mac80211: do not scan and monitor connection in parallel

2012-04-13T18:31:49+00:00

Before we send probes in connection monitoring we check if scan is not
pending. But we do that check without locking. Fix that and also do not
start scan if connection monitoring is in progress.

mac80211: redesign auth/assoc

2012-02-06T19:50:37+00:00

This is the second part of the auth/assoc redesign,
the mac80211 part. This moves the auth/assoc code
out of the work abstraction and into the MLME, so
that we don't flip channels all the time etc.

The only downside is that when we are associated,
we need to drop the association in order to create
a connection to another AP, but for most drivers
this is actually desirable and the ability to do
was never used by any applications. If we want to
implement resource reservation with FT-OTA, we'd
probably best do it with explicit R-O-C in wpa_s.

mac80211: In IBSS the DA field of auth frames is different from BSSID

2012-01-24T19:08:39+00:00

In case of authentication frame exchange between two IBSS STAs, the
DA field must contain the destinatioin address (instead of the BSSID).

mac80211: revert on-channel work optimisations

2011-11-30T20:08:31+00:00

The on-channel work optimisations have caused a
number of issues, and the code is unfortunately
very complex and almost impossible to follow.
Instead of attempting to put in more workarounds
let's just remove those optimisations, we can
work on them again later, after we change the
whole auth/assoc design.

This should fix rate_control_send_low() warnings,
see RH bug 731365.

mac80211: Support ht-cap over-rides.

2011-11-21T21:22:06+00:00

This implements ht-cap over-rides for mac80211 drivers.
HT may be disabled, making an /a/b/g/n station act like an
a/b/g station.  HT40 may be disabled forcing the station to
be HT20 even if the AP and local hardware support HT40.

MAX-AMSDU may be disabled.
AMPDU-Density may be increased.
AMPDU-Factor may be decreased.

This has been successfully tested with ath9k using patched
wpa_supplicant and iw.

mac80211: simplify ieee80211_work_work

2011-11-09T21:01:01+00:00

Since local->tmp_channel is always NULL in one branch, some code paths
will newer be taken in that branch, so remove them.

mac80211: Add HT helper functions

2011-11-08T20:54:32+00:00

Some refactoring for IBSS HT.

Move HT info and capability IEs building code into separate functions.

Add function to get the channel type from an HT info IE.

mac80211: config hw when going back on-channel

2011-11-02T19:23:11+00:00

When going back on-channel, we should reconfigure
the hw iff the hardware is not already configured
to the operational channel.
