ASoC: Fixes for v7.2
We've got a good collection of device specific fix here, plus a couple
of stand out things:
- Richard fixed some special cases with the new device_link creation
by more gracefully handling any errors during creation.
- Charles did some light refactoring of the SoundWire interfaces to
fix some persistent randconfig issues that people kept running into.

With an extra event mask we can easily extend the netdev work
to also service driver-defined events. For advanced drivers
this is probably not a perfect match, but it makes running
deferred work easier in simple cases.
Expose the netdev_work facility to drivers. Add helpers
to schedule work and a dedicated ndo to perform the driver-
-scheduled actions.

The rx_mode update runs from a workqueue: drivers have their
ndo_set_rx_mode_async() callback executed by a single global
work item under RTNL and ops lock. This is a useful pattern.
Support multiple "events" that need to be serviced and make RX_MODE
sync the first one. Call the events "core" because later on
we will let drivers define and schedule their own.

Looks like I missed ethtool_op_get_link() trying to sync linkwatch,
which needs rtnl_lock. Not all drivers do this - bnxt doesn't,
it just returns the link state, so add an opt-in bit.

Pablo Neira Ayuso says:
====================
Netfilter fixes for net
The following patchset contains Netfilter fixes for net:
1) Add a workaround to avoid a possible crash if nf_nat and nft_chain_nat are
compiled built-in and nf_nat fails to register, allowing nft_chain_nat to
access the incorrect pernetns area. This is crash specific of all built-in
compilation. From Matias Krause.
2) Revisit conncount GC optimization for confirmed conntracks, skip GC round
if IPS_ASSURED is set on. This is addressing an issue for corner case
use case scenario involving locally generated traffic. No crash, just a
functionality fix. From Fernando F. Mancera.
3) Validate iph->ihl in flowtable IPIP tunnel support, from Lorenzo Bianconi.
This a sanity check to bounces back malformed IPIP packets to classic
forwarding path.
4) Kdoc fixes for x_tables.h, from Randy Dunlap.
5) Use info->options so nft_synproxy_tcp_options() stays on the same local
snapshot, otherwise eval path can observe inconsistent mix of mss and
timestamps. From Runyu Xiao.
6) Add conntrack_sctp_collision.sh to cover for SCTP INIT collisions.
From Yi Chen.
7) Do not allow NFPROTO_UNSPEC targets if family is NFPROTO_BRIDGE in
nft_compat. This allows to use non-sense targets such as xt_nat leading
to crash. From Florian Westphal.
8) Add a selftest queueing from bridge family. From Florian Westphal.
9) Do not allow to reset a conntrack helper via ctnetlink. This feature
antedates the creation of the conntrack-tools, and it is not used
I don't have a usecase for it, I prefer to remove than fixing it.
10) Add deprecation warning for IPv4 only conntrack helpers for PPTP
and IRC. From Florian Westphal.
11) Store the master tuple in the expectation object and use it,
otherwise SLAB_TYPESAFE_RCU rules allow to display incorrect
master tuple information through ctnetlink.
12) Run expectation eviction when inserting an expectation with no
helper, this is a fix for the nft_ct custom expectation support.
13) Fix nft_ct custom expectation timeouts, userspace provides a
timeout in milliseconds but kernel assumes this comes in seconds.
From Florian Westphal.
14) Cap maximum number of expectations per class to 255 expectations
per master conntrack at helper registration. This is a fix to
restrict the maximum number of expectations per master conntrack
which can be a issue for the new lazy GC expectation approach.

git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci
Pull pci updates from Bjorn Helgaas:
"Enumeration:
- Remove MPS/MRRS Kconfig settings (CONFIG_PCIE_BUS_*) that worked
around a WiFi device defect; use a quirk or boot-time
"pci=pcie_bus_tune_*" kernel parameter instead (Bjorn Helgaas)
- Always lift 2.5GT/s restriction in PCIe failed link retraining to
avoid clamping a link to 2.5GT/s after hot-plug changes the device
(Maciej W. Rozycki)
- Request bus reassignment when not probe-only to fix an enumeration
regression on Marvell CN106XX and possibly other DT-based systems
(Ratheesh Kannoth)
- Fix procfs race between pci_proc_init() and pci_bus_add_device()
that resulted in 'proc_dir_entry ... already registered' warnings
and pointer corruption (Krzysztof Wilczyński)
- Fix sysfs race that causes 'duplicate filename' warnings and boot
panics by converting PCI resource files to static attributes
(Krzysztof Wilczyński)
- Expose sysfs 'resourceN_resize' attributes only on platforms with
PCI mmap (Krzysztof Wilczyński)
- Require CAP_SYS_ADMIN to write to sysfs 'resourceN_resize'
attributes (Krzysztof Wilczyński)
- Add security_locked_down(LOCKDOWN_PCI_ACCESS) to alpha PCI resource
mmap path to match the generic path (Krzysztof Wilczyński)
- Use kstrtobool() to parse the 'rom' attribute input to avoid the
unexpected behavior of enabling the ROM when writing '0' with no
trailing newline (Krzysztof Wilczyński)
Resource management:
- Improve resource claim logging for debuggability (Ilpo Järvinen)
- Clean up several uses of const parameters (Ilpo Järvinen)
- Check option ROM header signatures and lengths before accessing to
avoid page faults and alignment faults (Guixin Liu)
ASPM:
- Don't reconfigure ASPM when entering low-power D-state; only do it
when returning back to D0 (Carlos Bilbao)
Power management:
- During suspend, set power state to 'unknown' for all devices, not
just those with drivers (Lukas Wunner)
- Skip restoring Resizable BARs and VF Resizable BARs if device
doesn't respond to config reads, to avoid invalid array accesses
(Marco Nenciarini)
- Add pci_suspend_retains_context() so drivers can tell whether
devices retain internal state across suspend/resume, since some
platforms reset devices on suspend; use this in nvme to avoid
issues on Qcom RCs (Manivannan Sadhasivam)
Power control:
- Only to power on/off devices that actually support power control to
avoid poking at incompatible devices mentioned in DT (Manivannan
Sadhasivam)
Virtualization and resets:
- Log device readiness timeouts as errors, not warnings, because the
device is likely unusable in this case (Bjorn Helgaas)
- Wait for device readiness after soft reset (D3hot ->
D0uninitialized transition), when the device may respond with
Request Retry Status (RRS) if it needs more time to initialize
(Bjorn Helgaas)
- Drop unnecessary retries when restoring BARs because resets should
now already include all required delays (Lukas Wunner)
- Avoid FLR for MediaTek MT7925 WiFi, where FLR fails after a VM
terminates uncleanly (Jose Ignacio Tornos Martinez)
- Avoid SBR for Qualcomm WCN6855/WCN7850 WiFi, SDX62/SDX65 modems,
which seem not to support it correctly (Jose Ignacio Tornos
Martinez)
Peer-to-peer DMA:
- Prevent P2PDMA as well as CPU access to non-mappable BARs, e.g.,
s390 ISM BARs (Matt Evans)
- Add Intel QAT, DSA, IAA devices to whitelist (Lukas Wunner)
Endpoint framework:
- Add endpoint controller APIs for use by function drivers to
discover auxiliary blocks like DMA engines (Koichiro Den)
- Remember DesignWare eDMA engine base/size and expose them via the
EPC aux-resource API (Koichiro Den)
- Add endpoint embedded doorbell fallback, used if MSI allocation
fails (Koichiro Den)
- Validate BAR index and remove dead BAR read in endpoint doorbell
test (Carlos Bilbao)
- Unwind MSI/MSI-X vectors if NTB initialization fails part-way
through (Koichiro Den)
- Cache sleepable pci_irq_vector() value at ISR setup to avoid
calling it from hardirq context (Koichiro Den)
- Call sleepable pci_epc_raise_irq() from a work item instead of
atomic context, e.g., when setting bits in NTB peer doorbells in
the ntb_peer_db_set() path (Koichiro Den)
- Report 0-based vNTB doorbell vector to account for link event 0 and
historically skipped slot 1 (Koichiro Den)
- Prevent configfs writes to vNTB db_count and other values that are
already in use after EPC attach (Koichiro Den)
- Account for vNTB db_valid reserved slots (link event 0 and
historically skipped slot 1) so they don't appear as valid
doorbells (Koichiro Den)
- Implement vNTB .db_vector_count()/mask() for doorbells so clients
can use multiple vectors and avoid thundering herds (Koichiro Den)
- Report 0-based NTB doorbell vector to account for link event 0 and
historically skipped slot 1 (Koichiro Den)
- Fix doorbell bitmask and IRQ vector handling to clear only
specified bits, use the correct vector for non-contiguous Linux IRQ
numbers, and validate incoming vectors (Koichiro Den)
- Implement NTB .db_vector_count()/mask() for doorbells so clients
can use multiple vectors (Koichiro Den)
Native PCIe controller infrastructure:
- Add pci_host_common_link_train_delay() for the mandatory delay
after > 5GT/s Link training completes and use it for cadence HPA,
j721e, LGA; dwc; aardvark, mediatek-gen3, rzg3s (Hans Zhang)
- Protect root bus removal with rescan lock in altera, brcmstb,
cadence, dwc, iproc, mediatek, plda, rockchip to prevent
use-after-free or crashes when racing with sysfs rescan or hotplug
(Hans Zhang)
- Add pci_host_common_parse_ports() for use by any native driver to
parse Root Port properties (per-Link features like width, speed,
PHY, power and reset control, etc should be described in Root Port
stanzas, not the host bridge; currently only reset GPIOs
implemented) (Sherry Sun)
New native PCIe controller drivers:
- Add DT binding and driver for UltraRISC DP1000 PCIe controller
(Xincheng Zhang, Jia Wang)

