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.

tracing fixes for 7.2:
- Free field in error path of synthetic event parse In __create_synth_event() the field was allocated but was not freed in the error path. - Fix ring_buffer_event_length() on 8 byte aligned architectures On architectures with CONFIG_HAVE_64BIT_ALIGNED_ACCESS set to y, the ring_buffer_event_length() may return the wrong size. This is because archs with that config set will always use the "big event meta header" as that is 8 bytes keeping the payload 8 bytes aligned, even when a 4 byte header could hold the size of the event. But ring_buffer_event_length() doesn't take this into account and only subtracts 4 bytes for the meta header in the length when it should have subtracted 8 bytes. - Have osnoise wait for a full rcu synchronization on unregister osnoise_unregister_instance() used to call synchronize_rcu() before freeing its copy of the instance but was switched to kfree_rcu(). The osniose tracer has code that traverses the instances that it uses, and inst is just a pointer to that instance. By using kfree_rcu() instead of synchronize_rcu(), the instance that the inst pointer is pointing to can be freed while the osnoise code is still referencing it. That is, a rmdir on an instance first unregisters the tracer. When the unregister finishes, the rmdir expects that the tracer is finished with the instance that it is using. By putting back the synchronize_rcu() in osnoise_unregister_instance() the unregistering of osnoise will now return when all the users of the instance have finished. - Remove an unused setting of "ret" in tracing_set_tracer() - Fix ring_buffer_read_page() copying events The commit that changed ring_buffer_read_page() to show dropped events from the buffer itself, split the "commit" variable between the commit value (with flags) and "size" that holds the size of the sub-buffer. A cut and paste error changed the test of the reading from checking the size of the buffer to the size of the event causing reads to only read one event at a time. - Make tracepoint_printk a static variable When the tracing sysctl knobs were move from sysctl.c to trace.c, the variable tracepoint_printk no longer needed to be global. Make it static. - Fix some typos - Fix NULL pointer dereference in func_set_flag() The flags update of the function tracer first checks if the value of the flag is the same and exits if they are, and then it checks if the current tracer is the function tracer and exits if it isn't. The problem is that these checks need to be in a reversed order, as if the tracer isn't the function tracer, then the flag being checked may not exist. Reverse the order of these checks. - Fix ufs core trace events to not dereference a pointer in TP_printk() The TP_printk() part of the TRACE_EVENT() macro is called when the user reads the "trace" file. This can be seconds, minutes, hours, days, weeks, and even months after the data was recorded into the ring buffer. Thus, saving a pointer to an object into the ring buffer and then dereferencing it from TP_printk() can cause harm as the object the pointer is pointing to may no longer exist. Fix all the trace events in ufs core to save the device name in the ring buffer instead of dereferencing the device descriptor from TP_printk(). - Prevent out-of-bound reads in glob matching of trace events The filter logic of events allows simple glob logic to add wild cards to filter on strings. But some events have fields that may not have a terminating 'nul' character. This may cause the glob matching to