      USB: fix race between root-hub resume and wakeup requests · bf3d7d40
      Alan Stern 提交于
      The USB core keeps track of pending resume requests for root hubs, in
      order to resolve races between wakeup requests and suspends.  However
      the code that does this is subject to another race (between wakeup
      requests and resumes) because the WAKEUP_PENDING flag is cleared
      before the resume occurs, leaving a window in which another wakeup
      request might arrive.
      
      This patch (as1447) fixes the problem by clearing the WAKEUP_PENDING
      flag after the resume instead of before it.
      
      This fixes Bugzilla #24952.

      USB: prevent buggy hubs from crashing the USB stack · d199c96d
      Alan Stern 提交于
      If anyone comes across a high-speed hub that (by mistake or by design)
      claims to have no Transaction Translators, plugging a full- or
      low-speed device into it will cause the USB stack to crash.  This
      patch (as1446) prevents the problem by ignoring such devices, since
      the kernel has no way to communicate with them.

      USB SL811HS HCD: Fix memory leak in sl811h_urb_enqueue() · 2bd15f1f
      Jesper Juhl 提交于
      In drivers/usb/host/sl811-hcd.c::sl811h_urb_enqueue(), memory is allocated
      with kzalloc() and assigned to 'ep'. If we leave via the 'fail' label due
      to 'if (ep->maxpacket > H_MAXPACKET)', then 'ep' will go out of scope
      without having been assigned to anything, so we'll leak the memory we
      allocated.
      This patch fixes the leak by simply calling kfree(ep); before jumping to
      the 'fail' label.