by removal of CONFIG_PCIE_BUS_* (see above)
Freescale i.MX6 PCIe controller driver:
- Move IMX6SX_GPR12_PCIE_TEST_POWERDOWN handling into the core reset
functions (Richard Zhu)
- Assert PERST# before enabling regulators to ensure that even if
power is enabled, endpoint stays inactive until REFCLK is stable
(Sherry Sun)
- Parse reset properties in Root Port nodes (falling back to host
bridge) to help support Key E connectors and the pwrctrl framework
(Sherry Sun)
- Configure i.MX95 REF_USE_PAD before PHY reset (Richard Zhu)
- Assert i.MX95 ref_clk_en after reference clock stabilizes (Richard
Zhu)
- Integrate new pwrctrl API for DTs with Root Port-level power
supplies (Sherry Sun)
Intel Gateway PCIe controller driver:
- Enable clock before PHY init for correct ordering (Florian Eckert)
- Add .start_link() callback so the driver works again (Florian
Eckert)
- Stop overwriting the ATU base address discovered by

MediaTek PCIe Gen3 controller driver:
- Deassert PCIE_PHY_RSTB so REFCLK is stable for at least 100ms
(PCIE_T_PVPERL_MS) before deasserting PERST# (Jian Yang)
- Add .shutdown() to assert PERST# before powering down device (Jian
Yang)
- Do full device power down on removal, including asserting PERST#,
when removing driver (Chen-Yu Tsai)
- Fix a 'failed to create pwrctrl devices' error message that was
inadvertently skipped (Chen-Yu Tsai)

since DBI may be inaccessible after PME_Turn_Off (Krishna Chaitanya
Chundru)
- Power down PHY via PARF_PHY_CTRL before disabling rails/clocks to
avoid power leakage (Krishna Chaitanya Chundru)
- Decide whether suspend should put the link in L2 and power down

ASPM L1 is enabled (Krishna Chaitanya Chundru)
- Add qcom D3cold support to tear down interconnect bandwidth and OPP
votes (Krishna Chaitanya Chundru)
- Handle unsupported mixed PERST#/PHY DT configurations, e.g., PHY in

bio_integrity_alloc_buf usage of GFP_ flags is messed up. For one it
mixes GFP_NOFS and GFP_NOIO for neighbouring allocations, but it also
makes the allocations fail more often than needed. That code was copied
from bio_alloc_bioset which needs to do that so that it can punt to the
rescuer workqueue, but none of that is needed for the integrity
allocations that either sits in the file system or at the very bottom
of the I/O stack. Failing early means we'll do a fully waiting
allocation from the mempool ->alloc callback which is usually much
larger than required.
Fix this by passing a gfp_t so that the file system path can pass
GFP_NOFS and the auto-integrity code can pass GFP_NOIO, and don't
modify the allocation type except for disabling warnings.

If device_link_add() fails in snd_soc_bind_card() just skip that
driver pair and carry on.
This means that ASoC must now keep track of which components it was
able to device_link to the card->dev. The new card_device_link member
of struct snd_soc_component is non-NULL if a device_link exists.
The intent of the device link is to ensure that the machine driver
system-suspends before the component drivers, to prevent ASoC
suspend attempting to reconfigure a driver that has already suspended.
It isn't possible to create this device link if the machine driver is
a parent of the component driver or already has a device_link in the
opposite direction. In this case skip the link. A warn is placed in
kernel log since this might indicate a genuine design problem with
those two drivers (this can be downgraded to dbg in future when
people are happy that all these special drivers correctly handle their
reversed shutdown order).

====================
pull request (net): ipsec 2026-06-22
1) xfrm: use compat translator only for u64 alignment mismatch
Gate the XFRM_USER_COMPAT translator on COMPAT_FOR_U64_ALIGNMENT
so 32-bit compat tasks on arches whose 32-bit ABI already matches
the native 64-bit layout are no longer rejected with -EOPNOTSUPP.
From Sanman Pradhan.
2) net: af_key: initialize alg_key_len for IPComp states
Initialize the alg_key_len to 0 in the IPComp branch of
pfkey_msg2xfrm_state() so an uninitialized value cannot drive
xfrm_alg_len() into a slab-out-of-bounds kmemdup during
XFRM_MSG_MIGRATE. From Zijing Yin.
3) xfrm: Fix dev use-after-free in xfrm async resumption
Stash the original skb->dev and extend the RCU critical section
across xfrm_rcv_cb() and transport_finish() to prevent a
tunnel-device UAF and original-device refcount leak when a
callback replaces skb->dev. From Dong Chenchen.
4) xfrm: Fix xfrm state cache insertion race
Move the state-validity check inside xfrm_state_lock in the
input state cache insertion path so a state cannot be killed
between the check and the insert. From Herbert Xu.
5) xfrm: annotate data-races around xfrm_policy_count[] and xfrm_policy_default[]
Add READ_ONCE()/WRITE_ONCE() annotations on xfrm_policy_count
and xfrm_policy_default to silence the KCSAN data race reported
on net->xfrm.policy_count. From Eric Dumazet.
6) espintcp: use sk_msg_free_partial to fix partial send
Replace the manual skmsg accounting in espintcp with
sk_msg_free_partial() so the skmsg stays consistent on every
iteration and the partial-send accounting bugs go away.
From Sabrina Dubroca.
7) xfrm: validate selector family and prefixlen during match
Reject mismatched address families in xfrm_selector_match() and
bound prefixlen in addr4_match()/addr_match() to prevent the
shift-out-of-bounds syzbot reported when an AF_UNSPEC selector
with a large prefixlen is matched against an IPv4 flow.
From Eric Dumazet.

Currently, pci_create_legacy_files() and pci_remove_legacy_files() are
no-op stubs. With legacy attributes now handled by static groups
registered via pcibus_groups[], no call site needs them.
Remove both functions, their declarations, and the call sites in
pci_register_host_bridge(), pci_alloc_child_bus(), and pci_remove_bus().
Remove the pci_sysfs_init() late_initcall and sysfs_initialized. The
late_initcall originally existed to create all the dynamic PCI sysfs files,
but with both resource and legacy attributes now handled by static groups,
it is no longer needed.
Remove the legacy_io and legacy_mem fields from struct pci_bus which were
used to track the dynamically allocated legacy attributes.

