net: ip_gre: require CAP_NET_ADMIN in the device netns for changelink
A tunnel changelink() operates on at most two netns, dev_net(dev) and the tunnel link netns t->net. They differ once the device is created in or moved to a netns other than the one the request runs in. The rtnl changelink path checks CAP_NET_ADMIN only against dev_net(dev), so a caller privileged there but not in t->net can rewrite a tunnel that lives in t->net. Add rtnl_dev_link_net_capable() next to rtnl_get_net_ns_capable() in net/core/rtnetlink.c. It requires CAP_NET_ADMIN in the link netns and is skipped when the link netns is dev_net(dev), where the rtnl path already checked it. The other patches in this series use the same helper. Gate ipgre_changelink() and erspan_changelink() with it, at the top of the op before any attribute is parsed, because the parsers update live tunnel fields first. ipgre_netlink_parms() sets t->collect_md before ip_tunnel_changelink() runs.

Networking changes for 7.2.
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

- Support DEVMEM/DMABUF Tx over NETMEM_TX_NO_DMA devices (netkit).

net: skmsg: preserve sg.copy across SG transforms
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: move the protocol out of tree
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: stop storing per-interface state in struct net_device
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: remove dead sockmap (psock) handling from the SW path
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: remove orphaned uAPI for deleted drivers, protocols and SVCs
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...

atm: remove unused ATM PHY operations
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.

atm: remove the unused pre_send and send_bh device operations
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: remove SVC socket support and the signaling daemon interface
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.

atm: remove the local ATM (NSAP) address registry
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.

atm: remove the unused send_oam / push_oam callbacks
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.

xbc_snprint_cmdline() function and its buffer from main.c to the shared
lib/bootconfig.c parser library so it can be reused by userspace tools.
. tools/bootconfig: render kernel.* subtree as cmdline string with -C. Add a
new -C option to print the kernel.* subtree as a flat command-line string
at build time, allowing early parameter injection without runtime parsing.

Both the local (DEFER_TASKRUN) and the normal (tctx) task_work lists 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. * tag 'for-7.2/io_uring-20260615' of git://git.kernel.org/pub/scm/linux/kernel/git/axboe/linux: (31 commits) io_uring/bpf-ops: add a separate maintainer entry io_uring/net: make POLL_FIRST receive side checks consistent io_uring: remove the per-ctx fallback task_work machinery io_uring: run the tctx task_work fallback directly io_uring: switch normal task_work to a mpscq io_uring: switch local task_work to a mpscq io_uring/mpscq: add lockless multi-producer, single-consumer FIFO queue io_uring: grab RCU read lock marking task run io_uring/zcrx: kill dead 'sock' member in struct io_zcrx_args io_uring/kbuf: validate ring provided buffer addresses with access_ok() io_uring/net: support registered buffer for plain send and recv io_uring/nop: Drop a wrong comment in struct io_nop io_uring/net: Remove async_size for OP_LISTEN io_uring/net: Avoid msghdr on op_connect/op_bind async data io_uring/bpf-ops: restrict ctx access to BPF io_uring/io-wq: re-check IO_WQ_BIT_EXIT for each linked work item io_uring/kbuf: align legacy buffer add limit with MAX_BIDS_PER_BGID io_uring/zcrx: add shared-memory notification statistics io_uring/zcrx: notify user on frag copy fallback io_uring/zcrx: notify user when out of buffers ... |

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"

