cx82310_eth: use skb_cow_head() to deal with cloned skbs

2018-01-17T08:38:52+00:00

commit a9e840a2081ed28c2b7caa6a9a0041c950b3c37d upstream.

We need to ensure there is enough headroom to push extra header,
but we also need to check if we are allowed to change headers.

skb_cow_head() is the proper helper to deal with this.

r8152: prevent the driver from transmitting packets with carrier off

2017-12-25T13:23:40+00:00

[ Upstream commit 2f25abe6bac573928a990ccbdac75873add8127e ]

The linking status may be changed when autosuspend. And, after
autoresume, the driver may try to transmit packets when the device
is carrier off, because the interrupt transfer doesn't update the
linking status, yet. And, if the device is in ALDPS mode, the device
would stop working.

The another similar case is
 1. unplug the cable.
 2. interrupt transfer queue a work_queue for linking change.
 3. device enters the ALDPS mode.
 4. a tx occurs before the work_queue is called.

The list rx_done would be initialized when the linking on occurs.

the following kernel panic would happen.

usbnet: fix alignment for frames with no ethernet header

2017-12-16T15:25:45+00:00

[ Upstream commit a4abd7a80addb4a9547f7dfc7812566b60ec505c ]

The qmi_wwan minidriver support a 'raw-ip' mode where frames are
received without any ethernet header. This causes alignment issues
because the skbs allocated by usbnet are "IP aligned".

Fix by allowing minidrivers to disable the additional alignment
offset. This is implemented using a per-device flag, since the same
minidriver also supports 'ethernet' mode.