On platforms with HAVE_PCI_MMAP or ARCH_GENERIC_PCI_MMAP_RESOURCE, resource
files are now handled by static attribute groups registered via
pci_dev_groups[].
Stub out the pci_create_sysfs_dev_files() and pci_remove_sysfs_dev_files(),
as the dynamic resource file creation is no longer needed.
Also, simplify pci_sysfs_init() on these platforms to only iterate buses
for legacy attributes creation, skipping the per-device loop.
Move the __weak stubs for pci_create_resource_files() and
pci_remove_resource_files() into the #else branch since only platforms
without HAVE_PCI_MMAP (such as Alpha architecture) still need them. Guard
the res_attr[] and res_attr_wc[] fields in struct pci_dev the same way.

Currently, the PCI resource files (resourceN, resourceN_wc) are dynamically
created by pci_create_sysfs_dev_files(), called from both
pci_bus_add_device() and the pci_sysfs_init() late_initcall, with only a
sysfs_initialized flag for synchronisation. This has caused warnings and
boot panics when both paths race on the same device, e.g.:
sysfs: cannot create duplicate filename '/devices/pci0000:3c/0000:3c:01.0/0000:3e:00.2/resource2'
This is especially likely on Devicetree-based platforms, where the PCI host
controllers are platform drivers that probe via the driver model, which can
happen during or after the late_initcall. As such, pci_bus_add_device()
and pci_sysfs_init() are more likely to overlap.
Convert to static const attributes with three attribute groups (I/O, UC,
WC), each with an .is_bin_visible() callback that checks resource flags,
BAR length, and non_mappable_bars. A .bin_size() callback provides
pci_resource_len() to the kernfs node for correct stat and lseek behaviour.
As part of this conversion:
- Rename pci_read_resource_io() and pci_write_resource_io() to
pci_read_resource() and pci_write_resource() since the callbacks are no
longer I/O-specific in the static attribute context.
- Update __resource_resize_store() to use sysfs_create_groups() and
sysfs_remove_groups(), which re-evaluates visibility and runs the
.bin_size() callback for the static resource attribute groups.
- Remove pci_create_resource_files(), pci_remove_resource_files(), and
pci_create_attr() which are no longer needed.
- Move the __weak stubs outside the #if guard so they remain available
for callers converted in subsequent commits.
Platforms that do not define the HAVE_PCI_MMAP macro or the
ARCH_GENERIC_PCI_MMAP_RESOURCE macro, such as Alpha architecture,
continue using their platform-specific resource file creation.
For reference, the dynamic creation dates back to the pre-Git era:
https://git.kernel.org/pub/scm/linux/kernel/git/tglx/history.git/commit/drivers/pci/pci-sysfs.c?id=42298be0eeb5ae98453b3374c36161b05a46c5dc
The write-combine support was added in commit 45aec1ae72fc ("x86: PAT
export resource_wc in pci sysfs").

As SoundWire devices tend to enumerate on the bus after probe, drivers
frequently need to wait for the device to initialise from common driver
code. The common system is to split drivers into a core module and then
a module for each communication bus. These two facts tend to cause
Kconfig issues, the issue tends to be when SOUNDWIRE=m and DRIVER_I2C=y,
this usually selects DRIVER=y. The driver code then wants to call
sdw_slave_wait_for_init(), but this results in calling a module function
from built in code. A depends on SOUNDWIRE | !SOUNDWIRE could be added to
the end driver but this seems slightly off as it adds a lot of counter
intuitive depends.
A simpler solution is to make sdw_slave_wait_for_init() a static inline
function. As part of doing this add a check for the slave device being
NULL acknowledging that this is likely called from code that is shared
between control buses. It does require dropping the call to
sdw_show_ping_status() but this can be added back in end drivers that
used it originally.
Currently this is causing rand config issues on RT5682 and will soon
also cause similar problems on cs42l43.

IRC Direct client-to-client requires plaintext. IRC over TLS should be
preferred, making this helper ineffective. Add a deprecation warning and
update the help text to better reflect that this is needed for the DCC
extension, not IRC itself.
PPTP is esoteric these days and it is the only helper that requires the
destroy callback in the conntrack helper API.
Removal would simplify the conntrack core.
Both helpers are IPv4 only.

Memoryless force-feedback devices use a timer to manage playback of
effects. When a driver for such a device is unbound (or the device is
unregistered for other reasons), the driver typically frees its private
data synchronously. However, the input_dev structure (and its associated
force-feedback structures, including the timer) is only freed when the
last user closes the corresponding device node.
If userspace keeps the device node open while the device is unregistered
(e.g., during driver unbind), the force-feedback timer can still fire
after the driver's private data has been freed.
Introduce a new 'stop' callback to struct ff_device, and call it from
input_unregister_device() before the device is deleted. Implement this
callback for memoryless devices and synchronously shut down the timer to
ensure it is stopped and cannot be rearmed once unregistration happens.

Pull erofs updates from Gao Xiang:
"The most notable change is the removal of the fscache backend: it has
been deprecated for almost two years, mainly because EROFS file-backed
mounts and fanotify pre-content hooks (together with erofs-utils) now
provide better functionality and simpler codebase. In addition,
fscache has depended on netfslib for years, which is undesirable for
EROFS since it is a local filesystem. More details in [1].
In addition, sparse support has been added to the pcluster layout,
which is helpful for large sparse AI datasets, and map requests for
chunk-based inodes have been optimized to be more efficient as well.
There are also the usual fixes and cleanups.
Summary:
- Report more consecutive chunks of the same type for

- Update the EROFS documentation overview

When CONFIG_IP_MULTIPLE_TABLES is enabled but no rule is added,
fib_lookup() performs route lookup directly on two tables.
Since the first lookup does not properly bail out, the result
of an error route in the merged local/main table could be
overwritten by another route in the default table:
# unshare -n
# ip link set lo up
# ip route add 192.168.0.0/24 dev lo table 253
# ip route add unreachable 192.168.0.0/24
# ip route get 192.168.0.1
192.168.0.1 dev lo table default uid 0
cache <local>
Once a random rule is added, the error route is respected:
# ip rule add table 0
# ip rule del table 0
# ip route get 192.168.0.1
RTNETLINK answers: No route to host
Let's fix the inconsistent behaviour.

Add a new function rtc_read_next_alarm() that reads the next expiring
alarm from the RTC timerqueue. This is different from rtc_read_alarm(),
which only reads the aie_timer.
The wakealarm sysfs file programs the rtc->aie_timer, whereas the
alarmtimer suspend routine programs its own timer into the RTC timerqueue.
Both timers end up in the RTC's timerqueue, and the first expiring timer
is what gets armed in the hardware.
This new function allows code to query which alarm will actually fire
next, regardless of which subsystem programmed it. This is needed by
platform code that needs to program secondary timers based on the
actual next wakeup time.

Add the debugfs and trace plumbing used to trigger and observe
manual client reset.
The reset interface exposes a trigger file for operator-initiated
reset and a status file for tracking the most recent run. The
tracepoints record scheduling, completion, and blocked caller
behavior so reset progress can be diagnosed from the client side.
debugfs layout under /sys/kernel/debug/ceph/<client>/reset/:
trigger - write to initiate a manual reset
status - read to see the most recent reset result
The reset directory is cleaned up via debugfs_remove_recursive()
on the parent, so individual file dentries are not stored.
Tracepoints:
ceph_client_reset_schedule - reset queued
ceph_client_reset_complete - reset finished (success or failure)
ceph_client_reset_blocked - caller blocked waiting for reset
ceph_client_reset_unblocked - caller unblocked after reset
All tracepoints use a null-safe access for monc.auth->global_id
to guard against early-init or late-teardown edge cases.

f2fs_recover_orphan_inodes() trusts the orphan block entry_count when
replaying orphan inodes from the checkpoint pack. A corrupted entry_count
larger than F2FS_ORPHANS_PER_BLOCK makes the recovery loop read past the
ino[] array and interpret footer or following data as inode numbers.
On a crafted image, mounting an unpatched kernel can drive orphan recovery
into f2fs_bug_on() and panic the kernel. Validate entry_count before
consuming entries so corrupted checkpoint data fails the mount with
-EFSCORRUPTED and requests fsck instead.
Set ERROR_INCONSISTENT_ORPHAN as well, so the corruption reason can be
recorded in the superblock s_errors[] field. This gives fsck a persistent
hint even though mount-time orphan recovery failure may leave no chance to
persist SBI_NEED_FSCK through a checkpoint.

