Add a single kselftest covering the proto_ops getsockopt_iter
conversions for AF_NETLINK and AF_VSOCK, using one fixture per protocol:
netlink:
NETLINK_PKTINFO covers the flag-style int path (exact size, oversize
clamp, undersize -EINVAL); NETLINK_LIST_MEMBERSHIPS covers the
size-discovery path that always reports the required buffer length back
via optlen, even when the user buffer is too small to receive any group
bits.
vsock:
SO_VM_SOCKETS_BUFFER_SIZE covers the u64 path (exact size, oversize
clamp, undersize -EINVAL).
Each fixture also exercises an unknown optname and a bogus level so
the returned-length / errno semantics preserved by the sockopt_t
conversion are pinned down.

Certain devices which support ntuple-filters do not enable the feature
by default. The existing tests will skip (if they check for the feature),
or fail if they blindly attempt to install rules. Therefore, attempt to turn
on ntuple-filters if the device supports them.

These tests check syncookie mode is able to reconstruct some
client options when TCP TS are used:
- wscale option.
- sackOK.
- MSS (in a limited way, especially for IPv4).
- ECN : not enabled.
Note that IPv4 and IPv6 have different msstab[] values:
IPv4 msstab[4] = { 536, 1300, 1440, 1460 }
IPv6 msstab[4] = { 1280 - 60, 1480 - 60, 1500 - 60, 9000 - 60 }
IPv4 is currently capping SND_MSS to 1460, even on a 9K MTU network.

Add test cases to verify that ARP probes and DAD Neighbor Solicitations
are handled correctly by the bridge neighbor suppression feature.
When neighbor suppression is enabled on a bridge VXLAN port, the bridge
should reply to ARP/NS messages on behalf of remote hosts when both FDB
and neighbor entries exist, and the answer is known. However, when
either the FDB or the neighbor exists, ARP probes / DAD NS should be
treated like regular ARP requests / NS and flood to VXLAN.
Add two new test functions:
neigh_suppress_arp_probe(): Tests ARP probe handling by triggering
duplicate address detection using arping -D. Verifies that probes are
flooded when the bridge doesn't know the answer, and suppressed when FDB
and neighbor entries exist.
neigh_suppress_dad_ns(): Tests DAD NS handling by constructing DAD NS
packets using mausezahn and verifies correct flooding/suppression
behavior.

Currently the kernel's TCP-AO implementation does the MAC and KDF
computations using the crypto_ahash API. This API is inefficient and
difficult to use, and it has required extensive workarounds in the form
of per-CPU preallocated objects (tcp_sigpool) to work at all.
Let's use lib/crypto/ instead. This means switching to straightforward
stack-allocated structures, virtually addressed buffers, and direct
function calls. It also means removing quite a bit of error handling.
This makes TCP-AO quite a bit faster.
This also enables many additional cleanups, which later commits will
handle: removing tcp-sigpool, removing support for crypto_tfm cloning,
removing more error handling, and replacing more dynamically-allocated
buffers with stack buffers based on the now-statically-known limits.

