[ Upstream commit 313ef70a9f ]
Inside print_data_reloc_error(), if extent_from_logical() failed we
return immediately.
However there are the following cases where extent_from_logical() can
return error but still holds a path:
- btrfs_search_slot() returned 0
- No backref item found in extent tree
- No flags_ret provided
This is not possible in this call site though.
So for the above two cases, we can return without releasing the path,
causing extent buffer leaks.

[ Upstream commit 5630f7557d ]
When we are logging a directory and the log context indicates that we
are logging a new name for some other file (that is or was inside that
directory), we skip logging the inodes for new dentries in the directory.
This is ok most of the time, but if after the rename or link operation
that triggered the logging of that directory, we have an explicit fsync
of that directory without the directory inode being evicted and reloaded,
we end up never logging the inodes for the new dentries that we found
during the new name logging, as the next directory fsync will only process
dentries that were added after the last time we logged the directory (we
are doing an incremental directory logging).
So make sure we always log new dentries for a directory even if we are
in a context of logging a new name.
We started skipping logging inodes for new dentries as of commit
c48792c6ee ("btrfs: do not log new dentries when logging that a new name
exists") and it was fine back then, because when logging a directory we
always iterated over all the directory entries (for leaves changed in the
current transaction) so a subsequent fsync would always log anything that
was previously skipped while logging a directory when logging a new name
(with btrfs_log_new_name()). But later support for incrementally logging
a directory was added in commit dc2872247e ("btrfs: keep track of the
last logged keys when logging a directory"), to avoid checking all dir
items every time we log a directory, so the check to skip dentry logging
added in the first commit should have been removed when the incremental
support for logging a directory was added.
A test case for fstests will follow soon.

commit 945865a0dd upstream.
Currently, on ASUS projects, the TAS2781 codec attaches the speaker GPIO
to the first tasdevice_priv instance using devm. This causes
tas2781_read_acpi to fail on subsequent probes since the GPIO is already
managed by the first device. This causes a failure on Xbox Ally X,
because it has two amplifiers, and prevents us from quirking both the
Xbox Ally and Xbox Ally X in the realtek codec driver.
It is unnecessary to attach the GPIO to a device as it is static.
Therefore, instead of attaching it and then reading it when loading the
firmware, read its value directly in tas2781_read_acpi and store it in
the private data structure. Then, make reading the value non-fatal so
that ASUS projects that miss a speaker pin can still work, perhaps using
fallback firmware.

commit 2b7a0f47aa upstream.
The delayed work uec->work is scheduled in gaokun_ucsi_probe()
but never properly canceled in gaokun_ucsi_remove(). This creates
use-after-free scenarios where the ucsi and gaokun_ucsi structure
are freed after ucsi_destroy() completes execution, while the
gaokun_ucsi_register_worker() might be either currently executing
or still pending in the work queue. The already-freed gaokun_ucsi
or ucsi structure may then be accessed.
Furthermore, the race window is 3 seconds, which is sufficiently

commit c69ff68b09 upstream.
As part of the registration of a new 'struct usb_phy' with the USB PHY core
via either usb_add_phy(struct usb_phy *x, ...) or usb_add_phy_dev(struct
usb_phy *x) these functions call list_add_tail(&x->head, phy_list) in
order for the new instance x to be stored in phy_list, a static list
kept internally by the core.
After 7d21114dc6 ("usb: phy: Introduce one extcon device into usb phy")
when executing either of the registration functions above it is possible
that usb_add_extcon() fails, leading to either function returning before
the call to list_add_tail(), leaving x->head uninitialized.
Then, when a driver tries to undo the failed registration by calling
usb_remove_phy(struct usb_phy *x) there will be an unconditional call to
list_del(&x->head) acting on an uninitialized variable, and thus a
possible NULL pointer dereference.
Fix this by initializing x->head before usb_add_extcon() has a
chance to fail. Note that this was not needed before 7d21114dc6 since
list_add_phy() was executed unconditionally and it guaranteed that x->head
was initialized.

Type at byte offset 4:
- Cache error
- TLB Error
- Bus Error
- Micro-architectural Error
All other values are reserved
Yet, there was no information about how this would be encoded.
Spec 2.9A errata corrected it by defining:
- Bit 1 - Cache Error
- Bit 2 - TLB Error
- Bit 3 - Bus Error
- Bit 4 - Micro-architectural Error
All other values are reserved
That actually aligns with the values already defined on older
versions at N.2.4.1. Generic Processor Error Section.
Spec 2.10 also preserve the same encoding as 2.9A.
Adjust CPER and GHES handling code for both generic and ARM

handle_pmi_common() may observe an active bit set in cpuc->active_mask
while the corresponding cpuc->events[] entry has already been cleared,
which leads to a NULL pointer dereference.
This can happen when interrupt throttling stops all events in a group
while PEBS processing is still in progress. perf_event_overflow() can
trigger perf_event_throttle_group(), which stops the group and clears
the cpuc->events[] entry, but the active bit may still be set when
handle_pmi_common() iterates over the events.
The following recent fix:
7e772a93eb ("perf/x86: Fix NULL event access and potential PEBS record loss")
moved the cpuc->events[] clearing from x86_pmu_stop() to x86_pmu_del() and
relied on cpuc->active_mask/pebs_enabled checks. However,
handle_pmi_common() can still encounter a NULL cpuc->events[] entry
despite the active bit being set.
Add an explicit NULL check on the event pointer before using it,
to cover this legitimate scenario and avoid the NULL dereference crash.

