ixp4xx_hss_probe() allocates two HDLC netdevs. The first one is stored
in ndev, initialized, and registered with register_hdlc_device(). The
second one is stored in port->netdev and later used by the remove path
for unregister_hdlc_device() and free_netdev().
This means that the registered netdev is not the same object that is
unregistered and freed on remove. It also leaks the first allocation if
the second alloc_hdlcdev() call fails, and the first allocation is not
checked before ndev is used.
Older code allocated the HDLC netdev only once and stored the same object
in both the local variable and port->netdev. The buggy conversion split
this into two alloc_hdlcdev() calls. A later rename changed the local
variable name to ndev, but the underlying mismatch remained.
Fix this by allocating the HDLC netdev only once and assigning the same
object to port->netdev.

airoha_tc_htb_alloc_leaf_queue() assigns queue IDs based on the channel
index (opt->qid = AIROHA_NUM_TX_RING + channel), but updates
real_num_tx_queues with a simple increment (num_tx_queues + 1). When QoS
channels are allocated sparsely (e.g., channels 0 and 3 without 1 and
2), the returned qid can exceed real_num_tx_queues, causing out-of-bounds
accesses in the networking stack.
For example, allocating channel 0 then channel 3 results in
real_num_tx_queues = 34 but qid = 35, which is out of range [0, 34).
Fix this by computing real_num_tx_queues based on the highest active
channel index rather than using a simple counter, in both the allocation
and deletion paths.

task_can_run_on_remote_rq() operates under the assumption that
p->migration_disabled is stable, i.e. if the kernel observed
is_migration_disabled(p) == true, then the BPF scheduler must have also
been able to see this when dispatching the task, and it's the BPF
scheduler's fault that it tried to dispatch a task with migration
disabled to a CPU other than the task's current CPU.
This assumption does not always hold. It's possible that the BPF
scheduler saw is_migration_disabled(p) == false, while the kernel
observes is_migration_disabled(p) == true in dispatch_to_local_dsq()
-> task_can_run_on_remote_rq().
The crucial thing here is that with CONFIG_PREEMPT_RCU, migration is
disabled while a task is executing a BPF program. So, if there's a
situation where the BPF scheduler checks a task while it's not executing
a BPF program, while the kernel checks it while it is executing one,
the BPF scheduler will be killed through no fault of its own.
Consider the following scenario:
1. SCX task @p is executing on CPU A and CPU A gets preempted by a
higher-priority scheduling class. On entry to __schedule(),
p->migration_disabled == 0.
2. In put_prev_task_scx() @p is enqueued on the BPF scheduler's internal
data structures, making it available for other CPUs to dispatch.
3. CPU B enters ops.dispatch(), pops @p from the BPF scheduler's data
structures, checks is_migration_disabled(p) which returns false,
and dispatches @p to CPU B's local DSQ.
4. On CPU A, @p hasn't been switched out yet. Execution reaches
trace_sched_switch() which enters a BPF program, as the BPF scheduler
hooks into the sched_switch tracepoint to detect idle->fair
transitions. On entry into the BPF program, @p disables migration.
5. CPU B enters finish_dispatch() -> dispatch_to_local_dsq() ->
task_can_run_on_remote_rq() which observes
is_migration_disabled(p) == true, triggering scx_error().
This all happens while holding CPU B's rq lock, so it's not
synchronized with @p switching out.
This patch fixes this by moving the call to task_can_run_on_remote_rq()
after @p's rq lock is acquired in dispatch_to_local_dsq(). This way, we
synchronize with @p switching out, since @p holds its rq lock all
the way until it's switched out. Thus, any BPF programs that are called
between put_prev_task_scx() and the end of the context switch are
guaranteed to have finished and cannot influence p->migration_disabled.
Also add a lockdep assertion in task_can_run_on_remote_rq() which
ensures the task rq lock is held if enforce == true.

