====================
wireless-next patches for v6.4

Most likely the last -next pull request for v6.4. We have changes all
over. rtw88 now supports SDIO bus and iwlwifi continues to work on
Wi-Fi 7 support. Not much stack changes this time.

Major changes:

cfg80211/mac80211
 - fix some Fine Time Measurement (FTM) frames not being bufferable
 - flush frames before key removal to avoid potential unencrypted
   transmission depending on the hardware design

iwlwifi
 - preparation for Wi-Fi 7 EHT and multi-link support

rtw88
 - SDIO bus support
 - RTL8822BS, RTL8822CS and RTL8821CS SDIO chipset support

rtw89
 - framework firmware backwards compatibility

brcmfmac
 - Cypress 43439 SDIO support

mt76
 - mt7921 P2P support
 - mt7996 mesh A-MSDU support
 - mt7996 EHT support
 - mt7996 coredump support

wcn36xx
 - support for pronto v3 hardware

ath11k
 - PCIe DeviceTree bindings
 - WCN6750: enable SAR support

ath10k
 - convert DeviceTree bindings to YAML

mac80211: use the new drop reasons infrastructure

2023-04-21T03:20:49+00:00

It can be really hard to analyse or debug why packets are
going missing in mac80211, so add the needed infrastructure
to use use the new per-subsystem drop reasons.

We actually use two drop reason subsystems here because of
the different handling of frames that are dropped but still
go to monitor for old versions of hostapd, and those that
are just completely unusable (e.g. crypto failed.)

Annotate a few reasons here just to illustrate this, we'll
need to go through and annotate more of them later.

wifi: mac80211: remove return value check of debugfs_create_dir()

2023-04-20T09:46:07+00:00

Smatch complains that:
debugfs_hw_add() warn: 'statsd' is an error pointer or valid

Debugfs checks are generally not supposed to be checked for errors
and it is not necessary here.

Just delete the dead code.

wifi: mac80211: remove ieee80211_tx_status_8023

2023-04-18T12:48:01+00:00

It is unused and should not be used. In order to avoid limitations in
4-address mode, the driver should always use ieee80211_tx_status_ext for
802.3 frames with a valid sta pointer.

wifi: mac80211: add flush_sta method

2023-04-13T14:32:31+00:00

Some drivers like iwlwifi might have per-STA queues, so we
may want to flush/drop just those queues rather than all
when removing a station. Add a separate method for that.

wifi: mac80211: flush queues on STA removal

2023-04-13T14:32:22+00:00

When we remove a station, we first make it unreachable,
then we (must) remove its keys, and then remove the
station itself. Depending on the hardware design, if
we have hardware crypto at all, frames still sitting
on hardware queues may then be transmitted without a
valid key, possibly unencrypted or with a fixed key.

Fix this by flushing the queues when removing stations
so this cannot happen.

wifi: ieee80211: correctly mark FTM frames non-bufferable

2023-04-13T14:32:02+00:00

The checks of whether or not a frame is bufferable were not
taking into account that some action frames aren't, such as
FTM. Check this, which requires some changes to the function
ieee80211_is_bufferable_mmpdu() since we need the whole skb
for the checks now.

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.