[ Upstream commit c94291914b ]
On SMP systems the CPU hotplug callbacks in the "starting" range are
invoked while the CPU is brought up and interrupts are still
disabled. Callbacks which are added later are invoked via the
hotplug-thread on the target CPU and interrupts are explicitly disabled.
In the UP case callbacks which are added later are invoked directly without
the thread indirection. This is in principle okay since there is just one
CPU but those callbacks are invoked with interrupt disabled code. That's
incorrect as those callbacks assume interrupt disabled context.
Disable interrupts before invoking the callbacks on UP if the state is
atomic and interrupts are expected to be disabled. The "save" part is
required because this is also invoked early in the boot process while
interrupts are disabled and must not be enabled prematurely.

[ Upstream commit c418d8b4d7 ]
For events with inherit_stat enabled, a "read" event will be generated
to collect per task event counts on task exit.
The call chain is as follows:
do_exit
-> perf_event_exit_task
-> perf_event_exit_task_context
-> perf_event_exit_event
-> perf_remove_from_context
-> perf_child_detach
-> sync_child_event
-> perf_event_read_event
However, the child event context detaches the task too early in
perf_event_exit_task_context, which causes sync_child_event to never
generate the read event in this case, since child_event->ctx->task is
always set to TASK_TOMBSTONE. Fix that by moving context lock section
backward to ensure ctx->task is not set to TASK_TOMBSTONE before
generating the read event.
Because perf_event_free_task calls perf_event_exit_task_context with
exit = false to tear down all child events from the context, and the
task never lived, accessing the task PID can lead to a use-after-free.
To fix that, let sync_child_event read task from argument and move the
call to the only place it should be triggered to avoid the effect of
setting ctx->task to TASK_TOMESTONE, and add a task parameter to
perf_event_exit_event to trigger the sync_child_event properly when
needed.
This bug can be reproduced by running "perf record -s" and attaching to
any program that generates perf events in its child tasks. If we check
the result with "perf report -T", the last line of the report will leave
an empty table like "# PID TID", which is expected to contain the
per-task event counts by design.

[ Upstream commit ab58153ec6 ]
The delayed work item 'imm_tq' is initialized in imm_attach() and
scheduled via imm_queuecommand() for processing SCSI commands. When the
IMM parallel port SCSI host adapter is detached through imm_detach(),
the imm_struct device instance is deallocated.
However, the delayed work might still be pending or executing
when imm_detach() is called, leading to use-after-free bugs
when the work function imm_interrupt() accesses the already
freed imm_struct memory.
The race condition can occur as follows:
CPU 0(detach thread) | CPU 1
| imm_queuecommand()
| imm_queuecommand_lck()
imm_detach() | schedule_delayed_work()
kfree(dev) //FREE | imm_interrupt()
| dev = container_of(...) //USE
dev-> //USE
Add disable_delayed_work_sync() in imm_detach() to guarantee proper
cancellation of the delayed work item before imm_struct is deallocated.

[ Upstream commit 59e25ef2b4 ]
blk_mq_{add,del}_queue_tag_set() functions add and remove queues from
tagset, the functions make sure that tagset and queues are marked as
shared when two or more queues are attached to the same tagset.
Initially a tagset starts as unshared and when the number of added
queues reaches two, blk_mq_add_queue_tag_set() marks it as shared along
with all the queues attached to it. When the number of attached queues
drops to 1 blk_mq_del_queue_tag_set() need to mark both the tagset and
the remaining queues as unshared.
Both functions need to freeze current queues in tagset before setting on
unsetting BLK_MQ_F_TAG_QUEUE_SHARED flag. While doing so, both functions
hold set->tag_list_lock mutex, which makes sense as we do not want
queues to be added or deleted in the process. This used to work fine
until commit 98d81f0df7 ("nvme: use blk_mq_[un]quiesce_tagset")
made the nvme driver quiesce tagset instead of quiscing individual
queues. blk_mq_quiesce_tagset() does the job and quiesce the queues in
set->tag_list while holding set->tag_list_lock also.
This results in deadlock between two threads with these stacktraces:

The top stacktrace is showing nvme_timeout() called to handle nvme
command timeout. timeout handler is trying to disable the controller and
as a first step, it needs to blk_mq_quiesce_tagset() to tell blk-mq not
to call queue callback handlers. The thread is stuck waiting for
set->tag_list_lock as it tries to walk the queues in set->tag_list.
The lock is held by the second thread in the bottom stack which is
waiting for one of queues to be frozen. The queue usage counter will
drop to zero after nvme_timeout() finishes, and this will not happen
because the thread will wait for this mutex forever.
Given that [un]quiescing queue is an operation that does not need to
sleep, update blk_mq_[un]quiesce_tagset() to use RCU instead of taking
set->tag_list_lock, update blk_mq_{add,del}_queue_tag_set() to use RCU
safe list operations. Also, delete INIT_LIST_HEAD(&q->tag_set_list)
in blk_mq_del_queue_tag_set() because we can not re-initialize it while
the list is being traversed under RCU. The deleted queue will not be
added/deleted to/from a tagset and it will be freed in blk_free_queue()
after the end of RCU grace period.

This commit addresses two issues causing i2c detect to fail.
The identified issues are:
1. Incorrect error handling for BED (Bus Error No ACK/NAK):
Before this commit, Both ALD (Arbitration Loss Detected) and
BED returned -EAGAIN.
2. Missing interrupt status clear after initialization in xfer():
On the K1 SoC, simply fixing the first issue changed the error
from -EAGAIN to -ETIMEOUT. Through tracing, it was determined that
this is likely due to MSD (Master Stop Detected) latency issues.
That means the MSD bit in the ISR may still be set on the next transfer.
As a result, the controller won't work — we can see from the scope that
it doesn't issue any signal.
(This only occurs during rapid consecutive I2C transfers.
That explains why the issue only shows up with i2cdetect.)
With these two fixes, i2c device detection now functions correctly on the K1 SoC.
