ring-buffer fixes for 7.1:
- Fix reporting MISSED EVENTS in trace iterator When the "trace" file is read with tracing enabled, if the writer were to pass the iterator reader, it resets, sets a "missed_events" flag and continues. The tracing output checks for missed events and if there are some, it prints out "[LOST EVENTS]" to let the user know events were dropped. But the clearing of the missed_events happened when the tracing system queried the ring buffer iterator about missed events. This was premature as the ring buffer is per CPU, and the tracing code reads all the CPU buffers and checks for missed events when it is read. If the CPU iterator that had missed events isn't printed next, the output for the LOST EVENTS is lost. Clear the missed_events flag when the iterator moves to the next event and not when the missed_events flag is queried. Also clear it on reset. - Flush and stop the persistent ring buffer on panic On panic the persistent ring buffer is used to debug what caused the panic. But on some architectures, it requires flushing the memory from cache, otherwise, the ring buffer persistent memory may not have the last events and this could also cause the ring buffer to be corrupted on the next boot. - Fix nr_subbufs initialization in simple_ring_buffer_init_mm The remote simple ring buffer meta data nr_subbufs is initialized too early and gets cleared later on, making it zero and not reflect the actual number of sub-buffers. - Fix unload_page for simple_ring_buffer init rollback On error, the pages loaded need to be unloaded. To unload a page it is expected that: page = load_page(va); -> unload_page(page). But the code was doing: unload_page(va) and not unload_page(page). - Create output file from cmd_check_undefined The check for undefined symbols checks if the file *.o.checked exists and if so it skips doing the work. But the *.o.checked file never was created making every build do the work even when it was already done previously. -----BEGIN PGP SIGNATURE----- iIoEABYKADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCag8l7BQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qga3AQDkyh7V4T+fxY5gc5jSKVx5U9bRAMpJ 3GWGNCY9TGUyewEApUNO5MVGvXttyc1ONPHuBcShynj3resJk90sk491kw0= =aY8d -----END PGP SIGNATURE----- Merge tag 'trace-ringbuffer-v7.1-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull ring-buffer fixes from Steven Rostedt: - Fix reporting MISSED EVENTS in trace iterator When the "trace" file is read with tracing enabled, if the writer were to pass the iterator reader, it resets, sets a "missed_events" flag and continues.

soc: fixes for 7.1
The ff-a firmware driver gets 11 individual bugfixes for a number
of issues with robustness to buggy firmware or client implementations.
Another firmware fix address suspend to RAM via PSCI firmware.
The final code change is for the old Arm Integrator reference
platform that recently started exposing an old NULL pointer
dereference bug.
The MAINTAINERS file gets two updates, notably James Tai and Yu-Chun
Lin are stepping up as co-maintainers for the Realtek platform.
The remaining patches are all for devicetree files. Two of these
are for riscv boards, the rest are all for enesas Arm platforms,
addressing build time checking issues as well as minor configuration
problems.

tracing: Fix unload_page for simple_ring_buffer init rollback
The unload_page callback expects the return value of load_page() as its
argument: ret = load_page(va); unload(ret). Fix the rollback code in
simple_ring_buffer_init_mm() where the descriptor's VA is used instead
of the loaded page address.

tracing: Fix nr_subbufs initialization in simple_ring_buffer_init_mm()
nr_subbufs in the ring buffer metadata is always initialized to zero
because it is assigned from cpu_buffer->nr_pages before the page
initialization loop has run. While nr_subbufs is not currently read
by the kernel, it should reflect the actual buffer geometry in the
meta page for correctness.
Move the assignment after the page loop so that cpu_buffer->nr_pages
holds the final count.

ring-buffer: Flush and stop persistent ring buffer on panic
On real hardware, panic and machine reboot may not flush hardware cache
to memory. This means the persistent ring buffer, which relies on a
coherent state of memory, may not have its events written to the buffer
and they may be lost. Moreover, there may be inconsistency with the
counters which are used for validation of the integrity of the
persistent ring buffer which may cause all data to be discarded.
To avoid this issue, stop recording of the ring buffer on panic and
flush the cache of the ring buffer's memory.

