGS(0..15)_CFG Currently, the AF driver populates these registers to configure the default values to address the most common use cases such as key generation for channel number + DMAC. The secure firmware stores different configuration value of these registers to enable different NPC use case along with the name for the lookup. Patch loads profile binary from secure firmware over the exiting CGX mailbox interface and apply the profile. AF driver shall fall back to the default configuration in case of any errors. The AF consumer driver can know the selected profile on response to NPC_GET_KEX_CFG mailbox by introducing mkex_pfl_name in the struct npc_get_kex_cfg_rsp.

TL1 is the root node in the scheduling hierarchy and it is a global resource with a limited number. This patch introduces restriction and validation on the allocation of the TL1 nodes for the effective resource sharing across the AF consumers. - Limit TL1 allocation to 2 per lmac. One could be for the normal link and one for IEEE802.3br express link (Express Send DMA). Effectively all the VF's of an RVU PF(lmac) share the two TL1 schqs. - TL1 cannot be freed once allocated. - Allow VF's to only apply default config to TL1 if not already applied. PF's can always overwrite the TL1 config. - Consider NIX_AQ_INSTOP_WRITE while validating txschq when sq.ena is set.
