catc: Use heap buffer for memory size test

2017-03-16T02:18:48+00:00

commit 2d6a0e9de03ee658a9adc3bfb2f0ca55dff1e478 upstream.

Allocating USB buffers on the stack is not portable, and no longer
works on x86_64 (with VMAP_STACK enabled as per default).

cdc_ncm: toggle altsetting to force reset before setup

2016-04-30T22:05:26+00:00

[ Upstream commit 48906f62c96cc2cd35753e59310cb70eb08cc6a5 ]

Some devices will silently fail setup unless they are reset first.
This is necessary even if the data interface is already in
altsetting 0, which it will be when the device is probed for the
first time.  Briefly toggling the altsetting forces a function
reset regardless of the initial state.

This fixes a setup problem observed on a number of Huawei devices,
appearing to operate in NTB-32 mode even if we explicitly set them
to NTB-16 mode.

usbnet: cleanup after bind() in probe()

2016-04-30T22:05:24+00:00

commit 1666984c8625b3db19a9abc298931d35ab7bc64b upstream.

In case bind() works, but a later error forces bailing
in probe() in error cases work and a timer may be scheduled.
They must be killed. This fixes an error case related to
the double free reported in
http://www.spinics.net/lists/netdev/msg367669.html
and needs to go on top of Linus' fix to cdc-ncm.

asix: silence log message from oversize packet

2016-02-13T10:34:05+00:00

commit b70183db83552cf63cac51406aaf76a2cf5fca73 upstream.

Since it is possible for an external system to send oversize packets
at anytime, it is best for driver not to print a message and spam
the log (potential external DoS).

asix: Do full reset during ax88772_bind

2015-11-17T15:54:46+00:00

[ Upstream commit 436c2a5036b6ffe813310df2cf327d3b69be0734 ]

commit 3cc81d85ee01 ("asix: Don't reset PHY on if_up for ASIX 88772")
causes the ethernet on Arndale to no longer function. This appears to
be because the Arndale ethernet requires a full reset before it will
function correctly, however simply reverting the above patch causes
problems with ethtool settings getting reset.

It seems the problem is that the ethernet is not properly reset during
bind, and indeed the code in ax88772_bind that resets the device is a
very small subset of the actual ax88772_reset function. This patch uses
ax88772_reset in place of the existing reset code in ax88772_bind which
removes some code duplication and fixes the ethernet on Arndale.

It is still possible that the original patch causes some issues with
suspend and resume but that seems like a separate issue and I haven't
had a chance to test that yet.

asix: Don't reset PHY on if_up for ASIX 88772

2015-11-17T15:54:46+00:00

[ Upstream commit 3cc81d85ee01e5a0b7ea2f4190e2ed1165f53c31 ]

I've noticed every time the interface is set to 'up,', the kernel
reports that the link speed is set to 100 Mbps/Full Duplex, even
when ethtool is used to set autonegotiation to 'off', half
duplex, 10 Mbps.
It can be tested by:
 ifconfig eth0 down
 ethtool -s eth0 autoneg off speed 10 duplex half
 ifconfig eth0 up

Then checking 'dmesg' for the link speed.

net: asix: add missing flag to struct driver_info

2014-04-09T01:20:46+00:00

commit d43ff4cd798911736fb39025ec8004284b1b0bc2 upstream.

The struct driver_info ax88178_info is assigned the function
asix_rx_fixup_common as it's rx_fixup callback. This means that
FLAG_MULTI_PACKET must be set as this function is cloning the
data and calling usbnet_skb_return. Not setting this flag leads
to usbnet_skb_return beeing called a second time from within
the rx_process function in the usbnet module.