ring-buffer: Fix reporting of missed events in iterator
When tracing is active while reading the trace file, if the iterator
reading the buffer detects that the writer has passed the iterator head,
it will reset and set a "missed events" flag. This flag is passed to the
output processing to show the user that events were missed:
CPU:4 [LOST EVENTS]
The problem is that the flag is reset after it is checked in
ring_buffer_iter_dropped(). But the "trace" file iterates over all the CPU
ring buffers and it will check if they are dropped when figuring out which
buffer to print next. This prematurely clears the missed_events flag if
the CPU buffer with the missed events is not the one that is printed next.
On the iteration where the CPU buffer with the missed events is printed,
the check if it had missed events would return false and the output does
not show that events were missed.
Do not reset the missed_events flag when checking if there were missed
events, but instead clear it when moving the iterator head to the next
event.

erofs: fix managed cache race for unaligned extents
After unaligned compressed extents were introduced, the following race
could occur:
[Thread 1] [Thread 2]
(z_erofs_fill_bio_vec)
<handle a Z_EROFS_PREALLOCATED_FOLIO folio>
...
filemap_add_folio (1)
(z_erofs_bind_cache)
<the same folio is found..>
..
..
folio_attach_private (2)
filemap_add_folio (3) again
Since (1) is executed but (2) hasn't been executed yet, it's possible
that another thread finds the same managed folio in z_erofs_bind_cache()
for a different pcluster and calls filemap_add_folio() again since
folio->private is still Z_EROFS_PREALLOCATED_FOLIO.
Fix this by explicitly clearing folio->private before making the folio
visible in the managed cache so that another pcluster can simply wait
on the locked managed folio as what we did for other shared cases [1].
This only impacts unaligned data compression (`-E48bit` with zstd,
for example).

ata fixes for 7.1-rc5
- Make sure that the issuing of a deferred non-NCQ command via
workqueue feature is only used when mixing NCQ and non-NCQ commands
to the same link (i.e. return value ATA_DEFER_LINK), and nothing
else. This way we will not incorrectly try to use the feature for
e.g. PATA drivers.
- The deferred non-NCQ command was stored in a per-port struct.
When using Port Multipliers with FIS-Based Switching, we would thus
needlessly defer commands to all other links. Store the deferred QC
in a per-link struct, such that Port Multipliers with FBS will get
the same performance as before.
- The issuing of a deferred non-NCQ command via workqueue feature
broke support for Port Multipliers using Command-Based Switching.
The issuing of a deferred non-NCQ command via workqueue feature is
not compatible with the use of ap->excl_link, which PMPs with CBS
use for fairness (using implicit round robin).

Description for this pull request:
- Check the index depth limit via ntfs_icx_parent_inc(), avoiding context
corruption from excessively deep child chains.
- Switch security descriptor allocation to kzalloc() to avoid leaking
uninitialized memory.
- Prevent an inconsistent state where vol->volume_label becomes NULL on
allocation failure.
- Validate MFT records by verifying that attrs_offset sits within
bytes_in_use.
- Fix an off-by-one boundary comparison, correctly catching the
out-of-range MFT record number
- Validate the attribute name offset and length bounds prior to AT_UNUSED
enumeration.
- Check for a valid left neighbor before runlist merges to prevent an
8byte out-of-bounds write on crafted volumes.
- Add the missing record comparison against $MFTMirr during mount.
- Fix wrong inode lookup when writing extent MFT records.
- Redirty folio on memory allocation failure in ntfs_write_mft_block().
- Capture and propagate $MFTMirr sync errors during writeback.
- Ensure MFT mirror and synchronous writes wait for I/O completion.
- Fix buffer overflow/heap over-read in ntfs_bdev_write() when cluster
size is smaller than PAGE_SIZE.
- Fix use-after-free in ntfs_inode_sync_filename() when parent index inode
is evicted while still holding its mrec_lock.
- Update resident attribute length validation to match $AttrDef.
- Fix refcount underflow and UAF of the global upcase table.
- Fix two smatch warnings.