Pablo Neira Ayuso says:
====================
Netfilter fixes for net
The following patchset contains Netfilter fixes for net. This batches
fixes for real crashes with trivial/correctness fixes. There is too
a rework of the conntrack expectation timeout strategy to deal with
a possible race when removing an expectation.
1) Fix the incorrect flowtable timeout extension for entries in
hw offload, from Adrian Bente. This is correcting a defect in
the functionality, no crash.
2) Hold reference to device under the fake dst in br_netfilter,
from Haoze Xie. This is fixing a possible UaF if the device
is removed while packet is sitting in nfqueue.
3) Reject template conntrack in xt_cluster, otherwise access to
uninitialize conntrack fields are possible leading to WARN_ON
due to unset layer 3 protocol. From Wyatt Feng.
4) Make sure the IPv6 tunnel header is in the linear skb data
area before pulling. While at it remove incomplete NEXTHDR_DEST
support. From Lorenzo Bianconi. This possibly leading to crash
if IPv4 header is not in the linear area.
5) Use test_bit_acquire in ipset hash set to avoid reordering
of subsequent memory access. This is addressing a LLM related
report, no crash has been observed. From Jozsef Kadlecsik.
6) Use test_bit_acquire in ipset bitmap set too, for the same
reason as in the previous patch, from Jozsef Kadlecsik.
7) Call kfree_rcu() after rcu_assign_pointer() to address a
possible UaF if kfree_rcu() runs inmediately, which to my
understanding never happens. Never observed in practise,
reported by LLM. Also from Jozsef Kadlecsik.
8) Use disable_delayed_work_sync() instead cancel_delayed_work_sync()
to avoid that ipset GC handler re-queues work as reported by LLM.
From Jozsef Kadlecsik. This is for correctness.
9) Restore the check in nft_payload for exceeding payloda offset
over 2^16. From Florian Westphal. This fixes a silent truncation,
not a big deal, but better be assertive and reject it.
10) Validate NFT_META_BRI_IIFHWADDR can only run from bridge
prerouting. From Florian Westphal. Harmless but it could allow
to read bytes from skb->cb.
11) Zero out destination hardware address during the flowtable
path setup, also from Florian. This is a correctness fix, LLM
points that possible infoleak can happen but topology to achieve
it is not clear.
12) Skip IPv4 options if present when building the IPV4 reject reply.
Otherwise bytes in the IPv4 options header can be sent back to
origin where the ICMP header is being expected. Again from
Florian Westphal.
13) Replace timer API for expectation by GC worker approach. This
is implicitly fixing a race between nf_ct_remove_expectations()
which might fail to remove the expectation due to timer_del()
returning false because timer has expired and callback is
being run concurrently. This fix is addressing a crash that has
been already reported with a reproducer.
14) Check if br_vlan_get_pvid_rcu() fails, otherwise possible stack
infoleak of 4-bytes. From Florian Westphal.

Pull more slab updates from Vlastimil Babka:
- Introduce and wire up a new alloc_flags parameter for modifying
slab-specific behavior without adding or reusing gfp flags. Also
introduce slab_alloc_context to keep function parameter bloat in
check. Both are similar to what the page allocator does.
kmalloc_flags() exposes alloc_flags for mm-internal users.
- SLAB_ALLOC_NOLOCK flag is used to implement kmalloc_nolock()
behavior without relying on lack of __GFP_RECLAIM, which caused
false positives with workarounds like fd3634312a04 ("debugobject:
Make it work with deferred page initialization - again").
- SLAB_ALLOC_NO_RECURSE replaces __GFP_NO_OBJ_EXT, which could have
been removed, but pending memory allocation profiling changes in
mm tree have grown a new user - there is however a work ongoing
to replace that too, so __GFP_NO_OBJ_EXT should eventually be
removed. (Vlastimil Babka)

kmalloc_flex() in metadata_dst_alloc() sets __counted_by for the
structure to the options_len, which is then initialized to zero.
Later, we're initializing the structure by copying the tunnel info
together with the options, and this triggers a warning for a potential
memcpy overflow, since the compiler estimates that the options can't
fit into the structure, even though the memory for them is actually
allocated.
memcpy: detected buffer overflow: 104 byte write of buffer size 96
WARNING: CPU: X PID: Y at lib/string_helpers.c:1036 __fortify_report
skb_tunnel_info_unclone+0x179/0x190
geneve_xmit+0x7fe/0xe00
The issue is triggered when built with clang and source fortification.
Fix that by doing the copy in two stages: first - the main data with
the options_len, then the options. This way the correct length should
be known at the time of the copy.
It would be better if the options_len never changed after allocation,
but the allocation code is a little separate from the initialization
and it would be awkward and potentially dangerous to return a struct
with options_len set to a non-zero value from the metadata_dst_alloc().
Another option would be to use ip_tunnel_info_opts_set(), but it is
doing too many unnecessary operations for the use case here.

This reverts commit 7b32f64bc512b40b268776c5ac4d354b325b3197.
This patch caused a significant performance regression, so revert it, and
we can determine whether the approach is sensible or not moving forwards,
and if so how to avoid this.
There was a merge conflict with commit de97ae6222c1 ("mm/readahead: no
PG_readahead on EOF"), care was taken to ensure that the revert retained
the behaviour of this patch and cleanly reverts commit 7b32f64bc512 ("mm:
limit filemap_fault readahead to VMA boundaries") only.

After READ_ONLY_THP_FOR_FS is removed, FS either supports large folio or
not. folio_split() can be used on a FS with large folio support without
worrying about getting a THP on a FS without large folio support.
When READ_ONLY_THP_FOR_FS was present, a PMD large pagecache folio can
appear in a FS without large folio support after khugepaged or
madvise(MADV_COLLAPSE) creates it. During truncate_inode_partial_folio(),
such a PMD large pagecache folio is split and if the FS does not support
large folio, it needs to be split to order-0 ones and could not be split
non uniformly to ones with various orders. try_folio_split_to_order() was
added to handle this situation by checking folio_check_splittable(...,
SPLIT_TYPE_NON_UNIFORM) to detect if the large folio is created due to
READ_ONLY_THP_FOR_FS and the FS does not support large folio. Now
READ_ONLY_THP_FOR_FS is removed, all large pagecache folios are created
with FSes supporting large folio, this function is no longer needed and
all large pagecache folios can be split non uniformly.

They are used by READ_ONLY_THP_FOR_FS to handle writes to FSes without
large folio support, so that read-only THPs created in these FSes are not
seen by the FSes when the underlying fd becomes writable. Now read-only
PMD THPs only appear in a FS with large folio support and the supported
orders include PMD_ORDER.
READ_ONLY_THP_FOR_FS was using mapping->nr_thps, inode->i_writecount, and
smp_mb() to prevent writes to a read-only THP and collapsing writable
folios into a THP. In collapse_file(), mapping->nr_thps is increased,
then smp_mb(), and if inode->i_writecount > 0, collapse is stopped, while
do_dentry_open() first increases inode->i_writecount, then a full memory
fence, and if mapping->nr_thps > 0, all read-only THPs are truncated.
Now this mechanism can be removed along with READ_ONLY_THP_FOR_FS code,
since a dirty folio check has been added after try_to_unmap() in
collapse_file() to prevent dirty folios from being collapsed as clean.

Patch series "Remove CONFIG_READ_ONLY_THP_FOR_FS and enable file THP for
writable files", v6.
This patch (of 14):
collapse_file() requires FSes supporting large folio with at least
PMD_ORDER, so replace the READ_ONLY_THP_FOR_FS check with that.
MADV_COLLAPSE ignores shmem huge config, so exclude the check for shmem.
While at it, replace VM_BUG_ON with VM_WARN_ON_ONCE.
Add a helper function mapping_pmd_folio_support() for FSes supporting
large folio with at least PMD_ORDER.

