Race between bonding_store_slaves_active() and slave manipulation
functions. The bond_for_each_slave use in bonding_store_slaves_active()
is not protected by any synchronization mechanism.
NULL pointer dereference is easy to reach.
Fixed by acquiring the bond->lock for the slave walk.

First I would give three observations which will be used later.
Observation 1: if (delayed_work_pending(wq)) cancel_delayed_work(wq)
This usage is wrong because the pending bit is cleared just before the
work's fn is executed and if the function re-arms itself we might end up
with the work still running. It's safe to call cancel_delayed_work_sync()
even if the work is not queued at all.
Observation 2: Use of INIT_DELAYED_WORK()
Work needs to be initialized only once prior to (de/en)queueing.
Observation 3: IFF_UP is set only after ndo_open is called
Related race conditions:
1. Race between bonding_store_miimon() and bonding_store_arp_interval()
Because of Obs.1 we can end up having both works enqueued.
2. Multiple races with INIT_DELAYED_WORK()
Since the works are not protected by anything between INIT_DELAYED_WORK()
and calls to (en/de)queue it is possible for races between the following
functions:
(races are also possible between the calls to INIT_DELAYED_WORK()
and workqueue code)
bonding_store_miimon() - bonding_store_arp_interval(), bond_close(),
bond_open(), enqueued functions
bonding_store_arp_interval() - bonding_store_miimon(), bond_close(),
bond_open(), enqueued functions
3. By Obs.1 we need to change bond_cancel_all()
Bugs 1 and 2 are fixed by moving all work initializations in bond_open
which by Obs. 2 and Obs. 3 and the fact that we make sure that all works
are cancelled in bond_close(), is guaranteed not to have any work
enqueued.
Also RTNL lock is now acquired in bonding_store_miimon/arp_interval so
they can't race with bond_close and bond_open. The opposing work is
cancelled only if the IFF_UP flag is set and it is cancelled
unconditionally. The opposing work is already cancelled if the interface
is down so no need to cancel it again. This way we don't need new
synchronizations for the bonding workqueue. These bugs (and fixes) are
tied together and belong in the same patch.
Note: I have left 1 line intentionally over 80 characters (84) because I
didn't like how it looks broken down. If you'd prefer it otherwise,
then simply break it.

Fix this wrong assignment by applying the available hardware timestamp to the

John W. Linville says:
====================
This is a batch of fixes intended for 3.7...
Included are two pulls. Regarding the mac80211 tree, Johannes says:
"Please pull my mac80211.git tree (see below) to get two more fixes for
3.7. Both fix regressions introduced *before* this cycle that weren't
noticed until now, one for IBSS not cleaning up properly and the other
to add back the "wireless" sysfs directory for Fedora's startup scripts."
Regarding the iwlwifi tree, Johannes says:
"Please also pull my iwlwifi.git tree, I have two fixes: one to remove a
spurious warning that can actually trigger in legitimate situations, and
the other to fix a regression from when monitor mode was changed to use
the "sniffer" firmware mode."
Also included is an nfc tree pull. Samuel says:
"We mostly have pn533 fixes here, 2 memory leaks and an early unlocking fix.
Moreover, we also have an LLCP adapter linked list insertion fix."
On top of that, a few more bits... Albert Pool adds a USB ID
to rtlwifi. Bing Zhao provides two mwifiex fixes -- one to fix
a system hang during a command timeout, and the other to properly
report a suspend error to the MMC core. Finally, Sujith Manoharan
fixes a thinko that would trigger an ath9k hang during device reset.

When the mdio-gpio driver is probed via device trees, the platform
device id is set as -1, However the pdev->id is re-used as bus-id for
while creating mdio gpio bus.
So
For device tree case the mdio-gpio bus name appears as "gpio-ffffffff"
where as
for non-device tree case the bus name appears as "gpio-<bus-num>"
Which means the bus_id is fixed in device tree case, so we can't have
two mdio gpio buses via device trees. Assigning a logical bus number
via device tree solves the problem and the bus name is much consistent
with non-device tree bus name.
Without this patch
1. we can't support two mdio-gpio buses via device trees.
2. we should always pass gpio-ffffffff as bus name to phy_connect, very
different to non-device tree bus name.
So, setting up the bus_id via aliases from device tree is the right
solution and other drivers do similar thing.

mdiobus_free"
This reverts commit aa731872f7d33dcb8b54dad0cfb82d4e4d195d7e.
As pointed out by Ben Hutchings, this change is not correct.
mdiobus_unregister() can't be called if the bus isn't registered yet,
however this change can result in situations which cause that to
happen.
Part of the confusion here revolves around the fact that the
callers of this module control registration/unregistration,
rather than the module itself.

