Pull rdma updates from Jason Gunthorpe:
"Many AI driven bug fixes, and several big driver API cleanups
- Driver bug fixes and minor cleanups in mlx5, hns, rxe, efa, siw,
rtrs, mana, irdma, mlx4. Commonly error path flows, integer
arithmetic overflows on unsafe data, out of bounds access, and use
after free issues under races.
- Second half of the new udata API for drivers focusing on uAPI
response
- bnxt_re supports more options for QP creation that will allow a dv
path in rdma-core
- Untangle the module dependencies so drivers don't link to
ib_uverbs.ko as was originall intended
- Provide a new way to handle umems with a consistent simplified uAPI
and update several drivers to use it. This brings dmabuf support to
more places and more drivers
- Support for mlx5 rate limit and packet pacing for UD and UC
- A batch of fixes for the new shared FRMR pools infrastructure"

Finish the switch away from __GFP_NO_OBJ_EXT by replacing it with
SLAB_ALLOC_NO_RECURSE when allocating empty sheaves. Pass alloc_flags to
[__]alloc_empty_sheaf(). Callers that can't be part of a recursive
kmalloc() chain simply pass SLAB_ALLOC_DEFAULT. Use kmalloc_flags()
instead of kzalloc() for allocating the sheaf.
With that we can finalize the removal the __GFP_NO_OBJ_EXT handling from
obj_ext allocations as well, leaving only SLAB_ALLOC_NO_RECURSE in
place.
This leaves __GFP_NO_OBJ_EXT with no users in slab, so stop allowing the
flag in kmalloc_nolock().

git://git.kernel.org/pub/scm/linux/kernel/git/tj/sched_ext
Pull sched_ext updates from Tejun Heo:
"Most of this continues the in-development sub-scheduler support, which
lets a root BPF scheduler delegate to nested sub-schedulers. The
dispatch-path building blocks landed in 7.1. A follow-up patchset in
development will complete enqueue-path support for hierarchical
scheduling. This cycle adds most of that infrastructure:
- Topological CPU IDs (cids): a dense, topology-ordered CPU numbering
where the CPUs of a core, LLC, or NUMA node form contiguous ranges,
so a topology unit becomes a (start, length) slice. Raw CPU numbers
are sparse and don't track topological closeness, which makes them
clumsy for sharding work across sub-schedulers and awkward in BPF.
- cmask: bitmaps windowed over a slice of cid space, so a
sub-scheduler can track, for example, the idle cids of its shard
without a full NR_CPUS cpumask.
- A struct_ops variant that cid-form sub-schedulers register with,
along with the cid-form kfuncs they call.
- BPF arena integration, which sub-scheduler support is built on. The
bpf-next additions let the kernel read and write the BPF
scheduler's arena directly, turning it into a real kernel/BPF
shared-memory channel. Shared state like the per-CPU cmask now
lives there.
- scx_qmap is reworked to exercise the new arena and cid interfaces.
Additionally:
- Exit-dump improvements: dump the faulting CPU first, expose the
exit CPU to BPF and userspace, and normalize the dump header.
- Misc kfuncs and cleanups: a task-ID lookup kfunc, __printf checking
on the error and dump formatters, header reorganization, and
assorted fixes"

Pull cgroup updates from Tejun Heo:
- Last cycle deferred css teardown on cgroup removal until the cgroup
depopulated, so a css is not taken offline while tasks can still
reference it. Disabling a controller through cgroup.subtree_control
still had the same problem. This reworks the deferral from per-cgroup
to per-css so that path is covered too.
- New RDMA controller monitoring files: rdma.peak for per-device peak
usage and rdma.events / rdma.events.local for resource-limit
exhaustion. The max-limit parser was rewritten, fixing two input
parsing bugs.
- cpuset: fix a sched-domain leak on the domain-rebuild failure path
and skip a redundant hardwall ancestor scan on v2.
- Misc: pair the remaining lockless cgroup.max.* reads with WRITE_ONCE,
assorted selftest robustness fixes, and doc path corrections.

Support for the Motorola EZX phones based on Intel PXA processors was
removed in 2022, but this driver remained present in the tree. As far
as I can tell, the support was never quite functional upstream because
the board files did not actually instantiate the SPI device for the PCAP.
There are still also drivers for the various mfd cells: keys, touchscreen,
regulator and rtc, all of which are obviously orphaned as well but can
be removed separately as the Kconfig dependency now prevents them from
being enabled.

- Formatting the max77759_chgr_irqs entries to fit in a single line
instead of breaking them into multiple lines to improve readability.
- Refactoring comments such that they're full sentences and have

The old-style gpio handling in wm8994 came from a commit 7c8844481a1c
("mfd: wm8994: Emulate level triggered interrupts if required") in
linux-3.11, but nothing in the kernel ever set the 'irq_gpio' member
in the wm8994_pdata structure, so this was always dead code.
Remove it now to reduce the dependency on the legacy gpio interfaces.

