2024-02-02wifi: ath12k: Read board id to support split-PHY QCN9274Ganesh Babu Jothiram
QCN9274 can support single-PHY or split-PHY architecture. Currently, only the single-PHY architecture is supported in ath12k. The split-PHY QCN9274 requires different AMSS firmware binary "amss_dualmac.bin". Hence, add support to read board id from OTP. Based on board id decide whether single-mac / dual-mac firmware needs to be downloaded to the target. Also, update HW param max_radios to support split-PHY in QCN9274. Also, add new Firmware IE for firmware_N.bin "ATH11K_FW_IE_AMSS_DUALMAC_IMAGE" to support dualmac QCN9274.

2024-02-02wifi: ath12k: fix PCI read and writeP Praneesh
Currently, PCI read is failing for the registers belonging to SECURITY_CONTROL_WLAN registers. These registers read is required to read the board-id to identify the dual-mac QCN9274 hardware. The failure is because, for these registers (SECURITY_CONTROL_WLAN) offset, ath12k_pci_get_window_start() returns window_start as 0. Due to this PCI read is done without PCI select window and with window_start offset as 0. Hence, fix PCI read and write by doing PCI select window and by using the correct window_start offset - WINDOW_START for SECURITY_CONTROL_WLAN registers.

2024-02-02wifi: ath12k: add MAC id support in WBM error pathKarthikeyan Periyasamy
When more than one pdev is supported in the chip/SoC, the packet belonging to second pdev is given to first pdev due to not identifying the MAC id in the WBM error path. So ping fails. In WBM error path, src link id information not available in the descriptor. So get this information from the msdu_end 64bit tag. It is necessary to get the src link id to identify the MAC id in the given chip. Then only we can pass the skb to the corresponding pdev. The msdu_end 64bit tag is available only if compact Rx TLVs descriptors are used. Thus, src link id is fetched correctly in WBM error path when compact descriptors are in use.

2024-02-02wifi: ath12k: subscribe required word mask from rx tlvKarthikeyan Kathirvel
Most of the RX descriptors fields are currently not used in the ath12k driver. Hence add support to selectively subscribe to the required quad words (64 bits) within msdu_end and mpdu_start of rx_desc. Add compact rx_desc structures and configure the bit mask for Rx TLVs (msdu_end, mpdu_start, mpdu_end) via registers. With these registers SW can configure to DMA the partial TLV struct to Rx buffer. Each TLV type has its own register to configure the mask value. The mask value configured in register will indicate if a particular QWORD has to be written to rx buffer or not i.e., if Nth bit is enabled in the mask Nth QWORD will be written and it will not be written if the bit is disabled in mask. While 0th bit indicates whether TLV tag will be written or not. Advantages of Qword subscription of TLVs - Avoid multiple cache-line misses as the all the required fields of the TLV are within 128 bytes. - Memory optimization as TLVs + DATA + SHINFO can fit in 2k buffer even for 64 bit kernel.

2024-02-02wifi: ath12k: remove hal_desc_sz from hw paramsRaj Kumar Bhagat
With word mask subscription support, the rx_desc structure will change. The fields in this structure rx_desc will be reduced to only the required fields. To make word mask subscription changes compatible with the older firmware version (firmware that does not support word mask subscription), two different structures of rx_desc will be required for the same hardware. The hardware param hal_desc_sz value cannot be constant for the same hardware. It depends on the size of rx_desc structure which may change based on firmware capability to support word mask subscription. Hence, remove hal_desc_sz from hardware param and add hal_rx_ops to get the size of rx_desc in run time.

To make word mask subscription changes compatible with the older firmware version (firmware that does not support word mask subscription), two different structures of rx_desc will be required for the same hardware. Most of the hal_ops are directly related to rx_desc. Hence, split hal_ops into operations that are independent of rx_desc (hal_ops) and the operations that are directly dependent on rx_desc (hal_rx_ops). These hal_rx_ops depend on both hardware and firmware hence move them out of hw_params.

2024-02-02wifi: ath12k: fix firmware assert during insmod in memory segment modeAaradhana Sahu
In segment memory mode, firmware allocates memory segments of size 2 MB. This 2 MB memory is used by firmware for the number of peers. This number of peer is sent from host to firmware during WMI init command. For single-phy the number of peers sent is TARGET_NUM_PEERS_SINGLE = 529 (512 + 17). While for split-phy number of peers sent to firmware is TARGET_NUM_PEERS_DBS = 2 *(512 + 17) = 1058. With this 1058 number of peers firmware is unable to allocate memory in 2 MB segment and firmware crash is observed. Hence, fix this firmware crash by reducing the number of stations TARGET_NUM_STATIONS for split-phy.

2024-02-02wifi: ath12k: Add logic to write QRTR node id to scratchP Praneesh
Currently only one MHI device is registered successfully on platform having two or more identical MHI devices. This is beacuse QMI service runs with identical QRTR node ID. And, qrtr-lookup cannot register more than one QMI service with identical node ID. Hence, generate a unique QRTR instance ID from PCIe domain number and bus number. QMI allows node id to be written on scratch register. Add logic to write QRTR node id to the register. It is available for firmware to uniquely identify an instance.

