USB: cdc-acm: fix TIOCMIWAIT

2016-11-10T12:12:59+00:00

The TIOCMIWAIT implementation would return -EINVAL if any of the three
supported signals were included in the mask.

Instead of returning an error in case TIOCM_CTS is included, simply
drop the mask check completely, which is in accordance with how other
drivers implement this ioctl.

cdc-acm: fix uninitialized variable

2016-11-07T09:15:22+00:00

variable struct usb_cdc_parsed_header h may be used
uninitialized in acm_probe.

In kernel 4.8.

    /* handle quirks deadly to normal probing*/
    if (quirks == NO_UNION_NORMAL)

        ...

        goto skip_normal_probe;
    }

we bypass call to

    cdc_parse_cdc_header(&h, intf, buffer, buflen);

but later use h in

    if (h.usb_cdc_country_functional_desc) { /* export the country data */

Revert "usbtmc: convert to devm_kzalloc"

2016-09-28T09:51:30+00:00

This reverts commit e6c7efdcb76f11b04e3d3f71c8d764ab75c9423b.

Turns out it was totally wrong.  The memory is supposed to be bound to
the kref, as the original code was doing correctly, not the
device/driver binding as the devm_kzalloc() would cause.

This fixes an oops when read would be called after the device was
unbound from the driver.

cdc-acm: hardening against malicious devices

2016-09-21T07:48:27+00:00

This should fix the last holes against malicious devices
still open in cdc-acm. It cannot go into stable due to
the introduction of the common parser.
The fix for stable already merged also covers the problems this patch
fixes.

cdc-acm: delete obsolete debug messages

2016-09-09T12:13:24+00:00

Some debug messages merely provide a function trace without
additional debug data. They predate ftrace and can be replaced
by it. Drop them without replacement.
