If, in a previous transfer, the controller sends more data than expected
by the DSPI target, SR.RFDF (RX FIFO is not empty) will remain asserted.
When flushing the FIFOs at the beginning of a new transfer (writing 1
into MCR.CLR_TXF and MCR.CLR_RXF), SR.RFDF should also be cleared.
Otherwise, when running in target mode with DMA, if SR.RFDF remains
asserted, the DMA callback will be fired before the controller sends any
data.
Take this opportunity to reset all Status Register fields.

The XSPI mode implementation in this driver still uses the EOQ flag to
signal the last word in a transmission and deassert the PCS signal.
However, at speeds lower than ~200kHZ, the PCS signal seems to remain
asserted even when SR[EOQF] = 1 indicates the end of a transmission.
This is a problem for target devices which require the deassertation of
the PCS signal between transfers.
Hence, this commit 'forces' the deassertation of the PCS by stopping the
module through MCR[HALT] after completing a new transfer. According to
the reference manual, the module stops or transitions from the Running
state to the Stopped state after the current frame, when any one of the
following conditions exist:
- The value of SR[EOQF] = 1.
- The chip is in Debug mode and the value of MCR[FRZ] = 1.
- The value of MCR[HALT] = 1.
This shouldn't be done if the last transfer in the message has cs_change
set.

Some places in the spi core pass in a const pointer to a device and the
default container_of() casts that away, which is not a good idea.
Preserve the proper const attribute by using container_of_const() for
to_spi_device() instead, which is what it was designed for.
Note, this removes the NULL check for a device pointer in the call, but
no one was ever checking for that return value, and a device pointer
should never be NULL overall anyway, so this should be a safe change.

The current implementation maps the APR table using a fixed size,
which can lead to incorrect mapping when the number of PFs and VFs

After freed the tipc_crypto tx by delete namespace, tipc_aead_encrypt_done

ip netns exec ns1 tipc bearer enable media eth dev veth1
ip netns exec ns1 tipc node set key this_is_a_master_key master
ip netns exec ns1 tipc bearer disable media eth dev veth1
ip netns del ns1
The key of reproduction is that, simd_aead_encrypt is interrupted, leading
to crypto_simd_usable() return false. Thus, the cryptd_queue_worker is
triggered, and the tipc_crypto tx will be visited.

This test reproduces a scenario where HFSC queue length and backlog accounting
can become inconsistent when a peek operation triggers a dequeue and possible
drop before the parent qdisc updates its counters. The test sets up a DRR root
qdisc with an HFSC class, netem, and blackhole children, and uses Scapy to
inject a packet. It helps to verify that HFSC correctly tracks qlen and backlog
even when packets are dropped during peek-induced dequeue.

When enqueuing the first packet to an HFSC class, hfsc_enqueue() calls the
child qdisc's peek() operation before incrementing sch->q.qlen and
sch->qstats.backlog. If the child qdisc uses qdisc_peek_dequeued(), this may
trigger an immediate dequeue and potential packet drop. In such cases,
qdisc_tree_reduce_backlog() is called, but the HFSC qdisc's qlen and backlog
have not yet been updated, leading to inconsistent queue accounting. This
can leave an empty HFSC class in the active list, causing further
consequences like use-after-free.
This patch fixes the bug by moving the increment of sch->q.qlen and
sch->qstats.backlog before the call to the child qdisc's peek() operation.
This ensures that queue length and backlog are always accurate when packet
drops or dequeues are triggered during the peek.

Generally PASID support requires ACS settings that usually create
single device groups, but there are some niche cases where we can get
multi-device groups and still have working PASID support. The primary
issue is that PCI switches are not required to treat PASID tagged TLPs
specially so appropriate ACS settings are required to route all TLPs to
the host bridge if PASID is going to work properly.
pci_enable_pasid() does check that each device that will use PASID has
the proper ACS settings to achieve this routing.
However, no-PASID devices can be combined with PASID capable devices
within the same topology using non-uniform ACS settings. In this case
the no-PASID devices may not have strict route to host ACS flags and
end up being grouped with the PASID devices.
This configuration fails to allow use of the PASID within the iommu
core code which wrongly checks if the no-PASID device supports PASID.
Fix this by ignoring no-PASID devices during the PASID validation. They
will never issue a PASID TLP anyhow so they can be ignored.

If a shorter than assumed transfer was seen, a partial buffer will have
been filled. For that case it isn't sane to attempt to fill more into
the bundle before posting a completion, as that will cause a gap in
the received data.
Check if the iterator has hit zero and only allow to continue a bundle
operation if that is the case.
Also ensure that for putting finished buffers, only the current transfer
is accounted. Otherwise too many buffers may be put for a short transfer.

If the driver reset fails, it may not work properly.

In this patch, the driver calls netif_device_detach()
before the reset and calls netif_device_attach()
after the reset succeeds. If the reset fails,
netif_device_attach() is not called. Therefore,
netdev does not present and cannot be opened.

