tracing fix for 7.2:
- Move rb_desc->nr_page_va before updating dynamic array The rb_descr->page_va is a dynamic array counted by nr_page_va. But the updating of the page_va[] is done before the nr_page_va is incremented causing a build with CONFIG_UBSAN_BOUNDS to flag it as an overflow. Move the increment of the counted by value before the array element is updated. - Propagate errors from remote event bulk updates The return value of trace_remote_enable_event() was not being checked by remote_events_dir_enable_write() where it would silently fail. Have it check the return value and propagate that back up to user space. - Fix resource leak on mmiotrace trace_pipe close The mmiotrace tracer was created in 2008 before the trace_pipe had a close callback to allow tracers to do clean up from trace_pipe open. The trace_pipe close cleanup callback was added in 2009 but the mmiotrace tracer was not updated. It had a hack to do the cleanup in the read call, where it may leak if user space did not read the entire buffer. Add a callback to mmiotrace trace_pipe close do to the cleanup properly. - Fix a possible NULL pointer dereference in the mmiotrace tracer If the mmio_pipe_open() fails to find a PCI device, it will set the hiter->dev pointer to NULL. The read function will blindly dereference that pointer. Fix the read call to check to see if that pointer is populated before dereferencing it. - Fix union collision of module and refcnt for dynamic events In 'struct trace_event_call', the 'module' pointer and the 'refcnt' atomic variable share the same memory space in a union. The filter on module logic only checked if the 'module' was set to determine if the event belonged to the module. As dynamic events are always builtin, it doesn't need the 'module' field of the structure and used a refcount. But the module filtering logic would then mistaken these dynamic events as a module and call module_name(event->module) on it. Add a check to see if the event is a dynamic event and if so, do not check it for being part of the given module. - Reset the top level buffer in selftests before running instances The ftracetest selftest initializes each instance before executing the tests. But it does not reset the top level buffer. Dynamic events are only added and removed by the top level so any left over dynamic events will not be removed by the reset in the instances. Left over dynamic events can cause the tests to incorrectly fail. Reset the top level buffer before running the instances. - Make the context_switch counter 64 bit The code to read user space for a system call trace event or for a trace_marker will disable migration, enable preemption, read user space into a per CPU buffer, disable preemption and enable migration again. It checks if the per CPU context switch counter to see if it changed, and if it did not, it would know that the per CPU buffer was not touched by another task. But the save counter was 32 bit and it would compare it to the 64 bit context_switch variable. A long running system could have the context_switch variable greater that 1<<32 in which case the compare will always fail. The compare will promote the 32 bit int saved value to 64 bit and compare it to the full 64 bit counter. Since the top 32 bits of the saved value was zero, it would never match. - Fix a use-after-free of the event_enable trigger The event_enable trigger allows for enabling one event when another event is triggered. When the trigger is removed, it must go through a synchronization phase to make sure it is not triggered again. The trigger itself is delayed by the "bulk delay" logic that was recently added. But the code that frees the event_enable data used to rely on the trigger code to do the synchronization. Now that the code uses the call RCU functions (and a workqueue), that delay no longer is there. Add a callback private_data_free() function that allows triggers to clean up data after the synchronization phase has completed. - Move the module_ref counter into the delay callback Since an event of the event_enable trigger can enable an event for a module, it ups the module ref count for that event's module. This prevents the event from trying to enable an event that no longer exists and cause a use-after-free bug. The ref counter was set back down when the trigger was removed but not after thy synchronization phase. This could lead to the module data being accessed after module was unloaded. Move the module ref decrement into the private_data_free() callback of the event_enable trigger. - Add mutex to protect parser in ftrace filtering The set_ftrace_filter file uses a parsing descriptor that is allocated at open and modified by writes. If multiple threads were to write to the descriptor at the same time, it can corrupt the parser. Add a mutex around the modifications of the parser descriptor. - Fix possible corruption in perf syscall tracing The perf system call trace events can now read user space. To do so, the reads of user space enable preemption and disables it again. During this time that preemption is enabled, the task can migrate. The perf event list head is assigned via a per CPU pointer. It is done before the user space part is called. If the user space reading migrates the task to another CPU, then the head pointer is no longer valid. Re-assign the head pointer after the reading of user space to keep it using the correct data. -----BEGIN PGP SIGNATURE----- iIoEABYKADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCamYDGhQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qkhYAP9G5wDTVQQzitl900iWp9rvQ2Qm5UWN JDnK2HO1elmj0AD8CRiHBI5W3O2yUmoO4bOFZ9YFXz+DqJ1jwkDs5FfqjAU= =EMD9 -----END PGP SIGNATURE----- Merge tag 'trace-v7.2-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing fixes from Steven Rostedt: - Move rb_desc->nr_page_va before updating dynamic array The rb_descr->page_va is a dynamic array counted by nr_page_va.