RFC 5926 (https://datatracker.ietf.org/doc/html/rfc5926) specifies the
use of AES-128-CMAC and HMAC-SHA1 with TCP-AO. This includes a
specification for how traffic keys shall be derived for each algorithm.
Support for any other algorithms with TCP-AO isn't standardized, though
an expired Internet Draft (a work-in-progress document, not a standard)
from 2019 does propose adding HMAC-SHA256 support:
https://datatracker.ietf.org/doc/html/draft-nayak-tcp-sha2-03
Since both documents specify the KDF for each algorithm individually, it
isn't necessarily clear how any other algorithm should be integrated.
Nevertheless, the Linux implementation of TCP-AO allows userspace to
specify the MAC algorithm as a string tcp_ao_add::alg_name naming either
"cmac(aes128)" or an arbitrary algorithm in the crypto_ahash API. The
set of valid strings is undocumented. The implementation assumes that
"cmac(aes128)" is the only algorithm that requires an entropy extraction
step and that all algorithms accept keys with length equal to the
untruncated MAC; thus, arbitrary HMAC algorithms probably do work, but
some other MAC algorithms like AES-256-CMAC have never actually worked.
Unfortunately, this undocumented string allows many obsolete, insecure,
or redundant algorithms. For example, "hmac(md5)" and the
non-cryptographic "crc32" are accepted. It also ties the implementation
to crypto_ahash and requires that most memory be dynamically allocated,
making the implementation unnecessarily complex and inefficient. Still
furthermore, this implementation requires the crypto API to support
"transformation cloning", whose only user is this feature.
Fortunately, it's very likely that only a few algorithms are actually
used in practice. Let's restrict the set of allowed algorithms to
"cmac(aes128)" (or "cmac(aes)" with keylen=16), "hmac(sha1)", and
"hmac(sha256)". The first two are the actually standard ones, while
HMAC-SHA256 seems like a reasonable algorithm to continue supporting as
a Linux extension, considering the Internet Draft for it and the fact
that SHA-256 is the usual choice of upgrade from the outdated SHA-1.
If any other algorithm ever turns out to be needed, e.g. HMAC-SHA512, it
can of course be (re-)added in library form. However, note that the TCP
options space limits TCP-AO MACs to 20 bytes (160 bits) anyway, which
limits the potential benefit of any further upgrade to the algorithm.

arm64:
- Allow tracing for non-pKVM, which was accidentally disabled when
the series was merged
- Rationalise the way the pKVM hypercall ranges are defined by using
the same mechanism as already used for the vcpu_sysreg enum
- Enforce that SMCCC function numbers relayed by the pKVM proxy are
actually compliant with the specification
- Fix a couple of feature to idreg mappings which resulted in the
wrong sanitisation being applied
- Fix the GICD_IIDR revision number field that could never been
written correctly by userspace
- Make kvm_vcpu_initialized() correctly use its parameter instead of
relying on the surrounding context
- Enforce correct ordering in __pkvm_init_vcpu(), plugging a
potential pin leak at the same time
- Move __pkvm_init_finalise() to a less dangerous spot, avoiding
future problems
- Restore functional userspace irqchip support after a four year
breakage (last functional kernel was 5.18...)
- Spelling fixes
Selftests:

Pull sched_ext fixes from Tejun Heo:
"The merge window pulled in the cgroup sub-scheduler infrastructure,
and new AI reviews are accelerating bug reporting and fixing - hence
the larger than usual fixes batch:
- Use-after-frees during scheduler load/unload:
- The disable path could free the BPF scheduler while deferred
irq_work / kthread work was still in flight
- cgroup setter callbacks read the active scheduler outside the
rwsem that synchronizes against teardown
Fix both, and reuse the disable drain in the enable error paths so
the BPF JIT page can't be freed under live callbacks.
- Several BPF op invocations didn't tell the framework which runqueue
was already locked, so helper kfuncs that re-acquire the runqueue
by CPU could deadlock on the held lock
Fix the affected callsites, including recursive parent-into-child
dispatch.
- The hardlockup notifier ran from NMI but eventually took a
non-NMI-safe lock. Bounce it through irq_work.
- A handful of bugs in the new sub-scheduler hierarchy:
- helper kfuncs hard-coded the root instead of resolving the
caller's scheduler
- the enable error path tried to disable per-task state that had
never been initialized, and leaked cpus_read_lock on the way
out
- a sysfs object was leaked on every load/unload
- the dispatch fast-path used the root scheduler instead of the
task's
- a couple of CONFIG #ifdef guards were misclassified
- Verifier-time hardening: BPF programs of unrelated struct_ops types
(e.g. tcp_congestion_ops) could call sched_ext kfuncs - a semantic
bug and, once sub-sched was enabled, a KASAN out-of-bounds read.
Now rejected at load. Plus a few NULL and cross-task argument
checks on sched_ext kfuncs, and a selftest covering the new deny.
- rhashtable (Herbert): restore the insecure_elasticity toggle and
bounce the deferred-resize kick through irq_work to break a
lock-order cycle observable from raw-spinlock callers. sched_ext's
scheduler-instance hash is the first user of both.
- The bypass-mode load balancer used file-scope cpumasks; with
multiple scheduler instances now possible, those raced. Move to
per-instance cpumasks, plus a follow-up to skip tasks whose
recorded CPU is stale relative to the new owning runqueue.
- Smaller fixes:
- a dispatch queue's first-task tracking misbehaved when a parked
iterator cursor sat in the list
- the runqueue's next-class wasn't promoted on local-queue
enqueue, leaving an SCX task behind RT in edge cases
- the reference qmap scheduler stopped erroring on legitimate
cross-scheduler task-storage misses"

