| * hid: Fix up files needing export.h for EXPORT_SYMBOLPaul Gortmaker2011-10-31
| | | | | | | | | | | | | | | | | | With module.h being implicitly everywhere via device.h, the absence of explicitly including something for EXPORT_SYMBOL went unnoticed. Since we are heading to fix things up and clean module.h from the device.h file, we need to explicitly include these files now. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>

* | hid/apple: modern macbook airs use the standard apple function key translationsLinus Torvalds2011-11-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This removes the use of the special "macbookair_fn_keys" keyboard translation table for the MacBookAir4,x models (ie the 2011 refresh). They use the standard apple_fn_keys[] translation. Apparently only the old MacBook Air's need a different translation table. This mirrors the change that commit da617c7cb915 ("HID: consolidate MacbookAir 4,1 mappings") did for the WELLSPRING6A ones, but does it for the WELLSPRING6 model used on the MacBookAir4,2.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit 0db3bfc72adf0c (""HID: multitouch: decide if hid-multitouch needs to handle mt devices"). The generic detection of hid-mt devices has two major flaws, and was merged prematurely. Firstly, the hid-multitouch gets loaded even when the device is handled by a special device. Secondly, the patch only partially duplicates the device whitelist already present in hid-core, effectively rendering a number of devices non-functional.

This driver rewrites the raw report data from such keyboards into USB HID 1.11 compliant report data. It only matches the USB vendor and product IDs for the keyboard it has been tested on. Since there are several keyboards, notably a number of laptops and folding USB keyboards known to have similar unresolved problem reports, the list is expected to grow.

The HID bus normally immediately probes an appropriate driver which then handles HID input for this device. The ll driver now uses the hid_input_report() function to report input events for a specific device. However, if the HID bus unloads the driver at the same time (for instance via a call to /sys/bus/hid/devices/<dev>/unbind) then the hdev->driver pointer may be used by hid_input_report() and hid_device_remove() at the same time which may cause hdev->driver to point to invalid memory. This fix adds a semaphore to every hid device which protects hdev->driver from asynchronous access. This semaphore is locked during driver *_probe and *_remove and also inside hid_input_report(). The *_probe and *_remove functions may sleep so the semaphore is good here, however, hid_input_report() is in atomic context and hence only uses down_trylock(). If it cannot acquire the lock it simply drops the input package. The low-level drivers report input events synchronously so hid_input_report() should never be entered twice at the same time on the same device. Hence, the lock should always be available. But if the driver is currently probed/removed then the lock is not available and dropping the package should be safe because this is what would have happened if the package arrived some milliseconds earlier/later. This also fixes another race condition while probing drivers: First the *_probe function of the driver is called and only if that succeeds, the related input device of hidinput is registered. If the low level driver reports input events after the *_probe function returned but before the input device is registered, then a NULL pointer dereference will occur. (Equivalently on driver remove function). This is not possible anymore, since the semaphore lock drops all incoming packages until the driver/device is fully initialized.

This patch makes hid-magicmouse correctly only report one real button for Magic Trackpad, which in turn makes Xorg enable multi-finger click support to emulate right/middle buttons.

However the device_destroy() call can cause a userland read/write to return with an error. It may cause the program to release the file descripter before the disconnect is finished. hidraw_disconnect() has already set hidraw->exist to 0, which makes hidraw_release() kfree the hidraw structure, which hidraw_disconnect() continues to access and even tries to kfree again. Similarly if a hidraw_release() occurs after setting hidraw->exist to 0, the same thing can happen. This is fixed by expanding the mutex critical section to cover the whole function from setting hidraw->exist to 0 to freeing the hidraw structure, preventing a hidraw_release() from interfering.

Many initializations require multiple memory requests to be sent synchronously so we need a way to lock the stream and release it when we are done. This adds several helper functions which allow to lock the stream, then send requests, wait for the answers and release the stream again. When holding the lock, the function may sleep and interrupted by signals. Also it returns after a short timeout so userspace shouldn't notice long delays.

This adds support to access this memory and handle memory events. There are two macros which wrap up the memory access functions to avoid accidentally overwriting sensitive eeprom data because a boolean value was wrongly set.

This adds handlers for these DRMs but discards extension data since we do not support it, yet. It prints a warning to kernel log if an unhandled report is catched. Since we handle all requests now, this should never happen, though. Signed-off-by: David Herrmann <dh.herrmann@googlemail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

Since we can turn the IR cam on and off, we register a separate input device so we can react on open/close callbacks to save wiimote battery power when IR cam is not needed. The cam can be in four states: off, basic, extended and full The DRM chooser automatically selects a proper DRM that includes all required IR data so no information is lost.

The data is almost always reported in the same format, so we can use a single handler. However, an own handler function is created for each DRM-mode because when IR and extension support is added, each of them is parsed differently. Also set the appropriate DRM including accelerometer data on DRM requests to actually retrieve the accelerometer data. Data is reported to userspace as ABS_RX/Y/Z values. The values are between -500 and 500 and 0 means no acceleration. See also userspace xwiimote library for data parsing.
