The checks for a valid input values are mixed with the logic to insert a
newly allocated nport. Refactor the function so that first the checks
are done.
This allows to untangle the setup steps into a more linear form which
reduces the complexity of the functions.
Also start tracking lport when a lport is assigned to a nport. This
ensures, that the lport is not going away as long it is still referenced
by a nport.

The NVMe PCI transport specification allows for completion queues to be
shared by different submission queues.
This patch allows a submission queue to keep track of the completion queue
it is using with reference counting. As such, it can be ensured that a
completion queue is not deleted while a submission queue is actively
using it.
This patch enables completion queue sharing in the pci-epf target driver.
For fabrics drivers, completion queue sharing is not enabled as it is
not possible as per the fabrics specification. However, this patch
modifies the fabrics drivers to correctly integrate the new API that
supports completion queue sharing.

For the PCI transport, the NVMe specification allows submission queues
to share completion queues, however, this is not supported in the
current NVMe target implementation. This is a preparatory patch to allow
for completion queue (CQ) sharing between different submission queues
(SQ).
To support queue sharing, reference counting completion queues is
required. This patch adds the refcount_t field ref to struct nvmet_cq
coupled with respective nvmet_cq_init(), nvmet_cq_get(), nvmet_cq_put(),
nvmet_cq_is_deletable() and nvmet_cq_destroy() functions.
A CQ reference count is initialized with nvmet_cq_init() when a CQ is
created. Using nvmet_cq_get(), a reference to a CQ is taken when an SQ is
created that uses the respective CQ. Similarly. when an SQ is destroyed,
the reference count to the respective CQ from the SQ being destroyed is
decremented with nvmet_cq_put(). The last reference to a CQ is dropped
on a CQ deletion using nvmet_cq_put(), which invokes nvmet_cq_destroy()
to fully cleanup after the CQ. The helper function nvmet_cq_in_use() is
used to determine if any SQs are still using the CQ pending deletion.
In which case, the CQ must not be deleted. This should protect scenarios
where a bad host may attempt to delete a CQ without first having deleted
SQ(s) using that CQ.
Additionally, this patch adds an array of struct nvmet_cq to the
nvmet_ctrl structure. This allows for the controller to keep track of CQs
as they are created and destroyed, similar to the current tracking done
for SQs. The memory for this array is freed when the controller is freed.
A struct nvmet_ctrl reference is also added to the nvmet_cq structure to
allow for CQs to be removed from the controller whilst keeping the new
API similar to the existing API for SQs.
Sample callchain with CQ refcounting for the PCI endpoint target
(pci-epf):
i. nvmet_execute_create_cq -> nvmet_pci_epf_create_cq
-> nvmet_cq_create -> nvmet_cq_init [cq refcount=1]
ii. nvmet_execute_create_sq -> nvmet_pci_epf_create_sq
-> nvmet_sq_create -> nvmet_sq_init -> nvmet_cq_get [cq refcount=2]
iii. nvmet_execute_delete_sq - > nvmet_pci_epf_delete_sq ->
-> nvmet_sq_destroy -> nvmet_cq_put [cq refcount 1]
iv. nvmet_execute_delete_cq -> nvmet_pci_epf_delete_cq
-> nvmet_cq_put [cq refcount 0]

This patch adds a new helper function nvmet_check_io_cqid(). It is to be
used when parsing host commands for IO CQ creation/deletion and IO SQ
creation to ensure that the specified IO completion queue identifier
(CQID) is not 0 (Admin queue ID). This is a check that already occurs in
the nvmet_execute_x() functions prior to nvmet_check_cqid.
With the addition of this helper function, the CQ ID checks in the
nvmet_execute_x() function can be removed, and instead simply call
nvmet_check_io_cqid() in place of nvmet_check_cqid().

The strncpy() function is deprecated for NUL-terminated strings as
explained in the "strncpy() on NUL-terminated strings" section of
Documentation/process/deprecated.rst.
The key issues are:
- strncpy() fails to guarantee NULL-termination when source > destination
- it unnecessarily zero-pads short strings, causing performance overhead
strscpy() is the proper replacement because:
- it guarantees NULL-termination
- it avoids redundant zero-padding
- it aligns with current kernel string-copying best practice
memcpy() was rejected because:
- NQN buffers (subsysnqn/hostnqn) are treated as NULL-terminated strings:
- strcmp() usage in nvmet_host_allowed() (discovery.c)
- strscpy() to copy subsysnqn in nvmet_execute_disc_identify()
seq_buf wasn't used because:
- this is a simple fixed-size buffer copy
- there is no need for progressive string construction features

Sysfs interface for updating firmware for RMI devices is available even
when F34 probe fails. The code checks for presence of F34 "container"
pointer and then tries to use the function data attached to the
sub-device. F34 assigns the function data early, before it knows if
probe will succeed, leaving behind a stale pointer.
Fix this by expanding checks to not only test for presence of F34
"container" but also check if there is driver data assigned to the
sub-device, and call dev_set_drvdata() only after we are certain that
probe is successful.
This is not a complete fix, since F34 will be freed during firmware
update, so there is still a race when fetching and accessing this
pointer. This race will be addressed in follow-up changes.

idpf_features_check is used to validate the TX packet. skb header
length is compared with the hardware supported value received from
the device control plane. The value is stored in the adapter structure
and to access it, vport pointer is used. During reset all the vports
are released and the vport pointer that the netdev private structure
points to is NULL.
To avoid null-ptr-deref, store the max header length value in netdev
private structure. This also helps to cache the value and avoid
accessing adapter pointer in hot path.

