-Vendor HAL Threading Model
-==========================
-The vendor HAL service has two threads:
-1. HIDL thread: This is the main thread which processes all the incoming HIDL
-RPC's.
-2. Legacy HAL event loop thread: This is the thread forked off for processing
-the legacy HAL event loop (wifi_event_loop()). This thread is used to process
-any asynchronous netlink events posted by the driver. Any asynchronous
-callbacks passed to the legacy HAL API's are invoked on this thread.
-
-Synchronization Concerns
-========================
-wifi_legacy_hal.cpp has a bunch of global "C" style functions to handle the
-legacy callbacks. Each of these "C" style function invokes a corresponding
-"std::function" version of the callback which does the actual processing.
-The variables holding these "std::function" callbacks are reset from the HIDL
-thread when they are no longer used. For example: stopGscan() will reset the
-corresponding "on_gscan_*" callback variables which were set when startGscan()
-was invoked. This is not thread safe since these callback variables are
-accesed from the legacy hal event loop thread as well.
-
-Synchronization Solution
-========================
-Adding a global lock seems to be the most trivial solution to the problem.
-a) All of the asynchronous "C" style callbacks will acquire the global lock
-before invoking the corresponding "std::function" callback variables.
-b) All of the HIDL methods will also acquire the global lock before processing
-(in hidl_return_util::validateAndCall()).
-
-Note: It's important that we only acquire the global lock for asynchronous
-callbacks, because there is no guarantee (or documentation to clarify) that the
-synchronous callbacks are invoked on the same invocation thread. If that is not
-the case in some implementation, we will end up deadlocking the system since the
-HIDL thread would have acquired the global lock which is needed by the
-synchronous callback executed on the legacy hal event loop thread.
