* | | | wil6210: fix race conditions between TX send and completionMaya Erez2016-06-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are 2 possible race conditions, both are solved by addition of memory barrier: 1. wil_tx_complete reads the swhead to determine if the vring is empty. In case the swhead was updated before the descriptor update was performed in __wil_tx_vring/__wil_tx_vring_tso, the completion loop will not end and as the DU bit may still be set from a previous run, this skb can be handled as completed before it was sent, which will lead to double free of the same SKB. 2. __wil_tx_vring/__wil_tx_vring_tso calculate the number of available descriptors according to the swtail. In case the swtail is updated before memset of ctx to zero is completed, we can handle this descriptor while later on ctx is zeroed.

* | | | wil6210: add support for device led configurationMaya Erez2016-06-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add the ability to configure the device led to be used for notifying the AP activity (60G device supports leds 0-2). The host can also configure the blinking frequency of the led in three states.

* | | | 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.

Because wil_p2p_cancel_listen was not protected, user space could start a new P2P listen/search before wmi_stop_discovery completed. This caused a crash in the firmware. 2. In P2P listen, when listen timer expires and user space calls cancel_remain_on_channel at the same time, code could send the cfg80211_remain_on_channel_expired notification twice. Added protections with wil->mutex to several places that call wmi_stop_discovery.

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.

For example, stations inside a PBSS can communicate directly, and the PCP role can be transferred between stations. This change adds PBSS support, and has 2 main parts: 1. When starting an AP, add an option to start as a PCP instead. This is implemented by a new PBSS flag which is passed as part of the cfg80211_ap_settings structure. 2. When connecting to a BSS, add an option to connect to a PCP instead of an AP. This is again implemented by a new PBSS flag, added to the cfg80211_connect_params structure.

This will allow better sync between teams in the future and avoid bugs because of unexpected API changes. The wmi.h will have many differences but most are cosmetic. It also includes these real differences: 1. is_go parameter added to BCON_CTRL and START_PCP commands. 2. max_rx_pl_per_desc added to CFG_RX_CHAIN command. 3. various small API updates that are not currently used by driver.

* | | wil6210: add support for discovery mode during scanLior David2016-04-05

When discovery mode is active, station transmits special beacons while scanning. This can optimize the scan mainly when there is only one AP/PCP around. Discovery mode is implicitly used by firmware during P2P search. Since there is currently no use case where user space has a reason to directly control discovery mode, we expose it only through a debugfs flag. Also fix name confusion in the wmi_scan_type enumeration. The type previously called WMI_LONG_SCAN is actually WMI_ACTIVE_SCAN.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | WMI synchronous handling has changed and WMI calls that provide a buffer for the reply are completed in the WMI interrupt context. This allows sending the RX and TX BACK commands from the WMI event handler without the need for the worker thread. This is a better approach as it can decrease the handshake time in the connect flow and prevent race conditions in case of fast disconnects. An example for such a race is handling of wil_back_rx_handle during a disconnect event, as wil_back_rx_handle is not protected by the wil mutex and a disconnect can be handled after sta->status is verified as connected.
