Andreas Schultz 4d56938321 reindent ieee80211_retrieve_information_elements_position 2016-03-03 15:27:29 +01:00
Andreas Schultz d68bc01d00 change supportedrates config setting to the actual MBit value 
supportedrates is now a list instead on an array and float values
(e.g. 5.5) are permited.

Andreas Schultz 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.

Andreas Schultz e4a5abba65 add support for CAPWAP IEEE 802.11 Information Element 2016-02-29 14:32:02 +01:00
Andreas Schultz 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.

Andreas Schultz b80073b756 inject 802.11 frames through the normal device queue 2016-02-25 12:39:19 +01:00
Andreas Schultz 0c19932b58 send 802.3 frames through the normal device TX path 
Injecting 802.11 frames underneath the device logic bypasses
the queue logik and leads to delay. Pass 802.3 frames through
the normal device TX chain.

This has the added benefit that AF_PACKET sockets (e.g. tcpdump)
see the send frames.

Andreas Schultz f3119eec8d rework kernel socket handling to use udp tunnel infrastructure 
Reimplmenting what is already there doesn't make sense. Switch
to the existing and UDP tunnel support code and handle the data
channel as a connected UDP socket

Andreas Schultz cc5b38f322 impelment station binding to wlanid 
* add a kernel bash hash list to track station to
  radio and wlan id binding
* enforce binding on recv
* configure binding through netlink interface from
  WTP process

Andreas Schultz a6d0efe91a wtp: rework kernel socket handling 
Switch to a connected UDP kernel socket. Comparing the
local and remote IPs is no longer required and handling
different IP versions and UDP types is automatic.

The WTP logic needs to reopen the socket on demand now.

Andreas Schultz c71a9db6ed remove IEEE 802.11 WTP Radio Information from responses 
RFC 5416 does require IEEE 802.11 WTP Radio Information for
Discovery and Join Response Messages in Chapter 5. However
Chapter 6.25 indicates that this IE should only be included
in the request messages.

Andreas Schultz 385832a010 start with network namespace support 
This is incomplete. There are several places left where a global
variable is used (e.g. there can only be one AC session).