kbuild: pacman-pkg: make "rc" releases adhere to pacman versioning scheme
The package versioning scheme does not enable smooth upgrades from "rc"
releases to the corresponding stable releases (e.g. 7.0.0-rc7 -> 7.0.0)
because pacman considers that a downgrade due to the underscore in
pkgver (e.g. 7.0.0_rc7), see e.g. vercmp(8) for an explanation of the
package version comparison used by pacman. Package versions which are
derived from said releases (e.g. built from git revisions) are
similarly affected. Fix this by modifying pkgver in order to remove the
hyphen from kernel versions containing "-rcN", where N is a
non-negative integer.

modpost: prevent stack buffer overflow in do_input_entry() and do_dmi_entry()
Several functions in scripts/mod/file2alias.c build the module alias
string by repeatedly appending into a fixed-size on-stack buffer:
char alias[256] = {};
...
sprintf(alias + strlen(alias), "%X,*", i);
This pattern is unbounded and silently corrupts the stack when the
formatted output exceeds the destination size. Two functions in this
file are realistically reachable with input that overflows their
buffer:
1. do_input_entry() appends across nine bitmap classes
(evbit/keybit/relbit/absbit/mscbit/ledbit/sndbit/ffbit/swbit). The
keybit case alone scans bits from INPUT_DEVICE_ID_KEY_MIN_INTERESTING
(0x71) to INPUT_DEVICE_ID_KEY_MAX (0x2ff), 655 iterations; if a
MODULE_DEVICE_TABLE(input, ...) populates keybit[] densely, the
emission reaches ~3132 bytes — overflowing the 256-byte buffer by
about 12x. include/linux/mod_devicetable.h declares storage for the
full bit range ("keybit[INPUT_DEVICE_ID_KEY_MAX / BITS_PER_LONG + 1]"),
so the worst case is reachable per the ABI.
2. do_dmi_entry() emits one ":<prefix>*<filtered_substr>*" segment per
matched DMI field, up to 4 matches per dmi_system_id. Each substr
is sized as char[79] in struct dmi_strmatch (mod_devicetable.h:584),
and dmi_ascii_filter() copies it verbatim into the alias buffer
without bounds. Worst case: 4 × (1 + 3 + 1 + 79 + 1) = 336 bytes
into alias[256], an 80-byte overflow.
No driver in the current tree triggers either case — every in-tree
INPUT_DEVICE_ID_MATCH_KEYBIT user populates keybit[] very sparsely
(1-3 bits), and no in-tree dmi_system_id has four maximally-long
matches. The concern is defense-in-depth: both unbounded sprintf
chains are silent stack-corruption primitives in a host build tool,
and the buffer sizes have not been revisited since the corresponding
code was first introduced.
The other do_*_entry() handlers in this file (do_usb_entry,
do_cpu_entry, do_typec_entry, ...) were audited and are bounded by
their input field sizes (uint16 IDs, fixed-length keys); their alias
buffers do not need this treatment.
Reproduced under AddressSanitizer with a stand-alone harness mirroring
do_input on a fully-populated keybit:
==18319==ERROR: AddressSanitizer: stack-buffer-overflow
WRITE of size 2 at offset 288 in frame [32, 288) 'alias'
#6 do_input poc.c:44
Stack-canary build:
Abort trap: 6 (strlen(alias)=3134, cap was 256-1)
Add a small alias_append() helper around vsnprintf with a remaining-
space check and call fatal() on overflow, matching the modpost style
for unrecoverable build conditions. do_input() takes the buffer size
as a new parameter; do_input_entry() and do_dmi_entry() pass
sizeof(alias) at every call site. dmi_ascii_filter() takes the
remaining buffer size as well and aborts on truncation. This bounds
every write into the on-stack buffers and turns the latent overflow
into a clean build error if it is ever reached.