go beyond the string. Change the logic to always pass in the length of the field that is being matched. - Add no-rcu-check version of trace_##event##_enabled() The trace_##event##_enabled() usually wraps trace events to do extra work that is only needed when the trace event is enabled. But this can hide events that are placed in locations where RCU is not watching, and can make lockdep not see these bugs when the event is not enabled. The trace_##event##_enabled() was updated to always test to make sure RCU is watching to catch locations that may call events without RCU being active. This caused a false positive for the irq_disabled() and related events. As that use trace_irq_disabled_enabled() to force RCU to be watching when the event is enabled via the ct_irq_enter() function, calls the event, and then calls ct_irq_exit() to put RCU back to its original state. The trace_irq_disabled_enabled() should not trigger a warning when RCU is not watching because the code within its block handles the case properly. Make a __trace_##event##_enabled() version for this event to use that doesn't check RCU is watching as it handles the case when it isn't. - Fix use-after-free in user_event_mm_dup() When the enabler is removed from the link list, it is freed immediately. But it is protected via RCU and needs to be freed after an RCU grace period. Use queue_rcu_work() so that the event_mutex can also be taken as user_event_put() takes the mutex on the last reference is released. - Free type string in error path of parse_synth_field() There's an error path in parse_synth_field() where the allocated type string is not freed. - Add selftest that tests deferred event teardown - Fix leak in error path of trace_remote_alloc_buffer() If page allocation fails, the desc->nr_cpus is not incremented for the current CPU and the allocations done for it are not freed. - Fix allocation length in trace_remote_alloc_buffer() The logic to calculate the struct_len was doing a double count and setting the value too large. Calculate the size upfront to fix the error and simplify the logic. - Fix sparse CPU masks in ring_buffer_desc() If there are sparse CPUs (gaps in the numbering), the ring_buffer_desc() will fail as it tests the CPU number against the number of CPUs that are used. -----BEGIN PGP SIGNATURE----- iQJIBAABCgAyFiEEXtmkj8VMCiLR0IBM68Js21pW3nMFAmpTv/cUHHJvc3RlZHRA Z29vZG1pcy5vcmcACgkQ68Js21pW3nN80w/9HEbliUUrJVNw8QCY8BmeBEzfCRhZ 2CeDzTg+UrLMb2BtqUhA9EjQnRPawe8mPxAfpZ750SdFnCkRhbfNwYmKar3M/8iW y2Bhsvd3Hz6nRiHvKhG/1RkflgKOWLYf/TQSByKlakYLV8t4uffa0fe0N0zcnikK XPGrhrTeRDJ7s94vb1u7p7mSSp2iy4ZhfXbagk966X3I4zvseIYNn5IIzyM3IIPT M7mE60SxvgSRz0QqTJqihmqjXYSeNOQ2iU18wnvp4QfcT0IVuLKm027JnK/YpjWS ZasMNGzO1kp5uo6hkXLrMlT3LjaNEMFTGogs1m9o9auhbMf443LK8GtZ1m1rwnTG cXn1PocBevQIaXWPbnxMrSwIuN7YMUqjgX6SCxbXpDxSSuE5i/x1VmE08CjxnSm6 TdAdom9bE44FvMgaAz9+KhIUgm013c2rFDNiFroYtfkma5FqpfnfglA4/TkJvexY e2L75cR3lrDEDiXXMQDndmvxNMhppwNlAH3mOZLiaCmGyFQFHhgAaG250K2Y6a5K HtIfJkT6RQ3rWifV0E0+zlyRiOrvVCCA8WwNArWb1dTWrVU86Hr7q58jAq9p0Yrz FnhpjdE3eWoUHZ5f28AMR2k5lMG3o6mOGT55JyUVCLw+rPSG5358UIg2xZiEo22k RFlT26FFHbMW50Y= =+//w -----END PGP SIGNATURE----- Merge tag 'trace-v7.2-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing fixes from Steven Rostedt: - Free field in error path of synthetic event parse In __create_synth_event() the field was allocated but was not freed in the error path - Fix ring_buffer_event_length() on 8 byte aligned architectures On architectures with CONFIG_HAVE_64BIT_ALIGNED_ACCESS set to y, the ring_buffer_event_length() may return the wrong size.