Add three new mTHP statistics to track collapse failures for different
orders when encountering swap PTEs, excessive none PTEs, and shared PTEs:
- collapse_exceed_swap_pte: Increment when mTHP collapse fails due to
encountering a swap PTE.
- collapse_exceed_none_pte: Counts when mTHP collapse fails due to
exceeding the none PTE threshold for the given order
- collapse_exceed_shared_pte: Counts when mTHP collapse fails due to
encountering a shared PTE.
These statistics complement the existing THP_SCAN_EXCEED_* events by
providing per-order granularity for mTHP collapse attempts. The stats are
exposed via sysfs under
`/sys/kernel/mm/transparent_hugepage/hugepages-*/stats/` for each
supported hugepage size.
As we currently do not support collapsing mTHPs that contain a swap or
shared entry, those statistics keep track of how often we are encountering
failed mTHP collapses due to these restrictions.
We will add support for mTHP collapse for anonymous pages next; lets also
track when this happens at the PMD level within the per-mTHP stats.

Letting a function argument indicate whether a lock or unlock operation
should be performed is incompatible with compile-time analysis of locking
operations by sparse and Clang. Hence, split codetag_lock_module_list()
into two functions: a function that locks cttype->mod_lock and another
function that unlocks cttype->mod_lock. No functionality has been
changed. See also commit 916cc5167cc6 ("lib: code tagging framework").

Pages allocated before page_ext is available have their codetag left
uninitialized. Track these early PFNs and clear their codetag in
clear_early_alloc_pfn_tag_refs() to avoid "alloc_tag was not set" warnings
when they are freed later.
Currently a fixed-size array of 8192 entries is used, with a warning if
the limit is exceeded. However, the number of early allocations depends
on the number of CPUs and can be larger than 8192.
Replace the fixed-size array with a dynamically allocated linked list of
pfn_pool structs. Each node is allocated via alloc_page() and mapped to a
pfn_pool containing a next pointer, an atomic slot counter, and a PFN
array that fills the remainder of the page.
The tracking pages themselves are allocated via alloc_page(), which would
trigger __pgalloc_tag_add() -> alloc_tag_add_early_pfn() and recurse
indefinitely. Introduce __GFP_NO_CODETAG (reuses the %__GFP_NO_OBJ_EXT
bit) and pass gfp_flags through pgalloc_tag_add() so that the early path
can skip recording allocations that carry this flag.

Pull firewire updates from Takashi Sakamoto:
- firewire drivers have been able to assign an arbitrary value in the
mod_device entry, which is typed as kernel_ulong_t.
While storing the pointer value is legitimate, conversion back to a
pointer has been performed without preserving the const qualifier.
Uwe Kleine-König introduced an union to provide safer and more robust
conversions, as part of the ongoing CHERI enhancement work for ARM
and RISC-V architectures. This includes changes to the sound
subsystem, since the conversion pattern is widely used in ALSA
firewire stack.
- Userspace applications can request the core function to perform
isochronous resource management procedures. Dingsoul reported a
reference-count leak when these procedures are processed in workqueue
contexts.
This refactors the relevant code paths following a divide and conquer
approach. Consequently, it became clear that the issue still remain
in the path when userspace applications delegate automatic resource
reallocation after bus resets to the core.
In practice, the leak is rarely triggered, and a complete fix is
still in progress.

Not caching negative dentries can result in poor performance for
workloads that repeatedly look up non-existent paths. Each such
lookup triggers a full 9P transaction with the server, adding
unnecessary overhead.
A typical example is source compilation, where multiple cc1 processes
are spawned and repeatedly search for the same missing header files
over and over again.
This change enables caching of negative dentries, so that lookups for
known non-existent paths do not require a full 9P transaction. The
cached negative dentries are retained for a configurable duration
(expressed in milliseconds), as specified by the ndentry_timeout
field in struct v9fs_session_info. If set to -1, negative dentries
are cached indefinitely.
This optimization reduces lookup overhead and improves performance for
workloads involving frequent access to non-existent paths.

This patch replaces the timer API by GC worker approach for
expectations, as it already happened in many other subsystems.
Use the existing conntrack GC worker to iterate over the local list of
expectations in the master conntrack to reap expired expectations.
Check IPS_HELPER_BIT to run GC for expectations, set it on for nft_ct
expectation which nevers sets it. Hold the expectation spinlock while
iterating over the master conntrack expectation list to synchronize with
nf_ct_remove_expectations(). This also performs runtime packet path
garbage collection through the expectation insertion and lookup
functions while walking over one of the chains of the global expectation
hashtables. Unconfirmed conntrack entries are skipped since ct->ext can
be reallocated and dying are skipped since those will be gone soon.
Set on IPS_HELPER_BIT if the helper ct extension is added, then the new
GC worker does not need to bump the ct refcount to check if the ct->ext
helper is available.
This removes the extra bump on the refcount for expectation timers, this
allows to remove several nf_ct_expect_put() calls after the unlink,
after this update only refcount remains at 1 while on the expectation
hashes.
This patch implicitly addresses a race with the existing timer API
allowing an expectation to access a stale exp->master pointer which has
been already released when expectation removal loses races with an
expiring timer, ie. timer_del() reporting false.
Add a new NF_CT_EXPECT_DEAD flag to reap this expectation via GC. This
is needed by nf_conntrack_unexpect_related() which is called in error
paths to invalidate newly created expectations that has been added into
the hashes. These expectactions cannot be inmediately released as GC or
nf_ct_remove_expectations() could race to make it. On expectation
insert, the runtime GC reaps stale expectations before checking the
expectation limit set by policy.
Set current timestamp in nf_ct_expect_alloc(), then add the expectation
policy timeout (or custom timeout specified added on top of this) to
specify the expectation lifetime.

Blamed commit added NFT_META_BRI_IIFHWADDR to the set validate callback,
yet this is a get operation.
Add a get validate callback and move the NFT_META_BRI_IIFHWADDR key
there.
AFAICS this is harmless, NFT_META_BRI_IIFHWADDR can deal with a NULL
input device and the set handler ignores a NFT_META_BRI_IIFHWADDR
operation, but it allows to read 4 bytes off bridge skb->cb[].

Pull MM updates from Andrew Morton:
- "selftests/mm: clean up build output and verbosity" (Li Wang)
Remove some noise from the MM selftests build
- "mm: Free contiguous order-0 pages efficiently" (Ryan Roberts)
Speed up the freeing of a batch of 0-order pages by first scanning
them for coalescing opportunities. This is applicable to vfree() and
to the releasing of frozen pages
- "mm/damon: introduce DAMOS failed region quota charge ratio"
(SeongJae Park)
Address a DAMOS usability issue: The DAMOS quota often exhausts
prematurely because it charges for all memory attempted, causing slow
and inconsistent performance when actions fail on unreclaimable
memory.
To fix this, a new feature lets users set a smaller, flexible quota
charge ratio (via a numerator and denominator) for failed regions.
Since failed actions cause less overhead, reducing their quota cost
ensures more predictable and efficient DAMOS processing

