Currently macvlan will count received packets after calling each
vlans receive handler. Macvtap attempts to count the packet
yet again when the user reads the packet from the tap socket.
This code doesn't do this consistently either. Remove the
counting from macvtap and let only macvlan count received
packets.

2fdac010bd ("via-velocity.c: update napi
implementation") overlooked an irq disabling spinlock when the Rx part
of the NAPI poll handler was converted from netif_rx to netif_receive_skb.
NAPI Rx processing can be taken out of the locked section with a pair of
napi_{disable / enable} since it only races with the MTU change function.
An heavier rework of the NAPI locking would be able to perform NAPI Tx
before Rx where I simply removed one of velocity_tx_srv calls.

The pmcraid driver is abusing the genetlink API and is using its
family ID as the multicast group ID, which is invalid and may
belong to somebody else (and likely will.)
Make it use the correct API, but since this may already be used
as-is by userspace, reserve a family ID for this code and also
reserve that group ID to not break userspace assumptions.
My previous patch broke event delivery in the driver as I missed
that it wasn't using the right API and forgot to update it later
in my series.
While changing this, I noticed that the genetlink code could use
the static group ID instead of a strcmp(), so also do that for
the VFS_DQUOT family.

Because the ARP monitoring is not support for 802.3ad, but I still
could change the mode to 802.3ad from ab mode while ARP monitoring
is running, it is incorrect.
So add a check for 802.3ad in bonding_store_mode to fix the problem,
and make a new macro BOND_NO_USES_ARP() to simplify the code.
v2: according to the Dan Williams's suggestion, bond mode is the most
important bond option, it should override any of the other sub-options.
So when the mode is changed, the conficting values should be cleared
or reset, otherwise the user has to duplicate more operations to modify
the logic. I disable the arp and enable mii monitoring when the bond mode
is changed to AB, TB and 8023AD if the arp interval is true.
v3: according to the Nik's suggestion, the default value of miimon should need
a name, there is several place to use it, and the bond_store_arp_interval()
could use micro BOND_NO_USES_ARP to make the code more simpify.

This patch now always passes msg->msg_namelen as 0. recvmsg handlers must
set msg_namelen to the proper size <= sizeof(struct sockaddr_storage)
to return msg_name to the user.
This prevents numerous uninitialized memory leaks we had in the
recvmsg handlers and makes it harder for new code to accidentally leak
uninitialized memory.
Optimize for the case recvfrom is called with NULL as address. We don't
need to copy the address at all, so set it to NULL before invoking the
recvmsg handler. We can do so, because all the recvmsg handlers must
cope with the case a plain read() is called on them. read() also sets
msg_name to NULL.
Also document these changes in include/linux/net.h as suggested by David
Miller.
Changes since RFC:
Set msg->msg_name = NULL if user specified a NULL in msg_name but had a
non-null msg_namelen in verify_iovec/verify_compat_iovec. This doesn't
affect sendto as it would bail out earlier while trying to copy-in the
address. It also more naturally reflects the logic by the callers of
verify_iovec.
With this change in place I could remove "
if (!uaddr || msg_sys->msg_namelen == 0)
msg->msg_name = NULL
".
This change does not alter the user visible error logic as we ignore
msg_namelen as long as msg_name is NULL.
Also remove two unnecessary curly brackets in ___sys_recvmsg and change
comments to netdev style.

The tx/rx would access the memory which is out of the desired range.
Modify the method of checking the end of the memory to avoid it.
For r8152_tx_agg_fill(), the variable remain may become negative.
However, the declaration is unsigned, so the while loop wouldn't
break when reaching the end of the desied memory. Although to change
the declaration from unsigned to signed is enough to fix it, I also
modify the checking method for safe. Replace
remain = rx_buf_sz - sizeof(*tx_desc) -
(u32)((void *)tx_data - agg->head);
with
remain = rx_buf_sz - (int)(tx_agg_align(tx_data) - agg->head);
to make sure the variable remain is always positive. Then, the
overflow wouldn't happen.
For rx_bottom(), the rx_desc should not be used to calculate the
packet length before making sure the rx_desc is in the desired range.
Change the checking to two parts. First, check the descriptor is in
the memory. The other, using the descriptor to find out the packet
length and check if the packet is in the memory.

It appears that driver runs into a problem here if fibsize is too small
because we allocate user_srbcmd with fibsize size only but later we
access it until user_srbcmd->sg.count to copy it over to srbcmd.
It is not correct to test (fibsize < sizeof(*user_srbcmd)) because this
structure already includes one sg element and this is not needed for
commands without data. So, we would recommend to add the following
(instead of test for fibsize == 0).

