Pull networking updates from Jakub Kicinski:
"Core & protocols:
- Work on removing rtnl_lock protection throughout the stack
continues. In this chapter:
- don't use rtnl_lock for IPv6 multicast routing configuration
- don't take rtnl_lock in ethtool for modern drivers
- prepare Qdisc dump callbacks for rtnl_lock removal
- Support dumping just ifindex + name of all interfaces, under RCU.
It's a common operation for Netlink CLI tools (when translating
names to ifindexes) and previously required full rtnl_lock.
- Support dumping qdiscs and page pools for a specific netdev. Even
tho user space wants a dump of all netdevs, most of the time, the
OOO programming model results in repeating the dump for each
netdev. Which, in absence of a cache, leads to a O(n^2) behavior.
- Flush nexthops once on multi-nexthop removal (e.g. when device goes
down), another O(n^2) -> O(n) improvement.
- Rehash locally generated traffic to a different nexthop on
retransmit timeout.
- Honor oif when choosing nexthop for locally generated IPv6 traffic.
- Convert TCP Auth Option to crypto library, and drop non-RFC algos.
- Increase subflow limits in MPTCP to 64 and endpoint limit to 256.
- Support MPTCP signaling of IPv6 address + port (ADD_ADDR). We need
to selectively skip reporting of the standard TCP Timestamp option,
because they won't fit into the header space together (12 + 30 >
40).
- Support using bridge neighbor suppression, Duplicate Address
Detection, Gratuitous ARP and unsolicited NA forwarding - in EVPN
deployments, e.g. VXLAN fabrics (IPv4 and IPv6).
- Improve link state reporting for upper netdevs (e.g. macvlan) over
tunnel devices (again, mostly for EVPN deployments).
- Support binding GENEVE tunnels to a local address.
- Speed up UDP tunnel destruction (remove one synchronize_rcu()).
- Support exponential field encoding in multicast (IGMPv3 and MLDv2).
- Support attaching PSP crypto offload to containers (veth, netkit).
- Add a new IPSec Netlink message XFRM_MSG_MIGRATE_STATE that allows
migrating individual IPsec SAs independently of their policies.
The existing XFRM_MSG_MIGRATE is tightly coupled to policy+SA
migration, lacks SPI for unique SA identification, and cannot
express reqid changes or migrate Transport mode selectors.
The new interface identifies the SA via SPI and mark, supports
reqid changes, address family changes, encap removal, and uses an
atomic create+install flow under x->lock to prevent SN/IV reuse
during AEAD SA migration.
- Implement GRO/GSO support for PPPoE.
- Convert sockopt callbacks in a number of protocols to iov_iter.
Cross-tree stuff:
- Remove support for Crypto TFM cloning (unblocked after the TCP Auth
Option rework). This feature regressed performance for all crypto
API users, since it changed crypto transformation objects into
reference-counted objects.
- Add FCrypt-PCBC implementation to rxrpc and remove it from the
global crypto API as obsolete and insecure.
Wireless:
- Major rework of station bandwidth handling, fixing issues with
lower capability than AP.
- Cleanups for EMLSR spec issues (drafts differed).
- More Neighbor Awareness Networking (Wi-Fi Aware) work (multicast,
schedule improvements, multi-station etc.)
- Some Ultra High Reliability (UHR) / IEEE 802.11bn (D1.4) work
(e.g. non-primary channel access, UHR DBE support).
- Fine Timing Measurement ranging (i.e. distance measurement) APIs.
Netfilter:
- Use per-rule hash initval in nf_conncount. This avoids unnecessary
lock contention with short keys (e.g. conntrack zones) in different
namespaces.
- Various safety improvements, both in packet parsing and object
lifetimes. Notably add refcounts to conntrack timeout policy.
Deletions:
- Remove TLS + sockmap integration. TLS wants to pin user pages to
avoid a copy, and sockmap wants to write to the input stream. More
work on this integration is clearly needed, and we can't find any
users (original author admitted that they never deployed it).
- Remove support for TLS offload with TCP Offload Engine (the far
more common opportunistic offload is retained). The locking looks
unfixable (driver sleeps under TCP spin locks) and people from the
vendor that added this are AWOL.
- Remove more ATM code, trying to leave behind only what PPPoATM
needs, AAL5 and br2684 with permanent circuits.
- Remove AppleTalk. Let it join hamradio in our out of tree protocol
graveyard, I mean, repository.
- Disable 32-bit x_tables compatibility (32bit binaries on 64bit
kernel) interface in user namespaces. To be deleted completely,
soon.
- Remove 5/10 MHz support from cfg80211/mac80211.
Drivers:
- Software:
- Support DEVMEM/DMABUF Tx over NETMEM_TX_NO_DMA devices (netkit)
- bonding: add knob to strictly follow 802.3ad for link state
- New drivers:
- Alibaba Elastic Ethernet Adaptor (cloud vNIC).
- NXP NETC switch within i.MX94.
- DPLL:

configuration
- support Socket Direct (multi-PF) with switchdev offloads
- add a pool / frag allocator for DMA mapped buffers for
control objects, save memory on systems with 64kB page size

Introduce a driver for the networking lanes of the 10G Lynx SerDes
block, present on the majority of Layerscape and QorIQ (Freescale/NXP)
SoCs.
As with the 28G Lynx, the SerDes lanes come pre-initialized out of
reset and the consumers use them that way outside the Generic PHY
framework (for networking, the static configuration remains for the
entire SoC lifetime, whereas for SATA and PCIe, the hardware
reconfigures itself automatically for other link speeds).
The need for the Generic PHY framework comes specifically for networking
use cases where a static lane configuration is not sufficient. For
example a network MAC is connected to an SFP cage, where various SFP or
SFP+ modules can be connected. Each of them may require a different
SerDes protocol (SGMII, 1000Base-X, 10GBase-R), which phylink + sfp-bus
are responsible of figuring out. The phylink drivers are:
- enetc
- felix
- dpaa_eth (fman_memac)
- dpaa2-eth
- dpaa2-switch
and they all need to reconfigure the SerDes for the requested link mode,
using phy_set_mode_ext() (and phy_validate() to see if it is supported
in the first place).
Note that SerDes 2 on LS1088A is exclusively non-networking, so there is
currently no need for this driver. Therefore we skip matching on its
compatible string and do not probe on that device.

Do some preparation work for the introduction of the lynx-10g driver,
which will share a common backbone with the 28G Lynx SerDes.
This is just trivial stuff which can be moved without any surgery, and
is easy to follow but otherwise pollutes more serious changes.
The lane modes themselves are exported to a public header, because on
the 10G Lynx, the hardware requires implementing a procedure called
"RCW override". This requires coordination with drivers/soc/fsl/guts.c
to tell it that a SerDes lane needs to be switched to a different
protocol (enum lynx_lane_mode).

The .netdev_to_port() currently takes only a net_device and returns the
port index, without verifying the netdev actually belongs to the switch
being operated on. This can cause flower rule parsing to silently
resolve to a wrong port on the local hardware.
Update both implementations felix_netdev_to_port() and
ocelot_netdev_to_port() to validate ownership. Also update the callers
in ocelot_flower.c to pass through the ocelot context.

The bulk of these changes converts existing users to the modern variants
of the API that take a PMC instance as argument. This completes the
transition to multi-instance support, which then makes room for cleanups
and restricting the remaining legacy APIs to 32-bit platforms.
Some changes in this set also clean up powergate debugfs and restrict
the power-off handler to be installed only where appropriate. Lastly,

tegra186_mc_resume() is the only implementation of the SoC ->resume()
op in struct tegra_mc_ops, and it can never fail as the SID override
loop has no error path. The int return value is therefore not used.
Change the prototype to return void so callers do not need to deal
with a value that is always 0. If a future SoC needs to report
failure from resume, an int return type can be reintroduced then.

firmware: tegra: Changes for v7.1-rc1

DT when getting a reference from a phandle. This is used to reference
specific instances of the PCI controller on Tegra264. The ABI header for
BPMP is updated to the latest version and BPMP APIs now use the more
intuitive ENODEV instead of the non SUSV4 ENOTSUPP error code for stub
implementations.
