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).

tunnels
- nVidia/Mellanox:

- 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

table size, even when table is configured by the user

distribution

The sk_msg sg.copy bitmap is part of the scatterlist entry ownership
state. A set bit tells sk_msg_compute_data_pointers() not to expose the
entry through writable BPF ctx->data. This protects entries backed by
pages that are not private to the sk_msg, such as splice-backed file
page-cache pages.
Several sk_msg transform paths move, copy, split, or compact
msg->sg.data[] entries without moving the matching sg.copy bit. This can
make an externally backed entry arrive at a new slot with a clear copy
bit. A later SK_MSG verdict can then expose sg_virt(sge) as writable
ctx->data and BPF stores can modify the original page cache.
Keep sg.copy synchronized with sg.data[] whenever entries are
transferred, shifted, split, or copied into a new sk_msg. Clear the bit
when an entry is replaced by a newly allocated private page or freed.
This covers the BPF pull/push/pop helpers, sk_msg_shift_left/right(),
sk_msg_xfer(), and tls_split_open_record(), including the partial tail
entry created during TLS open-record splitting.

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.

AppleTalk keeps its per-interface control block (struct atalk_iface)
directly in struct netdevice (dev->atalk_ptr). This is the only thing
tying the protocol into the core net_device layout and is the sole
blocker to moving AppleTalk out of tree.
Replace dev->atalk_ptr with a small ifindex-keyed hashtable internal
to ddp.c. The existing atalk_interfaces list stays the owner of the iface
objects; the hashtable is purely a fast dev->iface index and reuses
the same atalk_interfaces_lock.
AFAICT this patch does not make this code any more racy than it already
is, I'm sure Sashiko will point out some basically existing bugs.
AFAICT atalk_interfaces_lock is the innermost lock already.

TLS and sockmap are now mutually exclusive. Try to delete the code
from sendmsg and recvmsg path which is now obviously dead.
The main goal is to delete enough code for AI security scanners
to no longer bother us with sockmap related bugs. At the same
time retain the code in case someone has the cycles to fix
all of this and make the integration work, again.
If the integration does not get restored we can wipe the rest
of the skmsg code from TLS in two or three releases.
The changes on the Tx side are deeper since that's where most
of the bugs are, Rx side simply takes the data from sockmap
and gives it to the user. On Tx split record handling and
rolling back the iterator were the two problem areas.

ATM removals have left a number of uAPI headers and ioctl
definitions with no in-kernel implementation behind them:
- device headers for adapters deleted with the legacy PCI/SBUS drivers:
atm_eni.h, atm_he.h, atm_idt77105.h, atm_nicstar.h, atm_zatm.h and
the atmtcp pair atm_tcp.h / <linux/atm_tcp.h>
- protocol headers for the removed CLIP, LANE and MPOA stacks:
atmarp.h, atmclip.h, atmlec.h, atmmpc.h
- atmsvc.h and the SVC / p2mp / local-address ioctls in atmdev.h
(ATM_{GET,RST,ADD,DEL}ADDR, ATM_{ADD,DEL,GET}LECSADDR,
ATM_{ADD,DROP}PARTY) left behind by the SVC and address-registry
removals
None of these are referenced by any remaining in-tree code.
Let's try to delete all this. Chances are nobody cares about
these headers any more. I'm keeping this separate from the
kernel side code changes for ease of revert, in case I am
proven wrong...