Rust fixes for v7.2 (2nd)
Toolchain and infrastructure:
- 'zerocopy' crates: update to v0.8.54 to fix a modpost error under
'CONFIG_CC_OPTIMIZE_FOR_SIZE=y'.
There are actually two updates in the PR: the one to v0.8.52 is
fairly large and was originally not intended for a fixes PR, but the
actual fix landed in the v0.8.54 one. Thus I included both here.
The v0.8.52 update includes two things upstream added for us:
'--cfg no_fp_fmt_parse' to avoid a local workaround, and the new
'most_traits' feature.
The good news is that, after these updates, the delta with upstream
is now trivial: only an identifier prefix change and the SPDX
parentheses.
- Fix an objtool warning by adding one more 'noreturn' function for
Rust 1.99.0 (expected 2026-10-01).
- Clean up new 'semicolon_in_expressions_from_macros' lint errors for
Rust 1.99.0 (expected 2026-10-01). The lint can be allowed, but it
will be a hard error at some point in the future anyway, so clean it
up now.
- Locally allow new 'suspicious_runtime_symbol_definitions' lint for
Rust 1.98.0 (expected 2026-08-20).
- Globally allow 'clippy::unwrap_or_default' lint since it relies on
optimizations -- under 'CONFIG_CC_OPTIMIZE_FOR_SIZE=y' it does not
work well.
'kernel' crate:
- 'time' module: fix 'Delta::as_micros_ceil()' to round negative values
correctly.

Pull rust fixes from Miguel Ojeda:
"Toolchain and infrastructure:
- 'zerocopy' crates: update to v0.8.54 to fix a modpost error under
'CONFIG_CC_OPTIMIZE_FOR_SIZE=y'.
There are actually two updates in the PR: the one to v0.8.52 is
fairly large and was originally not intended for a fixes PR, but the
actual fix landed in the v0.8.54 one. Thus I included both here.
The v0.8.52 update includes two things upstream added for us:
'--cfg no_fp_fmt_parse' to avoid a local workaround, and the new
'most_traits' feature.
The good news is that, after these updates, the delta with upstream
is now trivial: only an identifier prefix change and the SPDX
parentheses.
- Fix an objtool warning by adding one more 'noreturn' function for
Rust 1.99.0 (expected 2026-10-01).
- Clean up new 'semicolon_in_expressions_from_macros' lint errors for
Rust 1.99.0 (expected 2026-10-01). The lint can be allowed, but it
will be a hard error at some point in the future anyway, so clean it
up now.
- Locally allow new 'suspicious_runtime_symbol_definitions' lint for
Rust 1.98.0 (expected 2026-08-20).
- Globally allow 'clippy::unwrap_or_default' lint since it relies on
optimizations -- under 'CONFIG_CC_OPTIMIZE_FOR_SIZE=y' it does not
work well.
'kernel' crate:
- 'time' module: fix 'Delta::as_micros_ceil()' to round negative values
correctly"

tracing: perf: Fix stale head for perf syscall tracing
The code that can read the user space parameters of a system call may
enable preemption and migrate. The head of the per CPU perf events list
may be pointing to the wrong CPU event if the code migrates the task.
Reassign the head pointer if the system call event called the code that
may have caused a migration.

