mac80211: add missing channel context release

2013-09-08T05:09:59+00:00

commit 2a3ba63c235fdcd37f6451bdf4a0c7865a3930cf upstream.

IBSS needs to release the channel context when leaving
but I evidently missed that. Fix it.

mac80211: parse VHT channel switch IEs

2013-04-16T13:29:45+00:00

VHT introduces multiple IEs that need to be parsed for a
wide bandwidth channel switch. Two are (currently) needed
in mac80211:
 * wide bandwidth channel switch element
 * channel switch wrapper element

The former is contained in the latter for beacons and probe
responses, but not for the spectrum management action frames
so the IE parser needs a new argument to differentiate them.

mac80211: provide SSID in IBSS mode

2013-04-10T18:24:18+00:00

Some drivers need SSID in AP and IBSS mode. AP SSID is provided
through BSS_CHANGED_SSID notification. There was no easy way to
do the same for IBSS. In IBSS mode SSID is known but was not
stored in BSS configuration. Extend the AP-mode functionality
to also work in IBSS mode.

mac80211: check DSSS params IE length in parser

2013-04-08T07:16:56+00:00

It's always just one byte, so check for that and
remove the length field from the parser struct.

mac80211: ibss: use beacon_data struct for beacon and probe response

2013-03-25T13:42:41+00:00

Instead of having an SKB all the time, use a beacon_data struct
with just the information required. This also allows removing a
synchronize_rcu() and using kfree_rcu() instead.

mac80211: ibss: disable beaconing before freeing beacon

2013-03-25T13:42:39+00:00

If we don't disable beaconing, the driver might attempt
to continue, but would fail to request a beacon. That's
strange, so disable beaconing first.

mac80211: cleanup suspend/resume on ibss mode

2013-03-06T15:35:57+00:00

Remove not used any longer suspend/resume code.

mac80211: stop toggling IEEE80211_HT_CAP_SUP_WIDTH_20_40

2013-02-15T08:41:30+00:00

For VHT, many more bandwidth changes are possible. As a first
step, stop toggling the IEEE80211_HT_CAP_SUP_WIDTH_20_40 flag
in the HT capabilities and instead introduce a bandwidth field
indicating the currently usable bandwidth to transmit to the
station. Of course, make all drivers use it.

To achieve this, make ieee80211_ht_cap_ie_to_sta_ht_cap() get
the station as an argument, rather than the new capabilities,
so it can set up the new bandwidth field.

If the station is a VHT station and VHT bandwidth is in use,
also set the bandwidth accordingly.

Doing this allows us to get rid of the supports_40mhz flag as
the HT capabilities now reflect the true capability instead of
the current setting.

While at it, also fix ieee80211_ht_cap_ie_to_sta_ht_cap() to not
ignore HT cap overrides when MCS TX isn't supported (not that it
really happens...)

mac80211: simplify idle handling

2013-02-11T17:45:01+00:00

Now that we have channel contexts, idle is (pretty
much) equivalent to not having a channel context.
Change the code to use this relation so that there
no longer is a need for a lot of idle recalculate
calls everywhere.

cfg80211: move TSF into IEs

2013-02-11T17:44:59+00:00

While technically the TSF isn't an IE, it can be
necessary to distinguish between the TSF from a
beacon and a probe response, in particular in
order to know the next DTIM TBTT, as not all APs
are spec compliant wrt. TSF==0 being a DTIM TBTT
and thus the DTIM count needs to be taken into
account as well.

To allow this, move the TSF into the IE struct
so it can be known whence it came.
