Add support for the independent control state machine per IEEE
802.1AX-2008 5.4.15 in addition to the existing implementation of the
coupled control state machine.
Introduces two new states, AD_MUX_COLLECTING and AD_MUX_DISTRIBUTING in
the LACP MUX state machine for separated handling of an initial
Collecting state before the Collecting and Distributing state. This
enables a port to be in a state where it can receive incoming packets
while not still distributing. This is useful for reducing packet loss when
a port begins distributing before its partner is able to collect.
Added new functions such as bond_set_slave_tx_disabled_flags and
bond_set_slave_rx_enabled_flags to precisely manage the port's collecting
and distributing states. Previously, there was no dedicated method to
disable TX while keeping RX enabled, which this patch addresses.
Note that the regular flow process in the kernel's bonding driver remains
unaffected by this patch. The extension requires explicit opt-in by the
user (in order to ensure no disruptions for existing setups) via netlink
support using the new bonding parameter coupled_control. The default value
for coupled_control is set to 1 so as to preserve existing behaviour.

struct nla_policy is usually constant itself, but unless
we make the ranges inside constant we won't be able to
make range structs const. The ranges are not modified
by the core.

Bonding send_peer_notif was defined as u8. Since commit 07a4ddec3ce9
("bonding: add an option to specify a delay between peer notifications").
the bond->send_peer_notif will be num_peer_notif multiplied by
peer_notif_delay, which is u8 * u32. This would cause the send_peer_notif
overflow easily. e.g.
ip link add bond0 type bond mode 1 miimon 100 num_grat_arp 30 peer_notify_delay 1000
To fix the overflow, let's set the send_peer_notif to u32 and limit
peer_notif_delay to 300s.

Add per port priority support for bonding active slave re-selection during
failover. A higher number means higher priority in selection. The primary
slave still has the highest priority. This option also follows the
primary_reselect rules.
This option could only be configured via netlink.

Add support for reporting errors via extack in both bond_newlink
and bond_changelink.
Instead of having to look in the kernel log for why an option was not
correct just report the error to the user via the extack variable.
What is currently reported today:
ip link add bond0 type bond
ip link set bond0 up
ip link set bond0 type bond mode 4
RTNETLINK answers: Device or resource busy
After this change:
ip link add bond0 type bond
ip link set bond0 up
ip link set bond0 type bond mode 4
Error: unable to set option because the bond is up.

When setting bond NS target, we use bond_is_ip6_target_ok() to check
if the address valid. The link local address was wrongly rejected in
bond_changelink(), as most time the user just set the ARP/NS target to
gateway, while the IPv6 gateway is always a link local address when user
set up interface via SLAAC.
So remove the link local addr check when setting bond NS target.

This patch add a new bonding option ns_ip6_target, which correspond
to the arp_ip_target. With this we set IPv6 targets and send IPv6 NS
request to determine the health of the link.
For other related options like the validation, we still use
arp_validate, and will change to ns_validate later.

Currently, we use hard code number to verify if we are in the
arp_interval timeslice. But some user may want to reduce/extend
the verify timeslice. With the similar team option 'missed_max'
the uers could change that number based on their own environment.

Add an option lacp_active, which is similar with team's runner.active.
This option specifies whether to send LACPDU frames periodically. If set
on, the LACPDU frames are sent along with the configured lacp_rate
setting. If set off, the LACPDU frames acts as "speak when spoken to".
Note, the LACPDU state frames still will be sent when init or unbind port.

Currently, gratuitous ARP/ND packets are sent every `miimon'
milliseconds. This commit allows a user to specify a custom delay
through a new option, `peer_notif_delay'.
Like for `updelay' and `downdelay', this delay should be a multiple of
`miimon' to avoid managing an additional work queue. The configuration
logic is copied from `updelay' and `downdelay'. However, the default
value cannot be set using a module parameter: Netlink or sysfs should
be used to configure this feature.
When setting `miimon' to 100 and `peer_notif_delay' to 500, we can
observe the 500 ms delay is respected:
20:30:19.354693 ARP, Request who-has 203.0.113.10 tell 203.0.113.10, length 28
20:30:19.874892 ARP, Request who-has 203.0.113.10 tell 203.0.113.10, length 28
20:30:20.394919 ARP, Request who-has 203.0.113.10 tell 203.0.113.10, length 28
20:30:20.914963 ARP, Request who-has 203.0.113.10 tell 203.0.113.10, length 28
In bond_mii_monitor(), I have tried to keep the lock logic readable.
The change is due to the fact we cannot rely on a notification to
lower the value of `bond->send_peer_notif' as `NETDEV_NOTIFY_PEERS' is
only triggered once every N times, while we need to decrement the
counter each time.
iproute2 also needs to be updated to be able to specify this new
attribute through `ip link'.

