Currently, if macvlan in passthru mode is created and data are rxed and
you remove this device, following panic happens:
NULL pointer dereference at 0000000000000198
IP: [<ffffffffa0196058>] macvlan_handle_frame+0x153/0x1f7 [macvlan]
I'm using following script to trigger this:
<script>
while [ 1 ]
do
ip link add link e1 name macvtap0 type macvtap mode passthru
ip link set e1 up
ip link set macvtap0 up
IFINDEX=`ip link |grep macvtap0 | cut -f 1 -d ':'`
cat /dev/tap$IFINDEX >/dev/null &
ip link del dev macvtap0
done
</script>
I run this script while "ping -f" is running on another machine to send
packets to e1 rx.
Reason of the panic is that list_first_entry() is blindly called in
macvlan_handle_frame() even if the list was empty. vlan is set to
incorrect pointer which leads to the crash.
I'm fixing this by protecting port->vlans list by rcu and by preventing
from getting incorrect pointer in case the list is empty.

Make sure that the following steps are taken:
- drop packets sent by the VF with vlan tag
- block packets with vlan tag which are steered to the VF
- drop/block tagged packets when the policy is priority-tagged
- make sure VLAN stripping for received packets is set
- make sure force UP bit for the VF QP is set
Use enum values for all the above instead of numerical bit offsets.

Commit 4c09eed (net: fec: Enable imx6 enet checksum acceleration.)
enables hardware checksum acceleration unconditionally for all fec
variants. This is inappropriate, because some variants like imx5 have
no such support on hardware. Consequently, fec is broken on these
platforms. Fix it by enabling hardware checksum only on imx6q-fec type
of controllers.

GENERIC_GPIO now synonymous with GPIOLIB. There are no longer any valid
cases for enableing GENERIC_GPIO without GPIOLIB, even though it is
possible to do so which has been causing confusion and breakage. This
branch does the work to completely eliminate GENERIC_GPIO.
However, it is not trivial to just create a branch to remove it. Over
the course of the v3.9 cycle more code referencing GENERIC_GPIO has been
added to linux-next that conflicts with this branch. The following must
be done to resolve the conflicts when merging this branch into mainline:
* "git grep CONFIG_GENERIC_GPIO" should return 0 hits. Matches should be
replaced with CONFIG_GPIOLIB
* "git grep '\bGENERIC_GPIO\b'" should return 1 hit in the Chinese
documentation.
* Selectors of GENERIC_GPIO should be turned into selectors of GPIOLIB
* definitions of the option in architecture Kconfig code should be deleted.
Stephen has 3 merge fixup patches[1] that do the above. They are currently
applicable on mainline as of May 2nd.

A race condition exists when registering the first watchdog device.
Sequence of events:
- watchdog_register_device calls watchdog_dev_register
- watchdog_dev_register creates the watchdog misc device by calling
misc_register.
At that time, the matching character device (/dev/watchdog0) does not yet
exist, and old_wdd is not set either.
- Userspace gets an event and opens /dev/watchdog
- watchdog_open is called and sets wdd = old_wdd, which is still NULL,
and tries to dereference it. This causes the kernel to panic.
Seen with systemd trying to open /dev/watchdog immediately after
it was created.

A small bug in this code was causing the ALLMULTI filter to be set
when in fact we were just wanting to program a selective multicast list
to the hardware.
Fix that bug and remove a redundant if condition in the code that
follows.
This fixes wakeup behaviour when multicast WOL is enabled. Previously,
all multicast packets would wake up the system. Now, only those that the
host intended to receive trigger wakeups.

This can be readily reproduced when putting the XO-4 in a loop where
it goes to sleep due to inactivity, but then wakes up due to an
incoming ping. The error is hit within an hour or two.
This issue happens when an interrupt comes in early while host sleep
is still activated. Driver handles this case by auto cancelling host
sleep. However is_suspended flag is still set which prevents any cmd
or data from being sent to firmware. Fix it by clearing is_suspended
flag in this path.

Jake reported that since commit 1672c0e319
"mac80211: start auth/assoc timeout on frame status", he is unable to
connect to his AP, which is configured to use passive channel.
After switch to passive channel 4965 firmware drops any TX packet until
it receives beacon. Before commit 1672c0e3 we waited on channel and
retransmit packet after 200ms, that makes we receive beacon on the
meantime and association process succeed. New mac80211 behaviour cause
that any ASSOC frame fail immediately on iwl4965 and we can not
associate.
This patch restore old mac80211 behaviour for iwl4965, by removing
IEEE80211_HW_REPORTS_TX_ACK_STATUS feature. This feature will be
added again to iwl4965 driver, when different, more complex
workaround for this firmware issue, will be added to the driver.

Add handling of rx descriptor underflow. This fixes a fault that could
happen on slow machines, where data is received faster than the CPU can
handle. In such a case the device will use up all rx descriptors and
refuse to send any more data before confirming that it is ok. This
patch enables necessary interrupt to discover such a situation and will
handle them by dropping everything in the ring buffer.

The driver and firmware sync up through SYNC messages, and the
firmware's affirmative reply to these SYNC messages appears to be the
"Reset" indication received via the status interrupt endpoint. Thus the
driver needs the status interrupt endpoint always active so that the
Reset indication can be received even if the netdev is closed, which is
the case right after device insertion.
If the Reset indication is not received by the driver, it continues
sending SYNC messages to the firmware, which crashes about 10 seconds
later and the device stops responding.