ftrace: Add global mutex to serialize trace_parser access
In ftrace, the trace_parser structure is allocated and initialized when a trace file is opened, and is subsequently used across write and release handlers to parse user input. The affected handler paths and their specific functions are: - Open paths: ftrace_regex_open(), ftrace_graph_open() - Write paths: ftrace_regex_write(), ftrace_graph_write() - Release paths: ftrace_regex_release(), ftrace_graph_release() If userspace opens a trace file descriptor and shares it across multiple threads, concurrent write calls will race on the parser's internal state, specifically the 'idx', 'cont', and 'buffer' fields, leading to corrupted input or undefined behavior. Fix this by adding a global mutex, parser_lock, to serialize all access to trace_parser across write and release paths, preventing concurrent corruption of parser state. Fixes: |

tracing: Delay module ref count for "enable_event" trigger
Triggers are now delayed from freeing, but can still be triggered until
after the RCU grace period has ended. The freeing of the enable_event data
is put into the private_data_free() callback, but the put of the module
refcount is done immediately.
It is possible that if a module is removed that has an event that would
enable (or disable) it is still active, it can read the data of the module
after it is removed causing a use-after-free bug.
Move the trace_event_put_ref() that releases the module into the delayed
callback so that the module can not be removed until any reference to its
events are finished.

bpf, sockmap: Fix cork use-after-free in tcp_bpf_sendmsg()
tcp_bpf_sendmsg() keeps msg_tx across sk_stream_wait_memory(), which
drops and reacquires the socket lock. Its error path tries to decide
whether msg_tx names the local temporary message by comparing it with
the current value of psock->cork.
This comparison is unsafe when two threads send on the same socket:
Thread A Thread B
msg_tx = psock->cork
sk_msg_alloc() fails
sk_stream_wait_memory()
releases the socket lock acquires the socket lock
completes the cork
psock->cork = NULL
frees the cork
reacquires the socket lock
msg_tx != psock->cork
sk_msg_free(msg_tx)
The stale cork is therefore mistaken for the local temporary message
and freed again. KASAN reported:
BUG: KASAN: slab-use-after-free in sk_msg_free+0x49/0x50

msg_tx can only name the stack-local tmp or the shared cork. Check for
tmp directly so a changed psock->cork cannot turn a shared message into
an apparent local one.

tracing: Fix context switch counter truncation
trace_user_fault_read() samples nr_context_switches_cpu() before enabling
preemption and retries the user copy if the counter changes. The helper
returns unsigned long long because rq->nr_switches is u64, but the saved
value is unsigned int.
Once a CPU has performed 2^32 context switches, assigning the counter to
cnt discards its upper bits. The comparison after the copy promotes cnt
back to unsigned long long, but the lost bits remain zero, so it reports a
change even when the task was never scheduled out. Every retry then fails
the same way until the 100-try guard warns and the user copy is abandoned.
This affects long-running systems and workloads with high context-switch
rates. A CPU switching 1,000 times per second takes about 50 days.
Store the sampled count in unsigned long long so the full value is
preserved.

selftests/ftrace: Reset triggers at top level before instance loop
When running instance tests, 'ftracetest' creates a new ftrace instance
and runs the tests inside it. Before starting each test, it executes
'initialize_system()' to reset the ftrace state to initial-state.
However, since 'initialize_system()' is executed in the context of the
instance directory, it only cleans up triggers and filters of that
instance.
Any triggers or dynamic events left behind in the top-level instance by
previous failed top-level tests, are left completely untouched. These
top-level leftovers can cause subsequent instance-based tests to fail
or even crash the kernel.
Fix this by executing 'initialize_system()' in the top-level tracing
directory once before entering the instance loop.

tracing: Fix union collision of module and refcnt for dynamic events
In 'struct trace_event_call', the 'module' pointer and the 'refcnt'
atomic variable share the same memory space in a union. For dynamic
events, the union member is 'refcnt', which acts as an active
reference counter.
When a dynamic event (such as kprobe, uprobe, fprobe, eprobe, or
wprobe) has a non-zero reference count (e.g. due to active event
triggers or perf attachments), its 'call->module' evaluates to a
small non-zero integer instead of NULL.
When filtering or setting events for a specific module (e.g., writing
':mod:<module>' to 'set_event'), the code in
'__ftrace_set_clr_event_nolock()' and 'update_event_fields()' reads
'call->module' directly without checking whether the event is dynamic.
This causes the kernel to treat the small integer (refcnt) as a
'struct module' pointer, leading to a NULL/invalid pointer dereference
(Oops) when dereferencing the module name.
Fix this by ensuring that the 'TRACE_EVENT_FL_DYNAMIC' flag is checked
before treating 'call->module' as a valid pointer in these code paths.

