2023-09-28wifi: ath12k: add support for hardware rfkill for WCN7850Lingbo Kong
When hardware rfkill is enabled in the firmware, it will report the capability using WMI_SYS_CAP_INFO_RFKILL bit in the WMI_SERVICE_READY event to the host. Currently ath12k does not process this service capability. In order to support this, update ath12k to check if the capability is enabled, if so, send the GPIO information to firmware. When the firmware detects hardware rfkill is enabled by the user, it will report it using WMI_RFKILL_STATE_CHANGE_EVENTID. When ath12k receive the event, it will set the value of rfkill_radio_on based on whether radio_state is equal to WMI_RFKILL_RADIO_STATE_ON, then send WMI_PDEV_PARAM_RFKILL_ENABLE to firmware.

2023-09-21wifi: ath12k: fix possible out-of-bound write in ath12k_wmi_ext_hal_reg_caps()Baochen Qiang
reg_cap.phy_id is extracted from WMI event and could be an unexpected value in case some errors happen. As a result out-of-bound write may occur to soc->hal_reg_cap. Fix it by validating reg_cap.phy_id before using it. This is found during code review. Compile tested only.

2023-08-09wifi: ath12k: Fix buffer overflow when scanning with extraieWen Gong
If cfg80211 is providing extraie's for a scanning process then ath12k will copy that over to the firmware. The extraie.len is a 32 bit value in struct element_info and describes the amount of bytes for the vendor information elements. The problem is the allocation of the buffer. It has to align the TLV sections by 4 bytes. But the code was using an u8 to store the newly calculated length of this section (with alignment). And the new calculated length was then used to allocate the skbuff. But the actual code to copy in the data is using the extraie.len and not the calculated "aligned" length. The length of extraie with IEEE80211_HW_SINGLE_SCAN_ON_ALL_BANDS enabled was 264 bytes during tests with a wifi card. But it only allocated 8 bytes (264 bytes % 256) for it. As consequence, the code to memcpy the extraie into the skb was then just overwriting data after skb->end. Things like shinfo were therefore corrupted. This could usually be seen by a crash in skb_zcopy_clear which tried to call a ubuf_info callback (using a bogus address).

2023-08-03wifi: ath12k: avoid deadlock by change ieee80211_queue_work for regd_update_workWen Gong
Deadlock is easily happened while shutdown wlan interface such as run "ifconfig wlan0 down". The reason is because when ar->regd_update_work is ran, it will call wiphy_lock(ar->hw->wiphy) in function ath12k_regd_update() which is running in workqueue of ieee80211_local queued by ieee80211_queue_work(). Another thread from "ifconfig wlan0 down" will also accuqire the lock by wiphy_lock(sdata->local->hw.wiphy) in function ieee80211_stop(), and then it call ieee80211_stop_device() to flush_workqueue(local->workqueue), this will wait the workqueue of ieee80211_local finished. Then deadlock will happen easily if the two thread run meanwhile.

2023-08-03wifi: ath12k: add handler for scan event WMI_SCAN_EVENT_DEQUEUEDWen Gong
When wlan interface is up, and 11d scan is sent to the firmware, then firmware needs to spend couple of seconds to complete the 11d scan. If normal scan from user space arrives to ath12k at this moment, then the normal scan request is also sent to the firmware, but the scan started event will be reported to ath12k until the 11d scan complete. When timed out for the scan started in ath12k, ath12k stops the normal scan and the firmware reports WMI_SCAN_EVENT_DEQUEUED to ath12k for the normal scan. ath12k has no handler for the event and then timed out for the scan completed in ath12k_scan_stop(), and ath12k prints the following error message. [ 1491.604750] ath12k_pci 0000:02:00.0: failed to receive scan abort comple: timed out [ 1491.604756] ath12k_pci 0000:02:00.0: failed to stop scan: -110 [ 1491.604758] ath12k_pci 0000:02:00.0: failed to start hw scan: -110 Add a handler for WMI_SCAN_EVENT_DEQUEUED and then complete the scan to get rid of the above error message.

