The old implementation extracted VLAN TCI info from the payload
before the VLAN tag has been pushed in the payload.
Another problem was that the VLAN TCI was extracted even if the
packet did not have VLAN protocol header.
This resulted in invalid VLAN TCI and as a consequence a random
queue was computed.
This patch fixes the above issues and use the VLAN TCI from the
skb if it is present or VLAN TCI from payload if present. If no
VLAN header is present queue 0 is selected.

If DMA is used, burst length should be set to the bus width of the DMA.
Otherwise, the SPI hardware will transmit/receive one word per DMA
request.
Since this issue affects both transmission and reception, it cannot be
detected with a loopback test.
Replace magic numbers 512 and 0xfff with MX51_ECSPI_CTRL_MAX_BURST.

As &card->tx_queue_lock is acquired under softirq context along the
following call chain from solos_bh(), other acquisition of the same
lock inside process context should disable at least bh to avoid double
lock.
<deadlock #2>
pclose()
--> spin_lock(&card->tx_queue_lock)
<interrupt>
--> solos_bh()
--> fpga_tx()
--> spin_lock(&card->tx_queue_lock)
This flaw was found by an experimental static analysis tool I am
developing for irq-related deadlock.
To prevent the potential deadlock, the patch uses spin_lock_bh()
on &card->tx_queue_lock under process context code consistently to
prevent the possible deadlock scenario.

When the chip is configured to timestamp all receive packets, the
timestamp in the RX completion is only valid if the metadata
present flag is not set for packets received on the wire. In
addition, internal loopback packets will never have a valid timestamp
and the timestamp field will always be zero. We must exclude
any 0 value in the timestamp field because there is no way to
determine if it is a loopback packet or not.
Add a new function bnxt_rx_ts_valid() to check for all timestamp
valid conditions.

The wait_event_interruptible_timeout() function returns 0
if the timeout elapsed, -ERESTARTSYS if it was interrupted
by a signal, and the remaining jiffies otherwise if the
condition evaluated to true before the timeout elapsed.
Driver should have checked for zero return value instead of
a positive value.
MChan: Print a warning for -ERESTARTSYS. The close operation
will proceed anyway when wait_event_interruptible_timeout()
returns for any reason. Since we do the close no matter what,
we should not return this error code to the caller. Change
bnxt_close_nic() to a void function and remove all error
handling from some of the callers.

We are issuing HWRM_FUNC_RESET cmd to reset the device including
all reserved resources, but not clearing the reservations
within the driver struct. As a result, when the driver re-initializes
as part of resume, it believes that there is no need to do any
resource reservation and goes ahead and tries to allocate rings
which will eventually fail beyond a certain number pre-reserved by
the firmware.

The new 6.7-rc1 kernel now checks the checksum on CDAT data. While
using a branch of Fan's DCD qemu work (and specifying DCD devices), the
following splat was observed.
WARNING: CPU: 1 PID: 1384 at drivers/base/devres.c:1064 devm_kfree+0x4f/0x60

The issue in qemu is still unknown but the spat is a straight forward
bug in the CDAT checksum processing code. Use a CDAT buffer variable to
ensure the devm_free() works correctly on error.

In case of a reset triggered by the QCA7000 itself, the behavior of the
qca_spi driver was not quite correct:
- in case of a pending RX frame decoding the drop counter must be
incremented and decoding state machine reseted
- also the reset counter must always be incremented regardless of sync
state

After calling ethtool -g it was not possible to adjust the TX ring
size again:
# ethtool -g eth1
Ring parameters for eth1:
Pre-set maximums:
RX: 4
RX Mini: n/a
RX Jumbo: n/a
TX: 10
Current hardware settings:
RX: 4
RX Mini: n/a
RX Jumbo: n/a
TX: 10
# ethtool -G eth1 tx 8
netlink error: Invalid argument
The reason for this is that the readonly setting rx_pending get
initialized and after that the range check in qcaspi_set_ringparam()
fails regardless of the provided parameter. So fix this by accepting
the exposed RX defaults. Instead of adding another magic number
better use a new define here.

The qca_spi driver stop and restart the SPI kernel thread
(via ndo_stop & ndo_open) in case of TX ring changes. This is
a big issue because it allows userspace to prevent restart of
the SPI kernel thread (via signals). A subsequent change of
TX ring wrongly assume a valid spi_thread pointer which result
in a crash.
So prevent this by stopping the network traffic handling and
temporary park the SPI thread.