If an aggregate has the following conditions:
- The SRIOV LAG DDP package has been enabled
- The bond is in 802.3ad LACP mode
- The bond is disqualified from supporting SRIOV VF LAG
- Both interfaces were added simultaneously to the bond (same command)
Then there is a chance that the two interfaces will be assigned different
LACP Aggregator ID's. This will cause a failure of the LACP control over
the bond.
To fix this, we can detect if the primary interface for the bond (as
defined by the driver) is not in switchdev mode, and exit the setup flow
if so.
Reproduction steps:
%> ip link add bond0 type bond mode 802.3ad miimon 100
%> ip link set bond0 up
%> ifenslave bond0 eth0 eth1
%> cat /proc/net/bonding/bond0 | grep Agg
Check for Aggregator IDs that differ.

The ice_vc_repr_add_mac() function indicates that it does not store the MAC
address filters in the firmware. However, it still increments vf->num_mac.
This is incorrect, as vf->num_mac should represent the number of MAC
filters currently programmed to firmware.
Indeed, we only perform this increment if the requested filter is a unicast
address that doesn't match the existing vf->hw_lan_addr. In addition,
ice_vc_repr_del_mac() does not decrement the vf->num_mac counter. This
results in the counter becoming out of sync with the actual count.
As it turns out, vf->num_mac is currently only used in legacy made without
port representors. The single place where the value is checked is for
enforcing a filter limit on untrusted VFs.
Upcoming patches to support VF Live Migration will use this value when
determining the size of the TLV for MAC address filters. Fix the
representor mode function to stop incrementing the counter incorrectly.

- Accelerator engine (AE) uncorrectable errors
- Chassis push-pull (CPP) errors
- Host interface (HI) parity errors

Both Intel and AMD CPUs support 5-level paging, which is expected to
become more widely adopted in the future. All major x86 Linux
distributions have the feature enabled.
Remove CONFIG_X86_5LEVEL and related #ifdeffery for it to make it more readable.

Do not recycle the page twice in airoha_qdma_rx_process routine in case
of error. Just run dev_kfree_skb() if the skb has been allocated and marked
for recycling. Run page_pool_put_full_page() directly if the skb has not
been allocated yet.
Moreover, rely on DMA address from queue entry element instead of reading
it from the DMA descriptor for DMA syncing in airoha_qdma_rx_process().

Pull drm fixes from Dave Airlie:
"Weekly drm fixes, I'll be honest and say I think this is larger than
I'd prefer at this point, the main blow out point is that xe has two
larger fixes.
One is a fix for active context utilisation reporting, it's for a
reported regression and will end up in stable anyways, so I don't see
any point in holding it up.
The second is a fix for mixed cpu/gpu atomics, which are currently
broken, but are also not something your average desktop/laptop user is
going to hit in normal operation, and having them fixed now is better
than threading them through stable later.
Other than those, it's mostly the usual, a bunch of amdgpu randoms and
a few other minor fixes.
dma-buf:
- Avoid memory reordering in fence handling
meson:
- Avoid integer overflow in mode-clock calculations
panel-mipi-dbi:
- Fix output with drm_client_setup_with_fourcc()
amdgpu:

- DCN 3.5 fix
- VRR fix
- DP MST fix
- DML 2.1 fixes
- Silence DP AUX spam
- DCN 4.0.1 cursor fix
- VCN 4.0.5 fix
ivpu:
- Fix buffer size in debugfs code
gpuvm:
- Add timeslicing and allocation restriction for SVM

- Fix shrinker debugfs name

Currently, when device mtu is updated, vmxnet3 updates netdev mtu, quiesces
the device and then reactivates it for the ESXi to know about the new mtu.
So, technically the OS stack can start using the new mtu before ESXi knows
about the new mtu.
This can lead to issues for TSO packets which use mss as per the new mtu
configured. This patch fixes this issue by moving the mtu write after
device quiesce.

The debugfs summary output could access uninitialized elements in
the freq_in[] and signal_out[] arrays, causing NULL pointer
dereferences and triggering a kernel Oops (page_fault_oops).
This patch adds u8 fields (nr_freq_in, nr_signal_out) to track the
number of initialized elements, with a maximum of 4 per array.
The summary output functions are updated to respect these limits,
preventing out-of-bounds access and ensuring safe array handling.
Widen the label variables because the change confuses GCC about
max length of the strings.
