amdgpu_acpi_vfct_bios() fetches the VFCT table with acpi_get_table()
but never releases it. acpi_get_table() takes a reference on the
table (incrementing its validation_count and mapping it on the 0->1
transition); without a paired acpi_put_table() the mapping is leaked
on every call, whether or not a matching VBIOS image is found.
Route all exit paths after the table is acquired through a common
acpi_put_table(). The VBIOS image is copied out with kmemdup() before
the table is released, so it remains valid for the caller.

Cc: stable@vger.kernel.org
On systems where PCI bus renumbering occurs (e.g. pci=realloc,
resource conflicts), the runtime bus number may differ from the
BIOS POST bus number recorded in the VFCT table. This causes
amdgpu_acpi_vfct_bios() to fail finding the VBIOS even though
the correct device entry exists.
Introduce amdgpu_acpi_vfct_match() which treats the bus number
as a soft filter: vendor/device/function identity is the hard
requirement, while exact bus match is the preferred path. When
bus numbers disagree but device identity matches, accept the
VFCT entry and log a dev_notice for diagnostics.

amdgpu_bo_create_reserved() only allocates a new BO when
*bo_ptr (struct amdgpu_bo **bo_ptr as input parameter) is
NULL, it simply skips creation when *bo_ptr is non-NULL.
But it unconditionally reserves, pins, gart allocates
and maps the BO afterwards.
When the same non-NULL BO pointer is passed in again,
for example firmware buffers that live in adev and are
re-loaded on every resume / cp_resume / start
under AMDGPU_FW_LOAD_DIRECT, amdgpu_bo_pin() just increases
pin_count unconditionally, however the matching teardown only unpins
once, so pin_count never drops to zero, so TTM is not able
to move, swap or evict a BO, causing BO leaks.
This commit fixes this issue by only pinning the bo
once at creation, and repeated calls no longer
take additional pin references.

pre_reset only force-completes fences of MAPPED queues. A queue in any
other state (e.g. mid-eviction) keeps its last_fence pending; after a
GPU reset that fence never signals, so the eviction/suspend worker and
process teardown (amdgpu_evf_mgr_flush_suspend) wait on it forever and
wedge the machine:

(cherry picked from commit 198663d035cc439eb48844a2da66f6ae1b0de303)
[Why]
FWTS autobrightness fails on eDP panels because actual_brightness can
read higher than the advertised max_brightness (e.g. 63576 vs 62451).
The conversion helpers expose the firmware PWM range to userspace as
[0..max]. But max_brightness is advertised as (max - min), which is
smaller. So reading the level can return a value above max_brightness.
This regressed in commit 4b61b8a390 ("drm/amd/display: Add debugging
message for brightness caps"), which changed max_brightness to
(max - min) and undid commit 8dbd72cb79 ("drm/amd/display: Export full
brightness range to userspace").
[How]
Advertise max_brightness as max, and scale the initial AC/DC brightness
against max too. Update the KUnit expectations to match.

[why]
The 8K120/8K240 timings live in DisplayID extension blocks 2 and 3
of this EDID. The EDID is a 4-block (512-byte) HDMI 2.1 EDID
that uses HF-EEODB.
drm core reads and parses this correctly, but amdgpu rebuilds its own copy.
Only 2 of 4 blocks were copied into sink->dc_edid, that leads to
drm_edid_connector_add_modes() never sees blocks 2 and 3.

Directly populate edid_blob_ptr with a blob whose length is the full,

No functional changes. Just clean up a conceptual mismatch.
Based on feedback on the NUTMEG code in DC, the
preferred_link_setting is meant to force the DP link to a
specific setting, meaning both the link rate and lane count
should be locked to an exact value. What NUTMEG needs is
a lower bound on the link rate, which is not the same concept.
Implement this as a HW workaround flag instead.

The TPM character devices expose a sequential command/response
interface, but their open handlers leave FMODE_PREAD and FMODE_PWRITE
enabled.
After a command leaves a response pending, pread(fd, buf, 16, 0x1400)
passes 0x1400 as *off to tpm_common_read(). The transfer length is
bounded by response_length, but the offset is used unchecked when
forming data_buffer + *off. A sufficiently large offset therefore causes
an out-of-bounds heap read through copy_to_user() and, if the copy
succeeds, an out-of-bounds zero-write through the following memset().
Positional I/O does not provide coherent semantics for this interface.
An arbitrary pread offset cannot represent how much of a response has
been consumed sequentially. The write callback always stores a command
at the start of data_buffer, while pwrite() does not update file->f_pos
and can leave the sequential read cursor stale.
Call nonseekable_open() from both open handlers. This removes
FMODE_PREAD and FMODE_PWRITE, causing positional reads and writes to
fail with -ESPIPE before reaching the TPM callbacks, and explicitly
marks the files non-seekable. Normal read() and write() continue to use
the existing sequential f_pos cursor, leaving the response state machine
unchanged.
Tested on Linux 6.12 with KASAN and a swtpm TPM2 device:
- sequential partial reads returned the complete response
- pread() and preadv() with offset 0x1400 returned -ESPIPE
- pwrite() and pwritev() with offset zero returned -ESPIPE
- the pending response remained intact after the rejected operations
- a subsequent normal command/response cycle completed normally
- no KASAN report was produced.

"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.

m68k: coldfire: fix breakage of missed IO access updates
- 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.

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.

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.

Pre-calculate desc->struct_len up-front in trace_remote_alloc_buffer()
with trace_buffer_desc_size() to fix double-counting.
While at it, use the accessor __first_ring_buffer_desc().

If page allocation fails in trace_remote_alloc_buffer(), desc->nr_cpus
is not yet incremented for the current CPU. As a consequence, on error,
half-allocated rb_desc will not be freed in trace_remote_free_buffer().
Increment desc->nr_cpus as soon as the first allocation for the current
CPU has succeeded.

There were wrong calculations in dm_jiffies_to_msec64 that produced
incorrect output when HZ was different from 1000. This commit fixes them.

There were wrong parentheses when setting stats_aux->merged, so that
merging was never properly accounted. This commit fixes it.

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.