xfs: fix null pointer dereference in tracepoint
If dfp is not NULL we exit early here, when dfp is NULL it's allocated
in xfs_defer_alloc() but not assigned. The tracepoint tries to
dereference members of dfp struct.

x86/boot: Reject too long acpi_rsdp= values
cmdline_find_option() returns the full length of the parsed acpi_rsdp=
value. get_cmdline_acpi_rsdp() then silently truncates values which do
not fit in the val[] buffer.
Prevent boot_kstrtoul() from parsing a truncated value and then the
kernel from silently using the wrong RSDP address, see discussion in
Link:.
Issue a warning so that the user is aware that s/he supplied a malformed
value and can get feedback instead of silent crashes.

objtool/rust: add one more noreturn Rust function for Rust 1.99.0
Starting with Rust 1.99.0 (expected 2026-10-01), under
`CONFIG_RUST_DEBUG_ASSERTIONS=y`, `objtool` may report:
rust/kernel.o: warning: objtool: _R..._6kernel12module_param9set_paramaEB4_()
falls through to next function _R..._6kernel12module_param9set_paramhEB4_()
(and many others) due to calls to the `noreturn` symbol [1]:
core::panicking::panic_null_reference_constructed
Thus add the mangled one to the list so that `objtool` knows it is
actually `noreturn`.

rust: zerocopy: update to v0.8.54
Update our vendored copy of `zerocopy` (and `zerocopy-derive`) to v0.8.54.
It is a very small delta from v0.8.52, and most importantly it resolves
the unexpected lack of inlining [1] which triggered a modpost error
under `CONFIG_CC_OPTIMIZE_FOR_SIZE=y` reported by Alexandre using Gary's
suggestion [2]:
ERROR: modpost: "_RNvMNtCs5wX7wwEUCR9_8zerocopy6layoutNtB2_8SizeInfo24try_to_nonzero_elem_size" [drivers/gpu/nova-core.ko] undefined!
ERROR: modpost: "_RNvNtCs5wX7wwEUCR9_8zerocopy4util18padding_needed_for" [drivers/gpu/nova-core.ko] undefined!
It also resolves `most_traits` being unexpectedly documented [3] that I
reported and adds a missing SPDX license identifier [4] that I requested
to match the kernel version.

rust: zerocopy: update to v0.8.52
Update our vendored copy of `zerocopy` (and `zerocopy-derive`) to v0.8.52.
Most SPDX identifiers have been added upstream at our request [1]
(without parentheses -- supporting them is an issue on the kernel side,
but it does already reduce our differences). The CSS one for `rustdoc`
was added too [2], but will be picked up in a later version.
For `zerocopy`, enable `--cfg no_fp_fmt_parse`, which was added at our
request to avoid our local workaround [3]. This means one less difference,
thus indicate so in our `README.md`.
For `zerocopy-derive`, enable `--cfg zerocopy_unstable_linux`. This
allows us to use `#[derive(zerocopy_derive::most_traits)]`, a new feature
upstream added for us [4]. We noticed a minor doc render bug [5], which
will be fixed for a future version too.

macsec: fix promiscuity refcount leak in macsec_dev_open()
When a MACsec interface with IFF_PROMISC set is brought up on top of a
device that has hardware offload enabled, macsec_dev_open() first calls
dev_set_promiscuity(real_dev, 1) and then propagates the open to the
offload device. If that propagation fails, the error path jumps to the
clear_allmulti label, which only reverts allmulti and the unicast
address. The promiscuity taken on the lower device is never dropped, so
real_dev is left permanently stuck in promiscuous mode. Its promiscuity
count can no longer be balanced from software.
Add a clear_promisc label that drops the promiscuity reference and
route the two offload failure paths to it. The dev_set_promiscuity()
failure itself still jumps to clear_allmulti, since on that failure the
count was not incremented.

