a4cb96da7c save and restore errno in logging function 
this makes it save to use logging functions in statements that
expect errno to be unchanged

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

Setting 802.11n radio parameters is rudementary and does
not work yet.

730f110a25 [wtp] implement vendor specific elements 2016-03-24 17:15:11 +01:00
Moritz Rosenthal
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

471d1058c4 [wtp] prepare message elements for vendor element handling 
convert message element type into a struct{ vendor, type }.
Vendor will be 0 for all RFC types.

140be9b143 simplify element list handling 
Doing all the work to create a list element only to fail when we can
not decode the element is a waste of effort.
Decode the element first and only on success handle the list operations.

627a38a556 move the category setting into the element ops 
this prepares the element ops for decoding vendor
ies into seperate types.

It also makes sense to keep all information about a IE
in one place.

1436fc9e5f rename overly verbose capwap_message_elements_ops 
The struct is already conveys the scope of the operations,
repeating it in the name of ops again is redundant and
bloats the resulting source code.

Rename the opt to shorter versions.

667d7a59e7 transition to WolfSSL API 
Rename all remaining CyaSSL API references to WolfSSL.
Newer WolfSSL have significant DTLS fixes and security
improvements. Continuing to support old CyaSSL releases
would impact the perfomance of encrypted WTP sessions.

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.

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.

8937ded1d3 Improved the management of soap request/response. 
The director has the opportunity to change the configuration of AC in join
connection. The virtual interfaces which encapsulate the wifi stations is
managed dynamically by the Director.
The AC must request authorization from Director for associate a station.