There are board files in-tree that want to request GPIOs from this chip.
They currently rely on the GPIO core's mechanism of matching software
nodes' labels against GPIO controller names. We want to remove this
behavior from the kernel and to this end, we need to associate the
referenced GPIO controller with its target software node.
Create a dedicated GPIO software node for cs5535, assign it to the GPIO
cell and expose its address in a new header.
We only expose a single software node instance but that's alright: all
existing hardware only contains a single cs5535 companion and the geode
board file for which we expose this is legacy anyway.

Some multicolor LEDs support global brightness control in hardware,
meaning that the maximum intensity of the color components is not
connected to the maximum global brightness. Such LEDs cannot be
described properly by the current multicolor LED class interface,
because it assumes that the maximum intensity of each color component
is described by the maximum global brightness of the LED.
Fix this by introducing a new sysfs attribute called
"multi_max_intensity" holding the maximum intensity values for the
color components of a multicolor LED class device. Drivers can use
the new max_intensity field inside struct mc_subled to tell the
multicolor LED class code about those values. Intensity values written
by userspace applications will be limited to this maximum value.
Drivers for multicolor LEDs that do not support global brightness
control in hardware might still want to use the maximum global LED
brightness supplied via devicetree as the maximum intensity of each
individual color component. Such drivers should set max_intensity
to 0 so that the multicolor LED core can act accordingly.
The lp50xx and ncp5623 LED drivers already use hardware-based control
for the global LED brightness. Modify those drivers to correctly
initalize .max_intensity to avoid being limited to the maximum global
brightness supplied via devicetree.

Samsung's S2MU005 PMIC includes subdevices for a charger, an MUIC (Micro
USB Interface Controller), and flash and RGB LED controllers.
S2MU005's interrupt registers divided into three domains, each for the
charger, flash LEDs, and the MUIC, packed into a single regmap IRQ chip
construct.
In devices other than S2MPG1X, the revision can be retrieved from the
first register of the PMIC regmap. In S2MU005 however, the location is
in offset 0x73. Introduce a switch-case block to allow selecting the
REG_ID register. S2MU005 also has a field mask for the revision. Apply
it using FIELD_GET() and get the extracted value.
Add initial support for S2MU005 in the PMIC driver, along with its three
interrupt chips, and support for allowing to fetch revision based on the
device variant.

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.

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

configuration
- support Socket Direct (multi-PF) with switchdev offloads

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

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.

blk_time_get_ns() caches ktime_get_ns() in current->plug->cur_ktime
and marks the task with PF_BLOCK_TS. That cache is only valid while the
task keeps running; if the task is switched out, wall-clock time
advances and the cached value must not be reused when the task runs again.
The existing invalidation covers explicit plug flushes through
__blk_flush_plug(), and the schedule() / rtmutex paths through
sched_update_worker(). It does not cover in-kernel preemption paths such
as preempt_schedule(), preempt_schedule_notrace(), and
preempt_schedule_irq(), which enter __schedule(SM_PREEMPT) directly and
return without calling sched_update_worker().
As a result, a task preempted while holding a plug with PF_BLOCK_TS set
can reuse a stale plug->cur_ktime after it is scheduled back in. blk-iocost
then consumes that stale timestamp through ioc_now(), producing stale vnow
values for throttle decisions, and through ioc_rqos_done(), inflating
on-queue time and feeding false missed-QoS samples into vrate
adjustment.
Move the schedule-side invalidation to finish_task_switch(), which runs
for the scheduled-in task after every actual context switch regardless
of which schedule entry point was used. Keep __blk_flush_plug() as the
explicit flush/finish-plug invalidation path, and remove only the
PF_BLOCK_TS handling from sched_update_worker().

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

pre_send and the raw AAL0/AAL5 paths always fell back to ->send().

atmdev_ops::change_qos() was the hook for renegotiating the traffic
parameters of an already-connected VCC, driven from SO_ATMQOS on a

None of the ATM drivers left in tree implement it - solos-pci only listed
change_qos = NULL - so atm_change_qos() always returned -EOPNOTSUPP.

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 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.

The normal task_work path used a tw_pending bit to ensure the callback
was only added once: the mpscq drains incrementally, so a single
tctx_task_work() run can take the queue through empty -> non-empty
several times, and each transition would otherwise re-add the already
pending callback_head. This corrupts the task_work list, and is what
tw_pending protects again.
This can go away, if we stop running the task_work as soon as the queue
empties.

Heiko Carstens says:
===================
This is supposed to improve s390 idle time accounting, and brings it
back to the state it was before arch_cpu_idle_time() was removed from
s390 [3].
In result all cpu time accounting is done by the s390 architecture backend
again, instead of having a mix of architecure specific and common code
accounting (common code: idle, s390 architecture: everything else).

Pull bootconfig updates from Masami Hiramatsu:
- bootconfig: move xbc_snprint_cmdline() to lib/bootconfig.c
Move the 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.
- 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.

Pull io_uring updates from Jens Axboe:
- Rework the task_work infrastructure.
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.
