Pull runtime verifier fix from Steven Rostedt:
- Fix multiple definition of __pcpu_unique_da_mon_this
After refactoring monitors, we used static per-cpu variables with the
same names across different per-cpu monitors. This is explicitly
disallowed for modules on some architectures (alpha) or if
CONFIG_DEBUG_FORCE_WEAK_PER_CPU is enabled (e.g. Fedora's debug
kernel). Make sure all those variables have different names to avoid
compilation issues.

This converts some of the visually simpler cases that have been split
over multiple lines. I only did the ones that are easy to verify the
resulting diff by having just that final GFP_KERNEL argument on the next
line.
Somebody should probably do a proper coccinelle script for this, but for
me the trivial script actually resulted in an assertion failure in the
middle of the script. I probably had made it a bit _too_ trivial.
So after fighting that far a while I decided to just do some of the
syntactically simpler cases with variations of the previous 'sed'
scripts.
The more syntactically complex multi-line cases would mostly really want
whitespace cleanup anyway.

This was done entirely with mindless brute force, using
git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'
to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.
Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.
For the same reason the 'flex' versions will be done as a separate
conversion.

Most simple allocations use GFP_KERNEL, and with the new allocation
helpers being introduced, let's just take advantage of that to simplify
that default case.
It's a numbers game:
git grep 'alloc_obj(' |
sed 's/.*\(GFP_[_A-Z]*\).*/\1/' |
sort | uniq -c | sort -n | tail
shows that about 90% of all those new allocator instances just use that
standard GFP_KERNEL.
Those helpers are already macros, and we can easily just make it be the
default case when the gfp argument is missing.
And yes, we could do that for all the legacy interfaces too, but let's
keep it to just the new ones at least for now, since those all got
converted recently anyway, so this is not any "extra" noise outside of
that limited conversion.
And, in fact, I want to do this before doing the -rc1 release, exactly
so that we don't get extra merge conflicts.

Commit 69050f8d6d07 ("treewide: Replace kmalloc with kmalloc_obj for
non-scalar types") started using the new allocation helpers, and in the
process showed that they were completely non-working.
The overflow logic in overflows_flex_counter_type() is completely the
wrong way around, and that broke __alloc_flex() completely. By chance,
the resulting code was then such a mess that clang generated
sufficiently garbage code that objtool warned about it all. Which made
it somewhat quicker to narrow things down.
While fixing overflows_flex_counter_type() would presumably fix this
all, I'm excising the whole broken overflow logic from __alloc_flex(),
because we don't want that kind of code in basic allocation functions
anyway.
That (no longer) broken overflows_flex_counter_type() thing needs to be
inserted into the actual __set_flex_counter() logic in the unlikely case
that we ever want this at all. And made conditional.

This is the result of running the Coccinelle script from
scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to
avoid scalar types (which need careful case-by-case checking), and
instead replace kmalloc-family calls that allocate struct or union
object instances:
Single allocations: kmalloc(sizeof(TYPE), ...)
are replaced with: kmalloc_obj(TYPE, ...)
Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...)
are replaced with: kmalloc_objs(TYPE, COUNT, ...)
Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...)
are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...)
(where TYPE may also be *VAR)
The resulting allocations no longer return "void *", instead returning
"TYPE *".

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull tracing fixes from Steven Rostedt:
- Fix possible dereference of uninitialized pointer
When validating the persistent ring buffer on boot up, if the first
validation fails, a reference to "head_page" is performed in the
error path, but it skips over the initialization of that variable.
Move the initialization before the first validation check.
- Fix use of event length in validation of persistent ring buffer
On boot up, the persistent ring buffer is checked to see if it is
valid by several methods. One being to walk all the events in the
memory location to make sure they are all valid. The length of the
event is used to move to the next event. This length is determined by
the data in the buffer. If that length is corrupted, it could
possibly make the next event to check located at a bad memory
location.
Validate the length field of the event when doing the event walk.
- Fix function graph on archs that do not support use of ftrace_ops
When an architecture defines HAVE_DYNAMIC_FTRACE_WITH_ARGS, it means
that its function graph tracer uses the ftrace_ops of the function
tracer to call its callbacks. This allows a single registered
callback to be called directly instead of checking the callback's
meta data's hash entries against the function being traced.
For architectures that do not support this feature, it must always
call the loop function that tests each registered callback (even if
there's only one). The loop function tests each callback's meta data
against its hash of functions and will call its callback if the
function being traced is in its hash map.
The issue was that there was no check against this and the direct
function was being called even if the architecture didn't support it.
This meant that if function tracing was enabled at the same time as a
callback was registered with the function graph tracer, its callback
would be called for every function that the function tracer also
traced, even if the callback's meta data only wanted to be called
back for a small subset of functions.
Prevent the direct calling for those architectures that do not
support it.
- Fix references to trace_event_file for hist files
The hist files used event_file_data() to get a reference to the
associated trace_event_file the histogram was attached to. This would
return a pointer even if the trace_event_file is about to be freed
(via RCU). Instead it should use the event_file_file() helper that
returns NULL if the trace_event_file is marked to be freed so that no
new references are added to it.
- Wake up hist poll readers when an event is being freed
When polling on a hist file, the task is only awoken when a hist
trigger is triggered. This means that if an event is being freed
while there's a task waiting on its hist file, it will need to wait
until the hist trigger occurs to wake it up and allow the freeing to
happen. Note, the event will not be completely freed until all
references are removed, and a hist poller keeps a reference. But it
should still be woken when the event is being freed.

