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

Pull 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.

The cited commit moved fib4_rules_exit() earlier to ->exit_rtnl(),
but the kernel socket destroyed in ->exit() could eventually reach
__fib_lookup().
I left fib4_rules_exit() in ->exit_rtnl() because fib4_rule_delete()
calls fib_unmerge(), which requires RTNL.
However, when ->delete() is called, ->configure() has already been
called, thus fib_unmerge() in ->delete() has no effect.
Let's remove fib_unmerge() in fib4_rule_delete() and move
fib4_rules_exit() to ->exit().
Many thanks to Ido Schimmel for providing the nice repro very quickly.
Note that we can make fib_rules_ops.delete() return void once
net-next opens.

net: serialize netif_running() check in enqueue_to_backlog()
Syzbot reported a KASAN slab-use-after-free in fib_rules_lookup().
The root cause is a race condition where packets can escape the backlog
flushing during device unregistration (e.g., during netns exit).
Commit e9e4dd3267d0 ("net: do not process device backlog during unregistration")
introduced a lockless netif_running() check in enqueue_to_backlog() to
prevent queuing packets to an unregistering device.
However, this creates a TOCTOU race window.
A lockless transmitter (like veth_xmit) can pass
the check before dev_close() clears IFF_UP. If the transmitter is then
delayed, flush_all_backlogs() can run and finish before the transmitter
grabs the backlog lock and queues the packet. The packet then escapes
the flush and triggers UAF later when processed.
Fix this by moving the netif_running() check inside the backlog lock.
This serializes the check with the flush work (which also grabs the lock).
We then either queue the packet before the flush runs (so it gets flushed),
or check netif_running() after the flush/close completes (so it gets dropped).

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

appletalk: stop storing per-interface state in struct net_device
AppleTalk keeps its per-interface control block (struct atalk_iface)
directly in struct netdevice (dev->atalk_ptr). This is the only thing
tying the protocol into the core net_device layout and is the sole
blocker to moving AppleTalk out of tree.
Replace dev->atalk_ptr with a small ifindex-keyed hashtable internal
to ddp.c. The existing atalk_interfaces list stays the owner of the iface
objects; the hashtable is purely a fast dev->iface index and reuses
the same atalk_interfaces_lock.

is, I'm sure Sashiko will point out some basically existing bugs.

We need to reject the attempts to configure the TLS keys (rather
than adding the ULP itself) because checking prior to the ULP
installation is tricky without risking a race with sockmap getting
added in parallel (sockmap does not hold the socket lock).

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

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

atm: remove dead SONET PHY ioctls
The SONET_* ioctls are SONET/SDH PHY controls that atm_dev_ioctl() and
the compat path only ever forwarded to the driver's ->ioctl() handler.
The PHY drivers that implemented them (the S/UNI library and the framers
on the removed PCI/SBUS adapters) are gone, and neither surviving driver
services them: solos-pci has no ->ioctl, and usbatm handles only
ATM_QUERYLOOP. They now uniformly return an error regardless.
Drop the SONET compat passthrough and the SONET cases in atm_dev_ioctl(),
along with the now-unused linux/sonet.h includes. The SONET_* uAPI
definitions are untouched.

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

AAL3/4 is an obsolete connection-oriented ATM adaptation layer that has

and PPPoATM runs over AAL5.

qos.aal == ATM_AAL34 now fails with -EPROTOTYPE.

"--dump-task" instead of the documented "--dump-tasks". Change the
option to match both documentation and the other timerlat tool,
rtla-timerlat-top.
- Extend coverage of runtime tests

- Stop record trace on interrupt
Fix a bug where an interval exists after receiving a signal in which
the main instance is stopped but the record instance is not, leading
to discrepancies in reported results and sometimes rtla hanging.
- Restore continue flag in actions_perform()
Fix a bug where rtla always continues tracing after hitting a
threshold even if the continue action was triggered just once, and
add tests verifying that the flag is reset properly.
- Migrate command line interface to libsubcmd
Replace rtla's argument parsing using getopt_long() with libsubcmd,
used by perf and objtool, to reuse existing code and auto-generate
better help messages. Extensive unit tests are included to detect
regressions.
- Add -A/--aligned option to timerlat tools
Add an option to align timerlat threads, based on the recently
introduced TIMERLAT_ALIGN option of the timerlat tracer, together
with unit tests and documentation.