Pull btrfs updates from David Sterba:
"The most noticeable change is to enable large folios by default, it's
been in testing for a few releases. Related to that is huge folio
support (still under experimental config). Otherwise a few ioctl
updates, performance improvements and usual fixes and core changes.
User visible changes:
- enable large folios by default, added in 6.17 (under experimental
build), no feature limitations, a big change internally
- new ioctl to return raw checksums to userspace (a bit tricky given
compression and tail extents), can be used for mkfs and
deduplication optimizations
- provide stable UUID for e.g. overlayfs and temp_fsid, also
reflected in statvfs() field f_fsid, internal dev_t is hashed in to
allow cloning
- add 32bit compat version of GET_SUBVOL_INFO ioctl
- in experimental build, support huge folios (up to 2M)
Performance related improvements/changes:
- limit bio size to the estimated optimum derived from the queue,
this prevents build up of too much data for writeback, which could
cause latency spikes (reported improvement 15% on sequential
writes)
- don't force direct IO to be serialized, forgotten change during
mount API port, brings back +60% of throughput
- lockless calculation of number of shrinkable extent maps, improve
performance with many memcg allocated objects
Notable fixes:
- in zoned mode, fix a deadlock due to zone reclaim and relocation
when space needs to be flushed
- don't trim device which is internally not tracked as writeable
(e.g. when missing device is being rescanned)
- fix deadlock when cloning inline extent and mounted with
flushoncommit
- fix false IO failures after direct IO falls back to buffered write
in some cases
Core:
- remove COW fixup mechanism completely; detect and fix changes to
pages outside of filesystem tracking, guaranteed since 5.8, grace
period is over
- remove 2K block size support, experimental to test subpage code on
x86_64 but now it would block folio changes
- tree-checker improvements of:
- free-space cache and tree items
- root reference and backref items
- extent state exceptions in reloc tree
- subpage mode updates:
- code optimizations, simplify tracking bitmaps
- re-enable readahead of compressed extent
- extend bitmap size to cover huge folios
- add tracepoints related to sync, tree-log and transactions
- device stats item tracking unification, remove item if there are no
stats recorded, also don't leave stale stats on replaced device
- allow extent buffer pages to be allocated as movable, to help page
migration
- added checks for proper extent buffer release
- btrfs.ko code size reduction due to transaction abort call
simplifications
- several struct size reductions
- more auto free conversions
- more verbose assertions"

spi: Updates for v7.2
This has been quite a busy release, mainly due to the subsystem wide
work Johan Hovold has done to modernise resource allocation for the
subsystem on probe, the subsystem did some very clever allocation
management pre devm which didn't quite mesh comfortably with managed
allocations and made it far too easy to introduce error handling and
removal bugs.
- Cleanup and simplification of controller struct allocation, moving
everything over to devm and making the devm APIs more robust, from
Johan Hovold
- Support for spi-mem devices that don't assert chip select and support
for a secondary read command for memory mapped flashes, some commits
for this are shared with mtd.
- Support for SpacemiT K1.
There will be a simple add/add conflict with the i2c-host tree in the
x86 quirk data in drivers/acpi/acpi_apd.c.

wide cleanup of platform devices but nothing in the core.
- Cleanups of platform_device_id usage.
- Filling out and fixing of the description of the MediaTek MT6359
- Removal of the PCAP regulator driver, the MFD has been removed.
- New device support for Qualcomm Nord RPMH, PM8109, PM8150 and

Pull power sequencing updates from Bartosz Golaszewski:
"A set of extensions to the M.2 pwrseq driver allowing it to work with
more cards than just the one from Qualcomm we supported initially.
There's also a tweak to debugfs output and a new function that will be
used by a bluetooth driver in the next cycle.
Power Sequencing core:
- Add a helper allowing consumers to access the struct device object
associated with a pwrseq provider
- Print the power sequencing device's parent in debugfs to add more
debugging information
Driver updates:
- Extend/rework the M.2 power sequencing driver in order to allow it
to support more M.2 cards, not just WCN7850"

chrome-platform: Updates for v7.2
* Improvements
- Use named initializers for struct i2c_device_id.
* Fixes
- Fix a probe race between cros_ec_sensorhub and cros_ec_sysfs.
- Check for the presence of ACPI_COMPANION() for drivers converted
from acpi_driver to platform_driver to avoid issues where
device_match_driver_override() might forcibly match the driver to
the device.
- Fix a possible UAF in cros_ec_chardev.
- Prevent build for big-endian systems as CHROME_PLATFORMS drivers are
only running and testing under little-endian systems.
* Cleanups
- Drop some redundant bits in cros_kbd_led_backlight and Kconfig.

