| * HID: sony: do not rely on hid_output_raw_reportBenjamin Tissoires2014-03-141-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | hid_out_raw_report is going to be obsoleted as it is not part of the unified HID low level transport documentation (Documentation/hid/hid-transport.txt) To do so, we need to introduce two new quirks: * HID_QUIRK_NO_OUTPUT_REPORTS_ON_INTR_EP: this quirks prevents the transport driver to use the interrupt channel to send output report (and thus force to use HID_REQ_SET_REPORT command) * HID_QUIRK_SKIP_OUTPUT_REPORT_ID: this one forces usbhid to not include the report ID in the buffer it sends to the device through HID_REQ_SET_REPORT in case of an output report This also fixes a regression introduced in commit 3a75b24949a8 (HID: hidraw: replace hid_output_raw_report() calls by appropriates ones). The hidraw API was not able to communicate with the PS3 SixAxis controllers in USB mode.

| |_|/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | implement() is setting bytes in LE data stream. 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.

It is protected by input_lock in HID core so only a single input event is handled at a time. USBHID can thus update the field unlocked and doesn't conflict with any HID vendor/device drivers. Note, many HID drivers make heavy use of hid_set_field() in that way. But usbhid also schedules a work to gather multiple LED changes in a single report. Hence, we used to lock the LED field update so the work can read a consistent state. However, hid_set_field() only writes a single integer field, which is guaranteed to be allocated all the time. So the worst possible race-condition is a garbage read on the LED field. Therefore, there is no need to protect the update. In fact, the only thing that is prevented by locking hid_set_field(), is an LED update while the scheduled work currently writes an older LED update out. However, this means, a new work is scheduled directly when the old one is done writing the new state to the device. So we actually _win_ by not protecting the write and allowing the write to be combined with the current write. A new worker is still scheduled, but will not write any new state. So the LED will not blink unnecessarily on the device. Assume we have the LED set to 0. Two request come in which enable the LED and immediately disable it. The current situation with two CPUs would be: usb_hidinput_input_event() | hid_led() ---------------------------------+---------------------------------- spin_lock(&usbhid->lock); hid_set_field(1); spin_unlock(&usbhid->lock); schedule_work(...); spin_lock(&usbhid->lock); __usbhid_submit_report(..1..); spin_unlock(&usbhid->lock); spin_lock(&usbhid->lock); hid_set_field(0); spin_unlock(&usbhid->lock); schedule_work(...); spin_lock(&usbhid->lock); __usbhid_submit_report(..0..); spin_unlock(&usbhid->lock); With the locking removed, we _might_ end up with (look at the changed __usbhid_submit_report() parameters in the first try!): usb_hidinput_input_event() | hid_led() ---------------------------------+---------------------------------- hid_set_field(1); schedule_work(...); spin_lock(&usbhid->lock); hid_set_field(0); schedule_work(...); __usbhid_submit_report(..0..); spin_unlock(&usbhid->lock); ... next work ... spin_lock(&usbhid->lock); __usbhid_submit_report(..0..); spin_unlock(&usbhid->lock); As one can see, we no longer send the "LED ON" signal as it is disabled immediately afterwards and the following "LED OFF" request overwrites the pending "LED ON". It is important to note that hid_set_field() is not atomic, so we might also end up with any other value. But that doesn't matter either as we _always_ schedule the next work with a correct value and schedule_work() acts as memory barrier, anyways. So in the worst case, we run __usbhid_submit_report(..<garbage>..) in the first case and the following __usbhid_submit_report() will write the correct value. But LED states are booleans so any garbage will be converted to either 0 or 1 and the remote device will never see invalid requests. Why all this? It avoids any custom locking around hid_set_field() in usbhid and finally allows us to provide a generic hidinput_input_event() handler for all HID transport drivers.

|/ | | | | | | | | | | | | | | | | Some multitouch screens do not like to be polled for input reports. However, the Win8 spec says that all touches should be sent during each report, making the initialization of reports unnecessary. The Win7 spec is less precise, so do not use this for those devices. Add the quirk HID_QUIRK_NO_INIT_INPUT_REPORTS so that we do not have to introduce a quirk for each problematic device. This quirk makes the driver behave the same way the Win 8 does. It actually retrieves the features, but not the inputs.

* HID: usbhid: quirk for Formosa IR receiverNicholas Santos2013-01-031-0/+1
| | | | | | | | | | | | Patch to add the Formosa Industrial Computing, Inc. Infrared Receiver [IR605A/Q] to hid-ids.h and hid-quirks.c. This IR receiver causes about a 10 second timeout when the usbhid driver attempts to initialze the device. Adding this device to the quirks list with HID_QUIRK_NO_INIT_REPORTS removes the delay.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the file has been open in non-blocking mode, EIO or ERESTARTSYS would never be returned even if they should (for example when device has been unplugged, you want EIO and not EAGAIN to be returned). Move the O_NONBLOCK check after other checks have been performed. Base on similar patch done to hidraw by Founder Fang <founder.fang@gmail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The USB recovery mode present in i.MX23 ROM emulates USB HID. It needs this quirk to behave properly. Even if the official branding of the chip is Freescale i.MX23, I named it Sigmatel STMP3780 since that's what the chip really is and it even reports itself as STMP3780.

| * HID: keep dev_rdesc unmodified and use it for comparisonsKevin Daughtridge2012-10-011-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The dev_rdesc member of the hid_device structure is meant to store the original report descriptor received from the device, but it is currently passed to any report_fixup method before it is copied to the rdesc member. This patch uses a temporary buffer to shield dev_rdesc from the side effects of many HID drivers' report_fixup implementations. usbhid's hid_post_reset checks the report descriptor currently returned by the device against a descriptor that may have been modified by a driver's report_fixup method. That leaves some devices nonfunctional after a resume, with a "reset_resume error 1" reported. This patch checks the new descriptor against the unmodified dev_rdesc instead and uses the original, instead of modified, report size.

| | | | | | | | | | | | | | | | | | | | | | | | | | For some reason, we had two IDs for the QUANTA 3001 touchscreen controller, one USB_DEVICE_ID_QUANTA_OPTICAL_TOUCH_3001 and one USB_DEVICE_ID_PIXART_IMAGING_INC_OPTICAL_TOUCH_SCREEN. As this has caused confusion, remove USB_DEVICE_ID_PIXART_IMAGING_INC_OPTICAL_TOUCH_SCREEN completely, and fix places where it was used to refer to USB_DEVICE_ID_QUANTA_OPTICAL_TOUCH_3001.
