* HID: Add a new id 0x501a for Genius MousePen i608XGiedrius Statkevičius2014-12-291-0/+1
| | | | | | | | | | | | | | | | | | | | New Genius MousePen i608X devices have a new id 0x501a instead of the old 0x5011 so add a new #define with "_2" appended and change required places. The remaining two checkpatch warnings about line length being over 80 characters are present in the original files too and this patch was made in the same style (no line break). Just adding a new id and changing the required places should make the new device work without any issues according to the bug report in the following url. This patch was made according to and fixes: https://bugzilla.kernel.org/show_bug.cgi?id=67111 Signed-off-by: Giedrius Statkevičius <giedrius.statkevicius@gmail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

| | * | | HID: usbhid: prevent unwanted events to be sent when re-opening the deviceBenjamin Tissoires2014-10-292-12/+25
| | | |/ | | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When events occurs while no one is listening to the node (hid->open == 0 and usb_kill_urb() called) some events are still stacked somewhere in the USB (kernel or device?) stack. When the node gets reopened, these events are drained, and this results in spurious touch down/up, or mouse button clicks. The problem was spotted with touchscreens in fdo bug #81781 [1], but it actually occurs with any mouse using hid-generic or touchscreen. A way to reproduce it is to call: $ xinput disable 9 ; sleep 5 ; xinput enable 9 With 9 being the device ID for the touchscreen/mouse. During the "sleep", produce some touch events or click events. When "xinput enable" is called, at least one click is generated. This patch tries to fix this by draining the queue for 50 msec and during this time frame, not forwarding these old events to the hid layer. Hans completed the explanation: """ Devices like mice (basically any hid device) will have a fifo on the device side, when we stop submitting urbs to get hid reports from it, that fifo will fill up, and when we resume we will get whatever is there in that fifo.

| | | * HID: usbhid: improve handling of Clear-Halt and resetAlan Stern2014-09-031-25/+9
| | |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch changes the way usbhid carries out Clear-Halt and reset. Currently, after a Clear-Halt on the interrupt-IN endpoint, the driver immediately restarts the interrupt URB, even if the Clear-Halt failed. This doesn't work out well when the reason for the failure was that the device was disconnected (when a low- or full-speed device is connected through a hub to an EHCI controller, transfer errors caused by disconnection are reported as stalls by the hub). Instead now the driver will attempt a reset after a failed Clear-Halt. The way resets are carried out is also changed. Now the driver will call usb_queue_reset_device() instead of calling usb_reset_device() directly. This avoids a deadlock that would arise when a device is unplugged: The hid_reset() routine runs as a workqueue item, a reset attempt after the device has been unplugged will fail, failure will cause usbhid to be unbound, and the disconnect routine will try to do cancel_work_sync(). The usb_queue_reset_device() implementation is carefully written to handle scenarios like this one properly.

Without this quirk the device keeps disconnecting from the bus (and is re-enumerated) unless opened (and kept open, should an input event occur). Note that while the device can be run-time suspended, the autosuspend timeout must be high enough to allow the device to be polled at least once before being suspended. Specifically, using autosuspend_delay_ms=0 will still cause the device to disconnect on input events. Signed-off-by: Johan Hovold <johan@kernel.org> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

In case the data is not aligned to 64bits, it reads past the allocated buffer. It doesn't really change any value there (it's properly bitmasked), but in case that this read past the boundary hits a page boundary, pagefault happens when accessing 64bits of 'x' in implement(), and kernel oopses. This happens much more often when numbered reports are in use, as the initial 8bit skip in the buffer makes the whole process work on values which are not aligned to 64bits. This problem dates back to attempts in 2005 and 2006 to make implement() and extract() as generic as possible, and even back then the problem was realized by Adam Kroperlin, but falsely assumed to be impossible to cause any harm: http://www.mail-archive.com/linux-usb-devel@lists.sourceforge.net/msg47690.html I have made several attempts at fixing it "on the spot" directly in implement(), but the results were horrible; the special casing for processing last 64bit chunk and switching to different math makes it unreadable mess. I therefore took a path to allocate a few bytes more which will never make it into final report, but are there as a cushion for all the 64bit math operations happening in implement() and extract(). All callers of hid_output_report() are converted at the same time to allocate the buffer by newly introduced hid_alloc_report_buf() helper. Bruno noticed that the whole raw_size test can be dropped as well, as hid_alloc_report_buf() makes sure that the buffer is always of a proper size.
