We recently added some validation that we don't try to
connect to an AP that is currently in a channel switch
process, since that might want the channel to be quiet
or we might not be able to connect in time to hear the
switching in a beacon. This was in commit c09c4f3199
("wifi: mac80211: don't connect to an AP while it's in
a CSA process").
However, we promptly got a report that this caused new
connection failures, and it turns out that the AP that
we now cannot connect to is permanently advertising an
extended channel switch announcement, even with quiet.
The AP in question was an Asus RT-AC53, with firmware
3.0.0.4.380_10760-g21a5898.
As a first step, attempt to detect that we're dealing
with such a situation, so mac80211 can use this later.

Sometimes there may be reasons for which a BSS that's
actually found in scan cannot be used to connect to,
for example a nonprimary link of an NSTR mobile AP MLD
cannot be used for normal direct connections to it.
Not indicating these to userspace as we do now of course
avoids being able to connect to them, but it's better if
they're shown to userspace and it can make an appropriate
decision, without e.g. doing an additional ML probe.
Thus add an indication of what a BSS can be used for,
currently "normal" and "MLD link", including a reason
bitmap for it being not usable.
The latter can be extended later for certain BSSes if there
are other reasons they cannot be used.

The removed code ran for any BSS that was not included in the MBSSID
element in order to update it. However, instead of using the correct
inheritance rules, it would simply copy the elements from the
transmitting AP. The result is that we would report incorrect elements
in this case.
After some discussions, it seems that there are likely not even APs
actually using this feature. Either way, removing the code decreases
complexity and makes the cfg80211 behaviour more correct.

The cfg80211_gen_new_ie function merges the IEs using inheritance rules.
Rewrite this function to fix issues around inheritance rules. In
particular, vendor elements do not require any special handling, as they
are either all inherited or overridden by the subprofile.
Also, add fragmentation handling as this may be needed in some cases.
This also changes the function to not require making a copy. The new
version could be optimized a bit by explicitly tracking which IEs have
been handled already rather than looking that up again every time.
Note that a small behavioural change is the removal of the SSID special
handling. This should be fine for the MBSSID element, as the SSID must
be included in the subelement.

The check that beacon primary channel is in the range of 80 MHz
(abs < 80) is invalid for 320 MHz since duplicate beacon transmit
means that the AP transmits it on all the 20 MHz sub-channels:
9.4.2.249 HE Operation element - ... AP transmits Beacon frames in
non-HT duplicate PPDU with a TXVECTOR parameter CH_BANDWIDTH value
that is up to the BSS bandwidth.
So in case of 320 MHz the DUP beacon can be in upper 160 for primary
channel in the lower 160 giving possibly an absolute range of over
80 MHz.
Also this check is redundant alltogether, if AP has a wrong primary
channel in the beacon it's a faulty AP, and we would fail in next
steps to connect.
While at it, fix the frequency comparison to no longer compare
between KHz and MHz, which was introduced by commit 7f599aeccb

Currently in case DUP bit is not set we don't return the primary
channel for 6 GHz Band, but the spec says that the DUP bit has
no effect on this field:
9.4.2.249 HE Operation element:
The Duplicate Beacon subfield is set to 1 if the AP transmits
Beacon frames in non-HT duplicate PPDU with a TXVECTOR parameter
CH_BANDWIDTH value that is up to the BSS bandwidth and is set to
0 otherwise.
So remove the condition for returning primary channel based on DUP.
Since the caller code already marks the signal as invalid in case
the indicated frequency is not the tuned frequency, there's no need
to additionally handle this case here since that's already true for
duplicated beacons on the non-primary channel(s).

There's no need to open-code container_of() when we have
bss_from_pub(). Use it.

If the "channel->freq_offset" comparison is omitted in cmp_bss(),
BSS with different kHz units cannot be distinguished in the S1G Band.
So "freq_offset" should also be included in the comparison.

In S1G beacon frames there shouldn't be multi-BSSID elements
since that's not supported, remove that to avoid a potential
integer underflow and/or misparsing the frames due to the
different length of the fixed part of the frame.
While at it, initialize non_tx_data so we don't send garbage
values to the user (even if it doesn't seem to matter now.)

For vendor elements, the code here assumes that 5 octets
are present without checking. Since the element itself is
already checked to fit, we only need to check the length.

Second set of patches for v6.2. Only driver patches this time, nothing
really special. Unused platform data support was removed from wl1251
and rtw89 got WoWLAN support.
Major changes:
ath11k
* support configuring channel dwell time during scan
rtw89
* new dynamic header firmware format support
* Wake-over-WLAN support
rtl8xxxu
* enable IEEE80211_HW_SUPPORT_FAST_XMIT

When built with Control Flow Integrity, function prototypes between
caller and function declaration must match. These mismatches are visible
at compile time with the new -Wcast-function-type-strict in Clang[1].
Fix a total of 73 warnings like these:
drivers/net/wireless/intersil/orinoco/wext.c:1379:27: warning: cast from 'int (*)(struct net_device *, struct iw_request_info *, struct iw_param *, char *)' to 'iw_handler' (aka 'int (*)(struct net_device *, struct iw_request_info *, union iwreq_data *, char *)') converts to incompatible function type [-Wcast-function-type-strict]

IW_HANDLER(SIOCGIWRETRY, cfg80211_wext_giwretry),
^~~~~~~~~~~~~~~~~~~~~~
The cfg80211 Wireless Extension handler callbacks (iw_handler) use a
union for the data argument. Actually use the union and perform explicit
member selection in the function body instead of having a function
prototype mismatch. There are no resulting binary differences
before/after changes.
These changes were made partly manually and partly with the help of
Coccinelle.
