[ Upstream commit 1cc41b5092 ]
The WCN399x code has two separate cases for loading the NVM data. In
preparation to adding support for WCN3950, which also requires similar
quirk, split the "variant" to be specified explicitly and merge two
snprintfs into a single one.

[ Upstream commit 366ceff495 ]
'hci_register_dev()' calls power up function, which is executed by
kworker - 'hci_power_on()'. This function does access to bluetooth chip
using callbacks from 'hci_ldisc.c', for example 'hci_uart_send_frame()'.
Now 'hci_uart_send_frame()' checks 'HCI_UART_PROTO_READY' bit set, and
if not - it fails. Problem is that 'HCI_UART_PROTO_READY' is set after
'hci_register_dev()', and there is tiny chance that 'hci_power_on()' will
be executed before setting this bit. In that case HCI init logic fails.
Patch moves setting of 'HCI_UART_PROTO_READY' before calling function
'hci_uart_register_dev()'.

When __ftrace_event_enable_disable invokes the class callback to
unregister the event, the return value is not reported up to the
caller, hence leading to event unregister failures being silently
ignored.
This patch assigns the ret variable to the invocation of the
event unregister callback, so that its return value is stored
and reported to the caller, and it raises a warning in case
of error.

Device setup:
netdevsim0 (down)
^ ^
bond netdevsim1.100@netdevsim1 allmulticast=on (down)
When we enslave the lower device (netdevsim0) which has a vlan, we
propagate vlan's allmuti/promisc flags during ndo_open. This causes
(re)locking on of the real_dev.
Propagate allmulti/promisc on flags change, not on the open. There
is a slight semantics change that vlans that are down now propagate
the flags, but this seems unlikely to result in the real issues.
Reproducer:
echo 0 1 > /sys/bus/netdevsim/new_device
dev_path=$(ls -d /sys/bus/netdevsim/devices/netdevsim0/net/*)
dev=$(echo $dev_path | rev | cut -d/ -f1 | rev)

As far as I can tell, these calls of list_del_init() on bg_list cannot
run concurrently with btrfs_mark_bg_unused() or btrfs_mark_bg_to_reclaim(),
as they are in transaction error paths and situations where the block
group is readonly.
However, if there is any chance at all of racing with mark_bg_unused(),
or a different future user of bg_list, better to be safe than sorry.
Otherwise we risk the following interleaving (bg_list refcount in parens)
T1 (some random op) T2 (btrfs_mark_bg_unused)
!list_empty(&bg->bg_list); (1)
list_del_init(&bg->bg_list); (1)
list_move_tail (1)
btrfs_put_block_group (0)
btrfs_delete_unused_bgs
bg = list_first_entry
list_del_init(&bg->bg_list);
btrfs_put_block_group(bg); (-1)
Ultimately, this results in a broken ref count that hits zero one deref
early and the real final deref underflows the refcount, resulting in a WARNING.

We use CD/DVD drives under Marvell 88SE9215 SATA controller on many
Loongson-based machines. We found its PIO doesn't work well, and on the
opposite its DMA seems work very well.
We don't know the detail of the 88SE9215 SATA controller, but we have
tested different CD/DVD drives and they all have problems under 88SE9215
(but they all work well under an Intel SATA controller). So, we consider
this problem is bound to 88SE9215 SATA controller rather than bound to
CD/DVD drives.
As a solution, we define a new dedicated AHCI board id which is named
board_ahci_yes_fbs_atapi_dma for 88SE9215, and for this id we set the
AHCI_HFLAG_ATAPI_DMA_QUIRK and ATA_QUIRK_ATAPI_MOD16_DMA flags on the
SATA controller in order to prefer ATAPI DMA.

Lenovo ThinkPad Hybrid USB-C with USB-A Dock (17ef:a359) is affected by
the same problem as the Lenovo Powered USB-C Travel Hub (17ef:721e):
Both are based on the Realtek RTL8153B chip used to use the cdc_ether
driver. However, using this driver, with the system suspended the device
constantly sends pause-frames as soon as the receive buffer fills up.
This causes issues with other devices, where some Ethernet switches stop
forwarding packets altogether.
Using the Realtek driver (r8152) fixes this issue. Pause frames are no
longer sent while the host system is suspended.