In __team_options_register, team_options are allocated and appended to
the team's option_list.
If one option instance allocation fails, the "inst_rollback" cleanup
path frees the previously allocated options but doesn't remove them from
the team's option_list.
This leaves dangling pointers that can be dereferenced later by other
parts of the team driver that iterate over options.
This patch fixes the cleanup path to remove the dangling pointers from
the list.
As far as I can tell, this uaf doesn't have much security implications
since it would be fairly hard to exploit (an attacker would need to make
the allocation of that specific small object fail) but it's still nice
to fix.

The ones that address serious runtime issues are all on the i.MX
platform:
- a boot time panic on imx8qm
- USB hanging under load on imx8
- regressions on the imx93 ethernet phy
Code fixes include a minor error handling for the i.MX PMU driver, and
a number of firmware driver fixes:
- OP-TEE fix for supplicant based device enumeration, and a new sysfs
attribute to needed to fix a race against userspace
- Arm SCMI fix for possible truncation/overflow in the frequency
computations
- Multiple FF-A fixes for the newly added notification support"

This is a partial revert of 8b3517f88ff2 ("PCI: loongson: Prevent LS7A MRRS
increases") for MIPS-based Loongson.
Some MIPS Loongson systems don't support arbitrary Max_Read_Request_Size
(MRRS) settings. 8b3517f88ff2 ("PCI: loongson: Prevent LS7A MRRS
increases") worked around that by (1) assuming that firmware configured
MRRS to the maximum supported value and (2) preventing the PCI core from
increasing MRRS.
Unfortunately, some firmware doesn't set that maximum MRRS correctly, which
results in devices not being initialized correctly. One symptom, from the
Debian report below, is this:
ata4.00: exception Emask 0x0 SAct 0x20000000 SErr 0x0 action 0x6 frozen
ata4.00: failed command: WRITE FPDMA QUEUED
ata4.00: cmd 61/20:e8:00:f0:e1/00:00:00:00:00/40 tag 29 ncq dma 16384 out
res 40/00:00:00:00:00/00:00:00:00:00/00 Emask 0x4 (timeout)
ata4.00: status: { DRDY }
ata4: hard resetting link
Limit MRRS to 256 because MIPS Loongson with higher MRRS support is
considered rare.
This must be done at device enablement stage because the MRRS setting may
get lost if PCI_COMMAND_MASTER on the parent bridge is cleared, and we are
only sure parent bridge is enabled at this point.

Commit 3823119b9c2b ("drm/crtc: Fix uninit-value bug in

num_connectors is only initialized if crtc_req->count_connectors > 0,

The connector_set contains uninitialized values when allocated with
kmalloc_array. However, in the "out" branch, the logic assumes that any
element in connector_set would be equal to NULL if failed to
initialize, which causes the bug reported by Syzbot. The fix is to use
an extra variable to keep track of how many connectors are initialized
indeed, and use that variable to decrease any refcounts in the "out"
branch.

The helper, cxl_dpa_resource_start(), snapshots the dpa-address of an

sufficient to assert that cxl_dpa_rwsem is held rather than acquire it

If a pointer to an uninitialized struct acpi_handle_list is passed to
acpi_evaluate_reference() and it decides to bail out early, either
because acpi_evaluate_object() fails, or because it produces invalid
data, the handles pointer from the struct acpi_handle_list will be
passed to kfree() and if it is not NULL, the kernel will crash on an
attempt to free unallocated memory.
Address this by moving the "end" label in acpi_evaluate_reference() to
the end of the function, which is sufficient, because no cleanup is
needed in that case.

New mddev_resume() calls are added to synchronize IO with array
reconfiguration, however, this introduces a performance regression while
adding it in md_start_sync():
1) someone sets MD_RECOVERY_NEEDED first;
2) daemon thread grabs reconfig_mutex, then clears MD_RECOVERY_NEEDED and
queues a new sync work;
3) daemon thread releases reconfig_mutex;
4) in md_start_sync
a) check that there are spares that can be added/removed, then suspend
the array;
b) remove_and_add_spares may not be called, or called without really
add/remove spares;
c) resume the array, then set MD_RECOVERY_NEEDED again!
Loop between 2 - 4, then mddev_suspend() will be called quite often, for
consequence, normal IO will be quite slow.
Fix this problem by don't set MD_RECOVERY_NEEDED again in md_start_sync(),
hence the loop will be broken.
Fixes: bc08041b32ab ("md: suspend array in md_start_sync() if array need reconfiguration")
