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:
- Add operational state to pins (implement in zl3073x).
- Add generic DPLL type, for daisy-chaining DPLLs (implement in ice).

- Ethernet high-speed NICs:
- Huawei (hinic3):
- enhance tc flow offload support with queue selection,
tunnels
- nVidia/Mellanox:
- avoid over-copying payload to the skb's linear part (up to
60% win for LRO on slow CPUs like ARM64 V2)
- expose more per-queue stats over the standard API
- support additional, unprivileged PFs in the DPU
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
- take advantage of the ability to dynamically change RSS
table size, even when table is configured by the user
- increase the max RSS table size for even traffic
distribution

appletalk: move the protocol out of tree

2026-06-16T21:37:06+00:00

AppleTalk has been removed in MacOS X 10.6 (Snow Leopard), in 2009,
according to Wikipedia. We recently got a burst of AI generated
fixes to this protocol which nobody is reviewing.

Let AppleTalk follow AX.25 and hamradio out of the Linux tree.
We we will maintain the code at: github.com/linux-netdev/mod-orphan
for anyone interested in playing with it.

Retain the uAPI for now. No strong reason, simply because I suspect
keeping it will be less controversial.

crypto: pcbc - Remove support for PCBC mode

2026-06-10T00:03:03+00:00

The only user of PCBC mode (Propagating Cipher Block Chaining mode) was
net/rxrpc/rxkad.c, which now uses local code instead.

While PCBC was an interesting cryptographic experiment, it has largely
been relegated to the history books and academic exercises.  It is
non-parallelizable (i.e., very slow) and doesn't actually achieve the
integrity properties it was apparently intended to achieve.

Remove support for it from the crypto API.

crypto: fcrypt - Remove support for FCrypt block cipher

2026-06-10T00:03:03+00:00

Remove the insecure FCrypt block cipher from the crypto API.  Its only
user was net/rxrpc/, but now net/rxrpc/ implements it locally.  The
crypto API implementation is no longer needed.

For some additional context: FCrypt was designed in 1988 and is
essentially a weakened version of DES.  It has the same 56-bit key size
as DES, which is easily brute forced.  Moreover, it's cryptographically
weak and doesn't even provide the intended 56-bit security level.  Its
author considers it to be a mistake, as well
(https://lists.openafs.org/pipermail/openafs-devel/2000-December/005320.html).

But fortunately this 1980s-era homebrew block cipher was never adopted
outside of net/rxrpc/.  So its code can just be kept there.

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

   - Support HW queue leasing, allowing containers to be granted access
     to HW queues for zero-copy operations and AF_XDP

   - Number of code moves to help the compiler with inlining. Avoid
     output arguments for returning drop reason where possible

   - Rework drop handling within qdiscs to include more metadata about
     the reason and dropping qdisc in the tracepoints

   - Remove the rtnl_lock use from IP Multicast Routing

   - Pack size information into the Rx Flow Steering table pointer
     itself. This allows making the table itself a flat array of u32s,
     thus making the table allocation size a power of two

   - Report TCP delayed ack timer information via socket diag

crypto: Remove michael_mic from crypto_shash API

2026-04-08T08:11:37+00:00

Remove the "michael_mic" crypto_shash algorithm, since it's no longer
used.  Its only users were wireless drivers, which have now been
converted to use the michael_mic() function instead.

It makes sense that no other users ever appeared: Michael MIC is an
