When regulatory information changes our HT behavior (e.g,
when we get a country code from the AP we have just associated
with), we should use this information to change the power with
which we transmit, and what channels we transmit. Sometimes
the channel parameters we derive from regulatory information
contradicts the parameters we used in association. For example,
we could have associated specifying HT40, but the regulatory
rules we apply may forbid HT40 operation.
In the situation above, we should reconfigure ourselves to
transmit in HT20 only, however it makes no sense for us to
disable receive in HT40, since if we associated with these
parameters, the AP has every reason to expect we can and
will receive packets this way. The code in mac80211 does
not have the capability of sending the appropriate action
frames to signal a change in HT behaviour so the AP has
no clue we can no longer receive frames encoded this way.
In some broken AP implementations, this can leave us
effectively deaf if the AP never retries in lower HT rates.
This change breaks up the channel_type parameter in the
ieee80211_enable_ht function into a separate receive and
transmit part. It honors the channel flags set by regulatory
in order to configure the rate control algorithm, but uses
the capability flags to configure the channel on the radio,
since these were used in association to set the AP's transmit
rate.

This value is not really very useful by itself,
yet some drivers (including iwlwifi until I can

rename it to "last_tsf" to indicate the meaning

I suspect the value may become useful combined

The authentication and association handshake
already happens in the context of the new BSS,
and the basic rates are needed at least for
the ACK response frame to the authentication

basic rates should already be configured into

As we've discussed, we want to avoid channel changes
while associated. While the part when we actually
associate needs a bit more work, the bit that happens
on disassociating can be changed quite easily. Move
the channel type change later in the disassociate
process to set the channel only after the driver was
told that it's now disassociated.
As the driver could expect powersave to be enabled
only when associated, this thus results in splitting
the config call, but overall what happens makes more
sense this way.

While setting up or tearing down a BA session mac80211 is buffering
pending frames for the according TID. However, there's currently no
limit on how many frames are buffered possibly leading to an out-of-
memory situation. This can happen on systems with little memory when
the CPU is fully loaded since the BA session work is executed in
process context while frames can still come via softirq.
Apply a limitation to the TIDs pending queue to avoid consuming
too much memory in this situation.

mac80211 is lenient with respect to reception of corrupted beacons.
Even if the frame is corrupted as a whole, the available IE elements
are still passed back and accepted, sometimes replacing legitimate
data. It is unknown to what extent this "feature" is made use of,
but it is clear that in some cases, this is detrimental. One such
case is reported in http://crosbug.com/26832 where an AP corrupts
its beacons but not its probe responses.
One approach would be to completely reject frames with invaid data
(for example, if the last tag extends beyond the end of the enclosing
PDU). The enclosed approach is much more conservative: we simply
prevent later IEs from overwriting the state from previous ones.
This approach hopes that there might be some salient data in the
IE stream before the corruption, and seeks to at least prevent that
data from being overwritten. This approach will fix the case above.
Further, we flag element structures that contain data we think might
be corrupted, so that as we fill the mac80211 BSS structure, we try
not to replace data from an un-corrupted probe response with that
of a corrupted beacon, for example.
Short of any statistics gathering in the various forms of AP breakage,
it's not possible to ascertain the side effects of more stringent
discarding of data.

The association sequence looks (roughly) like
this now:
* set BSSID
* set station to EXIST state
* send auth
* set station to AUTH state
* send assoc
* set station to ASSOC state
* set BSS info to associated
In contrast, the deauth/disassoc sequence is
the other way around:
* clear BSSID/BSS info state
* remove station
* send deauth/disassoc
(in some cases the last two steps are reversed.)
This patch encodes the entire sequence in the
ieee80211_set_disassoc() function and changes
it to be like this, for good measure with an
explicit flush:
* send deauth/disassoc
* flush
* remove station
* clear BSSID/BSS info state
At least iwlwifi gets confused with the other
sequence in P2P mode and complains that it
wasn't able to flush the queues.

When removing an interface while it is in the
process of authenticating or associating, we
leak the auth_data or assoc_data, and leave
the timer pending. The timer then crashes the
system when it fires as its data is gone.
Fix this by explicitly deleting all the data
when the interface is removed. This uncovered
another bug -- this problem should have been
detected by the sta_info_flush() warning but
that function doesn't ever return non-zero,
I'll fix that in a separate patch.

* stop AP -- stop AP mode operation
This also reflects in the nl80211 API, rename
the commands there correspondingly (but keep
the old names for compatibility.)
Overall, this makes it much clearer what's going
on in the API.
Kalle developed the ath6kl changes, I created
the rest of the patch.

nothing needs to be done for monitor/AP_VLAN mode on calling
ieee80211_bss_info_change_notify -> drv_bss_info_changed with the change
flag 'BSS_CHANGED_IDLE'. 'wl1271' seems to use BSS_CHANGED_IDLE only for
STA and IBSS mode. further the non-idle state of the monitor mode is
taken care by the 'count' variable which counts non-idle interfaces.
ieee80211_idle_off(local, "in use") will be called.
this fixes the following WARNING when we have initially STA mode
(network manager running) and not associated, and change it to monitor
mode with network manager disabled and bringing up the monitor mode.
this changes the idle state from 'true' (STA unassociated) to 'false'
(MONITOR mode)
