There are few use cases where CQ create and destroy
is seen before re-creating the CQ, this kind of use
case is disturbing the RR distribution and all the
active CQ getting mapped to only 2 NQ alternatively.
Fixing the CQ to NQ hash calculation by implementing
a quick load sorting mechanism under a mutex.
Using this, if the CQ was allocated and destroyed
before using it, the nq selecting algorithm still
obtains the least loaded CQ. Thus balancing the load
on NQs.

Move NQ related data structures from rdev to a new structure
named "struct bnxt_re_nq_record" by keeping a pointer to in
the rdev structure. Allocate the memory for it dynamically.
This change is needed for subsequent patches in the series.
Also, removed the nq_task variable from rdev structure as it
is redundant and no longer used.
This change would help to reduce the size of the driver private
structure as well.

L2 driver allocates and populates the MSI-x vector details for RoCE
in the en_dev structure. RoCE driver requires minimum 2 MSIx vectors.
Hence during probe, driver has to check and bail out if there are not
enough MSI-x vectors reserved for it before proceeding further
initialization.

Add support for the 'ethtool -d <dev>' command to retrieve and print
a register dump for fbnic. The dump defaults to version 1 and consists
of two parts: all the register sections that can be dumped linearly, and
an RPC RAM section that is structured in an interleaved fashion and
requires special handling. For each register section, the dump also
contains the start and end boundary information which can simplify parsing.

The pointer list->list is dereferenced before the NULL check.
Fix this by moving the NULL check outside the for loop, so that
the check is performed before the dereferencing.
The list->list pointer cannot be NULL so this has no effect on runtime.
It's just a correctness issue.
This issue was reported by Coverity Scan.

Usage of the telem sysfs file allows for partial reads at an offset.
The current callback method returns the buffer starting from offset 0
only.
Include the requested offset in the callback and update the necessary
address calculations with the offset.
Note: offset addition is moved from the caller to the local usage. For
non-callback usage this is unchanged behavior.

When tb[IPSET_ATTR_IP_TO] is not present but tb[IPSET_ATTR_CIDR] exists,
the values of ip and ip_to are slightly swapped. Therefore, the range check
for ip should be done later, but this part is missing and it seems that the
vulnerability occurs.
So we should add missing range checks and remove unnecessary range checks.

Move the timeout/expire/flag members from nft_trans_one_elem struct into
a dybamically allocated structure, only needed when timeout update was
requested.
This halves size of nft_trans_one_elem struct and allows to compact up to
124 elements in one transaction container rather than 62.
This halves memory requirements for a large flush or insert transaction,
where ->update remains NULL.
Care has to be taken to release the extra data in all spots, including
abort path.

Commit 18011eac28c7 ("arm64: tls: Avoid unconditional zeroing of
tpidrro_el0 for native tasks") tried to optimise the context switching
of tpidrro_el0 by eliding the clearing of the register when switching
to a native task with kpti enabled, on the erroneous assumption that
the kpti trampoline entry code would already have taken care of the
write.
Although the kpti trampoline does zero the register on entry from a
native task, the check in tls_thread_switch() is on the *next* task and
so we can end up leaving a stale, non-zero value in the register if the
previous task was 32-bit.
Drop the broken optimisation and zero tpidrro_el0 unconditionally when
switching to a native 64-bit task.

Merge series from Jonas Rebmann <jre@pengutronix.de>:
The i.MX SPI controller supports inserting a configurable delay between
subsequent words, which is needed for some slower devices that couldn't
keep up otherwise.
This patch series introduces support for the word delay parameters for
i.MX51 onwards.
The SPI clock (CSRC=0) was chosen as the clock source over the also
available 32.768 KHz Low-Frequency Reference Clock (CSRC=1). The sample
period control bits (SAMPLE_PERIOD) are set to the selected word delay
converted to SPI clock cycles. A deviation from the requested number of
wait cycles and the actual word delay was observed via both software
timings and oscilloscope measurements and accounted for.
The Chip Select Delay Control bits in the Sample Period Control Register
remain zero.
Behaviour on i.MX35 and earlier, where the CSPI interface is used,
remains unchanged.

When queueing a set element add or removal operation to the transaction
log, check if the previous operation already asks for a the identical
operation on the same set.
If so, store the element reference in the preceding operation.
This significantlty reduces memory consumption when many set add/delete
operations appear in a single transaction.
Example: 10k elements require 937kb of memory (10k allocations from
kmalloc-96 slab).
Assuming we can compact 4 elements in the same set, 468 kbytes
are needed (64 bytes for base struct, nft_trans_elemn, 32 bytes
for nft_trans_one_elem structure, so 2500 allocations from kmalloc-192
slab).
For large batch updates we can compact up to 62 elements
into one single nft_trans_elem structure (~65% mem reduction):
(64 bytes for base struct, nft_trans_elem, 32 byte for nft_trans_one_elem
struct).
We can halve size of nft_trans_one_elem struct by moving
timeout/expire/update_flags into a dynamically allocated structure,
this allows to store 124 elements in a 2k slab nft_trans_elem struct.
This is done in a followup patch.

