 Hi!
 
 At $WORK, we use 802.1X to authenticate computers on the network.
 Authenticated computers receive a lease in the 192.168.X.X/24 network.
 Unauthenticated ones receive a lease in the 172.16.X.X/24 network.
 
 Today, I upgraded one computer running 10-CURRENT to latest HEAD and it
 seems that the interface is brought up to early now: dhclient is started
 before wpa_supplicant finishes. This was working perfectly before the
 upgrade.
 
 I don't have logs of the working case, but here are the logs of the
 non-working one:

 Was I lucky with wpa_supplicant/dhclient timing? Or is there a real
 issue here?
 

CC'ed wireless@, that's probably the proper list for the issue.

I think you were lucky.

dhclient shouldn't start running until wpa_supplicant has completed
authentication.

I think you're right.

It works perfectly on FreeBSD 9.1, because wpa_supplicant finishes the
auth process really quickly, ie. before dhclient receives an answer from
dhcpd from the unauthenticated network:

Jul 29 15:39:46 - kernel: bge0: link state changed to UP
Jul 29 15:39:46 - dhclient[46150]: DHCPREQUEST on bge0 to
255.255.255.255 port 67
Jul 29 15:39:47 - wpa_supplicant[46119]: CTRL-EVENT-EAP-STARTED EAP
authentication started
...
Jul 29 15:39:47 - wpa_supplicant[46119]: CTRL-EVENT-EAP-SUCCESS EAP
authentication completed successfully
Jul 29 15:39:48 - dhclient[46150]: DHCPREQUEST on bge0 to
255.255.255.255 port 67
Jul 29 15:39:48 - dhclient[46150]: DHCPACK from 192.168.200.224
Jul 29 15:39:48 - dhclient: New IP Address (bge0): 192.168.200.91
Jul 29 15:39:48 - dhclient: New Subnet Mask (bge0): 255.255.255.0
Jul 29 15:39:48 - dhclient: New Broadcast Address (bge0): 192.168.200.255
Jul 29 15:39:48 - dhclient: New Routers (bge0): 192.168.200.254

On -CURRENT, wpa_supplicant is started more than 10 seconds after the
interface is UP and dhclient sent its request
(http://pastebin.com/ZHcbHLQZ). Therefore, a lease from the
unauthenticated network arrives first. It was working with a previous
-CURRENT (buildworld from around April if memory serves).

 dhclient shouldn't start running until wpa_supplicant has completed
 authentication.

Damn, I always thought it worked this way on FreeBSD and happily laughed
at Linux co-workers who use some kind of rc.local script to work
around this issue :-) In fact, we're all in the same boat!

I may take a look at the issue. I guess the place to fix this is in the
rc scripts. Does someone have a hint?

... wait, so the new version of wpa_supplicant takes 10 seconds to
even start doing anything?

Or are the rc scripts to blame?
