Handle encrypt of arbitarily fragmented mbuf chains: previously
we bailed if we couldn't collect the 16-bytes of data required
for an aes block cipher in 2 mbufs; now we deal with it.  While
here make space accounting signed so a sanity check does the
right thing for malformed mbuf chains.

2005-07-10 22:00  sam

nuke assert that duplicates real check

2005-07-09 18:15  sam

Change default key allocation method to do the right thing for
legacy parts (i.e. those that have 4 global key slots).  We
blindly assign unicast keys to key slot 0.  Devices that need
alternate allocation logic must override this method.

2005-07-08 17:49  sam

correct check for high priority wme traffic

Noticed by:	Ralf Assmann

2005-07-08 11:36  sam

fix another instance of the MORE_DATA bit handling for frames on the
power save queue (missed in previous commit)

Submitted by:	Bruno Randolf

2005-07-06 10:38  sam

add "pureg" mode for ap operation: reject association requests from
11b-only stations when operating in 11g

2005-07-05 20:55  sam

Fix handling of data frames queued for a station in power save mode:
don't mark the MORE_DATA bit when taking it off the ps queue, there's
no 802.11 header then; we must wait to do this at encap time so
mark the mbuf instead.

Obtained from:	Atheros

2005-07-05 20:51  sam

Fix race condition in handling node reference counts for authenticating
stations in ap mode.  Track when a node's first auth frame is
received and use this to decide whether or not to bump the refcnt.
This insures we only ever bump the refcnt once.

2005-07-05 20:31  avatar

Only update the scan entry state based on newly received frames.
This fixes duplicative BSS entries(memory leaks as well) listed in
"ifconfig dev list scan" when a station fails to associate with an AP.

2005-07-05 13:05  sam

remove auto-add of IEEE80211_KEY_GROUP; all the apps that need to
set it have been fixed

2005-07-05 12:35  sam

o when setting a wpa key, hold a ref on the bss node;
  fixes a ref cnt leak
o make unicast key handling on delete identical to set
o change legacy wep key api to reset the 802.11 state
  machine for backwards compatibility

2005-07-03 20:29  sam

when operating in ap mode, explicitly drop associated/authenticated
stations when transitioning to INIT state (e.g. as a result of
changing state at the 802.11 level)

2005-06-13 16:01  sam

revert 1.53; it breaks ibss merge

Noticed by:	Bruno Randolf

2005-06-10 16:30  sam

don't look at the wme ie in a beacon unless we negotiated use

2005-06-10 11:49  brooks

Stop embedding struct ifnet at the top of driver softcs. Instead the
struct ifnet or the layer 2 common structure it was embedded in have
been replaced with a struct ifnet pointer to be filled by a call to the
new function, if_alloc(). The layer 2 common structure is also allocated
via if_alloc() based on the interface type. It is hung off the new
struct ifnet member, if_l2com.

This change removes the size of these structures from the kernel ABI and
will allow us to better manage them as interfaces come and go.

Other changes of note:
 - Struct arpcom is no longer referenced in normal interface code.
   Instead the Ethernet address is accessed via the IFP2ENADDR() macro.
   To enforce this ac_enaddr has been renamed to _ac_enaddr.
 - The second argument to ether_ifattach is now always the mac address
   from driver private storage rather than sometimes being ac_enaddr.

2005-06-10 11:14  sam

validate the bssid for non-data frames too when operating in
adhoc/ahdemo/hostap modes

2005-06-10 11:11  sam

o fix wpa w/ wme: don't strip the QoS header on recv as tkip requires
  it; instead pass the space occupied by the header down into the
  crypto modules (except in the demic case which needs it only when
  doing int in s/w)
o while here fix defrag to strip the header from 2nd and later frames
o teach decap code how to handle 4-address frames

2005-06-10 00:04  sam

mark stations authorized during recv processing instead of doing it
as a side effect of sending an auth success frame; sending mgmt
frames should not have side effects

2005-06-09 23:42  sam

move AID implementation defines from the protocol definitions to
where they are used

2005-06-09 23:37  sam

accept diassoc frame in ASSOC state

2005-06-09 20:48  sam

pull some debug msgs up so they're seen more often

2005-06-09 20:47  sam

kick the state machine when we receive failure notice from an ap (when
operating in sta mode); this speeds up the state machine, previously
we were acting on a timeout

2005-06-09 20:43  sam

discard open auth requests in adhoc mode

2005-06-09 20:41  sam

reject open auth requests when shared key auth is configured

Obtained from:	Atheros

2005-06-09 20:40  sam

add ieee80211_send_error to encapsulate an idiom

2005-06-09 20:38  sam

o always check if ic_set_tim is !NULL before using it
o add missing call to clear tim after flushing ps q

2005-06-09 20:35  sam

mark state for protection only when operating in 11g

2005-06-09 20:33  sam

don't reject station based on the PRIVACY bit in the capabilities;
the 802.11 spec says not to

Obtained from:	Atheros

2005-06-09 20:31  sam

correct checks for rate set compatibility

2005-06-09 20:29  sam

record tstamp from beacons received in station mode when associated;
this is needed by drivers that want to resync their timers based on
the tsf of the last recv'd beacon frame

2005-06-08 23:05  sam

o collect dtim period+count from beacons in station mode so drivers
  can better program beacon timers
o leave placeholder in com structure for future ap/adhoc mode tim support

2005-06-07 18:37  sam

Change the MLME ASSOCIATE ioctl to accept either a ssid, a bssid,
or a bssid+ssid. This is needed for later versions of wpa_supplicant
and for forthcoming addons to wpa_supplicant.

Note this is an api change and applications must be rebuilt.

2005-06-07 18:31  sam

Don't clock the state machine in various cases when roaming is set
to manual; this helps keep wpa_supplicant in sync.

2005-06-06 19:08  sam

WPA/802.11i interoperability fixes:
o only include capabilities word in the WPA ie when non-zero and
  not preauth
o always include the capabilities in the RSN ie

Obtained from:	Atheros

2005-06-05 23:04  sam

add force flag to enmic/demic crypto api for use in xmit fragmentation
and h/w mic verification
