Pull networking fixes from Jakub Kicinski:
"Including fixes from IPSec, netfilter and Bluetooth.

Nothing really stands out, but as usual there's a slight concentration
of fixes for issues added in the last two weeks before the merge
window, and driver bugs from 6.13 which tend to get discovered upon
wider distribution.

Current release - regressions:

- net: revert RTNL changes in unregister_netdevice_many_notify()

- Bluetooth: fix possible infinite recursion of btusb_reset

- eth: adjust locking in some old drivers which protect their state
with spinlocks to avoid sleeping in atomic; core protects netdev
state with a mutex now

Previous releases - regressions:

- eth:
- mlx5e: make sure we pass node ID, not CPU ID to kvzalloc_node()
- bgmac: reduce max frame size to support just 1500 bytes; the
jumbo frame support would previously cause OOB writes, but now
fails outright

- mptcp: blackhole only if 1st SYN retrans w/o MPC is accepted, avoid
false detection of MPTCP blackholing

Previous releases - always broken:

- mptcp: handle fastopen disconnect correctly

- xfrm:
- make sure skb->sk is a full sock before accessing its fields
- fix taking a lock with preempt disabled for RT kernels

- usb: ipheth: improve safety of packet metadata parsing; prevent
potential OOB accesses

- eth: renesas: fix missing rtnl lock in suspend/resume path"

Merge tag 'net-next-6.14' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Paolo Abeni:
"This is slightly smaller than usual, with the most interesting work
being still around RTNL scope reduction.

Core:

- More core refactoring to reduce the RTNL lock contention, including
preparatory work for the per-network namespace RTNL lock, replacing
RTNL lock with a per device-one to protect NAPI-related net device
data and moving synchronize_net() calls outside such lock.

- Extend drop reasons usage, adding net scheduler, AF_UNIX, bridge
and more specific TCP coverage.

- Reduce network namespace tear-down time by removing per-subsystems
synchronize_net() in tipc and sched.

- Add flow label selector support for fib rules, allowing traffic
redirection based on such header field.

Netfilter:

- Do not remove netdev basechain when last device is gone, allowing
netdev basechains without devices.

- Revisit the flowtable teardown strategy, dealing better with fin,
reset and re-open events.

- Scale-up IP-vs connection dumping by avoiding linear search on each
restart.

Protocols:

- A significant XDP socket refactor, consolidating and optimizing
several helpers into the core

- Better scaling of ICMP rate-limiting, by removing false-sharing in
inet peers handling.

- Introduces netlink notifications for multicast IPv4 and IPv6
address changes.

- Add ipsec support for IP-TFS/AggFrag encapsulation, allowing
aggregation and fragmentation of the inner IP.

- Add sysctl to configure TIME-WAIT reuse delay for TCP sockets, to
avoid local port exhaustion issues when the average connection
lifetime is very short.

- Support updating keys (re-keying) for connections using kernel TLS
(for TLS 1.3 only).

- Support ipv4-mapped ipv6 address clients in smc-r v2.

- Add support for jumbo data packet transmission in RxRPC sockets,
gluing multiple data packets in a single UDP packet.

- Support RxRPC RACK-TLP to manage packet loss and retransmission in
conjunction with the congestion control algorithm.

Driver API:

- Introduce a unified and structured interface for reporting PHY
statistics, exposing consistent data across different H/W via
ethtool.

- Make timestamping selectable, allow the user to select the desired
hwtstamp provider (PHY or MAC) administratively.

- Add support for configuring a header-data-split threshold (HDS)
value via ethtool, to deal with partial or buggy H/W
implementation.

- Consolidate DSA drivers Energy Efficiency Ethernet support.

- Add EEE management to phylink, making use of the phylib
implementation.

- Add phylib support for in-band capabilities negotiation.

- Simplify how phylib-enabled mac drivers expose the supported
interfaces.

Tests and tooling:

- Make the YNL tool package-friendly to make it easier to deploy it
separately from the kernel.

- Increase TCP selftest coverage importing several packetdrill
test-cases.

- Regenerate the ethtool uapi header from the YNL spec, to ease
maintenance and future development.

- Add YNL support for decoding the link types used in net self-tests,
allowing a single build to run both net and drivers/net.

Merge branch 'net-add-phylink-managed-eee-support'

Russell King says:

====================
net: add phylink managed EEE support

Adding managed EEE support to phylink has been on the cards ever since
the idea in phylib was mooted. This overly large series attempts to do
so. I've included all the patches as it's important to get the driver
patches out there.

Patch 1 adds a definition for the clock stop capable bit in the PCS
MMD status register.

Patch 2 adds a phylib API to query whether the PHY allows the transmit
xMII clock to be stopped while in LPI mode. This capability is for MAC
drivers to save power when LPI is active, to allow them to stop their
transmit clock.

Patch 3 extracts a phylink internal helper for determining whether the
link is up.

