f1871abd27 wifi: mac80211: Add getter functions for vif MLD state
As a preparation to support disabled/dormant links, add the
following function:

- ieee80211_vif_usable_links(): returns the bitmap of the links
  that can be activated. Use this function in all the places that
  the bitmap of the usable links is needed.

- ieee80211_vif_is_mld(): returns true iff the vif is an MLD.
  Use this function in all the places where an indication that the
  connection is a MLD is needed.

556f16b834 wifi: mac80211: fix CSA processing while scanning
The channel switch parsing code would simply return if a scan is
in-progress. Supposedly, this was because channel switch announcements
from other APs should be ignored.

For the beacon case, the function is already only called if we are
associated with the sender. For the action frame cases, add the
appropriate check whether the frame is coming from the AP we are
associated with. Finally, drop the scanning check from
ieee80211_sta_process_chanswitch.

68c228557d wifi: mac80211: mlme: fix non-inheritence element
There were two bugs when creating the non-inheritence
element:
 1) 'at_extension' needs to be declared outside the loop,
    otherwise the value resets every iteration and we
    can never really switch properly
 2) 'added' never got set to true, so we always cut off
    the extension element again at the end of the function

This shows another issue that we might add a list but no
extension list, but we need to make the extension list a
zero-length one in that case.

Fix all these issues. While at it, add a comment explaining
the trim.

logic, extend 'struct ieee802_11_elems' to hold a scratch buffer,
which is used for the defragmentation. Once an element is

092197f1f4 wifi: mac80211: remove/avoid misleading prints
At some point a few kernel debug prints started appearing which
indicated something was sending invalid IEs:

"bad VHT capabilities, disabling VHT"
"Invalid HE elem, Disable HE"

Turns out these were being printed because the local hardware
supported HE/VHT but the peer/AP did not. Bad/invalid indicates,
to me at least, that the IE is in some way malformed, not missing.

For the HE print (ieee80211_verify_peer_he_mcs_support) it will
now silently fail if the HE capability element is missing (still
prints if the element size is wrong).

For the VHT print, it has been removed completely and will silently
set the DISABLE_VHT flag which is consistent with how DISABLE_HT
is set.

6546646a7f wifi: mac80211: mlme: Fix double unlock on assoc success handling
Commit 6911458dc428 ("wifi: mac80211: mlme: refactor assoc success
handling") moved the per-link setup out of ieee80211_assoc_success() into a
new function ieee80211_assoc_config_link() but missed to remove the unlock
of 'sta_mtx' in case of HE capability/operation missing on HE AP, which
leads to a double unlock:

ieee80211_assoc_success() {
    ...
    ieee80211_assoc_config_link() {
        ...
        if (!(link->u.mgd.conn_flags & IEEE80211_CONN_DISABLE_HE) &&
            (!elems->he_cap || !elems->he_operation)) {
            mutex_unlock(&sdata->local->sta_mtx);
            ...
        }
        ...
    }
    ...
    mutex_unlock(&sdata->local->sta_mtx);
    ...
}

883b8dc1a8 wifi: mac80211: mlme: Fix missing unlock on beacon RX
Commit 98b0b467466c ("wifi: mac80211: mlme: use correct link_sta")
switched to link station instead of deflink and added some checks to do
that, which are done with the 'sta_mtx' mutex held. However, the error
path of these checks does not unlock 'sta_mtx' before returning.

efe9c2bfd1 wifi: mac80211: isolate driver from inactive links
In order to let the driver select active links and properly
make multi-link connections, as a first step isolate the
driver from inactive links, and set the active links to be
only the association link for client-side interfaces. For
AP side nothing changes since APs always have to have all
their links active.

To simplify things, update the for_each_sta_active_link()
API to include the appropriate vif pointer.

This also implies not allocating a chanctx for an inactive
link, which requires a few more changes.

Since we now no longer try to program multiple links to the
driver, remove the check in the MLME code.

acdc3e4788 wifi: mac80211: mlme: assign link address correctly
Right now, we assign the link address only after we add
the link to the driver, which is quite obviously wrong.
It happens to work in many cases because it gets updated
immediately, and then link_conf updates may update it,
but it's clearly not really right.

Set the link address during ieee80211_mgd_setup_link()
so it's set before telling the driver about the link.

69371801f9 wifi: mac80211: fix locking in auth/assoc timeout
If we hit an authentication or association timeout, we only
release the chanctx for the deflink, and the other link(s)
are released later by ieee80211_vif_set_links(), but we're
not locking this correctly.

Fix the locking here while releasing the channels and links.
