usb: cdc-wdm: resp_count can be 0 even if WDM_READ is set

2014-01-13T04:13:28Z

Do not decrement resp_count if it's already 0. We set resp_count to 0 when the device is closed. The next open and read will try to clear the WDM_READ flag if there was leftover data in the read buffer. This fix is necessary to prevent resubmitting the read URB in a tight loop because resp_count becomes negative. The bug can easily be triggered from userspace by not reading all data in the read buffer, and then closing and reopening the chardev.

usb: delete non-required instances of include

2014-01-08T23:01:39Z

None of these files are actually using any __init type directives and hence don't need to include . Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next. Signed-off-by: Paul Gortmaker Signed-off-by: Greg Kroah-Hartman

usb: cdc-wdm: avoid hanging on zero length reads

2013-12-20T20:06:46Z

commit 73e06865ead1 ("USB: cdc-wdm: support back-to-back USB_CDC_NOTIFY_RESPONSE_AVAILABLE notifications") implemented queued response handling. This added a new requirement: The read urb must be resubmitted every time we clear the WDM_READ flag if the response counter indicates that the device is waiting for a read. Fix by factoring out the code handling the WMD_READ clearing and possible urb submission, calling it everywhere we clear the flag. Without this fix, the driver ends up in a state where the read urb is inactive, but the response counter is positive after a zero length read. This prevents the read urb from ever being submitted again and the driver appears to be hanging.
