Pull networking fixes from Jakub Kicinski:
"Including fixes from netfilter.
Looks like our attempt to keep the PRs smaller have only prevented
this one from getting even bigger. In the last 9 days there were
405 postings explicitly tagged with [PATCH net], vs 687 with [PATCH
net-next]. 37% of posted patches being fixes is pretty crazy, and
that's likely undercounting because LLM "researchers" more often post
fixes without knowing to tag the patches for specific trees. I don't
have historic data.
In any case, we keep adjusting the criteria. The next PR will be
smaller.
Current release - regressions:
- net: defer netdev KOBJ_ADD uevent until the device is published,
previously rtnl_lock would serialize the accesses vs publishing
- net: explicitly cancel work to avoid races with ref tracker exit
- qrtr: ns: raise lookup limit to 128
- eth: hns3: fix speed configuration residue after driver reload
Previous releases - regressions:
- tcp: do not change rcv_ssthresh in tcp_measure_rcv_mss(), regressed
flows with MSS and scaling_ratio variability
- Revert "net: thunderbolt: Enable end-to-end flow control also in
transmit", broke some platforms (no packets coming thru)
- eth: stmmac: resume PHY before hardware setup when opening the

Antonio Quartulli says:
====================
Included fixes:
* use rcu_dereference_bh() instead of rcu_access_pointer() where the
pointer is actually dereferenced
* ensure TCP global variables are initialized before they can be
accessed via netlink (e.g. when attaching a TCP socket)
* actually disable IPv4 redirects on multipeer interfaces (the
previous attempt was a no-op and did not survive netns moves)
* hash a floated peer by its transport identity only, consistently
with the add and lookup paths
* zero the sockaddr padding before learning a floated endpoint so it
does not leak into the by_transp_addr hash key
* ensure the socket is owned by ovpn before dereferencing
sk_user_data
* rehash a peer in the by_transp_addr table when its remote endpoint
is updated via CMD_PEER_SET
* avoid re-adding to the hashtables a peer that was concurrently
removed (use-after-free)
* limit keepalive values to one day to avoid overflowing the
delayed-work delay on 32-bit systems
* add the missing rtnl_link_ops->get_size callback so link messages
account for the nested mode attribute
* tag 'ovpn-net-20260730' of https://github.com/OpenVPN/ovpn-net-next:
ovpn: fix incorrect use of rcu_access_pointer()

The security team is still seeing a lot of reports lacking a full patch
and showing missing contents and formatting issues. Since AI assistants
tend to be better than humans at following instructions, let's defer to
coding-assistants.rst to follow mandatory steps, and insist on the plain
text format, as well as asking for recipient addresses and an e-mail
client setup hint to be mentioned early in the report for the reporter.
Also add a link to https://github.com/masoncl/kres.git which contains
way more advanced and detailed steps for those willing to go further.
Tested with Opus-5 and Qwen3.6-27B-Architect-Polaris2-Fable-B-F451, both
of which proceeded according to instructions.

Due to the increasing capabilities of available AI models, it's becoming
common to see them used to find bugs anywhere. Unfortunately the quality
of reports (especially when they're believed to be security relevant) is
still lacking a lot.
Let's add a section dedicated to bug finding, explaining the few
mandatory steps (noting commit ID, writing the fix from the session that
found the bug, building and testing, etc). This was tested both against
Qwen3.6-27B-Architect-Polaris2-Fable-B-F451 running under Hermes, and
Opus-5, and both followed the instructions to the letter, verifying
their results and checking threat-model.rst to decline the vulnerability
aspect. At least in the current form it's expected to improve the
situation a little bit.

Too often we're getting reports saying "still valid in latest mainline"
with no indication of when this was verified, making this indication
pointless. Let's clarify it and insist on having a version or commit ID,
and that the version must necessarily be for a kernel.org kernel and not
a distro one.

