Conflicts:
drivers/net/wireless/ath/ath9k/recv.c
drivers/net/wireless/mwifiex/pcie.c
net/ipv6/sit.c
The SIT driver conflict consists of a bug fix being done by hand
in 'net' (missing u64_stats_init()) whilst in 'net-next' a helper
was created (netdev_alloc_pcpu_stats()) which takes care of this.
The two wireless conflicts were overlapping changes.

Currently we're only sending arp requests if we have a route to the target
(and, thus, can find out the source ip address).
There are some use cases, however, where we don't want/need to set an ip
address (or set up a specific route) for bonding to use arp monitoring *for
traffic generation*. We can easily send arp probes (arp requests with src
ip == 0) to generate arp broadcast responses from the target ip and use
them for determining if the target is up.
This, obviously, won't work with arp validation - because we don't have the
ip address set and, thus, will filter out the responses. So in that case -
print a warning.

There's a bug in the slave release function which leads the transmit
functions which use the bond->slave_cnt to a div by 0 because we might
just have released our last slave and made slave_cnt == 0 but at the same
time we may have a transmitter after the check for an empty list which will
fetch it and use it in the slave id calculation.
Fix it by moving the slave_cnt after synchronize_rcu so if this was our
last slave any new transmitters will see an empty slave list which is
checked after rcu lock but before calling the mode transmit functions
which rely on bond->slave_cnt.

Veaceslav has reported and fix this problem by commit f2ebd477f141bc0
(bonding: restructure locking of bond_ab_arp_probe()). According Jay's
opinion, the current solution is not very well, because the notification
is to indicate that the interface has actually changed state in a meaningful
way, but these calls in the ab ARP monitor are internal settings of the flags
to allow the ARP monitor to search for a slave to become active when there are
no active slaves. The flag setting to active or backup is to permit the ARP
monitor's response logic to do the right thing when deciding if the test
slave (current_arp_slave) is up or not.
So the best way to fix the problem is that we should not send a notification
when the slave is in testing state, and check the state at the end of the
monitor, if the slave's state recover, avoid to send pointless notification
twice. And RTNL is really a big lock, hold it regardless the slave's state
changed or not when the current_active_slave is null will loss performance
(every 100ms), so we should hold it only when the slave's state changed and
need to notify.
I revert the old commit and add new modifications.

The problem was introduced by the commit 1d3ee88ae0d
(bonding: add netlink attributes to slave link dev).
The bond_set_active_slave() and bond_set_backup_slave()
will use rtmsg_ifinfo to send slave's states, so these
two functions should be called in RTNL.
In 802.3ad mode, acquiring RTNL for the __enable_port and
__disable_port cases is difficult, as those calls generally
already hold the state machine lock, and cannot unconditionally
call rtnl_lock because either they already hold RTNL (for calls
via bond_3ad_unbind_slave) or due to the potential for deadlock
with bond_3ad_adapter_speed_changed, bond_3ad_adapter_duplex_changed,
bond_3ad_link_change, or bond_3ad_update_lacp_rate. All four of
those are called with RTNL held, and acquire the state machine lock
second. The calling contexts for __enable_port and __disable_port
already hold the state machine lock, and may or may not need RTNL.
According to the Jay's opinion, I don't think it is a problem that
the slave don't send notify message synchronously when the status
changed, normally the state machine is running every 100 ms, send
the notify message at the end of the state machine if the slave's
state changed should be better.
I fix the problem through these steps:
1). add a new function bond_set_slave_state() which could change
the slave's state and call rtmsg_ifinfo() according to the input
parameters called notify.
2). Add a new slave parameter which called should_notify, if the slave's state
changed and don't notify yet, the parameter will be set to 1, and then if
the slave's state changed again, the param will be set to 0, it indicate that
the slave's state has been restored, no need to notify any one.
3). the __enable_port and __disable_port should not call rtmsg_ifinfo
in the state machine lock, any change in the state of slave could
set a flag in the slave, it will indicated that an rtmsg_ifinfo
should be called at the end of the state machine.

bond->curr_active_slave can be changed between its deferences, even to
NULL, and thus we might panic.
We're always holding the rcu (rx_handler->bond_handle_frame()->bond_arp_rcv())
so fix this by rcu_dereferencing() it and using the saved.

