3.13.11.7 -stable review patch. If anyone has any objections, please let me know.
------------------ From: Oliver Neukum <oneu...@suse.de> commit d310d05f1225d1f6f2bf505255fdf593bfbb3051 upstream. usbfs allows user space to pass down an URB which sets URB_SHORT_NOT_OK for output URBs. That causes usbcore to log messages without limit for a nonsensical disallowed combination. The fix is to silently drop the attribute in usbfs. The problem is reported to exist since 3.14 https://www.virtualbox.org/ticket/13085 Signed-off-by: Oliver Neukum <oneu...@suse.de> Acked-by: Alan Stern <st...@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gre...@linuxfoundation.org> Signed-off-by: Kamal Mostafa <ka...@canonical.com> --- drivers/usb/core/devio.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/usb/core/devio.c b/drivers/usb/core/devio.c index 967152a..74185cc 100644 --- a/drivers/usb/core/devio.c +++ b/drivers/usb/core/devio.c @@ -1411,7 +1411,7 @@ static int proc_do_submiturb(struct dev_state *ps, struct usbdevfs_urb *uurb, u = (is_in ?
