You can use nl28011 and register for netlink multicast messages which
broadcast device state changes like the ones you mentioned. These come
in on iw via event.c, see print_event() and see the case statements
for NL80211_CMD_ASSOCIATE, NL80211_CMD_DEAUTHENTICATE,
NL80211_CMD_DISASSOCIATE, etc, you even get reason codes parsed for
you too.
Ahhh, that is the kind of thing I'm looking for. I'll check out that
code in detail tomorrow.
Keep in mind though that not all drivers can give you the difference
between AUTH and ASSOC, and will ONLY report "CONNECTED" events. This is
those drivers that do roaming and all that in firmware rather than in
mac80211. Therefore, generally speaking, you cannot get the states
you're after.
FWIW I think he's on ath9k.
My real goal is to support lots (128+ hopefully) of
virtual stations on ath5k and ath9k. We had this working
for ath5k in .31 kernel, but too much has changed to make it
a straight-forward upgrade to .34.
As soon as I can get the management logic fixed up (ie, libnl
to listen to wireless events, etc), we should be able to start
on the virtualization work in earnest.
Thanks,
Ben
