Merge tag 'net-next-6.16' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

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.

- Broadcom asp-v3.0 ethernet driver.

====================
igc: Add support for Frame Preemption

Faizal Rahim says:

Introduce support for the FPE feature in the IGC driver.

The patches aligns with the upstream FPE API:
https://patchwork.kernel.org/project/netdevbpf/cover/20230220122343.1156614-1-vladimir.oltean@nxp.com/
https://patchwork.kernel.org/project/netdevbpf/cover/20230119122705.73054-1-vladimir.oltean@nxp.com/

It builds upon earlier work:
https://patchwork.kernel.org/project/netdevbpf/cover/20220520011538.1098888-1-vinicius.gomes@intel.com/

The patch series adds the following functionalities to the IGC driver:
a) Configure FPE using `ethtool --set-mm`.
b) Display FPE settings via `ethtool --show-mm`.
c) View FPE statistics using `ethtool --include-statistics --show-mm'.
e) Block setting preemptible tc in taprio since it is not supported yet.
Existing code already blocks it in mqprio.

Tested:
Enabled CONFIG_PROVE_LOCKING, CONFIG_DEBUG_ATOMIC_SLEEP, CONFIG_DMA_API_DEBUG, and CONFIG_KASAN
1) selftests
2) netdev down/up cycles
3) suspend/resume cycles
4) fpe verification

No bugs or unusual dmesg logs were observed.
Ran 1), 2) and 3) with and without the patch series, compared dmesg and selftest logs - no differences found.

igc: add support for frame preemption verification

This patch implements the "ethtool --set-mm" callback to trigger the
frame preemption verification handshake.

Uses the MAC Merge Software Verification (mmsv) mechanism in ethtool
to perform the verification handshake for igc.
The structure fpe.mmsv is set by mmsv in ethtool and should remain
read-only for the driver.

Other mmsv callbacks:
a) configure_tx() -> not used yet at this point
- igc lacks registers to configure FPE in the transmit direction, so
this API is not utilized for now. When igc supports preemptible queue,
driver will use this API to manage its configuration.

b) configure_pmac() -> not used
- this callback dynamically controls pmac_enabled at runtime. For
example, mmsv calls configure_pmac() and disables pmac_enabled when
the link partner goes down, even if the user previously enabled it.
The intention is to save power but it is not feasible in igc
because it causes an endless adapter reset loop:

1) Board A and Board B complete the verification handshake. Tx mode
register for both boards are in TSN mode.
2) Board B link goes down.

On Board A:
3) mmsv calls configure_pmac() with pmac_enabled = false.
4) configure_pmac() in igc updates a new field based on pmac_enabled.
Driver uses this field in igc_tsn_new_flags() to indicate that the
user enabled/disabled FPE.
5) configure_pmac() in igc calls igc_tsn_offload_apply() to check
whether an adapter reset is needed. Calls existing logic in
igc_tsn_will_tx_mode_change() and igc_tsn_new_flags().
6) Since pmac_enabled is now disabled and no other TSN feature is
active, igc_tsn_will_tx_mode_change() evaluates to true because Tx
mode will switch from TSN to Legacy.
7) Driver resets the adapter.
8) Registers are set, and Tx mode switches to Legacy.
9) When link partner is up, steps 3-8 repeat, but this time with
pmac_enabled = true, reactivating TSN.
igc_tsn_will_tx_mode_change() evaluates to true again, since Tx
mode will switch from Legacy to TSN.
10) Driver resets the adapter.
11) Adapter reset completes, registers are set, and Tx mode switches to
TSN.

On Board B:
12) Adapter reset on Board A at step 10 causes it to detect its link
partner as down.
13) Repeats steps 3-8.
14) Once reset adapter on Board A is completed at step 11, it detects
its link partner as up.
15) Repeats steps 9-11.

- this cycle repeats indefinitely. To avoid this issue, igc only uses
mmsv.pmac_enabled to track whether FPE is enabled or disabled.

ixgbe: add device flash update via devlink

Use the pldmfw library to implement device flash update for
the Intel ixgbe networking device driver specifically for E610 devices.
This support uses the devlink flash update interface.

Using the pldmfw library, the provided firmware file will be scanned for
the three major components, "fw.undi" for the Option ROM, "fw.mgmt" for
the main NVM module containing the primary device firmware, and
"fw.netlist" containing the netlist module.

