4a27563b5a eapol: Fix key-IV check in EAPOL-Key verification

445ad55796 eapol: Start a handshake timer 
We start a timer.  This handles the case that the Authenticator does
not send us the first message of the 4-way handshake, or disappears
before sending us the 3rd message.

6b84e0da1f eapol: Rename aa_addr 
The use of aa_addr was redundant.  Use 'AA' instead.  802.11 defines
'AA' as 'Authenticator Address'.
 2015-03-19 23:57:36 -05:00
Denis Kenzior
b871d904d5 eapol: Rename sta_addr 
The use of sta_addr made no sense.  Instead, use the terminology from

12d529eddb eapol: Rearrange data structure members 
The order follows the rough order of initialization, as information
becomes available from the calling code or via steps of the 4-way
handshake.

41e82fba77 eapol: Optimize out rsne sizes 
The RSN IEs contain the sizes of the element inside the data, so it is
not necessary to carry a dedicated size element.

8f946c0cdc eapol: Change function signatures 
The frame which comes in is an EAPoL-key frame, thus changing the name
accordingly (as well as the parameter names).

Also, returning the cast pointer instead of a boolean is easier to
use as there won't be any need to perform the cast ourselves afterward
