9e23063a79 wifi: mac80211: make monitor link info check more specific
Verify that only one of the permitted change flags is set when changing
the link of a monitor interface. Before the WARN_ON_ONCE would accept
anything if mu_mimo_owner was set.

Also, split out the mu_mimo_owner flag and enable it for all interface
types. The option is set during association when VHT is available and it
is not expected that any configuration of the MU groups is done without
it being set.

a5aa46f1ac wifi: mac80211: track MU-MIMO configuration on disabled interfaces
For monitoring, userspace will try to configure the VIF sdata, while the
driver may see the monitor_sdata that is created when only monitor
interfaces are up. This causes the odd situation that it may not be
possible to store the MU-MIMO configuration on monitor_sdata.

Fix this by storing that information on the VIF sdata and updating the
monitor_sdata when available and the interface is up. Also, adjust the
code that adds monitor_sdata so that it will configure MU-MIMO based on
the newly added interface or one of the existing ones.

This should give a mostly consistent behaviour when configuring MU-MIMO
on sniffer interfaces. Should the user configure MU-MIMO on multiple
sniffer interfaces, then mac80211 will simply select one of the
configurations. This behaviour should be good enough and avoids breaking
user expectations in the common scenarios.

a1dc648aa7 wifi: mac80211: remove chanctx to link back-references
Each link can currently use a chanctx and have another one
reserved, and both of these are also tracked backwards in
the assigned_links and reserved_links lists. If we consider
that there aren't *that* many links, this duplicate book-
keeping isn't necessary.
(I think it used to be necessary before the wiphy locking
changes, when chanctx_mtx existed, because we couldn't do
any interface iterations while holding only chanctx_mtx.)

Additionally, for NAN, we're going to want to track which
chanctxs are in use by the (group of) NAN interfaces. For
those, links don't really make sense as such, so chanctxs
need to be assigned to a different data structure.

Thus, as a first step, remove those back-lists of users
(right now only links) of each channel context. This is a
very basic conversion, ieee80211_vif_use_reserved_switch()
should made to iterate smarter.

29cc798e70 wifi: mac80211: make link iteration safe for 'break'
The current link iteration macros for_each_sdata_link() and
for_each_sdata_link_rcu() are various nested for loops, but
because they iterate all sdata instances and then all links
inside, using 'break' inside the iteration doesn't actually
break out of the whole iteration.

Make it work by tracking whether or not the inner iteration
(over links) actually completed, if it broke out then given
list_for_each_entry() it still iterates all sdata instances
but won't go into them.

a9da90e618 wifi: mac80211: reject address change while connecting
While connecting, the MAC address can already no longer be
changed. The change is already rejected if netif_carrier_ok(),
but of course that's not true yet while connecting. Check for
auth_data or assoc_data, so the MAC address cannot be changed.

Also more comprehensively check that there are no stations on
the interface being changed - if any peer station is added it
will know about our address already, so we cannot change it.

mac80211 already reports some basic information in the radiotap header

should be pulled from the skb. Update the code to fill in the VHT fields
to only do so when requested by the driver or if the information has not

a392cde88d wifi: cfg80211/mac80211: validate radio frequency range for monitor mode
In multi-radio devices, it is possible to have an MLD AP and a monitor
interface active at the same time. In such cases, monitor mode may not
be able to specify a fixed channel and could end up capturing frames
from all radios, including those outside the intended frequency bands.

This patch adds frequency validation for monitor mode. Received frames
are now only processed if their frequency fall within the allowed ranges
of the radios specified by the interface's radio_mask.

This prevents monitor mode from capturing frames outside the supported radio.

In ieee80211_rx_handle_packet(), if the caller does not provide pubsta
information, an attempt is made to find the station using the address 2

information such as link_valid and link_id is also unavailable. Now if such

in the status field which is not correct.

Hence, to fix this issue, if link_valid is not set and the station is an
ML station, make an attempt to find a link station entry using the source
address. If a valid link station is found, derive the link ID and proceed
with packet processing. Otherwise, drop the packet as per the existing
flow.

872e397d62 wifi: mac80211: Remove redundant rcu_read_lock/unlock() in spin_lock
Since commit a8bb74acd8 ("rcu: Consolidate RCU-sched update-side function definitions")
there is no difference between rcu_read_lock(), rcu_read_lock_bh() and
rcu_read_lock_sched() in terms of RCU read section and the relevant grace
period. That means that spin_lock(), which implies rcu_read_lock_sched(),
also implies rcu_read_lock().

