* BACKPORT: cfg80211: remove enum ieee80211_bandJohannes Berg2020-02-02
| | | | | | | | | | | | | | This enum is already perfectly aliased to enum nl80211_band, and the only reason for it is that we get IEEE80211_NUM_BANDS out of it. There's no really good reason to not declare the number of bands in nl80211 though, so do that and remove the cfg80211 one.

* wil6210: fix length check in __wmi_sendLior David2017-11-03
| | | | | | | | | | | | The current length check: sizeof(cmd) + len > r->entry_size will allow very large values of len (> U16_MAX - sizeof(cmd)) and can cause a buffer overflow. Fix the check to cover this case. In addition, ensure the mailbox entry_size is not too small, since this can also bypass the above check.

* wil6210: add support for PCIe D3hot in system suspendMaya Erez2017-05-15
| | | | | | | | | | | | | In order to preserve the connection in suspend/resume flow, wil6210 host allows going to PCIe D3hot state in suspend, instead of performing a full wil6210 device reset. This requires the platform ability to initiate wakeup in case of RX data. To check that, a new platform API is added. In addition, add cfg80211 suspend/resume callbacks implementation.

* wil6210: support 8KB RX buffersLior David2017-05-04
| | | | | | | | | | | | | | | | | | | | | | | | | The 11ad spec requires 11ad devices to be able to receive 8KB packets over the air. Currently this is only possible by loading the driver with mtu_max=7912 but this also forces a smaller block ACK window size which reduces performance for stations which transmit normal sized packets (<2KB). Fix this problem as follows: 1. Add a module parameter rx_large_buf that when set, will allocate 8KB RX buffers regardless of mtu_max setting. 2. When receiving block ACK request agree to any window size not above our maximum, regardless of the mtu_max setting. This means if the other side transmits small packets (2KB) it can still set up block ACK with a large window size, and get better performance.

* | wil6210: store bss object and use cfg80211_connect_bss()Dedy Lansky2017-04-09
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | In a fast disconnect/connect sequence, cfg80211_connect_result() can fail to find the bss object which the driver is connecting to. Detailed sequence of events: * Driver is connected in STA mode * Disconnect request arrives from user space. Driver disconnects and calls cfg80211_disconnected() which adds new event to the cfg80211_wq worker thread * Connect request arrives from user space. cfg80211_connect() stores ssid/ssid_len and calls rdev_connect() * __cfg80211_disconnected() runs in worker thread and zero wdev->ssid_len * Connect succeeds. Driver calls cfg80211_connect_result() which fails to find the bss because wdev->ssid_len is zero To overcome this, upon connect request, store the bss object in the driver and upon connect completion pass it to kernel using cfg80211_connect_bss().

| | | | | | | | | | | | | | | | | New sysfs entry "thermal_throttling" can be used to configure boundaries of each thermal zone. There are two sets of configurations, one for baseband and one for rf. Each config contains 3 thermal zones: high, max, critical. Each zone has high and low temperature set points (in Celsius). The format for writing is a series of 12 unsigned bytes: <bb_zone1_high> <bb_zone1_low> <bb_zone2_high> <bb_zone2_low> \ <bb_zone3_high> <bb_zone3_low> <rf_zone1_high> <rf_zone1_low> \ <rf_zone2_high> <rf_zone2_low> <rf_zone3_high> <rf_zone3_low> To disable thermal throttling for baseband or for rf, use 0 for all its six set points.

In case disable_ap_sme is true, driver doesn't turn-on WIPHY_FLAG_HAVE_AP_SME and the responsibility for AP SME is passed to user space. With AP SME disabled, driver reports assoc request frame to user space which is then responsible for sending assoc response frame and for sending NL80211_CMD_NEW_STATION. Driver also reports disassoc frame to user space which should then send NL80211_CMD_DEL_STATION. NL80211_CMD_SET_STATION with NL80211_STA_FLAG_AUTHORIZED is used by user space to allow/disallow data transmit.

This mechanism will be improved further in the future to make more refined requests based on actual bandwidth.