The chip ready check added by the commit 3ac3546e [Always wait for
the chip to be ready] does not work when the register read/write
is word swapped. This check has been added before the WORD_SWAP
register is programmed, so we need to check for swapped register
value as well.
Bit 16 is marked as RESERVED in SMSC datasheet, Steve Glendinning
<steve@shawell.net> checked with SMSC and wrote:
The chip architects have concluded we should be reading PMT_CTRL
until we see any of bits 0, 8, 16 or 24 set. Then we should read
BYTE_TEST to check the byte order is correct (as we already do).
The rationale behind this is that some of the chip variants have
word order swapping features too, so the READY bit could actually
be in any of the 4 possible locations. The architects have confirmed
that if any of these 4 positions is set the chip is ready. The other
3 locations will either never be set or can only go high after READY
does (so also indicate the device is ready).
This change will check for the READY bit at the 16th position. We do
not check the other two cases (bit 8 and 24) since the driver does not
support byte-swapped register read/write.

In commit 175c0dff, drivers uses tasklet_kill to avoid put disabled tasklet
on the tasklet vec. But some of the drivers uses tasklet_init & tasklet_disable
in the driver init code, then tasklet_enable when it is opened. This makes
tasklet_enable on a killed tasklet and make ksoftirqd crazy then. Normally,
drivers should use tasklet_init/tasklet_kill on device open/remove, and use
tasklet_disable/tasklet_enable on device suspend/resume.

When the firmware is in SNIFFER mode, it leaves
the FCS at the end of frame. Not telling mac80211
means it won't add the right flag to the radiotap
header and that confuses wireshark.
Since mac80211 doesn't have a per-packet flag, set
the HW flag dynamically. This works as the monitor
vif can only be present in the driver by itself.

This change fixes an issue I found where VXLAN frames were fragmented when
they were up to the VXLAN MTU size. I root caused the issue to the fact that
the headroom was 4 + 20 + 8 + 8. This math doesn't appear to be correct
because we are not inserting a VLAN header, but instead a 2nd Ethernet header.
As such the math for the overhead should be 20 + 8 + 8 + 14 to account for the
extra headers that are inserted for VXLAN.

A number of Huawei 3G and LTE modems implement a CDC NCM function,
including the necessary functional descriptors, but using a non
standard interface layout and class/subclass/protocol codes.
These devices can be handled by this driver with only a minor
change to the probing logic, allowing a single combined control
and data interface. This works because the devices
- include a CDC Union descriptor labelling the combined
interface as both master and slave, and
- have an alternate setting #1 for the bulk endpoints on the
combined interface.
The 3G/LTE network connection is managed by vendor specific AT
commands on a serial function in the same composite device.
Handling the managment function is out of the scope of this
driver. It will be handled by an appropriate USB serial
driver.

If a gianfar ethernet device is down prior to hibernating a
system, it will no longer be present upon system restore.
For example:
~# ifconfig eth0 down
~# echo disk > /sys/power/state
<trigger a restore from hibernation>
~# ifconfig eth0 up
SIOCSIFFLAGS: No such device
This happens because the restore function bails out early upon
finding devices that were not up at hibernation. In doing so,
it never gets to the netif_device_attach call at the end of
the restore function. Adding the netif_device_attach as done
here also makes the gfar_restore code consistent with what is
done in the gfar_resume code.

INGPADBOUNDARY_MASK is already shifted. No need to shift it again. On reloading
a driver it was resulting in a bad SGE FL MTU sizes [1536, 9088] error. This
only causes an issue on systems that have L1 cache size of 32B, 128B, 512B,
2048B or 4096B.
