USB: fix buffer overflows with parsing CDC headers

2017-11-30T08:35:54+00:00

Parsing CDC headers a buffer overflow cannot just be prevented
by checking that the remainder of the buffer is longer than minimum
length. The size of the fields to be parsed must be figured in, too.

In newer kernels this issue has been fixed at a central location with

    USB: core: harden cdc_parse_cdc_header

on anything older the parsing had not been centralised, so a separate
fix for each driver is necessary.

cdc-ether: handle promiscuous mode with a set_rx_mode callback

2014-10-28T21:26:20+00:00

Promiscuous mode was not supported anymore with my Lenovo adapters
(RTL8153) since commit c472ab68ad67db23c9907a27649b7dc0899b61f9
(cdc-ether: clean packet filter upon probe).

It was not possible to use them in a bridge anymore.

cdc-ether: extract usbnet_cdc_update_filter function

2014-10-28T21:26:19+00:00

This will be used by the set_rx_mode callback.

Also move a comment about multicast filtering in this new function.

cdc-ether: clean packet filter upon probe

2014-07-29T19:22:15+00:00

There are devices that don't do reset all the way. So the packet filter should
be set to a sane initial value. Failure to do so leads to intermittent failures
of DHCP on some systems under some conditions.

qmi_wwan/cdc_ether: move Novatel E371 (1410:9011) to qmi_wwan

2014-03-31T20:06:11+00:00

This device provides QMI and ethernet functionality via a standard CDC
ethernet descriptor.  But when driven by cdc_ether, the QMI
functionality is unavailable because only cdc_ether can claim the USB
interface. Thus blacklist the device in cdc_ether and add its IDs to
qmi_wwan, which enables both QMI and ethernet simultaneously.

r8152: disable the ECM mode

2014-03-06T01:40:24+00:00

There are known issues for switching the drivers between ECM mode and
vendor mode. The interrup transfer may become abnormal. The hardware
may have the opportunity to die if you change the configuration without
unloading the current driver first, because all the control transfers
of the current driver would fail after the command of switching the
configuration.

Although to use the ecm driver and vendor driver independently is fine,
it may have problems to change the driver from one to the other by
switching the configuration. Additionally, now the vendor mode driver
is more powerful than the ECM driver. Thus, disable the ECM mode driver,
and let r8152 to set the configuration to vendor mode and reset the
device automatically.

drivers/net: delete non-required instances of include

2014-01-16T19:53:26+00:00

None of these files are actually using any __init type directives
and hence don't need to include .   Most are just a
left over from __devinit and __cpuinit removal, or simply due to
code getting copied from one driver to the next.

This covers everything under drivers/net except for wireless, which
has been submitted separately.

r8152: ecm and vendor modes coexist

2014-01-15T02:48:54+00:00

Remove the limitation that the ecm and r8152 drivers couldn't coexist.
 - Remove the devices from the blacklist of relative drivers.
 - Remove usb_driver_set_configuration() from r8152 driver.
 - Modify the id_table of the r8152 driver for the vendor mode only.

usb: Fix FSF address in file headers

2013-12-06T17:37:55+00:00

Several files refer to an old address for the Free Software Foundation
in the file header comment.  Resolve by replacing the address with
the URL  so that we do not have to keep
updating the header comments anytime the address changes.