2023-08-02wifi: ath12k: avoid array overflow of hw mode for preferred_hw_modeWen Gong
Currently ath12k define WMI_HOST_HW_MODE_DBS_OR_SBS=5 as max hw mode for enum wmi_host_hw_mode_config_type, it is also same for the array ath12k_hw_mode_pri_map. When tested with new version firmware/board data which support new hw mode eMLSR mode with hw mode value 8, it leads overflow usage for array ath12k_hw_mode_pri_map in function ath12k_wmi_hw_mode_caps(), and then lead preferred_hw_mode changed to 8, and finally function ath12k_pull_mac_phy_cap_svc_ready_ext() select the capability of hw mode 8, but the capability of eMLSR mode report from firmware does not support 2.4 GHz band for WCN7850, so finally 2.4 GHz band is disabled. Skip the hw mode which exceeds WMI_HOST_HW_MODE_MAX in function ath12k_wmi_hw_mode_caps() helps to avoid array overflow, then the 2.4 GHz band will not be disabled. This is to keep compatibility with newer version firmware/board data files, this change is still needed after ath12k add eMLSR hw mode 8 in array ath12k_hw_mode_pri_map and enum wmi_host_hw_mode_config_type, because more hw mode maybe added in next firmware/board data version e.g hw mode 9, then it will also lead new array overflow without this change.

2023-05-26wifi: ath12k: Add support to parse new WMI event for 6 GHz regulatoryP Praneesh
In order to support different power levels of 6 GHz AP and client, new WMI event for regulatory (WMI_REG_CHAN_LIST_CC_EXT_EVENTID) has been added in firmware to provide new parameters required for 6 GHz regulatory rules. Firmware advertises its capability of handling new event in WMI service ready event. Based on that, host needs to set host_service_flags in WMI init command to indicate that host supports processing of this WMI event. Based on advertised host capability, firmware sends event WMI_REG_CHAN_LIST_CC_EXT_EVENTID. This new event contains 2G/5G/6G reg rules with additional power value fields for 6GHz and regd is built accordingly.

2023-03-24wifi: ath12k: incorrect channel survey dumpHarshitha Prem
When underlying hardware supports more than one band, then wiphy is aware of all the frequency bands present. Example, say wiphy0 is aware of 2 GHz, 5 GHz and 6 GHz band information. Hence, when an virtual AP interface is brought up in auto channel selection on each band. Survey is initiated from the userspace application for all the virtual AP interfaces simultaneously. For survey dump collection, freq_to_idx() api is used to map the index of particular frequency to populate its survey. When the dump was collected, the index fetched was incorrect. Example, in case of multi-hardware, the index of channel 36 was reported as 14, because wiphy0 had index 0-13 for 2 GHz channels, instead of 0 for that ar which resulted in invalid survey sent to userspace application. The incorrect index was because of the mapping did not consider whether the freq band is present in its radio structure (ar) or not. To handle this, the freq_to_idx() api should map index for the particular band in the ar structure.

2022-11-29wifi: ath12k: driver for Qualcomm Wi-Fi 7 devicesKalle Valo
ath12k is a new mac80211 driver for Qualcomm Wi-Fi 7 devices, first supporting QCN9274 and WCN7850 PCI devices. QCN9274 supports both AP and station; WCN7850 supports only station mode. Monitor mode is not (yet) supported. Only PCI bus devices are supported. ath12k is forked from an earlier version of ath11k. It was simpler to have a "clean start" for the new generation and not try to share the code with ath11k. This makes maintenance easier and avoids major changes in ath11k, which would have significantly increased the risk of regressions in existing setups. ath12k uses le32 and cpu_to_le32() macros to handle endian conversions, instead of using the firmware byte swap feature utilized by ath11k. There is only one kernel module, named ath12k.ko. Currently ath12k only supports HE mode (IEEE 802.11ax) or older, but work is ongoing to add EHT mode (IEEE 802.11be) support. The size of the driver is ~41 kLOC and 45 files. To make the review easier, this initial version of ath12k does not support Device Tree, debugfs or any other extra features. Those will be added later, after ath12k is accepted to upstream. The driver is build tested by Intel's kernel test robot with both GCC and Clang. Sparse reports no warnings. The driver is mostly free of checkpatch warnings, albeit few of the warnings are omitted on purpose, list of them here: https://github.com/qca/qca-swiss-army-knife/blob/master/tools/scripts/ath12k/ath12k-check#L52 The driver has had multiple authors who are listed in alphabetical order below.