Patch 4 adds basic phylink managed EEE support. Two new MAC APIs are
added, to enable and disable LPI. The enable method is passed the LPI
timer setting which it is expected to program into the hardware, and
also a flag ehther the transmit clock should be stopped.

I have taken the decision to make enable_tx_lpi() to return an error
code, but not do much with it other than report it - the intention
being that we can later use it to extend functionality if needed
without reworking loads of drivers.

I have also dropped the validation/limitation of the LPI timer, and
left that in the driver code prior to calling phylink_ethtool_set_eee().

The remainder of the patches convert mvneta, lan743x and stmmac, and
add support for mvneta.

net: mvneta: convert to phylink EEE implementation

Convert mvneta to use phylink's EEE implementation by implementing the
two LPI control methods, and adding the initial configuration and
capabilities.

Although disabling LPI requires clearing a single bit, for safety we
clear the manual mode and force bits to ensure that auto mode will be
used.

Enabling LPI needs a full configuration of several values, as the timer
values are dependent on the MAC operating speed, as per the original
code.

As Armada 388 states that EEE is only supported in "SGMII" modes, mark
this in lpi_interfaces. Testing with RGMII on the Clearfog platform
indicates that the receive path fails to detect LPI over RGMII.

Wrap napi_enable() / napi_disable() with netdev_lock().

iavf needs the usual adjustment. A number of drivers call
napi_enable() under a spin lock, so they have to be modified
to take netdev_lock() first, then spin lock then call
napi_enable_locked().

Protecting napi_enable() implies that napi->napi_id is protected
by netdev_lock().

Merge branch 'net-phylink-fix-pcs-without-autoneg'

Russell King says:

====================
net: phylink: fix PCS without autoneg

Eric Woudstra reported that a PCS attached using 2500base-X does not
see link when phylink is using in-band mode, but autoneg is disabled,
despite there being a valid 2500base-X signal being received. We have
these settings:

act_link_an_mode = MLO_AN_INBAND
pcs_neg_mode = PHYLINK_PCS_NEG_INBAND_DISABLED

Eric diagnosed it to phylink_decode_c37_word() setting state->link
false because the full-duplex bit isn't set in the non-existent link
partner advertisement word (which doesn't exist because in-band
autoneg is disabled!)

The test in phylink_mii_c22_pcs_decode_state() is supposed to catch
this state, but since we converted PCS to use neg_mode, testing the
Autoneg in the local advertisement is no longer sufficient - we need
to be looking at the neg_mode, which currently isn't provided.

We need to provide this via the .pcs_get_state() method, and this
will require modifying all PCS implementations to add the extra
argument to this method.

Patch 1 uses the PCS neg_mode in phylink_mac_pcs_get_state() to correct
the now obsolute usage of the Autoneg bit in the advertisement.

Patch 2 passes neg_mode into the .pcs_get_state() method, and updates
all users.

Patch 3 adds neg_mode as an argument to the various clause 22 state
decoder functions in phylink, modifying drivers to pass the neg_mode
through.

Patch 4 makes use of phylink_mii_c22_pcs_decode_state() rather than
using the Autoneg bit in the advertising field.

Patch 5 may be required for Eric's case - it ensures that we report
the correct state for interface types that we support only one set
of modes for when autoneg is disabled.

Merge branch 'net-add-negotiation-of-in-band-capabilities'

Russell King says:

====================
net: add negotiation of in-band capabilities

This is a repost without RFC for this series, shrunk down to 13 patches
by removing the non-Marvell PCS.

Phylink's handling of in-band has been deficient for a long time, and
people keep hitting problems with it. Notably, situations with the way-
to-late standardized 2500Base-X and whether that should or should not
have in-band enabled. We have also been carrying a hack in the form of
phylink_phy_no_inband() for a PHY that has been used on a SFP module,
but has no in-band capabilities, not even for SGMII.

When phylink is trying to operate in in-band mode, this series will look
at the capabilities of the MAC-side PCS and PHY, and work out whether
in-band can or should be used, programming the PHY as appropriate. This
includes in-band bypass mode at the PHY.

We don't... yet... support bypass on the MAC side PCS, because that
requires yet more complexity.

Patch 1 passes struct phylink and struct phylink_pcs into
phylink_pcs_neg_mode() so we can look at more state in this function in
a future patch.

Patch 2 splits "cur_link_an_mode" (the MLO_AN_* mode) into two separate
purposes - a requested and an active mode. The active mode is the one
we will be using for the MAC, which becomes dependent on the result of
in-band negotiation.

Patch 3 adds debug to phylink_major_config() so we can see what is going
on with the requested and active AN modes.

Patch 4 adds to phylib a method to get the in-band capabilities of the
PHY from phylib. Patches 5 and 6 add implementations for BCM84881 and
some Marvell PHYs found on SFPs.