Commit 4dbd2b2ebe4c ("nvme-multipath: Add visibility for round-robin
io-policy") introduced the creation of the multipath sysfs group under
the NVMe head gendisk device node. However, it also inadvertently added
the same sysfs group under each namespace path device which head node
refers to and that is incorrect.
The multipath sysfs group should only be exposed through the namespace
head gendisk node. This is sufficient, as the head device already
provides symbolic links to the individual namespace paths it manages.
This patch fixes the issue by preventing the creation of the multipath
sysfs group under namespace path devices, ensuring it only appears under
the head disk node.

Commit 5ef44b3cb43b ("xsk: Bring back busy polling support") fixed the
busy polling support in xsk for XDP_ZEROCOPY after it was broken in
commit 86e25f40aa1e ("net: napi: Add napi_config"). The busy polling
support with XDP_COPY remained broken since the napi_id setup in
xsk_rcv_check was removed.
Bring back the setup of napi_id for XDP_COPY so socket level SO_BUSYPOLL
can be used to poll the underlying napi.
Do the setup of napi_id for XDP_COPY in xsk_bind, as it is done
currently for XDP_ZEROCOPY. The setup of napi_id for XDP_COPY in
xsk_bind is safe because xsk_rcv_check checks that the rx queue at which

Allows slcan to receive short messages (typically errors) from the serial
interface.
When error support was added to slcan protocol in
b32ff4668544e1333b694fcc7812b2d7397b4d6a ("can: slcan: extend the protocol
with error info") the minimum valid message size changed from 5 (minimum
standard can frame tIII0) to 3 ("e1a" is a valid protocol message, it is
one of the examples given in the comments for slcan_bump_err() ), but the
check for minimum message length prodicating all decoding was not adjusted.
This makes short error messages discarded and error frames not being
generated.
This patch changes the minimum length to the new minimum (3 characters,
excluding terminator, is now a valid message).

While invalidating, the clearing of the bits in discard_buffer()
is done in one fully ordered CAS operation. In the past this was
done via individual clear_bit(), until e7470ee89f0 (fs: buffer:
do not use unnecessary atomic operations when discarding buffers).
This implies that there were never strong ordering requirements
outside of being serialized by the buffer lock.
As such relax the ordering for archs that can benefit. Further,
the implied ordering in buffer_unlock() makes current cmpxchg
implied barrier redundant due to release semantics. And while in
theory the unlock could be part of the bulk clearing, it is
best to leave it explicit, but without the double barriers.

SGMII_CTRL register, which specifies the active interface, was not
properly restored when resuming from suspend. This led to incorrect
interface selection after resume particularly in scenarios involving
the FPGA.
To fix this:
- Move the SGMII_CTRL setup out of the probe function.
- Initialize the register in the hardware initialization helper function,
which is called during both device initialization and resume.
This ensures the interface configuration is consistently restored after
suspend/resume cycles.

the original code was rtnl_dereference() to indicate that rtnl_lock
was already held. rcu_dereference_protected() is the correct
conversion after replacing rtnl_lock with netdev_lock.
Add a new helper netdev_lock_dereference() similar to

While the MDIO address of the internal PHY on Allwinner sun8i chips is
generally 1, of_mdio_parse_addr is used to cleanly parse the address
from the device-tree instead of hardcoding it.
A commit reworking the code ditched the parsed value and hardcoded the
value 1 instead, which didn't really break anything but is more fragile
and not future-proof.
Restore the initial behavior using the parsed address returned from the
helper.

On Qualcomm platforms if the board uses GPIO hogs msm_pinmux_request()
calls gpiochip_line_is_valid(). After commit 8015443e24e7 ("gpio: Hide
valid_mask from direct assignments") gpiochip_line_is_valid() uses
gc->gpiodev, which is NULL when GPIO hog pins are being processed.
Thus after this commit using GPIO hogs causes the following crash. In
order to fix this, verify that gc->gpiodev is not NULL.
Note: it is not possible to reorder calls (e.g. by calling
msm_gpio_init() before pinctrl registration or by splitting
pinctrl_register() into _and_init() and pinctrl_enable() and calling the
latter function after msm_gpio_init()) because GPIO chip registration
would fail with EPROBE_DEFER if pinctrl is not enabled at the time of
registration.

CONFIG_IO_URING=N, include/linux/io_uring/cmd.h declares the function as

Going bus-off on a channel doing RX could result in dropped packets.
As netif_running() gets cleared before the channel abort procedure,
the handling of any last RDATA packets would see netif_rx() return
non-zero to signal a dropped packet. kvaser_pciefd_read_buffer() dealt
with this "error" by breaking out of processing the remaining DMA RX
buffer.
Only return an error from kvaser_pciefd_read_buffer() due to packet
corruption, otherwise handle it internally.

The functions kvaser_pciefd_start_xmit() and
kvaser_pciefd_handle_ack_packet() raced to stop/wake TX queues and
get/put echo skbs, as kvaser_pciefd_can->echo_lock was only ever taken
when transmitting and KCAN_TX_NR_PACKETS_CURRENT gets decremented
prior to handling of ACKs. E.g., this caused the following error:
can_put_echo_skb: BUG! echo_skb 5 is occupied!
Instead, use the synchronization helpers in netdev_queues.h. As those
piggyback on BQL barriers, start updating in-flight packets and bytes
counts as well.
