Remove one pair of add/adc instructions and their dependency
against carry flag.
We can leverage third argument to csum_partial():
X = csum_block_sub(X, csum_partial(start, len, 0), 0);
-->
X = csum_block_add(X, ~csum_partial(start, len, 0), 0);
-->
X = ~csum_partial(start, len, ~X);

Currently, the probe timer is reused as the raise timer when PLPMTUD is in
the Search Complete state. raise_count was introduced to count how many
times the probe timer has timed out. When raise_count reaches to 30, the
raise timer handler will be triggered.
During the whole processing above, the timer keeps timing out every probe_
interval. It is a waste for the Search Complete state, as the raise timer
only needs to time out after 30 * probe_interval.
Since the raise timer and probe timer are never used at the same time, it
is no need to keep probe timer 'alive' in the Search Complete state. This
patch to introduce sctp_transport_reset_raise_timer() to start the timer
as the raise timer when entering the Search Complete state. When entering
the other states, sctp_transport_reset_probe_timer() will still be called
to reset the timer to the probe timer.
raise_count can be removed from sctp_transport as no need to count probe
timer timeout for raise timer timeout. last_rtx_chunks can be removed as
sctp_transport_reset_probe_timer() can be called in the place where asoc
rtx_data_chunks is changed.

When a skb comes to tipc_aead_encrypt(), it's always linear. The
unlikely check 'skb_cloned(skb) && tailen <= skb_tailroom(skb)'
can completely be taken care of in skb_cow_data() by the code
in branch "if (!skb_has_frag_list())".
Also, remove the 'TODO:' annotation, as the pages in skbs are not

====================
net: ipa: GSI channel flow control
Starting with IPA v4.2, endpoint DELAY mode (which prevents data
transfer on TX endpoints) does not work properly. To address this,
changes were made to allow underlying GSI channels to be put into
a "flow controlled" state, which achieves a similar objective.
The first patch in this series implements the flow controlled
channel state and the commands used to control it. It arranges
to use the new mechanism--instead of DELAY mode--for IPA v4.2+.
In IPA v4.11, the notion of GSI channel flow control was enhanced,
and implemented in a slightly different way. For the most part this
doesn't affect the way the IPA driver uses flow control, but the
second patch adds support for the newer mechanism.

IPA v4.2 introduced GSI channel flow control, used instead of IPA
endpoint DELAY mode to prevent a TX channel from injecting packets
into the IPA core. It used a new FLOW_CONTROLLED channel state
which could be entered using GSI generic commands.
IPA v4.11 extended the channel flow control model. Rather than
having a distinct FLOW_CONTROLLED channel state, each channel has a
"flow control" property that can be enabled or not--independent of
the channel state. The AP (or modem) can modify this property using
the same GSI generic commands as before.
The AP only uses channel flow control on modem TX channels, and only
when recovering from a modem crash. The AP has no way to discover
the state of a modem channel, so the fact that (starting with IPA
v4.11) flow control no longer uses a distinct channel state is
invisible to the AP. So enhanced flow control generally does not
change the way AP uses flow control.
There are a few small differences, however:
- There is a notion of "primary" or "secondary" flow control, and
when enabling or disabling flow control that must be specified
in a new field in the GSI generic command register. For now, we
always specify 0 (meaning "primary").
- When disabling flow control, it's possible a request will need
to be retried. We retry up to 5 times in this case.
- Another new generic command allows the current flow control
state to be queried. We do not use this.
Other than the need for retries, the code essentially works the same
way as before.