Preparatory work for MPAM counter assignment:
- Simplify the error handling path when creating monitor group event
configuration directories
- Make the MBM event filter configurable only on architectures that
support it and expose this with the respective file modes in the event
config
- Disallow the MBA software controller on systems where MBM counters are
assignable, as it requires continuous bandwidth measurement that
assignable counters do not guarantee
- Replace a compile-time Kconfig option for fixed counter assignment
with a per-architecture runtime property, and expose whether the
counter assignment mode is changeable to userspace
- Continue counter allocation across all domains instead of aborting at
the first failure
- Document that automatic MBM counter assignment is best effort and may
not assign counters to all domains
- Document the behavior of task ID 0 and idle tasks in the resctrl tasks

tcp: rehash onto different local ECMP path on retransmit timeout
Currently sk_rethink_txhash() re-rolls the socket's txhash on RTO, PLB, and spurious-retransmission events, but the cached route is reused and the new hash is not propagated into the ECMP path selection logic. Two changes are needed to make rehash select a different local ECMP path: 1. Add __sk_dst_reset() alongside sk_rethink_txhash() in tcp_write_timeout(), tcp_rcv_spurious_retrans(), and tcp_plb_check_rehash() so the cached dst is invalidated and the next transmit triggers a fresh route lookup. 2. Set fl6->mp_hash from sk_txhash (or tcp_rsk(req)->txhash for SYN/ACK retransmits and syncookies) in tcp_v6_connect(), inet6_sk_rebuild_header(), inet6_csk_route_req(), inet6_csk_route_socket(), tcp_v6_send_response(), and cookie_v6_check() so fib6_select_path() picks a path based on the new hash. The mp_hash override only applies to fib_multipath_hash_policy 0 (the default L3 policy). Its hash includes the flow label, but that is 0 by default -- np->flow_label is unset, and auto_flowlabels only computes the on-wire label later, per packet -- so flows to the same peer share one local path. Keying the hash on sk_txhash makes the local path per-connection and lets a rehash re-select it. Policies 1-3 are left unchanged. The mp_hash assignment is factored into a small helper, ip6_ecmp_set_mp_hash(), shared by inet6_csk_route_req(), inet6_csk_route_socket(), tcp_v6_connect(), inet6_sk_rebuild_header(), tcp_v6_send_response(), and cookie_v6_check(). It applies (txhash >> 1) ?: 1 for policy 0 (the >> 1 keeps mp_hash in the 31-bit range; ?: 1 keeps it non-zero, since 0 would fall back to rt6_multipath_hash()). inet6_csk_route_socket() calls it only for sk_protocol == IPPROTO_TCP so that non-TCP callers (e.g., L2TP via inet6_csk_xmit) fall through to rt6_multipath_hash() and retain their existing flow-key-based ECMP behavior. tcp_v6_send_response() also sets mp_hash from the response txhash so that a control packet (a RST from the full socket, or an ACK from a time-wait socket) selects the same local ECMP nexthop as the connection's txhash rather than falling back to the flow hash. The time-wait socket's tw_txhash is copied from sk_txhash when the connection enters TIME_WAIT, so it reflects any rehash that occurred. Setting mp_hash explicitly is necessary because the default ECMP hash derives from fl6->flowlabel via np->flow_label, which is not updated from sk_txhash (REPFLOW is off by default). ip6_make_flowlabel() cannot help either, as it runs after the route lookup. As a consequence, for policy 0 the local ECMP path of an IPv6 TCP flow follows sk_txhash even when fl6->flowlabel is non-zero, e.g. a reflected (REPFLOW) or explicitly set (IPV6_FLOWLABEL_MGR) flow label. This is intentional: only local path selection changes, so rehash can recover from a failed path; the on-wire flow label is unchanged. sk_set_txhash() is moved before ip6_dst_lookup_flow() in tcp_v6_connect() so the initial ECMP path is selected by the same txhash that subsequent route rebuilds will use. This avoids unintended path changes when the cached dst is naturally invalidated (e.g., by PMTU discovery or route changes). The rehash sites (tcp_write_timeout(), tcp_plb_check_rehash(), and tcp_rcv_spurious_retrans()) call __sk_rethink_txhash_reset_dst(), which re-rolls the txhash and, when it changed, drops the cached dst so the next transmit re-runs route selection. The dst reset is guarded by sk->sk_family == AF_INET6 since IPv4 ECMP does not currently use sk_txhash for path selection. For IPv4-mapped IPv6 sockets this produces a redundant dst reset on a cold path (RTO/PLB); the subsequent IPv4 route lookup returns the same result. The helper is deliberately separate from sk_rethink_txhash() itself: dst_negative_advice() calls sk_rethink_txhash() before its own dst op, so resetting the dst inside sk_rethink_txhash() would skip that op (e.g. rt6_remove_exception_rt()). For syncookies, cookie_init_sequence() computes the cookie value before route_req() and sets txhash so the SYN-ACK selects the same ECMP path that cookie_v6_check() will use when the full socket is created. cookie_tcp_reqsk_init() derives txhash from the cookie so the full socket's ECMP path matches the SYN-ACK. Both the SYN-ACK assignment in tcp_conn_request() and the full-socket assignment in cookie_tcp_reqsk_init() set txhash from the cookie for IPv4 and IPv6 alike. On IPv6 this drives ECMP path selection; on IPv4, which does not use sk_txhash for ECMP, it only affects TX-queue selection. That selection scales the hash by its high bits (reciprocal_scale()), which are uniform in the keyed secure_tcp_syn_cookie() output -- the MSS index only perturbs the low bits -- so the queue distribution matches net_tx_rndhash(). cookie_init_sequence() is split from the former version that also called tcp_synq_overflow() and incremented SYNCOOKIESSENT; those side effects are now in cookie_record_sent(), called after route_req() succeeds so they are not bumped when route_req() fails. cookie_record_sent() is guarded by CONFIG_SYN_COOKIES to match the guard on tcp_synq_overflow(). route_req() receives 0 as tw_isn for the syncookie path so that tcp_v6_init_req() still saves ireq->pktopts for REPFLOW flowlabel reflection and IPv6 cmsg options. The ecn_ok clear for syncookies without timestamps stays after tcp_ecn_create_request() so it takes precedence.

