The minimum header length calculation (equivalent to the start
of the elements) for the S1G long beacon erroneously required
only up to the start of u.s1g_beacon rather than the start of
u.s1g_beacon.variable. Fix that, and also shuffle the branches
around a bit to not assign useless values that are overwritten
later.

Individual MLO links connection status is not copied to
EVENT_CONNECT_RESULT data while processing the connect response
information in cfg80211_connect_done(). Due to this failed links
are wrongly indicated with success status in EVENT_CONNECT_RESULT.
To fix this, copy the individual MLO links status to the
EVENT_CONNECT_RESULT data.

The prerequisite for MLO support in cfg80211/mac80211 is that all the links
participating in MLO must be from the same wiphy/ieee80211_hw. To meet this
expectation, some drivers may need to group multiple discrete hardware each
acting as a link in MLO under single wiphy.
With this change, supported frequencies and interface combinations of each
individual radio are reported to user space. This allows user space to figure
out the limitations of what combination of channels can be used concurrently.
Even for non-MLO devices, this improves support for devices capable of
running on multiple channels at the same time.

When a key is requested by userspace, there's really no need
to include the key data, the sequence counter is really what
userspace needs in this case. The fact that it's included is
just a historic quirk.
Remove the key data.

If a user uses iw to connect to a network and we don't have any
information about the existing networks, cfg80211 will trigger a scan
internally even if the user didn't ask for a scan. This scan is
implemented by cfg80211_conn_scan(). This function called rdev_scan()
directly without honoring the WIPHY_FLAG_SPLIT_SCAN_6GHZ flag.
Use cfg80211_scan instead, this will split the scan if the low level
driver asked to.

On 6 GHz (and also 5 GHz to some degree), only a specific set of center
frequencies should be used depending on the channel bandwidth. Verify
this is the case on 6 GHz. For 5 GHz, we are more accepting as there are
APs that got it wrong historically.

Add a regulatory flag to allow VLP AP operation even on
channels otherwise marked NO_IR, which may be possible
in some regulatory domains/countries.
Note that this requires checking also when the beacon is
changed, since that may change the regulatory power type.

To later introduce an override for VLP APs being allowed despite
NO-IR flags, which is somewhat similar in construction to being
allowed to monitor on disabled channels, refactor the code that
checks channel flags to have not a 'monitor' argument but a set
of 'permitting' flags that permit the operation without checking
for 'prohibited' flags.

Jiazi Li reported that they occasionally see hash table duplicates
as evidenced by the WARN_ON() in rb_insert_bss() in this code. It
isn't clear how that happens, nor have I been able to reproduce it,
but if it does happen, the kernel crashes later, when it tries to
unhash the entry that's now not hashed.
Try to make this situation more survivable by removing the BSS from
the list(s) as well, that way it's fully leaked here (as had been
the intent in the hash insert error path), and no longer reachable
through the list(s) so it shouldn't be unhashed again later.

In nl80211, we always set the ssids of a scan request to
NULL when n_ssids==0 (passive scan). Drivers have relied
on this behaviour in the past, so we fixed it in 6 GHz
scan requests as well, and added a warning so we'd have
assurance the API would always be called that way.
syzbot found that wext doesn't ensure that, so we reach
the check and trigger the warning. Fix the wext code to
set the ssids pointer to NULL when there are none.

There's no need to allocate a tiny struct and then
an array again, just allocate the two together and
use __counted_by(). Also unify the freeing.

Just like it's not currently possible to start radar
detection while already operating, it shouldn't be
possible to start operating while radar detection is
running. Fix that.
Also, improve the check whether operating (carrier
might not be up if e.g. attempting to join IBSS).

add an event when the worker starts, before acquiring the

20/40/... MHz channel width progression, and switching around

The 6 GHz scan request struct allocated by cfg80211_scan_6ghz() is
meant to be formed this way:
[base struct][channels][ssids][6ghz_params]
It is allocated with [channels] as the maximum number of channels
supported by the driver in the 6 GHz band, since allocation is
before knowing how many there will be.
However, the inner pointers are set incorrectly: initially, the
6 GHz scan parameters pointer is set:
[base struct][channels]
^ scan_6ghz_params
and later the SSID pointer is set to the end of the actually
_used_ channels.
[base struct][channels]
^ ssids
If many APs were to be discovered, and many channels used, and
there were many SSIDs, then the SSIDs could overlap the 6 GHz
parameters.
Additionally, the request->ssids for most of the function points
to the original request still (given the struct copy) but is used
normally, which is confusing.
Clear this up, by actually using the allocated space for 6 GHz
parameters _after_ the SSIDs, and set up the SSIDs initially so
they are used more clearly. Just like in nl80211.c, set them
only if there actually are SSIDs though.
Finally, also copy the elements (ie/ie_len) so they're part of
the same request, not pointing to the old request.