In f2fs_truncate_inode_blocks(), UBSAN detects that get_nid() tries to
access .i_nid[-924], it means both offset[0] and level should zero.
The possible case should be in f2fs_do_truncate_blocks(), we try to
truncate inode size to zero, however, dn.ofs_in_node is zero and
dn.node_page is not an inode page, so it fails to truncate inode page,
and then pass zeroed free_from to f2fs_truncate_inode_blocks(), result
in this issue.
if (dn.ofs_in_node || IS_INODE(dn.node_page)) {
f2fs_truncate_data_blocks_range(&dn, count);
free_from += count;
}
I guess the reason why dn.node_page is not an inode page could be: there
are multiple nat entries share the same node block address, once the node
block address was reused, f2fs_get_node_page() may load a non-inode block.
Let's add a sanity check for such condition to avoid out-of-bounds access
issue.

syzbot report a deadlock in diFree. [1]
When calling "ioctl$LOOP_SET_STATUS64", the offset value passed in is 4,
which does not match the mounted loop device, causing the mapping of the
mounted loop device to be invalidated.
When creating the directory and creating the inode of iag in diReadSpecial(),
read the page of fixed disk inode (AIT) in raw mode in read_metapage(), the
metapage data it returns is corrupted, which causes the nlink value of 0 to be
assigned to the iag inode when executing copy_from_dinode(), which ultimately
causes a deadlock when entering diFree().
To avoid this, first check the nlink value of dinode before setting iag inode.

[ Upstream commit 7fcbf78962 ]
The JFS filesystem calculates allocation group (AG) size using 1 <<
l2agsize in dbExtendFS(). When l2agsize exceeds 31 (possible with >2TB
aggregates on 32-bit systems), this 32-bit shift operation causes undefined
behavior and improper AG sizing.
On 32-bit architectures:
- Left-shifting 1 by 32+ bits results in 0 due to integer overflow
- This creates invalid AG sizes (0 or garbage values) in
sbi->bmap->db_agsize
- Subsequent block allocations would reference invalid AG structures
- Could lead to:
- Filesystem corruption during extend operations
- Kernel crashes due to invalid memory accesses
- Security vulnerabilities via malformed on-disk structures
Fix by casting to s64 before shifting:
bmp->db_agsize = (s64)1 << l2agsize;
This ensures 64-bit arithmetic even on 32-bit architectures. The cast
matches the data type of db_agsize (s64) and follows similar patterns in
JFS block calculation code.

[ Upstream commit 70ca3246ad ]
The expression "inactags << bmp->db_agl2size" in the function
dbFinalizeBmap() is computed using int operands. Although the
values (inactags and db_agl2size) are derived from filesystem
parameters and are usually small, there is a theoretical risk that
the shift could overflow a 32-bit int if extreme values occur.
According to the C standard, shifting a signed 32-bit int can lead
to undefined behavior if the result exceeds its range. In our
case, an overflow could miscalculate free blocks, potentially
leading to erroneous filesystem accounting.
To ensure the arithmetic is performed in 64-bit space, we cast
"inactags" to s64 before shifting. This defensive fix prevents any
risk of overflow and complies with kernel coding best practices.

Add device type data for S32G2/S32G3 SoC.
FlexCAN module from S32G2/S32G3 is similar with i.MX SoCs, but interrupt
management is different.
On S32G2/S32G3 SoC, there are separate interrupts for state change, bus
errors, Mailboxes 0-7 and Mailboxes 8-127 respectively.
In order to handle this FlexCAN hardware particularity, first reuse the
'FLEXCAN_QUIRK_NR_IRQ_3' quirk provided by mcf5441x's irq handling
support. Secondly, use the newly introduced
'FLEXCAN_QUIRK_SECONDARY_MB_IRQ' quirk which handles the case where two
separate mailbox ranges are controlled by independent hardware interrupt
lines.

