wifi: mac80211: fragment per STA profile correctly

2023-06-12T07:52:52+00:00

When fragmenting the ML per STA profile, the element ID should be
IEEE80211_MLE_SUBELEM_PER_STA_PROFILE rather than WLAN_EID_FRAGMENT.

Change the helper function to take the to be used element ID and pass
the appropriate value for each of the fragmentation levels.

wifi: mac80211: consider reserved chanctx for mindef

2023-05-16T17:25:43+00:00

When a chanctx is reserved for a new vif and we recalculate
the minimal definition for it, we need to consider the new
interface it's being reserved for before we assign it, so it
can be used directly with the correct min channel width.

Fix the code to - optionally - consider that, and use that
option just before doing the reassignment.

Also, when considering channel context reservations, we
should only consider the one link we're currently working with.
Change the boolean argument to a link pointer to do that.

wifi: mac80211: enable EHT mesh support

2023-03-31T09:09:59+00:00

Similar to AP beacon, this enables the basic mesh EHT mode, including
EHT operation IE and the fixed field of EHT operation information IE.
As for the optional part (i.e. preamble puncturing bitmap) will be
added in future patch.

wifi: mac80211: Serialize ieee80211_handle_wake_tx_queue()

2023-03-15T12:42:43+00:00

ieee80211_handle_wake_tx_queue must not run concurrent multiple times.
It calls ieee80211_txq_schedule_start() and the drivers migrated to iTXQ
do not expect overlapping drv_tx() calls.

This fixes 'c850e31f79f0 ("wifi: mac80211: add internal handler for
wake_tx_queue")', which introduced ieee80211_handle_wake_tx_queue.
Drivers started to use it with 'a790cc3a4fad ("wifi: mac80211: add
wake_tx_queue callback to drivers")'.
But only after fixing an independent bug with
'4444bc2116ae ("wifi: mac80211: Proper mark iTXQs for resumption")'
problematic concurrent calls really happened and exposed the initial
issue.

wifi: mac80211: Drop stations iterator where the iterator function may sleep

2023-01-12T10:05:51+00:00

This reverts commit acb99b9b2a08f ("mac80211: Add stations iterator
where the iterator function may sleep"). A different approach was found
for the rtw88 driver where most of the problematic locks were converted
to a driver-local mutex. Drop ieee80211_iterate_stations() because there
are no users of that function.