cifs_setsize() updates the local inode size after SetEOF succeeds. It also
used the new EOF as a local i_blocks estimate, but extending EOF does not
prove that the intervening range was allocated.
For example, after writing 1 MiB and then extending EOF to 10 MiB, the
client can report the file as fully allocated even though the server still
reports a much smaller AllocationSize:
$ dd if=/dev/zero of=test bs=1M count=1
$ truncate -s 10M test && stat -c 'size=%s blocks=%b' test
$ stat --cached=never -c 'size=%s blocks=%b' test
client stat: size=10485760 blocks=20480
server stat: size=10485760 blocks=2056
client stat after revalidation: size=10485760 blocks=2056
A later attribute revalidation may correct i_blocks, but callers such as
xfstests generic/495 invoke swapon immediately after truncate. The swapfile
hole check can therefore observe the inflated local i_blocks value and
accept a sparse file.
Do not grow i_blocks from cifs_setsize() on EOF extension. Only clamp it
on shrink; allocation growth must come from write completion or from
server-reported AllocationSize.
With this change, EOF extension no longer makes a sparse file appear
fully allocated before the next attribute revalidation, and xfstests
generic/495 no longer accepts it through the inflated local i_blocks value.

The RTC represent each weekday with a individual bit set in the WDAY
register, where the 0th bit represent the first day of the week and the
6th bit represents the last day of the week. For each passed day the
chip performs a rotary-left-shift by one to advance the weekday by one.
The tm_wday field represent weekdays by a value in the range of 0-6.
The fls() function return the bit index of the last bit set. To handle
when there are no bits set it will return 0, and if the 0th bit is set
it will return 1, and if the 1st bit is set it will return 2, and so on.
In order to make the result of the fls() function fall into the expected

(which matches how the value is written in ds1307_set_time()).

When a task leaves the BPF scheduler's control, p->scx.dsq_vtime and
p->scx.slice keep whatever values they last held. The slice value is
core-managed and is refilled on the next enqueue, but dsq_vtime is owned
by the BPF scheduler and is never cleared by the core, so a task that
leaves SCX and later returns carries a stale dsq_vtime across the
round-trip.
The stale values are also visible to other SCX schedulers that inspect
the scx fields of non-SCX tasks.
Fix this by resetting both dsq_vtime and slice in scx_disable_task(),
after ops.disable(), so the BPF scheduler can still observe the task's
final values and non-SCX tasks do not retain stale SCX state.

When the RTC is used on systems without a interrupt line, userspace
tools like `hwclock` fall back to a frequent polling loop to synchronize
with the edge of the next second.
On the BQ32000, this aggressive polling can temporarly lock the register
refresh cycle, because the continuous transfers prevent the hardware from
updating the buffer. This results in stale data reads or select() timeouts
in userspace.
This patch introduces a delay before reading the RTC registers in order to
provide a sufficient idle time for the hardware to sync with the register
buffer.

The deprecation notices for direct p->scx.slice/dsq_vtime writes and for
ops->cpu_acquire/release() use plain pr_warn(), so they repeat on every
scheduler (re)load and can flood the kernel log.
The slice/dsq_vtime notice is the worst offender: it is emitted from the
BPF verifier's btf_struct_access callback, which is re-evaluated as the
verifier explores program paths, so a single scheduler load can print it
many times -- hundreds of lines on some hosts, dozens within the same
second.
Switch both notices to pr_warn_ratelimited() so each deprecation is still
reported but bursts no longer spam the log, and add the missing newline
to the slice/dsq_vtime message.