nftables audit log format emits the number of added/deleted rules, sets,
set elements and so on, to userspace:
table=t1 family=2 entries=4 op=nft_register_set
~~~~~~~~~
At this time, the 'entries' key is the number of transactions that will
be applied.
The upcoming set element compression will coalesce subsequent
adds/deletes to the same set requests in the same transaction
request to conseve memory.
Without this patch, we'd under-report the number of altered elements.
Increment the audit counter by the number of elements to keep the reported
entries value the same.
Without this, nft_audit.sh selftest fails because the recorded
(expected) entries key is smaller than the expected one.

Add helpers to release the individual elements contained in the
trans_elem container structure.
No functional change intended.
Followup patch will add 'nelems' member and will turn 'priv' into
a flexible array.
These helpers can then loop over all elements.
Care needs to be taken to handle a mix of new elements and existing
elements that are being updated (e.g. timeout refresh).
Before this patch, NEWSETELEM transaction with update is released
early so nft_trans_set_elem_destroy() won't get called, so we need
to skip elements marked as update.

It is always the case where the contents of mod is safe to pass as the
format argument. That is, in my understanding, it never contains any
format escape sequences.
But, it seems better to be safe than sorry. And, as a bonus, compiler
output becomes less verbose by addressing this issue as suggested by
clang-18.
Compile tested only.

So far the mux changes it state immediately, even when not in use. Allow
overriding this behaviour by specifying an optional idle-state. This
state is used whenever the mux is powered down, only switching to the
selected state on power up. If unspecified it defaults to as-is,
maintaining the previous behaviour.

bonding: fix ns targets not work on hardware NIC
The first patch fixed ns targets not work on hardware NIC when bonding
set arp_validate.
The second patch add a related selftest for bonding.
v4: Thanks Nikolay for the comments:
use bond_slave_ns_maddrs_{add/del} with clear name
fix comments typos
remove _slave_set_ns_maddrs underscore directly
update bond_option_arp_validate_set() change logic
v3: use ndisc_mc_map to convert the mcast mac address (Jay Vosburgh)
v2: only add/del mcast group on backup slaves when arp_validate is set (Jay Vosburgh)
arp_validate doesn't support 3ad, tlb, alb. So let's only do it on ab mode.

Commit 4598380f9c54 ("bonding: fix ns validation on backup slaves")
tried to resolve the issue where backup slaves couldn't be brought up when
receiving IPv6 Neighbor Solicitation (NS) messages. However, this fix only
worked for drivers that receive all multicast messages, such as the veth
interface.
For standard drivers, the NS multicast message is silently dropped because
the slave device is not a member of the NS target multicast group.
To address this, we need to make the slave device join the NS target
multicast group, ensuring it can receive these IPv6 NS messages to validate
the slave’s status properly.
There are three policies before joining the multicast group:
1. All settings must be under active-backup mode (alb and tlb do not support
arp_validate), with backup slaves and slaves supporting multicast.
2. We can add or remove multicast groups when arp_validate changes.
3. Other operations, such as enslaving, releasing, or setting NS targets,
need to be guarded by arp_validate.

DIP algorithm requires a one-to-one mapping between dgid and dip_idx.
Currently a queue 'spare_idx' is used to store QPN of QPs that use
DIP algorithm. For a new dgid, use a QPN from spare_idx as dip_idx.
This method lacks a mechanism for deduplicating QPN, which may result
in different dgids sharing the same dip_idx and break the one-to-one
mapping requirement.
This patch replaces spare_idx with xarray and introduces a refcnt of
a dip_idx to indicate the number of QPs that using this dip_idx.
The state machine for dip_idx management is implemented as:
* The entry at an index in xarray is empty -- This indicates that the
corresponding dip_idx hasn't been created.
* The entry at an index in xarray is not empty but with 0 refcnt --
This indicates that the corresponding dip_idx has been created but
not used as dip_idx yet.
* The entry at an index in xarray is not empty and with non-0 refcnt --
This indicates that the corresponding dip_idx is being used by refcnt
number of DIP QPs.

If CONFIG_DMA_GLOBAL_POOL=y, the reserved_mem structure passed to
rmem_dma_setup() is saved for later use, by saving the passed pointer.
However, when dma_init_reserved_memory() is called later, the pointer
has become stale, causing a crash.
E.g. in the RZ/Five case, the referenced memory now contains the
reserved_mem structure for the "mmode_resv0@30000" node (with base
0x30000 and size 0x10000), instead of the correct "pma_resv0@58000000"
node (with base 0x58000000 and size 0x8000000).
Fix this by saving the needed reserved_mem structure's contents instead.

Previously any PMU overflow interrupt that fired while a VCPU was
loaded was recorded as a guest event whether it truly was or not. This
resulted in nonsense perf recordings that did not honor
perf_event_attr.exclude_guest and recorded guest IPs where it should
have recorded host IPs.
Rework the sampling logic to only record guest samples for events with
exclude_guest = 0. This way any host-only events with exclude_guest
set will never see unexpected guest samples. The behaviour of events
with exclude_guest = 0 is unchanged.
Note that events configured to sample both host and guest may still
misattribute a PMI that arrived in the host as a guest event depending
on KVM arch and vendor behavior.
