A few drivers use dev_uc_sync/unsync to synchronize the
address lists from master down to slave/lower devices.  In
some cases (bond/team) a single address list is synched down
to multiple devices.  At the time of unsync, we have a leak
in these lower devices, because "synced" is treated as a
boolean and the address will not be unsynced for anything after
the first device/call.

Treat "synced" as a count (same as refcount) and allow all
unsync calls to work.

John W. Linville says:

====================
Here are some more fixes intended for the 3.9 stream...

Regarding the mac80211 bits, Johannes says:

"I had changed the idle handling to simplify it, but broken the
sequencing of commands, at least for ath9k-htc, one patch restores the
sequence. The other patch fixes a crash Jouni found while stress-testing
the remain-on-channel code, when an item is deleted the work struct can
run twice and crash the second time."

As for the iwlwifi bits, Johannes says:

"The only fix here is to the passive-no-RX firmware regulatory
enforcement driver support code to not drop auth frames in quick
succession, leading to not being able to connect to APs on passive
channels in certain circumstances."

Don't forget the NFC bits, about which Samuel says:

"This time we have:

- A crash fix for when a DGRAM LLCP socket is listening while the NFC adapter
  is physically removed.
- A potential double skb free when the LLCP socket receive queue is full.
- A fix for properly handling multiple and consecutive LLCP connections, and
  not trash the socket ack log.
- A build failure for the MEI microread physical layer, now that the MEI bus
  APIs have been merged into char-misc-next."

On top of that, Stone Piao provides an mwifiex fix to avoid accessing
beyond the end of a buffer.

The VMCI context ID of a virtual machine may change at any time. There
is a VMCI event which signals this but datagrams may be processed before
this is handled. It is therefore necessary to be flexible about the
destination context ID of any datagrams received. (It can be assumed to
be correct because it is provided by the hypervisor.) The context ID on
existing sockets should be updated to reflect how the hypervisor is
currently referring to the system.

IPv6 Routing table becomes broken once we do ifdown, ifup of the loopback(lo)
interface. After down-up, routes of other interface's IPv6 addresses through
'lo' are lost.

IPv6 addresses assigned to all interfaces are routed through 'lo' for internal
communication. Once 'lo' is down, those routing entries are removed from routing
table. But those removed entries are not being re-created properly when 'lo' is
brought up. So IPv6 addresses of other interfaces becomes unreachable from the
same machine. Also this breaks communication with other machines because of
NDISC packet processing failure.

This patch fixes this issue by reading all interface's IPv6 addresses and adding
them to IPv6 routing table while bringing up 'lo'.

currently cbq works incorrectly for limits > 10% real link bandwidth,
and practically does not work for limits > 50% real link bandwidth.
Below are results of experiments taken on 1 Gbit link

 In shaper | Actual Result
-----------+---------------
  100M     | 108 Mbps
  200M     | 244 Mbps
  300M     | 412 Mbps
  500M     | 893 Mbps

This happen because of q->now changes incorrectly in cbq_dequeue():
when it is called before real end of packet transmitting,
L2T is greater than real time delay, q_now gets an extra boost
but never compensate it.

To fix this problem we prevent change of q->now until its synchronization
with real time.

struct block_device lifecycle is defined by its inode (see fs/block_dev.c) -
block_device allocated first time we access /dev/loopXX and deallocated on
bdev_destroy_inode. When we create the device "losetup /dev/loopXX afile"
we want that block_device stay alive until we destroy the loop device
with "losetup -d".

But because we do not hold /dev/loopXX inode its counter goes 0, and
inode/bdev can be destroyed at any moment. Usually it happens at memory
pressure or when user drops inode cache (like in the test below). When later in
loop_clr_fd() we want to use bdev we have use-after-free error with following
stack:

BUG: unable to handle kernel NULL pointer dereference at 0000000000000280

  compat_sys_ioctl+0xc1/0xf20
  do_sys_open+0x16e/0x1d0
  sysenter_dispatch+0x7/0x1a

To prevent use-after-free we need to grab the device in loop_set_fd()
and put it later in loop_clr_fd().