The flash is separated into two banks, the active bank containing the
running firmware, and the inactive bank which we use for update. Each
module is updated in a staged process. First, the inactive bank is
erased, preparing the device for update. Second, the contents of the
component are copied to the inactive portion of the flash. After all
components are updated, the driver signals the device to switch the
active bank during the next EMP reset.

With this implementation, basic flash update for the E610 hardware is
supported.

Merge tag 'net-next-6.15' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Jakub Kicinski:
"Core & protocols:

- Continue Netlink conversions to per-namespace RTNL lock
(IPv4 routing, routing rules, routing next hops, ARP ioctls)

- Continue extending the use of netdev instance locks. As a driver
opt-in protect queue operations and (in due course) ethtool
operations with the instance lock and not RTNL lock.

- Support collecting TCP timestamps (data submitted, sent, acked) in
BPF, allowing for transparent (to the application) and lower
overhead tracking of TCP RPC performance.

- Tweak existing networking Rx zero-copy infra to support zero-copy
Rx via io_uring.

- Optimize MPTCP performance in single subflow mode by 29%.

- Enable GRO on packets which went thru XDP CPU redirect (were queued
for processing on a different CPU). Improving TCP stream
performance up to 2x.

- Improve performance of contended connect() by 200% by searching for
an available 4-tuple under RCU rather than a spin lock. Bring an
additional 229% improvement by tweaking hash distribution.

- Avoid unconditionally touching sk_tsflags on RX, improving
performance under UDP flood by as much as 10%.

- Avoid skb_clone() dance in ping_rcv() to improve performance under
ping flood.

- Avoid FIB lookup in netfilter if socket is available, 20% perf win.

- Rework network device creation (in-kernel) API to more clearly
identify network namespaces and their roles. There are up to 4
namespace roles but we used to have just 2 netns pointer arguments,
interpreted differently based on context.

- Use sysfs_break_active_protection() instead of trylock to avoid
deadlocks between unregistering objects and sysfs access.

- Add a new sysctl and sockopt for capping max retransmit timeout in
TCP.

- Support masking port and DSCP in routing rule matches.

- Support dumping IPv4 multicast addresses with RTM_GETMULTICAST.

- Support specifying at what time packet should be sent on AF_XDP
sockets.

- Expose TCP ULP diagnostic info (for TLS and MPTCP) to non-admin
users.

- Add Netlink YAML spec for WiFi (nl80211) and conntrack.

- Introduce EXPORT_IPV6_MOD() and EXPORT_IPV6_MOD_GPL() for symbols
which only need to be exported when IPv6 support is built as a
module.

- Age FDB entries based on Rx not Tx traffic in VxLAN, similar to
normal bridging.

- Allow users to specify source port range for GENEVE tunnels.

- netconsole: allow attaching kernel release, CPU ID and task name to
messages as metadata

Driver API:

- Continue rework / fixing of Energy Efficient Ethernet (EEE) across
the SW layers. Delegate the responsibilities to phylink where
possible. Improve its handling in phylib.

- Support symmetric OR-XOR RSS hashing algorithm.

====================
ice, iavf: Add support for Rx timestamping

Mateusz Polchlopek says:

Initially, during VF creation it registers the PTP clock in
the system and negotiates with PF it's capabilities. In the
meantime the PF enables the Flexible Descriptor for VF.
Only this type of descriptor allows to receive Rx timestamps.

Enabling virtual clock would be possible, though it would probably
perform poorly due to the lack of direct time access.

Enable timestamping should be done using userspace tools, e.g.
hwstamp_ctl -i $VF -r 14

In order to report the timestamps to userspace, the VF extends
timestamp to 40b.

To support this feature the flexible descriptors and PTP part
in iavf driver have been introduced.

iavf: add initial framework for registering PTP clock

Add the iavf_ptp.c file and fill it in with a skeleton framework to
allow registering the PTP clock device.
Add implementation of helper functions to check if a PTP capability
is supported and handle change in PTP capabilities.
Enabling virtual clock would be possible, though it would probably
perform poorly due to the lack of direct time access.

Intel Wired LAN Driver Updates 2025-02-10 (ice, igc, e1000e)

For ice:

Karol, Jake, and Michal add PTP support for E830 devices. Karol
refactors and cleans up PTP code. Jake allows for a common
cross-timestamp implementation to be shared for all devices and
Michal adds E830 support.
