We introduce a new macro TIPC_ANY_SCOPE to make the handling of the
lookup scope value more comprehensible during multicast reception.
The (unchanged) rules go as follows:
1) Multicast messages sent from own node are delivered to all matching
sockets on the own node, irrespective of their binding scope.
2) Multicast messages sent from other nodes arrive here because they
have found TIPC_CLUSTER_SCOPE bindings emanating from this node.
Those messages should be delivered to exactly those sockets, but not
to local sockets bound with TIPC_NODE_SCOPE, since the latter
obviously were not meant to be visible for those senders.
3) Group multicast/broadcast messages are delivered to the sockets with
a binding scope matching exactly the lookup scope indicated in the
message header, and nobody else.

We eliminate the redundant fields conn_type and conn_instance in
struct tipc_sock. On the connecting side, this information is already
present in the unused (after the connection is established) part of
the pre-allocated header, and on the accepting side, we put it there
when the new socket is created.

smc_lgr_cleanup() calls smcd_unregister_all_dmbs() as part of the link
group termination process. This is a leftover from the times when
smc_lgr_cleanup() scheduled a worker to actually free the link group.
Nowadays smc_lgr_cleanup() directly calls smc_lgr_free() without any
delay so an earlier dmb unregistration is no longer needed.
So remove smcd_unregister_all_dmbs() and the call to it.

Refactor DEVLINK_CMD_RATE_{GET|SET} command handlers to support setting
a node as a parent for another rate object (leaf or node) by means of
new attribute DEVLINK_ATTR_RATE_PARENT_NODE_NAME. Extend devlink ops
with new callbacks rate_{leaf|node}_parent_set() to set node as a parent
for rate object to allow supporting drivers to implement rate grouping
through devlink. Driver implementations are allowed to support leafs
or node children only. Invoking callback with NULL as parent should be
threated by the driver as unset parent action.
Extend rate object struct with reference counter to disallow deleting a
node with any child pointing to it. User should unset parent for the
child explicitly.
Example:
$ devlink port function rate add netdevsim/netdevsim10/group1
$ devlink port function rate add netdevsim/netdevsim10/group2
$ devlink port function rate set netdevsim/netdevsim10/group1 parent group2
$ devlink port function rate show netdevsim/netdevsim10/group1
netdevsim/netdevsim10/group1: type node parent group2
$ devlink port function rate set netdevsim/netdevsim10/group1 noparent

Implement support for DEVLINK_CMD_RATE_{NEW|DEL} commands that are used
to create and delete devlink rate nodes. Add new attribute
DEVLINK_ATTR_RATE_NODE_NAME that specify node name string. The node name
is an alphanumeric identifier. No valid node name can be a devlink port
index, eg. decimal number. Extend devlink ops with new callbacks
rate_node_{new|del}() and rate_node_tx_{share|max}_set() to allow
supporting drivers to implement ports rate grouping and setting tx rate
of rate nodes through devlink.
Expose devlink_rate_nodes_destroy() function to allow vendor driver do
proper cleanup of internally allocated resources for the nodes if the
driver goes down or due to any other reasons which requires nodes to be
destroyed.
Disallow moving device from switchdev to legacy mode if any node exists
on that device. User must explicitly delete nodes before switching mode.
Example:
$ devlink port function rate add netdevsim/netdevsim10/group1
$ devlink port function rate set netdevsim/netdevsim10/group1 \
tx_share 10mbit tx_max 100mbit
Add + set command can be combined:
$ devlink port function rate add netdevsim/netdevsim10/group1 \
tx_share 10mbit tx_max 100mbit
$ devlink port function rate show netdevsim/netdevsim10/group1
netdevsim/netdevsim10/group1: type node tx_share 10mbit tx_max 100mbit
$ devlink port function rate del netdevsim/netdevsim10/group1