The PHY operations are vestiges of the SAR/framer split used by the
removed PCI/SBUS ATM adapters:
- atmdev_ops::phy_put / ::phy_get (register accessors) are never called
by the core and solos-pci only listed them as NULL
- struct atmphy_ops and atm_dev::phy have no users at all - nothing
assigns or dereferences them
Remove all of them. atm_dev::phy_data is kept: solos-pci repurposes it
to stash its per-port channel index.

atmdev_ops::pre_send (a TX pre-processing hook) and ::send_bh (a
bottom-half capable send variant) have no implementation behind them:
no remaining ATM driver sets either, so vcc_sendmsg() always skipped
pre_send and the raw AAL0/AAL5 paths always fell back to ->send().
The drivers that used these hooks were removed with the legacy ATM
adapters.
Drop both operations and the dead branches that tested for them.

atmdev_ops::change_qos() was the hook for renegotiating the traffic
parameters of an already-connected VCC, driven from SO_ATMQOS on a
connected socket (and previously from the SVC as_modify path, now gone).
None of the ATM drivers left in tree implement it - solos-pci only listed
change_qos = NULL - so atm_change_qos() always returned -EOPNOTSUPP.
Drop the operation and return -EOPNOTSUPP directly.

ATM switched virtual circuits (SVCs) are set up and torn down by a
user-space signaling daemon (atmsigd) which the kernel talks to over
a dedicated "sigd" socket: the kernel marshals Q.2931-style requests
(as_connect, as_listen, as_accept, as_close, ...) to the daemon and
applies the results to PF_ATMSVC sockets. This is the machinery behind
classical SVC use and was the foundation for LANE / MPOA, all of which
have been removed.
DSL deployments do not use any of this. PPPoATM and BR2684 run over
permanent virtual circuits (PF_ATMPVC) with a statically configured
VPI/VCI; no atmsigd, no Q.2931. Neither remaining ATM driver
(solos-pci, the USB DSL modems) is reachable through the SVC path.
Remove the SVC socket family and the signaling interface:
- delete net/atm/svc.c, net/atm/signaling.c and signaling.h
- drop atmsvc_init()/atmsvc_exit() and the PF_ATMSVC registration and
module alias
- drop the ATMSIGD_CTRL ioctl (sigd_attach) and the /proc/net/atm/svc
file
- fold the SVC branch out of atm_change_qos(); all sockets are PVCs now
The obsolete ATM_SETSC ioctl stub is left in place (it already just
warns and returns 0), as is the struct atm_vcc SVC bookkeeping shared
with the queueing layer.

net/atm/addr.c maintained the per-device lists of local NSAP addresses
(dev->local) and ILMI-learned LECS addresses (dev->lecs). These exist
solely to serve SVC signaling: the lists are populated through the
ATM_{ADD,DEL,RST}ADDR / ATM_{ADD,DEL,GET}LECSADDR ioctls used by the
atmsigd / ILMI daemons, and consumed when registering addresses with the
signaling daemon. The LECS list belonged to LAN Emulation, which has
been removed.
With no SVC users in a DSL-only configuration these lists are always
empty, so drop the registry entirely:
- remove the ADDR/LECSADDR/RSTADDR ioctls
- drop the now-always-empty "atmaddress" sysfs attribute
- remove the dev->local / dev->lecs lists, structs and enums
- delete net/atm/addr.c and net/atm/addr.h
The device ESI ("MAC" address) and its ATM_{G,S}ETESI ioctls and
"address" sysfs attribute are retained - the USB DSL modems populate
the ESI.

The atmdev_ops::send_oam device operation and the atm_vcc::push_oam
callback were the kernel's interface for raw F4/F5 OAM cell exchange.
Nothing assigns them a non-NULL value and nothing ever invokes them:
the core only ever initialises push_oam to NULL (in vcc_create() and the
AAL init helpers) and the Solos driver only lists send_oam = NULL for
documentation. The drivers that actually drove OAM through these hooks
were removed along with the legacy ATM adapters.
Drop both callbacks and the NULL initialisers.

