4ece9b0fbc wifi: mac80211: use deflink and fix typo in link ID check
[ Upstream commit e10322810c ]

This does not change anything effectively, but it is closer to what the
code is trying to achieve here. i.e. select the link data if it is an
MLD and fall back to using the deflink otherwise.

413dafc817 wifi: mac80211: only call drv_sta_rc_update for uploaded stations
When a station has not been uploaded yet, receiving SMPS or channel width
notification action frames can lead to rate_control_rate_update calling
drv_sta_rc_update with uninitialized driver private data.
Fix this by adding a missing check for sta->uploaded.

c98d8836b8 wifi: mac80211: reload info pointer in ieee80211_tx_dequeue()
This pointer can change here since the SKB can change, so we
actually later open-coded IEEE80211_SKB_CB() again. Reload
the pointer where needed, so the monitor-mode case using it
gets fixed, and then use info-> later as well.

62a6183c13 wifi: mac80211: accept broadcast probe responses on 6 GHz
On the 6 GHz band, probe responses are sent as broadcast to
optimise medium usage. However, without OCE configuration
we weren't accepting them, which is wrong, even if wpa_s is
by default enabling OCE. Accept them without the OCE config
as well.

interface type without taking the interface down, but still will

to also recreate the driver's files, if it is indeed from a type

35e2385dbe wifi: mac80211: improve CSA/ECSA connection refusal
As mentioned in the previous commit, we pretty quickly found
that some APs have ECSA elements stuck in their probe response,
so using that to not attempt to connect while CSA is happening
we never connect to such an AP.

Improve this situation by checking more carefully and ignoring
the ECSA if cfg80211 has previously detected the ECSA element
being stuck in the probe response.

Additionally, allow connecting to an AP that's switching to a
channel it's already using, unless it's using quiet mode. In
this case, we may just have to adjust bandwidth later. If it's
actually switching channels, it's better not to try to connect
in the middle of that.

option KERNEL_6_2 does not exist in the tree. This dependency is used for
handling backporting to restrict the option to certain kernels but this
really should not be carried around the mainline kernel tree.

Clean up this needless dependency on the non-existing option KERNEL_6_2.

e993af2ed2 wifi: mac80211: add a driver callback to check active_links
During ieee80211_set_active_links() we do (among the others):
1. Call drv_change_vif_links() with both old_active and new_active
2. Unassign the chanctx for the removed link(s) (if any)
3. Assign chanctx to the added link(s) (if any)
4. Call drv_change_vif_links() with the new_active links bitmap

The problem here is that during step #1 the driver doesn't know whether
we will activate multiple links simultaneously or are just doing a link
switch, so it can't check there if multiple links are supported/enabled.
(Some of the drivers might enable/disable this option dynamically)

And during step #3, in which the driver already knows that,
returning an error code (for example when multiple links are not
supported or disabled), will cause a warning, and we will still complete
the transition to the new_active links.
(It is hard to undo things in that stage, since we released channels etc.)

Therefore add a driver callback to check if the desired new_active links
will be supported by the driver or not. This callback will be called
in the beginning of ieee80211_set_active_links() so we won't do anything
before we are sure it is supported.

e62c0fcc0e wifi: mac80211: allow 64-bit radiotap timestamps
When reporting the radiotap timestamp, the mactime field is
usually unused, we take the data from the device_timestamp.
However, there can be cases where the radiotap timestamp is
better reported as a 64-bit value, so since the mactime is
free, add a flag to support using the mactime as a 64-bit
radiotap timestamp.

b133fdf07d wifi: mac80211: Skip association timeout update after comeback rejection
It is possible for the TX status report for the (Re)Association Request
frame to be delayed long enough for the AP's (Re)Association Response
frame to be received and processed before it. If that were to happen for
a case where the AP rejects the association with indication to come back
later, the association timeout and retry state should not be modified
anymore with the TX status information that would be processed after
this. Updating the association timeout in such a reverse order of events
could result in shortening the timeouts for the association comeback
mechanism and that could result in the association failing.

Track whether we have already processed association rejection with
comeback time and if so, skip the timeout and retry update on any
following TX status report.

[Analysis]
It is inappropriate to make a link configuration change judgment on an
non-existent and non new link.

[Fix]
Quickly exit when there is a existent link and the link configuration has not
changed.

4ded3bfe1d wifi: mac80211: use wiphy locked debugfs for sdata/link
The debugfs files for netdevs (sdata) and links are removed
with the wiphy mutex held, which may deadlock. Use the new
wiphy locked debugfs to avoid that.