net: dsa: netc: add VLAN filter table and egress treatment management
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.

net: enetc: add helpers to set/clear table bitmap
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).

net: dsa: netc: initialize the group bitmap of ETT and 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.

net: enetc: add "Update" operation to the egress count table
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.

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.

====================
Netfilter/IPVS updates for net-next
The following patchset contains Netfilter/IPVS updates for net-next.
More specifically, this contains conncount rework to address AI related
reports, assorted Netfiter updates and two small incremental updates on
IPVS:
1) Replace old obsolete workqueues (system_wq, system_unbound_wq)
in IPVS, from Marco Crivellari.
2) Replace WARN_ON{_ONCE} by DEBUG_NET_WARN_ON_ONCE in nf_tables.
In the recent years, reporters say that the use of WARN_ON{_ONCE}
in conjunction with panic_on_warn=1 results in DoS. Let's replace
it by DEBUG_NET_WARN_ON_ONCE so this is only exercised by test
infrastructure and fuzzers, while also providing context to AI
agents. From Fernando F. Mancera.
Five patches from Florian Westphal to address AI reports in the conncount
infrastructures:
3) Fix missing rcu read lock section when calling
__ovs_ct_limit_get_zone_limit().
4) Add a dedicate lock per rbtree tree, this increases memory
usage but it should improve scalability.
5) Add a helper function to find the rbtree node, no functional
changes are intented.
6) Add sequence counter to detect concurrent tree modifications
and retry lookups.
7) Add locks to GC conncount walk and address other nitpicks.
Then, several assorted updates:
8) Defensive Tree-wide addition of NULL checks for ct extensions.
9) Bail out if flowtable bypass cannot be fully set up from the
flow offload expression, instead of lazy building a likely
incomplete one.
10) Fix documentation for the new conn_max sysctl toggle in IPVS.
11) Add nf_dev_xmit_recursion*() helpers and use them, to address
recent AI reports.

ipvs: fix doc syntax for conn_max sysctl
netfilter: flowtable: bail out if forward path cannot be discovered

netfilter: nf_conncount: gc and rcu fixes

Locking updates for v7.2:
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.
... with help by André Almeida:
- Add a note about robust list race condition (André Almeida)
- Add self-tests for robust release operations (André Almeida)
Context analysis updates:
- Implement context analysis for 'struct rt_mutex'.
(Bart Van Assche)

- Series to remove NULL check from unconditional guards
(Dmitry Ilvokhin)
Lockdep updates:
- Restore self-test migrate_disable() and sched_rt_mutex
state on PREEMPT_RT (Karl Mehltretter)

- Use per-CPU mutexes for targeted commands (Aniket Gattani)
- Modernize membarrier_global_expedited with cleanup guards

such as mutexes, percpu-rwsems, rtmutexes, rwsems
and semaphores. (Dmitry Ilvokhin)