The refactoring in commit 30984ccf31b7 ("rv: Refactor da_monitor to
minimise macros") replaced per-monitor unique variable names
(da_mon_##name) with a fixed name (da_mon_this).
While this works for 'static' variables (each translation unit gets its
own copy), DEFINE_PER_CPU internally generates a non-static dummy
variable __pcpu_unique_<n> for each per-cpu definition. The requirement
for this variable to be unique although static exists for modules on
specific architectures (alpha) and if the kernel is built with
CONFIG_DEBUG_FORCE_WEAK_PER_CPU (e.g. Fedora's debug kernel).
When multiple per-cpu monitors (e.g. sco and sts) are built-in
simultaneously, they all produce the same __pcpu_unique_da_mon_this
symbol, causing a link error:
ld: kernel/trace/rv/monitors/sts/sts.o: multiple definition of
`__pcpu_unique_da_mon_this';
kernel/trace/rv/monitors/sco/sco.o: first defined here
Fix this by introducing a DA_MON_NAME macro that expands to a
per-monitor unique name (da_mon_<MONITOR_NAME>) via the existing
CONCATENATE helper. This restores the uniqueness that was present
before the refactoring.

The event_hist_poll() function attempts to verify whether an event file is
being removed, but this check may not occur or could be unnecessarily
delayed. This happens because hist_poll_wakeup() is currently invoked only
from event_hist_trigger() when a hist command is triggered. If the event
file is being removed, no associated hist command will be triggered and a
waiter will be woken up only after an unrelated hist command is triggered.
Fix the issue by adding a call to hist_poll_wakeup() in
remove_event_file_dir() after setting the EVENT_FILE_FL_FREED flag. This
ensures that a task polling on a hist file is woken up and receives
EPOLLERR.

The function graph tracer was modified to us the ftrace_ops of the
function tracer. This simplified the code as well as allowed more features
of the function graph tracer.
Not all architectures were converted over as it required the
implementation of HAVE_DYNAMIC_FTRACE_WITH_ARGS to implement. For those
architectures, it still did it the old way where the function graph tracer
handle was called by the function tracer trampoline. The handler then had
to check the hash to see if the registered handlers wanted to be called by
that function or not.
In order to speed up the function graph tracer that used ftrace_ops, if
only one callback was registered with function graph, it would call its
function directly via a static call.
Now, if the architecture does not support the use of using ftrace_ops and
still has the ftrace function trampoline calling the function graph
handler, then by doing a direct call it removes the check against the
handler's hash (list of functions it wants callbacks to), and it may call
that handler for functions that the handler did not request calls for.
On 32bit x86, which does not support the ftrace_ops use with function
graph tracer, it shows the issue:
~# trace-cmd start -p function -l schedule
~# trace-cmd show
# tracer: function_graph
#
# CPU DURATION FUNCTION CALLS
# | | | | | | |
2) * 11898.94 us | schedule();
3) # 1783.041 us | schedule();
1) | schedule() {
------------------------------------------
1) bash-8369 => kworker-7669
------------------------------------------
1) | schedule() {
------------------------------------------
1) kworker-7669 => bash-8369
------------------------------------------
1) + 97.004 us | }
1) | schedule() {
[..]
Now by starting the function tracer is another instance:
~# trace-cmd start -B foo -p function
This causes the function graph tracer to trace all functions (because the
function trace calls the function graph tracer for each on, and the
function graph trace is doing a direct call):
~# trace-cmd show
# tracer: function_graph
#
# CPU DURATION FUNCTION CALLS
# | | | | | | |
1) 1.669 us | } /* preempt_count_sub */
1) + 10.443 us | } /* _raw_spin_unlock_irqrestore */
1) | tick_program_event() {
1) | clockevents_program_event() {
1) 1.044 us | ktime_get();
1) 6.481 us | lapic_next_event();
1) + 10.114 us | }
1) + 11.790 us | }
1) ! 181.223 us | } /* hrtimer_interrupt */
1) ! 184.624 us | } /* __sysvec_apic_timer_interrupt */
1) | irq_exit_rcu() {
1) 0.678 us | preempt_count_sub();
When it should still only be tracing the schedule() function.
To fix this, add a macro FGRAPH_NO_DIRECT to be set to 0 when the
architecture does not support function graph use of ftrace_ops, and set to
1 otherwise. Then use this macro to know to allow function graph tracer to
call the handlers directly or not.