There is no need no explicitly start a RCU read section if one has already
been started implicitly by spin_lock().

Simplify the code and remove the inner rcu_read_lock() invocation.

906a5a8c71 wifi: mac80211: add tx_handlers_drop statistics to ethtool
Currently tx_handlers_drop statistics are handled only for slow TX
path and only at radio level. This also requires
CONFIG_MAC80211_DEBUG_COUNTERS to be enabled to account the dropped
packets. There is no way to check these stats for fast TX,
at interface level and monitor without enabling the debug configuration.

Hence, add a new counter at the sdata level to track packets dropped
with reason as TX_DROP during transmission for fast path, slow path
and other tx management packets. Expose this via ethtool statistics,
to improve visibility into transmission failures at interface level
and aid debugging and performance monitoring.

Place the counter in ethtool with other available tx_* stats for
better readability and accurate tracking.

eebccbfea4 wifi: mac80211: fix reporting of all valid links in sta_set_sinfo()
Currently, sta_set_sinfo() fails to populate link-level station info
when sinfo->valid_links is initially 0 and sta->sta.valid_links has
bits set for links other than link 0. This typically occurs when
association happens on a non-zero link or link 0 deleted dynamically.
In such cases, the for_each_valid_link(sinfo, link_id) loop only
executes for link 0 and terminates early, since sinfo->valid_links
remains 0. As a result, only MLD-level information is reported to
userspace.

Hence to fix, initialize sinfo->valid_links with sta->sta.valid_links
before entering the loop to ensure loop executes for each valid link.
During iteration, mask out invalid links from sinfo->valid_links if
any of sta->link[link_id], sdata->link[link_id], or sinfo->links[link_id]
are not present, to report only valid link information.

e53f8b12a2 wifi: mac80211: Fix 6 GHz Band capabilities element advertisement in lower bands
Currently, when adding the 6 GHz Band Capabilities element, the channel
list of the wiphy is checked to determine if 6 GHz is supported for a given
virtual interface. However, in a multi-radio wiphy (e.g., one that has
both lower bands and 6 GHz combined), the wiphy advertises support for
all bands. As a result, the 6 GHz Band Capabilities element is incorrectly
included in mesh beacon and station's association request frames of
interfaces operating in lower bands, without verifying whether the
interface is actually operating in a 6 GHz channel.

Fix this by verifying if the interface operates on 6 GHz channel
before adding the element. Note that this check cannot be placed
directly in ieee80211_put_he_6ghz_cap() as the same function is used to
add probe request elements while initiating scan in which case the
interface may not be operating in any band's channel.

36b75dcb1e wifi: mac80211: consider links for validating SCAN_FLAG_AP in scan request during MLO
Commit 78a7a126dc ("wifi: mac80211: validate SCAN_FLAG_AP in scan request
during MLO") introduced a check that rejects scan requests if any link is
already beaconing. This works fine when all links share the same radio, but
breaks down in multi-radio setups.

Consider a scenario where a 2.4 GHz link is beaconing and a scan is
requested on a 5 GHz link, each backed by a different physical radio. The
current logic still blocks the scan, even though it should be allowed. As a
result, interface bring-up fails unnecessarily in valid configurations.

Fix this by checking whether the scan is being requested on the same
underlying radio as the beaconing link. Only reject the scan if it targets
a link that is already beaconing and the NL80211_FEATURE_AP_SCAN is not
set. This ensures correct behavior in multi-radio environments and avoids
false rejections.

cfb58d5fc9 wifi: mac80211: simplify return value handling of cfg80211_get_radio_idx_by_chan()
In several instances where cfg80211_get_radio_idx_by_chan() is called,
redundant checks are performed across function — such as verifying if
wiphy->n_radio < 2 or if the returned index is negative. These checks are
unnecessary, as the return value can be directly compared. Moreover, the
function can be safely called even when radio-level properties are not
explicitly advertised since in such case in each call it is going to get
same error value.

Therefore, simplify the usage of this function across all such cases by
removing redundant conditions and relying on the return value directly.

e0c47c6229 wifi: mac80211: support parsing S1G TIM PVB
An S1G TIM PVB has 3 mandatory encoding modes, that being
block bitmap, single AID and OBL alongside the ability for
each encoding mode to be inverted. Introduce the ability to
parse the 3 encoding formats. The implementation specification
for the encoding formats can be found in IEEE80211-2024 9.4.2.5.