Add a regression test for the NULL pointer dereference fixed in the
previous commit. Before the fix, taprio_graft() stored NULL into
q->qdiscs[cl - 1] when an explicitly grafted child qdisc was deleted
via RTM_DELQDISC; the next RTM_GETTCLASS dump then crashed the kernel
in taprio_dump_class() while reading child->handle.
The test installs a taprio root qdisc on a multi-queue netdevsim
device, grafts a pfifo child onto class 8001:1, deletes that child,
and then performs a class dump. On a fixed kernel the dump succeeds
and all eight taprio classes are listed; on an unpatched kernel the
class dump crashes, which surfaces as a test failure.

KVM selftests type renames for 7.1
Renames types across all KVM selftests to more closely align with types used
in the kernel:
vm_vaddr_t -> gva_t
vm_paddr_t -> gpa_t
uint64_t -> u64
uint32_t -> u32
uint16_t -> u16
uint8_t -> u8
int64_t -> s64
int32_t -> s32
int16_t -> s16
int8_t -> s8
Using the kernel's preferred types eliminates a source of friction for many
contributors, as the majority of KVM selftests contributions come from kernel
developers. The kernel names are also shorter, which allows for more concise
code, and in any many cases eliminates newlines thanks to shorter types and
parameter names.
Rename variables and parameters as well as types, e.g. gpa instead of paddr,
to again align with the kernel, and in a few cases to remove ambiguity, e.g.
where paddr is used to refer to a _host_ physical address.

Pull RISC-V updates from Paul Walmsley:
"There is one significant change outside arch/riscv in this pull
request: the addition of a set of KUnit tests for strlen(), strnlen(),
and strrchr().
Otherwise, the most notable changes are to add some RISC-V-specific
string function implementations, to remove XIP kernel support, to add
hardware error exception handling, and to optimize our runtime
unaligned access speed testing.
A few comments on the motivation for removing XIP support. It's been
broken in the RISC-V kernel for months. The code is not easy to
maintain. Furthermore, for XIP support to truly be useful for RISC-V,
we think that compile-time feature switches would need to be added for
many of the RISC-V ISA features and microarchitectural properties that
are currently implemented with runtime patching. No one has stepped
forward to take responsibility for that work, so many of us think it's
best to remove it until clear use cases and champions emerge.
Summary:
- Add Kunit correctness testing and microbenchmarks for strlen(),
strnlen(), and strrchr()
- Add RISC-V-specific strnlen(), strchr(), strrchr() implementations
- Add hardware error exception handling
- Clean up and optimize our unaligned access probe code
- Enable HAVE_IOREMAP_PROT to be able to use generic_access_phys()

Pull networking fixes from Jakub Kicinski:
"Including fixes from Netfilter.
Steady stream of fixes. Last two weeks feel comparable to the two
weeks before the merge window. Lots of AI-aided bug discovery. A newer
big source is Sashiko/Gemini (Roman Gushchin's system), which points
out issues in existing code during patch review (maybe 25% of fixes
here likely originating from Sashiko). Nice thing is these are often
fixed by the respective maintainers, not drive-bys.
Current release - new code bugs:
- kconfig: MDIO_PIC64HPSC should depend on ARCH_MICROCHIP
Previous releases - regressions:
- add async ndo_set_rx_mode and switch drivers which we promised to
be called under the per-netdev mutex to it
- dsa: remove duplicate netdev_lock_ops() for conduit ethtool ops
- hv_sock: report EOF instead of -EIO for FIN
- vsock/virtio: fix MSG_PEEK calculation on bytes to copy
Previous releases - always broken:
- ipv6: fix possible UAF in icmpv6_rcv()
- icmp: validate reply type before using icmp_pointers
- af_unix: drop all SCM attributes for SOCKMAP
- netfilter: fix a number of bugs in the osf (OS fingerprinting)