Pull kvm updates from Paolo Bonzini:
"arm64:
This is a bit of an odd merge window on the KVM/arm64 front. There
is absolutely no new feature in the pull request. It is purely
fixes, because it is simply becoming too hard to review new stuff
when so many AI-fuelled fixes hit the list.
- Significant cleanup of the vgic-v5 PPI support which was merged in
7.1. This makes the code more maintainable, and squashes a couple
of bugs in the meantime
- Set of fixes for the handling of the MMU in an NV context,
particularly VNCR-triggered faults. S1POE support is fixed as well
- Large set of pKVM fixes, mostly addressing recurring issues around
hypervisor tracking of donated pages in obscure cases where the
donation could fail and leave things in a bizarre state
- Fixes for the so-called "lazy vgic init", which resulted in
sleeping operations in non-preemptible sections. This turned out to
be far more invasive than initially expected..
- Reduce the overhead of L1/L2 context switch by not touching the FP
registers
- Fix the way non-implemented page sizes are dealt with when a guest
insist on using them for S2 translation
- The usual set of low-impact fixes and cleanups all over the map
Loongarch:
- On a request for lazy FPU load, load all FPU state that the VM
supports instead of enabling only the part (FPU, LSX or LASX) that
caused the FPU load request
- Some enhancements about interrupt injection
- Some bug fixes and other small changes
RISC-V:
- Batch G-stage TLB flushes for GPA range based page table updates
- Convert HGEI line management to fully per-HART
- Fix missing CSR dirty marking when FWFT state updated via ONE_REG
- Fix stale FWFT feature exposure to Guest/VM
- Speed up dirty logging write faults using MMU rwlock and atomic PTE
updates using cmpxchg() for permission-only changes
- Use flexible array for APLIC IRQ state
- Use kvm_slot_dirty_track_enabled() for logging enable check on a
memslot
- Avoid skipping valid pages in kvm_riscv_gstage_wp_range()
- Avoid skipping valid pages in kvm_riscv_gstage_unmap_range()
- Use endian-specific __lelong for NACL shared memory
S390:
- KVM_PRE_FAULT_MEMORY support
- Support for 2G hugepages
- Support for the ASTFLEIE 2 facility
- Support for fast inject using kvm_arch_set_irq_inatomic
- Fix potential leak of uninitialized bytes
- A few more misc gmap fixes
x86:
- Generic support for the more granular permissions allowed by EPT,
namely "read" (which was previously usurping the U bit) and
separate execution bits for kernel and userspace
- Do not assume that all page tables start with U=1/W=1/NX=0 at the
root, as AMD GMET needs to have U=0 at the root
- Introduce common assembly macros for use within Intel and AMD
vendor-specific vmentry code. This touches the SPEC_CTRL handling,
which is now entirely done in assembly for Intel (by reusing the
AMD code that already existed), and register save/restore which
uses some macro magic to compute the offsets in the struct. Both of
these are preparatory changes for upcoming APX support
- Clean up KVM's register tracking and storage, primarily to prepare
for APX support, which expands the maximum number of GPRs from 16
to 32
- Keep a single copy of the PDPTRs rather than two, since
architecturally there is just one
- Handle EXIT_FASTPATH_EXIT_USERSPACE in vendor code to ensure vendor
code gets a chance to handle things like reaping the PML buffer
- Update KVM's view of PV async enabling if and only if the MSR write
fully succeeds
- Fix a variety of issues where the emulator doesn't honor
guest-debug state, and clean up related code along the way
- Synthesize EPT Violation and #NPF "error code" bits when injecting
faults into L1 that didn't originate in hardware (in which case the
VMCS/VMCB doesn't hold relevant information)
- Add support for virtualizing (well, emulating) AMD's flavor of
CPL>0 CPUID faulting
- Clean up the GPR APIs so that KVM's use of "raw" is consistent, and
fix a variety of minor bugs along the way
- Fix an OOB memory access due to not checking the VP ID when
handling a Hyper-V PV TLB flush for L2
- Fix a bug in the mediated PMU's handling of fixed counters that
allowed the guest to bypass the PMU event filter
- Allow userspace to return EAGAIN when handling SNP and TDX
hypercalls, so the KVM can forward a "retry" status code to the
guest, and reserve all unused error codes for future usage
- Overhaul the TDP MMU => S-EPT code to move as much S-EPT specific
logic as possible into the TDX code, and to funnel (almost) all
S-EPT updates into a single chokepoint. The motivation is largely
to prepare for upcoming Dynamic PAMT support, but the cleanups are
nice to have on their own
- Plug a hole in shadow page table handling, where KVM fails to
recursively zap nested EPT/NPT shadow page tables when the nested
hypervisor tears down its own EPT/NPT page tables from the bottom
up
x86 (Intel):
- Support for nested MBEC (Mode-Based Execute Control), see above in
the generic section; also run with MBEC enabled even for non-nested
mode
- Use the kernel's "enum pg_level" in the TDX APIs instead of the
TDX-Module's level definitions (which are 0-based)
- Rework the TDX memory APIs to not require/assume that guest memory
is backed by "struct page" (in prepartion for guest_memfd hugepage
support)
- Fix a largely benign bug where KVM TDX would incorrectly state it
could emulate several x2APIC MSRs
- Use the "safe" WRMSR API when proxying LBR MSR writes as the
to-be-written value is guest controlled and completely unvalidated
x86 (AMD):
- Support for nested GMET (Guest Mode Execution Trap), see above in
the generic section; also run with GMET enabled even for non-nested
mode
- Fixes and minor cleanups to GHCB handling, on top of the earlier
work already merged into 7.1-rc
- Ensure KVM's copy of CR0 and CR3 are up-to-date prior to invoking
fastpath handlers
- Add support for virtualizing gPAT (KVM previously just used L1's
PAT when running L2)
- Fix goofs where KVM mishandles side effects (e.g. single-step and
PMC updates) when emulating VMRUN
- Fix a variety of bugs in AVIC's handling of x2APIC MSR
interception, most notably where KVM didn't disable interception of
IRR, ISR, and TMR regs
- Add support for virtualizing Host-Only/Guest-Only bits in the
mediated PMU
- Don't advertise support for unusable VM types, and account for VM
types that are disabled by firmware, e.g. to mitigate security
vulnerabilities
- Rewrite the SEV {en,de}crypt debug ioctls as they were riddle with
bugs and unnecessarily complicated, and add comprehensive tests
- Clean up and deduplicate the SEV page pinning code
- Fix minor goofs related to writing back CPUID information after
firmware rejects a CPUID page for an SNP vCPU
Generic:
- Rename invalidate_begin() to invalidate_start() throughout KVM to
follow the kernel's nomenclature, e.g. for mmu_notifiers
- Use guard() to cleanup up various KVM+VFIO flows
- Minor cleanups
guest_memfd:
- Return -EEXIST instead of -EINVAL if userspace attempts to bind a
gmem range to multiple memslots, and fix the test that was supposed
to ensure KVM returns -EEXIST
- Treat memslot binding offsets and sizes as unsigned values to fix a
bug where KVM interprets a large "offset + size" as a negative
value and allows a nonsensical offset
- Use the inode number instead of the page offset for the NUMA
interleaving index to fix a bug where the effective index would
jump by two for consecutive pages (the caller also adds in the page
offset)
Selftests:
- Randomize the dirty log test's delay when reaping the bitmap on the
first pass, as always waiting only 1ms hid a KVM RISC-V bug as the
test reaped the bitmap before KVM could build up enough state to
hit the bug
- A pile of one-off fixes and cleanups"

The br_netfilter fake rtable is embedded in struct net_bridge and is
attached to bridged packets with skb_dst_set_noref(). If such a packet is
queued to NFQUEUE, __nf_queue() upgrades that fake dst with
skb_dst_force().
At that point the queued skb can hold a real dst reference after bridge
teardown has started. The problem is not that every bridged packet needs
its own dst reference. The problem is that NFQUEUE can keep the bridge
private fake dst alive after unregister begins.
Fix this by keeping the bridge fake dst model unchanged and pinning the
bridge master device only while the packet sits in NFQUEUE. Record the
bridge device in nf_queue_entry when the queued skb carries a bridge fake
dst, take a device reference for the queue lifetime, and drop it when the
queue entry is freed.
Also make sure queued entries are reaped when that bridge device goes
down, and drop the redundant nf_bridge_info_exists() test from the fake
dst detection.
This keeps netdev_priv(br->dev) alive until verdict completion, so the
embedded fake rtable and its metrics backing storage cannot be freed out
from under dst_release(). It also avoids the constant refcount bump and
avoids using ipv4-specific dst helpers for IPv6 bridge traffic.

Pull ring-buffer updates from Steven Rostedt
- Do not invalidate entire buffer for invalid sub-buffers
For the persistent ring buffer, if one sub-buffer is found to be
invalid, it invalidates the entire per CPU ring buffer. This can lose
a lot of valuable data if there's some corruption with the writes to
the buffer not syncing properly on a hard crash. Instead, if a
sub-buffer is found to be invalid, simply zero it out and mark it for
"missed events".
When the persistent ring buffer is read and a sub-buffer that was
cleared due to being invalid on boot up is discovered, the output
will show "[LOST EVENTS]" to let the user know that events were
missing at that location. Displaying the events from valid buffers
can still be useful.
- Add a test to be able to test corrupted sub-buffers
If a persistent ring buffer is created as "ptraingtest" and the new
config that adds the test is enabled, when a panic happens, the
kernel will randomly corrupt one of the per CPU ring buffers. On boot
up, the sub-buffers with the corruption should be cleared and
flagged. When reading this buffer, the missed events should should
[LOST EVENTS].
- Add commit number in the sub-buffer meta debug info
The commit is used to know the content of a meta page. Add it to the
buffer_meta file that is shown for each per CPU buffer.
- Clean up the persistent ring buffer validation code
Add some helper functions and make variable names more consistent.

