f7e3ba846f rework station reuse in deauth logic to make it clearer 
The hidden station clean logic in wifi_wlan_deauthentication_station
obfuscated the station object reuse in the only caller that actually
used it.

146939a716 delete station from kmod before reusing it 
The AC is supposed to react to WiFi Authorization requests
with Add Station messages. Such an Add Station will fail
with the station is already present in the data path.

A Authorization request for a station that the WTP already
in authorized state means that the station lost its assoziation
without the WTP detecting that. So, clearing it from the data
path seems to be appropriate.

84859e20c4 also clear the local control port when resetting the WTP state 
Without reseting the port, the new control socket will be
bound to the same port as the old one.

32e9567f7b rework bssid handling and stop all used bssids when leaving RUN 
Instead of haing a pool of unsused BSS Id's and a list of active
BSS's (wlans), use a single array and only mark the BSS Id as used
or unused.

When leaving RUN state, release (stop) all used BSS.

2109c62b80 implement basic 802.11n support 
Add suport to enable 80211n support on the BSS and set
station parameters through the "Add Station" procedure.

7b9f515bd7 If there is no DNS available on system start the capwap-wtp will stop while evaluating the configuration. I fixed that by checking if the address was yet translated on every address access. If not a DNS request is started before continuing. 2016-03-24 07:09:29 +01:00

8dc30ae3c4 rework socket and discovery handling 
Swtich sockets to connected when talking to a specific AC. Use
unconnected UDP sockets only during DISCOVERY.

In JOIN, we need send our local address. The old, routing table
based local address discovery is broken for many reasons (VRF,
policy routing, ...). With a connected socket, we can the same
information with a simple getsockname.

During DISCOVERY we are talking to all potential AC's at once.
So using an unconnected socket makes still sense.

9fee37a994 rework wifi type and rate logic 
Hard coding basic rates is wrong. Each Wifi types does expect
some default basic rates. However those rates are not set in
stone and the AC is permited to set then to whatever it deems
ok. This might prevent client from connecting, but it still is
the AC decission to do so.

This is first step towards a more flexible basic rate handling.