We noticed the kworker in page_pool_release_retry() was waken
up repeatedly and infinitely in production because of the
buggy driver causing the inflight less than 0 and warning
us in page_pool_inflight()[1].
Since the inflight value goes negative, it means we should

the kworker when detecting the inflight negative in

When the task management thread processes reply queues while the reset
thread resets them, the task management thread accesses an invalid queue ID
(0xFFFF), set by the reset thread, which points to unallocated memory,
causing a crash.
Add flag 'io_admin_reset_sync' to synchronize access between the reset,
I/O, and admin threads. Before a reset, the reset handler sets this flag to
block I/O and admin processing threads. If any thread bypasses the initial
check, the reset thread waits up to 10 seconds for processing to finish. If
the wait exceeds 10 seconds, the controller is marked as unrecoverable.

Commit ae1f3db006 ("ata: ahci: do not enable LPM on external ports")
changed so that LPM is not enabled on external ports (hotplug-capable or
eSATA ports).
This is because hotplug and LPM are mutually exclusive, see 7.3.1 Hot Plug
Removal Detection and Power Management Interaction in AHCI 1.3.1.
This does require that firmware has set the appropate bits (HPCP or ESP)
in PxCMD (which is a per port register in the AHCI controller).
If the firmware has failed to mark a port as hotplug-capable or eSATA in
PxCMD, then there is currently not much a user can do.
If LPM is enabled on the port, hotplug insertions and removals will not be
detected on that port.
In order to allow a user to fix up broken firmware, add 'external' to the
libata.force kernel parameter.
libata.force can be specified either on the kernel command line, or as a
kernel module parameter.

Currently, ath12k_dp_mon_srng_process uses ath12k_hal_srng_src_get_next_entry
to fetch the next entry from the destination ring. This is incorrect because
ath12k_hal_srng_src_get_next_entry is intended for source rings, not destination
rings. This leads to invalid entry fetches, causing potential data corruption or
crashes due to accessing incorrect memory locations. This happens because the
source ring and destination ring have different handling mechanisms and using
the wrong function results in incorrect pointer arithmetic and ring management.
To fix this issue, replace the call to ath12k_hal_srng_src_get_next_entry with
ath12k_hal_srng_dst_get_next_entry in ath12k_dp_mon_srng_process. This ensures
that the correct function is used for fetching entries from the destination
ring, preventing invalid memory accesses.

ATH11K_FLAG_QMI_FAIL bit is set. So call ath11k_fw_destroy() to

[ Upstream commit 1bcd209818 ]
Currently, the driver allocates cacheable DMA buffers for rings like
HAL_REO_DST and HAL_WBM2SW_RELEASE. The buffers for HAL_WBM2SW_RELEASE
are large (1024 KiB), exceeding the SWIOTLB slot size of 256 KiB. This
leads to "swiotlb buffer is full" error messages on systems without an
IOMMU that use SWIOTLB, causing driver initialization failures. The driver
calls dma_map_single() with these large buffers obtained from kzalloc(),
resulting in ring initialization errors on systems without an IOMMU that
use SWIOTLB.
To address these issues, replace the flawed buffer allocation mechanism
with the appropriate DMA API. Specifically, use dma_alloc_noncoherent()
for cacheable DMA buffers, ensuring proper freeing of buffers with
dma_free_noncoherent().
Error log:
[ 10.194343] ath11k_pci 0000:04:00.0: swiotlb buffer is full (sz:1048583 bytes), total 32768 (slots), used 2529 (slots)

There is a possibility of getting page fault if the overall
buffer size is not aligned to 256bytes. Since MFC does read
operation only and it won't corrupt the data values even if
it reads the extra bytes.
Corrected luma and chroma plane sizes for V4L2_PIX_FMT_NV12M
and V4L2_PIX_FMT_NV21M pixel format.
