This patch fixes a potential security issue in the whiteheat USB driver which might allow a local attacker to cause kernel memory corrpution. This is due to an unchecked memcpy into a fixed size buffer (of 64 bytes). On EHCI and XHCI busses it's possible to craft responses greater than 64 bytes leading a buffer overflow.

Merge tag 'usb-serial-3.17-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/johan/usb-serial into work-linus Johan writes: USB-serial fixes for v3.17-rc2 These updates fix the log level for some option log messages that started bothering people after a recent change. They also fix some issues reported against the zte_ev driver by moving most device ids back from the zte_ev driver to the option driver (and removing two duplicate ids). The zte_ev driver is planned to be removed in 3.18. Some new device ids are also added. Signed-off-by: Johan Hovold <johan@kernel.org>

When we manually need to move the TR dequeue pointer we need to set the correct cycle bit as well. Previously we used the trb pointer from the last event received as a base, but this was changed in commit 1f81b6d2 ("usb: xhci: Prefer endpoint context dequeue pointer") to use the dequeue pointer from the endpoint context instead It turns out some Asmedia controllers advance the dequeue pointer stored in the endpoint context past the event triggering TRB, and this messed up the way the cycle bit was calculated. Instead of adding a quirk or complicating the already hard to follow cycle bit code, the whole cycle bit calculation is now simplified and adapted to handle event and endpoint context dequeue pointer differences.

The commit [5ee0f803: usbcore: don't log on consecutive debounce failures of the same port] added the check of the reliable port, but it also replaced the device argument to dev_err() wrongly, which leads to a NULL dereference. This patch restores the right device, port_dev->dev. Also, since dev_err() itself shows the port number, reduce the port number shown in the error message, essentially reverting to the state before the commit 5ee0f803.

This reverts commit 73228a05 ("USB: option,zte_ev: move most ZTE CDMA devices to zte_ev"). Move the IDs of the devices that were previously driven by the option driver back to that driver. As several users have reported, the zte_ev driver is causing random disconnects as well as reconnect failures. A closer analysis of the zte_ev setup code reveals that it consists of standard CDC requests (SET/GET_LINE_CODING and SET_CONTROL_LINE_STATE) but unfortunately fails to get some of those right. In particular, as reported by Liu Lei, it fails to lower DTR/RTS on close. It also appears that the control requests lack the interface argument. Note that the zte_ev driver is based on code (once) distributed by ZTE that still appears to originally have been reverse-engineered and bolted onto the generic driver. Since line control is already handled properly by the option driver, and the SET/GET_LINE_CODING requests appears to be redundant (amounts to a SET 9600 8N1), this is a first step in ultimately removing the redundant zte_ev driver. Note that AC2726 had already been moved back to option, and that some IDs were in the device table of both drivers prior to the commit being reverted.

Do not log normal interrupt-urb shutdowns as errors. The option driver has always been logging any nonzero interrupt-urb status as an error, including when the urb is killed during normal operation. Commit 9096f1fb ("USB: usb_wwan: fix potential NULL-deref at resume") moved the interrupt urb submission from port probe and release to open and close, thus potentially increasing the number of these false-positive error messages dramatically.