Even if the NLA_F_NESTED flag was introduced more than 11 years ago, most
netlink based interfaces (including recently added ones) are still not
setting it in kernel generated messages. Without the flag, message parsers
not aware of attribute semantics (e.g. wireshark dissector or libmnl's
mnl_nlmsg_fprintf()) cannot recognize nested attributes and won't display
the structure of their contents.
Unfortunately we cannot just add the flag everywhere as there may be
userspace applications which check nlattr::nla_type directly rather than
through a helper masking out the flags. Therefore the patch renames
nla_nest_start() to nla_nest_start_noflag() and introduces nla_nest_start()
as a wrapper adding NLA_F_NESTED. The calls which add NLA_F_NESTED manually
are rewritten to use nla_nest_start().
Except for changes in include/net/netlink.h, the patch was generated using
this semantic patch:
@@ expression E1, E2; @@
-nla_nest_start(E1, E2)
+nla_nest_start_noflag(E1, E2)
@@ expression E1, E2; @@

This patch adds support for extended statistics (xstats) call to the
bonding. The first user would be the 3ad code which counts the following
events:
- LACPDU Rx/Tx
- LACPDU unknown type Rx
- LACPDU illegal Rx
- Marker Rx/Tx
- Marker response Rx/Tx
- Marker unknown type Rx
All of these are exported via netlink as separate attributes to be
easily extensible as we plan to add more in the future.
Similar to how the bridge and other xstats exports, the structure
inside is:
[ IFLA_STATS_LINK_XSTATS ]
-> [ LINK_XSTATS_TYPE_BOND ]
-> [ BOND_XSTATS_3AD ]
-> [ 3ad stats attributes ]
With this structure it's easy to add more stat types later.

Earlier patch 4493b81bea ("bonding: initialize work-queues during
creation of bond") moved the work-queue initialization from bond_open()
to bond_create(). However this caused the link those are created using
netlink 'create bond option' (ip link add bondX type bond); create the
new trunk without initializing work-queues. Prior to the above mentioned
change, ndo_open was in both paths and things worked correctly. The
consequence is visible in the report shared by Joe Stringer -
I've noticed that this patch breaks bonding within namespaces if
you're not careful to perform device cleanup correctly.
Here's my repro script, you can run on any net-next with this patch
and you'll start seeing some weird behaviour:
ip netns add foo
ip li add veth0 type veth peer name veth0+ netns foo
ip li add veth1 type veth peer name veth1+ netns foo
ip netns exec foo ip li add bond0 type bond
ip netns exec foo ip li set dev veth0+ master bond0
ip netns exec foo ip li set dev veth1+ master bond0
ip netns exec foo ip addr add dev bond0 192.168.0.1/24
ip netns exec foo ip li set dev bond0 up
ip li del dev veth0
ip li del dev veth1
The second to last command segfaults, last command hangs. rtnl is now
permanently locked. It's not a problem if you take bond0 down before
deleting veths, or delete bond0 before deleting veths. If you delete
either end of the veth pair as per above, either inside or outside the
namespace, it hits this problem.
Here's some kernel logs:
[ 1221.801610] bond0: Enslaving veth0+ as an active interface with an up link
[ 1224.449581] bond0: Enslaving veth1+ as an active interface with an up link

Commit e826eafa65c6 ("bonding: Call netif_carrier_off after
register_netdevice") moved netif_carrier_off() from bond_init() to
bond_create(), but the latter is called only for initial default
devices and ones created through sysfs:
$ modprobe bonding
$ echo +bond1 > /sys/class/net/bonding_masters
$ ip link add bond2 type bond
$ grep "MII Status" /proc/net/bonding/*
/proc/net/bonding/bond0:MII Status: down
/proc/net/bonding/bond1:MII Status: down
/proc/net/bonding/bond2:MII Status: up
Ensure that carrier is initially off also for devices created through
netlink.

Actor and Partner details can be accessed via proc-fs, sys-fs
entries or netlink interface. These interfaces are world readable
at this moment. The earlier patch-series made the LACP communication
secure to avoid nuisance attack from within the same L2 domain but
it did not prevent "someone unprivileged" looking at that information
on host and perform the same act.
This patch essentially avoids spitting those entries if the user
in question does not have enough privileges.

Adds netlink support for the following bonding options:
* BOND_OPT_AD_ACTOR_SYS_PRIO
* BOND_OPT_AD_ACTOR_SYSTEM
* BOND_OPT_AD_USER_PORT_KEY
When setting the actor system mac address we assume the netlink message
contains a binary mac and not a string representation of a mac.

This patch adds support for slave_changelink to the bonding and uses it
to give the ability to change the queue_id of the enslaved devices via
netlink. It sets slave_maxtype and uses bond_changelink as a prototype for
bond_slave_changelink.
Example/test command after the iproute2 patch:
ip link set eth0 type bond_slave queue_id 10

The struct ad_slave_info is very huge, and only be used for 802.3ad mode,
so alloc the structure dynamically could save 356 Bits for every slave in