Pull networking fixes from David Miller:
"Mostly these are fixes for fallout due to merge window changes, as
well as cures for problems that have been with us for a much longer
period of time"
1) Johannes Berg noticed two major deficiencies in our genetlink
registration. Some genetlink protocols we passing in constant
counts for their ops array rather than something like
ARRAY_SIZE(ops) or similar. Also, some genetlink protocols were
using fixed IDs for their multicast groups.
We have to retain these fixed IDs to keep existing userland tools
working, but reserve them so that other multicast groups used by
other protocols can not possibly conflict.
In dealing with these two problems, we actually now use less state
management for genetlink operations and multicast groups.
2) When configuring interface hardware timestamping, fix several
drivers that simply do not validate that the hwtstamp_config value
is one the driver actually supports. From Ben Hutchings.
3) Invalid memory references in mwifiex driver, from Amitkumar Karwar.
4) In dev_forward_skb(), set the skb->protocol in the right order
relative to skb_scrub_packet(). From Alexei Starovoitov.
5) Bridge erroneously fails to use the proper wrapper functions to make
calls to netdev_ops->ndo_vlan_rx_{add,kill}_vid. Fix from Toshiaki
Makita.
6) When detaching a bridge port, make sure to flush all VLAN IDs to
prevent them from leaking, also from Toshiaki Makita.
7) Put in a compromise for TCP Small Queues so that deep queued devices
that delay TX reclaim non-trivially don't have such a performance
decrease. One particularly problematic area is 802.11 AMPDU in
wireless. From Eric Dumazet.
8) Fix crashes in tcp_fastopen_cache_get(), we can see NULL socket dsts
here. Fix from Eric Dumzaet, reported by Dave Jones.

Register generic netlink multicast groups as an array with
the family and give them contiguous group IDs. Then instead
of passing the global group ID to the various functions that
send messages, pass the ID relative to the family - for most
families that's just 0 because the only have one group.
This avoids the list_head and ID in each group, adding a new
field for the mcast group ID offset to the family.
At the same time, this allows us to prevent abusing groups
again like the quota and dropmon code did, since we can now
check that a family only uses a group it owns.

As suggested by David Miller, make genl_register_family_with_ops()

The openvswitch has some indirection, assing ops/n_ops directly in

Pull media build fixes from Mauro Carvalho Chehab:
"A series of patches that fix compilation on non-x86 archs.
While most of them are just build fixes, there are some fixes for real
bugs, as there are a number of drivers using dynamic stack allocation.
A few of those might be considered a security risk, if the i2c-dev
module is loaded, as someone could be sending very long I2C data that
could potentially overflow the Kernel stack. Ok, as using /dev/i2c-*
devnodes usually requires root on usual distros, and exploiting it
would require a DVB board or USB stick, the risk is not high"

Pull media updates from Mauro Carvalho Chehab:
"This series include:
- a new Remote Controller driver for ST SoC with the corresponding DT
bindings
- a new frontend (cx24117)
- a new I2C camera flash driver (lm3560)
- a new mem2mem driver for TI SoC (ti-vpe)
- support for Raphael r828d added to r820t driver
- some improvements on buffer allocation at VB2 core
- usual driver fixes and improvements
PS this time, we have a smaller number of patches. While it is hard
to pinpoint to the reasons, I believe that it is mainly due to:
1) there are several patch series ready, but depending on DT review.
I decided to grant some extra time for DT maintainers to look on
it, as they're expecting to have more time with the changes agreed
during ARM mini-summit and KS. If they can't review in time for
3.14, I'll review myself and apply for the next merge window.
2) I suspect that having both LinuxCon EU and LinuxCon NA happening
during the same merge window affected the development
productivity, as several core media developers participated on
both events"

Pull EDAC updates from Borislav Petkov:
"Following up on last week's discussion, here's my part of the EDAC
pile, highlights in the signed tag.
The last two patches have a date from just now because I've just
applied them to the tree after Johannes sent them to me earlier. I
decided to forward them now because they're trivial.
There's a third one for MPC85xx which adds PCIe error interrupt
support but since it is not so trivial and hasn't seen any linux-next
time, I'm deferring it to 3.14
EDAC update highlights:
- Support for Calxeda ECX-2000 memory controller, from Robert Richter
- Misc Calxeda Highbank drivers and EDAC core cleanups, from Rob
Herring and Robert Richter
- New maintainer for Freescale's MPC85xx EDAC driver: Johannes

Secondary unicast MAC addresses will get deleted only when the interface is UP.
When the interface is DOWN, though these secondary MAC addresses are unusable
and awaiting to be deleted, cause the firmware to believe that they are being used.
If the user intends to set a MAC address as primary MAC from one of these
secondary MAC addresses, the firmware returns a MAC address Collision error.
Delete these secondary MAC addresses during be_close.
The secondary MAC addresses list will be refreshed during interface open anyway.

The driver currently requests the firmware to enable rx_interface options
without considering if the interface was created with that capability.
This could cause commands to firmware to fail.
To avoid this, enable only those options on an interface if the interface
was created with that capability.
