serdev: Convert to_serdev_*() helpers to macros and use container_of_const()
If these helpers receive the 'const struct device' pointer, then the const qualifier will get dropped, leading to below warning: warning: passing argument 1 of ‘to_serdev_device_driver’ discards 'const' qualifier from pointer target type [-Wdiscarded-qualifiers] This is not an issue as of now, but with the future commits adding serdev device based driver matching, this warning will get triggered. Hence, convert these helpers to macros so that the qualifier get preserved and also use container_of_const() as container_of() is deprecated.

Convert more 'alloc_obj' cases to default GFP_KERNEL arguments
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. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |

Convert 'alloc_obj' family to use the new default GFP_KERNEL argument
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.

add default_gfp() helper macro and use it in the new *alloc_obj() helpers
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.

treewide: Replace kmalloc with kmalloc_obj for non-scalar types
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 *". Signed-off-by: Kees Cook <kees@kernel.org> |

Tracing fixes for 7.0:
- 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. -----BEGIN PGP SIGNATURE----- iIoEABYKADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCaZd4ExQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qqX5AP4powfnNnRfLSKH9idhTp+ltmJ+9roy L7kWTr/z20S2VQEAk331PNZ32uZu+/ZUETYpgtEx4SbRGZFehTBv1ddjfw4= =TWj5 -----END PGP SIGNATURE----- Merge tag 'trace-v7.0-2' of 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.

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. * tag 'trace-v7.0-2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: tracing: Wake up poll waiters for hist files when removing an event tracing: Fix checking of freed trace_event_file for hist files fgraph: Do not call handlers direct when not using ftrace_ops tracing: ring-buffer: Fix to check event length before using ring-buffer: Fix possible dereference of uninitialized pointer |

tracing: Wake up poll waiters for hist files when removing an event
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.

fgraph: Do not call handlers direct when not using ftrace_ops
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.

net/mlx5: Fix multiport device check over light SFs
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.

inet: move icmp_global_{credit,stamp} to a separate cache line
icmp_global_credit was meant to be changed ~1000 times per second,
but if an admin sets net.ipv4.icmp_msgs_per_sec to a very high value,
icmp_global_credit changes can inflict false sharing to surrounding
fields that are read mostly.
Move icmp_global_credit and icmp_global_stamp to a separate
cacheline aligned group.

mshv: Add support for integrated scheduler
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.

capping driver when called from the PMU subsystem and make it add all
package CPUs to the PMU cpumask to allow tools to read RAPL events
from any CPU in the package (Kuppuswamy Satharayananyan)

driver to account for the fact that on partitioned systems, multiple
TPMI instances may exist per package, but RAPL registers are only
valid on one instance (Kuppuswamy Satharayananyan)
- Describe the new intel_idle.table command line option in the
admin-guide intel_idle documentation (Artem Bityutskiy)
- Fix a crash in the ladder cpuidle governor on systems with only one
(polling) idle state available by making the cpuidle core bypass the
governor in those cases and adjust the other existing governors to
that change (Aboorva Devarajan, Christian Loehle)
- Update kerneldoc comments for wake IRQ management functions that
have not been matching the code (Wang Jiayue)

fsverity: fix build error by adding fsverity_readahead() stub
hppa-linux-gcc 9.5.0 generates a call to fsverity_readahead() in
f2fs_readahead() when CONFIG_FS_VERITY=n, because it fails to do the
expected dead code elimination based on vi always being NULL. Fix the
build error by adding an inline stub for fsverity_readahead(). Since
it's just for opportunistic readahead, just make it a no-op.

drm/pagemap: pass pagemap_addr by reference
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.

USB / Thunderbolt changes for 7.0-rc1
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.

TTY / Serial driver updates for 7.0-rc1
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
- other tiny tty driver changes
All of these have been in linux-next for a while with no reported
problems.

Char/Misc/IIO driver changes for 7.0-rc1
Here is the big set of char/misc/iio and other smaller driver subsystem changes for 7.0-rc1. Lots of little things in here, including: - Loads of iio driver changes and updates and additions - gpib driver updates - interconnect driver updates - i3c driver updates - hwtracing (coresight and intel) driver updates - deletion of the obsolete mwave driver - binder driver updates (rust and c versions) - mhi driver updates (causing a merge conflict, see below) - mei driver updates - fsi driver updates - eeprom driver updates - lots of other small char and misc driver updates and cleanups All of these have been in linux-next for a while, with no reported issues except for a merge conflict with your tree due to the mhi driver changes in the drivers/net/wireless/ath/ath12k/mhi.c file.