srcu: Don't queue workqueue handlers to never-online CPUs
While an srcu_struct structure is in the midst of switching from CPU-0
to all-CPUs state, it can attempt to invoke callbacks for CPUs that
have never been online. Worse yet, it can attempt in invoke callbacks
for CPUs that never will be online, even including imaginary CPUs not in
cpu_possible_mask. This can cause hangs on s390, which is not set up to
deal with workqueue handlers being scheduled on such CPUs. This commit
therefore causes Tree SRCU to refrain from queueing workqueue handlers
on CPUs that have not yet (and might never) come online.
Because callbacks are not invoked on CPUs that have not been
online, it is an error to invoke call_srcu(), synchronize_srcu(), or
synchronize_srcu_expedited() on a CPU that is not yet fully online.
However, it turns out to be less code to redirect the callbacks
from too-early invocations of call_srcu() than to warn about such
invocations. This commit therefore also redirects callbacks queued on
not-yet-fully-online CPUs to the boot CPU.

ata: libata-scsi: do not use the deferred QC feature for ATA_DEFER_PORT
The deferred QC feature was meant to handle mixed NCQ and non-NCQ commands,
i.e. for return value ATA_DEFER_LINK.
ATA_DEFER_PORT is returned by PATA drivers, but also certain SATA drivers
like sata_mv and sata_sil24 that uses ap->excl_link to workaround hardware
bugs in these HBAs. Regardless of the reason, using the deferred QC feature
for ATA_DEFER_PORT is always wrong, and will break the ap->excl_link usage
of the SATA drivers that rely on that feature.
Modify ata_scsi_qc_issue() to only use the deferred QC feature when mixing
NCQ and non-NCQ commands, i.e. ATA_DEFER_LINK.

virt: sev-guest: Do not use host-controlled page order in cleanup path
When issuing an extended guest request (SVM_VMGEXIT_EXT_GUEST_REQUEST),
get_ext_report() allocates a buffer to retrieve a certificate blob from the
host, keeping track of its size in report_req->certs_len.
However, the host may return SNP_GUEST_VMM_ERR_INVALID_LEN, indicating
an invalid buffer size, as well as the expected length of such buffer.
get_ext_report() subsequently updates report_req->certs_len with the
host-controlled value, and cleans up the buffer by computing a page order
from such value. This is incorrect, as the host-provided length may not
match the page order of the original allocation, potentially resulting
in corruption in the page allocator.
Fix this by using alloc_pages_exact() instead, and reusing @npages to
compute the size passed to free_pages_exact(). For consistency, also
use @npages to compute the size when allocating the pages, even though
this last change has no functional effect.

tracing: Fix desc in error path for the trace remote test module
During initialisation in remote_test_load(), if one of the simple_ring_buffer fails to initialise, the error path attempts to rollback initialised buffers. However, the rollback incorrectly uses the global pointer to the trace descriptor, which is only set upon successful load completion. Fix the error path by using the local pointer to the descriptor.

hwmon: (lm90) Add lock protection to lm90_alert
Sashiko reports:
lm90_alert() executes in the smbus alert context and calls
lm90_update_confreg() to disable the hardware alert line, without
acquiring hwmon_lock.
Concurrently, sysfs write operations (such as lm90_write_convrate) hold
the hwmon_lock, temporarily modify data->config, and then restore it.
If an alert interrupt occurs concurrently with a sysfs write, the sysfs
path will overwrite the alert handler's modifications to data->config
and the hardware register.
This unintentionally re-enables the hardware alert line while the alarm is
still active, causing an interrupt storm.
Add the missing lock to lm90_alert() to solve the problem.

hwmon: (lm90) Stop work before releasing hwmon device
Sashiko reports:
In lm90_probe(), the devm action to cancel the alert_work and report_work
(lm90_restore_conf) is registered in lm90_init_client() before
devm_hwmon_device_register_with_info() is called.
Because devm executes cleanup actions in reverse order during module
unbind or probe failure, the hwmon device is unregistered and freed first.
If lm90_alert_work() or lm90_report_alarms() runs in the window between
the hwmon device being freed and the delayed works being cancelled,
lm90_update_alarms() will dereference the freed data->hwmon_dev here.
Fix the problem by canceling the workers separately after registering
the hwmon device and before registering the interrupt handler. This ensures
that the workers are canceled after interrupts are disabled and before
the hwmon device is released. Add "shutdown" flag to indicate that device
shutdown is in progress to prevent workers from being re-armed.