The commit 9bb7e0f24e7e ("cfg80211: add peer measurement with FTM
initiator API") defines four attributes NL80211_PMSR_FTM_REQ_ATTR_
{NUM_BURSTS_EXP}/{BURST_PERIOD}/{BURST_DURATION}/{FTMS_PER_BURST} in
following ways.
static const struct nla_policy
nl80211_pmsr_ftm_req_attr_policy[NL80211_PMSR_FTM_REQ_ATTR_MAX + 1] = {
...
[NL80211_PMSR_FTM_REQ_ATTR_NUM_BURSTS_EXP] =
NLA_POLICY_MAX(NLA_U8, 15),
[NL80211_PMSR_FTM_REQ_ATTR_BURST_PERIOD] = { .type = NLA_U16 },
[NL80211_PMSR_FTM_REQ_ATTR_BURST_DURATION] =
NLA_POLICY_MAX(NLA_U8, 15),
[NL80211_PMSR_FTM_REQ_ATTR_FTMS_PER_BURST] =
NLA_POLICY_MAX(NLA_U8, 31),
...
};
That is, those attributes are expected to be NLA_U8 and NLA_U16 types.
However, the consumers of these attributes in `pmsr_parse_ftm` blindly
all use `nla_get_u32`, which is incorrect and causes functionality issues
on little-endian platforms. Hence, fix them with the correct `nla_get_u8`
and `nla_get_u16` functions.

This happens because STA has time to disconnect and reconnect before

this situation, ath10k_sta_state() can be in the middle of resetting
arsta data when the work queue get chance to be scheduled and ends up
accessing it. Locking wiphy prevents that.

With the rework of how the __string() handles dynamic strings where it
saves off the source string in field in the helper structure[1], the
assignment of that value to the trace event field is stored in the helper
value and does not need to be passed in again.
This means that with:
__string(field, mystring)
Which use to be assigned with __assign_str(field, mystring), no longer
needs the second parameter and it is unused. With this, __assign_str()
will now only get a single parameter.
There's over 700 users of __assign_str() and because coccinelle does not
handle the TRACE_EVENT() macro I ended up using the following sed script:
git grep -l __assign_str | while read a ; do
sed -e 's/\(__assign_str([^,]*[^ ,]\) *,[^;]*/\1)/' $a > /tmp/test-file;
mv /tmp/test-file $a;
done
I then searched for __assign_str() that did not end with ';' as those
were multi line assignments that the sed script above would fail to catch.
Note, the same updates will need to be done for:
__assign_str_len()
__assign_rel_str()
__assign_rel_str_len()
I tested this with both an allmodconfig and an allyesconfig (build only for both).

Pull Kbuild updates from Masahiro Yamada:
- Avoid 'constexpr', which is a keyword in C23
- Allow 'dtbs_check' and 'dt_compatible_check' run independently of
'dt_binding_check'
- Fix weak references to avoid GOT entries in position-independent code
generation
- Convert the last use of 'optional' property in arch/sh/Kconfig
- Remove support for the 'optional' property in Kconfig
- Remove support for Clang's ThinLTO caching, which does not work with
the .incbin directive

Kbuild conventionally uses $(obj)/ for generated files, and $(src)/ for
checked-in source files. It is merely a convention without any functional
difference. In fact, $(obj) and $(src) are exactly the same, as defined
in scripts/Makefile.build:
src := $(obj)
When the kernel is built in a separate output directory, $(src) does
not accurately reflect the source directory location. While Kbuild
resolves this discrepancy by specifying VPATH=$(srctree) to search for
source files, it does not cover all cases. For example, when adding a
header search path for local headers, -I$(srctree)/$(src) is typically
passed to the compiler.
This introduces inconsistency between upstream and downstream Makefiles
because $(src) is used instead of $(srctree)/$(src) for the latter.
To address this inconsistency, this commit changes the semantics of
$(src) so that it always points to the directory in the source tree.
Going forward, the variables used in Makefiles will have the following
meanings:
$(obj) - directory in the object tree
$(src) - directory in the source tree (changed by this commit)
$(objtree) - the top of the kernel object tree
$(srctree) - the top of the kernel source tree
Consequently, $(srctree)/$(src) in upstream Makefiles need to be replaced
with $(src).

Before request->channels[] can be used, request->n_channels must be set.
Additionally, address calculations for memory after the "channels" array
need to be calculated from the allocation base ("request") rather than
via the first "out of bounds" index of "channels", otherwise run-time
bounds checking will throw a warning.

git://git.kernel.org/pub/scm/linux/kernel/git/wireless/wireless-next
Kalle Valo says:
====================
wireless-next patches for v6.10
The first "new features" pull request for v6.10 with changes both in
stack and in drivers. The big thing in this pull request is that
wireless subsystem is now almost free of sparse warnings. There's only
one warning left in ath11k which was introduced in v6.9-rc1 and will
be fixed via the wireless tree.
Realtek drivers continue to improve, now we have support for RTL8922AE
and RTL8723CS devices. ath11k also has long waited support for P2P.
This time we have a small conflict in iwlwifi, Stephen has an example
merge resolution which should help with fixing the conflict:
https://lore.kernel.org/all/20240326100945.765b8caf@canb.auug.org.au/
Major changes:
rtw89
* RTL8922AE Wi-Fi 7 PCI device support
rtw88
* RTL8723CS SDIO device support
iwlwifi
* don't support puncturing in 5 GHz
* support monitor mode on passive channels
* BZ-W device support
* P2P with HE/EHT support
ath11k
* P2P support for QCA6390, WCN6855 and QCA2066

If a non-TX BSS is included in a per-STA profile, then we cannot set
transmitted_bss for it. Even worse, if we do things properly we should
be configuring both bssid_index and max_bssid_indicator correctly. We do
not actually have both pieces of information (and, some APs currently
do not include either).
So, ignore any per-STA profile where the RNR says that the BSS is not
transmitted. Also fix transmitted_bss to never be set for per-STA
profiles.
This fixes issues where mac80211 was setting the reference BSSID to an
incorrect value.