drm/amd/display: Fix flip-done timeouts on mode1 reset
The vblank on/off callbacks mixed use of amdgpu_irq_get/put() and amdgpu_dm_crtc_set_vupdate_irq() to enable and disable IRQs. With get/put, base driver will callback into DC to disable IRQs when refcount == 0. With set_vupdate_irq(), DC is called directly to disable IRQs, bypassing base driver's refcount tracking. During gpu reset, base driver can restore IRQs via amdgpu_irq_gpu_reset_resume_helper() > amdgpu_irq_update(). So if get/put() is not used (i.e. refcount == 0), then vupdate_irq will be disabled. This is problematic if DRM requests vblank on before amdgpu_irq_update() is called: drm_vblank_on() > set_vupdate_irq() enables vupdate_irq, but the refcount is still 0. gpu_reset_resume_helper() > irq_update() then immediately disables it, thus leading to flip done timeouts. This is made worse on DCN since VUPDATE_NO_LOCK is the only IRQ enabled. Prior to |

platform/loongarch: laptop: Explicitly reset bl_powered state when suspend
On EAECIS NL60R with EC firmware version 1.11, resuming from S3 has a
very high chance (>90%) of causing the EC to lose the previous backlight
power state. When this happens, the laptop resumes normally from S3, but
the backlight remains off (when shining on the screen with a flash light,
we can see the screen contents are updating normally).
Since there is no generic way to query the EC's backlight state on
Loongson laptop platforms, assume the worst-case scenario and restart
the backlight power inside the kernel each time the system resumes.

platform/loongarch: laptop: Stop setting acpi_device_class()
The driver populates acpi_device_class() which is never read afterward, so make it stop doing that and drop the symbol defined specifically for this purpose. No intentional functional impact. This change will facilitate the removal of "device_class" from "struct acpi_device_pnp" in the future. Reviewed-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: Rafael J.

LoongArch: BPF: Fix memory leak in bpf_jit_free()
When bpf_int_jit_compile() is called for subprograms, it returns early
during the first pass (!prog->is_func || extra_pass is false), keeping
ctx->offset alive for the subsequent extra pass.
If JIT compilation fails for a later subprogram, the BPF core aborts and
calls bpf_jit_free() to clean up the first subprogram. However,
bpf_jit_free() fails to free jit_data->ctx.offset, which causes a memory
leak of the JIT context offsets array.
So fix this by adding the missing kvfree(jit_data->ctx.offset) in
bpf_jit_free().

drm/vc4: Shut down BO cache timer before teardown
The BO cache timer callback schedules time_work, and time_work can rearm
the timer through vc4_bo_cache_free_old().
vc4_bo_cache_destroy() deletes the timer and then cancels the work, which
does not break that cycle: the work being cancelled can rearm the timer,
and the timer then queues work again after teardown.
Use timer_shutdown_sync() instead, so the timer cannot be rearmed and the
cycle ends with cancel_work_sync().

ceph: avoid fs reclaim while using current->journal_info
handle_reply() stores a `ceph_mds_request` pointer in
`current->journal_info` while filling the inode and dentry cache from
an MDS reply.
An allocation in this section can enter direct reclaim and prune
dentries from another filesystem. If this dirties an ext4 inode, ext4
starts a JBD2 transaction. JBD2 interprets the Ceph request in
`current->journal_info` as a journal handle and dereferences the
request's `r_tid` as `h_transaction`, causing a kernel crash, e.g.:
Unable to handle kernel paging request at virtual address 00000000077b4818

ceph: add owner/capability checks for CEPH_IOC_SET_LAYOUT*
These permission checks were already missing in the initial
impementation of these ioctls. This Ceph allows any user who owns a
file descriptor to manipulate the layout of any file, even if they
don't have write permissions.
It might be a good idea to guard other ioctls with permission checks
as well or even disallow regular users (even if they own the file) to
manipulate layout settings completely, as this may be abused to DoS
the Ceph servers, but right now, I find it most urgent to have setter
checks at all.

