2020-11-10mwifiex: fix mwifiex_shutdown_sw() causing sw reset failureTsuchiya Yuto1-0/+2
When a PCIe function level reset (FLR) is performed but without fw reset for some reasons (e.g., on Microsoft Surface devices, fw reset requires other quirks), it fails to reset wifi properly. You can trigger the issue on such devices via debugfs entry for reset: $ echo 1 | sudo tee /sys/kernel/debug/mwifiex/mlan0/reset and the resulting dmesg log: [ 45.740508] mwifiex_pcie 0000:03:00.0: Resetting per request [ 45.742937] mwifiex_pcie 0000:03:00.0: info: successfully disconnected from [BSSID]: reason code 3 [ 45.744666] mwifiex_pcie 0000:03:00.0: info: shutdown mwifiex...

is_any_client_connect_to_ap() is using in_interrupt() to determine whether it should acquire the lock prior accessing the list. The usage of in_interrupt() in drivers is phased out and Linus clearly requested that code which changes behaviour depending on context should either be separated or the context be conveyed in an argument passed by the caller, which usually knows the context. The function is called from: - halbtc_get() - halbtc_get() halbtc_get_wifi_link_status() - halbtc_display_dbg_msg() halbtc_display_wifi_status() halbtc_get_wifi_link_status() All top level callers are part of the btc_coexist callback inferface and are never invoked from a context which can hold the lock already. The contexts which hold the lock are either protecting list add/del operations or list walks which never call into any of the btc_coexist interfaces. In fact the conditional is outright dangerous because if this function would be invoked from a BH disabled context the check would avoid taking the lock while on another CPU the list could be manipulated under the lock. Remove the in_interrupt() check and always acquire the lock. To simplify the code further use list_empty() instead of walking the list and counting the entries just to check the count for > 0 at the end.

2020-11-07rtw88: sync the power state between driver and firmwareChin-Yen Lee1-39/+30
In current flow, driver issues power requests to firmware for entering or leaving deep power mode. But driver does not wait for an ack from firmware via reading CPWM register when driver requests to enter deep power mode. The behavior will lead to unsynchronized state between firmware and driver. Furthermore, consecutive same power requests may confuse firmware and leads to unexpected value of CPWM register. This patch ensures that the power request will wait for an ack from firmware and only send one power request each time.

2020-11-07rtw88: coex: separate BLE HID profile from BLE profileChing-Te Ku5-9/+42
BT firmware will report BLE-HID and BLE-RCU in different profile. We can distinguish the two profile from BT info now. Add the coexistence for BLE-HID coexistence, it can make BLE HID work more smoothly. BLE-HID need to Tx/Rx packet more frequently to respond user operation, but RCU doesn't. In the case of RCU coexistence, it will make Wi-Fi have a higher priority to earn more Wi-Fi throughput. If BLE-HID go for the same case, it will make user feel mouse is lagging.

2020-11-07rtlwifi: Fix non-canonical address access issuesWeitaoWangoc1-1/+0
During realtek USB wireless NIC initialization, it's unexpected disconnection will cause urb sumbmit fail. On the one hand, _rtl_usb_cleanup_rx will be called to clean up rx stuff, especially for rtl_wq. On the other hand, disconnection will cause rtl_usb_disconnect and _rtl_usb_cleanup_rx to be called. So, rtl_wq will be flush/destroy twice, which will cause non-canonical address 0xdead000000000122 access and general protection fault. Fixed this issue by remove _rtl_usb_cleanup_rx when urb sumbmit fail.

2020-11-07rsi: Fix TX EAPOL packet handling against iwlwifi APMarek Vasut1-1/+2
In case RSI9116 SDIO WiFi operates in STA mode against Intel 9260 in AP mode, the association fails. The former is using wpa_supplicant during association, the later is set up using hostapd: iwl$ cat hostapd.conf interface=wlp1s0 ssid=test country_code=DE hw_mode=g channel=1 wpa=2 wpa_passphrase=test wpa_key_mgmt=WPA-PSK iwl$ hostapd -d hostapd.conf rsi$ wpa_supplicant -i wlan0 -c <(wpa_passphrase test test) The problem is that the TX EAPOL data descriptor RSI_DESC_REQUIRE_CFM_TO_HOST flag and extended descriptor EAPOL4_CONFIRM frame type are not set in case the AP is iwlwifi, because in that case the TX EAPOL packet is 2 bytes shorter. The downstream vendor driver has this change in place already [1], however there is no explanation for it, neither is there any commit history from which such explanation could be obtained.
