Pull networking updates from Paolo Abeni:
"Core:
- Implement the Device Memory TCP transmit path, allowing zero-copy
data transmission on top of TCP from e.g. GPU memory to the wire.
- Move all the IPv6 routing tables management outside the RTNL scope,
under its own lock and RCU. The route control path is now 3x times
faster.
- Convert queue related netlink ops to instance lock, reducing again
the scope of the RTNL lock. This improves the control plane
scalability.
- Refactor the software crc32c implementation, removing unneeded
abstraction layers and improving significantly the related
micro-benchmarks.
- Optimize the GRO engine for UDP-tunneled traffic, for a 10%
performance improvement in related stream tests.
- Cover more per-CPU storage with local nested BH locking; this is a
prep work to remove the current per-CPU lock in local_bh_disable()
on PREMPT_RT.
- Introduce and use nlmsg_payload helper, combining buffer bounds
verification with accessing payload carried by netlink messages.
Netfilter:
- Rewrite the procfs conntrack table implementation, improving
considerably the dump performance. A lot of user-space tools still
use this interface.
- Implement support for wildcard netdevice in netdev basechain and
flowtables.
- Integrate conntrack information into nft trace infrastructure.
- Export set count and backend name to userspace, for better
introspection.
BPF:
- BPF qdisc support: BPF-qdisc can be implemented with BPF struct_ops
programs and can be controlled in similar way to traditional qdiscs
using the "tc qdisc" command.
- Refactor the UDP socket iterator, addressing long standing issues
WRT duplicate hits or missed sockets.
Protocols:
- Improve TCP receive buffer auto-tuning and increase the default
upper bound for the receive buffer; overall this improves the
single flow maximum thoughput on 200Gbs link by over 60%.
- Add AFS GSSAPI security class to AF_RXRPC; it provides transport
security for connections to the AFS fileserver and VL server.
- Improve TCP multipath routing, so that the sources address always
matches the nexthop device.
- Introduce SO_PASSRIGHTS for AF_UNIX, to allow disabling SCM_RIGHTS,
and thus preventing DoS caused by passing around problematic FDs.
- Retire DCCP socket. DCCP only receives updates for bugs, and major
distros disable it by default. Its removal allows for better
organisation of TCP fields to reduce the number of cache lines hit
in the fast path.
- Extend TCP drop-reason support to cover PAWS checks.
Driver API:
- Reorganize PTP ioctl flag support to require an explicit opt-in for
the drivers, avoiding the problem of drivers not rejecting new
unsupported flags.
- Converted several device drivers to timestamping APIs.
- Introduce per-PHY ethtool dump helpers, improving the support for
dump operations targeting PHYs.
Tests and tooling:
- Add support for classic netlink in user space C codegen, so that
ynl-c can now read, create and modify links, routes addresses and
qdisc layer configuration.
- Add ynl sub-types for binary attributes, allowing ynl-c to output
known struct instead of raw binary data, clarifying the classic
netlink output.
- Extend MPTCP selftests to improve the code-coverage.
- Add tests for XDP tail adjustment in AF_XDP.
New hardware / drivers:
- OpenVPN virtual driver: offload OpenVPN data channels processing to
the kernel-space, increasing the data transfer throughput WRT the
user-space implementation.
- Renesas glue driver for the gigabit ethernet RZ/V2H(P) SoC.

This patch addresses below issues,
1. Active traffic on the leaf node must be stopped before its send queue
is reassigned to the parent. This patch resolves the issue by marking
the node as 'Inner'.
2. During a system reboot, the interface receives TC_HTB_LEAF_DEL
and TC_HTB_LEAF_DEL_LAST callbacks to delete its HTB queues.
In the case of TC_HTB_LEAF_DEL_LAST, although the same send queue
is reassigned to the parent, the current logic still attempts to update
the real number of queues, leadning to below warnings
New queues can't be registered after device unregistration.

When enabling 1-step timestamping for ptp frames that are over udpv4 or
udpv6 then the inserted timestamp is added at the wrong offset in the
frame, meaning that will modify the frame at the wrong place, so the
frame will be malformed.
To fix this, the HW needs to know which kind of frame it is to know
where to insert the timestamp. For that there is a field in the IFH that
says the PDU_TYPE, which can be NONE which is the default value,
IPV4 or IPV6. Therefore make sure to set the PDU_TYPE so the HW knows
where to insert the timestamp.
Like I mention before the issue is not seen with L2 frames because by
default the PDU_TYPE has a value of 0, which represents the L2 frames.

The driver needs to handle GPIO interrupts to identify SFP module and
configure PHY by sending mailbox messages to firmware.
Since the SFP module needs to wait for ready to get information when it
is inserted, workqueue is added to handle delayed tasks. And each SW-FW
interaction takes time to wait, so they are processed in the workqueue
instead of IRQ handler function.

As it's name suggests, parse_eeprom() parses EEPROM data.
This is done by reading data, 16 bits at a time as follows:
for (i = 0; i < 128; i++)
((__le16 *) sromdata)[i] = cpu_to_le16(read_eeprom(np, i));
sromdata is at the same memory location as psrom.
And the type of psrom is a pointer to struct t_SROM.
As can be seen in the loop above, data is stored in sromdata, and thus
psrom, as 16-bit little-endian values. However, the integer fields of
t_SROM are host byte order.
In the case of the led_mode field this results in a but which has been
addressed by commit e7e5ae71831c ("net: dlink: Correct endianness
handling of led_mode").
In the case of the remaining fields, which are updated by this patch,
I do not believe this does not result in any bugs. But it does seem
best to correctly annotate the endianness of integers.