When spi_imx_can_dma() selects DMA, the ECSPI is configured for DMA:
spi_imx_setupxfer() sets CTRL.SMC and clears dynamic_burst, and
spi_imx_dma_transfer() programs the dynamic-burst BURST_LENGTH and the
SDMA watermarks.
If the DMA descriptor cannot be prepared (dmaengine_prep_slave_single()
returns NULL), the transfer is failed with SPI_TRANS_FAIL_NO_START and
falls back to PIO. The dynamic-burst DMA path uses its own bounce
buffers instead of the SPI core's mapping, so xfer->{tx,rx}_sg_mapped
are not set and the core's DMA->PIO retry is skipped; the driver falls
back to PIO internally. But none of the DMA-mode configuration is
undone, so the PIO transfer runs with CTRL.SMC set, the wrong burst
length and dynamic_burst cleared, and the transferred data is corrupted.
This is easily hit on i.MX8MP boards that describe ECSPI DMA in the
device tree but run SDMA on ROM firmware (no external sdma-imx7d.bin):
every ECSPI DMA prepare fails. An Infineon SLB9670 TPM on ECSPI1 then
returns shifted TPM2_GetCapability data, is flagged "field failure
mode", /dev/tpmrm0 is never created.
Set controller->fallback before re-running spi_imx_setupxfer() so the
ECSPI is reconfigured exactly like a normal PIO transfer. With
controller->fallback set, spi_imx_setupxfer() sees spi_imx_can_dma()
return false, so it clears spi_imx->usedma and reprograms the controller
(clears CTRL.SMC, restores dynamic_burst and the PIO burst length). No
explicit spi_imx->usedma = false is needed: setupxfer() already updates
it from the can_dma() result.

smb2_set_sparse() converts every FSCTL_SET_SPARSE failure to false and
marks sparse support as broken for the share. Callers therefore report
EOPNOTSUPP even for errors such as ENOSPC or EACCES, and later sparse
operations remain disabled until the share is unmounted.
Return the SMB2 ioctl error directly. Set broken_sparse_sup only for
EOPNOTSUPP, which indicates that the server does not support the request.

In id_mode_to_cifs_acl(), aclflag was initialized to CIFS_ACL_DACL by default.
This forced the client to request setting the DACL even when only an ownership
(chown) or group (chgrp) change was being performed.
Let build_sec_desc() do the proper flag calculation by initializing aclflag
to 0. build_sec_desc() sets the appropriate bits (CIFS_ACL_OWNER, CIFS_ACL_GROUP,
or CIFS_ACL_DACL) depending on what actually changed. During ownership transfer,
CIFS_ACL_DACL is only set if replace_sids_and_copy_aces() actually replaces the
SIDs inside any of the DACL's ACEs.
If build_sec_desc() results in aclflag being 0 (meaning no changes were mapped),
exit early to avoid sending an empty security descriptor update to the server.

Since commit
f2ba877402 ("arm64: mm: Map the kernel data/bss read-only in the linear map")
the linear alias of the .data and .bss regions is remapped read-only
early during the boot. (Note that a subsequent patch to unmap this
region entirely was reverted just before the v7.2 merge window, and will
be brought back in an improved form for the v7.3 cycle)
Fuad reports that in some cases, the KVM init code may apply relocations
to variables that reside in .data, and does so via the linear map. This
means that remapping .data read-only beforehand is a bad idea, and
results in an early boot crash.
These variables in .data are only present when CONFIG_NVHE_EL2_DEBUG or
CONFIG_NVHE_EL2_TRACING are enabled, which is why it was not spotted in
testing.
So move the remap to mark_rodata_ro(), which is a reasonable place to
put this, and ensures that it happens much later during the boot. It
also means that rodata=off is now taken into account, and so the linear
alias will remain writable in that case.

When function tracing or Kprobes is enabled, entering an ACPI Low
Power Idle (LPI) state triggers the following RCU splat:
RCU not on for: acpi_idle_lpi_enter+0x4/0xd8
WARNING: CPU: 8 PID: 0 at include/linux/trace_recursion.h:162 function_trace_call+0x1e8/0x228
The acpi_idle_lpi_enter() function is invoked within the cpuidle
path after RCU has already been disabled for the current local CPU.
Consequently, ftrace's function_trace_call() expects RCU to be
actively watching before recording trace data, emitting a warning
if it is not.
Fix this by annotating acpi_idle_lpi_enter(), the generic __weak
stub, and the RISC-V implementation of acpi_processor_ffh_lpi_enter()
with __cpuidle. This moves these functions into the '.cpuidle.text'
section, implicitly disabling ftrace instrumentation (notrace) along
this sensitive path and preventing trace-induced RCU warnings during
idle entry.
