2011-12-21HID: usbhid: hid-core: submit queued urbs before suspendDaniel Kurtz1-79/+105
If any userspace program has opened a keyboard device, the input core de-activates the keyboard's LEDs upon suspend(). It does this by sending individual EV_LED[LED_X]=0 events to the underlying device driver by directly calling the driver's registered event() handler. The usb-hid driver event() handler processes each request by immediately attempting to submit a CTRL URB to turn off the LED. USB URB submission is asynchronous. First the URB is added to the head of the ctrl queue. Then, if the CTRL_RUNNING flag is false, the URB is submitted immediately (and CTRL_RUNNING is set). If the CTRL_RUNNING flag was already true, then the newly queued URB is submitted in the ctrl completion handler when all previously submitted URBs have completed. When all queued URBs have been submitted, the completion handler clears the CTRL_RUNNING flag. In the 2-LED suspend case, at input suspend(), 2 LED event CTRL URBs get queued, with only the first actually submitted. Soon after input suspend() handler finishes, the usb-hid suspend() handler gets called. Since this is NOT a PM_EVENT_AUTO suspend, the handler sets REPORTED_IDLE, then waits for io to complete. Unfortunately, this usually happens while the first LED request is actually still being processed. Thus when the completion handler tries to submit the second LED request it fails, since REPORTED_IDLE is already set! This REPORTED_IDLE check failure causes the completion handler to complete, however without clearing the CTRL_RUNNING flag. This, in turn, means that the suspend() handler's wait_io() condition is never satisfied, and instead it times out after 10 seconds, aborting the original system suspend. This patch changes the behavior to the following: (1) allow completion handler to finish submitting all queued URBs, even if REPORTED_IDLE is set. This guarantees that all URBs queued before the hid-core suspend() call will be submitted before the system is suspended. (2) if REPORTED_IDLE is set and the URB queue is empty, queue, but don't submit, new URB submission requests. These queued requests get submitted when resume() flushes the URB queue. This is similar to the existing behavior, however, any requests that arrive while the queue is not yet empty will still get submitted before suspend. (3) set the RUNNING flag when flushing the URB queue in resume(). This keeps URBs that were queued in (2) from colliding with any new URBs that are being submitted during the resume process. The new URB submission requests upon resume get properly queued behind the ones being flushed instead of the current situation where they collide, causing memory corruption and oopses.

2011-11-23HID: usbkbd: synchronize LED URB submissionWillem Penninckx1-5/+58
usb_kbd_event() and usb_kbd_led() can be called concurrently, but they are not synchronized. They both readwrite kbd->leds, and usb_kbd_event() originally just checked the URB status field, while urb.h states that "It [status field] should not be examined before the URB is returned to the completion handler." To fix this unsynchronized behavior, this patch introduces a boolean representing whether the URB is submitted, and a spinlock.

This makes sure IO is never restarted while a reset is going on In particular there seems to be no protection from hid_retry_timeout() calling hid_start_in() which would start IO after hid_pre_reset() has already called hid_cease_io() because that uses del_timer(), not del_timer_sync() Signed-off-by: Oliver Neukum <oneukum@suse.de> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

Smatch has a new check for Rosenberg type information leaks where structs are copied to the user with uninitialized stack data in them.

Patch to add SiGma Micro-based keyboards (1c4f:0002) to hid-quirks. These keyboards dont seem to allow the records to be initialized, and hence a timeout occurs when the usbhid driver attempts to initialize them. The patch just adds the signature for these keyboards to the hid-quirks list with the setting HID_QUIRK_NO_INIT_REPORTS. This removes the 5-10 second wait for the timeout to occur.

2011-06-07HID: yurex: recognize GeneralKeys wireless presenter as generic HIDTomoki Sekiyama1-0/+2
Unfortunately, the device seems to have the same Vendor ID and Product ID as YUREX leg-shakes sensors, and the commit 6bc235a2e2 ("USB: add driver for Meywa-Denki & Kayac YUREX") added the ID to hid_ignore_list. I believe that we can distinguish YUREX and the Wireless Presenter by device type. The patch below makes the driver ignore only YUREX (bInterfaceProtocol==0), and recognize Wireless Presenter (bInterfaceProtocol is keyboard or mouse) as generic HID.

When hiddev_disconnect() runs with chardev open, it will proceed with usbhid_close(). When userspace in parallel runs the hiddev_release(), it sees !hiddev->exists (as it has been already set so by hiddev_disconnect()) and kfrees hiddev while hiddev_disconnect() hasn't finished yet.

2011-01-20kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERTDavid Rientjes1-1/+1
The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option is used to configure any non-standard kernel with a much larger scope than only small devices. This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes references to the option throughout the kernel. A new CONFIG_EMBEDDED option is added that automatically selects CONFIG_EXPERT when enabled and can be used in the future to isolate options that should only be considered for embedded systems (RISC architectures, SLOB, etc). Calling the option "EXPERT" more accurately represents its intention: only expert users who understand the impact of the configuration changes they are making should enable it.
