This patch essentially adds two callback in ath10k_pci, one for doing soft reset and the other for hard reset. By using callbacks we can get rid of those hw revision checks in ath10k_pci_safe_chip_reset() and ath10k_pci_chip_reset(). As such this patch does not fix any issue.

This scenario happens in QCA4019 when we start the AP via hostapd in background and start it once again in the background without killing the previous instance! This happens intermittently when we start / stop hostapd in a while loop (incase the hostapd is not properly killed). This results in mac80211 chancontext to be unassigned, while the self peer continuous receive packets in target operating channel. This results in lot of call traces in the rx path. Make this as a WARN_ON_ONCE to avoid flooding the console which result in rebooting low memory systems, while still reporting the warning once that we are receiving packets in target operating channel and to indicate that something is happening which is not the expected result.

Also, macros which can be used to extract flush_valid and release_valid bits have to be left shifted one bit less because these information follow the tid right after. This patch does not really fix anything functionally because these macros are not used currently.

Fix this by aborting the P2P search in wil_cfg80211_stop_p2p_device and preventing P2P search from being started on a stopped P2P device. Note, the fix does not cover the case where a regular scan is started on the P2P device. It will be completed in the future when support is added for aborting a scan operation.

Now when the PCI card is unplugged from the device the PCI controller seems to generate a spurious interrupt after some time which was as treated a firmware crash and resulting in the below race condition (and eventually crashing the system) ath10k_core_unregister -> ath10k_core_free_board_files ...... device unplug spurious interrupt ......... ath10k_pci_taklet -> ath10k_pci_fw_crashed_dump ...etc Clearly even after the firmware board files related data structure is freed up we are getting a spurious interrupt from PCI with 0xfffffff in the 'FW_INDICATOR_ADDRESS' resulting in scheduling of the pci tasklet and doing a crash dump, printing f/w board related info resulting in the below crash. Fix this by detecting this spurious interrupt in ath10k PCI irq handler itself and return IRQ_NONE. Thanks to Michal Kazior for helping us conclude the most appropriate fix.

All the others should be updated by mac80211. During ACS scan we wouldn't have a valid channel context assigned from mac80211 ('ar->rx_channel'), and also relying on ('ar->scan_channel') is not helpful (it becomes NULL when it goes to BSS channel and also when the scan event is completed). In short we cannot always rely on these two channel tracking variables. 'Target Operating Channel' (ar->tgt_oper_chan) seems to keep track of the current operating even while we are doing ACS scan and etc. Hence remove this un-necessary warning message and continue with target_operating channel. At the worst case scenario when the target operating channel is invalid (NULL) we already have an ath10k warning message to notify we really don't have a proper channel configured in rx to update the rx status("no channel configured; ignoring frame(s)!")

If the measurement mode is set to passive or active, it requires actually performing a scan (passive or active, accordingly), and reporting the time that the scan was started and the time each beacon/probe was received (both in terms of TSF of the BSS of the requesting AP). If the request mode is table, this information is optional. In addition, the radio measurement request specifies the channel dwell time for the measurement. In order to use scan for beacon report when the mode is active or passive, add a parameter to scan request that specifies the channel dwell time, and add scan start time and beacon received time to scan results information. Supporting beacon report is required for Multi Band Operation (MBO).

But from experiments with 10.4 based solutions, it is observed that pktlog event for ATH_PKTLOG_TYPE_TX_MSDU_ID is coming through HTT pktlog event. Currently, we always parse with 10.2 pktlog header which will lead to pktlog decoding issues (payload length mismatch exceptions) For trace points, it is required to provide only the payload size. So fixing this by simplifying the payload size calculation without the use of ath10k pktlog headers. While there, remove the unused ath10k pktlog headers.

It could for example happen that an AP interface in beacon slot 0 was removed leaving an IBSS station in one of the other slots. When this happens the driver never sends out the beacon as it only tries to send a beacon from slot 0. Appart from that the tracking of required changes to the beacon config is relatively complicated and prone to errors. The approach taken here is to solve reconfiguration issues is to reconfigure the beacons when any interface changes. This means that the complexity of deciding whether an interface change may modify the beacon configuration is gone. It also means that the beacon config will be reliably updated when an interface is removed. The issue that a single non-AP interface might not be in beacon slot 0 and wouldn't be send out is solved by moving it into the first slot. The TSF value in hardware is adjusted accordingly so that the timestamp of the beacons stay consistent.

When enabling WLAN tethering, a new AP is visible and a STA could connect to it. When the STA tries to authenticate to the newly created AP, the WPA authentication mechanism is stuck in the 1/4 msg of 4-Way Handshake. In ath6kl_rx(), the ath6kl_find_sta() function is looking for the h_source field of the Ethernet frame header received by the STA. The datap pointer that points to the Ethernet frame header is incorrect, and was pointing at the wrong offset in the buffer. This commit adds a pad_before_data_start offset to set the datap pointer to the Ethernet frame header. datap->h_source parameter is now really pointing to the source ethernet address and the authentication process can continue.
