USB: usbtest: fix test number in log message

2013-01-07T18:34:20+00:00

This patch (as1639) fixes a minor bug in the usbtest driver.  Due to
concurrent changes, a test originally written as number 17 got changed
to number 24, but the corresponding change was not made in the log
message.  This updates the log message.

USB: usbtest: prevent a divide by zero bug

2012-11-21T21:32:26+00:00

If param->length is zero, then this could lead to a divide by zero bug
later in the function when we do: size %= max;

usb: misc: usbtest: send ISO packets for g_zero

2012-11-14T20:15:49+00:00

since commit b4036cc (usb: gadget: add
isochronous support to gadget zero), g_zero
has learned about isochronous transfers, which
allows us to use usbtest.ko to exercise
isochronous pipes.

All we need to do to enable that functionality
on usbtest.ko, is set the "iso" to 1 on
struct usbtest_info

usb: usbtest: two super speed fixes for usbtest

2012-05-01T17:38:27+00:00

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.

usb: usbtest: avoid integer overflow in alloc_sglist()

2012-04-17T22:54:57+00:00

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.

usb: usbtest: avoid integer overflow in test_ctrl_queue()

2012-04-17T22:54:57+00:00

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.

usb: Provide usb_speed_string() function

2011-09-18T08:29:04+00:00

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()

2011-08-23T16:47:40+00:00

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