wifi: mac80211: fix BSS_CHANGED_UNSOL_BCAST_PROBE_RESP

2024-07-11T10:51:08+00:00

[ Upstream commit 816c6bec09ed5b90a58a1e12d5a606c5b6e23f47 ]

Fix the definition of BSS_CHANGED_UNSOL_BCAST_PROBE_RESP so that
not all higher bits get set, 1<<31 is a signed variable, so when
we do

  u64 changed = BSS_CHANGED_UNSOL_BCAST_PROBE_RESP;

we get sign expansion, so the value is 0xffff'ffff'8000'0000 and
that's clearly not desired. Use BIT_ULL() to make it unsigned as
well as the right type for the change flags.

wifi: mac80211: don't use rate mask for scanning

2024-04-08T18:11:34+00:00

The rate mask is intended for use during operation, and
can be set to only have masks for the currently active
band. As such, it cannot be used for scanning which can
be on other bands as well.

Simply ignore the rate masks during scanning to avoid
warnings from incorrect settings.

wifi: mac80211: introduce a feature flag for quiet in CSA

2024-03-04T13:33:58+00:00

When doing CSA in multi-link, there really isn't a need to
stop transmissions entirely. Add a feature flag for drivers
to indicate they can handle quiet in CSA (be it by parsing
themselves, or by implementing drv_pre_channel_switch()),
to make that possible.

Also clean up the csa_block_tx handling: it clearly cannot
handle multi-link due to the way queues are stopped, move
it to the sdata. Drivers should be doing it themselves for
working properly during CSA in MLO anyway. Also rename it
to indicate that it reflects TX was blocked at mac80211.

wifi: mac80211: pass link_id to channel switch ops

For CSA to work correctly in multi-link scenarios, pass
the link_id to the relevant callbacks.

While at it, unify/deduplicate the tracing for them.

wifi: mac80211: add ieee80211_vif_link_active() helper

2024-03-04T13:32:53+00:00

We sometimes need to check if a link is active, and this
is complicated by the fact that active_links has no bits
set when the vif isn't (acting as) an MLD. Add a small
new helper ieee80211_vif_link_active() to make that a bit
easier, and use it in a few places.

wifi: mac80211: check beacon countdown is complete on per link basis

2024-02-21T14:19:03+00:00

Currently, function to check if beacon countdown is complete uses deflink
to fetch the beacon and check the counter. However, with MLO, there is
a need to check the counter for the beacon in a particular link.

Add support to use link_id in order to fetch the beacon from a particular
link data.