When originally writing the "fake USB device" entry, it was difficult
to find a suitable section for it and it ended up in "non production
use" but that doesn't fit particularly well. Actually it's very similar
to crafted filesystems, it's a matter of spec violation. Both drivers
and FS are written against a spec, and what the threat model doesn't
cover is out-of-spec use. So let's move the entry there and rename the
crafted FS entry to "Non-conforming devices and media" instead.
Overall it looks more consistent.
The spec was tested agains Qwen3.6-27B-Architect-Polaris2-Fable-B-F451,
Opus-5 and Gemini by reading the threat-model file, then reading a tens
of FS and driver fixes, and they were now all properly classified as
regular bugs, except two that Gemini and Opus rightfully classified as
vulns (Qwen didn't spot the security potential but that's out of our
scope).

Throwing an LLM (Opus 5) at a file looking for random bugs after having
read the threat model made it ignore certain bugs it found because "the
threat model said they must be ignored". When asked why, the LLM
rightfully reported the ambiguous wording used at a few places:
"is not a security bug", which can also be read as "is not a bug",
despite the rest of the document. That is particularly true when the
LLM decides to look for info using grep.
This change replaces "security bug" with "vulnerability" at a few places
in order to remove this identified ambiguity, and uses "bugs" instead of
issues in two such sentences to insist that what is described remains a
bug.

Pull cgroup fixes from Tejun Heo:
- A pressure trigger's poll timer could be re-armed while the last
trigger was being torn down and then fire after the cgroup was freed.
Tie the timer to the cgroup's lifetime and shut it down when the
cgroup is freed.
- Writing to a pressure file forked a worker kthread while holding the
cgroup mutex, creating lock dependencies from the mutex to the whole
fork path. A pressure write racing a sched_ext scheduler enable,
which blocks forks before grabbing the mutex, deadlocked.
Fork the worker with the mutex dropped.

Certain third-party USB game controllers exposing (or spoofing) an Xbox
360-compatible interface (VID:PID 045e:028e) fail to enumerate under Linux.
The device disconnects from the bus without responding to the initial
GET_DESCRIPTOR(CONFIGURATION) request, and the kernel logs 'unable to read
config index 0 descriptor/start: -71'.
The device then falls back to a secondary Android HID mode (with a
different VID:PID), losing XInput functionality including rumble support.
The failure reproduces across multiple machines, host controller types, and
kernel versions including current mainline and LTS. The device enumerates
correctly and remains in XInput mode under Windows. Notably, the device
enumerates correctly in Android mode when the same 9-byte request
is issued for that mode's configuration descriptor, confirming the firmware
bug is specific to the XInput mode.
usbmon traces from Linux and Wireshark/USBPcap traces from Windows are
identical up to the point of failure, with no visible protocol-level
difference explaining the divergence. The root cause was identified when
Michal Pecio discovered via a QEMU bus-level capture that Windows does not
use wLength=9 for the initial config descriptor request; it uses
wLength=255. Alan Stern subsequently confirmed this with a bus
analyzer on a different USB 2.0 device, and Michal verified the behavior
goes back to Windows 95 OSR2.1.
So, add a new quirk flag USB_QUIRK_WINDOWS_CONFIG_REQ_SIZE which causes
usb_get_configuration() to issue a 255 byte sized configuration request
instead of USB_DT_CONFIG_SIZE (9) for the initial
GET_DESCRIPTOR(CONFIGURATION) request, mimicking long-standing Windows
behavior.
This patch intentionally does not add any new VID:PID entries using this
quirk. Some affected Xbox 360-compatible controllers spoof Microsoft's
VID:PID, while genuine Microsoft controllers already enumerate correctly
and do not require this quirk. Other affected clone devices use their own
VID:PID pairs and can be added individually as they are identified.

behavior
io.latency is documented only in terms of average latency and the avg_lat
stat, which matches rotational devices. On non-rotational devices a group
misses its target once enough of the IOs in the window individually exceed
it, and io.stat reports missed/total rather than avg_lat/win.
Describe both cases: how a miss is detected, note that the avg_lat tuning
guidance is rotational-only, and update the io.stat field list (mark
avg_lat/win as rotational-only, document missed/total).

Large keepalive values can overflow the delayed-work delay on 32-bit
systems, causing the keepalive worker to be repeatedly scheduled.
A correct configuration should not require such large keepalive values,
and an upper limit of one day is already generous and unnecessary in
practice. Limit both the keepalive interval and timeout to 86400 seconds.

