The handle is essential for retrieving the AUX_EVENT of each CPU and is
required in perf mode. It has been added to the coresight_path so that
dependent devices can access it from the path when needed.
The existing bug can be reproduced with:

Correct possible race conditions during device removal.
Previously, a scheduled work item to reset a LUN could still execute
after the device was removed, leading to use-after-free and other
resource access issues.
This race condition occurs because the abort handler may schedule a LUN
reset concurrently with device removal via sdev_destroy(), leading to
use-after-free and improper access to freed resources.
- Check in the device reset handler if the device is still present in
the controller's SCSI device list before running; if not, the reset
is skipped.
- Cancel any pending TMF work that has not started in sdev_destroy().
- Ensure device freeing in sdev_destroy() is done while holding the
LUN reset mutex to avoid races with ongoing resets.

There is one uaf issue in recv_work when running NBD_CLEAR_SOCK and

nbd_open // conf_ref=3

close nbd // conf_ref=1

Or only running NBD_CLEAR_SOCK:

close nbd

Commit 87aac3a80a ("nbd: call nbd_config_put() before notifying the
waiter") moved nbd_config_put() to run before waking up the waiter in
recv_work, in order to ensure that nbd_start_device_ioctl() would not
be woken up while nbd->task_recv was still uncleared.
However, in nbd_start_device_ioctl(), after being woken up it explicitly
calls flush_workqueue() to make sure all current works are finished.
Therefore, there is no need to move the config put ahead of the wakeup.
Move nbd_config_put() to the end of recv_work, so that the reference is
held for the whole lifetime of the worker thread. This makes sure the
config cannot be freed while recv_work is still running, even if clear
+ reconfigure interleave.
In addition, we don't need to worry about recv_work dropping the last
nbd_put (which causes deadlock):

In sync del gendisk path, it deletes gendisk first and the directory
/sys/block/md is removed. Then it releases mddev kobj in a delayed work.
If we enable debug log in sysfs_remove_group, we can see the debug log
'sysfs group bitmap not found for kobject md'. It's the reason that the
parent kobj has been deleted, so it can't find parent directory.
In creating path, it allocs gendisk first, then adds mddev kobj. So it
should delete mddev kobj before deleting gendisk.
Before commit 9e59d60976 ("md: call del_gendisk in control path"), it
releases mddev kobj first. If the kobj hasn't been deleted, it does clean
job and deletes the kobj. Then it calls del_gendisk and releases gendisk
kobj. So it doesn't need to call kobject_del to delete mddev kobj. After
this patch, in sync del gendisk path, the sequence changes. So it needs
to call kobject_del to delete mddev kobj.
After this patch, the sequence is:
1. kobject del mddev kobj
2. del_gendisk deletes gendisk kobj
3. mddev_delayed_delete releases mddev kobj
4. md_kobj_release releases gendisk kobj

[ Upstream commit 7e772a93eb ]
When intel_pmu_drain_pebs_icl() is called to drain PEBS records, the
perf_event_overflow() could be called to process the last PEBS record.
While perf_event_overflow() could trigger the interrupt throttle and
stop all events of the group, like what the below call-chain shows.
perf_event_overflow()
-> __perf_event_overflow()
->__perf_event_account_interrupt()
-> perf_event_throttle_group()
-> perf_event_throttle()
-> event->pmu->stop()
-> x86_pmu_stop()
The side effect of stopping the events is that all corresponding event
pointers in cpuc->events[] array are cleared to NULL.
Assume there are two PEBS events (event a and event b) in a group. When
intel_pmu_drain_pebs_icl() calls perf_event_overflow() to process the
last PEBS record of PEBS event a, interrupt throttle is triggered and
all pointers of event a and event b are cleared to NULL. Then
intel_pmu_drain_pebs_icl() tries to process the last PEBS record of
event b and encounters NULL pointer access.
To avoid this issue, move cpuc->events[] clearing from x86_pmu_stop()
to x86_pmu_del(). It's safe since cpuc->active_mask or
cpuc->pebs_enabled is always checked before access the event pointer
from cpuc->events[].

The Radxa ROCK 5B+/5T USB Type-C port supports Dual Role Data and
should also act as a host. However, currently, when acting as a host,
only self-powered devices work.
Since the ROCK 5B+ supports Dual Role Power, set the power-role
property to "dual" and the try-power-role property to "sink". (along
with related properties)
The ROCK 5T should only support the "source" power-role.
This allows the port to act as a host, supply power to the port, and
allow bus-powered devices to work.
Note that on the ROCK 5T, with this patch applied, it has been
observed that some bus-powered devices do not work correctly. Also,
it has been observed that after connecting a device (and the data-role
switches to host), connecting a host device does not switch the
data-role back to the device role. These issues should be addressed
separately.
Note that there is a separate known issue where USB 3.0 SuperSpeed
devices do not work when oriented in reverse. This issue should also be
addressed separately. (USB 2.0/1.1 devices work in both orientations)

Currently, for beacon_stats, ath12k_mac_get_fw_stats() is called
for each started BSS on the specified hardware.
ath12k_mac_get_fw_stats() will wait for the fw_stats_done completion
after fetching the requested data from firmware. For the beacon_stats,
fw_stats_done completion will be set only when stats are received for
all BSSes. However, for other stats like vdev_stats or pdev_stats, there
is one request to the firmware for all enabled BSSes. Since beacon_stats
is fetched individually for all BSSes enabled in that pdev, waiting for
the completion event results in a timeout error when multiple BSSes are
enabled.
Avoid this by completing the fw_stats_done immediately after
updating the requested BSS's beacon stats in the list. Subsequently,
this list will be used to display the beacon stats for all enabled
BSSes in the requested pdev.
Additionally, remove 'num_bcn_recvd' from the ath12k_fw_stats struct
as it is no longer needed.