Implement support for DEVLINK_CMD_RATE_SET command with new attributes
DEVLINK_ATTR_RATE_TX_{SHARE|MAX} that are used to set devlink rate
shared/max tx rate values. Extend devlink ops with new callbacks
rate_leaf_tx_{share|max}_set() to allow supporting drivers to implement
rate control through devlink.
New attributes are optional. Driver implementations are allowed to
support either or both of them.
Shared rate example:
$ devlink port function rate set netdevsim/netdevsim10/0 tx_share 10mbit
$ devlink port function rate show netdevsim/netdevsim10/0
netdevsim/netdevsim10/0: type leaf tx_share 10mbit

Currently vlan modification action checks existence of vlan priority by
comparing it to 0. Therefore it is impossible to modify existing vlan
tag to have priority 0.
For example, the following tc command will change the vlan id but will
not affect vlan priority:
tc filter add dev eth1 ingress matchall action vlan modify id 300 \
priority 0 pipe mirred egress redirect dev eth2
The incoming packet on eth1:
ethertype 802.1Q (0x8100), vlan 200, p 4, ethertype IPv4
will be changed to:
ethertype 802.1Q (0x8100), vlan 300, p 4, ethertype IPv4
although the user has intended to have p == 0.
The fix is to add tcfv_push_prio_exists flag to struct tcf_vlan_params
and rely on it when deciding to set the priority.

This is a complement to commit aa6dd211e4b1 ("inet: use bigger hash
table for IP ID generation"), but focusing on some specific aspects
of IPv6.
Contary to IPv4, IPv6 only uses packet IDs with fragments, and with a
minimum MTU of 1280, it's much less easy to force a remote peer to
produce many fragments to explore its ID sequence. In addition packet
IDs are 32-bit in IPv6, which further complicates their analysis. On
the other hand, it is often easier to choose among plenty of possible
source addresses and partially work around the bigger hash table the
commit above permits, which leaves IPv6 partially exposed to some
possibilities of remote analysis at the risk of weakening some
protocols like DNS if some IDs can be predicted with a good enough
probability.
Given the wide range of permitted IDs, the risk of collision is extremely
low so there's no need to rely on the positive increment algorithm that
is shared with the IPv4 code via ip_idents_reserve(). We have a fast
PRNG, so let's simply call prandom_u32() and be done with it.
Performance measurements at 10 Gbps couldn't show any difference with
the previous code, even when using a single core, because due to the
large fragments, we're limited to only ~930 kpps at 10 Gbps and the cost
of the random generation is completely offset by other operations and by
the network transfer time. In addition, this change removes the need to
update a shared entry in the idents table so it may even end up being
slightly faster on large scale systems where this matters.
The risk of at least one collision here is about 1/80 million among
10 IDs, 1/850k among 100 IDs, and still only 1/8.5k among 1000 IDs,
which remains very low compared to IPv4 where all IDs are reused
every 4 to 80ms on a 10 Gbps flow depending on packet sizes.

To avoid confusions, it seems better to parse this sysctl parameter as a
boolean. We use it as a boolean, no need to parse an integer and bring
confusions if we see a value different from 0 and 1, especially with
this parameter name: enabled.
It seems fine to do this modification because the default value is 1
(enabled). Then the only other interesting value to set is 0 (disabled).
All other values would not have changed the default behaviour.

Since the introduction of the sysctl support in MPTCP with
commit 784325e9f037 ("mptcp: new sysctl to control the activation per NS"),
we don't check CONFIG_SYSCTL.
Until now, that was not an issue: the register and unregister functions
were replaced by NO-OP one if SYSCTL was not enabled in the config. The
only thing we could have avoid is not to reserve memory for the table
but that's for the moment only a small table per net-ns.
But the following commit is going to use SYSCTL_ZERO and SYSCTL_ONE
which are not be defined if SYSCTL is not enabled in the config. This
causes 'undefined reference' errors from the linker.

After commit 2c5ebd001d4f ("mptcp: refactor token container"),
pr_debug() is called before mptcp_crypto_key_gen_sha() in
mptcp_token_new_connect(), so the output local_key, token and
idsn are 0, like:
MPTCP: ssk=00000000f6b3c4a2, local_key=0, token=0, idsn=0
Move pr_debug() after mptcp_crypto_key_gen_sha().
Fixes: 2c5ebd001d4f ("mptcp: refactor token container")
