We sometimes need to check if a link is active, and this
is complicated by the fact that active_links has no bits
set when the vif isn't (acting as) an MLD. Add a small
new helper ieee80211_vif_link_active() to make that a bit
easier, and use it in a few places.

The CQM handling did not consider the MLO case and thus notified
a not-existing link with the CQM change. To fix this, propagate
the CQM notification to all the active links (handling both the
non-MLO and MLO cases).
TODO: this currently propagates the same configuration to all
links regardless of the band. This might not be the correct
approach as different links might need to be configured with
different values.

In the association request, we make some parameters depend on the
AP's HT/VHT information. This was broken by my code because it no
longer filled that information, making it all zero.
For HT that meant we wouldn't reduce our capabilities to 20 MHz if
needed, and for VHT we lost beamforming capabilities.
Fix this. It seems like it may even have been broken for all but
the assoc link before.

When a link doesn't have VHT capability, before the rework
we'd have set IEEE80211_CONN_DISABLE_VHT, but now with the
linear progression of 'mode', we no longer have that. Add
an explicit check for VHT being supported, so we don't add
a zeroed VHT capabilities element where it shouldn't be.

Currently whenever link AP is started, netif_carrier_up() function is
called and whenever it is brought down, netif_carrier_down() function is
called. However, with MLO, all the links of the same MLD would use the
same netdev. Hence there is no need to indicate for each link up/down.
Also, calling it down when only one of the links went down is not
desirable.
Add changes to call the netif_carrier_up() function only when first link
is brought up. Similarly, add changes to call the netif_carrier_down()
function only when last link is brought down.
In order to check the number of beaconing links in the given interface,

We're currently tracking rx_nss for each station, and that
is meant to be initialized to the capability NSS and later
reduced by the operating mode notification NSS.
However, we're mixing up capabilities and operating mode
NSS in the same variable. This forces us to recalculate
the NSS capability on operating mode notification RX,
which is a bit strange; due to the previous fix I had to
never keep rx_nss as zero, it also means that the capa is
never taken into account properly.
Fix all this by storing the capability value, that can be
recalculated unconditionally whenever needed, and storing
the operating mode notification NSS separately, taking it
into account when assigning the final rx_nss value.

There's a somewhat common pattern of using FIELD_PREP()
even for single bits, e.g.
cmd->info1 |= FIELD_PREP(HTT_SRNG_SETUP_CMD_INFO1_RING_FLAGS_MSI_SWAP,
!!(params.flags & HAL_SRNG_FLAGS_MSI_SWAP));
which might as well be written as
if (params.flags & HAL_SRNG_FLAGS_MSI_SWAP)
cmd->info1 |= HTT_SRNG_SETUP_CMD_INFO1_RING_FLAGS_MSI_SWAP;
(since info1 is fully initialized to start with), but in
a long chain of FIELD_PREP() this really seems fine.
However, it triggers a sparse warning, in the check in
the macro for whether a constant value fits into the mask,
as this contains a "& (_val)". In this case, this really
is always intentional, so just suppress the warning by
adding "0+" to the expression, indicating explicitly that
this is correct.

Fix boot crash on Raspberry Pi by moving the update to `event->datalen`
before data is copied into flexible-array member `data` via `memcpy()`.
Flexible-array member `data` was annotated with `__counted_by(datalen)`
in commit 62d19b358088 ("wifi: brcmfmac: fweh: Add __counted_by for
struct brcmf_fweh_queue_item and use struct_size()"). The intention of
this is to gain visibility into the size of `data` at run-time through
its _counter_ (in this case `datalen`), and with this have its accesses
bounds-checked at run-time via CONFIG_FORTIFY_SOURCE and
CONFIG_UBSAN_BOUNDS.
To effectively accomplish the above, we shall update the counter
(`datalen`), before the first access to the flexible array (`data`),
which was also done in the mentioned commit.
However, commit edec42821911 ("wifi: brcmfmac: allow per-vendor event
handling") inadvertently caused a buffer overflow, detected by
FORTIFY_SOURCE. It moved the `event->datalen = datalen;` update to after
the first `data` access, at which point `event->datalen` was not yet
updated from zero (after calling `kzalloc()`), leading to the overflow
issue.
This fix repositions the `event->datalen = datalen;` update before
accessing `data`, restoring the intended buffer overflow protection. :)

Through the routine bond_mii_monitor(), bonding driver inspects and commits
the slave state changes. During the times when slave state change and
failure in aqcuiring rtnl lock happen at the same time, the routine
bond_mii_monitor() reschedules itself to come around after 1 msec to commit
the new state.
During this, it executes the routine bond_miimon_inspect() to re-inspect
the state chane and prints the corresponding slave state on to the console.
Hence we do see a message at every 1 msec till the rtnl lock is acquired
and state chage is committed.
This patch doesn't change how bond functions. It only simply limits this

Florian Westphal says:
====================
netfilter updates for net-next
1. Prefer KMEM_CACHE() macro to create kmem caches, from Kunwu Chan.
Patches 2 and 3 consolidate nf_log NULL checks and introduces
extra boundary checks on family and type to make it clear that no out
of bounds access will happen. No in-tree user currently passes such
values, but thats not clear from looking at the function.
From Pablo Neira Ayuso.
Patch 4, also from Pablo, gets rid of unneeded conditional in
nft_osf init function.
Patch 5, from myself, fixes erroneous Kconfig dependencies that
came in an earlier net-next pull request. This should get rid
of the xtables related build failure reports.
Patches 6 to 10 are an update to nftables' concatenated-ranges
set type to speed up element insertions. This series also
compacts a few data structures and cleans up a few oddities such
as reliance on ZERO_SIZE_PTR when asking to allocate a set with
no elements. From myself.
Patches 11 moves the nf_reinject function from the netfilter core
(vmlinux) into the nfnetlink_queue backend, the only location where
this is called from. Also from myself.
Patch 12, from Kees Cook, switches xtables' compat layer to use
unsafe_memcpy because xt_entry_target cannot easily get converted
to a real flexible array (its UAPI and used inside other structs).