Start standalone AOA measurement 5. Receive AOA results Change-Id: I54ebc1bdff6ed7d91644165b16eb0a4240069321 CRs-Fixed: 1057307 Signed-off-by: Lior David <liord@codeaurora.org>
* wil6210: extract firmware version from file headerLior David2016-09-30
| | | | | | | | | | | | | | | | | | Currently the FW version is taken from the sw_version field of the FW ready event. This version is based on internal version control revision and it is difficult to map to actual FW version. Fix this by using the actual FW version stored in the FW file header record.

* wil6210: fix protection of wil->scan_requestMaya Erez2016-09-18
| | | | | | | | | | | | | | | | | | | | Currently the places that check wil->scan_request and call cfg80211_scan_done are not consistently protected, so there is a risk that cfg80211_scan_done will be called with NULL scan_request, causing a kernel crash. Fix this by using p2p_wdev_mutex in few other places that access scan_request. This makes sense since scan_request may point to p2p_wdev, and it is not worth the extra complexity of adding a new mutex.

* wil6210: prevent deep sleep of 60G device in critical pathsMaya Erez2016-06-07
| | | | | | | | | | | | | | | | | | | | | | In idle times 60G device can enter deep sleep and turn off its XTAL clock. Host access triggers the device power-up flow which will hold the AHB during XTAL stabilization until device switches from slow-clock to XTAL clock. This behavior can stall the PCIe bus for some arbitrary period of time. In order to prevent this stall, host can vote for High Latency Access Policy (HALP) before reading from PCIe bus. This vote will wakeup the device from deep sleep and prevent deep sleep until unvote is done.

* wil6210: P2P_DEVICE virtual interface supportLior David2016-05-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | Added support for the P2P_DEVICE virtual interface. This interface is intended for P2P management operations such as discovery and GO negotiation. Normally it is implemented by drivers to allow a separate interface for P2P management with its own MAC address, but for 11ad drivers it is needed to support P2P search, since it cannot otherwise be separated from normal scan. Since we only support a single interface/MAC address, we can't easily separate between primary and P2P_DEVICE interfaces. For example when a management packet arrives we can't tell for which interface it is intended. To work around this, we store a pointer to the interface where the last "radio operation" was triggered such as scan or remain on channel, and we forward management packets and scan results to this interface.

| | | | | | | | | | | | | | | | | | | wmi_evt_connect doesn't check if the connect event is received for an already connected station. This can lead to memory leak as a new vring is allocated without freeing the previously allocated vring and to unexpected behavior of nl80211 layer due to unexpected notification of a new station. Add a check in wmi_evt_connect in AP mode to verify that the requested CID is not associated to an already connected station.

| | | | | | | | | | | | | | | | | | | | | | | | In case there are multiple WMI commands with the same reply_id, the following scenario can occur: - Driver sends the first command to the device - The reply didn’t get on time and there is timeout - Reply_id, reply_buf and reply_size are set to 0 - Driver sends second wmi command with the same reply_id as the first - Driver sets wil->reply_id - Reply for the first wmi command arrives and handled by wmi_recv_cmd - As its ID fits the reply_id but the reply_buf is not set yet it is handled as a reply with event handler, and WARN_ON is printed This patch guarantee atomic setting of all the reply variables and prevents the above scenario.

* wil6210: handle multiple connect/disconnect eventsMaya Erez2016-03-23
| | | | | | | | | | | | | | | | | | | | | | In the current solution wil6210 configures the vring in a worker and holds only one pending CID. This implementation may lead to race conditions between connect and disconnect events of multiple stations or fast connect/disconnect events of the same station. In order to allow the removal of the connect worker and handling of WMI_VRING_CFG_DONE_EVENTID in the connect event, the WMI replies that provide the reply in a given buffer needs to be handled immediately in the WMI event interrupt thread. To prevent deadlocks, WMI replies that requires additional handling are still handled via the events list.

Taking the wmi_mutex in the reset flow when setting the FW ready bit to zero will prevent the above race condition.