The issue is reprodusible on current Linus head and v3.3. Here is the test:

  dd if=/dev/zero of=loop.file bs=1M count=1
  while [ true ]; do
    losetup /dev/loop0 loop.file
    echo 2 > /proc/sys/vm/drop_caches
    losetup -d /dev/loop0
  done

[ Doing bdgrab/bput in loop_set_fd/loop_clr_fd is safe, because every
  time we call loop_set_fd() we check that loop_device->lo_state is
  Lo_unbound and set it to Lo_bound If somebody will try to set_fd again
  it will get EBUSY.  And if we try to loop_clr_fd() on unbound loop
  device we'll get ENXIO.

  loop_set_fd/loop_clr_fd (and any other loop ioctl) is called under
  loop_device->lo_ctl_mutex. ]

Samuel Ortiz <sameo@linux.intel.com> says:

"This is the 2nd batch of NFC fixes for 3.9. This time we have:

- A crash fix for when a DGRAM LLCP socket is listening while the NFC adapter
  is physically removed.
- A potential double skb free when the LLCP socket receive queue is full.
- A fix for properly handling multiple and consecutive LLCP connections, and
  not trash the socket ack log.
- A build failure for the MEI microread physical layer, now that the MEI bus
  APIs have been merged into char-misc-next."

Under some circumstances the PLLE needs to be retrained, in which case
access to the PMC registers is required. Fix this by passing a pointer
to the PMC registers instead of NULL when registering the PLLE clock.

    Fix from Eric Dumazet.

15) RX overflow happens too quickly in sky2 driver because pause packet
    thresholds are not programmed correctly.  From Mirko Lindner.

16) Bonding driver manages arp_interval and miimon settings incorrectly,
    disabling one unintentionally disables both.  Fix from Nikolay
    Aleksandrov.

    crashes in bonding driver unload stress tests.  From Eric Dumazet.

21) rxlen field of ks8851 RX packet descriptors not interpreted
    correctly (it is 12 bits not 16 bits, so needs to be masked after
    shifting the 32-bit value down 16 bits).  Fix from Max Nekludov.

22) Fix missed RX/TX enable in sh_eth driver due to mishandling of link
    change indications.  From Sergei Shtylyov.

Fix bug for DM9000 revision B which contain a DSP PHY

DM9000B use DSP PHY instead previouse DM9000 revisions' analog PHY,
So need extra change in initialization, For
explicity PHY Reset and PHY init parameter, and
first DM9000_NCR reset need NCR_MAC_LBK bit by dm9000_probe().

Following DM9000_NCR reset cause by dm9000_open() clear the
NCR_MAC_LBK bit.

rate among Davicom's customers' boards. With this fix, All above

The 'link' field of 'struct sh_eth_private' has type 'enum phy_state' while the
'link' field of 'struct phy_device' is merely *int* (having values 0 and 1) and
the former field gets assigned from the latter. Make the field match, getting
rid of incorrectly used PHY_DOWN value in assignments/comparisons.

At least on Renesas R8A7778, EESR.ECI interrupt seems to fire regardless of its
mask in EESIPR register. I can 100% reproduce it with the following scenario:
target is booted with 'ip=on' option, and so IP-Config opens SoC Ether device
but doesn't get a proper reply and then succeeds with on-board SMC chip; then
I login and try to bring up the SoC Ether device with 'ifconfig', and I get
an ECI interrupt once request_irq() is called by sh_eth_open() (while interrupt
mask in EESIPR register is all 0), if that interrupt is accompanied by a pending
EESR.FRC (frame receive completion) interrupt, I get kernel oops in sh_eth_rx()
because sh_eth_ring_init() hasn't been called yet!

The solution I worked out is the following: in sh_eth_interrupt(), mask the
interrupt status from EESR register with the interrupt mask from EESIPR register
in order not to handle the disabled interrupts -- but forcing EESIPR.M_ECI bit
in this mask set because we always need to fully handle EESR.ECI interrupt in
sh_eth_error() in order to quench it (as it doesn't get cleared by just writing
1 to the this bit as all the other interrupts).

While at it, remove unneeded initializer for 'intr_status' variable and give it
*unsigned long* type, matching the type of sh_eth_read()'s result; fix comment.

The code handling the absent LINK signal (or the absent PSR register -- which
reflects the state of this signal) is quite naive and has probably never really
worked.  It's probably enough to say that this code is executed only on the LINK
change interrupt (sic!) but even if we actually have the signal and choose to
ignore it (it might be connected to PHY's link/activity LED output as on the
Renesas BOCK-W board), sh_eth_adjust_link() on which this code relies to update
'mdp->link' gets executed later than the LINK change interrupt where it is
checked, and so RX/TX never get enabled via ECMR register.

So, ignore the LINK changed interrupt iff LINK signal is absent (or just chosen
not to be used) or PSR register is absent, and enable/disable RX/TX directly in
sh_eth_adjust_link() in this case.