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull tracing updates from Steven Rostedt:
- Remove a redundant IS_ERR() check
trace_pipe_open() already checks for IS_ERR() and does it again in
the return path. Remove the return check.
- Export seq_buf_putmem_hex() to allow kunit tests against them
To add Kunit tests on seq_buf_putmem_hex(), it needs to be exported.
- Replace strcat() and strcpy() with seq_buf() logic
The code for synthetic events uses a series of strcat() and strcpy()
which can be error prone. Replace them with seq_buf() logic that does
all the necessary bound checking.
- Add a lockdep rcu_is_watching() to trace_##event##_enabled() call
The trace_##event##_enabled() is a static branch that is true if the
"event" is enabled. But this can hide bugs if this logic is in a
location where RCU is disabled and not "watching". It would only
trigger if lockdep is enabled and the event is enabled.
Add a "rcu_is_watching()" warning if lockdep is enabled in that
helper function to trigger regardless if the event is enabled or not.
- Remove the local variable in the trace_printk() macro
For name space integrity, remove the _______STR variable in the
trace_printk() macro for using the sizeof() macro directly.
- Use guard()s for the trace_recursion_record.c file
- Fix typo in a comment of eventfs_callback() kerneldoc
- Use trace_call__##event() in events within trace_##event##_enabled()
A couple of events are called within an if block guarded by
trace_##event##_enabled(). That is a static key that is only enabled
when the event is enabled. The trace_call_##event() calls the
tracepoint code directly without adding a redundant static key for
that check.
- Allow perf to read synthetic events
Currently, perf does not have the ability to enable a synthetic
event. If it does, it will either cause a kernel warning or error
with "No such device". Synthetic events are not much different than
kprobes and perf can handle fine with a few modifications.
- Replace printk(KERN_WARNING ...) with pr_warn()
- Replace krealloc() on an array with krealloc_array()
- Fix README file path name for synthetic events
- Change tracing_map tracing_map_array to use a flexible array
Instead of allocating a separate pointer to hold the pages field of
tracing_map_array, allocate the pages field as a flexible array when
allocating the structure.
- Fold trace_iterator_increment() into trace_find_next_entry_inc()
The function trace_iterator_increment() was only used by
trace_find_next_entry_inc(). It's not big enough to be a helper
function for one user. Fold it into its caller.
- Make field_var_str field a flexible array of hist_elt_data
Instead of allocating a separate pointer for the field_var_str array
of the hist_elt_data structure, allocate it as a flexible array when
allocating the structure.
- Disable KCOV for trace_irqsoff.c
Like trace_preemptirq.c, trace_irqsoff.c has code that will crash
when KCOV is enabled on ARM. The irqsoff tracing can be called on ARM
because the irqsoff tracing code can be run from early interrupt code
and produce coverage unrelated to syscall inputs.
- Fix warning in __unregister_ftrace_function() called by perf
Perf calls unregister_ftrace_function() without checking if its
ftrace_ops has already been unregistered. There's an error path where
on clean up it will unregister the ftrace_ops even if it wasn't
registered and causes a warning.

strncpy() has been a persistent source of bugs due to its ambiguous
intended usage and frequently counter-intuitive semantics: it may not
NUL-terminate the destination, and it unconditionally zero-pads to the
full length, which isn't always needed. All former callers have been
migrated[1] to:
- strscpy() for NUL-terminated destinations
- strscpy_pad() for NUL-terminated destinations needing zero-padding
- strtomem_pad() for non-NUL-terminated fixed-width fields
- memcpy_and_pad() for bounded copies with explicit padding
- memcpy() for known-length copies
Remove the generic implementation, its declaration, the FORTIFY_SOURCE
wrapper, and associated tests.

Pull nfsd updates from Chuck Lever:
"Jeff Layton wired up netlink upcalls for the auth.unix.ip and
auth.unix.gid caches in SunRPC and the svc_export and nfsd.fh caches
in NFSD. The new kernel-user API is more extensible and lays the
groundwork for retiring the old pipe interface.
The default NFS r/w block size rises to 4MB on hosts with at least
16GB of RAM, reducing per-RPC overhead on fast networks. Smaller
machines keep their previously computed default, and the value remains
tunable through /proc/fs/nfsd/max_block_size.
Chuck Lever converted the server's RPCSEC GSS Kerberos code to the
kernel's shared crypto/krb5 library. The conversion retires and
removes SunRPC's bespoke implementation of Kerberos v5, but keeps
RPCSEC GSS-API.
Continuing the xdrgen migration that converted the NLMv4 server XDR
layer in v7.1, Chuck Lever converted the NLM version 3 server-side XDR
layer from hand-written C to xdrgen-generated code. As with the NLMv4
conversion in v7.1, the goals are improved memory safety, lower
maintenance burden, and groundwork for generation of Rust code for
this layer instead of C.
Chuck Lever fixed an issue where lingering NFSv4 state pins a mounted
file system after it is unexported. A new netlink-based mechanism can
now release NLM locks and NFSv4 state by client address, by
filesystem, and by export. Now an administrator can quiesce an export
cleanly before unmounting it.
The remaining patches are bug fixes, clean-ups, and minor
optimizations, including a batch of memory-leak and use-after-free
fixes in the ACL, lockd, and TLS handshake paths, many of them
reported by Chris Mason. Sincere thanks to all contributors,
reviewers, testers, and bug reporters who participated in the v7.2
NFSD development cycle"

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().

erofs supports large folios for reads, but the actual folio order
instantiated in the page cache may be lower due to allocation
constraints such as memory fragmentation.
trace_erofs_read_folio already receives the folio being read but
currently records only its index. Add folio_order() to the tracepoint
so that users can observe the realized folio order and verify the
effectiveness of large folio reads.
Also drop the uptodate field: read_folio() is only called for a
non-uptodate folio, so it is always 0.

SCTP_DIAG endpoint dumping was traversing endpoint address lists without
holding lock_sock(), while those lists could change concurrently via
socket operations (e.g., bindx changes). This creates a race where
nla_reserve() counts addresses under RCU protection, but the subsequent
copy may see fewer entries, potentially leaking uninitialized memory to
userspace.
Fix this by:
- Taking a reference on each endpoint during hash traversal
- Moving socket operations (lock_sock()) outside read_lock_bh()
- Serializing address list access during dump
- Reworking sctp_for_each_endpoint() to support restart-based traversal
with (net, pos) tracking
Also:
- Add WARN_ON_ONCE() for inconsistent address counts
- Fix idiag_states filtering for LISTEN vs association cases
- Skip dumping endpoints being freed (ep->base.dead)
- Move dump position tracking into iterator, removing cb->args[4] and
its comment for sctp_ep_dump().,
- Update the comment for cb->args[4] and remove the comment for unused
cb->args[5] for sctp_sock_dump().
Note: traversal is restart-based and may re-scan buckets multiple times,
but this is acceptable due to small bucket sizes and required to support
sleeping-safe callbacks.

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.
Commit 8b484efd5cb4 ("ip6: vti: Use ip6_tnl.net in
vti6_siocdevprivate().") added the same check on the ioctl path. This
adds it on RTM_NEWLINK.