- fix a 7.2-rc regression in the adapter interrupt mapping code
|
|
FOLL_LONGTERM pinning fails for some memory types, such as file-backed
guest memory. As a result, kvm_s390_adapter_map() returns -EINVAL and
irqfd adapter registration fails even though interrupt delivery could
still work via the existing non-atomic path.
When FOLL_LONGTERM pinning fails, verify that the page is accessible
using a short-term pin instead. If the short-term pin succeeds, unpin
the page and add a map entry with pinned=false to preserve MAP/UNMAP
symmetry. The non-atomic irqfd path already performs short-term pinning
for interrupt delivery, so this restores the previous behavior for
memory that cannot be pinned long-term.
get_map_info() is updated to return NULL for unpinned entries so that
the atomic irqfd fast path falls back to the non-atomic path.
kvm_s390_adapter_unmap() and kvm_s390_unmap_all_adapters() skip dirty
marking and unpin for unpinned entries.
Update Documentation/virt/kvm/devices/s390_flic.rst to reflect the
new MAP/UNMAP behavior.

The zero-copy Tx batch parser stops when it encounters an invalid
descriptor. If this happens after one or more continuation descriptors,
the Tx consumer can be advanced past fragments that are neither submitted
to the driver nor returned to userspace through the completion ring.
A similar problem occurs when a packet exceeds xdp_zc_max_segs. The
descriptors consumed up to the limit are released without completion, and
the remaining continuation descriptors can subsequently be interpreted
as the beginning of another packet.
Parse Tx batches in packet units and distinguish descriptors belonging to
complete valid packets from descriptors consumed while draining an
invalid or oversized packet. Return the former to the driver and append
the latter to the CQ address area so userspace can reclaim their UMEM
frames.
Treat a standalone invalid descriptor as a one-descriptor reclaim-only
packet. Advancing the Tx-ring consumer releases the ring slot, but does
not by itself return ownership of the referenced UMEM frame to userspace.
Once draining starts, continue until the packet's end-of-packet
descriptor is consumed. Preserve the drain state on the socket when EOP
has not yet been supplied, so draining can continue during a later call.
Leave incomplete but otherwise valid packets on the Tx ring.
Shared-UMEM pools using multi-buffer Tx also need packet-framed parsing.
Walk their Tx sockets one packet at a time, preserving the existing
per-socket fairness scheme, instead of using the legacy one-descriptor
fallback. Keep that fallback for shared pools that do not use
multi-buffer Tx. Since the drain state is maintained per socket and both
the singular and shared paths can resume an interrupted drain, changing
the socket list from singular to shared requires no special bind-time
transition.
CQ entries are positional, and drivers may complete only part of the Tx
work returned by xsk_tx_peek_release_desc_batch(). Therefore, reclaim-only
entries cannot be published immediately when earlier driver-visible
descriptors are still outstanding.
Track the number of driver-visible CQ entries preceding the reclaim
entries. Let xsk_tx_completed() publish partial hardware Tx completions,
and publish the reclaim entries only after every earlier Tx descriptor
has completed. Complete a reclaim-only batch immediately when there is no
driver-visible work in front of it, and prevent another Tx batch from
being appended while reclaim entries remain pending.
Also cap batch processing by the size of the pool's temporary descriptor
array, as Tx rings belonging to sockets sharing a UMEM may have different
sizes.
This ensures that every invalid Tx descriptor consumed by the ZC batch
path is either submitted to the driver as part of a valid packet or
returned to userspace without violating CQ completion ordering.

The user cannot use MTE on VMAs created by mapping a guest_memfd file,
as arch_calc_vm_flag_bits() does not set VM_MTE_ALLOWED.
When creating a guest_memfd backed memslot,
kvm_arch_prepare_memory_region() rejects the memslot if MTE is enabled for
the VM and if guest_memfd has been mapped in a VMA that intersects the
memslot.
However, the documentation for KVM_SET_USER_MEMORY_REGION2 explicitly
states that the only condition for userspace_addr is for it to be a legal
userspace address, but the mapping is not required to be valid nor
populated at memslot creation.
If userspace sets userspace_addr to an address that hasn't been mapped, or
if userspace_addr belongs to a VMA that isn't backed by the guest_memfd
file, or if the VMA doesn't intersect the memslot, memslot creation is
successful and KVM ends up with a VM with MTE and guest_memfd-backed
memslots.
The same happens if the order is reversed: when userspace enables MTE, KVM
does not check if memslots backed by guest_memfd are already present.
Fix both issues by rejecting guest_memfd-backed memslots when MTE is
enabled, and by rejecting MTE when guest_memfd-backed memslots are already
present.

