pch_gbe: Fix the MAC Address load issue.
With the specification of hardware,
the processing at the time of driver starting was modified.
This device write automatically the MAC address read from serial ROM
into a MAC Adress1A/1B register at the time of power on reset.
However, when stable clock is not supplied,
the writing of MAC Adress1A/1B register may not be completed.
In this case, it is necessary to load MAC address to MAC Address1A/1B register
by the MAC Address1 load register.
This patch always does the above processing,
in order not to be dependent on system environment.

Net, USB, Option, hso: Do not dereference NULL pointer

code:
...
serial = kzalloc(sizeof(*serial), GFP_KERNEL);
if (!serial)
goto exit;
...
exit:
hso_free_tiomget(serial);
...
hso_free_tiomget() directly dereferences its argument, which in the
example above is a NULL pointer, ouch.
I could just add a 'if (serial)' test at the 'exit' label, but since most
freeing functions in the kernel accept NULL pointers (and it seems like
this was also assumed here) I opted to instead change 'hso_free_tiomget()'
so that it is safe to call it with a NULL argument. I also modified the
function to get rid of a pointles conditional before the call to
'usb_free_urb()' since that function already tests for NULL itself -
besides fixing the NULL deref this change also buys us a few bytes in
size.

bridge: Fix mglist corruption that leads to memory corruption
The list mp->mglist is used to indicate whether a multicast group
is active on the bridge interface itself as opposed to one of the
constituent interfaces in the bridge.
Unfortunately the operation that adds the mp->mglist node to the
list neglected to check whether it has already been added. This
leads to list corruption in the form of nodes pointing to itself.
Normally this would be quite obvious as it would cause an infinite
loop when walking the list. However, as this list is never actually
walked (which means that we don't really need it, I'll get rid of
it in a subsequent patch), this instead is hidden until we perform
a delete operation on the affected nodes.
As the same node may now be pointed to by more than one node, the
delete operations can then cause modification of freed memory.
This was observed in practice to cause corruption in 512-byte slabs,
most commonly leading to crashes in jbd2.
Thanks to Josef Bacik for pointing me in the right direction.

net: Fix lockdep regression caused by initializing netdev queues too early.
In commit
aa9421041128abb4d269ee1dc502ff65fb3b7d69 ("net: init ingress
queue") we moved the allocation and lock initialization of the queues
into alloc_netdev_mq() since register_netdevice() is way too late.
The problem is that dev->type is not setup until the setup()
callback is invoked by alloc_netdev_mq(), and the dev->type is
what determines the lockdep class to use for the locks in the
queues.
Fix this by doing the queue allocation after the setup() callback
runs.
This is safe because the setup() callback is not allowed to make any
state changes that need to be undone on error (memory allocations,
etc.). It may, however, make state changes that are undone by
free_netdev() (such as netif_napi_add(), which is done by the
ipoib driver's setup routine).
The previous code also leaked a reference to the &init_net namespace
object on RX/TX queue allocation failures.

rtnl_link_ops->setup(), and the "setup" callback passed to alloc_netdev*(),

So we have to add the caif private instance to the global list once we

Otherwise, if register_netdev() fails, the caller will invoke free_netdev()
and we will have a reference to freed up memory on the chnl_net_list.

niu: Fix races between up/down and get_stats.
As reported by Flavio Leitner, there is no synchronization to protect
NIU's get_stats method from seeing a NULL pointer in either
np->rx_rings or np->tx_rings. In fact, as far as ->ndo_get_stats
is concerned, these values are set completely asynchronously.
Flavio attempted to fix this using a RW semaphore, which in fact
works most of the time. However, dev_get_stats() can be invoked
from non-sleepable contexts in some cases, so this fix doesn't
work in all cases.
So instead, control the visibility of the np->{rx,tx}_ring pointers
when the device is being brough up, and use properties of the device
down sequence to our advantage.
In niu_get_stats(), return immediately if netif_running() is false.
The device shutdown sequence first marks the device as not running (by
clearing the __LINK_STATE_START bit), then it performans a
synchronize_rcu() (in dev_deactive_many()), and then finally it
invokes the driver ->ndo_stop() method.
This guarentees that all invocations of niu_get_stats() either see
netif_running() as false, or they see the channel pointers before
->ndo_stop() clears them out.
If netif_running() is true, protect against startup races by loading
the np->{rx,tx}_rings pointer into a local variable, and punting if
it is NULL. Use ACCESS_ONCE to prevent the compiler from reloading
the pointer on us.
Also, during open, control the order in which the pointers and the
ring counts become visible globally using SMP write memory barriers.
We make sure the np->num_{rx,tx}_rings value is stable and visible
before np->{rx,tx}_rings is.
Such visibility control is not necessary on the niu_free_channels()
side because of the RCU sequencing that happens during device down as
described above. We are always guarenteed that all niu_get_stats
calls are finished, or will see netif_running() false, by the time
->ndo_stop is invoked.
