selftests/rseq: Validate legacy behavior
The RSEQ legacy mode behavior requires that the ID fields in the rseq
region are unconditionally updated on every context switch and before
signal delivery even if not required by the ABI specification.
To ensure that this behavior is preserved for legacy users in the future,
add a test which validates that with a sleep() and a signal sent to self.
Provide a run script which prevents GLIBC from registering a RSEQ region,
so that the test can register it's own legacy sized region.

selftests/rseq: Make registration flexible for legacy and optimized mode
rseq_register_current_thread() either uses the glibc registered RSEQ region
or registers it's own region with the legacy size of 32 bytes.
That worked so far, but becomes a problem when the kernel implements a
distinction between legacy and performance optimized behavior based on the
registration size as that does not allow to test both modes with the self
test suite.
Add two arguments to the function. One to enforce that the registration is
not using libc provided mode and one to tell the registration to use the
legacy size and not the kernel advertised size.
Rename it and make the original one a inline wrapper which preserves the
existing behavior.

selftests/rseq: Don't run tests with runner scripts outside of the scripts
The rseq selftests include two runner scripts run_param_test.sh and
run_syscall_errors_test.sh which set up the environment for test binaries
and run them with various parameters. Currently we list these test binaries
in TEST_GEN_PROGS but this results in the kselftest framework running them
directly as well as via the runners, resulting in duplication and spurious
failures when the environment is not correctly set up (eg, if glibc tries
to use rseq).
Move the binaries the runners invoke to TEST_GEN_PROGS_EXTENDED, binaries
listed there are built but not run by the framework. The param_test
benchmarks are not moved since they are not run by run_param_test.sh.

Check that the driver actually registered the profile named "SoC Slider" before reading or writing these modparams. n.b.

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

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)
- eth: intel: fix timestamp interrupt configuration for E825C

selftests/bpf: check epoll readiness during reuseport migration
Inside migrate_dance(), add epoll checks around shutdown() to verify that the target listener is not ready before shutdown() and becomes ready immediately after shutdown() triggers migration. Cover TCP_ESTABLISHED and TCP_SYN_RECV. Exclude TCP_NEW_SYN_RECV as it depends on later handshake completion.

selftests/net: packetdrill: cover RFC 5961 5.2 challenge ACK on both edges
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.

selftests: ublk: add ublk auto integrity test
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.

tools/power turbostat: Fix --cpu-set 1 regression on HT systems
When the "--cpu-set" option limits turbostat to run on
a higher numbered HT sibling, it exits upon dividing by zero.
This is because the HT support handles higher numbered siblings
at the same time as lower numbered siblings. But when that lower
number sibling is dis-allowed, the higher numbered sibling is
never processed. The result is a time delta of 0, which results
in a divide by 0 for any of the "per-second" metrics.
Enhance the HT enumeration code to record all siblings (up to SMT4).
Consult this complete HT sibling list to determine when
to process an HT sibling, and when to skip it.

tools/power turbostat: Fix --cpu-set 0 regression on HT systems
"turbostat --cpu-set 0" appears to hang if cpu0 has an HT sibling.
This is because the initialization code recognizes that it does not
have to open perf files for the HT sibling, but the HT support
in the collection code sees the HT sibling and tries to read
from an uninitialized file descriptor, 0 (standard input).
Access HT siblings only when they are in the allowed set.

Probes fixes for v7.1
- fprobe: Fixed several bugs, which includes followings:
. Prevention of re-registration: Added an earlier check to reject
re-registering an already active fprobe before its state is modified
during the initialization phase.
. Robustness in failure paths:
- Ensured fprobes are correctly removed from all internal tables and
properly RCU-freed during registration failure.
- Modified unregister_fprobe() to proceed with unregistration even if
temporary memory allocation fails.
. RCU safety in module unloading: Avoided a potential "sleep in RCU"
warning by removing a kcalloc() call in the module notifier path. This
also tries to remove fprobe_hash_node even if memory allocation fails.
. Type-aware unregistration: Fixed a bug where unregistering an fprobe
did not account for different types (entry-only vs. entry-exit) at the
same address, which previously left "junk" entries in the underlying
ftrace/fgraph ops.
. Unregistration of empty ftrace_ops: Avoided unneeded performance
overhead because of making registered ftrace_ops empty (means trace
all functions.) This counts remaining entries and unregister ftrace_ops
when it becomes empty.
- ftracetest: In addition to the fix, two new selftests to check above
fixes, are included:
. Module Unloading Test: Specifically verifies that fprobe events on
a module are correctly cleaned up and do not trigger "trace-all"
behavior when the module is removed.
. Multiple Fprobe Events Test: Ensures that having multiple fprobes on
the same function correctly manages the ftrace hash map during
removal.

ktest: Fix the month in the name of the failure directory
The Perl localtime() function returns the month starting at 0 not 1. This
caused the date produced to create the directory for saving files of a
failed run to have the month off by one.
machine-test-useconfig-fail-20260314073628
The above happened in April, not March. The correct name should have been:
machine-test-useconfig-fail-20260414073628
This was somewhat confusing.

USB / Thunderbolt changes for 7.1-rc1
Here is the big set of USB and Thunderbolt changes for 7.1-rc1.
Lots of little things in here, nothing major, just constant
improvements, updates, and new features. Highlights are:
- new USB power supply driver support (will cause merge conflicts in
drivers/power/supply/Makefile, but it's a simple fix) These changes
did touch outside of drivers/usb/ but got acks from the relevant
mantainers for them.
- dts file updates and conversions
- string function conversions into "safer" ones
- new device quirks
- xhci driver updates
- usb gadget driver minor fixes
- typec driver additions and updates
- small number of thunderbolt driver changes
- dwc3 driver updates and additions of new hardware support
- other minor driver updates
All of these have been in the linux-next tree for a while with no
reported issues

docs: kdoc: Expand 'at_least' when creating parameter list
sphinx doesn't know that the kernel headers do:
#define at_least static
Do this replacement before declarations are passed to it.
This prevents errors like the following from appearing once the

perf tools updates for 7.1
perf report:
- Add 'comm_nodigit' sort key to combine similar threads that only have
different numbers in the comm. In the following example, the
'comm_nodigit' will have samples from all threads starting with
"bpfrb/" into an entry "bpfrb/<N>".

- Support flat layout for symfs. The --symfs option is to specify the
location of debugging symbol files. The default 'hierarchy' layout
would search the symbol file using the same path of the original file
under the symfs root. The new 'flat' layout would search only in the
root directory.
- Update 'simd' sort key for ARM SIMD flags to cover ASE/SME and more
predicate flags.
perf stat:
- Add --pmu-filter option to select specific PMUs. This would be
useful when you measure metrics from multiple instance of uncore PMUs
with similar names.

selftests: mm: skip charge_reserved_hugetlb without killall
charge_reserved_hugetlb.sh tears down background writers with killall from psmisc. Minimal Ubuntu images do not always provide that tool, so the selftest fails in cleanup for an environment reason rather than for the hugetlb behavior it is trying to cover. Skip the test when killall is unavailable, similar to the existing root check, so these environments report the dependency clearly instead of failing the test.