With commit 34d21de99cea9 ("net: Move {l,t,d}stats allocation to core and
convert veth & vrf"), stats allocation could be done on net core
instead of this driver.
With this new approach, the driver doesn't have to bother with error
handling (allocation failure checking, making sure free happens in the
right spot, etc). This is core responsibility now.
Remove the allocation in the ipv6/sit driver and leverage the network
core allocation.

wireless-next patches for v6.9
The third "new features" pull request for v6.9. This is a quick
followup to send commit 04edb5dc68f4 ("wifi: ath12k: Fix uninitialized
use of ret in ath12k_mac_allocate()") to fix the ath12k clang warning
introduced in the previous pull request.
We also have support for QCA2066 in ath11k, several new features in
ath12k and few other changes in drivers. In stack it's mostly cleanup
and refactoring.
Major changes:
ath12k

Pull tracing fix from Steven Rostedt:
- While working on the ring buffer I noticed that the counter used for
knowing where the end of the data is on a sub-buffer was not a full
"int" but just 20 bits. It was masked out to 0xfffff.
With the new code that allows the user to change the size of the
sub-buffer, it is theoretically possible to ask for a size bigger
than 2^20. If that happens, unexpected results may occur as there's
no code checking if the counter overflowed the 20 bits of the write
mask. There are other checks to make sure events fit in the
sub-buffer, but if the sub-buffer itself is too big, that is not
checked.
Add a check in the resize of the sub-buffer to make sure that it
never goes beyond the size of the counter that holds how much data is
on it.

====================
bnxt_en: Ntuple filter improvements
The current Ntuple filter implementation has a limitation on 5750X (P5)
and newer chips. The destination ring of the ntuple filter must be
a valid ring in the RSS indirection table. Ntuple filters may not work
if the RSS indirection table is modified by the user to only contain a
subset of the rings. If an ntuple filter is set to a ring destination
that is not in the RSS indirection table, the packet matching that
filter will be placed in a random ring instead of the specified
destination ring.
This series of patches will fix the problem by using a separate VNIC
for ntuple filters. The default VNIC will be dedicated for RSS and
so the indirection table can be setup in any way and will not affect
ntuple filters using the separate VNIC.
Quite a bit of refactoring is needed to do the the VNIC and RSS
context accounting in the first few patches. This is technically a
bug fix, but I think the changes are too big for -net.

The newly created vnic (BNXT_VNIC_NTUPLE) is ready to be used to create
ntuple filters when supported by firmware. All RX rings can be used
regardless of the RSS indirection setting on the default VNIC.

Allocate and setup the additional VNIC for ntuple filters if this
new method is supported by the firmware. Even though this VNIC is
only used for ntuple filters with direct ring destinations, we still
setup the RSS hash to be identical to the default VNIC so that each
RX packet will have the correct hash in the RX completion. This
VNIC is always at VNIC index BNXT_VNIC_NTUPLE.

On newer chips that support the ring table index method for
ntuple filters, the current scheme of using the same VNIC for
both RSS and ntuple filters will not work in all cases. An
ntuple filter can only be directed to a destination ring if
that destination ring is also in the RSS indirection table.
To support ntuple filters with any arbitratry RSS indirection
table that may only include a subset of the rings, we need to
use a separate VNIC for ntuple filters.
This patch provisions the additional VNIC. The next patch will
allocate additional VNIC from firmware and set it up.

bnxt_check_rings() is called to check if we have enough resource
assets to satisfy the new number of ethtool channels. If the asset
test fails, the ethtool operation will fail gracefully. Otherwise
we will proceed and commit to use the new number of channels. If it
fails to allocate any resources, the chip will fail to come up.
For completeness, check all possible resources before committing to
the new settings. Add the missing ring group and RSS context asset
tests in bnxt_check_rings().

Add RSS context fields to struct bnxt_hw_rings and struct bnxt_hw_resc.
With these, we can now specific the exact number of RSS contexts to
reserve and store the reserved value. The original code relies on
other resources to infer the number of RSS contexts to reserve and the
reserved value is not stored. This improved infrastructure will make
the RSS context accounting more complete and is needed by later
patches.

The current code assumes that every RX ring group and every TX ring
requires a completion ring on P5_PLUS chips. Now that we have the
bnxt_hw_rings structure, add the cp_p5 field so that it can
be explicitly specified. This makes the logic more clear.

The current functions to reserve hardware rings pass in 6 different ring
or resource types as parameters. Add a structure bnxt_hw_rings to
consolidate all these parameters and pass the structure pointer instead
to these functions. Add 2 related helper functions also. This makes
the code cleaner and makes it easier to add new resources to be
reserved.