[ Upstream commit 8436112341 ]
When transitioning from 5-level to 4-level paging, the existing code
incorrectly accesses page table entries by directly dereferencing CR3 and
applying PAGE_MASK. This approach has several issues:
- __native_read_cr3() returns the raw CR3 register value, which on x86_64
includes not just the physical address but also flags Bits above the
physical address width of the system (i.e. above __PHYSICAL_MASK_SHIFT) are
also not masked.
- The pgd value is masked by PAGE_SIZE which doesn't take into account the
higher bits such as _PAGE_BIT_NOPTISHADOW.
Replace this with proper accessor functions:
- native_read_cr3_pa(): Uses CR3_ADDR_MASK to additionally mask metadata out
of CR3 (like SME or LAM bits). All remaining bits are real address bits or
reserved and must be 0.
- mask pgd value with PTE_PFN_MASK instead of PAGE_MASK, accounting for flags
above bit 51 (_PAGE_BIT_NOPTISHADOW in particular). Bits below 51, but above
the max physical address are reserved and must be 0.

When ETR is enabled as CS_MODE_SYSFS, if the buffer size is changed
and enabled again, currently sysfs_buf will point to the newly
allocated memory(buf_new) and free the old memory(buf_old). But the
etr_buf that is being used by the ETR remains pointed to buf_old, not
updated to buf_new. In this case, it will result in a memory
use-after-free issue.
Fix this by checking ETR's mode before updating and releasing buf_old,
if the mode is CS_MODE_SYSFS, then skip updating and releasing it.

[ Upstream commit 9c95fc710b ]
Without a serial console speed specified in chosen/stdout-path in the
DTB, the serial console uses the default speed of the serial driver,
unless explicitly overridden in a legacy console= kernel command-line
parameter.
After dropping "ti,omap3-uart" from the list of compatible values in DT,
AM33xx serial ports can no longer be used with the legacy OMAP serial
driver, but only with the OMAP-flavored 8250 serial driver (which is
mutually-exclusive with the former). However, replacing
CONFIG_SERIAL_OMAP=y by CONFIG_SERIAL_8250_OMAP=y (with/without enabling
CONFIG_SERIAL_8250_OMAP_TTYO_FIXUP) may not be sufficient to restore
serial console functionality: the legacy OMAP serial driver defaults to
115200 bps, while the 8250 serial driver defaults to 9600 bps, causing
no visible output on the serial console when no appropriate console=
kernel command-line parameter is specified.
Fix this for all AM33xx boards by adding ":115200n8" to
chosen/stdout-path. This requires replacing the "&uartN" reference by
the corresponding "serialN" DT alias.

[ Upstream commit b4e002d8a7 ]
When the CPU that the QSPI interrupt handler runs on (typically CPU 0)
is excessively busy, it can lead to rare cases of the IRQ thread not
running before the transfer timeout is reached.
While handling the timeouts, any pending transfers are cleaned up and
the message that they correspond to is marked as failed, which leaves
the curr_xfer field pointing at stale memory.
To avoid this, clear curr_xfer to NULL upon timeout and check for this
condition when the IRQ thread is finally run.
While at it, also make sure to clear interrupts on failure so that new
interrupts can be run.
A better, more involved, fix would move the interrupt clearing into a
hard IRQ handler. Ideally we would also want to signal that the IRQ
thread no longer needs to be run after the timeout is hit to avoid the
extra check for a valid transfer.

In iommu_mmio_write(), it validates the user-provided offset with the
check: `iommu->dbg_mmio_offset > iommu->mmio_phys_end - 4`.
This assumes a 4-byte access. However, the corresponding
show handler, iommu_mmio_show(), uses readq() to perform an 8-byte
(64-bit) read.
If a user provides an offset equal to `mmio_phys_end - 4`, the check
passes, and will lead to a 4-byte out-of-bounds read.
Fix this by adjusting the boundary check to use sizeof(u64), which
corresponds to the size of the readq() operation.

There is a race between panthor_device_unplug() and

- unplug routine calls drm_dev_unplug()
- panthor_device_suspend() can now execute, and will skip a lot of
important work because the device is currently marked as unplugged.
- IRQs will remain active in this case and IRQ handlers can therefore
try to access a powered down GPU.

little bit earlier, before drm_dev_unplug().

When page cache is used, writebacks are done on a page granularity, and it
is expected that the underlying filesystem (such as v9fs) should respect
the write position. However, currently v9fs will passthrough O_APPEND to
the server even on cached mode. This causes data corruption if a sync or
fstat gets between two writes to the same file.
This patch removes the APPEND flag from the open request we send to the
server when writeback caching is involved. I believe keeping server-side
APPEND is probably fine for uncached mode (even if two fds are opened, one
without O_APPEND and one with it, this should still be fine since they
would use separate fid for the writes).