RFC 5961 Section 5.2 / RFC 793 Section 3.9 require a challenge ACK
whenever an incoming SEG.ACK falls outside
[SND.UNA - MAX.SND.WND, SND.NXT]. There is currently no packetdrill
coverage for either edge.
Add tcp_rfc5961_ack-out-of-window.pkt, which in a single passive-open
connection exercises:
- Upper edge (SEG.ACK > SND.NXT): peer ACKs data that was never
sent before the server has transmitted anything.
- Lower edge (SEG.ACK < SND.UNA - MAX.SND.WND): after the server
has sent 2000 bytes (the peer-advertised rwnd forces two 1000-byte
segments, both acknowledged), peer sends an ACK that is older
than the acceptable window.
Both cases must elicit a challenge ACK
<SEQ = SND.NXT, ACK = RCV.NXT, CTL = ACK>. The per-socket RFC 5961
Section 7 rate limit is disabled for the duration of the test so that
both challenge ACKs can fire back-to-back.

RFC 5961 Section 5.2 validates an incoming segment's ACK value
against the range [SND.UNA - MAX.SND.WND, SND.NXT] and states:
"All incoming segments whose ACK value doesn't satisfy the above
condition MUST be discarded and an ACK sent back."
Commit 354e4aa391ed ("tcp: RFC 5961 5.2 Blind Data Injection Attack
Mitigation") opted Linux into this mitigation and implements the
challenge ACK on the lower side (SEG.ACK < SND.UNA - MAX.SND.WND),
but the symmetric upper side (SEG.ACK > SND.NXT) still takes the
pre-RFC-5961 path and silently returns
SKB_DROP_REASON_TCP_ACK_UNSENT_DATA, even though RFC 793 Section 3.9
(now RFC 9293 Section 3.10.7.4) has always required:
"If the ACK acknowledges something not yet sent (SEG.ACK > SND.NXT)
then send an ACK, drop the segment, and return."
Complete the mitigation by sending a challenge ACK on that branch,
reusing the existing tcp_send_challenge_ack() path which already
enforces the per-socket RFC 5961 Section 7 rate limit via
__tcp_oow_rate_limited(). FLAG_NO_CHALLENGE_ACK is honoured for
symmetry with the lower-edge case.
Update the existing tcp_ts_recent_invalid_ack.pkt selftest, which
drives this exact path, to consume the new challenge ACK.

The end-to-end integrity ublk selftest test_integrity_02 requires a
relatively recent fio version to support I/O with integrity buffers. Add
a version test_integrity_03 that uses the block layer's auto integrity
path instead. The auto integrity code doesn't check the application tag,
and doesn't indicate the bad guard/ref tag (just returns EILSEQ). But
it's a good smoke-test of the ublk integrity code and provides coverage
of the auto integrity path as well.

Pull ktest updates from Steven Rostedt:
- Fix month in date timestamp used to create failure directories
On failure, a directory is created to store the logs and config file
to analyze the failure. The Perl function localtime is used to create
the data timestamp of the directory. The month passed back from that
function starts at 0 and not 1, but the timestamp used does not
account for that. Thus for April 20, 2026, the timestamp of 20260320
is used, instead of 20260420.
- Save the logfile to the failure directory
Just the test log was saved to the directory on failure, but there's
useful information in the full logfile that can be helpful to
analyzing the failure. Save the logfile as well.

Replace teamd daemon usage with ip link commands for team device
setup. teamd -d daemonizes and returns to the shell before port
addition completes, creating a race: the test may create the macvlan
(and check for its address on a slave) before teamd has finished
adding ports. This makes the test inherently dependent on scheduling
timing.
Using ip commands makes port addition synchronous, removing the race
and making the test deterministic.