In the nested state, the physical interrupt has already been
deactivated through the HW bit in the LR. The extra deactivation
would be harmless but can hit an errata case on AmpereOne, so
avoid it here.
On AmpereOne, deactivating a physical interrupt through
ICC_DIR_EL1 or ICC_EOIR1_EL1 (depending on EOImode) which is not
active, but is the highest priority pending interrupt causes the
cpu to lose the interrupt pending state and also prevents the
delivery of future interrupts.

A number of IFLA_BRPORT_* attributes are documented in the rt-link spec
as having the "flag" type, i.e. a payload-less NLA_FLAG attribute whose
meaning is presence-only. This does not match the kernel, which emits
these attributes with nla_put_u8() and validates them as NLA_U8 in
br_port_policy[]. The values are not mere presence flags but carry a u8
payload (0/1).
Convert these bridge port attributes from "flag" to "u8" so the spec
reflects the actual wire format.

Pull RISC-V fixes from Paul Walmsley:
"The most notable change involves the rseq kselftest common Makefile
(as it is not RISC-V-specific). The basic approach in the patch
appears similar to one used in the KVM and S390 selftests (grep for
LINUX_TOOL_ARCH_INCLUDE and SUBARCH), and the rseq kselftests pass a
quick build test on x86 after this.
- Avoid a null pointer deference in machine_kexec_prepare() that the
IMA subsystem can trigger
- Bypass libc in part of the ptrace_v_not_enabled kselftest to avoid
noise from child atfork handlers that libc might run
- Include Kconfig support for UltraRISC SoCs, already referenced by
some device drivers; and enable it in our defconfig
- Fix the build of the rseq kselftest for RISC-V by borrowing a

My legal and preferred first names are SeongJae and SJ, respectively. I
was using the legal name for commits and tags, while using the preferred
name for conversations. It sometimes confuses people including myself.
Consistently use the preferred name.
Together remove copyright notes on files. Those are only confusing for
people who are not familiar with the law. Meanwhile, we can infer the
information in a better way from git logs and public information.

Make it clear that lib/crypto/ is a kernel-internal library. It's easy
for people to come across this page, especially the HTML version online,
without that context.

Currently, the section about the library API for each algorithm begins
with a noun phrase that was intended to serve as an elaboration on the
title. It's better to use complete sentences.

A handful of vendor-extension entries indent continuation lines with a
tab character, while the rest of hwprobe.rst uses spaces. In addition,
many list items align their continuation lines under the 'm' of
':c:macro:' (column 7) rather than under the item text (column 4), so
the file mixes several indentation styles.
Replace the tabs with spaces and align every list item's continuation
lines under the item text, giving the whole file one consistent style.
Whitespace-only change, no functional change.
[Guodong: extend from tabs->spaces to normalizing all continuation-line
indentation across the file]

The multi-letter extension enum is documented as being sorted
alphanumerically (see the "multi-letter extensions, sorted
alphanumerically" comment), but several Z entries have drifted out of
order.
Reorder the affected entries so the multi-letter Z list is sorted
alphanumerically again.

The io.stat section says that enabling the io.latency controller exposes
the depth, avg_lat and win stats in addition to the normal ones. However,
these io.latency-specific stats are debug stats and are only emitted when
the blkcg_debug_stats module parameter is enabled, which is disabled by
default.
Make this explicit so users do not expect these fields to appear in
io.stat by default, and qualify the usage text that suggests using
avg_lat to pick an io.latency target.

rdma.events.local
The v1 RDMA controller documentation only describes rdma.max and
rdma.current, but the controller exposes three more files -- rdma.peak,
rdma.events and rdma.events.local -- which are already documented for
v2. Mirror the v2 wording so the v1 documentation matches the files
actually visible on a v1 mount.