were llist based, which is LIFO ordered, and hence each run had to do
an O(n) list reversal pass first to restore queue order.
Additionally, to cap the amount of task_work run, each method needed
a retry list as well.
Add a lockless MPCS FIFO queue (based on Dmitry Vyukov's intrusive
MPSC algorithm) and switch both task_work lists to it. It performs
better than llists and we can then also ditch the retry lists as well
as entries are popped one-at-the-time.
On top of those changes, run the tctx fallback task_work directly and
remove the now-unused per-ctx fallback machinery entirely.
- zcrx user notifications.
Add a mechanism for zcrx to communicate conditions back to userspace
via a dedicated CQE, with the initial users being notification on
running out of buffers and on a frag copy fallback, plus
shared-memory notification statistics.
Alongside that, a series of zcrx reliability and cleanup fixes: more
reliable scrubbing, poisoning pointers on unregistration, dropping an
extra ifq close, adding a ctx back-pointer, reordering fd allocation
in the export path, and killing a dead 'sock' member.
- Allow using io_uring registered buffers for plain SEND and RECV, not
just for the zero-copy send path.
This enables targets like ublk's NBD backend to push/pull IO data
directly to/from a registered buffer over a plain send/recv on a TCP
socket.
- Registered buffer improvements: account huge pages correctly, bump
the io_mapped_ubuf length field to size_t, and raise the previous 1GB
registered buffer size limit.
- Restrict the ctx access exposed to io_uring BPF struct_ops programs
by handing them an opaque type rather than the full io_ring_ctx, and
add a separate MAINTAINERS entry for the bpf-ops code.
- Allow opcode filtering on IORING_OP_CONNECT.
- Validate ring-provided buffer addresses with access_ok(), and align
the legacy buffer add limit with MAX_BIDS_PER_BGID.
- Various other cleanups and minor fixes, including avoiding msghdr
async data on connect/bind, dropping async_size for OP_LISTEN, making
the POLL_FIRST receive side checks consistent, re-checking
IO_WQ_BIT_EXIT for each linked work item, and using
trace_call__##name() at guarded tracepoint call sites.

Pull hfs/hfsplus updates from Viacheslav Dubeyko:
"Several fixes in HFS/HFS+ of syzbot reported issues and HFS//HFS+
fixes of xfstests failures.
- fix a null-ptr-deref issue reported by syzbot (Edward Adam Davis)
If the attributes file is not loaded during system mount
hfsplus_create_attributes_file can dereference a NULL pointer.
Also, add a b-tree node size check in hfs_btree_open() with the
goal to prevent an uninit-value bug reported by syzbot for the case
of corrupted HFS+ image.
- fix __hfs_bnode_create() by using kzalloc_flex() instead of
kzalloc() (Rosen Penev)
- fix early return in hfs_bnode_read() (Tristan Madani)
hfs_bnode_read() can return early without writing to the output
buffer when is_bnode_offset_valid() fails or when
check_and_correct_requested_ length() corrects the length to zero.
Callers such as hfs_bnode_read_ u16() and hfs_bnode_read_u8() pass
stack-allocated buffers and use the result unconditionally, leading
to KMSAN uninit-value reports.
The rest fix (1) generic/637, generic/729 issue for the case of HFS+
file system, (2) generic/003, generic/637 for the case of HFS file
system"

Implement the DSA .port_vlan_add and .port_vlan_del operations to enable
VLAN-aware bridge offloading on the NETC switch.
VLAN membership is maintained in the VLAN Filter Table (VFT). Adding the
first port to a VLAN creates a new VFT entry with hardware MAC learning
and flood-on-miss forwarding; subsequent ports update the existing
entry's membership bitmap. Removing the last port deletes the entry.
Egress tagging is handled through the Egress Treatment Table (ETT). Each
VLAN is allocated a group of ETT entries, one per available port. Ports
are assigned a sequential ett_offset during initialisation, used to
address each port's entry within the group. Untagged ports configure the
ETT to strip the outer VLAN tag; tagged ports pass frames through
unmodified. Each ETT group is optionally paired with an Egress Counter
Table (ECT) group for per-port frame counting, allocated on a best-effort
basis. When the egress rule of an ETT entry changes, the counter of the
corresponding ECT entry will be recounted to track the number of frames
that match the new egress rule.
A software shadow list serialised by vft_lock tracks active VLAN state
across both port membership and egress tagging. VID 0 is used for single
port mode and is ignored by both callbacks.