Pull SoC devicetree updates from Arnd Bergmann:
"There are fewer devicetree updates this time that the last few ones,
with five SoC types getting added:
- Qualcomm Dragonwing IPQ9650 is a new wireless networking SoC using
four Cortex-A55 and one Cortex-A78 core, which is a significant
upgrade from older generations
- ZTE zx297520v3 is an older low-end wireless SoC using a single
Cortex-A53 core, which so far can only run 32-bit kernels. This
brings back the ZX family of chips that was removed in 2021 after
support for the original zx296702 and zx296718 chips was never
completed.
- Renesas R-Car M3Le (R8A779MD) is a variant of the R-Car M3-N
(R8A77965) automotive SoC.
- Apple t8122 (M3) is the 2023 generation of their laptop SoCs, which
has now been reverse-engineered to the point of having initial
kernel support for five laptop models.
- ASPEED AST27xx is their first baseboard managment controller using
a 64-bit core, the Cortex-A35, following earlier generations using
ARMv5/v6/v7 CPUs.
These all come with one or more initial boards, and in total there are
39 new boards getting added across SoC families, including:
- Two NAS boxes using the old Cortina Systems Gemini SoC based on an
ARMv4 FA526 CPU core
- 18 industrial embedded boards using NXP i.MX6/8/9 and LX2160A SoCs
from Variscite, Toradex and SolidRun, plus a number of overlays for
combinations with additional boards
- One new carrier board and SoM using TI K3 AM62x, in addition to new
overlays for older SoMs
- Two new boards using Spacemit K3 (no relation with TI) RISC-V SoCs.
- Three phones from Google, Nothing and Motorola, all using Qualcomm
Snapdragon SoCs
- AST26xx BMC support for two server boards
While there is still a significant number of patches improving
hardware support for the existing boards across vendors (NXP,
Qualcomm, Renesas, Rockchips, Mediatek, ...), a much smaller number
of cleanups and warning fixes have made it in this time"

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"

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.

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.

syzbot reported a shift-out-of-bounds in xfrm_selector_match()
due to AF_UNSPEC selector with large prefixlen (e.g. 128) matched
against IPv4 flow (when XFRM_STATE_AF_UNSPEC is set).
Fix this by:
- Rejecting mismatched families in xfrm_selector_match.
- Returning false in addr4_match if prefixlen > 32.
- Returning false in addr_match if prefixlen > 128 (prevents overflow).
Fixes: 3f0ab59e6537 ("xfrm: validate new SA's prefixlen using SA family when sel.family is unset")

Pull bpf updates from Alexei Starovoitov:
"Major changes:
- Recover from BPF arena page faults using a scratch page and add
ptep_try_set() for lockless empty-slot installs on x86 and arm64.
This allows BPF kfuncs to access arena pointers directly.
The 'arena_direct_access' stable branch was created for this work
and was pulled into sched-ext and bpf-next trees (Tejun Heo, Kumar
Kartikeya Dwivedi)
- Lift old restriction and support 6+ arguments in BPF programs and
kfuncs on x86 and arm64 (Yonghong Song, Puranjay Mohan)
Other features and fixes:
- Add 24-bit BTF vlen and reclaim unused bits in the BTF UAPI to ease
addition of new BTF kinds (Alan Maguire)
- Raise the maximum BPF call chain depth from 8 to 16 frames (Alexei
Starovoitov)
- Refactor object relationship tracking in the verifier and fix a
dynptr use-after-free bug (Amery Hung)
- Harden the signed program loader and reject exclusive maps as inner
maps (Daniel Borkmann)
- Replace the verifier min/max bounds fields with a circular number
(cnum) representation and improve 32->64 bit range refinements
(Eduard Zingerman)
- Introduce the arena library and runtime (libarena) with a buddy
allocator, rbtree and SPMC queue data structures, ASAN support and
a parallel test harness. Allow subprograms to return arena pointers
and switch to a BTF type-tag based __arena annotation (Emil
Tsalapatis)
- Cache build IDs in the sleepable stackmap path and avoid faultable
build ID reads under mm locks (Ihor Solodrai)
- Introduce the tracing_multi link to attach a single BPF program to
many kernel functions at once. Allow specifying the uprobe_multi
target via FD (Jiri Olsa)
- Extend the bpf_list family of kfuncs with bpf_list_add/del(), and
bpf_list_is_first/is_last/empty() (Kaitao Cheng)
- Extend the BPF syscall with common attributes support for
prog_load, btf_load and map_create (Leon Hwang)
- Wrap rhashtable as BPF map (Mykyta Yatsenko, Herbert Xu)
- Add sleepable support for tracepoint programs and fix deadlocks in
LRU map due to NMI reentry (Mykyta Yatsenko)
- Fix OOB access in bpf_flow_keys, fix nullness analysis of inner
arrays, enforce write checks for global subprograms (Nuoqi Gui)
- Report the maximum combined stack depth and print a breakdown of
instructions processed per subprogram (Paul Chaignon)
- Add an XDP load-balancer benchmark and arm64 JIT support for stack
arguments (Puranjay Mohan)
- Add kfuncs to traverse over wakeup_sources (Samuel Wu)
- Allow sleepable BPF programs to use LPM trie maps directly (Vlad
Poenaru)

git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
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

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.

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...

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

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.

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.

===================
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 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

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"

"This has been quite a busy release, mainly due to the subsystem wide

removal bugs.

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.

When recovering hugepages in the shadow MMU, verify that the base gfn of
the shadow page is actually contained within the target memslot, *before*
querying the max mapping level given the shadow page's gfn. Failure to
pre-check the validity of the gfn can lead to an out-of-bounds access to
the slot's lpage_info (which typically manifests as a host #PF because the
lpage_info is vmalloc'd) if the guest creates a hugepage mapping (in its
PTEs) that extends "below" the bounds of a memslot.
When faulting in memory for a guest, and the size of the guest mapping is
greater than KVM's (current) max mapping, then KVM will create a "direct"
shadow page (direct in that there are no gPTEs to shadow, and so the target
gfn is a direct calculation given the base gfn of the shadow page). The
hugepage recovery flow looks for such direct shadow pages, as forcing 4KiB
mappings when dirty logging generates the guest > host mapping size case.
When the 4KiB restriction is lifted, then KVM can replace the shadow page
with a hugepage.
But if KVM originally used a smaller mapping than the guest because the
range of memory covered by the guest hugepage exceeds the bounds of a
memslot, then KVM will link a direct shadow page with a gfn that is outside
the bounds of the memslot being used to fault in memory. The rmap entry

Don't bother pre-checking the bounds of the potential hugepage, i.e. don't
check that e.g. sp->gfn + KVM_PAGES_PER_HPAGE(sp->role.level + 1) is also
within the memslot, as the checks performed by kvm_mmu_max_mapping_level()
are a superset of the basic bounds checks. I.e. pre-checking the full

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.

Add two interfaces to manage entries in the VLAN filter table:
ntmp_vft_update_entry(): Update the configuration element data of the
specified VLAN filter entry based on the given VLAN ID. It uses the
exact key access method to locate the entry.
ntmp_vft_delete_entry(): Delete the VLAN filter entry corresponding to
the specified VLAN ID. It also uses the exact key access method to
identify the target entry.
In addition, introduce struct vft_req_qd to describe the request data
buffer format for Query and Delete actions of the VLAN filter table,
which contains a common request data header and a VLAN access key.

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.

Pablo Neira Ayuso says:
====================
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.
* tag 'nf-next-26-06-14' of git://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf-next:
netfilter: nf_dup_netdev: add nf_dev_xmit_recursion*() helpers and use them
ipvs: fix doc syntax for conn_max sysctl
netfilter: flowtable: bail out if forward path cannot be discovered

ASoC: Updates for v7.2
There's been quite a lot of framework improvements this time around,
though mainly cleanups and robustness rather than user visible features.
The same pattern is seen with a lot of the driver work that's going on,
there are new features but a huge proportion of this is bug fixing and
cleanup work. We also have a good selectio of new device support.
- Improvements to SDCA jack handling from Charles Keepax.
- Use of device links to make suspend handling more robust from Richard
Fitzgerald.
- Use of a new helper to factor out a common pattern in SoundWire
enmeration from Charles Keepax.
- Slimming down of the component from Kuninori Morimoto.
- Simplification of format auto selection from Kuninori Morimoto.
- Lots of conversions to guard() from Bui Duc Phuc.
- Addition of a simple-amplifier driver supporting more featureful GPIO
controller amplifiers than the previous basic driver from Herve
Codina.
- Support for AMD ACP 7.x, Cirrus Logic CS42448/CS42888, Everest Semi
ES9356, Mediatek MT2701 and MT8196, Renesas RZ/G3E, Spacemit K3,
Texas Instruments TAC5xx2 and TAS67524.
