Now that commit 028fb19c ("netlink: provide an ability to set

an existing extack message provided by the driver, it makes sense to use
it also for LAG and HSR offloading, not just for bridge offloading.

Also consistently put the message string on a separate line, to reduce

net: Allow offloading of UDP NEW connections via act_ct

Currently only bidirectional established connections can be offloaded
via act_ct. Such approach allows to hardcode a lot of assumptions into
act_ct, flow_table and flow_offload intermediate layer codes. In order
to enabled offloading of unidirectional UDP NEW connections start with
incrementally changing the following assumptions:

- Drivers assume that only established connections are offloaded and
  don't support updating existing connections. Extract ctinfo from meta
  action cookie and refuse offloading of new connections in the drivers.

- Fix flow_table offload fixup algorithm to calculate flow timeout
  according to current connection state instead of hardcoded
  "established" value.

- Add new flow_table flow flag that designates bidirectional connections
  instead of assuming it and hardcoding hardware offload of every flow
  in both directions.

- Add new flow_table flow flag that designates connections that are
  offloaded to hardware as "established" instead of assuming it. This
  allows some optimizations in act_ct and prevents spamming the
  flow_table workqueue with redundant tasks.

With all the necessary infrastructure in place modify act_ct to offload
UDP NEW as unidirectional connection. Pass reply direction traffic to CT
and promote connection to bidirectional when UDP connection state
changes to "assured". Rely on refresh mechanism to propagate connection
state change to supporting drivers.

Note that early drop algorithm that is designed to free up some space in
connection tracking table when it becomes full (by randomly deleting up
to 5% of non-established connections) currently ignores connections
marked as "offloaded". Now, with UDP NEW connections becoming
"offloaded" it could allow malicious user to perform DoS attack by
filling the table with non-droppable UDP NEW connections by sending just
one packet in single direction. To prevent such scenario change early
drop algorithm to also consider "offloaded" connections for deletion.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>

Both synchronous early drop algorithm and asynchronous gc worker completely
ignore connections with IPS_OFFLOAD_BIT status bit set. With new
functionality that enabled UDP NEW connection offload in action CT
malicious user can flood the conntrack table with offloaded UDP connections
by just sending a single packet per 5tuple because such connections can no
longer be deleted by early drop algorithm.

To mitigate the issue allow both early drop and gc to consider offloaded
UDP connections for deletion.

Modify the offload algorithm of UDP connections to the following:

- Offload NEW connection as unidirectional.

- When connection state changes to ESTABLISHED also update the hardware
flow. However, in order to prevent act_ct from spamming offload add wq for
every packet coming in reply direction in this state verify whether
connection has already been updated to ESTABLISHED in the drivers. If that
it the case, then skip flow_table and let conntrack handle such packets
which will also allow conntrack to potentially promote the connection to
ASSURED.

- When connection state changes to ASSURED set the flow_table flow
NF_FLOW_HW_BIDIRECTIONAL flag which will cause refresh mechanism to offload
the reply direction.

All other protocols have their offload algorithm preserved and are always
offloaded as bidirectional.

Note that this change tries to minimize the load on flow_table add
workqueue. First, it tracks the last ctinfo that was offloaded by using new
flow 'NF_FLOW_HW_ESTABLISHED' flag and doesn't schedule the refresh for
reply direction packets when the offloads have already been updated with
current ctinfo. Second, when 'add' task executes on workqueue it always
update the offload with current flow state (by checking 'bidirectional'
flow flag and obtaining actual ctinfo/cookie through meta action instead of
caching any of these from the moment of scheduling the 'add' work)
preventing the need from scheduling more updates if state changed
concurrently while the 'add' work was pending on workqueue.

net: renesas: rswitch: Modify initialization for SERDES and PHY

- My platform has the 88x2110.
- The MACTYPE setting of strap pin on the platform is SXGMII.
- However, we realized that the SoC cannot communicate the PHY with SXGMII
  because of mismatching hardware specification.
- We have a lot of boards which mismatch the MACTYPE setting.

So, I would like to change the MACTYPE as SGMII by software for the platform.

The patch [1/5] sets phydev->host_interfaces by phylink for Marvell PHY
driver (marvell10g) to initialize the MACTYPE.

- The patch [1/5] siplifies the rswitch driver.
- The patch [2/5] converts to phy_device from phylink.
- The patch [3/5] sets phydev->host_interfaces from this driver without
  any new functions of phylib.
- The patch [4/5] adds phy_power_on() calling to initialize the Ethernet
  SERDES PHY driver (r8a779f0-eth-serdes) for each channel.
- The patch [5/5] adds "max-speed" handling.

Changes from v4:
https://lore.kernel.org/all/20230127142621.1761278-1-yoshihiro.shimoda.uh@renesas.com/

Some Ethernet PHYs (like marvell10g) will decide the host interface
mode by the media-side speed. So, the rswitch driver needs to
initialize one of the Ethernet SERDES (r8a779f0-eth-serdes) ports
after linked the Ethernet PHY up. The r8a779f0-eth-serdes driver has
.init() for initializing all ports and .power_on() for initializing
each port. So, add phy_power_{on,off} calling for it.

There are cases when the SGMII_PHYA_PWD register contains 0x9 which
prevents SGMII from working. The SGMII still shows link but no traffic
can flow. Writing 0x0 to the PHYA_PWD register fix the issue. 0x0 was
taken from a good working state of the SGMII interface.

====================
can 2023-02-02

The first patch is by Ziyang Xuan and removes a errant WARN_ON_ONCE()
in the CAN J1939 protocol.

The next 3 patches are by Oliver Hartkopp. The first 2 target the CAN
ISO-TP protocol and fix the state machine with respect to signals and
a regression found by the syzbot.

The last patch is by me an missing assignment during the ethtool ring
configuration callback.