If the user unbinds both PF0 and SDP-VF0 interfaces and then binds them in
reverse order
PF NIXLF

SDP-VF0 0

In this scenario, the PF0 unicast entry is getting corrupted because
the MCAM entry contains stale data (SDP-VF0 ucast data)

This patch convert mlx5 to use the new netdev instance lock in addition
to the pre-existing state_lock (and the RTNL).
mlx5e_priv.state_lock was already used throughout mlx5 to protect
against concurrent state modifications on the same netdev, usually in
addition to the RTNL. The new netdev instance lock will eventually
replace it, but for now, it is acquired in addition to the existing
locks in the order RTNL -> instance lock -> state_lock.
All three netdev types handled by mlx5 are converted to the new style of
locking, because they share a lot of code related to initializing
channels and dealing with NAPI, so it's better to convert all three
rather than introduce different assumptions deep in the call stack
depending on the type of device.
Because of the nature of the call graphs in mlx5, it wasn't possible to
incrementally convert parts of the driver to use the new lock, since
either all call paths into NAPI have to possess the new lock if the
*_locked variants are used, or none of them can have the lock.
One area which required extra care is the interaction between closing
channels and devlink health reporter tasks.
Previously, the recovery tasks were unconditionally acquiring the
RTNL, which could lead to deadlocks in these scenarios:
T1: mlx5e_close (== .ndo_stop(), has RTNL) -> mlx5e_close_locked
-> mlx5e_close_channels -> mlx5e_ptp_close
-> mlx5e_ptp_close_queues -> mlx5e_ptp_close_txqsqs
-> mlx5e_ptp_close_txqsq
-> cancel_work_sync(&ptpsq->report_unhealthy_work) waits for
T2: mlx5e_ptpsq_unhealthy_work -> mlx5e_reporter_tx_ptpsq_unhealthy
-> mlx5e_health_report -> devlink_health_report
-> devlink_health_reporter_recover
-> mlx5e_tx_reporter_ptpsq_unhealthy_recover which does:
rtnl_lock(); => Deadlock.
Another similar instance of this is:
T1: mlx5e_close (== .ndo_stop(), has RTNL) -> mlx5e_close_locked
-> mlx5e_close_channels -> mlx5e_ptp_close
-> mlx5e_ptp_close_queues -> mlx5e_ptp_close_txqsqs
-> mlx5e_ptp_close_txqsq
-> cancel_work_sync(&sq->recover_work) waits for
T2: mlx5e_tx_err_cqe_work -> mlx5e_reporter_tx_err_cqe
-> mlx5e_health_report -> devlink_health_report
-> devlink_health_reporter_recover
-> mlx5e_tx_reporter_err_cqe_recover which does:
rtnl_lock(); => Another deadlock.
Fix that by using the same pattern previously done in
mlx5e_tx_timeout_work, where the RTNL was repeatedly tried to be
acquired until either:
a) it is successfully acquired or
b) there's no need for the work to be done any more (channel is being
closed).
Now, for all three recovery tasks, the instance lock is repeatedly tried
to be acquired until successful or the channel/SQ is closed.
As a side-effect, drop the !test_bit(MLX5E_STATE_OPENED, &priv->state)
check from mlx5e_tx_timeout_work, it's weaker than
!test_bit(MLX5E_STATE_CHANNELS_ACTIVE, &priv->state) and unnecessary.
Future patches will introduce new call paths (from netdev queue
management ops) which can close channels (and call cancel_work_sync on
the recovery tasks) without the RTNL lock and only with the netdev
instance lock.

There's no explanation in the original commit of why that was done, but
presumably flashing takes a long time and holding RTNL for so long
blocks other interactions with the netdev layer.
However, the stack is moving towards netdev instance locking and
dropping and reacquiring RTNL in the context of flashing introduces
locking ordering issues: RTNL must be acquired before the netdev
instance lock and released after it.
This patch therefore takes the simpler approach by no longer dropping
and reacquiring the RTNL, as soon RTNL for ethtool will be removed,
leaving only the instance lock to protect against races.

When xdp is attached or detached, dev->ndo_bpf() is called by
do_setlink(), and it acquires netdev_lock() if needed.
Unlike other drivers, the bnxt driver is protected by netdev_lock while
xdp is attached/detached because it sets dev->request_ops_lock to true.
So, the bnxt_xdp(), that is callback of ->ndo_bpf should not acquire
netdev_lock().
But the xdp_features_{set | clear}_redirect_target() was changed to
acquire netdev_lock() internally.
It causes a deadlock.
To fix this problem, bnxt driver should use
xdp_features_{set | clear}_redirect_target_locked() instead.

Having adjacent accelerated modify header actions (so-called
pattern-argument actions) may result in inconsistent outcome.
These inconsistencies can take the form of writes to the same
field or a read coupled with a write to the same field. The
solution is to detect such dependencies and insert nops between
the offending actions.
The existing implementation had a few issues, which pretty much
required a complete rewrite of the code that handles these
dependencies.
In the new implementation we're doing the following:
* Checking any two adjacent actions for conflicts (not just
odd-even pairs).
* Marking 'set' and 'add' action fields as destination, rather
than source, for the purposes of checking for conflicts.
* Checking all types of actions ('add', 'set', 'copy') for
dependencies.
* Managing offsets of the args in the buffer - copy the action
args to the right place in the buffer.
* Checking that after inserting nops we're still within the number
of supported actions - return an error otherwise.