One quirk for certain versions of IPA is that endpoint DELAY mode
does not work properly. IPA DELAY mode prevents any packets from
being delivered to the IPA core for processing on a TX endpoint.
The AP uses DELAY mode when the modem crashes, to prevent modem TX
endpoints from generating traffic during crash recovery. Without
this, there is a chance the hardware will stall during recovery from
a modem crash.
To achieve a similar effect, a GSI FLOW_CONTROLLED channel state
was created. A STARTED TX channel can be placed in FLOW_CONTROLLED
state, which prevents the transfer of any more packets. A channel
in FLOW_CONTROLLED state can be either returned to STARTED state, or
can be transitioned to STOPPED state.
Because this operates on GSI channels, two generic commands were
added to allow the AP to control this state for modem channels
(similar to the ALLOCATE and HALT channel commands).
Previously the code assumed this quirk only applied to IPA v4.2.
In fact, channel flow control (rather than endpoint DELAY mode)
should be used for all versions *starting* with IPA v4.2.

The current serial driver requires a maximum MTU of 68, and it doesn't
make sense to set a MTU below the MCTP-required baseline (of 68) either.
This change sets the min_mtu & max_mtu of the mctp netdev, essentially
disallowing changes. By using these instead of a ndo_change_mtu op, we
get the netlink extacks reported too.

The dummy net_device is a large field in the GSI structure, but it
is not at all interesting from the perspective of debugging. Move
it to the end of the GSI structure so the other fields are easier to
find in memory.
The channel and event ring arrays are also very large, so move them
near the end of the structure as well.
Swap the position of the result and completion fields to improve
structure packing.

A mutex ensures we never submit more than one GSI command of any
kind at once. This means the per-channel and per-event ring
completion structures provide no benefit. Instead, just use the
single (existing) GSI completion to signal the completion of GSI
commands of all types.
This makes gsi_evt_ring_init() a trivial function with no inverse,
so open-code it in its sole caller and get rid of the function.

In ipa_endpoint_skb_copy(), a new socket buffer structure is
allocated so that some data can be copied into it. However, after
doing this, if the endpoint has a null netdev pointer, we just drop
free the socket buffer.
Instead, check endpoint->netdev pointer first, and just return early
if it's null. Also return early if the SKB allocation fails, to
avoid the deeper indentation in the normal path.

During setup, ipa_endpoint_program() programs each endpoint with
various configuration parameters. One of those registers defines
whether to drop packets when a head-of-line blocking condition is

The head-of-line block (HOLB) drop timer is only meaningful when
dropping packets due to blocking is enabled. Given that, redefine
the interface so the timer is specified when enabling HOLB drop, and
use a different function when disabling.
To enable and disable HOLB drop, these functions will now be used:
ipa_endpoint_init_hol_block_enable(endpoint, milliseconds)
ipa_endpoint_init_hol_block_disable(endpoint)
The existing ipa_endpoint_init_hol_block_enable() becomes a helper
function, renamed ipa_endpoint_init_hol_block_en(), and used with
ipa_endpoint_init_hol_block_timer() to enable HOLB block on an
endpoint.

Not all filter table entries are used. Only certain endpoints
support filtering, and the table begins with a bitmap indicating
which endpoints use the "slots" that follow for filter rules.
Currently, unused filter table entries are not initialized.
Instead, zero-fill the entire unused portion of the filter table
memory regions, to make it more obvious that memory is unused (and
not subsequently modified).
This is not strictly necessary, but the result is reassuring when
looking at filter table memory.

The VSC9959 switch embedded within NXP LS1028A (and that version of
Ocelot switches only) supports cut-through forwarding - meaning it can
start the process of looking up the destination ports for a packet, and
forward towards those ports, before the entire packet has been received
(as opposed to the store-and-forward mode).
The up side is having lower forwarding latency for large packets. The
down side is that frames with FCS errors are forwarded instead of being
dropped. However, erroneous frames do not result in incorrect updates of
the FDB or incorrect policer updates, since these processes are deferred
inside the switch to the end of frame. Since the switch starts the
cut-through forwarding process after all packet headers (including IP,
if any) have been processed, packets with large headers and small
payload do not see the benefit of lower forwarding latency.
There are two cases that need special attention.
The first is when a packet is multicast (or flooded) to multiple
destinations, one of which doesn't have cut-through forwarding enabled.
The switch deals with this automatically by disabling cut-through
forwarding for the frame towards all destination ports.
The second is when a packet is forwarded from a port of lower link speed
towards a port of higher link speed. This is not handled by the hardware
and needs software intervention.
Since we practically need to update the cut-through forwarding domain
from paths that aren't serialized by the rtnl_mutex (phylink
mac_link_down/mac_link_up ops), this means we need to serialize physical
link events with user space updates of bonding/bridging domains.
Enabling cut-through forwarding is done per {egress port, traffic class}.
I don't see any reason why this would be a configurable option as long
as it works without issues, and there doesn't appear to be any user
space configuration tool to toggle this on/off, so this patch enables
cut-through forwarding on all eligible ports and traffic classes.