Currently we only set bond_arp_rcv() if we're using arp_validate, however
this makes us skip updating last_arp_rx if we're not validating incoming
ARPs - thus, if arp_validate is off, last_arp_rx will never be updated.
Fix this by always setting up recv_probe = bond_arp_rcv, even if we're not
using arp_validate.

only validated ARPs.
Fix this by updating it in case of any packet received. It won't break the
arp_validation=0 because we, anyway, return the correct slave->dev->last_rx in

Currently it's disabled because it's sometimes hard, in typical configs, to
make it work - because of the nature how the loadbalance modes work - as
it's hard to deliver valid arp replies to correct slaves by the switch.
However we still can use arp_validation in loadbalance with several other
configs, per example with arp_validate == 2 for backup with one broadcast
domain, without the switch(es) doing any balancing - this way we'd be (a
bit more) sure that the slave is up.
So, enable it to let users decide which one works/suits them best. Also
correct the mode limitation from BOND_OPT_ARP_VALIDATE.

We're always called with rcu_read_lock() held (bond_arp_rcv() is only
called from bond_handle_frame(), which is rx_handler and always called
under rcu from __netif_receive_skb_core() ).
The slave active/passive and/or bonding params can change in-flight, however
we don't really care about that - we only modify the last time packet was
received, which is harmless.

aggregator_identifier is used to assign unique aggregator identifiers
to aggregators of a bond during device enslaving.
aggregator_identifier is currently a global variable that is zeroed in
bond_3ad_initialize().
This sequence will lead to duplicate aggregator identifiers for eth1 and eth3:
create bond0
change bond0 mode to 802.3ad
enslave eth0 to bond0 //eth0 gets agg id 1
enslave eth1 to bond0 //eth1 gets agg id 2
create bond1
change bond1 mode to 802.3ad
enslave eth2 to bond1 //aggregator_identifier is reset to 0
//eth2 gets agg id 1
enslave eth3 to bond0 //eth3 gets agg id 2
Fix this by making aggregator_identifier private to the bond.

Add a new argument for ndo_select_queue() callback that passes a
fallback handler. This gets invoked through netdev_pick_tx();
fallback handler is currently __netdev_pick_tx() as most drivers
invoke this function within their customized implementation in
case for skbs that don't need any special handling. This fallback
handler can then be replaced on other call-sites with different
queue selection methods (e.g. in packet sockets, pktgen etc).
This also has the nice side-effect that __netdev_pick_tx() is
then only invoked from netdev_pick_tx() and export of that
function to modules can be undone.

If the netconsole is in use, the bonding can call printk which puts

So add protection for these place, by checking the netpoll_block_tx

processing
According to bonding.txt, the fail_over_ma should only affect active-backup mode,
but I found that the fail_over_mac could be set to active or follow in all
modes, this will cause new slave could not be set to bond's MAC address at
enslave processing and restore its own MAC address at removal processing.
The correct way to fix the problem is that we should not add restrictions when
setting options, just need to modify the bond enslave and removal processing
to check the mode in addition to fail_over_mac when setting a slave's MAC during
enslavement. The change active slave processing already only calls the fail_over_mac
function when in active-backup mode.
Thanks for Jay's suggestion.

The commit 1d3ee88ae0d605629bf369
(bonding: add netlink attributes to slave link dev)
has add rtmsg_ifinfo() in bond_set_active_slave() and
bond_set_backup_slave(), so the two function need to
called in RTNL lock, but bond_loadbalance_arp_mon()
only calling these functions in RCU, warning message
will occurs.
fix this by add a new function bond_slave_state_change(),
which will reset the slave's state after slave link check,
so remove the bond_set_xxx_slave() from the cycle and only
record the slave_state_changed, this will call the new
function to set all slaves to new state in RTNL later.

After the option conversion downdelay and updelay divide a u64
and on a 32 bit this causes the following errors:
ERROR: "__udivdi3" [drivers/net/bonding/bonding.ko] undefined!
ERROR: "__umoddi3" [drivers/net/bonding/bonding.ko] undefined!
Fix it by using a normal int instead because newval->value is capped
at INT_MAX by the way the option is defined.

Like bridge, bonding as netdevice doesn't cross netns boundaries.
Bonding ports and bonding itself live in same netns.