Driver is using num_vhca_ports capability to distinguish between
multiport master device and multiport slave device. num_vhca_ports is a
capability the driver sets according to the MAX num_vhca_ports
capability reported by FW. On the other hand, light SFs doesn't set the
above capbility.
This leads to wrong results whenever light SFs is checking whether he is
a multiport master or slave.
Therefore, use the MAX capability to distinguish between master and
slave devices.

====================
netfilter: updates for net
The following patchset contains Netfilter fixes for *net*:
1) Add missing __rcu annotations to NAT helper hook pointers in Amanda,
FTP, IRC, SNMP and TFTP helpers. From Sun Jian.
2-4):
- Add global spinlock to serialize nft_counter fetch+reset operations.
- Use atomic64_xchg() for nft_quota reset instead of read+subtract pattern.
Note AI review detects a race in this change but it isn't new. The
'racing' bit only exists to prevent constant stream of 'quota expired'
notifications.
- Revert commit_mutex usage in nf_tables reset path, it caused
circular lock dependency. All from Brian Witte.
5) Fix uninitialized l3num value in nf_conntrack_h323 helper.
6) Fix musl libc compatibility in netfilter_bridge.h UAPI header. This
change isn't nice (UAPI headers should not include libc headers), but
as-is musl builds may fail due to redefinition of struct ethhdr.
7) Fix protocol checksum validation in IPVS for IPv6 with extension headers,
from Julian Anastasov.
8) Fix device reference leak in IPVS when netdev goes down. Also from
Julian.
9) Remove WARN_ON_ONCE when accessing forward path array, this can
trigger with sufficiently long forward paths. From Pablo Neira Ayuso.

Query the hypervisor for integrated scheduler support and use it if
configured.
Microsoft Hypervisor originally provided two schedulers: root and core. The
root scheduler allows the root partition to schedule guest vCPUs across
physical cores, supporting both time slicing and CPU affinity (e.g., via
cgroups). In contrast, the core scheduler delegates vCPU-to-physical-core
scheduling entirely to the hypervisor.
Direct virtualization introduces a new privileged guest partition type - L1
Virtual Host (L1VH) — which can create child partitions from its own
resources. These child partitions are effectively siblings, scheduled by
the hypervisor's core scheduler. This prevents the L1VH parent from setting
affinity or time slicing for its own processes or guest VPs. While cgroups,
CFS, and cpuset controllers can still be used, their effectiveness is
unpredictable, as the core scheduler swaps vCPUs according to its own logic
(typically round-robin across all allocated physical CPUs). As a result,
the system may appear to "steal" time from the L1VH and its children.
To address this, Microsoft Hypervisor introduces the integrated scheduler.
This allows an L1VH partition to schedule its own vCPUs and those of its
guests across its "physical" cores, effectively emulating root scheduler
behavior within the L1VH, while retaining core scheduler behavior for the
rest of the system.
The integrated scheduler is controlled by the root partition and gated by
the vmm_enable_integrated_scheduler capability bit. If set, the hypervisor
supports the integrated scheduler. The L1VH partition must then check if it
is enabled by querying the corresponding extended partition property. If
this property is true, the L1VH partition must use the root scheduler
logic; otherwise, it must use the core scheduler. This requirement makes
reading VMM capabilities in L1VH partition a requirement too.

Passing a structure by value into a function is sometimes problematic,
for a number of reasons. Of of these is a warning from the 32-bit arm
compiler:
drivers/gpu/drm/drm_gpusvm.c: In function '__drm_gpusvm_unmap_pages':
drivers/gpu/drm/drm_gpusvm.c:1152:33: note: parameter passing for argument of type 'struct drm_pagemap_addr' changed in GCC 9.1
1152 | dpagemap->ops->device_unmap(dpagemap,
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1153 | dev, *addr);
| ~~~~~~~~~~~
This particular problem is harmless since we are not mixing compiler versions
inside of the compiler. However, passing this by reference avoids the warning
along with providing slightly better calling conventions as it avoids an
extra copy on the stack.

Pull USB / Thunderbolt updates from Greg KH:
"Here is the "big" set of USB and Thunderbolt driver updates for
7.0-rc1. Overall more lines were removed than added, thanks to
dropping the obsolete isp1362 USB host controller driver, always a
nice change.
Other than that, nothing major happening here, highlights are:
- lots of dwc3 driver updates and new hardware support added
- usb gadget function driver updates
- usb phy driver updates
- typec driver updates and additions
- USB rust binding updates for syntax and formatting changes
- more usb serial device ids added
- other smaller USB core and driver updates and additions
All of these have been in linux-next for a long time, with no reported
problems"

Pull tty / serial driver updates from Greg KH:
"Here is the small amount of tty and serial driver updates for 7.0-rc1.
Nothing major in here at all, just some driver updates and minor
tweaks and cleanups including:
- sh-sci serial driver updates
- 8250 driver updates
- attempt to make the tty ports have their own workqueue, but was
reverted after testing found it to have problems on some platforms.
This will probably come back for 7.1 after it has been reworked and
resubmitted
