In preparation for supporting multiple CPU ports, remove
dst->master_netdev and ds->master_netdev and replace them with only one
instance of the common object we have for a port: struct
dsa_port::netdev. ds->master_netdev is currently write only and would be
helpful in the case where we have two switches, both with CPU ports, and
also connected within each other, which the multi-CPU port patch series
would address.
While at it, introduce a helper function used in net/dsa/slave.c to
immediately get a reference on the master network device called
dsa_master_netdev().

Drivers that initiate roaming while being connected to a network that
uses 802.1X authentication need to inform user space if 802.1X
authentication is further required after roaming.
For example, when using the Fast transition protocol, roaming within
the mobility domain does not require new 802.1X authentication, but
roaming to another mobility domain does.
In addition, some drivers may not support 802.1X authentication
(so it has to be done in user space), while other drivers do.
Add a flag to the roaming notification to indicate if user space is
required to do 802.1X authentication after the roaming or not.
This flag will only be used for networks that use 802.1X
authentication. For networks that do not use 802.1X authentication it
is assumed that no further action is required from user space after
the roaming notification.

Let drivers advertise support for station-mode 4-way handshake
offloading with a new NL80211_EXT_FEATURE_4WAY_HANDSHAKE_STA_PSK flag.
Extend use of NL80211_ATTR_PMK attribute indicating it might be passed
as part of NL80211_CMD_CONNECT command, and contain the PSK (which is
the PMK, hence the name.)
The driver/device is assumed to handle the 4-way handshake by
itself in this case (including key derivations, etc.), instead
of relying on the supplicant.

The ipvlan code already knows how to detect when a duplicate address is
about to be assigned to an ipvlan device. However, that failure is not
propogated outward and leads to a silent failure.
Introduce a validation step at ip address creation time and allow device
drivers to register to validate the incoming ip addresses. The ipvlan
code is the first consumer. If it detects an address in use, we can
return an error to the user before beginning to commit the new ifa in
the networking code.
This can be especially useful if it is necessary to provision many
ipvlans in containers. The provisioning software (or operator) can use
this to detect situations where an ip address is unexpectedly in use.

When a new static FDB is added to the bridge a notification is sent to
the driver for offload. In case of successful offload the driver should
notify the bridge back, which in turn should mark the FDB as offloaded.
Currently, externally learned is equivalent for being offloaded which is
not correct due to the fact that FDBs which are added from user-space are
also marked as externally learned. In order to specify if an FDB was
successfully offloaded a new flag is introduced.

Currently the bridge doesn't notify the underlying devices about new
FDBs learned. The FDB sync is placed on the switchdev notifier chain
because devices may potentially learn FDB that are not directly related
to their ports, for example:
1. Mixed SW/HW bridge - FDBs that point to the ASICs external devices
should be offloaded as CPU traps in order to
perform forwarding in slow path.
2. EVPN - Externally learned FDBs for the vtep device.
Notification is sent only about static FDB add/del. This is done due
to fact that currently this is the only scenario supported by switch
drivers.

This is done as a preparation stage before setting the bridge port flags
from the bridge code. Currently the device can be queried for the bridge
flags state, but the querier cannot distinguish if the flag is disabled
or if it is not supported at all. Thus, add new attr and a bit-mask which
include information regarding the support on a per-flag basis.
Drivers that support bridge offload but not support bridge flags should
return zeroed bitmask.

David Howells says:
====================
rxrpc: Tx length parameter
Here's a set of patches that allows someone initiating a client call with
AF_RXRPC to indicate upfront the total amount of data that will be
transmitted. This will allow AF_RXRPC to encrypt directly from source
buffer to packet rather than having to copy into the buffer and only
encrypt when it's full (the encrypted portion of the packet starts with a
length and so we can't encrypt until we know what the length will be).
The three patches are:
(1) Provide a means of finding out what control message types are actually
supported. EINVAL is reported if an unsupported cmsg type is seen, so
we don't want to set the new cmsg unless we know it will be accepted.
(2) Consolidate some stuff into a struct to reduce the parameter count on
the function that parses the cmsg buffer.
(3) Introduce the RXRPC_TX_LENGTH cmsg. This can be provided on the first
sendmsg() that contributes data to a client call request or a service
call reply. If provided, the user must provide exactly that amount of
data or an error will be incurred.
Changes in version 2:
(*) struct rxrpc_send_params::tx_total_len should be s64 not u64. Thanks to
Julia Lawall for reporting this.

