Re: AirPort Extreme version 3.1 & compatibility

at line 522 in wi_hostap.c the problem starts...and yes it also seems 
to have something to do with shared auth.  Now it send the request as 
type open, but puts some challenge in there anyway.  The take_tlv() 
comes back with a negative number (have not dove in there yet, it's 
pretty simple), and the association fails.  When I comment out the 
challenge processing everything works.  The last three lines are what 
to take out, I'm sure this will break things but perhaps nothing that 
was not already broken in this driver already.  I'm moving all my APs 
over to -current now.  Peterson is testing with -stable which may be a 
safer bet for others.

         /* Break open packet. */
         algo = take_hword(&pkt, &len);
         seq = take_hword(&pkt, &len);
         status = take_hword(&pkt, &len);
         challenge_len = 0;
         if (len > 0 && (challenge_len = take_tlv(&pkt, &len,
             IEEE80211_ELEMID_CHALLENGE, challenge, sizeof(challenge))) 
< 0)
                 return;

Cheers,
Cliff