Steffen Klassert says:
====================
pull request (net): ipsec 2026-07-10
1) xfrm: propagate -EINPROGRESS from validate_xmit_xfrm()
Return -EINPROGRESS from xfrm_output_one when validate_xmit_xfrm
requeues the packet asynchronously, so the caller doesn't treat it
as a real error and free the skb.
2) xfrm: fix stale skb->prev after async crypto steals a GSO segment
Re-derive skb->prev from the fragment list after async crypto splits
a GSO skb, keeping the linked-list pointers validi.
3) xfrm: nat_keepalive: avoid double free on send error
Hold a state ref while the nat_keepalive timer is active and drop the
timer before freeing the state, preventing a re-entered free on send
error.
4) xfrm: fix sk_dst_cache double-free in xfrm_user_policy()
Null the skb dst cache before freeing the policy so a later skb
destructor doesn't double-free it.
5) xfrm: cache the offload ifindex for netlink dumps
Cache the device ifindex at state-add time and use it for netlink
dumps instead of dereferencing dst->dev, which may have changed by
the time the dump runs.
6) xfrm: reject optional IPTFS templates in outbound policies
Reject outbound policies with an optional IPTFS template,
IPTFS must always be used if configured.
7) xfrm: clear mode callbacks after failed mode setup
Clear the mode->init_flags and init_state callbacks on the error path
after xfrm_init_mode fails, so a partially-initialised mode isn't
reused in xfrm_state_construct.
8) xfrm: iptfs: propagate SKBFL_SHARED_FRAG in iptfs_skb_add_frags()
Propagate SKBFL_SHARED_FRAG from the original skb to fragments
allocated by iptfs_skb_add_frags, keeping shared-fragment accounting
correct after IPTFS reassembly.
9) xfrm6: clear dst.dev on error to avoid double netdev_put in xfrm6_fill_dst()
Clear dst->dev on the error path of xfrm6_fill_dst() so the caller

10) xfrm: policy: preallocate inexact bins before xfrm_hash_rebuild reinsert
Preallocate all inexact hash bins before existing entries are
reinserted during xfrm_hash_rebuild, so reinsertion always hits an
existing bin.
Please pull or let me know if there are problems.

perf/x86/amd/brs: Fix kernel address leakage
A user-only branch stack can contain branches that originate from
the kernel. As a result, kernel addresses are exposed to user space
even when PERF_SAMPLE_BRANCH_USER is requested. On AMD processors
supporting X86_FEATURE_BRS (Zen 3 only), perf can still report entries
such as SYSRET/interrupt returns for which the branch-from addresses
are in the kernel.
E.g.
$ perf record -j any,u -c 4000 -e branch-brs -o - -- \
perf bench syscall basic --loop 1000 | \
perf script -i - -F brstack|tr ' ' '\n'| \
grep -E '0x[89a-f][0-9a-f]{15}'
...
0xffffffff810001c4/0x72e2e32955eb/-/-/-/0//-
0xffffffff810001c4/0x72e2d94a9821/-/-/-/0//-
0xffffffff810001c4/0x72e2d94ffa1b/-/-/-/0//-
...
BRS provides no hardware branch filtering, so privilege level
filtering is performed entirely in software. However, amd_brs_match_plm()
only validates the branch-to address against the requested privilege
levels. For branches from the kernel to user space, the branch-from
address is left unchecked and is leaked. Extend the software filter to
also validate the branch-from address, so that any branch record whose
branch-from address is in the kernel is dropped when
PERF_SAMPLE_BRANCH_USER is requested.

Input: mms114 - fix multi-touch slot corruption
If the touchscreen controller reports a touch ID of 0, the driver
calculates the slot ID as touch->id - 1, which underflows to UINT_MAX.
This is passed to input_mt_slot() as -1.
Since the input core ignores negative slot values, the active slot remains
unchanged. The driver then reports the touch coordinates for the previously
active slot, corrupting its state.
Fix this by rejecting touch reports with ID 0.

arc_get_cpu_map() fetches the possible-cpus or present-cpus property from the flat DT and immediately passes the raw pointer to cpulist_parse(). That parser expects a NUL-terminated text buffer, but this path does not prove that the DT property is terminated within its declared bounds.

platform/x86/intel/vsec: free ACPI discovery data on early errors
intel_vsec_add_dev() may attach an ACPI discovery table copy to the
intel_vsec_device before passing ownership to intel_vsec_add_aux(). The
normal auxiliary-device release path frees that copy, but the earliest
intel_vsec_add_aux() failures free only the outer structure directly.
Route those direct frees through a common helper so acpi_disc is
released consistently on the parent, xarray, and ID allocation failure
paths.

