usb: usbtest: support container id descriptor test

2013-10-30T17:15:41+00:00

In Test 9 of usbtest module, it is used for performing chapter 9 tests N
times.

Container ID descriptor is one of the generic device-level capbility
descriptors which added in section 9.6.2.3 of USB 3.0 spec.

This patch adds to support getting Container ID descriptor test scenario
for USB 3.0.

usb: usbtest: fix checkpatch warning as sizeof code style

2013-10-29T23:43:36+00:00

Script checkpatch.pl always complains incorrect code style like below:

WARNING: sizeof *udev->bos->desc should be sizeof(*udev->bos->desc)

This patch fixes the warning for usbtest module.

usb: usbtest: bmAttributes would better be masked

2013-09-26T00:27:01+00:00

When transfer type is isochronous, the other bits (bits 5..2) of
bmAttributes in endpoint descriptor might not be set zero. So it's better
to use usb_endpoint_type routine to mask bmAttributes with
USB_ENDPOINT_XFERTYPE_MASK to judge the transfter type later.

USB: simplify the interface of usb_get_status()

2013-08-01T00:29:02+00:00

This patch simplifies the interface presented by usb_get_status().
Instead of forcing callers to check for the proper data length and
convert the status value to host byte order, the function will now
do these things itself.

USB: altsetting overrides for usbtest

2013-01-31T09:09:19+00:00

The usbtest driver includes some rather simple-minded logic for
selecting an altsetting to test.  It doesn't work well for the g_zero
gadget, because it selects altsetting 0 (which doesn't have
isochronous endpoints) rather than altsetting 1 (which does have them,
if the gadget's hardware supports them).  This prevents usbtest's
isochronous tests (15, 16, 22, and 23) from working with g_zero.

Since g_zero is one of the most common gadget drivers used for USB
testing, usbtest should do a better job of supporting it.  But since
some programs may rely on the current scheme for selecting
altsettings, I didn't want to change it.

Instead, this patch (as1655) adds a module parameter to usbtest, which
can be used to override the default altsetting.  Since usbtest is
never used by normal users (most distributions probably don't even
build it), the new module parameter won't inconvenience anybody.  In
any case, it is entirely optional -- leaving it unset preserves the
existing behavior.

The patch also fixes a related bug in usbtest: After selecting an
altsetting, the driver neglects to store its selection.

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;