This is to match ipv4 behaviour, see __ip_sock_set_tos()
implementation.
Technically for ipv6 this might not be required because normally we
do not allow tclass to influence routing, yet the cli tooling does
support it:
lpk11:~# ip -6 rule add pref 5 tos 45 lookup 5
lpk11:~# ip -6 rule
5: from all tos 0x45 lookup 5
and in general dscp/tclass based routing does make sense.
We already have cases where dscp can affect vlan priority and/or
transmit queue (especially on wifi).
So let's just make things match. Easier to reason about and no harm.

A CAP_NET_RAW capable process can already spoof (on transmit) anything
it desires via raw packet sockets... There is no good reason to not
allow it to also be able to play routing tricks on packets from its
own normal sockets.
There is a desire to be able to use SO_MARK for routing table selection
(via ip rule fwmark) from within a user process without having to run
it as root. Granting it CAP_NET_RAW is much less dangerous than
CAP_NET_ADMIN (CAP_NET_RAW doesn't permit persistent state change,
while CAP_NET_ADMIN does - by for example allowing the reconfiguration
of the routing tables and/or bringing up/down devices).
Let's keep CAP_NET_ADMIN for persistent state changes,
while using CAP_NET_RAW for non-configuration related stuff.

CAP_NET_ADMIN is and should continue to be about configuring the
system as a whole, not about configuring per-socket or per-packet
parameters.
Sending and receiving raw packets is what CAP_NET_RAW is all about.
It can already send packets with any VLAN tag, and any IPv4 TOS
mark, and any IPv6 TCLASS mark, simply by virtue of building
such a raw packet. Not to mention using any protocol and source/
/destination ip address/port tuple.
These are the fields that networking gear uses to prioritize packets.
Hence, a CAP_NET_RAW process is already capable of affecting traffic
prioritization after it hits the wire. This change makes it capable
of affecting traffic prioritization even in the host at the nic and
before that in the queueing disciplines (provided skb->priority is
actually being used for prioritization, and not the TOS/TCLASS field)
Hence it makes sense to allow a CAP_NET_RAW process to set the
priority of sockets and thus packets it sends.

Currently, there is no way to get drop packet number of multicast and
broadcast in IGU hardware module, it is not convenient to find problem
when multicast packet or broadcast packet is dropped in IGU, so this
patch adds statistics for them in debugfs.

Printing the whole MAC addresse may bring security risks. Therefore,
the MAC address is partially encrypted to improve security.

When the mbx or reset message arrives, the driver is informed
through an interrupt. This task can be processed only after
the workqueue is scheduled. In some cases, this workqueue
scheduling takes a long time. As a result, the mbx or reset
service task cannot be processed in time. So add some warning
message to improve debugging efficiency for this case.

This patch inlines dccp_listen_start() and removes a stale comment in
inet_dccp_listen() so that it looks like inet_listen().

The commit 1295e2cf3065 ("inet: minor optimization for backlog setting in
listen(2)") added change so that sk_max_ack_backlog is initialised earlier
in inet_dccp_listen() and inet_listen(). Since then, we no longer use
backlog in inet_csk_listen_start(), so let's remove it.