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.

Reported by syzbot. The root cause is that user-supplied segment

nilfs_fill_super() takes another reference to the same

"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
- 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"

ionic: Expose more port stats to ethtool [part]
The primary aim of this patchset is to support the reporting of new port
statistics (and one old one) that firmware sends to the driver. A scheme
for these extra stats is introduced in order to prevent devices that
don't support these new statistics from unconditionally setting them or
reporting them in ethtool.
====================
Eric Joyner [Sun, 14 Jun 2026 20:53:02 +0000 (13:53 -0700)]
ionic: Get "link_down_count" ext link stat from firmware
The number of times that link has gone down at the port level is tracked
by the firmware and sent to the driver via regular DMA writes to an
instance of struct ionic_port_status in the driver's memory.
This statistic was never reported in favor of a driver-derived stat, but
doing it in the driver was never necessary since firmware had been
reporting it the whole time. Since it would be more accurate and true to
the description of the statistic to get this count at the PHY level,
replace the driver-calculated statistic with one derived from the
firmware one and remove the driver-calculated one entirely.
The stat reported by the ethtool .get_link_ext_stats() handler is
normalized to 0 on driver load and any device resets that require the
driver to rebuild state while also handling overflows.
Eric Joyner [Sun, 14 Jun 2026 20:53:01 +0000 (13:53 -0700)]
ionic: Report "rx_bits_phy" stat to ethtool
This stat contains the number of total bits that the PHY has received;
it's useful for BER calculations. Add it to the ethtool stats output.
However, since this is one of the new "extra port stats", it's reported
in a different manner than the existing port stats and only
conditionally added to the ethtool stats output list: both the
DEV_CAP_EXTRA_STATS capability must be supported by the firmware, and
the firmware must set the value of the statistic to something other than
IONIC_STAT_INVALID.
To help support this scheme, the extra port stats region is initialized to
0xff's/IONIC_STAT_INVALID by the driver, to ensure the statistics that
the driver knows about but the firmware does not are still invalid
to the driver.
Eric Joyner [Sun, 14 Jun 2026 20:53:00 +0000 (13:53 -0700)]
ionic: Update ionic_if.h with new extra port stats
Add a new structure to report additional statistics from the firmware to
struct ionic_port_info. This new struct currently only contains FEC
related statistics, but any new port-level statistics collected by the
firmware would go into it.
The new structure is located in the same area as the unused
ionic_port_pb_stats structure, so this patch also removes that and its
supporting enumerations since they was never used in this driver.
Finally, to indicate firmware support for the new structure, introduce a
new device capability that the driver can use to see if the attached
device supports reporting these extra stats.
Brett Creeley [Sun, 14 Jun 2026 20:52:59 +0000 (13:52 -0700)]
ionic: Fix check in ionic_get_link_ext_stats
The current check will fail if SR-IOV is not initialized for the
physical function; this is because is_physfn is 0 if sriov_init() isn't
run or fails. Change the check that prevents getting the link down count
to use is_virtfn instead so that VFs don't get this functionality, which
was the original intent.

Pull x86 TDX updates from Dave Hansen:
"There are a few cleanups, and some changes that should allow TDX and
kexec to coexist nicely.
The biggest change, however, is support for updating the TDX module
after boot, just like CPU microcode. TDX users really want this
because it lets them do security updates without tearing things down
and rebooting.
- Add TDX module update support
- Make kexec and TDX finally place nice together
- Put TDX error codes into a single header"

Pull x86 mm updates from Dave Hansen:
"There's a small comment fixup, followed by an actual bug fix. The bug
fix is slightly new territory for us. It fixes a real regression, but
it is from ~6.18 not a _new_ regression. It was mostly only biting
folks doing hotplug memory testing. So, it was queued in here and held
for the merge window instead of going via x86/urgent.
- Fix freeing of PMD-sized vmemmap pages
