usb: usbtest: two super speed fixes for usbtest

2012-06-01T07:18:21Z

commit 6a23ccd216b6a8ba2c67a9f9d8969b4431ad2920 upstream. bMaxPacketSize0 field for super speed is a power of 2, not a count. The size itself is always 512. Max packet size for a super speed bulk endpoint is 1024, so allocate the urb size in halt_simple() accordingly. Signed-off-by: Paul Zimmerman Acked-by: Felipe Balbi Signed-off-by: Greg Kroah-Hartman

usb: usbtest: avoid integer overflow in alloc_sglist()

2012-04-17T22:54:57Z

A large `nents' from userspace could overflow the allocation size, leading to memory corruption. | alloc_sglist() | usbtest_ioctl() Use kmalloc_array() to avoid the overflow. Signed-off-by: Xi Wang Acked-by: Alan Stern Signed-off-by: Greg Kroah-Hartman

usb: usbtest: avoid integer overflow in test_ctrl_queue()

2012-04-17T22:54:57Z

Avoid overflowing context.count = param->sglen * param->iterations, where both `sglen' and `iterations' are from userspace. | test_ctrl_queue() | usbtest_ioctl() Keep -EOPNOTSUPP for error code. Signed-off-by: Xi Wang Acked-by: Alan Stern Signed-off-by: Greg Kroah-Hartman

usb: Provide usb_speed_string() function

2011-09-18T08:29:04Z

In a few places in the kernel, the code prints a human-readable USB device speed (eg. "high speed"). This involves a switch statement sometimes wrapped around in ({ ... }) block leading to code repetition. To mitigate this issue, this commit introduces usb_speed_string() function, which returns a human-readable name of provided speed. It also changes a few places switch was used to use this new function. This changes a bit the way the speed is printed in few instances at the same time standardising it.

USB: use usb_endpoint_maxp() instead of le16_to_cpu()

2011-08-23T16:47:40Z

Now ${LINUX}/drivers/usb/* can use usb_endpoint_maxp(desc) to get maximum packet size instead of le16_to_cpu(desc->wMaxPacketSize).

USB: usbtest: use URB_ZERO_PACKET for BULK-OUT transfers

2011-08-23T16:47:39Z

Executing | testusb -a -c 1 -t 3 -v 421 -s 2048 does not complete on the gadget side. g_zero enqueues a 4096 bytes long buffer. The host sends 2048bytes which is a multiple of wMaxPacketSize (either 64 or 512 bytes). The host is done with sending data but the gadget waits for more. Since the protocol does not include transfer-length-field sending a terminating zero packet seems the only way out.

usb: fix warning in usbtest module v2

On amd64 unsigned is not as wide as pointer and this causes a compiler warning. Switching to unsigned long corrects the problem. Signed-off-by: Greg Dietsche Signed-off-by: Greg Kroah-Hartman