NTMP index tables require software to allocate and manage entry IDs.
Add two bitmap helper functions to facilitate this management:
ntmp_lookup_free_eid(): finds the first zero bit in the given bitmap,
sets it to mark the entry as in-use, and returns the corresponding entry
ID. Returns NTMP_NULL_ENTRY_ID if no free entry is available.
ntmp_clear_eid_bitmap(): clears the bit associated with the given entry
ID in the bitmap to mark the entry as free. It is a no-op if the entry
ID is NTMP_NULL_ENTRY_ID.
Both functions are exported for use by other modules, such as the NETC
switch driver which needs to manage group index bitmaps for the Egress
Treatment Table (ETT) and Egress Count Table (ECT).

The Egress Treatment Table (ETT) and Egress Count Table (ECT) are both
index tables whose entry IDs are allocated by software. Every num_ports
entries form a group, where each entry in the group corresponds to one
port. To facilitate group allocation and management, initialize the group
index bitmaps for both tables based on hardware capabilities reported by
ETTCAPR and ECTCAPR registers.
The bitmap size per table is calculated as the total number of hardware
entries divided by the number of available ports, which gives the number
of groups available for software allocation. A set bit in the bitmap
represents a group index that has been allocated.
These bitmaps will be used by subsequent patches that add VLAN support.

The egress count table is a static bounded index table, egress related
statistics are maintained in this table. The table is implemented as a
linear array of entries accessed using an index (0, 1, 2, ..., n) that
uniquely identifies an entry within the array. Egress Counter Entry ID
(EC_EID) is used as an index to an entry in this table. The EC_EID is
specified in the egress treatment table.
Egress count table entries are always present and enabled. The table
only supports access via entry ID, which is assigned by the software.
And it supports Update, Query and Query followed by Update operations.
Currently, only Update operation is supported.

Each entry in the egress treatment table contains the egress packet
processing actions to be applied to a grouping or scope of packets
exiting on a particular egress port of the switch. A scope of packets,
for example, could be the packets exiting a particular VLAN, matching
a particular 802.1Q bridge forwarding entry or belonging to a stream
identified at ingress. The egress treatment table is implemented as a
linear array of entries accessed using an index (0,1, 2, ..., n) that
uniquely identifies an entry within the array.
The egress treatment table only supports access vid entry ID, which is
assigned by the software. It supports Add, Update, Delete and Query
operations. Note that only Query operation is not supported yet.

ntmp_vft_update_entry(): Update the configuration element data of the

ntmp_vft_delete_entry(): Delete the VLAN filter entry corresponding to

Add three interfaces to manage dynamic entries in the FDB table:
ntmp_fdbt_update_activity_element(): Update the activity element of all
dynamic FDB entries. For each entry, if its activity flag is not set,
which means no packet has matched this entry since the last update, the
activity counter is incremented. Otherwise, both the activity flag and
activity counter are reset. The activity counter is used to track how
long an FDB entry has been inactive, which is useful for implementing
an ageing mechanism.
ntmp_fdbt_delete_ageing_entries(): Delete all dynamic FDB entries whose
activity flag is not set and whose activity counter is greater than or
equal to the specified threshold. This is used to remove stale entries
that have been inactive for too long.
ntmp_fdbt_delete_port_dynamic_entries(): Delete all dynamic FDB entries
associated with the specified switch port. This is typically called when
a port goes down or is removed from a bridge.

Pull locking updates from Ingo Molnar:
"Futex updates:
- Optimize futex hash bucket access patterns (Peter Zijlstra)
- Large series to address the robust futex unlock race for real, by
Thomas Gleixner:
"The robust futex unlock mechanism is racy in respect to the
clearing of the robust_list_head::list_op_pending pointer because
unlock and clearing the pointer are not atomic.
The race window is between the unlock and clearing the pending op
pointer. If the task is forced to exit in this window, exit will
access a potentially invalid pending op pointer when cleaning up
the robust list.
That happens if another task manages to unmap the object
containing the lock before the cleanup, which results in an UAF.
In the worst case this UAF can lead to memory corruption when
unrelated content has been mapped to the same address by the time
the access happens.
User space can't solve this problem without help from the kernel.
This series provides the kernel side infrastructure to help it
along:
1) Combined unlock, pointer clearing, wake-up for the
contended case
2) VDSO based unlock and pointer clearing helpers with a
fix-up function in the kernel when user space was interrupted
within the critical section.