DRAM supply shortage and poor memory pressure tracking in TCP
stack makes any change in SO_SNDBUF/SO_RCVBUF (or equivalent autotuning
limits) and tcp_mem[] quite hazardous.
TCPMemoryPressures SNMP counter is an indication of tcp_mem sysctl
limits being hit, but only tracking number of transitions.
If TCP stack behavior under stress was perfect :
1) It would maintain memory usage close to the limit.
2) Memory pressure state would be entered for short times.
We certainly prefer 100 events lasting 10ms compared to one event
lasting 200 seconds.
This patch adds a new SNMP counter tracking cumulative duration of
memory pressure events, given in ms units.

Provide a control message that can be specified on the first sendmsg() of a
client call or the first sendmsg() of a service response to indicate the
total length of the data to be transmitted for that call.
Currently, because the length of the payload of an encrypted DATA packet is
encrypted in front of the data, the packet cannot be encrypted until we
know how much data it will hold.
By specifying the length at the beginning of the transmit phase, each DATA
packet length can be set before we start loading data from userspace (where
several sendmsg() calls may contribute to a particular packet).
An error will be returned if too little or too much data is presented in
the Tx phase.

The command
# arp -s 62.2.0.1 a:b:c:d:e:f dev eth2
adds an entry like the following (listed by "arp -an")
? (62.2.0.1) at 0a:0b:0c:0d:0e:0f [ether] PERM on eth2
but the symmetric deletion command
# arp -i eth2 -d 62.2.0.1
does not remove the PERM entry from the table, and instead leaves behind
? (62.2.0.1) at <incomplete> on eth2
The reason is that there is a refcnt of 1 for the arp_tbl itself
(neigh_alloc starts off the entry with a refcnt of 1), thus
the neigh_release() call from arp_invalidate() will (at best) just
decrement the ref to 1, but will never actually free it from the
table.
To fix this, we need to do something like neigh_forced_gc: if
the refcnt is 1 (i.e., on the table's ref), remove the entry from
the table and free it. This patch refactors and shares common code
between neigh_forced_gc and the newly added neigh_remove_one.
A similar issue exists for IPv6 Neighbor Cache entries, and is fixed
in a similar manner by this patch.

Whenever a user changes bonding options, a NETDEV_CHANGEINFODATA
notificatin is generated which results in a rtnelink message to
be sent. While runnig 'ip monitor', we can actually see 2 messages,
one a result of the event, and the other a result of state change
that is generated bo netdev_state_change(). However, this is not
always the case. If bonding changes were done via sysfs or ifenslave
(old ioctl interface), then only 1 message is seen.
This patch removes duplicate messages in the case of using netlink
to configure bonding. It introduceds a separte function that
triggers a netdev event and uses that function in the syfs and ioctl
cases.
This was discovered while auditing all the different envents and
continues the effort of cleaning up duplicated netlink messages.

Cong Wang attempted to add back rt->fi in commit
82486aa6f1b9 ("ipv4: restore rt->fi for reference counting")
but this proved to add some issues that were complex to solve.
Instead, I suggested to add a refcount to the metrics themselves,
being a standalone object (in particular, no reference to other objects)
I tried to make this patch as small as possible to ease its backport,
instead of being super clean. Note that we believe that only ipv4 dst
need to take care of the metric refcount. But if this is wrong,
this patch adds the basic infrastructure to extend this to other
families.

A later patch wants access to the fib result on an output route lookup
with the rcu lock held. Refactor __ip_route_output_key_hash, pushing
the logic between rcu_read_lock ... rcu_read_unlock into a new helper
with the fib_result as an input arg.
To keep the name length under control remove the leading underscores
from the name and add _rcu to the name of the new helper indicating it
is called with the rcu read lock held.