Patch 7 adds to phylib a method to configure the PHY in-band signalling,
and patch 8 implements it for those Marvell PHYs that support the method
in patch 4.

Patch 9 does the same as patch 4 but for the MAC-side PCS, with patches
10 and 11 adding support to Marvell NETA and PP2.

Patch 12 adds the code to phylink_pcs_neg_mode() which looks at the
capabilities, and works out whether to use in-band or out-band mode for
driving the link between the MAC PCS and PHY.

Patch 13 removes the phylink_phy_no_inband() hack now that we are
publishing the in-band capabilities from the BCM84881 PHY driver.

Three more PCS, omitted from this series due to the limit of 15 patches,
will be sent once this has been merged.

Pull networking updates from Paolo Abeni:
"The most significant set of changes is the per netns RTNL. The new
behavior is disabled by default, regression risk should be contained.

Notably the new config knob PTP_1588_CLOCK_VMCLOCK will inherit its
default value from PTP_1588_CLOCK_KVM, as the first is intended to be
a more reliable replacement for the latter.

Core:

- Started a very large, in-progress, effort to make the RTNL lock
scope per network-namespace, thus reducing the lock contention
significantly in the containerized use-case, comprising:
- RCU-ified some relevant slices of the FIB control path
- introduce basic per netns locking helpers
- namespacified the IPv4 address hash table
- remove rtnl_register{,_module}() in favour of
rtnl_register_many()
- refactor rtnl_{new,del,set}link() moving as much validation as
possible out of RTNL lock
- convert all phonet doit() and dumpit() handlers to RCU
- convert IPv4 addresses manipulation to per-netns RTNL
- convert virtual interface creation to per-netns RTNL
the per-netns lock infrastructure is guarded by the
CONFIG_DEBUG_NET_SMALL_RTNL knob, disabled by default ad interim.

- Introduce NAPI suspension, to efficiently switching between busy
polling (NAPI processing suspended) and normal processing.

- Migrate the IPv4 routing input, output and control path from direct
ToS usage to DSCP macros. This is a work in progress to make ECN
handling consistent and reliable.

- Add drop reasons support to the IPv4 rotue input path, allowing
better introspection in case of packets drop.

- Make FIB seqnum lockless, dropping RTNL protection for read access.

- Make inet{,v6} addresses hashing less predicable.

- Allow providing timestamp OPT_ID via cmsg, to correlate TX packets
and timestamps

Things we sprinkled into general kernel code:

- Add small file operations for debugfs, to reduce the struct ops
size.

- Refactoring and optimization for the implementation of page_frag
API, This is a preparatory work to consolidate the page_frag
implementation.

Netfilter:

- Optimize set element transactions to reduce memory consumption

- Extended netlink error reporting for attribute parser failure.

- Make legacy xtables configs user selectable, giving users the
option to configure iptables without enabling any other config.

- Address a lot of false-positive RCU issues, pointed by recent CI
improvements.

BPF:

- Put xsk sockets on a struct diet and add various cleanups. Overall,
this helps to bump performance by 12% for some workloads.

- Extend BPF selftests to increase coverage of XDP features in
combination with BPF cpumap.

- Optimize and homogenize bpf_csum_diff helper for all archs and also
add a batch of new BPF selftests for it.

- Extend netkit with an option to delegate skb->{mark,priority}
scrubbing to its BPF program.

- Make the bpf_get_netns_cookie() helper available also to tc(x) BPF
programs.

Protocols:

- Introduces 4-tuple hash for connected udp sockets, speeding-up
significantly connected sockets lookup.

- Add a fastpath for some TCP timers that usually expires after
close, the socket lock contention.

- Add inbound and outbound xfrm state caches to speed up state
lookups.

- Avoid sending MPTCP advertisements on stale subflows, reducing
risks on loosing them.

- Make neighbours table flushing more scalable, maintaining per
device neigh lists.

Driver API:

- Introduce a unified interface to configure transmission H/W
shaping, and expose it to user-space via generic-netlink.

- Add support for per-NAPI config via netlink. This makes napi
configuration persistent across queues removal and re-creation.
Requires driver updates, currently supported drivers are:
nVidia/Mellanox mlx4 and mlx5, Broadcom brcm and Intel ice.

- Add ethtool support for writing SFP / PHY firmware blocks.

- Track RSS context allocation from ethtool core.

- Implement support for mirroring to DSA CPU port, via TC mirror
offload.

- Consolidate FDB updates notification, to avoid duplicates on
device-specific entries.

- Expose DPLL clock quality level to the user-space.

- Support master-slave PHY config via device tree.

Tests and tooling:

- forwarding: introduce deferred commands, to simplify the cleanup
phase

Drivers:

- Updated several drivers - Amazon vNic, Google vNic, Microsoft vNic,
Intel e1000e and Broadcom Tigon3 - to use netdev-genl to link the
IRQs and queues to NAPI IDs, allowing busy polling and better
introspection.
