wifi: mac80211: tests: add tests for ieee80211_determine_chan_mode

2025-02-11T10:59:07+00:00

Add a few tests for ieee80211_determine_chan_mode that check that
mac80211 will not try to connect to an AP if an advertised basic rate is
not supported.

2025-01-13T14:26:45+00:00

Some functions that should be tested may expect an sdata object that is
configured to a basic degree. Add setup code to create such an object
for use by tests.

module: Convert symbol namespace to string literal

2024-12-02T19:34:44+00:00

Clean up the existing export namespace code along the same lines of
commit 33def8498fdd ("treewide: Convert macro and uses of __section(foo)
to __section("foo")") and for the same reason, it is not desired for the
namespace argument to be a macro expansion itself.

wifi: mac80211: pass parsed TPE data to drivers

2024-05-23T08:35:04+00:00

Instead of passing the full TPE elements, in all their glory
and mixed up data formats for HE backward compatibility, parse
them fully into the right values, and pass that to the drivers.

Also introduce proper validation already in mac80211, so that
drivers don't need to do it, and parse the EHT portions.

The code now passes the values in the right order according to
the channel used by an interface, which could also be a subset
of the data advertised by the AP, if we couldn't connect with
the full bandwidth (for whatever reason.)

Also add kunit tests for the more complicated bits of it.

wifi: mac80211: clean up connection process

2024-02-08T11:58:26+00:00

Rewrite the station-side connection handling. The connection
flags (IEEE80211_DISABLE_*) are rather confusing, and they're
not always maintained well. Additionally, for wider-bandwidth
OFDMA support we need to know the precise bandwidth of the AP,
which is currently somewhat difficult.

Rewrite this to have a 'mode' (S1G/legacy/HT/...) and a limit
on the bandwidth. This is not entirely clean because some of
those modes aren't completely sequenced (as this assumes in
some places), e.g. VHT doesn't exist on 2.4 GHz, but HE does.
However, it still simplifies things and gives us a good idea
what we're operating as, so we can parse elements accordingly
etc.

This leaves a FIXME for puncturing, this is addressed in a
later patch.