Pull timekeeping updates from Thomas Gleixner:
"Updates for NTP/timekeeping and PTP:
- Expand timekeeping snapshot mechanisms
The various snapshot functions are mostly used for PTP to collect
"atomic" snapshots of various involved clocks.
They lack support for the recently introduced AUX clocks and do not
provide the underlying counter value (e.g. TSC) to user space.
Exposing the counter value snapshot allows for better control and
steering.
Convert the hard wired ktime_get_snapshot() to take a clock ID,
which allows the caller to select the clock ID to be captured along
with CLOCK_MONONOTONIC_RAW. Additionally capture the underlying
hardware counter value and the clock source ID of the counter.
Expand the hardware based snapshot capture where devices provide a
mechanism to snapshot the hardware PTP clock and the system counter
(usually via PCI/PTM) to support AUX clocks and also provide the
captured counter value back to the caller and not only the clock
timestamps derived from it.
- Add a new optional read_snapshot() callback to clocksources
That is required to capture atomic snapshots from clocksources
which are derived from TSC with a scaling mechanism (e.g. Hyper-V,
KVMclock).
The value pair is handed back in the snapshot structure to the
callers, so they can do the necessary correlations in a more
precise way.
This touches usage sites of the affected functions and data structure
all over the tree, but stays fully backwards compatible for the
existing user space exposed interfaces. New PTP IOCTLs will provide
access to the extended functionality in later kernel versions"

Pull NOHZ updates from Thomas Gleixner:
- Fix a long standing TOCTOU in get_cpu_sleep_time_us()
- Make the CPU offline NOHZ handling more robust by disabling NOHZ on
the outgoing CPU early instead of creating unneeded state which needs
to be undone.
- Unify idle CPU time accounting instead of having two different
accounting mechanisms. These two different mechanisms are not really
independent, but the different properties can in the worst case cause
that gloabl idle time can be observed going backwards.
- Consolidate the idle/iowait time retrieval interfaces instead of
converting back and forth between them.
- Make idle interrupt time accounting more robust. The original code
assumes that interrupt time accouting is enabled and therefore stops
elapsing idle time while an interrupt is handled in NOHZ dyntick
state. That assumption is not correct as interrupt time accounting
can be disabled at compile and runtime.
- Fix an accounting error between dyntick idle time and dyntick idle
steal time. The stolen time is not accounted and therefore idle time
becomes inaccurate. The stolen time is now accounted after the fact
as there is no way to predict the steal time upfront.

Pull timer core updates from Thomas Gleixner:
"Updates for the time/timer core subsystem:
- Harden the user space controllable hrtimer interfaces further to
protect against unpriviledged DoS attempts by arming timers in the
past.
- Add per-capacity hierarchies to the timer migration code to prevent
timer migration accross different capacity domains. This code has
been disabled last minute as there is a pathological problem with
SoCs which advertise a larger number of capacity domains. The
problem is under investigation and the code won't be active before
v7.3, but that turned out to be less intrusive than a full revert
as it preserves the preparatory steps and allows people to work on
the final resolution
- Export time namespace functionality as a recent user can be built
as a module.
- Initialize the jiffies clocksource before using it. The recent
hardening against time moving backward requires that the related
members of struct clocksource have been initialized, otherwise it
clamps the readout to 0, which makes time stand sill and causes
boot delays.
- Fix a more than twenty year old PID reference count leak in an
error path of the POSIX CPU timer code.
- The usual small fixes, improvements and cleanups all over the
place"