ceph: fix hanging __ceph_get_caps() with stale mds_wanted
A reader can hang forever in __ceph_get_caps() when the client no
longer holds `FILE_RD`, but local cap state still says that the
capability is already wanted (via `mds_wanted`).
One way to trigger this is through MDS cap revocation. If another
client performs a conflicting operation, the MDS can revoke `FILE_RD`
from the reader; the next read then has to reacquire `FILE_RD`. If
the cap update that should request `FILE_RD` never reaches the MDS
after `cap->mds_wanted` was raised, the reader is left holding only
non-file caps while local `mds_wanted` still includes the file read
caps.
In that state, try_get_cap_refs() sees `need <= mds_wanted` and
returns 0, so __ceph_get_caps() just waits on `i_cap_wq`. If the cap
update that was supposed to request `FILE_RD never reaches the MDS
after `cap->mds_wanted was` raised, no further request is sent and the
waiter can sleep indefinitely until unrelated cap traffic happens to
wake it up.
The ordering issue is that `cap->mds_wanted` is updated in
__prep_cap() before the `CEPH_MSG_CLIENT_CAPS message` is actually
queued for send. That makes one field serve two different meanings at
once: what this client wants, and what the client believes the MDS
already knows it wants.
A proper fix would be to split those states and track whether a cap
update is actually in flight or has been observed by the MDS.
However, simply moving the `cap->mds_wanted assignment` later would
not be sufficient: queueing the message in the messenger does not
guarantee that the MDS processed that specific wanted set, and
reconnect or message loss can still invalidate that assumption.
Fixing that properly would require a larger rework of the cap state
machine.
To allow simpler backports to stable kernels, this patch implements a
simpler workaround:
- stop waiting forever in __ceph_get_caps(); after a bounded wait,
fall back to the renew path
- make ceph_renew_caps() issue a synchronous `OPEN` request whenever
the inode still does not actually hold the wanted caps, instead of
only calling ceph_check_caps()
The extra issued-vs-wanted check in ceph_renew_caps() is necessary
because the previous test only checked whether the inode still had any
real caps at all. That is not enough after revocation: the client can
still hold something like `pLs` and yet be missing `FILE_RD`
completely. In that case, falling back to ceph_check_caps() is not
sufficient, because it still trusts `cap->mds_wanted` and may resend
nothing. By requiring `(issued & wanted) == wanted` before taking the
asynchronous path, the code only uses ceph_check_caps() when the
`wanted caps` are already actually issued. Otherwise, it sends the
synchronous `OPEN` renew.
This preserves the existing asynchronous fast path when the wanted
caps are already issued, avoids changing cap-state semantics, and
fixes the hang by guaranteeing that a stalled waiter eventually
retries through a path that does not rely on the stale `mds_wanted`
state.

rbd: Reset positive result codes to zero in object map update path
In a reply message to an RBD request, a positive result code indicates
a data payload, which is not allowed for writes. While
rbd_osd_req_callback() already resets a positive result code for writes
to zero, rbd_object_map_callback() does not. This allows a corrupted
reply to an object map update to trigger the rbd_assert(*result < 0) in
__rbd_obj_handle_request(). This happens, because
rbd_object_map_callback() calls rbd_obj_handle_request() ->
__rbd_obj_handle_request() and passes this positive result code. From
__rbd_obj_handle_request(), rbd_obj_advance_write() is called, which
leaves the positive result code unchanged and returns true. Therefore,
the if(done && *result) branch is executed in __rbd_obj_handle_request()
and the assertion triggers.
This patch fixes the issue by adjusting the logic in the
rbd_object_map_callback() path. A positive result code for an object map
update is now reset to zero (similar to rbd_osd_req_callback()), and the
message is subsequently handled the same way as if the result code was
zero from the beginning. Additionally, a WARN_ON_ONCE() is added for
this case.