sched_ext: Skip ops.set_weight() for disabled tasks
When switching a task's sched_class away from sched_ext, we get the
following sequence of events in __sched_setscheduler():
sched_change_begin()
switched_from_scx()
scx_disable_task(p)
ops.disable(p)
__setscheduler_params()
set_load_weight()
reweight_task_scx(p)
ops.set_weight(p)
p->sched_class = next_class;
sched_change_end()
...
Notably, ops.set_weight() is called _after_ ops.disable().
This violates the expected semantics of the callbacks, the expectation
being that ops.disable() can only be followed by ops.exit_task() or
ops.enable().
Skipping the weight adjustment for disabled tasks should be harmless
since the weight will be recalculated in scx_enable_task() if the task
ever rejoins SCX.

dm-bufio: fix wrong count calculation in dm_bufio_issue_discard
block_to_sector converts a block number to a sector number and adds
c->start to the result. It is inappropriate to use this function for
converting the number of blocks to a number to sectors because c->start
would be incorrectly added to the result.
Luckily, the only target that uses dm_bufio_issue_discard is dm-ebs,
which sets c->start to 0, so this bug is latent.

bug: fix warning suppressions with kunit built as module
CONFIG_KUNIT is a tristate symbol but the warning suppression code in
lib/bug.c is only built if it's built-in due to it using a plain #ifdef,
rendering warning suppressions broken for kunit build as loadable module.
kunit_is_suppressed_warning() already has a stub for when kunit is
disabled so drop that guard entirely.

selftests/tracing: Have trigger-hist-poll.tc use sched_process_exit
Currently trigger-hist-poll.tc uses sched_process_free to test the polling of the histogram file. The way it does that is to run sleep, then execute the poll.c code that polls on the sched_process_free for up to 4 seconds to test that when sleep triggers the sched_process_free trace event, it will update the histogram and wake the poll.c code up. The issue is that sched_process_free trace event is called by delayed_put_task_struct() which is called after a RCU grace period has ended. If CONFIG_RCU_LAZY is enabled, RCU callbacks are batched together and do not execute right away. This causes the delayed_put_task_struct() to be called after the poll.c function finishes and it will report an error that it did not wake up on the event. That's because the event didn't trigger during its wait time. Use sched_process_exit instead, which is called when a process exits and doesn't depend on RCU callbacks that may be delayed.

selftests/ftrace: Fix reading enabled_functions in add_remove_fprobe_module test
The add_remove_fprobe_module test checks the number of functions added to the enabled_functions file to make sure that the functions added or removed is as expected. The issue is that it expects this file to be empty on start up. Now that systemd uses BPF that attaches to functions via ftrace, this file is not empty in several systems: # cat /sys/kernel/tracing/enabled_functions bpf_lsm_file_open (1) R D M tramp: ftrace_regs_caller+0x0/0x61 (call_direct_funcs+0x0/0x50) direct(jmp)-->bpf_trampoline_6442529439+0x0/0xe9 Change the test to read the number of lines in enabled_functions at the start of the test and subtract that from the value of the count for the checks within the test.

KVM: TDX: Reject concurrent change to CPUID entry count
Reject KVM_TDX_INIT_VM if userspace changes cpuid.nent between the
initial read and the subsequent copy of the initialization data.
tdx_td_init() first reads user_data->cpuid.nent to size the flexible
kvm_tdx_init_vm copy. The copied structure also contains cpuid.nent,
and that field can differ from the value used to size the allocation if
userspace modifies the input concurrently. setup_tdparams_cpuids() later
passes init_vm->cpuid.nent to kvm_find_cpuid_entry2(), which uses it as
the array bound for the copied entries.
Require the copied count to match the value used to size the allocation
so that CPUID parsing cannot access beyond the entries actually copied.