2024-02-02wifi: ath12k: fix fetching MCBC flag for QCN9274Raj Kumar Bhagat
In QCN9274, RX packet's multicast and broadcast(MCBC) flag is fetched from RX descriptor's msdu_end info5 member but it is not correct for QCN9274. Due to this with encryption, ARP request packet is wrongly marked as MCBC packet and it is sent to mac80211 without setting RX_FLAG_PN_VALIDATED & RX_FLAG_DECRYPTED flag. This results in packet getting dropped in mac80211. Hence ping initiated from station to AP fails. Fix this by fetching correct MCBC flag in case of QCN9274. For QC9274 MCBC flag should be fetched from RX descriptor's mpdu_start info6 member.

Firmware IE containers can dynamically provide various information what firmware supports. Also it can embed more than one image so updating firmware is easy, user just needs to update one file in /lib/firmware/. The firmware API 2 or higher will use the IE container format, the current API 1 will not use the new format but it still is supported for some time. Firmware API 2 files are named as firmware-2.bin (which contains both amss.bin and m3.bin images) and API 1 files are amss.bin and m3.bin. Currently ath12k PCI driver provides firmware binary (amss.bin) path to MHI driver, MHI driver reads firmware from filesystem and boots it. Add provision to read firmware files from ath12k driver and provide the amss.bin firmware data and size to MHI using a pointer.

WMI_PEER_ASSOC_CMDID Currently when connecting to an AP with 11AX-HE phy mode, host sends WMI_VDEV_PARAM_SET_HEMU_MODE parameter to firmware after WMI_PEER_ASSOC_CMDID command. This results in TXBF not working, because firmware calculates TXBF values while handling WMI_PEER_ASSOC_CMDID, however at that time WMI_VDEV_PARAM_SET_HEMU_MODE has not been sent yet.

2024-02-02wifi: ath9k: delay all of ath9k_wmi_event_tasklet() until init is completeToke Høiland-Jørgensen
The ath9k_wmi_event_tasklet() used in ath9k_htc assumes that all the data structures have been fully initialised by the time it runs. However, because of the order in which things are initialised, this is not guaranteed to be the case, because the device is exposed to the USB subsystem before the ath9k driver initialisation is completed. We already committed a partial fix for this in commit: 8b3046abc99e ("ath9k_htc: fix NULL pointer dereference at ath9k_htc_tx_get_packet()") However, that commit only aborted the WMI_TXSTATUS_EVENTID command in the event tasklet, pairing it with an "initialisation complete" bit in the TX struct. It seems syzbot managed to trigger the race for one of the other commands as well, so let's just move the existing synchronisation bit to cover the whole tasklet (setting it at the end of ath9k_htc_probe_device() instead of inside ath9k_tx_init()).

2024-01-26Revert "nl80211/cfg80211: Specify band specific min RSSI thresholds with ↵Jeff Johnson
sched scan" This *mostly* reverts commit 1e1b11b6a111 ("nl80211/cfg80211: Specify band specific min RSSI thresholds with sched scan"). During the review of a new patch [1] it was observed that the functionality being modified was not actually being used by any in-tree driver. Further research determined that the functionality was originally introduced to support a new Android interface, but that interface was subsequently abandoned. Since the functionality has apparently never been used, remove it. However, to mantain the sanctity of the UABI, keep the nl80211.h assignments, but clearly mark them as obsolete.

2024-01-26wifi: iwlwifi: add support for a wiphy_work rx handlerMiri Korenblit
The wiphy_work infra ensures that the entire worker will run with the wiphy mutex. It is useful to have RX handlers running as a wiphy_work, when we don't want the handler to run in parallel with mac80211 work (to avoid races). For example - BT notification can disable eSR starting from the next patch. In ieee80211_set_active_links we first check that eSR is allowed, (drv_can_activate_links) and then activate it. If the BT notif was received after drv_can_activate_links (which returned true), and before the activation - eSR will be activated when it shouldn't. If BT notif is handled with the wiphy mutex, it can't run in parallel to ieee80211_set_active_links, which also holds that mutex. Add the necessary infrastructure here, for use in the next commit.

2024-01-26wifi: cfg80211: add support for SPP A-MSDUsJohannes Berg
Add SPP (signaling and payload protected) AMSDU support. Since userspace has to build the RSNX element, add an extended feature flag to indicate that this is supported. In order to avoid downgrade/mismatch attacks, add a flag to the assoc command on the station side, so that we can be sure that the value of the flag comes from the same RSNX element that will be validated by the supplicant against the 4-way-handshake. If we just pulled the data out of a beacon/probe response, we could theoretically look an RSNX element from a different frame, with a different value for this flag, than the supplicant is using to validate in the 4-way-handshake. Note that this patch is only geared towards software crypto implementations or hardware ones that can perfectly implement SPP A-MSDUs, i.e. are able to switch the AAD construction on the fly for each TX/RX frame. For more limited hardware implementations, more capability advertisement would be required, e.g. if the hardware has no way to switch this on the fly but has only a global configuration that must apply to all stations. The driver could of course *reject* mismatches, but the supplicant must know so it can do things like not negotiating SPP A-MSDUs on a T-DLS link when connected to an AP that doesn't support it, or similar.
